Notes:

CHECK No. 1: SATOSHI
Satoshi has fully cleared the Alola region's Island Pilgrimage, and has mastered numerous Z-Moves as well. He's also aiming to win the tournament, and his capabilities are top class!
PIKACHU: Satoshi's best partner, who has made its way through lots of battles alongside him!
MOKUROH: It sleeps all the time, but it really is a gutsy Pokémon that truly delivers when it counts!
LUGARUGAN (DUSK FORM): Trainer hard with Satoshi in order to become a strong Pokémon!
NYAHEAT: Competes in terms of strength with Lugarugan, whom it sees as its rival.
MELTAN: It's tiny, and its true capabilities are unknown. Its Flash Cannon is super powerful!

Z-MOVES SATOSHI CAN USE:
ULTRA DASH ATTACK: Mokuroh, Pikachu, etc
WORLD'S END FALL: Lugarugan (Dusk Form)
SPARKING GIGAVOLT: Pikachu
BLOOM SHINE EXTRA: Mokuroh
RADIAL EDGE STORM: Lugarugan (Dusk Form)
TRANCENDENT SCREW BARRAGE: Pikachu

CHECK No. 2: KAKI
A skilled Trainer who has been able to use Z-Moves since before he met Satoshi. Is there a chance he and Satoshi will have their rival showdown in the Pokémon League finals?!
BAKUGAMES: Fights with super powerful Fire moves! Cares a lot about its friends and companions.
GARAGARA (ALOLAN FORM): An extremely sore loser that has a one-sided rivalry with Bakugames.

Z-MOVES KAKI CAN USE:
DYNAMIC FULL FLAME: Bakugames, Garagara and Lizardon
FINAL DIVE CRASH: Lizardon

CHECK No. 3: MĀMANE
His partners are two Electric type Pokémon. Will he be able to use his calculation skills to win his way through the Pokémon League, which is filled with tough opponents for him?!
TOGEDEMARU: We expect it to give us a surprising (!?) show at the league with its spiky body and its Electric type moves!
KUWAGANNON: The evolved form of the Dendimushi he got from Satoshi!

HE CAN USE Z-MOVES AS WELL?
HE'LL OBTAIN A BUG-Z?!
Believe it or not, the first prize in the Kuwagannon Race is a Bug-Z! Make sure to keep an eye out for what Z-Move he'll become able to use!
