Casey Jones

Casey Jones is a vigilante who is a little nuts. A master martial artist, he uses sports equipment to fight and often wears a hockey mask. Casey's a close human ally of the Turtles and is also a very good friend to them, and he also often acts as a big brother-figure to them. When Jones was young, his father, Herb, owned a shop. A group of Purple Dragon members (lead by a young Hun) burned the shop down, killed his father and took his mother and sister hostage. The badly beaten Casey refused to lay down and take Hun’s blows. He attacked Hun with a knife, stabbing him in the neck. Enraged, Hun had beaten him to within an inch of his life. It seemed that the beating he took from Hun as a teenager resulted in several mental and emotional disorders, explaining his often violent and erratic behavior. New York City, where Jones is from, was overrun by criminals. Enticed by examples from TV, Casey decided to do something about the crime in the streets. After equipping himself with a hockey mask and various sports clubs, he began his vigilante campaign.

He started his career with the Teenage Mutant Ninja Turtles when he ran into Raphael beating up a pair of muggers. When Raphael let them go, he proceeded to "finish them off" but was stopped by Raphael. The two clashed but eventually helped each other take down additional muggers that appeared after their fight. Later, he comes to the aid of the Turtles, Splinter and April O'Neil when they are attacked by the resurrected Shredder at April's home. The seven escape, and retreat to a farmhouse in Northampton, Massachusetts that once belonged to Casey's grandmother. Casey "officially" becomes a part of the Turtles' family around this point, and the farmhouse acts as a second home to them all for some time. At first he and April are not really close, but over time they came closer and closer. In the Mirage series, Casey is extremely violent, even more so than Raphael, but mellows throughout the course of the series. Being a valuable ally to the Turtles, Casey has proven himself in fighting their enemies such as ninjas, mutants, aliens, cyborgs and other supernatural beings.
