Nemesis Prime (Transformers Armada)

Nemesis Prime is the one shot antagonist of the Transformers: Armada episode Puppet. Nemesis Prime is a dark double of Optimus Prime, used by Sideways against the Autobots and Decepticons.

History
Nemesis Prime was encountered by a party of Autobots and Decepticons on a planet, after they fell into a worm hole that had taken shape due to Unicron's lack of a physical body. Nemesis Prime was a Unicron-created being that was savage and feral in nature, using his Vorpal Saber nearly to destroy several of the Transformers. Nemesis Prime was eventually destroyed by a combined blast from Galvatron using the Requiem Blaster and Optimus Prime using his new Overload power unit. Sideways was seen fleeing the scene, while Nemesis Prime's remains were scattered about the area. The planet immediately began to break down and was destroyed afterwards.
