The boy who would become known as the Kryptonite Kid was traveling through space with his dog, when he passed through a green cloud of gaseous Kryptonite. Exposure to the Kryptonite turned both he and his dog green, bestowing each of them with Kryptonite-based powers.


  • Radiation Production: By way of physical contact, the Kryptonite Kid can transform solid matter into a Kryptonite. Prior to gaining his Kryptonite powers, the Kid was also mildly telepathic.
  • This version of Kryptonite Kid, including all history and corresponding appearances, was erased from existence following the collapse of the original Multiverse in the 1985–86 Crisis on Infinite Earths limited series. Even though versions of the character may have since appeared, this information does not apply to those versions.
