The Crimson Chin is a comic book hero who resides in the city of Chincinnati, protecting his fictional universe from a variety of different metal or body-part-themed villains. The Chin is voiced by Jay Leno of late night comedy fame, who is known for having a large chin in real life.
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 and has a massive, exaggerated chin made to parody uncreative comic book hero designs from the 1960s. The Crimson Chin speaks metaphors in most occasions, he does this heavily when the world 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.)
The Crimson Chin is first introduced in the Oh Yeah! Cartoons short, "Super Humor". The Crimson Chin is only seen as a comic book character, and not an actual living entity.
The Crimson Chin was wished into actual existence in the episode "Chin Up!". After learning he was not real, the Crimson Chin lost all of his confidence and would no longer fight the villains in his comic book world, forcing Timmy to enter the comic book universe himself and inspire the Chin to fight evil again. Timmy is nearly killed by the Bronze Kneecap's knee missile, but is rescued in time by Crimson Chin who thanks Timmy for "saving him from himself". The Chin defeats the Bronze Kneecap with the help of Timmy, who had become his sidekick, Cleft the Boy Chin Wonder.
The Crimson Chin plays a major role in the special "The Big Superhero Wish" when a wish by Timmy Turner turns all the citizens of Dimmsdale into superheroes. The Nega Chin manages to dupe Timmy into unwishing everyone but the villains from having superpowers, stripping the Crimson Chin of them as well. Crimson Chin in his normal form, Charles Hamption Indigo, teamed up with Timmy and his friends to bring down the Nega Chin, The Babyshredder, Bull-E, and Doctor Crocktopus with the help of every day "real superheroes" like a janitor, fire fighter, and milkman. The villains are unwished into their normal forms except for the Nega Chin, who tracks down the Crimson Chin Author in real life to beat him up to try to make sure he wins, but it can be heavily implied this fails since Nega-Chin has yet to show him triumphing over the Chin and Timmy once and for all. Crimson Chin is seen again in the comic "Untold Tales From the Big Superhero Wish!", when the Nega Chin appeared in the real world. He enlists the help of his eight historic Crimson Chin forms, his original form, six subsequent past forms and future form, together they defeated the Nega Chin and the other Super Villains.
In the episode "Lights...Camera...Adam!", the Crimson Chin is the star of a film portrayed by Adam West, who is also the hero Catman. In this episode, the director was purposely making the film bad because he was really the Bronze Kneecap.
West and the Chin met again in "Catman Meets The Crimson Chin", when Catman was introduced into the comic world, and the Crimson Chin was overshadowed by Catman. The Chin then moved away on a bus without even flying, as Timmy stated. Catman later teamed up with Crimson Chin due to his fear of dogs.
The Chin plays a somewhat supporting part in "The Masked Magician". Timmy goes into Chincinnati to get advice from the Chin on being a hero. The Chin still sees Timmy as his sidekick even though Timmy is now a full time superhero known as the Masked Magician. The Chin warns Timmy that being a full time superhero is dangerous because he will soon face an enemy that he unintentionally created. He gives an example with the Bronze Kneecap by grabbing him before Kneecap attacks him. It is explained that the reason why the Bronze Kneecap is the Chin's archnemesis is because the Chin accidentally tripped him during a big Jai Alai competition and won the 1st place gold trophy that Kneecap was trying to win. Furious, Kneecap vowed to end the Chin's career like he ended his. He then became the Bronze Kneecap with the intention of destroying the Chin as revenge. After Kneecap's backstory is explained, the Chin knocks him into jail.
After the birth of Poof, Crimson Chin's appearances dropped off from the show. He appeared in the episode "Chindred Spirits", which is the last Chin-centric episode to date. In this episode, the Crimson Chin was beginning to feel glum over his lack of a love life, and his comic books were reflecting it. Timmy wishes for a girlfriend for the Chin, Golden Locks, but soon her lovey-dovey attitude ruins the comic books even more, so Timmy wishes her to turn into a villain, Hair Razor, but she nearly destroys the Chin who becomes heartbroken, so Timmy purposely puts himself in danger to turn her back to normal. It works, but after saving Timmy, Golden broke up with the Chin, but promised to remain his friend. The Chin still did not lose hope as he still continued attempting to find a girlfriend by the end of the episode.
The Crimson Chin did not appear in Season 7 at all. He eventually returns in the television special "Timmy's Secret Wish!", where he is one of the witnesses called to the stands at Timmy Turner's Fairy Court trial. The Crimson Chin attempts to defend Timmy, but his testimony is twisted by the prosecutor, Foop.
The Crimson Chin is a parody of Superman, among other heroes like Batman, and Spider-Man. Therefore he has several powers like:
Superhuman Strength: The exact magnitude of Crimson Chin strength is unknown. This is because his strength, like his many other powers, has fluctuated over time, however, his strength should effortlessly range into the 100+ tons level at the very least. He can easily defeat a giant robot with little effort.
Invulnerability: Crimson Chin s body is near invulnerable. Gunfire, explosions, falling from extreme heights, extreme temperatures, and extreme pressure have no effect on him.
Superhuman Stamina: He can exert himself for an undefined period of time.
Superhuman Speed: Crimson Chin's superhumanly strong legs allow him to run at speeds that are far beyond the natural physical limits of even the finest human athlete.
Superhuman Agility, and Reflexes: His agility and reflexes are far beyond the natural physical limits of even the finest human athlete.
Superhuman Hearing: He has ears enhanced to hear with amazing clarity, distance, and even frequencies outside normal range. He can hear when someone cries for help, no matter where they are.
Superhuman Leaping Ability: He is able to use his highly developed leg muscles to leap great distances and heights.
Flight: He can fly at great speed.
X-Ray Vision: The ability to see through anything.
Heat Vision: The ability to fire beams of intense heat at a target by looking at it.
Baggage vision: The ability to fire beams to "summon" hisbaggage. He used this ability when Catman was introduced into the comic world, and the Crimson Chin was overshadowed by Catman. The Chin then moved away on a bus without even flying, as Timmy stated
Healing Factor: In the extreme event that Crimson Chin is harmed, either by an oponent matching his own strength or other occurrence, he has been shown to have the ability to heal almost instantaneously from any wound,
Power Pupils (Power Granting): He can give superpowers to others, like he did with Timmy.
Self-Awareness: As a result of Timmy's wish, he is aware that he is fictional and he is a comic book character, breaking the fourth wall.
