San Diego, California · WWE · AAA · third-generation Mysterio · 2020–present
Dominik Mysterio was on WWE television eight years before his first match — as the eight-year-old at the centre of the 2005 Eddie Guerrero custody storyline — and the arc of his career since has been the slow, deliberate weaponising of that familiarity. The dutiful son who debuted against Seth Rollins at SummerSlam 2020 and won tag team gold with his father became, from September 3, 2022, the Judgment Day's “Dirty Dom”: the most reliably booed man in the company, a two-time Intercontinental Champion, and — as of August 31, 2026 — the reigning AAA Mega Champion, a title he has now held since September 12, 2025. 204days in his first Intercontinental Championship reign, ended by John Cena on the November 10, 2025 RawHe is a third-generation wrestler — grandson of Rey Mysterio Sr., son of Rey Mysterio — who has built a career on being the family disappointment on purpose.
The title record is stronger than the sneer suggests. He and Rey became the first father-son tag team champions in WWE history at WrestleMania Backlash on May 16, 2021. The heel run brought two NXT North American Championship reigns in 2023, then the Intercontinental Championship at WrestleMania 41 on April 20, 2025 — winning the fatal four-way by pinning Bron Breakker after Finn Balor's Coup de Grace inadvertently set it up, the accident the next year of Judgment Day television was built on. 2Intercontinental reigns — 204 days, then 93, both ended by men he had wrongedHe held it 204 days, lost it to John Cena on the November 10, 2025 Raw — the win that completed Cena's Grand Slam — and took it back 19 days later at Survivor Series in his hometown of San Diego, one of the final losses of Cena's career. The AAA Mega Championship came in between: after AJ Styles' involvement helped wreck his first challenge at Triplemania XXXIII in August 2025, he beat El Hijo del Vikingo for it at Worlds Collide in Las Vegas on September 12, 2025, and has defended it since, including against Vikingo at Rey de Reyes on March 14, 2026.
The 2026 story is consequences. On the March 2 Raw he lost the Intercontinental Championship to Penta when Finn Balor stopped JD McDonagh handing him the hammer he wanted; the confrontation that followed got Balor beaten down and expelled from the Judgment Day, and got Dominik a date with The Demon at WrestleMania 42, where Balor put him through a table with the Coup de Grace to win their April 19 street fight. 100Kthe dollars Danhausen stole from the Judgment Day and then won outright in the SummerSlam Human Monies on a Pole matchThe summer brought farce instead: Danhausen stole $100,000 from the Judgment Day, WWE literalised the dispute by hanging the cash above the ring at SummerSlam, and Danhausen climbed the pole on August 2. Dominik still leads what remains of the Judgment Day on Raw — McDonagh, Liv Morgan, Raquel Rodriguez — and his September is already booked: El Grande Americano challenges for the AAA Mega Championship at Triplemania 34 in Mexico City on September 13.
Sixteen documented bouts — the title changes, the family matches and the Danhausen farce.

Two acts: the family, and the family he chose to spite it.
Rey Mysterio, Dominik Mysterio
The father-son act that made history at WrestleMania Backlash on May 16, 2021 — the first father-son tag team champions WWE has ever had. It ended the night of Clash at the Castle, September 3, 2022, when Dominik attacked both Edge and his own father, and it stayed dead through the WrestleMania 39 singles match Rey won on April 1, 2023.
Dominik Mysterio, JD McDonagh, Liv Morgan, Raquel Rodriguez; formerly Finn Balor, Damian Priest, Rhea Ripley, Edge
He joined the group that recruited him away from his father on September 3, 2022 and outlasted every bigger name in it: Edge voted out in 2022, Priest expelled in 2024, Rhea Ripley drifting off, and Finn Balor beaten down and ousted in March 2026 after he cost Dominik the Intercontinental Championship. What began as Dominik's adoptive family is now effectively his faction — which the Danhausen money storyline treats as a small criminal enterprise with $100,000 in petty cash.
One ring name, three characters: the storyline kid (2005) → the dutiful son (2019–2022) → Dirty Dom (2022–present).
Eight years old, on television as the child at the centre of the Rey Mysterio–Eddie Guerrero custody storyline that headlined SummerSlam 2005 in a ladder match. No other active wrestler's character work leans this hard on footage of themselves in elementary school.
Returned to the story as Rey's defender against Brock Lesnar in 2019, debuted in-ring against Seth Rollins at SummerSlam on August 23, 2020, and won tag gold with his father in 2021. Earnest, athletic, and — by his own later admission in character — a prop in his father's career.
The Clash at the Castle turn, the prison cosplay after a storyline arrest, the “Oscar” from Rhea Ripley, and a voice designed to be talked over by boos. The joke with teeth: the character built on unearned entitlement has quietly become one of the most decorated young champions on the roster.
From a storyline prop at eight to a two-company champion at 29.
Appears at eight as the child in the Rey Mysterio–Eddie Guerrero custody storyline, culminating in the SummerSlam ladder match.
Debuts against Seth Rollins at SummerSlam on August 23, 2020, at 23 years old, without a developmental run.
Wins the SmackDown Tag Team Championship with Rey at WrestleMania Backlash on May 16 — the first father-son champions in WWE history.
Attacks Edge and Rey the night of Clash at the Castle, September 3, and joins the Judgment Day.
Loses to Rey at WrestleMania 39 on April 1; wins the NXT North American Championship twice — July 18 from Wes Lee and October 3 from Trick Williams — before Dragon Lee ends it at Deadline on December 9.
Wins the IC title in the WrestleMania 41 fatal four-way on April 20; beats AJ Styles at SummerSlam; wins the AAA Mega Championship from El Hijo del Vikingo at Worlds Collide on September 12; loses the IC title to John Cena on November 10 and regains it at Survivor Series on November 29.
Loses the IC title to Penta on March 2 after Finn Balor withholds the hammer; retains the AAA title at Rey de Reyes on March 14; loses the WrestleMania 42 street fight to The Demon on April 19 and the Human Monies on a Pole match to Danhausen at SummerSlam on August 2. Triplemania 34 awaits on September 13.
Family, chosen family, and one demon of his own making.
The defining feud: the son who attacked his father at Clash at the Castle on September 3, 2022 and spent months goading him — “deadbeat dad” promos included — into the WrestleMania 39 match Rey won on April 1, 2023. The angle worked because the family is real; the estrangement is the character.
Stablemate to nemesis across four years. Balor's stray Coup de Grace helped hand Dominik the Intercontinental Championship at WrestleMania 41; Balor's withheld hammer cost him the title against Penta on March 2, 2026; and after the Judgment Day beat Balor down and threw him out, The Demon answered with a table-breaking street fight win at WrestleMania 42 on April 19.
Two title changes on Cena's farewell tour: Cena took the Intercontinental Championship — and the last piece of his Grand Slam — on the November 10, 2025 Raw at Madison Square Garden's expense of Dominik's 204-day reign, and Dominik took it back 19 days later at Survivor Series in San Diego, becoming one of the final men to beat Cena.
The AAA rivalry. Vikingo survived him at Triplemania XXXIII in August 2025 amid AJ Styles' involvement, lost the Mega Championship at Worlds Collide on September 12, and failed to regain it at Rey de Reyes on March 14, 2026. El Grande Americano inherits the challenge at Triplemania 34.
The comedy feud that cost real money: Danhausen stole $100,000 from the Judgment Day, WWE hung the cash above the ring at SummerSlam Night 2, and on August 2, 2026 Danhausen climbed the pole. Very nice, very evil, and — for Dominik — very expensive.
Thin by design — the verified list is short, and nothing is added to pad it.
His first WWE appearance predates his debut by fifteen years — the eight-year-old at the centre of the Rey Mysterio–Eddie Guerrero ladder match storyline.
Playable in the current WWE 2K entries; his first appearance in the series was not verified in this pass and is not claimed.
As Mega Champion he works both companies' television — Worlds Collide, Rey de Reyes, and the September 13, 2026 Triplemania 34 defense — the most prominent WWE-AAA crossover act since the companies' partnership began. No film or scripted role could be verified, so none is listed.
The records, stated the way the sources state them — including the reversed sequence one summary gets wrong.
With Rey Mysterio, WrestleMania Backlash, May 16, 2021 — the record that can only ever be tied, never taken.
April 20 to November 10, 2025, the longer of his two reigns. Fightful marked the 200-day milestone before John Cena ended it on Raw — the win that completed Cena's Grand Slam, making Dominik a footnote in two histories at once.
Since beating El Hijo del Vikingo at Worlds Collide on September 12, 2025 — held across a WWE Intercontinental reign, a WrestleMania loss and a SummerSlam pole match, with the Triplemania 34 defense against El Grande Americano set for September 13, 2026. Day count computed to August 31, 2026.
Survivor Series, November 29, 2025, in San Diego — his hometown — to regain the Intercontinental Championship 19 days after losing it to Cena. Cena's career ended two weeks later against Gunther.
74 days from July 18, 2023 and 67 from October 3, 2023 — per the champions-list table, whose September 30 / October 3 order a circulating biography summary reverses. Only the table's order fits the reign lengths both sources quote.
From September 12, 2025 (Worlds Collide) to March 2, 2026 (the Penta loss), he was Intercontinental Champion and AAA Mega Champion at once — 171 days of double gold, computed from verified endpoints.
Not a measurable record and not published as one — but the “Dirty Dom” reaction is the reason WWE keeps microphones near him, and it is the asset every championship above rests on.
Deliberately absent: a career win-loss total, which no source verifies; the day-precision date of the Triplemania XXXIII loss, which was not re-verified; and social handles, which were not verified in this pass.
Follow, connect and verify.
Yes. As of August 31, 2026 he has held the AAA Mega Championship for 353 days, since beating El Hijo del Vikingo at Worlds Collide in Las Vegas on September 12, 2025. He retained against Vikingo at Rey de Reyes on March 14, 2026, and his next defense is set: El Grande Americano at Triplemania 34, Night Two, at Arena CDMX in Mexico City on September 13, 2026.
Twice. He won the title in the WrestleMania 41 fatal four-way on April 20, 2025 — over Finn Balor, Penta and Bron Breakker — and held it 204 days until John Cena beat him on the November 10, 2025 Raw, completing Cena's Grand Slam. He regained it from Cena at Survivor Series in San Diego on November 29, 2025 and held it 93 more days until Penta beat him on the March 2, 2026 Raw, in the match where Finn Balor refused to pass him the hammer.
A four-year partnership collapsed over a hammer. Balor's stray Coup de Grace helped Dominik win the Intercontinental title at WrestleMania 41; on the March 2, 2026 Raw, Balor stopped JD McDonagh from handing Dominik a hammer, and Dominik lost the title to Penta. In the confrontation that followed, Balor suggested Rey Mysterio had been right about his son — and the Judgment Day beat Balor down and threw him out. Balor answered at WrestleMania 42 on April 19, 2026, reviving The Demon and putting Dominik through a table with the Coup de Grace to win their street fight.
A first-of-its-kind stipulation from SummerSlam 2026, and no, he did not. Danhausen had stolen $100,000 from the Judgment Day, so WWE hung the money above the ring at SummerSlam Night 2 on August 2, 2026, first climb wins. Danhausen retrieved it. The name is Danhausen's own grammar; the money, as of the bell, is Danhausen's own money.
Yes — in 2005, at eight years old, as the child at the centre of the Rey Mysterio–Eddie Guerrero custody storyline, which climaxed in a ladder match at SummerSlam 2005 with his “custody papers” above the ring. His in-ring debut came fifteen years later, against Seth Rollins at SummerSlam on August 23, 2020. He is a third-generation wrestler: grandson of Rey Mysterio Sr., son of Rey Mysterio.
