>>57769038I'm not sure if you're saying that they're considered gods in the GBA and Gamecube games or if you're including ORAS as a part of what you consider to be gen 3, either way, they are not called deities in RSE, not even by those that revere them, therefor, they are no more godly than Ho-Oh or Lugia were at the time.
Ho-Oh has retroactively been made more godly as a result of Arceus and the Sinjoh Ruins being given a connection to the Ruins of Alph and the Unown, which previously were only associated with the gen 1 fossils, the beast trio and Ho-Oh itself.
