Anti Cosmo is super polite, smart, devious, and nice. He is an "evil" genius. He speaks in a very posh British accent, and is very well-rounded. He hates any idiot in the world, and loves it when they get hurt, both on their free-will, and what Anti Cosmo himself, can inflict on them. He loves Friday the 13th, as does every single anti fairy. He is very devious and will manipulate himself out of any situation. He is super clever and witty.
