Exe greatly idolizes Sonic the Hedgehog to the point of unstable fanaticism, willing to do whatever it takes to have him all to himself when he rules. Whenever Sonic acts the opposite of the hedgehog Exe loves, Exe expresses great disappointment.

Sonic. EXE is an eldritch entity taking on the form of Sonic the Hedgehog that sends out a haunted game disc featuring the creature killing the main Sonic characters, eventually leading him to rip out the soul of his victim and making them his slave.
