Klorgbane the Destroyer

Description
Clorgvain was seen in Fists of Justice. He was the main antagonist, and he was related to The Guardians of Eternal Youth, as their "evil brother." He was not seen in any other episode. He has to fight Skips every 157 years. His main goal is to defeat Skips, and reign over the Realm. He fought Skips for a while, and was beating him, until he lost to Mordecai and Rigby.

He wears a black helmet or hat, a black cape, a black diaper or pair of underwear, black socks, and two sliver/black bracelets. He also has a red glow around him (as opposed to The Guardians white one).
