Casey Jones (2012 TV series)

Casey Jones is a teenaged human vigilante who hunts down mutants and criminals.

History
Not much is known about Casey Jones, but he clearly knows about the existence of mutants. He has created his own weapons, which he use against his enemies; mutants and criminals. It's hinted that he has been in the sewers and might even have his own lair set up there. In the online comic, he had spray painted "Jones is Everywhere" with his iconic hockey mask next to it, possibly indicating that he goes down there occasionally. In his debut-episode Mutagen Man Unleashed, he encounters April in the hallway where he tells her that she's his tutor. Even though he proved he would be difficult to work with, he says he's willing to cooperate if it means staying on the hockey team. April agrees to help him and decides to tutor him that night in the park.

When they start their session, Casey tells April that he's not interested in trigonometry and wants to be a hockey player or a bounty hunter once he graduates. Despite everything April had witnessed that day, he surprises her by asking who wants to live a normal life. When April sighs a bit, Casey shows empathy. He then notices a smudge on her face and wipes it off, which shocks Donatello, who is watching them from a rooftop.

On their way back home, Mutagen Man shows up and tries to approach April. Casey steps in front of her and manages to get a couple of hits in. However, he and April barely fend him off, but they are able to shake him off and escape unharmed. They make their way back to April's apartment while watching out for anymore mutants. They make plans for their next tutoring session just as Mutagen Man prepares to go after April. Casey almost heads towards the alley where the turtles are fighting Mutagen Man when April redirects him to the other way.

In Target: April O'Neil, he meets April in the hockey ring where they strike up a conversation. He asks her why she doesn't hang out with other people, which results in her telling him that she and her friends "are fighting". He relates her situation to his friendship with his best friend ending after he accidentally injured him during a hockey game. Even though both say that Casey didn't mean to hurt him, he repeats that it was something that was beyond his control. Just then, when Casey goes to change, the robot Foot Soldiers attack April. He shows up and starts fighting them off while telling April to leave him. Despite his wishes, April helps him fight the soldiers and leads a few away. After the turtles defeat Karai and her robots, April returns to the ring to find Casey unharmed.

Personality
Casey seems to be very arrogant, a bit flirty(or at least around April), very inattentive to his school work and thinks highly of himself. Even with his first encounter with April, he managed to show how involved he is with himself and thinks little of others. But he admits that he does need a tutor as he wishes to stay on the hockey team. And while he tend aggravate April a bit during their tutor session, he tried in his own way to be friendly and get her to enjoy herself with something besides books. He also shows a sense of empathy when she shows to be exhausted from today and reaches out to wipe off a smudge off her face.

During their encounter with Mutagen Man, Casey became protective April and tried his best to watch out for her. He was also very impressed by how April fights and when he asks if encounters like with Mutagen Man happen often. When she answers too often, the idea excites him.
