Over the years, Luthor has created (either on his own, using alien technology he acquires, or with the resources of LexCorp and the military) many highly advanced weapons, machines, and robots to carry out his plans or destroy his enemies. He has made liberal use of kryptonite weapons capable of injuring Superman and other Kryptonians, and he has often created synthetic kryptonite (not as lethal as real green kryptonite but still capable of weakening a Kryptonian). Since the Bronze Age, he has also utilized various high-tech "war-suits" in many stories. The first warsuit, introduced in 1983, was a product of lost science from an earlier age in the planet Lexor's history when technology was highly advanced. Its Lexorian materials can withstand several attacks by Superman before sustaining damage and its force field offers further protection still. Wearing it grants Lex great superhuman strength, not equal to Superman but still enough to overpower many of Earth's heroes. The suit can deliver powerful energy blasts and a molecular sheath capable of blocking Superman's body from absorbing energy from solar radiation, meaning his powers will weaken over time. Powered by red solar radiation, the suit can also deliver red solar beams to directly weaken Superman. The suit has other features including advanced sensor systems, a hypnotism weapon, and illusion casting technology.
