The Crimson Chin is a superhero from the comic book series of the same name.
The Chin, as he is sometimes called, is Timmy's favorite superhero. The Crimson Chin has an incredibly big chin (hence his name) and a red outfit. Along with Crash Nebula, the Crimson Chin is very famous throughout Dimmsdale. The Crimson Chin comics were supposedly created by a "forty year old guy that lives with his mom" who was played in live action by Patton Oswalt. He is a parody of Superman.
In reference to his voice actor, the Chin was originally a struggling late-night talk show host (called Chuck Indigo), and gained his powers by being bitten on the chin by a radioactive celebrity, whose reasons of biting him are unknown; since then, he has taken the responsibility of protecting the city of Chincinnati (a spoof on Cincinnati), taking the secret identity of Charles Hampton Indigo (C.H.In, or Ch. In for "Charles Indigo") for the local newspaper the Daily Blabbity. This is an obvious spoof of Spider-Man as Peter Parker is bitten on the hand by a radioactive spider and he works for the Daily Bugle. Also, his secret identity is a spoof of Clark Kent (Superman's alter ego) who worked as a reporter for the Daily Planet.
In some of the adventures involving the Crimson Chin, Timmy enters the comic books he is reading (thanks to Cosmo and Wanda) and takes the role of Cleft the Boy Chin Wonder (a tribute to and parody of Robin), and acts as his sidekick. Wanda and Cosmo, in turn, act as Timmy's two dog sidekicks, Ace the Chin-Hound and Clefto (a tribute to Batman's and Superman's respective super-pets, Ace the Bat-Hound and Krypto). Later Puppy Poof would be added after Poof was born.
The Crimson Chin wears typical uni-colored (in this case, crimson red) spandex outfit, is extremely muscular an kjefnd was turned into a comic world, and ended up running out of metaphors by the end of the episode. He also seems to be supremely intelligent, taunting Short-Fuse to spill out the cage's weakness and break out of it from the outside by provoking Short-Fure and causing the latter to explode in anger. He also doesn't mind if his powers get taken away, as he is positive about normal people and defeated the Nega Chin without it, with the help of other normal 'heroes'; Timmy and his friends.
One of the Crimson Chin's idiosyncrasies is his tendency to use odd metaphors in his inspirational speeches (e.g. "As long as there is one smoldering ember on the barbecue of justice, you can still cook a mighty steak...of VICTORY!"), which is possibly inspired by another superhero parody, The Tick (coincidentally, his costume design is also similar to The Tick) but it's the writers fault. Crimson Chin has also been seen shouting out the names of superhero-portraying actors as a form of exclamation. Two examples being Adam West (who has guest starred on the show in several episodes) and Frank Gorshin. (West and Gorshin have both appeared on the 1966 Batman TV series together, coincidentally.)
