I stopped playing when Shadow and all these folks were introduced, is he an actual villain or another Knuckles?
Shadows probably the last good character that got introduced, maaaaybe Silver too but honestly I stopped playing by the time Silver came through and I have no clue who the rest of these mfers are
Shadow is hedgehog Vegeta like
@acri1 said, hes not above working with villains but hes more in it for his own reasons than anything and he doesnt fukk with Sonic, tried to kill him a few times but will work with him too if its like... a world ending threat
Metal Sonic or Mecha Sonic is probably gonna be the real big bad of the movie, which would be awesome cause theyre both
