>What is Megaman's own Sonic.EXE
In a way, picrel. Or if you want another answer, Nightmare Viruses or High Max technically count and that's not counting Sigma himself, and that's only from the top of my head.
>why is there no such equivalent, even in general creepypasta that reached that sort of popularity
Couple of reasons. By the time creepypastas reached a high point, you know, your Jeff the Killers, your Squidward's Suicides, your Godzilla NES, your MARIOs, etc, the franchise was dormant. Also, it's hard to do a .EXE ripoff when there's literally a series that has a Megaman.EXE, as well as the franchise already having similar characters in ideas. Doesn't help that the playerbase at the time was generally older, so you're much less likely going to get internet slasher horror Mega Man OC number who cares and instead you're going to get a vaguely, poorly written creepypasta over some detective finding out about a cannibal cult because of Mega Man 2.
