10 Things You Didn't Know About The Green Lantern Corps

7. There's An Evil Version

There are a number of villainous characters in DC Comics who have gone by the name "Power Ring". They are evil alternate reality counterparts of Green Lanterns Hal Jordan, Kyle Rayner and John Stewart, respectively. Having originated from Earth-Three initially - Earth-Three having since been destroyed during the twelve-issue Crisis on Infinite Earths arc - Power Ring, along with the other Syndicate members, ended up being re-created in the Anti-Matter Universe and have appeared in the current New 52 continuity. Instead of wielding a ring created from advanced technology like the standard Green Lanterns, the evil versions wear a magical ring powered by a cosmic entity known as Volthoom. They have crossed over into the mainstream DC universe and have fought against the heroic Green Lanterns and the Justice League - usually as part of the evil group known as the Crime Syndicate of America.
