"Stakataka's and Blacephalon's Ultra Spaces: what could they be like?"

So, as probably most of you already know, In Ultra Sun and Ultra Moon, we finally got a look at the home worlds of the Ultra Beasts, besides Nihilego, who's we saw in the original Sun and Moon. Buzzwole has Ultra Jungle, Xurkitree has Ultra Plant, and so-on and so forth.However, we never got to explore the worlds of the two newest Ultra Beasts, introduced in USUM (disregarding Poipole because we visit its world): Stakataka and Blacephalon. Rather than being encountered in Ultra Space like the others, we get to battle them in Poni Plains after the main story, instead. Thus, the worlds of those two have never been seen.So, here, I'd like to ask: What do you think Stakataka and Blacephalon's worlds look like? What kind of environment would they live in? Personally, I imagine Stakataka's world as a frozen wasteland where Stakataka wakes up occasionally, only to move. I can't think of one for Blacephalon, though... Either way, Discuss, theorize, share ideas and be creative! via /r/pokemon http://ift.tt/2ApqmXt
