Powers: Cosmic rays transmogrified Darnell into an anthropomorphic wisp of concentrated radiation. He can fly, he can turn himself invisible, and he’s almost entirely invulnerable to physical attacks; the only things that seem to affect him are items built from substances naturally resistant to radiation. He can fire concentrated bursts of radioactive force that can destroy physical objects and stagger enemies. Even when he doesn’t destroy anything, S.H.I.E.L.D. now knows enough about the long-term effects of radiation exposure to understand it’s never a good idea to have X-Ray around for long.
Known History: Darnell was an engineer and rocket fuel scientist who was part of Simon Utrecht’s fateful space voyage through a volley of cosmic rays. Utrecht told his passengers they’d all have superpowers like Reed Richards and the rest of the Fantastic Four acquired in similar circumstances. Bruce Banner (in his non-Hulk form at the time) brought their ship back to Earth before they’d all gotten their fill of radiation. They never forgave him for it, and the U-Foes (as they call themselves) have been a thorn in the Hulk’s side ever since.
Observations: “Fun fact: Darnell’s sister Ann turned into Vapor. Quite literally. That’s what she goes by these days.” — Jasper Sitwell
