Teenage Mutant Ninja Turtles 2 is a thing — this much was already known. But we had no idea that Michael Bay and Paramount Pictures had plans to bring two of the most infamous villains in the franchise to life in the live-action sequel.
If you don't already know who we have in mind, we're talking about Bebop and Rocksteady. Bebop is a mutated warthog, and Rocksteady is a mutated rhinoceros. Both bad guys made their debut in the TMNT cartoon back in 1987 — and it didn't take long for them to become the favorite villains of many fans.
These creatures were created by Shredder to aid him in taking down the Turtles, among other things. After the mutation transformation process was complete, they came out looking pretty badass. Though they were stronger — they were certainly no smarter, which is why they never managed to best the Turtles and tend to make Shredder angry.
