Judeau (Judo) is a member of the Band of the Hawk and is a former circus performer, which is the background for his prowess in knife-throwing. He is one of Griffith's most valued fighters, but his greatest strength comes from his ability to read the emotions of other people, as shown by him being the first to notice the growing bond between Gatsu and Casca, even before the two themselves.

Quiet, calm, and practical, Judeau is often the voice of reason when handling the more volatile Hawks like Corkus. Noble and generous, Judeau usually puts his companions in the band above him, showing himself to be at ease with understanding matters of the heart and inquiring the true intentions of those who surround him. Judeau himself admits that he is pretty good at a lot of things but is not a stand-out in any of them. His honesty and down-to-earth personality make him a kind of "average joe" character that people can easily identify with. Throughout his tenure with the Band of the Hawk, he is secretly in love with Casca, but he never acts on it out of respect for Gatsu's and Casca's feelings for each other.
