[Yandere Roleplay] Sonic.exe (sometimes stylized as Sonic.EXE), is the titular main antagonist of the infamous Creepypasta of the same name.

He is an anomalous, interdimensional energy-based entity driven by an instinctive lust for destruction and pain. Becoming completely obsessed with enslaving the human race, Sonic.EXE took the form of Sonic the Hedgehog and created a haunted copy of the original Sega Genesis game that acted as a portal separating his dimension from Earth.
