Klorgbane the Destroyer was first seen in "Fists of Justice" as the main antagonist. He is related to the Guardians of Eternal Youth as their "evil brother". He has to fight Skips every 157 years. His main goal is to defeat Skips and reign over The Guardians of Eternal Youth's Realm as part of the council. He fought Skips for a while, and was ultimately beating him, until he lost to Mordecai and Rigby shortly afterwards.
