God Complex Sonic is an EXE made by UpTaunt.
God Complex Sonic is a version of Sonic the Hedgehog that formed a god complex because of one of the Chaos Emeralds (it is unknown which one caused this). Now in his paranoia, he kills everything he sees.
God Complex Sonic looks like Sonic, but more manic, with nearly bloodshot eyes and red pupils, scraggly fur and quills, and clawed hands. He also has a lot of blood on his body and has yellowed sharp teeth.
