Players have the opportunity to catch Dynamax Pokemon from the Galar region, but also from several different regions. On the other hand, it appears very cool. On the other hand, it may leave players scratching their heads as to how this is possible.
Ultra Wormholes were a significant part of the generation seven Sun and Moon games storyline and then expanded upon in the Ultra Sun and Moon games with the introduction of Necrozma, which is discovered to be responsible for the creation of the Alola region and has the capability to open Ultra Wormholes with ease.
Necrozma''s Ultra Sun and Moon pokedex entries reveal that it is awry as it rages around in search of light, which serves as its energy. Its apparently from another world. If it isn''t devouring light, impurities build up in it and on it, and Necrozma continues to darken and transition, as its pokedex entry suggests. That may explain how Ultra Beasts ended up in the Galar region, landing an Ultra Wormhole, and
Despite this, the scientist didn''t seem to be surprised. One possibility is that players in the postgame encounter encounter Mohn in the Poke Pelago, and in the postgame encounter for Sun and Moon Lusamine, he might have lost his memories when he went through the Ultra Wormhole a second time when the Galar scientists tried to return to Alola.
Mohn is missing in the Ultra Sun and Moon games, and Lusamine''s goal of trying to search for him remains the same in the post game. It is possible that the Galar scientists exchanged their opinions and provided them with a Beast Ball which they hand over to the player. Overall, it might be helpful to direct use and tie in Pokemon Sword and Shield with its predecessor, Pokemon Sun and Moon.
