Purple Dragons (Mirage)

The Purple Dragons appear in the 1984 Mirage Comics. The Ninja Turtles fight them in the first issue of the original comic. The Purple Dragons insult the turtles repeatedly, and discover that guns and bats are useless against them. Eventually, the turtles manage to kill them all before the police arrive. The 1984 TMNT comics is the only TMNT version where the Purple Dragons do not work for the Shredder. Though the Teenage Mutant Ninja Turtles & Other Strangeness RPG says that they do.

The Purple Dragons appear again 25 years later in 2009 in Tales of the TMNT #56. Decades ago, the gang's leader, a man named Hunter Mason, who until then was known from the cartoon series from 2003, delivered a brutal beating to a teen-aged Casey Jones, one of the Purple Dragons bitterest enemies, prior to being thrown in jail.
