All over Alola, rumors speak of creatures that possess mighty powers and pose a threat to humans and Pokemon. They’re called Ultra Beasts, and there are said to be multiple Ultra Beasts in existence. It seems that the Aether Foundation is conducting research on these Ultra Beasts, referring to each of them by a code name. UB-01 is an Ultra Beast that has a body composed of a glass-like substance. It constantly changes shape, and its movements resemble that of a young girl. Whilst evidence of something like a survival instinct can be observed in UB-01, no one knows whether it has a will of its own or any emotions at all.
