Dark Iguana is one of several prominent villains who appeared in the online parody-comic known as Supermegatopia (SMT for short) as well as related media such as Crushed and Weasel Boy, all of which were created by the Brothers Grin - although the comic has since drifted into limbo the characters have a strong fan-base and several of the Weasel Boy comics have been recovered on wikispace.
Dark Iguana himself is one of the most powerful villains in canon, able to resurrect the dead and countless other deeds - it is little wonder he is a self-proclaimed "God", however he is also an extremely evil individual who continually seeks to destroy the world for his own amusement and is infamous for his open incestous relationship with his daughter, Sunflower.
