Across the Alola region, rumours swirl around creatures that possess mighty powers and pose a threat to humans and Pokémon. These are called Ultra Beasts, and it is believed that there are multiple Ultra Beasts in existence.
In Pokémon Sun and Pokémon Moon, the Aether Foundation is conducting research on these creatures and referring to each of those that they have discovered with a code name.
UB-01 is the first that The Pokémon Company has revealed, which 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. Evidence has shown something similar to a survival instinct stirring in UB-01, but is undetermined whether it has a will of its own or any emotions at all.
Pokémon Sun and Pokémon Moon will release exclusively for Nintendo 3DS in North America, Australia and New Zealand on November 18th, and in Europe on November 23rd.
