The AAA Mega Championship (Campeonato Mega de AAA) is the primary singles championship of Lucha Libre AAA Worldwide (AAA), one of Mexico’s leading professional wrestling promotions. Created in 2007 to unify several of the company’s earlier top titles into a single crown, it has since become a fixture of Triplemanía, AAA’s flagship annual event, and the championship most closely associated with the promotion’s main event scene.
While rooted in Mexican lucha libre, the Mega Championship has grown into a widely recognised world title, often defended beyond AAA’s own events and carried by both homegrown stars and international names — reflecting the promotion’s increasingly global outlook.
Origins and Creation
The AAA Mega Championship was established on 16 September 2007 to unify several of AAA’s previous major singles titles — the Mexican National Heavyweight Championship, UWA World Light Heavyweight Championship, UWA World Heavyweight Championship, and IWC World Heavyweight Championship — into one undisputed championship.
This gave AAA a single, definitive world title in place of its scattered top belts, mirroring how other major modern promotions like WWE or AEW (Then ROH, likely) operate.
The inaugural champion was El Mesías (Ricky Banderas/Mil Muertes), who defeated Chessman in the tournament final at Verano de Escándalo 2007. Mesías went on to become the belt’s dominant early figure, holding it a record four times during its formative years.

While many wrestlers have held the Mega Championship, several reigns are especially significant to its history:
El Mesías (2007–2011) — The Founding Champion
Mesías set the standard for the title, winning the inaugural tournament and later reclaiming it from rivals like Cibernético and Dr. Wagner Jr. He defended it exclusively on AAA shows in Mexico, establishing the championship as AAA’s main singles prize.
Dr. Wagner Jr. (2009–2010) — A Legend’s Crowning Moment
At Triplemanía XVII in June 2009, Dr. Wagner Jr. defeated Mesías in a high-profile main event that brought major attention to the title. Wagner held it for over a year before losing to L.A. Park in 2010, showing that AAA’s top championship could headline with Mexico’s most renowned veterans.
Jeff Jarrett (2011 & 2018) — International Shockwaves
Jeff Jarrett became the first American to win the belt at Triplemanía XIX in 2011, defeating El Zorro with help from Karen Jarrett and La Sociedad. He carried the title onto TNA Impact Wrestling broadcasts, giving it rare U.S. television exposure. In 2018, he briefly held it again at Triplemanía XXVI in a three-way against Dr. Wagner Jr. and Rey Fénix, before losing it shortly after.
Texano Jr. (2012–2014) — A Long-Term Champion
Texano Jr. defeated El Mesías at Guerra de Titanes 2012 and held the belt for 730 days, one of the longest reigns in its history. He defended it primarily on AAA events in Mexico before losing to Alberto El Patrón at Guerra de Titanes 2014.
Alberto El Patrón (2014–2015) — A Global Name
Fresh from WWE, Alberto El Patrón brought international visibility when he defeated Texano Jr. for the championship. He appeared with the belt during Ring of Honor shows in the United States before vacating it in early 2015 upon re-signing with WWE.
Johnny Mundo (2017) — The Triple Crown Moment
Johnny Mundo won the Mega Championship from El Texano Jr. at Rey de Reyes on March 19, 2017, while already holding the Latin American and World Cruiserweight titles. He became the first wrestler in AAA history to hold all three singles championships simultaneously, before losing the Mega title to Dr. Wagner Jr. at Triplemanía XXV later that year.
Rey Fénix (2018–2019) — The High-Flying Fan Favourite
Rey Fénix captured the title from Jeff Jarrett at Heroes Inmortales on 28 October 2018, becoming one of the youngest champions in the belt’s history. He defended the title on AAA shows and various U.S. independent promotions, adding a surge of excitement and international attention before losing to Kenny Omega at Heroes Inmortales XIII in October 2019.
Kenny Omega (2019–2021) — The AEW Era
As part of AAA’s working relationship with All Elite Wrestling, Kenny Omega captured the Mega Championship from Rey Fénix. He defended it at AAA pay-per-views and on AEW television, including matches against Sammy Guevara, Jack Evans and Laredo Kid, giving the belt a high international profile before vacating it due to injury in late 2021.
El Hijo del Vikingo (2021–2025) — The Record Breaker
Crowned in a five-way match at Triplemanía Regia II (December 2021), Vikingo defended the championship for over 1,200 days — the longest reign in its history. He carried it to AEW, ROH, IMPACT and independent U.S. promotions, raising its global visibility before losing to Dominik Mysterio in 2025.
Dominik Mysterio (2025–present) — A WWE Crossover Moment
In a rare cross-promotional title change, Dominik Mysterio defeated Vikingo at the AAA x WWE “Worlds Collide” event in Las Vegas (September 2025). It was the first time the Mega Championship changed hands on a WWE-branded show, and it marked the beginning of a new interpromotional chapter for the title.
Legacy & Significance
Among AAA’s various championships — including its World Tag Team, World Trios, Latin American and Cruiserweight titles — the Mega Championship is designated as the company’s primary singles world championship. It regularly headlines Triplemanía and has been held by many of the promotion’s top stars.
Unlike most world titles, the Mega Championship has often been defended outside its home promotion. AAA has placed the title on wrestlers from TNA, AEW, ROH, IMPACT and WWE, using it to build international visibility and cross-promotional goodwill. This has given the championship a reputation as one of the most globally travelled titles in wrestling, while still remaining the centrepiece of AAA’s identity.
AAA and CMLL — Two Pillars of Lucha Libre
AAA’s status is often compared with its long-time counterpart CMLL (Consejo Mundial de Lucha Libre) — the oldest professional wrestling promotion in the world, founded in 1933. While CMLL is known for its traditional, heritage-driven approach and keeps its world titles largely within Mexico, AAA has focused on television presentation, spectacle and international crossovers, with the Mega Championship embodying that philosophy. Both promotions remain central to Mexican wrestling and are seen as two contrasting but equally important institutions.
Dominik Mysterio — Continuing the Mysterio Legacy
The current AAA Mega Champion is Dominik Mysterio, who captured the title from El Hijo del Vikingo at the AAA x WWE: Worlds Collide event in Las Vegas in September 2025. The victory marked a historic first — the Mega Championship changing hands on a WWE-branded show — and signalled the beginning of a new interpromotional chapter for the title.
Dominik’s reign carries extra significance because of his family name. His father, Rey Mysterio, is widely regarded as one of the greatest luchadores of all time and spent much of the 1990s and early 2010s wrestling in AAA, where he first made his name before becoming an international star. Rey also made a short return run in CMLL in 2011, further cementing his ties to both of Mexico’s major promotions.
With Dominik now holding the company’s top prize, many fans expect Rey to return to AAA to challenge his son — a generational showdown that would not only mark Rey’s full-circle return to the promotion where he made his name, but also stand as one of the most high-profile matches in the history of the Mega Championship.
Nearly two decades after its creation, the AAA Mega Championship has become one of the most recognisable symbols of modern lucha libre. Born from the unification of several older titles, it has grown into a world championship defended across borders, carried by both homegrown icons and international stars.Discover the history of the AAA Mega Championship — AAA’s top world title, defended globally by legends, icons and rising stars.
Its current chapter — led by Dominik Mysterio, the son of AAA alumnus Rey Mysterio — highlights how the title continues to evolve, bridging generations and even promotions. Whether defended on AAA’s own grand stages or in cross-promotional settings, the Mega Championship remains the clearest marker of who stands at the top of AAA.
As the landscape of professional wrestling shifts around it, the belt endures — a constant thread through AAA’s past, present and future.
