The Thing That Plagued Sonic(.exe)

That's sonic.exe's black soul trying to escape!

XD

Metallica's title song "The Thing That Should Not Be" would fit it!

Oh yeah! Good thinking!

God that thing is gonna give me nightmares

Metallica's title song "The Thing That Should Not Be" would fit it!

I think you forgot the sonic.exe backstory. he is not a possessed sonic, or the soul of a dead person inside of a game seeking revenge on sonic, he is just a demonic ai inside of a game, who only kills for his own, twisted, diabolical, pleasure's.

That's OG Sonic.exe.

Other variants of him... not so much.

well, let's take a look at Lord x, he is a being from another detention, the world between worlds, or to simply put it, the VOID! he later become Obsessed with with sonic, he isn't posessing sonic, he a very wide spread theory on why he chose this form is because he believes if he takes up the persona of a hero, he can get to them easier, so he might devour them, bodie and soul.
