So Sonic.exe is a creepypasta character that likes to kill and Sonic.exe is a god. he killed Tails, Knuckles and EggMan. and Sonic.exe is Horror. and then we got Mario.exe. Mario.exe is also a creepypasta character that likes to kill, but no one's really sure if Mario.exe is a god. and Mario.exe he has killed Luigi, Toad, princess peach and many more. and the difrences between them is that one is a plumber thats an exe and one is a blue hedgehog that is an exe.
