Casey Jones
At the hockey rink, Casey's coach berates him again for body checking another player. His cousin, Sid then calls him a benchwarmer, causing Casey to hit him in the face with his hockey stick out of anger. The coach then kicks Casey off of the team. On his way home, Casey tosses all of his hockey stuff, except for his stick, away and then spots a boy spray-painting graffiti on his building. Casey chases the boy away and then heads to his house and asks his mom if he can stay with her for a while. When she accepts, Casey tries to fix the sink, but he ends up breaking it, causing it to rain in the kitchen.
That night, while cleaning the graffiti off of his building, the graffiti boy and his gang, The Purple Dragons, arrive and brutally beat him. Casey then crawls back into his house and falls asleep on the kitchen floor after he puts the tooth they knocked out back into his head. When he wakes up, his mom berates him for constantly getting into trouble. Casey tells her he got jumped, causing her to say that she's decided to sell the building and head back to Northampton. Casey promises to fix everything.
Over the next week, Casey starts training by lifting weights, jogging, hitting a punching bag, and smashing stuff at the local dump with his hockey stick while April O'Neil does a news report on the Lower East Side, a part of the city ruled by the Purple Dragons and other street gangs. After he finishes training, Casey makes himself a new hockey mask. That night, when Casey spots the Purple Dragons mugging a woman, he viciously attacks them until all of them except one are knocked unconscious. He beats the last one unconscious with a golf club and heads out into the city, where he spots two thugs breaking into a car. He swoops down and beats one of the thugs unconscious and then breaks the other's legs, but before he can finish him off, a man in a trench coat takes his bat. Casey takes out another weapon to finish the goon off when the coated man stops him again. Casey attacks the interloper, who is revealed to be a mutant turtle named Michelangelo. The two then fight, with Michelangelo gaining the upper hand. Michelangelo then lectures him for brutally beating thugs to death.
Mikey then tries to leave, when he's suddenly attacked by the Foot Clan. Casey and Mikey then team up to fight the ninjas, but when one of them scratches his mask, Casey takes out a sledgehammer and uses it to defeat the rest of the ninjas. Casey starts beating the last ninja standing when his mask comes off, revealing him to be Sid. Casey reveals himself to Sid, who tells him that they're only after Mikey, but Casey refuses to leave Mikey behind. Suddenly, Krang and more Foot ninjas arrive and surround Mikey and Casey. Sid then knocks Casey unconscious with Casey's own cricket bat. Mikey knocks Sid out and fights Krang and the ninjas off. Mikey takes Casey back to his lair in the sewers, where he's introduced to Leonardo, Raphael, and Donatello. April reports about Casey saving the woman.
Some time later, some goons steal a pizza from a pizza delivery boy and take it to an alley. One of the goons suggests they move somewhere else because he's scared of running into Casey Jones, but another goon assures him that Casey is just a myth. Casey shows up in some new armor and knocks the goons unconscious. Casey notices the strange toppings on the pizza and takes it back to the sewer lair where he gives it to the turtles. Casey assures the turtles that he went easy on the thugs.
