Question

Im trying to get a zubat which will eventually be a crobat but anyway I want both brave bird and hypnosis. Is that possible?

Answer 1

While it IS possible to get multiple breeding moves on the same pokemon, sometimes you can't.

In this case, you can NOT get Hypnosis and Brave bird on the same Zubat.
