The Curious Case of HIDDEN Hidden Abilities

[Dragonstrike]

Yup, breeding using at least one parent with an inherited HA trait results in the possibility of an offspring with a HA trait in Uranium, regardless of which parent has the trait (or what species they are).  Duplicat, unfortunately, cannot breed HAs itself at the time of writing due to not having any kind of HA at all, unlike other pokemon like Tonemy and S51 (which both only have HAs when fully evolved, though S51's is currently unobtainable)

I can also verify that HA Nupin is 'officially' released, but the only way to currently obtain one is from someone who already has it, as Duplicat has no HA at the time of writing for some reason (otherwise, no HAs would be unobtainable). Due to a set of unique circumstances, a breeder came into possession of a HA Gellin with Cody's trainer ID and got permission to trade its offspring to the community from the bigwigs, so nobody should get nailed for simply getting a HA Nupin via WT.
