When Tails stops running and looks at the night sky, it shows a constellation of Sanity's Sonic form. When Knuckles goes to search for Tails, Sanity's Tails form appears and teleports him to a world where physics are broken and he can only talk in Windows pop-ups. He first appears in the form of Sonic when Tails is walking alone after Knuckles gets teleported by Sanity Tails form, in which he proceeds to approach Tails and teleport him to a world reminiscent of the 'Sonic 2.exe' trilogy games.

The Highests and Demons were able to stop the virus from spreading. All living things mutated into terrible monsters. When the energy escaped, it turned into a virus, infecting many worlds.

This virus was made up of corrosive, negative Chaos energy. Nothing is known about Sanity past other than that the X-Dimension that he lives in is corrupted by a Zalgo virus.Ī long time ago, the dying Zalgo released its virus.
