/vp/, I've got a problem with Omega Ruby. For some reason, at the start of battle, my Swampert shakes. Occasionally, it'll say something along the lines of "It's feeling a bit out of it". It also gets boosted experience. At first I thought it was pokerus, but I've been to the Pokemon Center dozen of times since it started, and no pokerus. My friend thinks it's something to do with friendship, but I'm not sure since none of my other Pokemon do it. Does anyone know what would cause this?

Sorry, I don't have any screenshots of this.
