    No recent wiki edits to this page.


    Jimmy Darnell was a systems propulsion engineer before he gained his superhuman powers. He was aboard the spaceship with Simon Utrecht, Michael Steel and his sister Ann Darnell when they got bombarded with heavy doses of cosmic rays. All four members got their powers and became the U-Foes. X-Ray and the rest of the U-Foes blamed Bruce Banner for interfering with the flight program and it brought back the crew before they could absorb even more cosmic rays which would make them more powerful. The U-Foes attacked Banner and Ironclad held him in his grip while X-Ray radiated Banner until he passed out. Suddenly Banner transformed into the Hulk and broke free from Ironclad's arms. During the fight, the Hulk threw Ironclad into X-Ray which caused intense pain from the inside of his body. Suddenly all members of the U-Foes began to lose control of their powers. X-Ray was suffering from severe radiation poisoning and burned himself out when he flew skyward.


    X-Ray was created by Bill Mantlo and Sal Buscema in 1980 and first appeared in The Incredible Hulk # 254.
