Purple Dragon is a public criminal gang that is operating right in the city. They blatantly cause riots and even rob, which causes people to live in fear. But soon, when the team of four turtles: Michelangelo, Donatello, Raphael, and Leonardo appeared, their activities were prevented that they could not achieve their wanted results. Sometime later, Purple Dragon teamed up with Stockman to create destruction robots, caused a series of issues such as kidnapping people to extort money, and revenge against green heroes by burning down the houses of them. The leader Michelangelo became very angry and led his team members to destroy Stockman’s Baxter factory. It was this event that led to Stockman cooperating with The Shredder – the leader of the Foot Clan, to implement the plan of creating mutant creatures and kidnap Raphael as well.
