Voyager class Optimus Prime (without trailer) comes with an all new mold. He comes with a cool heat shield in his body sculpt and solar panels on some parts of his body and gas tanks. Those solar panels are translucent.
He was equipped with a MechTech weapon – the Ion Blaster that transforms into a Battle Cannon for extra damage to the enemies. His weapons are able to lock into place while deployed in alternate mode vice versa..
