As far as Earth-One and relate alternate realities were concerned, Kryptonite was a transuranium component that decayed to iron and did n’t chemically react with oxygen ( which was used to explain why little rocks of Kryptonite did n’t burn up when entering Earth ‘s atmosphere ). [ 1 ] In the Post-Crisis primary New Earth universe, there is only one natural form of Kryptonite, Green, and it is a compound made up of assorted elements. [ 2 ] All others forms of Kryptonite in the New Earth property are artificially created from Green through certain techniques to produce these other forms, such as radiation sickness bombing to accelerate Green ‘s half-cycle into Red. Luthor has successfully recreated Gold in the New Earth dimension, which strips all power serve of Kryptonians ‘ bodies, though apparently it is only temp in its effect and not permanent, unlike the Pre-Crisis Earth-One Gold Kryptonite. [ 3 ]

Artificial/Synthetic Kryptonite

  • In the continuity of the Superfriends, artificial kryptonite was created by a villain named Doctor Rebos.[5]
  • Ring wielders apart of the Green Lantern Corps can simulate the effect of the jade variant of the isotope at will. Originally only coming up during the Bronze & Silver Ages.[6][7] It has appeared sporadically throughout various instances and it’s lethal potency was just as diverse as it’s scarce appearances, but artificial green K has proven potent enough to critically injure if not outright leave Supermen on the brink of death.[8][9] As certain Kryptonians are immune to different dimension Kryptonite Rays due to the discrepancy of alt. universe Supermen are unaffected by Kryptonite from different worlds. The Lantern in question has to calibrate the energy signature of which to match that of the Kryptonian doppelganger for it to be effective.[10]
  • In a simulation, Grodd used a type of Kryptonite called Artificial Kryptonite. It was a cloud of Kryptonite that masked the Earth, keeping Superman off planet and Grodd as Earth’s ruler.[11]
  • Another version of faux kryptonite was developed by Gus Gorman in the movie Superman III where he substituted the “unknown element” in Green Kryptonite with tar. The result of the exposure to the Synthetic Kryptonite was that it caused Superman’s moral behaviors to change to the point of being evil and destructive, both to himself and to others. It also eventually caused Superman to split into two separate selves, the evil self, and the heroic self, battling for dominance until his heroic self-prevailed, restoring his normal moral behaviors.
  • On Earth-Two, Synthetic Kryptonite was invented by Lex Luthor, using some extremely rare and unobtainable ingredients, including a mammoth pearl, dust from the dark side of the Moon, pollen from the man-eating Asiatic Homocessandi plant, and Binarium.[12] A second formulation of Synthetic Kryptonite was developed by Dr. Vallin, using more readily available ingredients, including gold, silver, lead, and bismuth, fused together with acid and electricity.[13] These forms of synthetic Kryptonite had the same paralyzing effect on Superman as Green Kryptonite,[14] The Luthor synthesis was quite powerful but had a short half-life, such that after a few days of criminal use and some hours spent in a police evidence locker, its charge would fade to a level that was harmless to Superman.[15]
  • Within modern publishing Lex Luthor and a host of other criminal minded individuals got into the business of fabricating K-Rad emission emulations as well as carbon copy green kryptonite to ward off Superman.[16][17] It’s not as effective as genuine Kryptonite but it is potent enough to cause a Kryptonian physical harm.[18][19][20]

When Clark is pricked by this artificial form of Kryptonite, he begins having paranoid delusions and becomes convinced that his friends and family are out to destroy him. Silver Kryptonite causes hallucinations, such as an imagined conversation between Clark and Professor Fine, and delusions that what is actually occurring is, in fact, something much more sinister.
  • In Post-Crisis continuity, Silver Kryptonite demonstrates certain mystical properties that are of great value to the supernatural community. Two known samples of this “magic Kryptonite” have been forged into a pair of twin medallions known as the Ach-om Rashay – the Amulet of Mindfulness. One-half of the amulet was located inside of a volcano on Dinosaur Island while its twin was forged into a stone tablet found at the Oblivion Bar. For Kryptonians, exposure to Silver Kryptonite yields effects similar to that of Cannabis on a human being. Those affected by it experience a loss of inhibition, altered perceptions, extreme hunger cravings, and some psychotropic hallucinations.[21]

This is very different from the second gear Antimatter Ultraman and retentive dead Earth-Three Ultraman who are both powered by the lapp Kryptonite that harms Superman.

Superman tricked Brainiac with his mutation, however, as he waited for his recurrence ( he went into space to monitor the change ) and allowed everyone on Earth to believe the K made him go brainsick, as he would never appear without a hat, and he would act out a hat ‘s properties to solve crimes. He besides used this to cover his eye. Brainiac attacked Superman with a dunce capital, but Superman used the force of heat vision from all three eyes to dissolve Brainiac ‘s pull field. He then took Brainiac into detention. It appears the green K in Red/Green Kryptonite does nothing, although the mutant did last longer than 24 hours, possibly indicating the green K amplified the effects .

Krypton Steel

Appearing alone in the Challenge of the Super Friends episode “ Super Friends, Rest in Peace ”, Krypton Steel was described by Lex Luthor as a “ harmless form of Kryptonite ” that only Superman could break.
