Boldore mostly because of Sturdy.
Also, Watchog is pretty annoying with Hypnosis/Super Fang. And Tranquill with the Detect combo.
But I got really annoyed with double wild battles with two Herdier and both having Intimidiate.
EDIT: Also, Foongus or Amoongus with Effect Spore. Foongus ALWAYS seems to put my guys to sleep where as Amoongus usually paralyzes, if not poisons.
Pixel Art can be fun.
