Giygas

Giygas is the true main antagonist of the Earthbound species. Known as both the "Embodiment of Evil" and the "Universal Cosmic Destroyer", Giygas is an evil alien who, upon failing his original mission to reclaim the knowledge of PSI from humans, intends to sentence all of reality to the horror of infinite GoAnimate videos. You can just imagine how much cancer would inflict on people. His influence also causes animals and people to become violent and distressed. He belongs to a race of aliens who originally had the power of PSI and for unknown reasons, abducted humans in the 1900s and 198X.
