Another new detail shown during the release of Kommo-o's New Z-Move was that of a mysterious wormhole on The Alola Region Map. This ominous vortex is seen just north of Ula'Ula Island, but not much more is known about it outside of it holding many secrets.
Many fans speculate this wormhole leads to none other than Ultra Space, a parallel world where time and space otherwise have no barring (much like the Distortion World of the Sinnoh Region). However, others believe this could be the home to none other than the mysterious Pokemon known as Necrozma (the same that looks to play a much bigger role than in Pokemon Sun & Moon).
