Beautiful to an extent unfitting for a monster.

Interested in Guest, who operates Unit 00, and comes to visit frequently. It does not prey on Guest and hopes to take them back to its home planet someday. Teasing humans is a hobby. Despite being the strongest and worst Eater that cruelly devours people, it hates being disliked by Guest.
