Casey Jones

Arnold "Casey" Jones (sometimes spelled K.C. Jones) is a character of the fictional comic, Teenage Mutant Ninja Turtles. Like the turtles, Casey Jones is a self appointed vigilante in his community, who uses dual baseball bats as well as golf clubs, cricket bats, and hockey sticks to pummel the living daylights out of would-be criminals. He stands at a full 6' 2", and dons a hockey mask (giving him an undeniable visual parallel to Jason Voorhees, albeit of a distinctly different design), shoulder pads, cut-off biking gloves, and carries his array of weapons in a golf bag he slings over his shoulder. Clad in his fighting gear, Casey wanders the streets of Manhattan apprehending hoodlums that terrorize his neighborhood in a fashion not dissimilar to Marvel's Punisher, although without usually employing the latter's deadly force. Casey Jones is a master of stealth, as he has never been caught by the NYPD.

Mirage
Casey first appeared in the Raphael solo issue, "Me, Myself and I". after Raph gets into a fight with Leonardo, he goes out to "cool off." While out, he runs into Casey beating some muggers and proceeds to stop him before the crooks are murdered. Jones and Raph fight several times. Finally, Raph and Casey make peace. In the Mirage series, Casey is extremely violent, even more so than Raphael. He has a step daughter named Shadow Jones and also has a relationship with April O'Neil.

1987 TMNT animated series
In the original TMNT cartoon, Casey Jones is a crazed vigilante who fights crime as horrific as murder, to as petty as littering. He never takes off his mask in the series and his personality is similar to that of Dirty Harry. This Casey does not play as important a role as his comic book counterpart. His most notable line was “When do I get to break something?” Voiced by Pat Fraley.

2003 TMNT animated series
In the newest TMNT cartoon, Jones has a much more important role than in the original show. When he was a young boy, his father’s shop was burned down by Hun and the Purple Dragons. This gave Casey his hate for crime and Hun. It is revealed in one episode that he and the Turtles had met before when they were kids. The Turtles tried to teach him self defense to fight some bullies, but it ended badly. In the show, Casey has a good heart, but is easily tempered and sometimes is usually "thick-headed". He loves motorcycles, is good friends with Raphael, and is romantically involved with April. His main catchphrase is his battle cry “Goongala!”. He speaks in a Brooklyn accent. He is voiced by Marc Thompson.

Feature Films
Casey Jones, played by Elias Koteas, has lead roles in two of the TMNT films. In the first film is a former professional hockey player who had been injured. He turned vigilante and encounters Raphael while attacking some purse-snatchers. Raphael stops Casey from harming the thieves, and Casey turns his aggression on Raphael. The have a playful scuffle and Casey runs off. He later returns to defend the Turtles against an attack by the Foot Clan. He joins the Turtles to assist them against the Shredder and the Foot and ultimately rescues Splinter from the Foot's headquarters and crushes the Shredder in a garbage truck. In third film Casey makes a return at the Turtles request to assist Splinter in watching over the four honor guards that were transported to the present when the Turtles would take their place in the past. Casey will appear in the new movie coming in March, and will be voiced by Chris Evans.

Relationships
Casey Jones's dangerous lifestyle never afforded him the opportunity to marry, though he does have a relationship with April O'Neil and possibly marries her, since Casey’s descendant, Cody Jones, says they are both his great grand parents. Aside from April, Casey Jones has not had another significant other in the 2003 animated series. In the comics, though, after frustrations with April, he took an aimless road trip that led him to Goat Head, Colorado, during which he stopped by a cafe and met Gabrielle. Over time their friendship grew intimate despite the fact that she was pregnant from a previous relationship. He remained by her side and married her, but this happiness would not last for long for Gabrielle would die giving birth to Shadow Jones, subsequently giving Casey custody of her daughter.
