Davis Cameron and his sister
Heather are from
Surfers Paradise in
Australia, where they respectively work as a surfer and lifeguard. They do not know that their father is the underworld crime lord Viceroy. Upon their father's death, the two are attacked. Davis is informed by
Sage that although he was never meant to be a mutant and that his latent mutant gene was supposed to be passed down to his children, his mutant power may be helpful to her. He agrees to let Sage activate his powers, gaining a teleportational ability in the form of the "warp wave". Together with
Storm and
Thunderbird, Davis and Heather fend off their attackers. Following these events, both siblings join Storm's team of X-Men. Later, when infiltrating the ship of the intergalactic warlord Khan, Heather develops a more avian look, leading to speculation that the two are related to the
Shi'ar (an alien species with avian traits). Slipstream is among the mutants who lost their powers as a result of
M-Day. ==Powers and abilities==
