This is what I believe Sonic would look like if he were in Kingdom Hearts. I used references of Mickey, Donald and Goofy's looks from the games and tried to give Sonic's gloves and sneakers some of that Kingdom Hearts flare. I also wanted to show him with the keyblade I designed for him (I had a little trouble drawing it at that angle so it may not be completely accurate ). I might make keyblades for some of the other Sonic characters, but I don't plan making one for everyone (there are only a few that I would find have a strong enough heart to have a keyblade).
a sort of, realisation of Shadow in real life, as a human, i got kinda bored. its meant to be that dark before anyone says otherwise heh.
anyways yeah, i did the inital sketch of shadow, then i got into it and thoguht i could carry it on. originally it was jsut a human, but then i gave him the shadowy hair and gave him hedgey-hog ears heheh.
