Sonic.OMT (or "Outbreak Malware Threat") is a sadistic entity that has played through the original Sonic.exe story countless times and has grown bored, deciding to "change things up" for a final, more brutal round Evolution of Gameplay:
You will eventually face Sonic.OMT in a scripted boss encounter. Knuckles will attempt to punch OMT, but the monster teleports away just before impact, slowly draining Knuckles' stamina.
