We’re down to our last two Ultra Beasts: Stakataka and Blacephalon, who were added to the roster only in Ultra Moon and Ultra Sun (respectively).  We don’t know as much about them as we do about all the others, because we never see their homeworlds.  All the original Ultra Beasts, whom we first met in Alola in Sun and Moon, are encountered in Ultra Smoon by travelling through Ultra Space to their own worlds (while Poipole is involved in the story of the Ultra Recon Squad, and gets a major supporting role in the anime).  These two, we only ever meet in Alola, and we also get no information about them from Wicke, who is otherwise a fount of interesting (if occasionally dubious) intelligence.  As a result, there’s more I’d like to know about Stakataka that I just don’t, like what kind of ecosystem produces a creature like this, and how it behaves in its natural habitat – things that, for normal Pokémon, we tend to learn as a matter of course.  But we have the Pokédex, we have the design, we have Stakataka’s in-game types, stats and mechanics, and we have the anime episode it stars in, so let’s take a look and see what we can do.
