Sugar Belle stood out as the one with the most character, although I actually preferred her while she was equalised. She had memorable lines like "we have: muffins" and the confused speech about how the mane 6 had differing opinions but were still friends. Also Party Favour gets a mention for the whole sacrificing himself for the sake of his friends routine.

It is not that surprising that Double Diamond seemed the less interesting, he was the one who accepted the equalist ideals the most, and he was essentially Starlight's number one henchman.
