What's red, blue, and cool all over? None other than the unstoppable ally! Convert this OPTIMUS PRIME robot-to-vehicle figure from AUTOBOT robot warrior to Earth truck vehicle mode and back again. Simply roll the truck forward to activate electronic revving engine sounds and the auto-spin conversion technology. Watch as the vehicle's cab spins and changes into the robot's upper body! A twist here and a turn there and you've completed the change from vehicle to robot mode. Place the Ultra-Axe in the robot's hand and trigger the automatic pop-out "plasma blade". Stage your own DECEPTICON showdown with punching and axe combat action. Amaze onlookers with electronic speech, sirens, lights, and battle and conversion sounds -- his mouth even moves when talks, making him quite believable when he states, "My name is OPTIMUS PRIME!" Includes 2 "AAA" batteries.
