What boss battle just plain annoys you, be it so much health, insta-kill moves, or just plain a long unskippable cutscene and then it is the toughest fight ever.
For me, Konstantin Brayko from Alpha Protocol
All the other bosses were easier, but him, I died 6 times on easy thanks to him. He first guns you down with an SMG so I basically closed the gap and decided to try to take him on in hand to hand....bad move, he pulled out a pair of knives then cut me up like a turky.
So after i died I used a combo of explosives and assault rifle to take him down a bit...and then he snorted some drugs...and then chased me around the room and as Yahtzee put it "Like Benny Fucking Hill"
Let me just tell ya, it was a pain not to shoot the guy in the cutscene after I beat him, but I was trying to get the achievment to not shoot every important person...but next playthrough...oh yeah he is dead
