Lex Luthor was a powerful businessman and criminal mastermind. He was widely considered to be one of Earth's most brilliant minds and one of Superman's greatest enemies.
Luthor's lust for power eventually made him the sworn enemy to Superman. From the start, the very idea of an alien who appeared to be human possessing incredible power disturbed Lex. The fact that Luthor could not bribe or hire the newcomer, or alter the public's perception of Superman's actions, angered Lex all the more.
Luthor took to carrying a small piece of Kryptonite on his person at all times, as a precaution against any potential encounters with Superman. However, not even Luthor realized how damaging the radiation could be to humans and after a few years, he developed Kryptonite poisoning.
The Battle Attack armor came in 4 pieces which you snapped onto his chest and legs, arms and neck. With the armor, only the arms are movable. However, his real hands are visible from under the arm pieces.
