How did my Nidoking have its ability changed from its Hidden Ability to Rivalry?

Jun. 27, 2016

I have a serious problem. My nidoran-M had hustle, its hidden ability. when it evolved into nidorino, it now has rivalry. Finally, I gave it a moon stone, and kept rivalry when it evolved. How is this possible? the Nidoking I bred with had sheer force and an everstone. I know it’s a 50% chance to keep its HA, but it had the ability. Plz help.

I’m sorry, but the only possible answer is that you must have accidentally switched it for another one while breeding. Or you’ve hacked the game so much that it bugged out for some weird reason, which I highly doubt.

There are cases where non hidden abilities are changed when crossing generations, but it never affected hidden abilities. Good luck on getting back that sheer force nidoking!
