In the 2003 animated series, Jones has a much more important role. He speaks in a Brooklyn accent, voiced by Marc Thompson in English and Tokuyoshi Kawashima in Japanese. This incarnation's personality is on par with Raphael's. Raphael first meets Casey while the vigilante tries to stop a mugging by the Purple Dragons. Seeing a lot of himself in Casey, Raphael tries to reason with him and prevent him from letting his anger get the best of him (Raphael himself had just almost severely injured Michelangelo and was overwhelmed by guilt). Though initially uninterested in what he has to say, Casey eventually bonds with Raphael after he loses to Raph in a bike race and begins listening to his lessons. Casey, Raphael, and the other turtles proceed to team up and defeat a gang of Purple Dragons. From this point on, Casey becomes a valuable ally of the Turtles, and has a closer friendship with Raphael than in any other incarnation.
