Fan Casting Spinoff Game Characters in Pokemon Masters

If the characters from the various Pokemon spinoff games appeared in Pokemon Masters, who should portray them? Professional VAs only, English voice actors only (Japanese will be a separate fancast), no celebrities. FOR ADDING ROLES: Only suggest human characters (this means spinoffs with no humans like PMD, Rumble, etc are technically off-limits), try to stick to the Masters rule of "Protags, Rivals, Gym Leaders/Elite Four/Champions or equivalent, main villains and prominent NPCs" only for role additions.
