Meet Casey Jones

The episode begins with Raphael and Michelangelo sparring in the turtle lair. Michelangelo taunted Raphael; Raphael got so mad that he was about to club Mikey with a chair leg. Leonardo stopped the fight and Raph went topside to cool down.

Casey Jones was watching a news report in his apartment about the city's rising crime. Once the report ended, he put on his hockey mask, took his equipment, and left his apartment.

While Raph was clearing his head, he spotted Casey Jones dealing with a couple members of the Purple Dragons. Raph stayed on the sidelines until Casey got too violent. Casey resented the intervention and the two fought one another. Eventually, Casey drove off on his motorcycle, telling Raph to meet him at Central Park.

Back at the lair, the turtles discovered a secret chamber which turns out to be an elevator to an abandoned warehouse. Once Raph returned, he filled the rest of the group in on his encounter with Casey. They decided to fight him again. To prepare, they took the van from their first adventure topside and turned it into the Battle Shell.

On the appointed night, the turtles found Casey on his motorcycle in Central Park. Raph got on the Sewer Cycle and was able to knock Casey of his bike. Raph began to talk some sense into Casey when they were surrounded by Purple Dragons. With the help of the rest of the turtles, they were able to defeat the gang. In the end, they were able to make Casey their ally.
