[UPDATE: ADDED GLOWY EYES FOR INCREASED SPOOK]
it IS Sonic.exe, Except I just don't get how that's so popular. I mean, It's a cheesy Creepypasta, and I'm preeetty sure that that sprite where he's floating/flying after you, is simply the same as one of Metal Sonics attacks, Either V. Max Overdrive or simply His Flying sprite, it also depends on which "Version" of Sonic.Exe That it is.
It looks like Sonic.Exe. that explains why it is so popular.
how the heck did this get FP.... I mean, this was literally meant to be just another one of my joke saves. All I did was take Sonic, make him dark Blue, and give him Eyes that would make him Easily confused for Metal Sonic.
i gotta say these spook saves are getting old pretty quick
