Character History

Episode:Try The Pie

Billy was a young boy who became depressed when both his parents died in an airplane crash shortly after his eigth birthday. Alone and scared, he took promicin, and soon developed the ability to emit a sonic scream so powerful it could shake buildings and deafen people.

To avoid arrest for taking promicin, now illegal, Billy left his old life behind and was led by Jordan Collier, along with 99 other "promicin-positives", to Evanston, where Billy served as a form of alarm system for the secluded community whenever an intruder was found.

Billy and the rest of the town's population left Evanston under Collier's orders and were led by him to Seattle, and moved to Promise City.
