Ahh, but unique models can be applied to different color schemes? Theyl just have to fit the same rig as the original model or it wont make sense?
Yes, it's exactly that. Remember that some characters are "ported" or "rel ported", for example Shadow over DK, with this one, you can have any model character of Sonic over DK, working with the Shadow moveset.
OK, so you can have different models for a character (ie Normal Pikachu, Knuckles, Sonic, etc). But its 1 moveset per character. Note that sometimes different models cause problems.
Yes and no, you can have different models only if they are over the original bones of the character's moveset.
