Emolga! It will randomly go back to it's PokeBall after an attack! I was using it in an Elite 4 battle and it went back to it's PokeBall and I about threw my DS across the room. I find all the really weak wild Pokemon in the beginning of the games really annoying too!
Smergal on Pokemon online because of how imature people can be some sleeping move then harden then well gess the third and final move the they send haha your pokemn are going to need therapy and disconnect it is so annoying how many people do it.
