Sonic movie

In my AU Shadow and Sonic both lived on the planet where Sonic lived in the movie, they both grew up and were best friends until the accident with Long-Claw happened and Sonic had to leave his home and also Shadow. Years later, Eggman took Shadow to protect Maria and yeah well basically he made Shadow work for him(So basically Eggman took Shadow for him and Shadow lived there since he was a kid) . Then, when Shadow was grown up the other accident happened when Maria got shot and died and sent Shadow to Earth. So basically Sonic and Shadow were living apart from each other for a long time. REMEMBER THIS IS MY AU SO THE THINGS HAPPENED DIFFERENTLY!!!!!!
