Can be a random encounter, a boss, a miniboss, so long as it's something you're supposed to kill and you have rage issues against it, it qualifies! I dislike Diglett. I mean, I like it when it's IN MY PARTY, but Arena trap is a bitch when you're out of repels and just want to get through the damn area >.< Same with Wobbuffet Devils in Grandia II are not on my faves list; Ba-BOOM can go to hell with its OHKO-ness Oooh and Seymour in FFX. I mean, not only is he evil as a character, but all of his fights were insanely difficult for me! I'd realise the cutscene was leading up to a fight and just start weeping.
