>>31921279Aw don't be so glum, Anon! They've changed Hidden Abilities before. Wouldn't be surprised if they did it en masse at some point.
They could get Bulletproof Heatproof and Soundproof, although I don't know who would get which. And I'm not sure the similar names are there in japanese.
Otherwise Solid Rock would do wonders for Regirock, and, well, I'm sure there's something for the other two. Regice in particular needs something cool.
Plus it's not out of the question they might all one day receive a Recover clone. Being they're organic robots, Recover itself already kinda makes sense.
