Which would also see Purple Kryptonite turn him into a raging sex maniac (yes I remember the bizarro purple K but this would be more fun). Black kryptonite would…? ---

Black Kryptonite would make Superman evil. How about Grey Kryptonite? Chocolate Chip Kryptonite? Kryptonite Lite? ---

**Twin** : > [@](#): > > X-Kryptonite: Only one chunk, it was created by Supergirl trying to find a cure for Green K. It gives Terrans, or at least Terran cats, Kryptonian style powers for a limited time. Terran people as well as cats. I read a Supergirl story once where a criminal got hold of a tiny grain of X-Kryptonite, and he used the powers it gave him to cause mischief. And he swallowed the grain so Supergirl couldn’t take it away from him. But here’s the thing: unlike everything else from pre-Crisis Krypton, kryptonite (in any form) doesn’t become indestructible under a yellow sun (although it does become friction-proof, which is why so much of it keeps turning up on Earth). So the criminal’s stomach acid dissolved the grain of X-Kryptonite, his powers vanished, and Supergirl made the collar. ---

Do pieces of kryptonite just glow, or are they actually surrounded by a nimbus, or halo, of visible light? ---

It glows, just like all radioactive elements. Knowing this, of course, we now can explain why the radioactive rod that Homer Simpson takes home with him each week does not affect him or anyone in Springfield. Since it glows green, it’s not plutonium, but rather kryptonite. Mr. Burns has found out the way to harness green K’s energy (another reason he can run the power plant with all those safety violations). Further, the green-K power keeps Superman from snooping around looking to enforce those pesky OSHA regulations.
