Jet, along with Pedro, Judecca Dantes, and Sybil, were part of ROOF's attempt to create artificial Gene Drivers. This experiment only enjoyed limited success. Jet attempted to kill Sybil while she was under the protection of Sheyenne Rainstorm but died while using his ARMs, a Gatling cannon. Though Jet uses the name of one of the Wild Arms 3 character leads, his character model is heavily influenced by Zed from the original Wild Arms game.
