Krang is a villain created for the original animated Teenage Mutant Ninja Turtles TV series. Here, we get to see his Android Body in action as Kraang and Krang take on the four sewer dwelling brothers. Although, very little is known about how he fits into the story. An official synopsis for the sequel has yet to be released, although many fans were pleased that fan-favorite characters Casey Jones, Bebop and Rocksteady are finally making their first-ever big screen appearance.

Dave Green directs from a script by André Nemec and Josh Appelbaum. The screenwriters also wrote last year's Teenage Mutant Ninja Turtles, which took in $485 million worldwide from a $125 million budget.Teenage Mutant Ninja Turtles 2 is slated for release on June 3, putting it up against Universal Pictures' Top Secret Untitled Lonely Island Movie. It's possible that Teenage Mutant Ninja Turtles 2 could put up even bigger numbers than its predecessor this coming summer, but we'll have to wait and see.
