My roundup from the Japanese trailer
- A new world is known as Ultra Hall and is accessible by riding Solgaleo/Lunala
- Necrozma stole the light from another new world known as Ultra Megalopolis, the world that I referred to earlier
- The mysterious organisation is known as "Ultra Recon Squad", with four main characters (in order they're shown in the above trailer): ダルス (Dulse), アマモ (Zossie), ミリン (Phyco), and シオニラ (Soliera, or salted leeks, who we saw in the earlier trailer)
- When you first meet them, they say "You're also not from Alola, you came from far away", suggesting that they are also not from Alola
- The second scene of dialog shows Dulse say "We only want to confirm one thing now"
- The third scene of dialog mentions some kind of aura and the effects of the Kahuna
- Soliera then tells Phyco to "investigate that guy" (i.e. battle) and she sends out this thing, known as UB Sticky (Adhesive in English), a poison type:
- UB Burst is revealed as fire/ghost
- UB Lay is revealed as rock/steel
- UB Burst's signature move びっくりヘッド (Mind Blown) is performed by exploding his own head, doing damage to himself of up to half his max HP (according to
this)
