The Incredible Hulk #254

Direct

The U-Foes, a group created by millionaire Simon Utrecht, who, along with three associates, scientist and pilot Mike Steel, life support specialist Ann Darnell, and her brother, fuel propulsion engineer Jimmy Darnell, have rocketed into space and deliberately exposed themselves to cosmic rays to receive powers similar to the Fantastic Four. Crash landing, they emerge unscathed, with new powers, now calling themselves Vector, Ironclad, X-Ray and Vapor. They attack Bruce Banner, who has caused their ship to return prematurely to Earth, which turns him into the Hulk and a battle begins.
