Vapor's history prior to being recruited as a technical specialist for his space mission by Simon Utrecht has yet to be revealed. She, along with her brother James, was among the small group led by Utrecht to simulate using gamma radiation to achieve superhuman attributes, and has remained with the U-Foes ever since.

Powers and Abilities Edit

Vapor's body has been bombarded with cosmic rays far greater then that of the Invisible Woman, since then her brother X-Ray has once more bathed her in cosmic

rays so as to achieve better control over her gas-like form.

  • Gaseous Form: Vapor's body is that of living gas(es). She is mostly invulnerable to physical harm, although she can still be harmed by unconventional attacks.
    • Gaseous Form Manipulation: Vapor is capable of transforming her body into any type of naturally occurring gas, either a pure elements or with complex compounds including mono-molecular mists. She has once accidentally melted the skin of her teammate Ironclad. She can only achieve a human state again temporarily.
    • Flight: She can float and move through air molecules allowing her to fly, at speeds unknown.
