The Purple Dragons are a gang of three members. They all appear to be Chinese and wreak havoc in New York's Chinatown. They have been threatening businessmen for protection money such as Mr. Murakami, but when he refused to pay they attacked his store. Thanks to Leonardo showing mercy to Fong, they were able to escape. The Dragons later agreed to tell the Turtles location to Xever and Chris Bradford who were looking for them, for a price, but the Turtles already tracked the gang to their hideout in a fortune cookie factory. A fight breaks out, but the Turtles escape when the Foot Clan arrives. Soon the Dragons, Xever, and the Foot kidnap Murakami and threaten to toss him off of a roof. Eventually, Fong, as payback for sparing his life, throws Leo his sword back and they are able to defeat The Foot.
Meanwhile, the Turtles to learn of their plans to help the Shredder destroy the sewers. The Dragons assist Chris Bradford, now Dogpound, in stealing a shipment of chlorosulfonic acid, and they kidnap April for spying on them. While only one member of the Purple Dragons, Fong, participated in the mission, he drove the van that held April until it crashed, when Donatello threw a smoke bomb to distract him. Raphael released spikes to pop the van's tires. Fong was then defeated when April kicked the car door in his face.
Later, the Purple Dragons steal April's cell phone. When the Turtles go to the Dragons' hideout to retrieve the phone, Baxter Stockman's Mousers burrow into the building and steal all the Dragons' loot. Fong uses the distraction to excape with April's phone and takes it to Dogpound. He plans to use it to get information on the Turtles, but they can't unlock it. Meanwhile Tsoi and Sid follow Leo and Raphael into the Mousers' tunnel to find out who stole their stuff. They capture Stockman and bring him to Dogpound, who only spares him so he can hack into April's phone. All three of the Dragons escape after the Turtles attack and the building is overrun with Mousers.
The Purple Dragons once again appear stealing Kraang Tech for Baxter Stockman in order for him to build legs for Fishface. They were first stopped by the Pulverizer, who they soundly beat until the Turtles show up and even the fight.
