The original comic was heavily influenced by Daredevil, specifically the work of Frank Miller. In the original TMNT origin, the radioactive waste that spills on the turtles comes from a can that falls off a truck. The same waste also hits a teenage boy trying to push a blind man out of the truck's path. This is a direct reference to Daredevil's origin. Also the Turtles' archenemies the Foot Clan is a parody of Daredevil's Hand Clan of ninjas, and Splinter is a parody of Daredevil's mentor Stick.
