Rocksteady

Rocksteady is a villainous character from the 1987 Teenage Mutant Ninja Turtles cartoon. He is a former human, mutated by Shredder into a humanoid rhinoceros.

Formerly a common criminal thug in New York City, Rocksteady and his partner-in-crime Bebop would be recruited into the Foot Clan by the Shredder and subjected to mutation. Rocksteady's DNA was mutated with that of a rhino, granting him superhuman strength. Though his mutation granted him the strength to battle the Teenage Mutant Ninja Turtles, his complete lack of skill or intelligence prevented him from ever getting the better of them.

Personality
Rocksteady is a brutish, violent thug. However, he is also stupid and utterly incompetent; whatever task the Shredder gives him, he always seems to fail. He is best friends with Bebop and the two of them were always together even before joining the Foot Clan.

Abilities and skills
Rocksteady possesses strength superior to average human beings and has been known to use guns, explosives and blunt-force weaponry. Due to his stupidity, he is not very skilled in combat or any other tasks.
