The Negatives are the evil twins of the leaders of the witch/wizard world, the DecaWitches. They abhor everything, including the entire witch/wizard world, everything the DW's like, and the fact that they got stuck with goatees. The only one who doesn't hate anything is -10, who, since her "good" twin turned out to be evil, actually loves everything, especially butterflies, ponies, and the Astro Amulet. As a result, she never wants to join in on her sister's plans. -1 has to force her to do evil by attacking her with whatever musical instrument she pulls out of her, er, sleeve. Being evil - well, for the most part - the Negatives are always scheming to take over the universe, only to be foiled by the DW's. Their latest attempt is to steal Alice's Astro Amulet and use it to make Negatives of everybody.
