Nemesis Prime (War for Cybertron Kingdom)

After being mortally wounded in a final battle against Megatron, Optimus Prime was found by the planet-eater Unicron. Unicron demanded Optimus become his servant but Optimus refused. Unicron then convinced Optimus (through unspeakable torture) into becoming the evil scheming Nemesis Prime. Due to resenting his master Nemesis Prime will use his Dead-Matrix to travel anywhere connected to the Dead Universe, including the block world of Minecraft. While forged from his own worst enemy, Nemesis Prime isn't fully against working with his fellow herald Galvatron.
