His mouth has also become highly deformed with visible veins and melty lips seen in all of his poses. In You Can't Run, his quills are more unruly and have began to develop crystallized tips. In his Encore design, he has a much bigger face and head, with a wider grin, pointed ears, less glowing pupils, and a brighter red microphone. It’s unknown why he has this trait, but it has left rashes under his eyes. His most iconic trait is the blood flowing out of his eyes, a result of a birthmark that constantly pains his eyes.
He has pitch black eyes, usually accompanied by red irises, although this can vary. He has a wide mouth, and his teeth are fanged and yellow, a side effect of when his body was first made. He is sometimes seen to have claws, which are often depicted as either black or purple. His skin is also paler, with a black color fading into his forearms, hands, forelegs, and feet. His fur and quills are a darker blue, less smooth, and more unkempt. Sonic.exe looks similar to Sonic, but with several noticeable differences. Sonic.EXE is the central antagonist of the mod, and the main antagonist of his titular creepypasta.
