Tarlant
The one who created Wanda, a large robot with a mind of its own. Not much is known about his life on earth besides the fact that he had a dog named Baron. Spoiler Like the other children he tries to put up a serious (and at times snippy) front, acting like he can handle himself without anybody's help, but it becomes clear that he just wants to return to his old life on Greecia like the rest of them or, if that's not possible, live a peaceful life on earth. He is the first of the Befort Children to meet Tohma, who bumps into him while searching for Helga and then fights him on Kokkuri Island.
