The Purple Dragons are a street gang led by Hun that often fight the Ninja Turtles and major antagonists in the Teenage Mutant Ninja Turtles comics, animated TV series, and video games. The gang as a whole is one of the the most dangerous organzations the Turtles have faced.
They mostly commit robberies and threaten people. They're one of the most dangerous street gangs in all of New York City (if not the most dangerous), and they work for the Shredder on most occasions. Because of this, they sometimes also carry out acts of assassination and even terrorism.
In MNT Gaiden, Purple Dragons are a favorite target of vigilante fights involving Raphael Hamato, Casey Jones and Shadow Jones, the latter two fighting the Purple Dragons while masked.
According to Chapter 13: Back into the Shadows, the renegade NYC Foot Clan leader Eikichi Gotoh holds the Purple Dragons in contempt as an organization, because Purple Dragon members only follow their own individual desires, whereas the NYC Foot Clan establishes a common group goal that is served by all its members as a whole. An unnamed gang that is similar to Purple Dragons was featured in 1987 TV Series. They were led by Bebop & Rocksteady.
In the 2012 series, the Purple Dragons are a Chinese American gang that, up until Casey Jones vs TheUnderworld, consisted of 3 members, Fong, the unofficial leader who occasionally wields a butcher knife, Sid, the muscle who occasionally wields an axe and Tsoi, a mustached middle-man who occasionally wields a sledgehammer. The Purple Dragons mostly commit petty street-level crimes, such as mugging citizens, robbing banks, forcing business owners to pay protection money and doing lackey work for bigger crime lords (Shredder and, at one point, Ho Chan). Unlike in other versions, the Purple Dragons are portrayed as comic relief villains who couldn't put up a fight with the teenage Casey Jones, much less the turtles; thus, proving that they only serve as threats towards those who can't defend themselves.
Despite their numerous defeats and failures, the Dragons are a respected and feared gang who commit crimes in broad daylight unopposed. In Casey Jones vs The Underworld, the Dragons become a much bigger threat when they are now lead by Hun, who, unlike in the 2003 version, is a quick and nimble martial arts master and a clear homage to Bruce Lee. With Hun still in tow, the Purple Dragons are now seen as a much bigger threat who now can easily take on the likes of Casey Jones, Michelangelo and Karai with her friend Shinigami at the same time. Despite this impressive feat, they end up becoming comic relief again during their last few appearances, such as when April easily defeated them when her powers were out of control.
In the Rise Of the Teenage Mutant Ninja Turtles
