All vanilla characters need their super form.

This issue me and many others have in srb2 hasn't been touched at all.
The fact that you have to collect all emeralds, and find ALL 200 emblems JUST for the rest of the cast to go super. It makes the game less rewarding. Rendering emeralds useless if you're not using sonic or metal.
PLEASE, I beg of you, give them their super forms.

And we're not going to go over all of that again.
