X-Ray (comics)
The U-Foes are a fictional comic book supervillain team appearing in various series published by Marvel Comics. The group consists of four members: Vector, the group's leader who can repel matter telekinetically; Vapor, who can transform into any form of gaseous matter; X-Ray, who can generate and project radiation and fly; and Ironclad, who can transform into any metal form and control his density. They first appeared in Incredible Hulk (1st series) #254 (December 1980). As noted on the first page of that issue, the group's name was inspired by the 1979 Graham Parker song "Waiting for the UFOs".
