>>30477026Zinnia confirms remakes are placed in different universes because there's a meteor in ORAS which Devon want to send to another universe. Zinnia reveals megaevolution is so powerful that cause distortions in reality that helps their clan observe a parallel world, "a world slightly different with some different pokemon and person, a world where the great war in Kalos never happened, where nobody knows about megaevolution and Hoenn is less advanced"
Before that, Steven's dad tell you how Devon corporation boosted the technology thanks to study the "infinite energy" (energy discovered investigating the Ultimate Weapon which ended the kalosian war), so basically RSE (also FRLG, HGSS, DPPt, BW and BW2) is placed in some universe where the war never happened and ORAS (also XY and SM) in the universe where the war broke out, the weapon was built, megaevolution was discovered and the world advanced a lot
Also in Battle Resort, Archie (in OmegaRuby) wonders about if is possible another universe where Team Aqua awakened Kyogre but Maxie (in AlphaSapphire) wonders about awakes Groudon.
The consensus is that there are 3 main universes
Retroverse
RGBY -> retroHoenn? -> GSC -> retroSinnoh? -> retroUnova? -> retroUnova2? -> retroKalos? -> retroAlola?
Modernverse
FRLG -> RSE -> HGSS -> DPPt -> BW -> BW2 -> modernKalos? -> modernAlola?
Megaverse
megaKanto -> ORAS -> megaJohto -> megaSinnoh -> megaUnova -> megaUnova2 -> XY -> SM
