Forms of Kryptonite

Kryptonite is a crystalline compound formed from the radioactive elements which constituted the core of Kal-El's native planet, Krypton. Existing in many forms with many colours, kryptonite has varied effects on Kryptonian and Terran lifeforms alike.

GREEN KRYPTONITE

EFFECTS ON KRYPTONIANS

Causes debilitating pain, weakness, reduction of powers, and eventually death.

EFFECTS ON HUMANS

Prolonged exposure causes cellular damage.

EFFECTS ON BIZARRO-KRYPTONIANS

Permanently amplifies/augments powers and temporarily immunizes them to most other forms of kryptonite.

ABUNDANCE

The only known form of naturally occurring kryptonite, the molten remains of Krypton and the debris field surrounding it are believed to be wholly composed of green K. Only one (formerly three) fragments of appreciable size are present on Earth — formerly in the possession of Luthor Incorporated, now in the hands of parties unknown.

RED KRYPTONITE

EFFECTS ON KRYPTONIANS

Suppresses powers for 48-72 hours.

EFFECTS ON HUMANS

Prolonged/intense exposure in combination with various external catalysts causes mutations resulting in superhuman abilities.

EFFECTS ON BIZARRO-KRYPTONIANS

Fatally overloads them with power.

ABUNDANCE

The end product of Lex Luthor's failed attempt at synthesizing green K, almost a hundred bricks of red K were produced during the 1930s & '40s, making it the most common form of the compound on Earth.

BLUE KRYPTONITE

EFFECTS ON BIZARRO-KRYPTONIANS

Causes debilitating pain, weakness, reduction of powers, and eventually death.

EFFECTS ON KRYPTONIANS

Permanently amplifies/augments powers and temporarily immunizes them to most other forms of kryptonite.

EFFECTS ON HUMANS

Prolonged exposure heals cellular damage.

ABUNDANCE

Naturally occurring in Universe 29, the only example of blue K found in Universe 1 was a large synthetic crystal Superman had kept in his Fortress of Solitude before having it destroyed.

BLACK KRYPTONITE

EFFECTS ON KRYPTONIANS

Splits them into two separate beings, one "good" and one "evil".

EFFECTS ON HUMANS

None known.

EFFECTS ON BIZARRO-KRYPTONIANS

None known.

ABUNDANCE

The only fragment of black K was created by Lex Luthor and used to fuel the Lexdroid, an android simulacrum Luthor built to physically combat Superman. The chunk was destroyed after Luthor remotely triggered the Lexdroid's self-destruct, bathing the Man of Tomorrow in concentrated black K radiation.
