Origin

Harley Davis was a hardened street kid in East London by the time she was seventeen. Harley is a walking curse box. She has a feisty attitude that can only be born from the streets of London. She also has a very individual sense of style befitting of a rebellious street-savvy teenager. Her foul mouth earned her the nick name "Motormouth" from the crowd she hang out with.

When Mys-Tech began looking for individuals whose brainwave patterns might be compatible with the M.O.P.E.D (Mind Operated PErsonal Dematerialization) technology their Warheads had stolen, technology that allowed people to teleport across time, space and even into alternate realities, project supervisor Laarson identified Harley as a match. Mys-Tech disguised the technology as pair of shoes, leaving them for Harley to discover, but Mys-Tech's Board, angry at Laarson for previous failures, executed him. Hoping to avoid the same fate by proving chosing Harley was not a mistake, Laarson's assistants activated Harley's M.O.P.E.D unit.

Harley found herself in a futuristic shopping mall, where she purchased a Soni-Muta 500 Unit, a newly developed microchhip that allowed the purchaser to tune into any radio station they want (this will also help her to get her sonic scream in the future). Harley then returns to her own world but is unfortunately captured by Mys-Tech and is sent on a reaping mission, but luckly she escapes and heads for Tokyo, Japan.

Creation
