Woo (ウー, Ū Woo?) is a strange supernatural kaiju that terrorized Phantom Mountain, seemingly protecting an orphan girl. After several attempts were made at the girl's life, Woo began to rampage about the mountain and Ultraman intervened. Woo only stopped after the orphan girl succumbed to the cold after being chased by local huntsmen. Woo disappeared, and yet appeared again to fight the choju Iceron several years later.
