Alternate Crimson Chins have been shown, from 1936 all the way to 2000, with each different Crimson Chin reflecting the style of that era. There are eight in all: the original Crimson Chin six other past forms and a silver-blue future form. They were wished for by Timmy (in his Cleft guise) to stop the Nega-Chin from taking over Dimmsdale and the world.
This version of the Crimson Chin is the earliest shown. He resembles The Rocketeer, a comic book hero created in the 80s, but resembling the heroes from comic strips of the 30s and 40s. He's also the palest version of the Crimson Chin (probably because he's the original one).
The first redesigning of the Crimson Chin took place during World War 2, in which the Chin was given an appearance more like the soldiers of that era, including dog tags and a "top pot" style helmet. He's a reference to the war oriented comic books, depicting the life and times of soldiers in the battlefield.
During the start of the Cold War, the Crimson Chin was given a more Americanized design, with an American flag for a cape, an a flag with the United States' colors as his logo. A possible reference to the "American spirit" that was given to the comic books and characters, in particular Superman and Captain America.
This version of the Chin has a Hippy look to him, of course referencing the mid 60s era, with Woodstock, the hippy and free love age, and the counterculture comic books.
The 1975 Crimson Chin was a Disco-era based hero, with a big blonde afro. Possibly a reference to the trend of comic books to depict heroes from any medium, including music, like the heroine Dazzler, from Marvel comics.
The 80's Crimson Chin was a heavy weapons superhero. A reference to the ultra violent and dark comic book characters, and the creation of the Image Comics company, and the Rob Liefeld comic book creator, which depicted heroes with pouches, over exaggerated physiques and muscles, and heavy weapons. He was the only cursing Crimson Chin, which he claimed got him cancelled.
The 1995 Chin depicted the rebellious young era, and the birth of the grunge and alternative rock movement, with bands like Nirvana, Sonic Youth, Pearl Jam and others being influences for the young.
Looks identical to the Present-Day Chin. His uniform is plain silver-blue with nothing outstanding. A reference to classic comic book characters like Superman receiving updated costumes and powers in the late 90s.
