Kryptonite

Kryptonite is a radioactive chunk of the destroyed planet Krypton. Its unique brand of mutant radiation causes it to have varying effects on the people exposed to it.

Variants

 * Green Kryptonite: The most common form of Kryptonite. Green K, as it's sometimes called, glows with radioactive energy that has different effects depending on the person.
 * Effects on Kryptonians: Weakens Kryptonians by slowly draining the solar energy in them. Initial exposure causes symptoms similar to the flu but the symptoms increasingly get worse and eventually result in death. Depending on how long the exposure to the substance is, its effects can linger for some time.
 * Effects on Humans: No effect on most humans but humans with a sleeping Meta Gene have it awoken by exposure to the Kryptonite. Long-term exposure results in a unique poisoning called Kryptonite Cancer.
 * Effects on Bizarros: No effect.
 * Note: The supervillain Ultraman gets his powers from Green K.
 * Red Kryptonite: The second most common form of Kryptonite. Red K emits a different radiation from Green K for unknown reasons.
 * Effects on Kryptonians: Completely destroys the Kryptonian's ability to hold back, causing them to become more violent, anger-prone, and sadistic than normal. Constant exposure creates some kind of mutation, the most common of which being the Kryptonian splitting into two people.
 * Effects on Humans: Unknown. Seemingly none.
 * Effects on Bizarros: Stimulates the Bizarro's mind, causing them to become hyper-intelligent.
 * Pink Kryptonite: A slightly more uncommon form of Kryptonite that emits an even more unique form of radiation than Green or Red K.
 * Effects on Kryptonians: Seems to act as an aphrodisiac and makes them more willing to mate. It also appears to make their sexuality a bit more fluid, as Superman began flirting with men when under the influence of it.
 * Effects on Humans: No effect normally. If ground into dust and sorted or huffed in any way it will create a false Meta Gene and grant the human a random power. People who already have a Meta Gene have their powers amplified. Repeated taking of Pink K causes addiction and madness.
 * Note: Theorized to be the primary ingredient in Velocity 9.
 * Effects on Bizarros: Unknown. May act as nourishment, as Bizarro ate it when first exposed.
 * Blue Kryptonite: An uncommon form of Kryptonite. Emits radiation that is similar to Green K but to a lesser extent.
 * Effects on Kryptonians: No effect.
 * Effects on Humans: Temporarily heightens intelligence when ground into dust and sorted. Overdosing causes the brain to no longer be able to keep up with the body and can cause a seizure, stroke, or death.
 * Effects on Bizarros: The same effects as Green K has on a Kryptonian.
 * Note: The supervillain Ultraman was weakened when exposed to Blue K. Seemingly has the same effects on him as Green K does to a Kryptonian.
 * Black Kryptonite: A rare form of Kryptonite that emits an even stranger form of radiation.
 * Effects on Kryptonians: Works similarly to the final effect of Red K as it can completely split a Kryptonian into two.
 * Effects on Humans: Exposure to Black K mutates the genetics of humans and makes them similar to a Kryptonian, granting them Kryptonian abilities. Will ware off after an hour but if somehow turned to liquid and injected the effects will become permanent. Also gives the person all of the usual Kryptonian weaknesses.
 * Effects on Bizarros: The first Bizarro was killed by Black K, causing his body to spontaneously combust and then explode. Possibly caused by Bizarro's mutant DNA being unable to properly handle the Black K's radiation.
 * Gold Kryptonite: The rarest form of Kryptonite which emits radiation similar to Green K but to a far greater extent.
 * Effects on Kryptonians: Is able to be used as a weapon, able to cut through a Kryptonian's normally indestructible skin. Constant exposure will completely drain the Kryptonian's powers, requiring repeated bathing in the sun to fix. If exposed to Gold K for too long, the Kryptonian will no longer be able to absorb sun rays and be rendered effectively human.
 * Effects on Humans: Currently unknown.
 * Effects on Bizarros: Seemingly increases the amount of solar energy in Bizarros, granting them increased strength, reflexes, speed, and durability. Comes at the cost of the Bizarro's mind, causing them to begin acting on base instincts.
