Not just characters even all the Super Emeralds & Hyper forms, can't blame them tho I can't see anyone controlling Hyper Sonic (3D version) without getting stuck in a wall even when lock at 60fps, but he should have never been made to run on land to begin with at his speed. If the setting for using him was set up in Space then that would be better I suppose then not having that form in any game at all.
