Wikipedia
An owlbear (also owl bear) is a fictional creature originally created for the Dungeons & Dragons fantasy role-playing game. An owlbear is depicted as a cross between a bear and an owl, which "hugs" like a bear and attacks with its beak. Inspired by a plastic toy made in Hong Kong, Gary Gygax created the owlbear and introduced the creature to the game in the 1975 Greyhawk supplement; the creature has since appeared in every subsequent edition of the game. Owlbears, or similar beasts, also appear in several other fantasy role-playing games, video games and other media.
