Power Ring was the third holder of the cursed ring after Joseph Harrolds and an unnamed man who may possibly have been called Kyle Rayner. He was previously a slave marine.
He was a member of the Crime Syndicate of Amerika of the Antimatter Universe and was his world's evil counterpart to the John Stewart Green Lantern.
Note:The 'Earth 2' in the origin story [JLA: Earth-2 vol 1 (Jan 2000)] is actually the name the Antimatter Lex Luthor gave to the DC Primary Earth. Nonetheless, some references treat the Antimatter Earth as the titular Earth 2. In reality it is not related to Earth-Two, Earth-2 or Earth 2.
