I'd like to report a bug.
In Citadark Isle, the cipher peon Katie has a Rapidash that keeps using bounce. This means that rapidash never goes into the second portion of the move and keeps going up. At least I had Sky uppercut on my Blaziken, so I was able to go through this battle pretty easily, but this can be quite troublesome for players who don't bring/have any move that can counter pokemon that use bounce/fly.
