Hulk Wiki

The U-Foes

The U-Foes are a group of enemies that appear in The Incredible Hulk video game and various Marvel comics like Marvel Adventures 6: The Avengers. They are usually depicted as enemies of the Hulk. 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 has a metallic body and can control his density.



Real Name: Simon Utrecht

Simon is able to use the distinct ability of telekinesis. Simon is also able to concentrate telekinetic blasts which are able to harm even the Hulk. In The Incredible Hulk, Vector fights by controlling a large mass of rocks to use as a shield. Hulk would need to break this wall while being attacked by him in order to hit him.


Real Name: Ann Darnell

Ann is able to genetically turn her body into any type of gas. She would usually use a very poisonous gas like methane. Sadly, Ann is only able to stay in her human form for a very short period of time. In The Incredible Hulk, Vapor attacks by turning into different kinds of gases and attacking the Hulk, either draining his health or rage.


Real Name: Jimmy Darnell

Jimmy is a being of pure energy who can fly and fire blasts of radiation at his enemies. In The Incredible Hulk, X-Ray attacks by firing charges of energy at Hulk. Hulk cannot get near him until X-Ray is drained.


Real Name: Michael Steel

Steel has been permanently transformed into a metallic monster. He is extremely strong, durable and also is able to manipulate his weight, as well as fly. Steel's former Ironclad transformation was all jagged, but a mishap with his weight altering powers had forced him down, bending the jagged steel parts into smooth, human-like skin.

In other media[]

  • The U-Foes appear in Avengers: Ultron Revolution, with Vector voiced by Glenn Steimbaum, Vapor voiced by Catherine Taber, X-Ray voiced by Jeremy Kent Jackson, and Ironclad voiced by Eric Ladin. Backed by HYDRA, four scientists ride a spaceship into a cosmic gamma storm. In their self-titled episode, their spaceship threatens to crash into Vista Verde, but the Hulk ends up redirecting it. Upon emerging from the spaceship, the scientists discover their powers and take the U-Foes name because their spaceship resembled a UFO. Unwittingly mentioning HYDRA's involvement up front, the Hulk ends up attacking them, only to be subdued. Heading to HYDRA's base, the HYDRA agents are informed by the U-Foes that they will lead HYDRA as the Avengers attack. The U-Foes fight while the HYDRA Agents download everything top secret before escaping. Later on, the U-Foes and HYDRA infiltrate an abandoned S.H.I.E.L.D. base and steal an old-fashioned Helicarrier. While preventing the crashlanding Helicarrier from heading into a nuclear power plant, the Avengers trick the U-Foes into going into a room where they were subdued by knockout gas.
