Heather and Davis Cameron were a lifeguard and a surfer, respectively, living in Surfers Paradise in Australia. Unbeknownst to them, their father is an underworld crime lord known as Viceroy, and upon his death they were attacked. Together with Storm and Neal Shaara, they managed to defeat their attackers. Heather discovered she was a mutant with the power to manifest whatever was necessary to save the life of someone in danger around her, including her own. Her power enabled her to manifest wings, golden armor, the ability to breathe underwater, and many other less noticeable adaptations. Heather soon joined the splinter team of X-Men, and formed a romance with Thunderbird. During a mission to infiltrate the ship of the intergalactic warlord, Khan, Heather's appearance changes to resemble the alien Shi'ar race, and it was theorized that she and Davis had some Shi'ar heritage. Jean Grey notes that the cranial markings on her head and the crest of feathers she had manifested indicated Heather is of Shi'ar royal ancestry. Also, an entry from Destiny's diary seems to imply that Heather and Davis were "Mothered by War," or Deathbird. The entry shows a picture of Deathbird and some of the X-Treme team. Her brother, unable to see past her new, alien appearance, leaves the team. Lifeguard and Thunderbird travel in search of him.
Months later, Lifeguard and Thunderbird returned to the X-Men, apparently not locating Slipstream. Together with Thunderbird, she joined the X-Corporation. However this only lasted weeks, as there was a synchronized attack on several of the X-Corporation offices after the catastrophic events of M-Day, leading Cyclops to call for the disbanding of all offices. Heather is one of a handful of mutants to have retained her powers in the wake of House of M. Still involved with Thunderbird III, she wasn't active in any X-Men roster, though the 198 Files verified her location as residing at the Xavier Institute for Higher Learning.
Heather later resurfaces after the events of Schism as a member of Cyclops' street team with Boom Boom and Dazzler in San Francisco and Utopia.
Powers and abilities
Heather's mutant power allows her body to react to any threat by transforming or manifesting a power to deal with the situation. In all of her appearances, she has only been shown to use this ability while defending herself and others. It is as yet unknown if she's able to use this ability for her own protection. She has a moderate level of control over this power and has sometimes been able to trigger it at will, although she has not displayed any control over the transformations or powers she manifests. Heather has mostly manifested physical changes such as extra arms, armored skin, wings, and a mermaid tail. However, in her first appearance, she also demonstrated hydrokinesis. The full extent of Lifeguard's abilities have yet to be revealed. In her most recent appearance with the emergence of her inherent Shi'ar genome, she appeared to be locked into her final transformation of gold skin, wings, and claws, still unable to control her powers and possibly unable to transform any further or reverse the change.
