Robot cockroaches are very large robots shaped like cockroaches. They appear in the Saturday Morning Adventures comic series.
History[]
The Turtles enter an abandoned building where Screwloose and Wingnut have taken April O'Neil captive. As they set out to free April and spoil whatever plan the bad guys are plotting to do with the machine they've built, a pair of giant robot cockroaches attack. Leonardo faces off with one of the robots and uses his katana to slice off its antenna. Raphael uses the other robot cockroaches' head as a bumper as he bounces one of his sai of its face and up to knock the laser nose off of Screwloose. One of the Turtles, having decapitated a robot cockroach, throws its head at Wingnut and hits him with it. With both of their robot cockroaches destroyed, Screwloose and Wingnut escape back to Planet Flagenon.
