-Nihilego are rock jellyfish that evolve from natural crystals.
-Buzzwole are giant mosquitos with muscles. I can only assume they are fighting type because they have to break out of the rocks they develop in, that look like buzzwole flexing their muscles.
-Phermosa come from a world with pods, this one is obvious.
-Kartana develop from the buds that resemble them.
-Celesteela develop from the bamboo shoots seen in their pocket space.
-Xurkitree is also obvious in this regard.
So yeah, UBs kinda have to come from Pocket Spaces, as if there is an entire planet that has several environments where God Tier Pokemon are infinitely born that would be overkill. Also makes you wonder if these Pocket Dimensions all are within one giant Ultra Hib World or what not.
An Unown Ultra Space would be all kinda cool, and would be the only logical way to make em obtainable in game, because we are already 3 years without any Unown areas.
