Ushio is a security staff who observes residents around the Satellite area. He has a violent character but holds high esteem as a duelist on his muscles. If you remember, Ushio appears once in the first episode of Yu Gi Oh series 0. He is a bad character who acts as a student guard and tries to get money from the students for his protection service. Yugi used to be one of his victims. He has starred in all Yu-Gi-Oh series so far expect for Capsule Monsters. In the first series, he bullied Yugi in one episode, and the same event was featured as a flashback in Yu-Gi-Oh Duel Monsters. In Yu-Gi-Oh Duel Monsters GX he was mentioned as being one of Trueman's victims and in Yu-Gi-Oh 5D's he plays a big supporting role.
