Well, I don't think Antithesis should take their actual shapes. If we're gonna go with the four main character forms, there should be some weird/grotesque differences in each form that are specific to Antithesis itself. It could be, for example, tentacles, etc.

It doesn't even have to be a 'shadow' form. Antithesis' forms could look almost exactly like the party characters, but with these disgusting/evil-looking differences.

Antithesis may be able, in these forms, to take on the abilities of the party character in question. So, Antithesis' Charlie form would be able to take control of any party character. This will make Antithesis much more challenging to defeat.
