Xium was an element isolated by Lex Luthor between incarcerations in Metropolis Prison. It contained an astonishing amount of power for its size.
History
Earth-One
The element was small enough and radioactively stable enough that Luthor hid it in a hollow tooth; using it to power an Atomic Transmitter, and generating a Super-Ray that would give a human being powers to rival Superman. Through trickery, Clark Kent -- Luthor's unfortunate choice for test subject -- made Luthor think that Xium withdrawal caused the user to give away all their wealth. And thus Luthor destroyed the Xium.
Earth-Two
Xium is a mineral whose properties can be used to fuel and power black magic. Chameleon and Strogo once teamed up to steal some, but Wonder Woman ground the deposit they were after into dust.
Notes
- Because Luthor tested the Xium-powered Super-Ray on Clark Kent and his powers as Superman were unchanged, there was no way of knowing if the Super Ray actually worked.
