What are some new abilities for older Pokemon that just make sense but for whatever reason aren't a thing? This was a decently popular thread so let's have another crack at it. This time you can throw out other things as well, not just abilities.

Some other ideas I've had:

>Bellossom not getting Dancer. The whole Oddish line still only has 1 ability and a HA each
>Carnivine not getting Strong Jaw or some unique Bug type Sap Sipper
>Dusknoir line not getting some sort of Ghost absorbing Lightning Rod ability
