Other Forms Of Kryptonite
Gold Kryptonite: Removes superpowers from Kryptonians permanently
White Kryptonite: Kills all plant life, whether Kryptonian or not. Induces decay immediately upon exposure, with a range of about 25 yards.
Blue Kryptonite: The result of using Professor Potter's "duplicator ray" on some Green Kryptonite. Blue Kryptonite makes Bizarros become coherent, polite and goodhearted; it also alters Bizarros' distinctive grammar, so that a Bizarro would say "I am Bizarro" instead of "Me am Bizarro".
Anti-Kryptonite: Has no effect on superpowered Kryptonians, but has the same effects as Green Kryptonite on non-superpowered Kryptonians.
X-Kryptonite: Created by Supergirl while experimenting with Green Kryptonite in hopes of finding an antidote. It has no effect on Kryptonians, but bestows temporary superpowers on Earth lifeforms.
Jewel Kryptonite: Jewel Kryptonite amplifies the psychic powers of Phantom Zone residents, allowing them to project illusions into the "real world" or perform mind control. It was made from what was left of a mountain range on Krypton called the Jewel Mountains.
Slow Kryptonite: A modified variety of Green Kryptonite produced by a human scientist that affects humans in a manner similar to Green Kryptonite on Kryptonians.
Magno-Kryptonite: Artificially created by the villain Nero, "Magno-Kryptonite" is magnetically attracted to all substances originally from Krypton, with such incredible force that not even the strength of Superman or Bizarro can escape it.
Bizarro Red Kryptonite: Affects humans the same way Red Kryptonite affects Kryptonians.
Kryptonite-X or Kryptisium: A form of filtered/purified kryptonite. Professor Emil Hamilton used the term "Kryptonite-X" to describe the substance that restored Superman's powers after a confrontation with the villain known as the Cyborg Superman in Engine City. This substance eventually led to Superman becoming an over-muscled giant, due to his accelerated sunlight absorption and overstorage of energy. This kryptonite is not to be confused with X-Kryptonite.
