Vapor

Vapor  is a supervillain made of pure gas and a member of the U-Foes. She is the team's scout.

Appearance
She looks like a female cloud figurine. She has white eyes and brown hair in her human form. Her uniform still remains in tact. She usally has no legs due to her mist form and she usally has the same mist around her.

Personality
She seems to be a feminine type as she asked Cap to give her a "kiss" after penetrating his suit.

Early life
Her early life is unknown but she did go with the other three to space where they get bombarded by cosmic rays to gain superpowers like the Fantastic Four. As a result, she gained the power to be the form of pure gas and can turn human for a brief period of time earning her the name Vapor.

Present Day
At some time later,she and the other U-Foes were captured by S.H.I.E.L.D. and were placed in their specialised cells in the Cube until the Breakout.They remained there by the Leader's influence to help assist him to accomplish his goals.

She was with the other U-Foes attacking the Avengers and S.H.I.E.L.D. agents and Samson in their radiation suits. She attacked Captain America with her suffocating "kiss". Thor later blew her away with his hammer,making her the easiest U-Foe to beat.

She was with the other gamma villains chasing the remaining Avengers and Samson. When the generator exploded,she and the other gamma mutants were caught in it.

Her and the teammates' fates were unknown whether they went into hiding after the second Gamma Dome or were sent to a containment cell.

Powers
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. Flight: She can float and move through air molecules allowing her to fly, at speeds unknown.
 * 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 has a temporary ability to achieve a human state.

Equipment
None. She relies on her pure gas powers to go stealthily and suffocate her opponents. However the Leader once gave her a power enhancing device though she usally dosn't use it.

Role in Ultima
In Ultima, Vapor was freed from Prison 42 with the rest of the U-Foes by Magneto to serve the Acolytes. Vapor enjoys her role as an Acolyte because it allows her to ensare and destroy any unlucky soul that comes across her path of mayhem.
