List of characters in Celebrity Deathmatch

This is the character list for regular characters that appear on Celebrity Deathmatch.

Present main characters

* Johnny Gomez "(Maurice Schlafer (1998-2002), Jim Thornton (2006-present))": Co-commentator on "Celebrity Deathmatch", Johnny is the more professional one, and a loyal friend of Nick's despite his constant blunders. Johnny's hair has noticeably changed from black to brown in the new season. Judging by a comment made by interviewer Tally Wong during one episode, he may be wearing a hairpiece."
* Nick Diamond "(Len Maxwell (1998-2002), Chris Edgerly (2006-present))": Johnny's co-host, a perceived alcoholic and divorced father of one, he is always screwing up. He harbors an intense hatred for interviewer Debbie Matenopoulos and has also participated in and won several matches by himself.
* Mills Lane "(himself (1998-2002), Chris Edgerly (2006-present))": The official referee of the Deathmatch ring; he always starts matches by saying "Let's get it on!" and shows that this is one ref you can't knock down with one hit. Another catch phrase is when there is a disputable move by either fighter, like using foreign objects, and he says "I'll allow it!", implying that just about anything is legal in the ring. Due to his suffering a stroke in 2002, the real Mills no longer voices his own character.

Minor regular characters

* "Stone Cold" Steve Austin "(himself)": World Wrestling Entertainment (WWE) Wrestler and guest commentator on "Celebrity Deathmatch". Also the scientist, doctor and weapons expert on the show. He also fought and won a match against Vince McMahon (voiced by McMahon himself, and whom Austin would actually wrestle with on several WWF events in real life). Apparently, Austin has not shown up in the newer seasons, for Nick has once stated that he was too expensive to bring back.
* Stacey Cornbred, "(Mz. L)": The first interviewer on "Celebrity Deathmatch", Stacey maintained a more professional air than Debbie. She kept her interviewing job until her untimely demise from spontaneous human combustion. Though she had exploded, she briefly returned in a Halloween episode as a zombie to challenge Debbie in the ring only to be soundly (and messily) defeated.
* Debbie Matenopoulos (herself): The interviewer that succeeded Stacy Corbred after her untimely death. She hates Nick and doesn’t prepare for any interviews, usually just asking whatever she feels like. She often believes herself to be smarter than she really is. Left the show late in the last season on maternity leave.
* Tally Wong "(Masasa Moyo)": The new interviewer from Season 5 onward. Before most of the matches, she interviews the combatants in a segment called 'Tally's Korner'. Tally is very self-centered, and usually spends most of her interviews insulting the celebrities rather than asking questions. She often makes rude remarks about the celebrities, and at times Nick and Johnny, during matches. Whenever Nick or Johnny gets mad at her for it, she taunts them by daring them to "bring back Stacey Cornbred." Tally harbors an intense hatred toward Johnny Gomez. Ironically though, this was the inverse in the previous show with Nick Diamond hating on Debbie Matenoupolis.

Minor characters

* Marv Albert "(Himself)": CDM's first guest commentator. He only appeared in the pilot episode before being replaced with Stacey Cornbred. Best recognized for wasting one show watching the slow-motion replay of Pamela Anderson's implant-laden breasts jiggle repeatedly.
* The Masked Man "(Chris Edgerly)": Appearing in the first two episodes of the 2006 season, the true identity of the Masked Man is shrouded in mystery. In both his appearances, the Masked Man has appeared in a seemingly one-sided match and attacked the winning celebrity. Even though in both matches he has appeared in, he has managed to render his opponent completely helpless, he always runs away after suffering a single blow. He is quite obviously supposed to be Michael Jackson, as his pale skin, high-pitched voice, eccentric dance moves, and habit of seductively leering towards small boys are all dead giveaways. Despite this, no one can seem to identify who he really is.
* Don King "(Kerry Williams)": Don King appears several times in the first season. He is killed several times as a running gag, a likely reference to the character Kenny McCormick of South Park. Later on in the series during the episode "High-Tech Fighting", Don King fights against Donald Trump, only to lose and die for good.
* The Popcorn Vendor "(voice unknown)": The name pretty much sums up his job. Basically, he's something of a running gag, as he is usually among the first victims in the audience when a Deathmatch gets too brutal to stay in the ring. Since his second season appearance, the vendor has been burned, chopped up, and even possessed by a demon at various points, only to come back again healthy in his next appearance.
* Nicky Diamond Jr., "(Brendan Muller)": Nick's son, who appeared in several episodes. In one episode he was possessed by a demon called "Captain Doody," but was delivered when The Undertaker executed a Tombstone Piledriver on the possessed Nicky during their bout, causing the demon to leave Nicky and enter the hapless popcorn salesman.
* Zatar the Alien "(Eric Fogel"): Zatar The Alien is a green, one eyed alien who has a habit of wagging his tail. He appeared in two episodes. In the "37th Annual Sci-Fi Night", he killed Celine Dion (after possessing her), Keith Flint, Mark Hamill and Peter Mayhew. After killing the latter two, an enraged Nick Diamond comes down to the ring and defeats Zatar by ripping his brain out through his eye. Later, at the end of the episode "Deathcon 2001", he destroyed the arena with an Independence Day-style laser blast from his spaceship.
* Marilyn Manson "(himself and an impersonator)": The controversial rockstar is the undisputed champion of Celebrity Deathmatch. He was featured on the original Celebrity Deathmatch pilot where he fought and defeated Charles Manson. He has also defeated Garth Brooks and Ricky Martin, while killing off Hanson and the Spice Girls in a match he did not participate in. Manson provided his voice for two of the episodes he was featured in.
* The Machine "(Eric Fogel)": The Machine is a former kitchen robot that had been reprogrammed by "Stone Cold" Steve Austin to fight the popular rock band Rage Against the Machine during episode 11 (In The Head Of Nicky Jr.) of the third season.
* Betty-Sue Olsen "(voice unknown)": Betty-Sue Olsen is the "third Olsen twin" who had been locked in the attic and fed fish heads because she was not as pretty as Mary-Kate and Ashley. During the fight between the two Olsen twins, Betty-Sue breaks out of her cage, goes down to the ring, and tears her sisters apart, winning the match. Later that night, she kills Jennifer Love Hewitt and chews off Scott Wolf's face after they defeat Reese Witherspoon and Ryan Phillippe.

The Freaks

* Cousin Grimm "(voice unknown)": Cousin Grimm is made from the combination of the DNA of Bill Clinton, Bigfoot and Roseanne Barr. He fought Pierce McCrack in the episode "Freak Fights" and won by ripping out his spine. He fought Potato Khan in "Deathcon 2001" and he sliced Potato into several small Khans which he ate. However, the pieces of Khan then got into Grimm's brain, and when trying to get them out by bashing his head with a club, Grimm bashed his own head to pieces.
* Pierce McCrack "(voice unknown)": He is made from the combination of the DNA of Dennis Rodman, Trent Reznor and Keith Flint. He only fought once, against Cousin Grimm in the episode "Freak Fights". Cousin Grimm killed him by ripping out his spine and impaling it through his torso.
* Beni Trauma "(voice unknown)": Beni Trauma is one of the freaks of Stone Cold, he is made from the DNA of chef Emeril Lagasse and action star Jackie Chan. He fought once against Potato Khan in episode "Battle Of The Heavy Metal Maniacs". He was about to defeat Khan by cooking him but he used a rare special sauce which made Khan sprout tentacles, after which Khan ripped off Beni's head. For the rest of the episode Khan cooked parts of Beni's body and gave them to a kid in the audience who was having a birthday party so he can eat them.
* Potato Khan "(voice unknown)": Potato Kahn is made from the combination of the DNA of Joe Pesci, Genghis Khan and a potato, due to "Stone Cold" accidently dropping a french fry into Khan's stasis tube. He fought against Beni Trauma in the episode "Battle Of The Heavy Metal Maniacs" and won by sprouting some tentacles and ripping Beni's head off. In the episode "Deathcon 2001" he fought Cousin Grimm, who turned him into several small Potato Khans with a cheese grater and ate him. The small Potato Khans then got in Grimm's brain and Grimm broke his head apart in an attempt to get them out of his head. He is also seen in episode "Blink 182 vs. 98 Degrees", chained to the wall of the Celebrity Deathmatch basement.
