FF1: Lich 1 -- I generally try to push my way through the early game as quickly as possible and Lich is always a bit of a stressful fight after pushing through the Earth Cave at a low level, which I love him for. Doesn't usually kill me, but sometimes man, sometimes that first turn ICE 2 REALLY gets me down.

FF2: Borghen 2 -- Someone in hell hated him enough to stuff his corpse in a box, and that is funny to me. Too funny to not be my favorite boss in the game even.

FF3: Odin -- He's a great first bonus boss find, especially when he decides to horribly murder you. I dig it.

FF4: Plague Horror -- I love the idea of this boss, even if he is super easy.

FF5: Shinryu -- Not many things in this series are better than opening a random treasure box at the end of the game and instantly dying to a tidal wave. Love it.

FF6: Uhhh . . . probably Ultima Weapon. I generally play the game low level without espers and he is a hell of a fight when almost everything he does can kill a character. He really keeps you on your toes and I almost always look forward to the fight.

FF7: Lost Number, for the reason Shopkeeper mentioned above.

FF8: X-ATM. I love everything about it: trying to dodge it, trying to fight it, watching it get machinegunned down. All of it! 10/10, best mech spider boss, would fight again.

FF9: Ozma. I may not like unlocking the fight, but I do like the fight itself, especially the quirks of its ATB. Also love that whole sometimes it party wipes me and I can't do anything about it thing.

FFX: Ugh . . . Nemesis, maybe?

FF12: Me and my habit of constantly attacking Wild Saurions.
