In the third film, Casey (once again portrayed by Elias Koteas) returns 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 feudal Japan. Koteas also appears as an ancestor of Jones named Whit who, like his descendant, ends up helping the Turtles despite anti-heroic tendencies. He also shows a romantic interest in April, as Casey does. It is implied that Casey had gone away for a while, explaining his absence in the second film.
