I'm specifically interested in regards to Alchemists and Doppelganger Simulacra, but it matters for all Simulacra.
The text for the Simulacrum spell states it creates a creature with half the levels or HD of the creature the Simulacrum is made from, with the feats/abilities/etc appropriate for their HD. By RAW, this does not affect Mythic Tiers or Ranks, and they would keep all their mythic powers. Yes, I'm not arguing RAW, but this spell was not designed with Mythic in mind. This still seems fitting to me as a rules question, if not to ask what the rule is, then to ask what the rule should be (and to Paizo, that a ruling be made).
If mythic power is supposed to be rare and difficult to obtain, one could argue that a copy of a mythic creature should have no mythic power, if you can copy it at all. Or maybe the Simulacrum spell can get around that, because its not actually creating a mythic creature, just creating a shadow copy of one. Even then, though, it doesn't seem to me like it should have all the mythic power, just half. Could be a mythic version of the simulacrum spell that can copy mythic creatures, too.
If it doesn't copy mythic power, though, what of the Alchemist's Doppelganger Simulacrums? Would they all be completely lacking the Alchemist's mythic power?
So, I guess there are two questions.
1. How should the Simulacrum spells interact with mythic creatures?
2. Should it work differently for Alchemist's Doppelgangers?
