The Official Transformers Facebook page has posted a promotional image of Terrashock, the Decepticon being introduced in this Saturday's episode of "Robots in Disguise"! Their description follows:
It’s going to take the entire team to stop this stampede. Watch Robots in Disguise this Saturday at 6:30 AM EST on Cartoon Network to see the Bots try to herd their latest foe.
This guy reminds me a lot of Bonecrusher from "Beast Wars" so I'm looking forward to seeing him in action!
