Anti-Rosemary is the only daughter and second child of Anti-Cosmo and Anti-Wanda. Though she takes more after her mother in more than one field, she can have logical thought when she feels like it. Most of the time she doesn't feellike it because she likes messing around with everyone.
She REALLY loves to annoy her older brother, Foop, and is highly overprotective of her younger brother, Anti-William.
