Naked Mideon- That gimmick and Mideon was just a waste altogether
The Spirit Squad- There were a lot of talented wrestlers in the squad like Dysktra and Ziggler, but no one knew that because this gimmick was so terrible.
The Radicals- Chris Benoit and Eddie Guerrero were the only benefactors of the group. Dean Malenko turned into the ladies man and Perry Saturn had an affair with a mop.
Suicide- TNA's suicide gimmick was a failed character from a failed video game that no one cared about.
Cody Deaner- We will never know how talented Chris Grey is because of this low rent gimmick. Instead of being a southern man's man Deaner just turned out to be a blue collar comedy tour joke poking fun at southern people and people that live in trailer parks.
Shark Boy- The man is cheered in the impact zone, but even when he was doing impressions of Steve Austin no one took Shark Boy serious. How could you with that name?
Giant Gonzalez- The man was the tallest athlete to compete for the WWE. He was 7'6 and billed as an 8 foot giant. Even the Undertaker couldn't build this man up with his limited ring ability and his Sasquatch naked man tights.
The Yettie- A man dressed as a hairy mummy that appeared on Monday Night Nitro against NWO. Horrible.
Gillberg- a cheap imitation of Goldberg that was funny the first time, but was a cheap joke that went on too long afterward. At least the man won the light heavyweight title.
The Ding Dongs- Jim Ross probably still has nightmares of this team. Ding and Dong wore orange suits and masks. Every time they wrestled they would ring a large bell at ringside.
TL Hopper- A plumber that eats chocolate bars in the pool that look like turds. Awesome.
Eugene- Nick Dinsmore never had a chance. A mentally challenged man that imitates wrestlers. The only reason people cheered for him because they felt sorry for him.
Charlie Haas- A gifted athlete that was reduced to being a low rate wrestling impersonator.
Lance Storm- Another solid performer that was limited by his " Can I be serious for a moment" gimmick.
Mike Awesome as that 70's Guy- One of the best big man performers around wasted as the "Fat Chick Thriller" a guy that wore leisure suits and loved large women.
The Shockmaster- The gimmick failed before it ever got off the ground. Later The Shockmaster was turned into a goofy klutz known as Uncle Elmer.
The KISS Demon- KISS performing live on Nitro was one of the lowest rated shows in history. The former baseball player turned into the KISS Demon didn't help matters.
The Gobbledy Gooker- Another brilliant invention from Vince and the WWE machine. People were waiting weeks for the big surprise at the first Survivor Series. What the got was a big dancing joke of a guy in a turkey costume.
Aldo Montoya- Portuguese Man O War- Just saying the name is forgettable. Thankfully Justin Credible had success else where.
The Patriot- This red white and blue freak was pushed hard into the main event against the anti American pro Canadian WWF champion Bret Hart. Too bad the audience give a damn about the Patriot to notice.
Johnny B Badd- Marc Mero as a cross dressing Little Richard impersonator.
Se7en- Dustin Runnels dressed in white with a black hate and jacked like the Undertaker.
The Red Rooster- Poor Terry Taylor was the butt of many jokes with this horrible gimmick. The man would crow during his interviews and actually had a spiked red hair.
The Blue Blazer- One of the worst gimmicks of all time that started when Owen Hart first came into WWF and ended in his tragic death. If WWE and Owen Hart never agreed to this gimmick maybe he would still be alive today.
Other Honorable mentions- Billy and Chuck, Max Moon, Rhythm and Blues, Outback Jack, The Goon, Skinner, The Sultan, Isaac Yankem, The New Rockers, Glacier, Renegade, Van Hammer, Man Mountain Rock, Vinnie Vegas, Oz, Dean Douglas, Disco Inferno, Adam Bomb, Bastian Booger, Akeem, The Beserker, Robocop.
