The Ultra Beasts (ウルトラビースト Ultra Beast) are identified as extraterrestrial creatures, some of which in the form of Pokémon, that originate from other dimensions or universes. While the ones known in Pokémon Sun and Moon are revealed to be alien species of Pokémon, the ones listed below, in addition to the official ones, are not necessarily considered such. Due to the fact these particular Ultra Beasts have nothing to do with the Aether Foundation, their code names and numbering system is different from the Aether Foundation's naming registry.
