Super Spaceman

The Super Spaceman was an alien who stole Superboy's super powers with the aid of an Energy Transference Device. He is eventually defeated by Superboy and his superdog Krypto.

Super Powers

 * Energy Enhancement: Thanks to absorbing all of Superboy's energy, his physiology was altered, giving him Kryptonian super powers, although they were removed from him after his defeat.
 * Solar Radiation Absorption: Due to the Kryptonian energy he absorbed, he had all of the Boy of Steel's powers, as long as he was absorbing the sunlight of a yellow sun.
 * Super Strength
 * Invulnerability
 * Flight
 * Super Speed
 * Heightened senses
 * Various vision based powers
 * X-ray vision
 * Heat-vision
 * Telescopic vision
 * Microscopic vision
 * Superbreath

Abilities

 * Advanced hand-to-hand combat: As a soldier, presumably he would be efficient in combat. He did hold his own against Krypto, who himself is a well trained dog. He did eventually lose however.

Weaknesses

 * Kryptonite: Presumably Kryptonite of various types can affect Super Spacemen, as long as he has Superboy's powers.
 * Magic: Magic is essentially the manipulation of primordial energies, as such, much of it is more powerful even than the Boy of Steel, and the same would likely be the case with Super Spaceman.
 * Red Solar Energy: Any solar system that the Super Spaceman might enter that has a red sun, would drain his powers.
