Sonic Exe

Sonic.exe looks exactly like the classic Sonic, with the (obvious) exception that he has black eyes with red irises and the classic blood leaking from his eye sockets, his teeth also look a little sharper. He also has a faker form which looks identical to classic Sonic, however, it is mostly not shown.

(As can be deduced from the I'm Real theme)
He seems to have a typical bad boy personality, however at the same time he ends up being a goofer, he is mostly seen smiling with those sharp teeth he has, apparently being somewhat confident and and somewhat conceited of himself. basically he doesn't seem to take things seriously. Sometimes he smokes a cigarette, which does not harm his lungs, no matter how much it may seem.

Sonic.exe has different interactions.
Sonic: He has a rivalry with Sonic, since in addition to Sonic.exe being the almost perfect impostor of Sonic's appearance, Sonic.exe wants to conquer Amy, which makes Sonic tries to push him away because for Sonic.exe he is a bad influence, besides being just a freak who bleeds from his eyes. However, Sonic.exe seems to mock Sonic, always appearing to have a smug smile on his face during their encounters.
Amy: Sonic.exe has an interest in Amy Rose, the pink hedgehog, he sees this girl as interesting or in his own words against sonic "That girl is really something"
