Energon Igniters Optimus Prime (Power Series)
Power Series Optimus Prime has a great truck mode. It's a throw back to the classic G1 Optimus flat nosed truck that's also a pleasant little toy. Like all Energon Igniters figures, he's compatible with the gimmick block. Either it can be plugged into his front bumper or in his 'attack' formation.
It's in this mode that his cannons fold out in vehicle mode giving him some firepower. Just a few simple steps and Optimus switches into his robot mode.
Optimus looks more like his movie representation here while forming a very basic robot toy. Articulation is limited to his elbows, which isn't that big of a distraction as it's intentionally a very simple, yet pleasant toy.
