Oh, that thing. Heh.
This is more of a general pokemon question, but can hatched pokemon have their Hidden Abilities? A couple of the guides I looked up are sorta mum on the subject, and while I was looking up what level Rowlet evolves at I noticed that it has a hidden ability that sounds pretty neat. Of course, I doubt that any hordes of Rowlet are in the game and its too early for events to give them away...so how does one get these hidden abilities?
I can't find anything about changes to the breeding mechanics in SuMo. (aside from things like the nursery not increasing level, the poke pelago island) Unless they change things up (e.g. having a male of a different species with a HA cause a HA in the child), it looks like abilities go with the species (so a female 'mon with a HA has a good chance of passing it down, but a male/genderless 'mon can pass it down via a ditto).
Ability capsules (in gen 6, anyway) only allowed swapping between alternative non-hidden abilities (e.g. swap between delibird's vital spirit and hustle, but insomnia).
So...you need a pokemon with a Hidden Ability to even begin to hope to get another with a hidden ability?
That's a little lame. Also seems to make getting starters with HAs almost impossible unless you can just randomly get one at the start. Or hack.
