Stuart Clarke was born in
East Lansing, Michigan. He was working as an engineer at a company when he created an exo-skeleton suit. His company was bankrupted by recession, and he attempted a bank robbery but battled and was defeated by the
Champions. After being injured in an explosion, Clarke is forced to use a wheelchair, and seeks revenge on the Champions soon after their disbanding. He manages to hypnotize
Iceman and entrap him in one of the Rampage suits, forcing him to battle
Angel and
Spider-Man. Clarke ends up homeless and his suits are stored away in a lab. Over the course of several weeks, Clarke unlocks the control protocols for the suits, allowing him to remotely control the suits and break them out of the lab. Clarke and his friends begin using the suits together and become known as the Recession Raiders. They soon get into a fight with
Wonder Man and
Beast. During the fight, Beast is hit with a brick chimney. Enraged, Wonder Man subdues the Raiders. Beast recovers after a short hospital stay. Wonder Man's enemy Lotus springs Clarke from jail and participates in the creation of the armored team Armed Response. Alongside Splice and Armed Response, Rampage is sent to battle Wonder Man and the group Crazy-Eight. The eight, all personal friends of Wonder Man, manage to summon Wonder Man's help and the villains are defeated. Rampage and his suit become the base for a private security force for Los Angeles. This group is called 'Armed Response' and are secretly corrupt. The Crazy-Eight deliver proof of this to the media, despite Armed Response's attempt to murder them. The force is shut down.
