MX is the main antagonist of the Creepypasta based game Mario 85, which takes place on an original 1985 Super Mario Bros. game software ─ with a dark twist.

|| "ARE YOU READY? マジで DREADING? それは無駄だ" - Rewrite || This entity appears to be a demonic entity that somehow became part of an AI program that was made by an exploitative priest that wanted to create something to deceive people of the time, and get easy money on top of it. This, of course, backfired greatly and might have created a looming evil in the world. This character, created by SpringlessEcho, is an egocentric demonic entity that was somehow given the purpose of being a digital version of God himself. He went rogue, killed his creator and has gotten loose all because a bunch of his copies remained loose and, worse, the internet that loomed it's head in the 90's (with the lack of security that exists nowadays).

A japanese spirit that feeds on childhood innocence, mainly preying on young fans from the Sonic Franchise. But he's been recorded mentally harassing adults too. He's managed to spread to America through Sonic 2 Bootleg cartridges. These anomalous objects are dangerously addictive on the victims. Implied demonic influence.

Somehow after being spared by The Slenderman, things started to become weird. At least, most specifically, the week after. He was still following you, of course. Maybe even protecting you, in his own way. You didn't know why, but you didn't mind...
