Rey Mysterio Jr.

At 49 years old, Rey Mysterio Jr. has this physical status:

Gutiérrez made his debut in Mexico on April 30, 1989, when he was 14 years old. He was trained by his uncle Rey Misterio Sr. and wrestled early on in Mexico where he learned the Lucha Libre high flying style that has been his trademark. He had ring names such as "La Lagartija Verde (The Green Lizard)" and "Colibrí (Humming bird)" before his uncle gave him the name of Rey Misterio Jr. In 1991, Mysterio was awarded "Most Improved Wrestler" in Mexico while wrestling as Colibrí.

In Asistencia Asesoría y Administración (AAA), Mysterio feuded with Juventud Guerrera. Mysterio's uncle Misterio Sr. also took on Guerrera in a tag match: Misterio Sr. and Mysterio Jr. facing Guerrera and his father Fuerza Guerrera.

Mysterio signed with Paul Heyman's Extreme Championship Wrestling (ECW) in 1995. He debuted in September 1995 at Gangstas Paradise, defeating Psicosis, who was also making his ECW debut. A feud between the two began, which included a two out of three falls match and a Mexican Death match. Mysterio also had a series of matches with ECW-newcomer Juventud Guerrera during early 1996. He wrestled his final bout for ECW at Big Ass Extreme Bash in March 1996.

Mysterio made his World Championship Wrestling (WCW) debut on June 16, 1996, at The Great American Bash, challenging Dean Malenko for the WCW Cruiserweight Championship in a losing effort. At Bash at the Beach on July 7, he defeated Psicosis in a #1 contender's match to earn another opportunity at the Cruiserweight title. The next night, on the July 8 episode of WCW Monday Nitro, he defeated Malenko to win his first Cruiserweight Championship. He reigned as champion for three months, which included title defenses against the likes of Ultimate Dragon at Hog Wild on August 10, Malenko, and Super Caló at Fall Brawl on September 15 before he lost the title to Malenko at Halloween Havoc on October 27. Mysterio challenged Ultimate Dragon for the J-Crown Championship in a losing effort at World War 3 on November 24.

In early 1997, he began a feud with Prince Iaukea over the WCW World Television Championship, culminating in a title match against Iaukea at SuperBrawl VII on February 23, which he lost after Lord Steven Regal attacked him. Mysterio also lost a title rematch at Uncensored on March 16. He defeated Ultimate Dragon at Spring Stampede on April 6, and Yuji Yasuraoka at Slamboree on May 18. Mysterio began a feud with the New World Order (nWo), which culminated when he lost a Mexican Death match to nWo member Konnan at Road Wild on August 9. Mysterio was then involved in a feud with his real-life friend and Cruiserweight Champion Eddie Guerrero, whom he defeated in a Title vs. Mask match at Halloween Havoc on October 26 to win the Cruiserweight Championship for the second time. On the November 10 episode of Nitro, he lost the title back to Guerrero, as well as in a rematch at World War 3 on November 23. On the January 15, 1998 episode of WCW Thunder, Mysterio defeated Juventud to win his third Cruiserweight Championship, but lost it nine days later to Chris Jericho at Souled Out. After the match, Jericho continued the beating by using a toolbox he found at ringside. This storyline was used to cover Mysterio's need for a knee operation that kept him out of the ring for six months. At Bash at the Beach on July 12, Mysterio returned and defeated Jericho for his fourth Cruiserweight championship. The next night, however, the result was overturned and the belt returned to Jericho due to Dean Malenko interfering.

Later that year, Eddie Guerrero formed a Mexican stable known as the Latino World Order (LWO) (a spin off of New World Order) that included nearly every luchador in the promotion. Mysterio continually refused to join and feuded with Guerrero and the LWO members, including winning a match against longtime rival and LWO member Psicosis in a match at Road Wild on August 8. He was forced to join the group after losing a match to Eddie Guerrero. Mysterio's on-and-off tag team partner Billy Kidman joined him during the feud with LWO, wrestling against the LWO despite Mysterio being a part of the group. Mysterio faced Kidman for the Cruiserweight Championship at Starrcade on December 27, but was unsuccessful in a triangle match also involving Juventud. On January 17, 1999, at Souled Out, Mysterio failed to win the title from Kidman in a fatal four-way match that also included Psicosis and Juventud.

After the two factions of nWo reformed, they demanded that the LWO disband. Mysterio refused to take off his LWO colors and was attacked by the nWo as a result. This led to a match at SuperBrawl IX on February 21, where Mysterio and tag partner Konnan lost a "Hair vs. Mask match" against Kevin Nash and Scott Hall, forcing Mysterio to remove his mask. After the match, he phoned his uncle to tell him the news. Mysterio has publicly expressed his disappointment over being unmasked:

Mysterio later became a "giant killer" by defeating large opponents such as Kevin Nash, Bam Bam Bigelow, and Scott Norton. At Uncensored on March 14, he lost to Nash after Lex Luger interfered and helped Nash win. The next night, on the March 15 episode of Nitro, he defeated Billy Kidman to win his fifth Cruiserweight Championship. On the March 22 episode of Nitro, Mysterio got his first shot at the WCW World Heavyweight Championship against champion Ric Flair when the names of (allegedly) nearly everyone in the company were put into a hat and a lottery was held. El Dandy was the lottery winner, but he was injured, and Mysterio took the shot instead. The match ended with a disqualification win for Flair, even though Arn Anderson's interference on Flair's behalf should have theoretically disqualified Flair. The following week, Mysterio and Kidman defeated Flair's Four Horsemen stablemates Chris Benoit and Dean Malenko to win the WCW World Tag Team Championship, making Mysterio a double champion. Mysterio successfully defended his Cruiserweight Championship against his tag team partner Kidman at Spring Stampede on April 11 before losing the title on the April 19 episode of Nitro to Psicosis in a fatal four-way match that also involved Juventud Guerrera and Blitzkrieg. On the following episode of Nitro, he defeated Psicosis to win his fifth Cruiserweight Championship. At Slamboree on May 9, Mysterio and Kidman lost the World Tag Team titles to Raven and Perry Saturn in a triangle match, also involving former champions Benoit and Malenko.

In mid-1999, Mysterio and Konnan joined Master P's No Limit Soldiers and feuded with The West Texas Rednecks. At The Great American Bash on June 13, they defeated Rednecks members Curt Hennig and Bobby Duncum Jr., and at Bash at the Beach on July 11, defeated the Rednecks in a four-on-four elimination tag team match. After Master P's departure from WCW, Mysterio formed a stable with Eddie Guerrero and Billy Kidman known as the Filthy Animals, turning heel for the first and only time in his career. The Filthy Animals soon began a feud with the Dead Pool, and defeated them in a six-man tag team match at Road Wild on August 14 and at Fall Brawl on September 12. On the August 19 episode of Thunder, Mysterio lost the cruiserweight title to Lenny Lane.

On the October 18 episode of Nitro, Mysterio and Konnan defeated Harlem Heat to win the World Tag Team Championship. Mysterio, however, was injured during the match and was sidelined as a result, Kidman substituted for Mysterio and teamed with Konnan during their title defense against Harlem Heat and The First Family, in which the Filthy Animals went on to lose the title back to Harlem Heat. Mysterio returned in early 2000 and remained a steady performer, eventually joining the New Blood faction in early 2000 opposing the Millionaire's Club. On the August 14 episode of Nitro, Mysterio and Juventud defeated The Great Muta and Vampiro to win the World Tag Team Championship. They were stripped of the title after Ernest Miller pinned Disco Inferno with the stipulation that if he pinned Disco, Mysterio and Guerrera would be stripped of the title. The Filthy Animals then feuded with The Natural Born Thrillers in the fall of the year. At Fall Brawl on September 17, the Filthy Animals fought the Thrillers to a no contest in an elimination tag team match. Mysterio reformed his tag team with Kidman and the two challenged for the World Tag Team Championship in a triangle match at Halloween Havoc on October 29, facing the champions Natural Born Thrillers and The Boogie Knights in a losing effort.

At Millennium Final on November 16, Mysterio and Kidman lost to KroniK, but avenged their loss at Mayhem ten days later, defeating KroniK and Alex Wright in a handicap match. At Starrcade on December 17, The Filthy Animals lost to The Harris Brothers and Jeff Jarrett in a Bunkhouse Brawl. After this, the Filthy Animals starting feuding with Team Canada, to whom they lost in a Penalty Box match at Sin on January 14, 2001. At SuperBrawl Revenge on February 19, Mysterio unsuccessfully challenged Chavo Guerrero Jr. for the Cruiserweight Championship. Kidman and Mysterio participated in a cruiserweight tag team tournament for the newly created WCW Cruiserweight Tag Team Championship and advanced to the final round where they ended up losing to Elix Skipper and Kid Romeo. On the final episode of Nitro on March 26, they defeated Skipper and Romeo in a rematch to win the Cruiserweight Tag Team Titles before WCW was sold to the World Wrestling Federation (WWF).

After WCW closed down, Mysterio started wrestling independently in Mexico. He made his first ever Consejo Mundial de Lucha Libre appearance, debuting in an eight-man tag team match. Mysterio wrestled a total of 10 matches in CMLL before returning to the United States.

Upon his return to the US, he worked in IWA Mid-South, the Xcitement Wrestling Federation and the Heartland Wrestling Association, with the likes of Eddie Guerrero and CM Punk. Mysterio traveled to Puerto Rico for the World Wrestling Council and wrestled Eddie (Primo) Colon over the WWC World Junior Heavyweight Championship in early 2002.

In June 2002, Mysterio signed with World Wrestling Entertainment (WWE), and promos that hyped his debut began airing. The "Jr." was dropped from his name and was billed simply as Rey Mysterio.

Mysterio, with his mask, made his WWE debut on the July 25, 2002 episode of SmackDown! as a face, defeating Chavo Guerrero. He eventually began a feud with Kurt Angle, culminating in a match at SummerSlam on August 25, which Angle won after forcing Mysterio to submit to the ankle lock. He later formed a tag team with Edge; the two participated in a tournament for the newly created and SmackDown!-exclusive WWE Tag Team Championship. They lost to Kurt Angle and Chris Benoit in the finals of the tournament at No Mercy on October 20; the match was voted Match of the Year by the Wrestling Observer Newsletter. After they failed to win the title, Mysterio and Edge defeated Los Guerreros in a number one contender's match on the October 24 episode of SmackDown! to earn a title shot. Two weeks later on the November 7 episode of SmackDown!, Mysterio and Edge defeated Angle and Benoit in a two out of three falls match to win the WWE Tag Team Championship. They soon lost the WWE Tag Team Championship to Los Guerreros in a Triple Threat Elimination match that also involved former champions Angle and Benoit at Survivor Series on November 17. Shortly after the loss, Mysterio and Edge disbanded as a tag team.

On the March 6, 2003 episode of SmackDown!, Mysterio defeated Tajiri and Jamie Noble in a triple threat match to earn a shot at the WWE Cruiserweight Championship. At WrestleMania XIX, he challenged the champion Matt Hardy for the title, but lost after Shannon Moore interfered. On the May 22 episode of SmackDown!, Mysterio defeated Shannon Moore and Crash Holly in a handicap elimination match to regain the number one contendership for the Cruiserweight title, and he defeated Hardy to win his first Cruiserweight Championship (his first reign in WWE and his first singles championship in the WWE) on the June 5 episode of SmackDown!. Mysterio's reign ended when he lost the title to Tajiri on the September 25 episode of SmackDown!. Three months later, on the January 1, 2004, episode of SmackDown!, Mysterio defeated Tajiri to win his second Cruiserweight Championship. After a successful title defense against Jamie Noble at the Royal Rumble on January 25, Mysterio lost the title to Chavo Guerrero at No Way Out on February 15. At WrestleMania XX on March 14, Mysterio took part in a Cruiserweight Open for the title, but Guerrero retained the title. On the June 17 episode of SmackDown!, he defeated Chavo Classic for a record-setting third Cruiserweight Championship reign. He successfully defended the title against Chavo Guerrero at The Great American Bash on June 27. While Mysterio was Cruiserweight Champion, Spike Dudley turned heel after plowing Mysterio through a table and joined the other Dudleys before winning the Cruiserweight Championship from Mysterio on the July 29 episode of SmackDown!. At Survivor Series on November 14, he participated in a fatal four-way match for the Cruiserweight Championship involving the champion Dudley, Chavo Guerrero, and Billy Kidman. Mysterio lost when Dudley pinned Guerrero to retain.

After an unsuccessful attempt at regaining the Cruiserweight Title, Mysterio formed a tag team with Rob Van Dam, and went on to win the WWE Tag Team Championship from Kenzo Suzuki and René Duprée on the December 9 episode of SmackDown!. They successfully defended the title against the former champions at Armageddon on December 12, before losing the title to the Basham Brothers on the January 13, 2005, episode of SmackDown! after Van Dam was injured.

Mysterio then teamed up with Eddie Guerrero to win the WWE Tag Team Championship back from the Bashams at No Way Out on February 20. In a departure from traditional booking, the new champions did not defend their title at WrestleMania 21 on April 3, but instead had a match against each other which Mysterio won. He once again defeated Guerrero at Judgment Day on May 22 by disqualification. At ECW One Night Stand on June 12, Mysterio faced and defeated long-time rival Psicosis for the first time in nearly five years.

The match at WrestleMania was part of a storyline in which Guerrero turned on Mysterio and beat him up after abandoning him during a match against MNM for the WWE Tag Team Championship. After a no disqualification match against Chavo, Eddie came out and slammed Mysterio on the steel steps, displaying Eddie's increasing frustration with being unable to defeat Mysterio. Guerrero and Mysterio continued to feud, with Guerrero threatening to reveal a secret he and Mysterio shared involving Mysterio's real life son Dominik, unless Mysterio deferred to Guerrero's authority. Guerrero later revealed that, in the storyline, he was Dominik's biological father. The storyline went that Guerrero knew Mysterio was having trouble starting his own family, so Guerrero left Dominik as a baby with Mysterio and his wife Angie to raise. Guerrero threatened to take custody of Dominik, drawing up custody papers and having his lawyer present them to Mysterio. At SummerSlam on August 21, Mysterio defeated Guerrero in a ladder match for the custody of Dominik. On November 13, 2005, Eddie Guerrero was found dead in his hotel room in Minneapolis, Minnesota. That same day at a WWE "Super Show" where SmackDown! and Raw were both taped, Mysterio gave an emotional speech about Guerrero, and in a show of respect removed his mask (though he put his head down, so his face could not be seen). Mysterio went on to defeat Shawn Michaels in an interbrand match later that night. After the match, Michaels and Mysterio hugged in the ring and Mysterio pointed up to the sky, crying, in memory of Guerrero.

Mysterio participated in the main event of Survivor Series on November 27 as part of Team SmackDown! along with Randy Orton, Bobby Lashley, Batista, and John "Bradshaw" Layfield (JBL) who defeated Team Raw (Shawn Michaels, Kane, Big Show, Carlito, and Chris Masters). Mysterio then started a feud with Big Show after Mysterio eliminated Big Show at Survivor Series. Mysterio would face Big Show in a match billed as "David vs. Goliath" in a SmackDown! special show, and ended as a "no contest" when Big Show's tag team partner Kane interfered in the match. Mysterio continued to feud with Raw's World Tag Team Champions, and found a tag team partner in World Heavyweight Champion Batista. They were booked to face Raw's Kane and Big Show in a tag match at Armageddon on December 18. Before Armageddon, Batista and Mysterio defeated MNM on the December 16 episode of SmackDown! to win the WWE Tag Team Championship in a match they both dedicated to Eddie Guerrero. Mysterio and Batista's match with Big Show and Kane was then billed as "Champions vs. Champions," which they lost. On the December 30 episode of SmackDown!, MNM invoked their rematch clause, defeating Batista and Mysterio after interference from Mark Henry to regain the WWE Tag Team Championship. The following week, Mysterio and Batista received their rematch for the titles in a steel cage match, which they lost after interference by Henry. On the January 13 episode of SmackDown!, Mysterio was involved in a 20-man battle royal for the vacant World Heavyweight Championship, but was eliminated by Henry.

Mysterio was the second entrant in the Royal Rumble match on January 29, 2006, setting a record by lasting 62 minutes, winning the match, and earning a world title shot by last eliminating Randy Orton. Orton urged him to put the title shot at stake in a match at No Way Out. Over the following weeks, Orton made disparaging remarks about Eddie Guerrero, which many felt the comments were unwarranted and distasteful in the wake of Guerrero's death. Orton won at No Way Out on February 19, earning Mysterio's title shot for the World Heavyweight Championship at WrestleMania 22 on April 2. General Manager Theodore Long re-added Mysterio to the WrestleMania title match however, making it a triple threat match between Orton, Mysterio, and then-champion, Kurt Angle. At WrestleMania, Mysterio pinned Orton to become the new World Heavyweight Champion. On the following episode of SmackDown!, Mysterio – billed as an "underdog champion", made his first successful World Heavyweight title defense against Orton. Mysterio retained the title again during a WrestleMania rematch on SmackDown! against Angle three weeks later.

Mysterio quickly moved into a feud with the United States Champion John "Bradshaw" Layfield (JBL). The rivalry kicked off after JBL, celebrating his U.S. Championship win, stated he deserved the World Heavyweight title. This feud saw Mysterio face off against three opponents chosen by JBL in the three weeks leading up to their title match at Judgment Day. Mysterio was defeated by Mark Henry and The Great Khali in separate non-title matches before wrestling Kane to a "no contest"; Mysterio retained his title against JBL at Judgment Day on May 21. The feud intensified when JBL lost the United States Championship to Bobby Lashley five days later on SmackDown! after being tricked by Mysterio to take on all comers like Mysterio himself had. JBL vowed that if he did not win his rematch against Mysterio, he would quit SmackDown!. In their main event match, Mysterio retained the World Heavyweight Championship, causing JBL to leave SmackDown!, until ECW One Night Stand, when he announced his return as a color commentator. Mysterio was booked to defend against ECW wrestler Sabu at One Night Stand. In the weeks leading up to his title defense, Mysterio defeated Cruiserweight Champion Gregory Helms in a Champion vs. Champion match, and lost to Rob Van Dam at WWE vs. ECW Head-to-Head on June 7. At One Night Stand on June 11, Mysterio retained the title, after he and Sabu were ruled unable to continue following a triple jump DDT through a table by Sabu. Mysterio then retained his title in a match against Mark Henry, winning by disqualification after Chavo Guerrero handed Henry a chair and Mysterio acted as if he was hit, a tactic for which Eddie Guerrero was known.

Mysterio began a feud with King Booker after Booker won a battle royal to become the number one contender for the World Heavyweight Championship. Booker attacked Mysterio from behind backstage with the help of Booker's wife Queen Sharmell. The next week on SmackDown!, Mysterio gained revenge by attacking Booker and his "court". This rivalry continued for several weeks and saw Mysterio defeating Booker's court member William Regal on an episode of SmackDown!, moments before attacking the challenger and hitting him with a 619 around the steel post. On July 23 at The Great American Bash, Mysterio lost the World Heavyweight Championship to King Booker after Chavo interfered in the match and turned on Mysterio, hitting him with a steel chair. Guerrero cost Mysterio his rematch the following week. This culminated in a match at SummerSlam on August 20, where Mysterio lost to Guerrero after Vickie Guerrero tried to stop both men from fighting, but accidentally knocked Mysterio off the top turnbuckle. Vickie then along with Chavo turned on Mysterio after she hit him in the back with a steel chair and gave him an injury, thus, siding with Guerrero. Mysterio then defeated Guerrero in a Falls Count Anywhere match at No Mercy on October 8. Subsequently, Guerrero challenged Mysterio to an "I quit" match for the October 20 edition of SmackDown!. In that match (which Mysterio lost), Guerrero injured Mysterio's knee, using the match to write Mysterio out of the storyline for a while to get knee surgery.

Mysterio made his in-ring return at SummerSlam on August 26, 2007, defeating Guerrero, after Guerrero obsessed over Mysterio's return as well as wanting to injure Mysterio again. On the August 31 episode of SmackDown!, Mysterio won a "Championship Competition" to become the number one contender for the World Heavyweight Championship, defeating Batista and Finlay. On the September 7 episode of SmackDown!, Mysterio had an "I Quit" match with Guerrero, which he won after hitting Guerrero's knee with a steel chair repeatedly in a similar manner to which Mysterio had been put out of action, to end the feud. Mysterio then began a feud with The Great Khali, which led to a World Heavyweight Championship match at Unforgiven on September 16. The match was later made a Triple Threat match, also involving Batista, who won it.

Mysterio then began a feud with Finlay, an opponent chosen by JBL. The rivalry was marked as "Fight vs. Flight", contrasting the fighting styles of both wrestlers – Finlay's physicality, versus the high-flying Mysterio. After fighting to a "no contest" at No Mercy on October 7, followed by a double-disqualification in a number one contender's match for Batista's World Heavyweight Championship on the next SmackDown! he defeated Finlay in a Stretcher match at Cyber Sunday on October 28. During this feud, he lost a match to Finlay on the November 9 episode of SmackDown! and was part of the winning team at Survivor Series on November 18 which consisted of both wrestlers on opposing sides (although Mysterio was second to be eliminated).

He re-entered the World Heavyweight Championship picture on the January 4, 2008 episode of SmackDown! when he won a Beat the Clock challenge for a chance to face the World Heavyweight Champion Edge at the Royal Rumble. He was unsuccessful in winning the championship at the event on January 27. WWE's official website announced on February 14 that Mysterio suffered a biceps injury during an overseas tour. Despite the injury, Mysterio faced Edge for the title in a rematch at No Way Out on February 17, which he lost. On the February 22 episode of SmackDown, Mysterio announced that his injury would keep him out of action for at least six months, and he eventually underwent three surgeries within the space of a month.

Mysterio made his return on the June 23, 2008, episode of Raw, as the first wrestler to be drafted in the 2008 WWE Draft from SmackDown brand to the Raw brand. Mysterio made his Raw in-ring debut on July 7, pinning Santino Marella after a 619. General Manager Mike Adamle announced that John Cena was injured and that Mysterio would replace him in the Championship Scramble at Unforgiven. The next week, Mysterio made his return to Raw after an extended absence by attacking Kane, turning back numerous claims that Kane had "ended his career". Mysterio then made his in-ring return at Unforgiven on September 7, competing in the World Heavyweight Championship scramble match, which was won by Chris Jericho. Mysterio put his mask on the line in a match at No Mercy on October 5, which he won by disqualification after Kane attacked him with a steel chair. He defeated Kane again at Cyber Sunday on October 26, this time in a No Holds Barred match, and again at Survivor Series on November 23, when the pair were on opposing sides in a five-on-five elimination match. At No Way Out on February 15, 2009, Mysterio competed in the Elimination Chamber match for the World Heavyweight Championship, but was eliminated by Edge when the two were the last men in the match.

Later, John "Bradshaw" Layfield (JBL) accepted Mysterio's challenge for Layfield's Intercontinental Championship at WrestleMania 25 on April 5 which Mysterio won in 21 seconds. His win made Mysterio the twenty-first Triple Crown Champion in WWE history. Mysterio was drafted back to the SmackDown brand during the 2009 WWE Draft on the April 13 episode of Raw, in the process making the Intercontinental Championship exclusive to SmackDown for the first time since August 2002. He then entered into an extensive feud with Chris Jericho, retaining his title against him at Judgment Day on May 17. At Extreme Rules on June 7, Jericho unmasked Mysterio and pinned him for the Intercontinental Championship; while Mysterio managed to cover his face after being unmasked, Jericho took the opportunity to roll him up and win the title. Mysterio and Jericho were booked in a Title vs. Mask match that was scheduled for The Bash on June 28, which Mysterio won after tricking Jericho with a second mask. He then moved into a feud with Dolph Ziggler, whom he retained the title against at both Night of Champions on July 26 and SummerSlam on August 23. On August 2, WWE announced that Mysterio would be suspended for 30 days, effective September 2, for violating the company's Wellness Policy. In an interview with Mexican newspaper Record, Mysterio stated that he was suspended for a drug he was using for his knee and arm. Mysterio stated that he had a prescription for the drug, but was unable to produce it in time to prevent his suspension due to being on vacation and doing a promotional tour. On the September 4 episode of SmackDown (taped on September 1), Mysterio lost the Intercontinental Championship to John Morrison.

Mysterio returned from suspension at Hell in a Cell on October 4, teaming with former tag team partner Batista to face Jeri-Show (Chris Jericho and Big Show) for the Unified WWE Tag Team Championship in a losing effort. At Bragging Rights on October 25, Mysterio was unsuccessful in winning the World Heavyweight Championship in a fatal four-way match involving Batista, CM Punk, and then-champion The Undertaker. During the match, Mysterio broke up Batista's pin on Undertaker costing him the match and the title. After the match, Batista attacked Mysterio, ending their alliance. At Survivor Series on November 22, he lost to Batista by referee stoppage after Batista performed three Batista Bombs on him. Mysterio lost to Batista again in a street fight on the December 11 episode of SmackDown. A week later, Mysterio defeated Batista and was named the number one contender for the World Heavyweight Championship, but his title match against The Undertaker on the December 25 episode of SmackDown ended in a no contest after Batista interfered. On January 1, Mysterio participated in a Beat the Clock Tournament for a World Heavyweight Championship match at the Royal Rumble. In the tournament, he defeated his former rival Chris Jericho in the quickest time, and prevented Batista from beating it by interfering in his match. This led to a number one contender's match between the duo the following week, which also ended in a no contest following interference from the Undertaker. The following week in a re-match, Mysterio defeated Batista in a Steel Cage match, but failed to win the championship at the Royal Rumble on January 31, 2010.

Mysterio then qualified for an Elimination Chamber match for the World Heavyweight Championship at Elimination Chamber on February 21. In the weeks preceding the event, Mysterio began a feud with CM Punk that also involved Punk's Straight Edge Society. During the Elimination Chamber match, Mysterio eliminated Punk but was eliminated by John Morrison. Mysterio continued to feud with Punk, costing him a Money in the Bank qualifying match and defeating SES member Luke Gallows. During the on-screen celebration of Mysterio's daughter's ninth birthday, Punk interrupted, taunting Mysterio and challenging him to a match at WrestleMania XXVI, which Mysterio accepted. Punk later added the stipulation that if Mysterio were to lose at WrestleMania, he would be forced to join the SES. Mysterio defeated Punk at WrestleMania on March 28. At Extreme Rules on April 25, Mysterio lost to Punk with the stipulation that Punk would have his head shaved if Mysterio won. At Over the Limit on May 23, Mysterio faced CM Punk again with both previous stipulations in place (Mysterio's allegiance to the SES and Punk's hair); Mysterio defeated Punk, resulting in Punk's head being shaved.

On the May 28 episode of SmackDown, Mysterio unsuccessfully fought The Undertaker to qualify for the World Heavyweight Championship title match at Fatal 4-Way. The Undertaker suffered a legitimate injury during the match, and a storyline was introduced to explain his absence on television, stating he had been found in a vegetative state by his brother Kane. On the June 4 episode of SmackDown, Mysterio won a battle royal to earn The Undertaker's place at Fatal 4-Way by last eliminating Kane, and at the event on June 20, defeated Jack Swagger, Big Show, and CM Punk to win the World Heavyweight Championship for the second time. At Money in the Bank on June 20, Mysterio retained the World Heavyweight Championship against Swagger, however, Swagger attacked him after the match. Kane, who had won the SmackDown Money in the Bank ladder match earlier that night, cashed in for a title shot and quickly defeated Mysterio to win the World Heavyweight Championship after it had appeared that he was saving Mysterio from Swagger's attack. Kane later blamed Mysterio for The Undertaker's fictional injuries. On the July 23 episode of SmackDown, Mysterio defeated Swagger in a two out of three falls match to remain the #1 contender for the World Heavyweight Championship, earning a title match against Kane at SummerSlam. Kane defeated Mysterio at SummerSlam on August 15, and after the match, the Undertaker returned to exonerate Mysterio and blame Kane.

Five days later on the August 20 episode of SmackDown, Mysterio lost to the debuting Alberto Del Rio by submission. Del Rio, however, continued his attack after the match, sidelining Mysterio for a month, in which time Del Rio would taunt him. The following week a feud was sparked between the two, when Del Rio attacked Mysterio and broke his wrist following a match with Kane. On the October 8 episode of SmackDown, Mysterio defeated Del Rio, and thus ending his undefeated streak. At Bragging Rights on October 24, Mysterio represented Team SmackDown, and despite being attacked by teammate Del Rio, he and Edge managed to defeat the rest of Team Raw, giving Team SmackDown the victory. At Survivor Series on November 21, Mysterio led a team to victory over Team Del Rio, and at Tables, Ladders & Chairs on December 19, both were part of a fatal four-way Tables, Ladders, and Chairs match for the World Heavyweight Championship, won by Edge. His feud with Del Rio culminated on the January 7, 2011, episode of SmackDown in a two out of three falls match, which Del Rio won by countout.

On the January 21 episode of SmackDown, Mysterio defeated Cody Rhodes and broke his nose when he hit Rhodes with a 619 with his exposed knee brace, thus sparking a feud. At Elimination Chamber on February 20, he competed in the Elimination Chamber match for the World Heavyweight Championship, making it to the final two but was eliminated by Edge. On the February 25 episode of SmackDown, Mysterio was tricked and attacked by Cody Rhodes and his father, Dusty Rhodes, resulting in Mysterio being unmasked by Rhodes. At WrestleMania XXVII on April 3, Mysterio lost to Rhodes. At Extreme Rules on May 1, Mysterio defeated Rhodes in a Falls Count Anywhere match to end the feud.

In the 2011 WWE Draft, Mysterio was drafted to the Raw brand. On the May 9 episode of Raw, Mysterio lost a triple threat match to determine the number one contender for the WWE Championship. Following the match, Mysterio was attacked by R-Truth, which led to a match between the two at Over the Limit, which R-Truth won. In May, Mysterio started feuding with CM Punk, with the pair exchanging victories on consecutive episodes of Raw. The feud culminated in a singles match on June 19 at Capitol Punishment, where Punk emerged victorious. On July 17 at Money in the Bank, Mysterio failed to capture the Raw Money in the Bank briefcase, as the match was won by old rival Alberto Del Rio. The following night on Raw, Mysterio took part in a tournament for the vacant WWE Championship and advanced to the finals. On the July 25 episode of Raw, Mysterio defeated The Miz in the final to win his first WWE Championship, but he lost the title to John Cena later that night. On the August 15 episode of Raw, Mysterio received a rematch for the WWE Championship against new champion Alberto Del Rio, but lost via submission. Mysterio suffered an injury in late August. Mysterio returned at the Slammy Awards to present the Superstar of the Year Award to CM Punk.

On April 26, 2012, WWE reported that Mysterio had been suspended for 60 days due to his second violation of the company's Talent Wellness Program policy and that his suspension would expire on June 25.

Mysterio returned on the July 16 episode of Raw, saving Zack Ryder from his old rival Alberto Del Rio. On August 19 at SummerSlam, Mysterio unsuccessfully challenged The Miz for the Intercontinental Championship. During the match, Mysterio suffered a legitimate concussion, rendering him inactive for a week, but he returned to SmackDown on the August 31 episode. On September 16 at Night Of Champions, Mysterio failed again to capture the Intercontinental Championship from The Miz in a fatal four-way match, also involving Cody Rhodes and Sin Cara. The following night on Raw, Mysterio and Sin Cara teamed up to defeat Primo and Epico in a tag team match, after which they were attacked by The Prime Time Players (Darren Young and Titus O'Neil). According to Mysterio, he took the decision to leave WWE when he saw no creative direction about his tag team with Sin Cara.

In October, Mysterio and Sin Cara entered a tournament to determine the number one contenders to the WWE Tag Team Championship, defeating Primo and Epico in the first round and the Prime Time Players in the semi-finals. Mysterio and Sin Cara were set to face the team of Cody Rhodes and Damien Sandow on the October 15 episode of Raw, but the match was postponed due to Mysterio legitimately suffering from effects of the stomach flu. The final took place the following week, on October 22, where he and Sin Cara were defeated by Rhodes and Sandow. On November 18 at Survivor Series, Mysterio and Sin Cara were victorious in a 10-man elimination tag team match alongside Brodus Clay, Justin Gabriel, and Tyson Kidd against Primo, Epico, the Prime Time Players, and Tensai. On December 16 at TLC: Tables, Ladders & Chairs, Mysterio and Sin Cara lost to Team Rhodes Scholars (Cody Rhodes and Damien Sandow) in a #1 contenders Table match for the WWE Tag Team Championship. Two days later on SmackDown, Mysterio was sidelined with a storyline injury when he and Sin Cara were attacked by The Shield. This was used to write them off television, as Mysterio was taking some time off, and Sin Cara underwent a knee surgery. On January 27, 2013, at Royal Rumble, he entered at #14 but was eliminated by Wade Barrett. In March, Mysterio took another leave of absence due to a legitimate knee injury, explained in storyline as an attack by Mark Henry.

After eight months, Mysterio returned at a WWE live event on October 17, 2013, and returned to television as part of the Spanish commentary team at Hell in a Cell on October 27. On the November 18 episode of Raw, Mysterio saved CM Punk and Daniel Bryan from an attack by The Wyatt Family and The Real Americans (Jack Swagger and Antonio Cesaro), which led to Mysterio being part of a 10-man elimination tag team match at Survivor Series on November 24, in which Mysterio's team lost after he was eliminated by sole survivor Roman Reigns. At TLC: Tables, Ladders and Chairs on December 15, Mysterio and Big Show unsuccessfully challenged Cody Rhodes and Goldust for the WWE Tag Team Championship in a fatal four-way match also involving RybAxel (Ryback and Curtis Axel) and The Real Americans.

On the April 7 episode of Raw, he made an appearance and lost to a returning Bad News Barrett, subsequently deciding to take time off to heal a wrist injury. During his hiatus, it was reported that Mysterio wanted to leave WWE, but the promotion had extended his contract without his approval. Mysterio did not return to WWE programming, and instead appeared in a video message at AAA's Triplemanía XXII and also visited Lucha Underground. On February 26, 2015, WWE officially announced that Mysterio's WWE contract had expired, ending his nearly 13-year tenure with the company.

On March 3, 2015, five days after being released from WWE, it was announced that Mysterio had agreed to work for Lucha Libre AAA Worldwide for the first time since 1995. He made his in-ring return as part of AAA's 2015 pay-per-view Rey de Reyes ("King of Kings") on March 18, 2015. Mysterio teamed up with Myzteziz (formerly Sin Cara in WWE) to defeat the Los Perros del Mal team of El Hijo del Perro Aguayo and Pentagón Jr., with Mysterio scoring the winning pin. This match is notorious for showing wrestler Perro Aguayo Jr.'s death in the ring following a drop kick from Mysterio. Mysterio delivered a dropkick to Perro's back, causing him to fall to the second rope, setting him up for Mysterio's signature "619" wrestling move, which involve Mysterio running towards the rope, grabbing it, and spinning around 180°, hitting the person on the face with his legs. Mysterio, seeing that something was wrong due to Perro becoming limp, purposely missed. The other wrestlers continued performing while each coming up and checking on Perro. They quickly finished the match after realizing that something serious had happened. The ref, wrestlers, and lockerroom crew came out and took Perro out using a piece of plywood. He was pronounced dead by the doctors later that night. His official death was ruled as cardiac arrest.

On May 24, 2015, Mysterio came together with Myzteziz and El Patrón Alberto to form the "Dream Team" for AAA's Lucha Libre World Cup. The trio eventually won the tournament, defeating Johnny Mundo, Matt Hardy and Mr. Anderson in the finals with Mysterio pinning Mundo for the win. For Triplemanía XXIII, AAA's biggest show of the year, a "dream match" between Mysterio and Myzteziz took place. Both wrestlers teamed during their time in WWE and AAA but had never competed against each other. Mysterio was victorious, forcing Myzteziz to submit to a Fujiwara armbar. After the match, Myzteziz turned rudo and sprayed mist at Mysterio's face and challenged him to a Lucha de Apuestas. In early February 2016, AAA announced that Mysterio had left AAA due to financial issues between Mysterio and AAA. Despite not working directly for AAA, Mysterio Jr. participated in the 2016 Lucha Libre World Cup alongside Dr. Wagner Jr. and Dragon Azteca Jr., known as "Team Mexico International" the trio finished in third place.

Mysterio has also appeared on a number of independent shows, facing Amazing Red in House of Glory, Ricochet in Drive Wrestling, P. J. Black in Black Destiny Wrestling, AJ Styles at a 5 Star Wrestling show in the UK, Alberto El Patron in Qatar Pro Wrestling, amongst others.

Mysterio faced fellow WWE alumnus Kurt Angle on March 20, 2016 for the upstart URFight promotion. Mysterio successfully defeated Angle in a two-falls match with assistance from rapper Riff Raff. In January 2017, Mysterio noted in an interview that he may consider opening up his own wrestling school. During the interview, he said: "I just thought I would never have the time. Now being able to make that time – to not have the busy schedule I had with WWE – gives me plenty of time to be a family man. I'm hoping that this time I'm spending with my son will open up that idea again and create a Rey Mysterio Wrestling school". On April 30, 2017, at the WCPW Pro Wrestling World Cup – Mexican Qualifying Round, Mysterio won the Mexico Leg with Penta El Zero M defeating Alberto El Patron in the semi-finals, and defeating longtime rival Juventud Guerrera in the finals. In Round 16, Mysterio lost to the English qualifier Will Ospreay.

Black and Cortez Castro, Joey Ryan and Mr. Cisco in a 4-way Trio Tag Team Elimination Match for the Lucha Underground Trios Championship.

On January 31, 2016, at Ultima Lucha Dos, Rey Mysterio defeated Prince Puma. On April 9, 2016 Mysterio was in an Aztec Warfare match where he eliminated Matanza Cueto after Mysterio was eliminated by Johnny Mundo.

During an interview with Title Match Wrestling in December 2016, Mysterio was asked if he would ever return to WWE, Mysterio replied:

At the end of Season 3, Mysterio was seen locked inside a cell with Matanza Cueto, implying that he had been killed off and would not be returning for Season 4. It was confirmed that Mysterio would not return for Season 4 as he had chosen not to renew his contract with Lucha Underground.

Rey Mysterio made his New Japan Pro-Wrestling (NJPW) debut on June 9, 2018 as part of NJPW's Dominion 6.9 in Osaka-jo Hall show. Mysterio teamed up with Jushin Thunder Liger and Hiroshi Tanahashi, losing to the Bullet Club team of Cody, Marty Scurll and Adam Page.

After being drafted to Raw as part of the Superstar Shake-up, Mysterio won the title at Money in the Bank, becoming the twenty-first WWE Grand Slam Champion in the process. However, on the June 3 episode of Raw, Mysterio announced that he would return the title to Joe due to suffering an injury. Mysterio returned from injury one month later.

On the September 23 episode of Raw, Mysterio won a fatal five-way elimination match, which led to Mysterio earning a Universal Championship opportunity against Seth Rollins. However, the following week on Raw, Mysterio and Dominik were brutally attacked by Brock Lesnar, resulting in a storyline injury for the latter. On the October 4 episode of SmackDown, Mysterio assisted the debut of Cain Velasquez to attack Lesnar after the latter's WWE Championship win. At Crown Jewel on October 31, Lesnar defeated Velasquez by submission and continued to apply the Kimura Lock after the match had concluded until Mysterio attacked Lesnar with a chair.

On the April 20 episode of Raw, Mysterio defeated Murphy to qualify for the Money in the Bank ladder match. At Money in the Bank on May 10, Mysterio failed to win the match. On the following episode of Raw, Mysterio and Aleister Black fought Seth Rollins and Murphy to a disqualification when Rollins pulled Mysterio off of the ring apron and used the corner of the steel steps to pierce Mysterio's eye, taking him out of action. This resulted in speculation that Mysterio would "retire", following weeks of being mocked by Rollins. However, Mysterio and Dominik later began targeting Rollins, with Mysterio challenging Rollins to an Eye for an Eye match at The Horror Show at Extreme Rules; the match could be won by "removing" an opponent's eyeball. At the event on July 19, Mysterio lost the match in a gruesome manner, but doctors believed his eye was able to be saved. At Payback on August 30, Mysterio and his son Dominik Mysterio defeated Rollins and Murphy. As part of the 2020 Draft, Mysterio was drafted to the SmackDown brand.

At WrestleMania Backlash on May 16, Mysterio and Dominik defeated Ziggler and Roode to win the SmackDown Tag Team Championship, becoming the first ever father-son tag team champions in WWE history. On the June 4 episode of SmackDown, the Mysterios retained their titles against The Usos, albeit with controversy as Jimmy's shoulder was lifted although the referee wasn't aware. After Adam Pearce and Sonya Deville granted a rematch later that same night, the Mysterios again retained their titles after Roman Reigns interfered and attacked the Mysterios, causing a disqualification, and both were assaulted by Reigns afterwards. The following week on SmackDown, Rey called out Reigns for attacking Dominik, and challenged Reigns to a Hell in a Cell match at the namesake pay-per-view on June 20, but before Reigns could answer, Rey attacked Reigns with a kendo stick, but was ultimately overpowered, and while Dominik joined the brawl, Reigns powerbombed Dominik over the top rope and out of the ring. The next day on Talking Smack, Paul Heyman, Reigns' "special council", formally accepted Rey's challenge on Reigns's behalf.

The Mysterios soon began a feud with The Judgment Day (Finn Balor, Damian Priest, and Rhea Ripley), who repeatedly attempted to have Dominik join the stable and betray Rey. At SummerSlam on July 30, the Mysterios defeated Bálor and Priest in a no disqualification match due to interference from a returning Edge, the Judgment Day's former leader.
