Ultrawoman Beth (ウルトラウーマンベス Urutoraūman Besu?) is the female member of the alien trio of Ultras sent by the Space Garrison to fight against the Sorkin monsters. She merged her life-force with Beth O'Brien after accidentally forcing the human to crash land during a jet stunt show. After realizing who they are, the trio agreed to become the Ultra Force of Earth and swore to protect Earth from the arriving Sorkin monsters. She reappeared with the rest of the Ultras from the Ultra Force in Ultra Galaxy Legends to fight against the evil Ultraman Belial.
