Transformers Animated: Bumper Battlers feature "bump-and-transform" action - hitting the front bumper causes the toy to change into robot mode, and pressing the toy's sigil activates sound effects and speech gimmicks. Transformers Animated Bumper Battler Optimus Prime seems to be the equivalent of one of the Cyber Slammers from the Movie 2007 line-up. Sporting a predominantly red, blue and silver color scheme, he appears to support articulation at the elbows. A well-trained natural leader, this comparatively untested version of Optimus Prime swells wistfully on the accounts of old battles until he finally receives his first assignment: Pitted against Megatron and the other Decepticons, Prime leads the Autobots in a venture to keep the All Spark out of the tyrannical grasp of Megatron.
