>>40673180You already have something like this "gigantamax factor" in Greninja and his unique Megaevolution without stones (even Rayquaza needs a keystone at least, but not Greninja) and that Greninja can't breed and it's treated as a completely different mon in the game's data, but it makes sense in this case precisely because this Greninja has no evolutionary "relatives", no pokemon can evolve into this Greninja and this Greninja can't evolve into other pokemon, but if you can get your own Charmander (not Charizard, Charmander) with the gigantamax factor I guess it's gonna be a hidden value some pokemon have, you should be able to pass this gene by breeding
