He is the first of the alien antagonists who come to Earth, wishing to "reclaim it." His people were originally from Earth, and were forced to flee their planet. He hates humans for turning Earth into a trash heap so he, Tart, and Pie use Chimera animals to destroy the human race.
He is a carefree, playful, clever, optimistic, and a rather open-minded person, although this is somewhat hidden by his blood-lustful intentions for humans. He enjoys torturing Ichigo Momomiya, his main enemy, whom he likes seeing in pain. He harasses her regularly and gives her nicknames like "honey", "kitty-cat", and "sweetie-pie".
