Red kryptonite was the result of a shower of regular green kryptonite from the destruction of Krypton
passing through a strange, red-hued cosmic cloud. The debris that made it to Earth provoked effects on Superman
that were never replicated, as he gained an "immunity" from that effect.
Some of the documented effects from this era include:
- Mental telepathy,
- Uncontrollable hair and nail growth
- Transformation into a Kryptonian monster known as Drang
- Temporary insanity
Post-Crisis Mister Mxyzptlk
creates what he calls red kryptonite in the "Krisis of the Krimson Kryptonite" story arc but it has no radioactive properties at all; Superman's depowering is all the result of Mxyzptlk's magic until Luthor
unknowingly breaks the rules of his agreement with Mxyzptlk. The first appearance of actual red kryptonite is as a synthetic variant created by Ra's al Ghul
, using notes stolen from Batman
. This version of the Red Kryptonite causes Superman intense pain (but not to the lethal levels of Green Kryptonite) as well as his powers to behave oddly and his skin to become transparent. Later, a piece of Red Kryptonite found by Ambush Bug
and brought to the Fortress of Solitude
caused him and Superman to switch their bodies for 48 hours. In The Brave and the Bold
series, the cloud was drawn to Earth by the deranged alchemist Megistus to shield humanity against the effects of the Final Crisis
by warping it into something totally different; the villain Doctor Alchemy
also proved capable of transmuting the Fortress of Solitude
in its entirety into red kryptonite using his philosopher's stone

Lois & Clark: The New Adventures of Superman
ed kryptonite initially caused Superman to become apathetic. It was hypothesized that, given enough exposure to red kryptonite, Clark's condition would become permanent. However, after talking to a psychiatrist, Clark was able to resist the effects of the red kryptonite, and he picked up the rock and threw it out of a window. Its later appearances included a red kryptonite laser which caused Superman's powers to transfer to Lois, and exposure causing Superman's powers to be increased beyond his ability to control them.
Red kryptonite has a drug-like effect, causing severe changes in Clark Kent's personality. Under this influence, Clark loses his inhibitions, becoming unpredictable and acting purely on erotic and selfish emotions. Once he ran away to Metropolis and became a criminal who broke into automated-teller machines to impress girls with expensive toys such as sports cars. He also stole his father's credit card to buy large screen TVs and high end audio equipment. Smallville
red kryptonite requires close contact with skin to be effective, such as being worn in a ring or necklace.
