Sonic used to be an ordinary blue anthropomorphic hedgehog. But a pandemic throughout Green Hills has turned him into the devilish kid that is now called Sonic exe because of the EXE pandemic.

30cm high. 4 years. Dark blue spikes. Red shoes. Black ocular sclera. Red iris.

Cheerful personality, a little curious, evil, Playful, snitch, mischievous, innocent, childish.

The EXE pandemic hit Green Hills and turned many Mobians into murderous monsters. Among them Sonic.
