>>43316852>ultra beasts that are not pokemon have their own worlds you can travel to so you can capture themThis is a good idea that needs more development time / resources to be expanded upon so that Ultra Desert (Pheromosa) isn't the only one with obstacles to get to the monster.
>an edgelord dragon turns into a handThis is bad because Eternatus is a pokemon from the game's timeline / universe despite having an outlandish design. It also turns into a literal hand. Not only does it turn into just a hand, the hand just floats there during the battle during some of its turns. Not only does the literal hand just do nothing sometimes, the fight with it can be won without the player doing anything and it's guaranteed to be captured.
Game Freak needs to stop making things fall out of the sky for no reason. The Ultra Beast portals were a phenomena that a group of scientists were aware of being possible, and then the Aether Foundation used that research to finally force a portal open which had a domino effect of bringing more to the islands. That's explainable. The player seeing a portal for no reason after leaving the lab coincidentally was unnecessary. Sword and Shield starting the game with a special item falling right in front of you coincidentally is a shoehorned way to allow a gimmick that they couldn't explain otherwise.
>>43316946The dragon associated with that region is a legendary that lives in the ozone layer. The alien monster is an alien monster that is not from the player's planet because it is an alien monster is given an in-game event and cutscene to make it a special encounter.
