Road Hogs

Road Hogs is an Other Strangeness supplement set in the post-apocalyptic After the Bomb future.

Comic
Notably a comic in the back of the supplement features a group of mutant turtles trained in the ninja arts who stand against the Road Hog group of maurauders. There is notable a TMNT poster on the wall, and a mysterious elder who absent-mindedly calls his pupils "Mike".

Eventually when the student turtle ninjas are overpowered by the outlaw hogs, their master leaps into the fray wielding a pair of sai. This strongly indicates that this is an ancient Raphael (still alive far in the future) and that all he clings to is his fond memories of his brother Mike.
