Idk about storywise, but what I want is an itrm much like the ability capsule. It's for hidden abilities. It can't change an ability to it's HA one, but it can change the HA to a norml one. Most HA's are really good, but a there are a few that are bad. Yanmega for example, and i hate Houndoom's HA. Who knows, it might happen.
