2003 animated series
Sunny is a member of the Purple Dragon street gang with a long braid, and appears in the first and third seasons of the 2003 series. He appeared in several adventures of the Turtles as a lesser antagonist. In "Things Change, he and other members of the Purple Dragons fought the Turtles but were defeated by them.
In the episode "Fallen Angel" he tried to fight Angel in her initiation match but was knocked out by Casey Jones. He later fought the two Purple Dragon initiates (Leo & Raphael) in the Purple Dragon cage match. Sunny was defeated by them in the cage match.
While he debuted in the series' very first episode, his name wasn't given until his appearance, in "The Christmas Aliens", where he and Spike and Two Ton hijack a truck full of “Lil’ Orphan Alien” dolls that are supposed to go to an orphanage, but are stopped by Michelangelo. Sunny did however manage to call for backup before Mike threw him from the truck. He appeared to have been the leader of the group. His whereabouts after the reorganization of the Purple Dragons as a result of the disappearance of the Utrom Shredder is unknown.
