Crazy Legs was a member of the superhuman gang known as Trash and was, by extension, one of Marvel's many supervillains - facing Power Pack and Luke Cage.
With the rest of Trash, Crazy Legs ran drugs for the Garbage Man. This led to a confrontation with Power Pack and a battle that destroyed a crackhouse.
The Garbage Man beat the team for losing a crackhouse in their battle with Power Pack, then sent them on another mission. When they spotted Power Pack trailing them, Crazy Legs decided to lead them back to Garbage Man's hideout so they could beat them there. Garbage Man was furious, but he and Trash did manage to knock the heroes out. Trash refused Garbage Man's order to kill them, which led to a fight with the Garbage Man. When joined by Power Pack, they managed to take out the Garbage Man and destroy his warehouse. Power Pack tried to convince them to give up crime and Crazy Legs considered it for just a moment, before deciding it would never work.
Working out of Chicago now, the team ran into Luke Cage and fought with him until the people of the neighborhood united and chased the gang away.
Trash approached Troop offering him membership in their gang to help take down Cage. The team went to Rapidfire and arranged to work for him, getting guns with armor piecring rounds that could kill Cage. They set up an ambush, but Troop warned Cage and things got chaotic. Thor Kid ordered Legs to shoot Cage, but he refused. Thor Kid smashed Legs with his hammer. When the building exploded Cage pulled Legs and Blast to safety and they were put onto an ambulance.
