Kryptonite

**Kryptonite** is a radioactive mineral from the planet Krypton. Following its destruction, some Kryptonite found its way to the planet Earth.

## Overview

### Green Kryptonite

Kryptonite is normally green and Kryptonians exposed to the element will become weak within close proximity or pierced by weapons laced or made from the substance and prolonged exposure is fatal, Kryptonite's effects are radioactive in nature and therefore cannot penetrate the element lead. The radiation of the mineral can be harnessed and used independent of the mineral itself to harm a Kryptonian, usually appearing in the form of artificial light emitted from certain machinery.

### Silver Kryptonite

A silver colored form of Kryptonite that was found and used by Vril Dox from the vast quantities of Kryptonite that he discovered on his home planet, Colu. This kryptonite will cause a Kryptonian to fall in a deep and frightful hallucination where nothing from the outside world will stir them out of it until it leaves their system. When Superman and Batman confronted Dox, he poisoned Kal and convinced him that Batman was another enemy. While under the affects of Silver Kryptonite, Superman was unable to hear Bruce. Unlike green kryptonite, silver kryptonite will not weaken or dampen a Kryptonian's powers at all. When in vast quantities, it will reveal itself as glowing silver veins on the Kryptonian's skin.

#### Red Kryptonite

Someone created a synthetic red form for an unknown reason. Rather than weaken Kryptonians physically, Red Kryptonite alters their minds by weakening and gradually destroying their inhibitions, as well as bringing out every negative thought to the surface. They can even feel its effects long after they have left its presence. As this happens, red, glowing veins momentarily protrude from the skin when they first come near it and in times when the victim's actions and thoughts are most affected by the Red Kryptonite. Symptoms of Red Kryptonite infection first start as the Kryptonian becoming more abrasive and immature in personality and actions as their mental and emotional restraint is lessened. Eventually, the Kryptonian will be left without morality, patience, rationality or any cares, whatsoever. They can even develop narcissistic tendencies and arrogance that results in an inferiority complex. After having expressed their negative personality traits fully, the Kryptonian will become malevolent and prone to hostility and aggression, leaving them a danger to everyone around them. However, Lex Luthor also developed a cure for it in the form of a red sun casing that would dampen his Kryptonian powers

#### X-Kryptonite

X-kryptonite (sometimes referred to simply as X-K) is a variant of kryptonite. It is yellow in color and can endow humans with some Kryptonian-like powers.

#### Blue Kryptonite

The blue, molecular opposite of green kryptonite was created by Ray Palmer by reversing the ionic charge of green kryptonite. While blue kryptonite has no effect on Kryptonians, it severely weakened Bizarro and sedated him, allowing him to be apprehended. It also seemed to have a calming effect on Bizarro, removing his rage toward Superman and allowing him to think rationally.

## Behind the scenes

Comics

In the DC comics, there are several different types of Kryptonite;

* **Green Kryptonite:** Green Kryptonite can weaken a Kryptonian's physical attributes, however, the radiation effects of green kryptonite are harmful to humans given sufficient long-term exposure, resulting in cancer.

* **Red Kryptonite:** Like Green Kryptonite, Red Kryptonite can weaken a Kryptonian's physical attributes; but to a greater degree.
* **Anti-Kryptonite:** Anti-Kryptonite is harmless to Kryptonians; but has the same effect as the green variety on normal humans.
* **X-Kryptonite:** X-Kryptonite is harmless to Kryptonians; but it gives normal life-forms superhuman powers.
* **Blue Kryptonite:** Blue Kryptonite can affect Bizarro in the same way the green variety of kryptonite affects Kryptonians; blue kryptonite is the antidote to the random and bizarre effects of red kryptonite. Generally it is harmless to real Kryptonians. In some fiction, however, it can strengthen the normal physiology of Kryptonians or even heal their wounds.
* **White Kryptonite:** White Kryptonite can kill all plant life, from any world.
* **Red-Green Kryptonite:** Red-Green Kryptonite caused Superman to mutate, temporarily growing a third eye in the back of his head.
* **Gold Kryptonite:** Gold Kryptonite can remove Kryptonians' powers to process yellow sunlight; this kryptonite only removes a kryptonian's powers temporarily, but enough exposure can render them powerless forever.
* **Red-Green-Blue-Gold Kryptonite:** Red-Green-Blue-Gold Kryptonite can enhance the intelligence of a Kryptonian.
* **Silver Kryptonite:** Silver Kryptonite can causes Kryptonians to suffer from altered perceptions, loss of inhibition and extreme hunger cravings.
* **Jewel Kryptonite:** Jewel Kryptonite allows the individual(s) to project illusions or perform mind control.
* **Bizarro-Red Kryptonite:** Bizarro-Red Kryptonite affects normal humans the same manner that red kryptonite affects Kryptonians.
* **Red-Green Kryptonite:** Red-Green Kryptonite caused Superboy to permanently lose his powers.
* **Red-Gold Kryptonite:** Red-Gold Kryptonite temporarily deprives Kryptonians of their memories.
* **Magno-Kryptonite:** Magno-Kryptonite is magnetically attracted to all substances originally from Krypton.
* **Red-Green-Gold Kryptonite:** Red-Green-Gold Kryptonite can permanently remove the individual's powers and memories of ever having been Superman.
* **Slow Kryptonite:** Slow Kryptonite affects normal humans in a manner similar to green kryptonite.
* **Kryptonite-X:** Kryptonite-X can supercharge a Kryptonian and restore his/her ability to process solar radiation.
* **Pink Kryptonite:** Pink Kryptonite turns Kryptonians lesbian, gay, bisexual or transgender.
* **Black Kryptonite:** Black Kryptonite can split a Kryptonian into two separate entities; one good and the other evil.
