Paradox Jiggly doesn't evolve, no. All paradox mons are single stage; not entirely sure how their stats will work bc at this point i'm left confused by what khu has said.So what are the chances Paradox Jigglypuff evolves into Paradox Wigglytuff? I'm assuming this is essentially like Gigantamax Pikachu or Eevee in that they cannot evolve.
Will Paradox types be breedable or just catchable? Sounds like catchable only. Which makes me wonder if regular versions will be available that can be bred so we can breed a regular Foongus to get a regular Amoonguss. Or will the regular versions of these Paradox Pokemon be unavailable?
And from what we've seen so far, most "regular" versions of the Paradoxes have appeared in trailers already - Jigglypuff, Magnemite/zone, Tyranitar, Salamence, Hydreigon, Donphan, Gallade and Hariyama have all been featured in trailers. Pretty safe to assume the rest of the "base" mons will be here too
