The Pokemon Company has released a new trailer for Pokemon Ultra Sun and Ultra Moon.

Ultra Necrozma, a secret form of Necrozma which activates after it uses Ultra Burst, and UB Adhesive’s evolution, UB Stinger, are revealed in the trailer.

Check it out below.

• Ultra Necrozma Form: A previously unknown Form has been discovered for Necrozma after it uses Ultra Burst – Ultra Necrozma, which emerges from a blinding light to take the shape of a dragon! Ultra Necrozma is a Psychic/Dragon Type Pokémon with a new Z-Move called “Light That Burns the Sky” (if Photon Geyser is learned), which gathers together light energy until it can accumulate no more and unleashes it all. Ultra Necrozma also gains a unique new Ability called Neuroforce, which boosts damage dealt whenever it uses a super-effective move on an opponent, amplifying any of Necrozma’s powerful moves learned such as Photon Geyser, Sunsteel Strike, and Moongeist Beam!

• New Ultra Beast Evolution: The Ultra Beast Poipole, a.k.a. UB Adhesive, evolves into the Ultra Beast Naganadel, a.k.a. UB Stinger, marking the first time that any UB has been found to evolve! Naganadel is a Poison/Dragon Type Pokémon that gains the Beast Boost Ability and can battle with powerful Dragon Type moves, including Dragon Pulse.
