Last Friday, an SDCC panel was hosted by Andre Meadows (aka @Blacknerd) and attended by Teenage Mutant Ninja Turtles voice actors Seth Green, Sean Astin, Rob Paulsen, Greg Cipes, Kevin Michael Richardson, Eric Bauza, and Fred Tatasciore along with executive producers Ciro Nieli and Brandon Auman. The panel revealed some key behind the scenes details about the 20 episode pick-up for season five as well as some sneak peeks at season four, such as:
David Tennant (Dr. Who) guest stars as The Fugitoid who was once an alien scientist named Dr. Honeycutt, but after his body was destroyed, his brain was saved and placed into the body of a robot.
Peter Stormare (Fargo) guest stars as Lord Dregg, an arrogant, insectoid crime lord. When the Turtles incur his wrath, he becomes one of their most dangerous enemies.
Michael Dorn (Star Trek) stars as Captain Mozar, the supreme Commander of the Triceraton Fleet. He is a cunning and brutal military commander who answers only to the Triceraton Emperor.
Additional guest stars debuting later this year include: Lance Henriksen (Aliens) as Zog, a scout for the alien Triceraton army; Ron Perlman (Sons of Anarchy) as Armaggon, a vicious, bounty-hunter robo-shark with a taste for turtle; and Zelda Williams (The Legend of Korra) as fan-favorite Mona Lisa, a highly skilled Salamandrian warrior.
