In what is possibly the most unrevealing character bio ever, Jolt the Volt gets his back-of-the-box debut thanks to S250. Here's what Hasbro wants you to know about Jolt:

Jolt loves to cause trouble. More than one group of Decepticons has watched in confusion as Jolt, all alone, raced around them in circles, taunting them. They're not used to Autobots acting crazy. Little do they know that it really is just an act - part of a plan to lure his enemies in close where he can deliver a crippling blow with his electro-whips.

Somehow, we think his (very) brief appearance in Transformers: Revenge of the Fallen was more revealing than that. Check out the back of box images at TFW!
