Description from original post (created 2013-01-01 20:13):
Nemesis Prime is a monstrous Transformer sent to kill Autobot and Decepticon alike. It scanned the minds of the Transformers and took the form of Optimus Prime, as he was the most powerful and respected in all their minds. As a duplicate of Optimus Prime, Nemesis has all of Prime's strength and power, in addition to his own ability to reconstruct himself. Nemesis Prime wields the Vorpal Saber, a twisted clone of the Star Saber, and has a Mini-Con partner named Run-Over.
