Heidi Sladkin, was a young punk rocker, with spiked brown hair. She assumed the name Riot, because she was a Riot Girl. While in a New York airport, she suddenly began to barf continuously. Shortly after that, she gained the ability to see through the Skrull disguises. Her new abilities startled her. The Skrulls immediately attempted to kill her when they realized she could see their real forms. They pursued her, but she was rescued by
Ryder and the others, when they attacked the Skrulls. Riot joined the battle, first becoming "hardbody." She later took the form of a giant alien looking insectoid creature. Ryder, Riot and the others later agreed on the name of the
Skrull Kill Krew.
