“I use a shotgun!”
—Goanna67, Destroy the Godmodder 2
Goanna67 was a troll player of the Destroy the Godmodder series. His true faction was indeterminate, as were his true motives. He was infamous for occasionally popping up and making troll attacks that didn't contribute to the actual game in meaningful ways, such as posting pictures of guns and attacking nonspecific targets. Goanna's actions made him a meme in the eyes of the players.
During the end of Destroy the Godmodder 2, TwinBuilder placed Goanna within a Lotus Eater Machine which trapped him in an imaginary dream world. Stuck in this world, Goanna believed that he was the current and forever President of the United States of America. He seems to have become inactive following the release of Destroy the Godmodder 0rigins, though only time will tell if he returns.
TT2000, the Pinary ARG, and DTG2's post-canon content revealed that Goanna is actually one of the most intelligent players, and is far too powerful to be portrayed normally in the DTG series. TT2000 introduced the concept of an invincible automaton known as Goannabot that helped to destroy the Incarnate. The Pinary ARG showed that Goanna is aware that he is trapped in an imaginary world, and is trying to escape. The end of Infamy revealed that Goanna successfully escaped. He promptly captured Build with the intent of locking him inside his own mindscape for eternity as revenge.
