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


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 their containment cells.
