Definitely confuse, its so annoying how when you use it, they will never attack themselves, but when they use it in you, spend 4 turns straight killing yourself and your partners. Paralysis and infatuate are also annoying on major battles, but confuse is defi9nitely the worst for all the battles in the game.

Wow, lots of people hate confusion..

In my opinion badly poison is the worst. After every turn the poison does more damage. But because I can't choose this one. I think it is confusion. It happened more than ones that my Pokémon fainted because it attacked itself.

  Okay there are a lot of Pokémon moves that are very annoying but I chose being confused because it lasts forever when it is only supposed to for a turn or so and my Pokémon damage themselves and then end up fainting because of the lame confusion move. So I really dislike the move when it is being used on me, but whenever I try to use it on another Pokémon it never works and they are unaffected by it. I also hat it when the Pokémon uses a move that puts my Pokémon to rest for several turns and I can't do anything and then I try to swap out Pokémon and the same thing happens and they keep using that move. I also hate it when they spam moves that recover there hp, I find rest to be very annoying because they get all of their hp back and when you attack them and almost beat them they wake up and use it again. Also recovery moves like solarbeam, recover and moonlight are very annoying recovery moves that they will spam like 20 times and never lose hp. The move protect is another annoying one as well because they will repetitively use it all the time.
