The Curious Case of HIDDEN Hidden Abilities

[Dragonstrike]

Oh yeah! I completely forgot that Tonemy didn't have an HA until evolving! That goes a long way towards explaining how a lineage without an HA could inherit the ability to pass on an HA even when none of them have one.

Though it still seems bizarre that that's the case, yet shiny mons without HAs caught with the Pokeradar aren't classified as having HAs to breed with... Unless... Come to think of it, I've only tested it with Duplicat. Maybe it's possible to catch a shiny mon with the pokeradar that doesn't have an HA like Mareep and have it work? Or maybe it really is only possible to get a mon capable of breeding HAs despite neither it nor its evolutions having one via breeding...

It's not like it's useful tactically or anything, but it is curious.

I'm not sure about Mareep, since I haven't tested that one either (Mareep usually does have a HA in the canon games, though I think the idea behind not giving it a HA in this fan game was so Neopunk and Praseopunk were the only pokemon with Plus/Minus in Uranium).

As far as I'm aware, however, Duplicat is the only pokemon that can't pass a HA trait at all, and I'm not sure if it's intended or a bug.  If Mareep can't pass HAs either when you catch a shiny one via a Radar chain, it might be a bug, I guess?  From what I've heard, Duplicats Abilities aren't quite coded the same way as other pokemon's are, but I don't know if other pokemon with no HAs suffer from the same thing.

Obviously, that doesn't seem to be the case with the Tricwe you were breeding, though, which might indicate that the Duplicat not being able to pass HAs thing might be intended. 

This might need more testing (or dev confirmation), but testing it would take a lot of time, so nobody's done that yet to my knowledge.  *shrug*
