Thankfully, there's plenty of prime numbers to use for the UB's base stats.
The latest trailer for Pokémon Ultra Sun and Moon has shown more of the Ultra Beasts including a brand new Beast.
It appears the trainer will be able to ride the mascots of Sun and Moon in the respective versions in exploring more of the Ultra space, including a new "Ultra Megalopolis" cityspace. The "Ultra Recon Squad", with two members each for Ultra Sun and Ultra Moon, was also revealed.
A new Ultra Beast "UB Adhesive" (pure-Poison type) was shown, and UB Burst and Assembly had their types revealed. Burst is a Fire/Ghost type with the new high-recoil move "Mind Blown", while Assembly is a Rock/Steel type.
