Rampage (also known as Protoform X) is the awful result of scientific experimentation gone awry. He is a serial killer and cannibal, with an immortal spark that ensures his twisted brand of horror and misery will live on as long as he does (forever, presumably). Rampage detects and draws strength from the emotions of others, literally feeding on the pain and suffering he causes. As an unwilling conscript of the Predacons, he is contemptuous (at best) of the rest of his team, typically bored and uncooperative on missions, and he frequently sneaks off for his own purposes to try to relieve his boredom in the most cruel and horrible ways possible.
Continuity; Primax Cluster (Beast Wars)
Rampage was dragged through a portal by Exitium, who claimed to have saved him from his untimely death by dipping into the timeline and getting him out. Rampage wasn’t that pleased with it, and fled the base.
Session 3 – The first other cybertronians Rampage encountered where Nitro, Riven and Roadkill on their way to Exitium’s base to find Libris. He figured they were hunting him, and opened fire. A short firefight followed, but eventually they spoke to eachother and Rampage decided to help them find their comrade, although it was probably simply a way to do some damage to Exitium.
