Link, Toon Link, and (for some strange reason) Mario
Of course, this is only from a perspective of who is cheapest when the CPU uses them. CPU Link/Toon Link will always target the player character with that damn final smash of theirs, and i've found Mario to be a strangely frustrating CPU opponent, something that is unique to Brawl (he was never a problem before)

Monster Hunter: pissing me off since 2010.
