>>34074592> Is there any explanation why they are called "Z"-movesIn-universe? No idea but the name is supposed to be based on "zenryoku" ("full power" in japanese)
Zenryoku waza -> Move at full power
>How did the crystals get to AlolaAccording to Ultramegalopolis' characters, time ago when Necrozma still had its true power its light infused stuff with its power (they basically used it as energy source) and they theorize that such a powerful light must have passed through the wormholes rained down throughout the Alola region. So trial sites are places infused by Z-Power energy (Necrozma's) where powerful (totem) pokemon live in. Both Z auras and Z crystals are Necrozma's light... now, we already know for SM that the Tapu got their Z crystal from Solgaleo/Lunala so I guess at the end Z Power is Solgaleo, Lunala AND Necrozma light energy, just like megastones were created by Xerneas, Yveltal or Zygarde nature energy in Kalos. That's according to SM and USUM book, but the Ultra Squad says it was "the Blinding One" (how they call Necrozma) who fought the Tapu in the Tapu Village.
>Why does Dexio say that Zygarde is in Alola "again"?I mean he already said that in SM, this time is the same but he also mentions the UBs.
