their great strength and endurance, and as such, often have to resort to using their surroundings to outwit them rather than fighting them in a straightforward manner. But their attempts at the turtles seem to regularly fail due to their incompetence and goofing behavior, which all leads to them being abused both physically and verbally by Shredder and Krang, and the former even fired them in one episode. In one episode of the series, Bebop was shown to have kept a pet turtle, which got mutated into the evil turtle Slash. In Planet of the Turtleoids, Part 1, Bebop and Rocksteady were responsible for causing a red bull and a mole to be exposed to a mutagen-showering machine at the zoo, transforming them into Groundchuck and Dirtbag, by accidentally setting them free at the same time when Shredder and Krang wanted to mutate a lion and a gorilla (which were freed by the Turtleoid Kerma) to be their latest henchmen. In season eight, Bebop and Rocksteady seemed to have some form of intelligence and talked and joked around less. Rocksteady and Bebop's last appearance is in the season 8 finale Turtle Trek. In that episode, the Turtles destroy the Technodrome's engines, trapping it and its inhabitants in Dimension X for good. While their bosses Krang and Shredder returned in the 10th and final season, Bebop and Rocksteady did not. Their ultimate fate was not explained, although it is assumed that they are still somewhere in Dimension X. Teenage Mutant Ninja Turtles (2003–2009) In the 2003 series episode "Fallen Angel", two characters are seen that are dressed like Bebop and Rocksteady and resemble their pre-mutated appearances. In the episode "Samurai Tourist", the character Gen, also an anthropomorphic rhinoceros, put on human clothing that makes him look almost identical to Rocksteady. Also in that episode, Gen is chased by Kojima, an assassin who happens to be a humanoid warthog. In the Fast Forward episode "Future Shellshock", Michelangelo falls out of a flying truck and onto another vehicle, the driver of which greatly resembles Bebop, only with smaller, more modern sunglasses. Teenage Mutant Ninja Turtles (2012–2017) Bebop and Rocksteady appear in the 2012 incarnation, voiced by J. B. Smoove and Fred Tatasciore, respectively. Rocksteady was first introduced in the series as Ivan Steranko, a Russian arms dealer, and artifact collector with a gold tooth, a diamond right eye, and armed with a pair
