The episode, "Trans-Dimensional Turtles," will feature an appearance by the 1980s animated versions of the TMNT characters, with the original voice cast reprising their roles.In the episode, the modern Turtles -- Seth Green as Leonardo, Sean Astin as Raphael, Rob Paulsen as Donatello and Greg Cipes as Michelangelo -- are transported to another dimension where they meet their ‘80s alternate-reality counterparts, once more voiced by Cam Clarke, Rob Paulsen (who’s been a part of both series!), Barry Gordon and Townsend Coleman as Leonardo, Raphael, Donatello, and Michelangelo, respectively.All eight Turtles will team up to eliminate both the 1980s animated Krang and the current TMNT villain, Kraang Sub-Prime. The episode will feature different types of animation as well, as the modern Turtles go into their 1980s counterparts' 2D world, before both teams travel back into the modern show’s CG-animated environment.On top of that, look for an appearance into a third world resembling Kevin Eastman’s Mirage Studios Teenage Mutant Ninja Turtles comic book series.Check out a clip, as the two teams travel from the 2D to 3D worlds together.The original voice of Krang, Pat Fraley, will also be heard on the episode, reuniting with the 1980s TMNT cast for the first time since that series. Below is a photo of Cam Clarke, Barry Gordon, Townsend Coleman and Pat Fraley reunited at the voice record session for the episode (Paulsen, unfortunately, was out sick that day).Teenage Mutant Ninja Turtles: “Trans-Dimensional Turtles” airs Sunday, March 27th at 11:00am ET/PT on Nickelodeon.
