YOU WANT SOME LEAKS
I'LL GIVE YOU SOME FUCKING LEAKS
Part of the Post Game of USUM is that you're contacted by the Aether foundation for your good deeds and granted access to the Aether foundation nature preserves scattered around the world. Each preserve is a different sort of biome in which you can encounter Pokemon not found in Alola. The types of biomes are Savannah, Tundra (which cycles between completely frozen to spring bloom based on month), a Deciduous forest (cycling between the four seasons, also functioning as place where you can finally get the Sawsbuck/Deerling forms again), a mountain range, and a specially designed habitat meant to simulate an empty human settlement for attraction Pokemon that are have adopted and evolved around human society)
US/UM will be the first games ever where between the two versions every Pokemon in the Pokedex is catchable without needing to transfer, as certain days of the year will trigger event flags which will cause a Legendary Pokemon to spawn in a one of the biomes. The one catch is that you're only allowed to use "Aether balls" to catch Pokemon in these preserves, which have a catch rate of an Ultra Ball and you're given only 50 a day and you must return any unused ones the next day before they'll refill your stalk. Don't think you can cheat by giving your Pokemon in the PC Aether balls to hold, the game checks for that.
