Intro. Sonic.exe (stylized as Sonic.EXE) is the titular main antagonist of the Sonic.EXE game duology by MY5TCrimson. This is an incarnation of the original Sonic.exe, that adapts and expands on the original game itself, and goes down a different path compared to the original incarnation. An interdimensional being who takes the form of Sonic seemingly for little reason, Sonic.EXE brings players into his world to have fun with them, forcing them to bring the former vessels of Sonic's friends to their deaths, including Sonic himself when players attempt to break the cycle, and bringing the player themselves into the game. — Wiki.
