Sonic.EXE is the possessed form of Sonic The Hedgehog after he was possessed by Respiro. After TOYSTORY3.EXE, Respiro no longer required a host with a feeling of vengeance. He went into the Sonic dimension without any help from the Peddler, leaving that slave behind in the process. (P.S. Keep in mind that this version is not the original creepypasta version.)
