Two decepticon ships flew down, and Amputate became the Nemesis of Walker over time, though Amputate has an obsession with Amputating and Dissection. He first was into Psychology, which is Ironic because Walker calls him a Sadist all the time. He can be seen amputating things in his spare time, or yelling at Decepticons through his Monitor of the first ship that landed on Earth. He is compared to either Shockwave, or Unizarak, though he doesn't know who they are. He is the leader, but not actually the leader.
