There's a new trailer out for the Pokemon Sun and Moon games that showcases two more of the mysterious Ultra Beasts. Each of these two new Ultra Beasts seems to be a version exclusive. Take a look.
Also, here's what little info that serebii.net has on these new Ultra Beasts.
UB-02 Absorption: The extent of its strength is unknown. Its entire body is covered with bulging, powerful muscles. The full force of a punch powered by these muscles would be off the charts! Its distinctively long mouth is said to be harder than diamonds. Could the Ultra Beast also use it to attack?
UB-02 Beauty: Its narrow, graceful legs allow it to accelerate with such explosive speed that people claim it can dodge lightning! It is said that any Pokémon that sees UB-02 Beauty, regardless of its own gender, will become infatuated with it and lose the will to battle. The exact reason for this reaction—whether it's an unidentified pheromone exuded by UB-02 Beauty or a hypnotic effect induced by its appearance—has not been determined.
There's still no telling what exactly these Ultra Beasts are or what role they're going to play in the new games. There's supposed to be another batch of new information on the games released next Tuesday, so we may find out something by then. For now, just stay tuned.
