So I just caught a shiny Noibat in the Friend Safari. I rushed to see its nature and ability, and to my chagrin, it had an Impish nature and its Hidden Ability, Telepathy. Probably the worst possible combo. Can I still salvage him and use him as a Physical Noivern?
Just no, it will never work, go get another one, burn it in fire. Its Attack stat is aweful, its movepool is terrible and that ability is usless. It wont work, dont use it.
