What’s the hardest boss you’ve ever beat in a game

Sephiroth made it to number 3 on this guys list:

I would say some of the hardest bosses I've faced are in World of Warcraft.  There are so many to list and the crazy part was that you needed 30 – 40 people to work together to do it!  Some of the hardest bosses I never even attempted but the best one that I beat was Nefarion in Black Wing Lair.  I pick this guy because it required everyone to be focused and involved.  We had to learn and experiment with new strategies and the boss battle had like 5 stages.  We died so many times on him I lost count.  Probably spent close to 21 hours before we beat him and endless extra hours getting the gear and items needed.

What also made it tough was that he was the end boss of Black Wing Lair.  To get to him required 3-5 hours of killing other bosses while making our way through the Tower.  Keeping 30-40 people on task is annoying as hell.

Definitely Crying Wolf.. She wasnt hard, but it took me so long to find out what to do the first time i ever played the game. 

Radec in Killzone 2 on the hardest difficulty was very hard..

it took me a long time to beat this boss and he appered in 2 defferent games his name is…………………………………………………………Sephiroth this ass h*le has kick my ass on the ps2 Kingdom of hearts 2 and on the psp Final Fantasy 7 Crisis Core. In kingdom of heart if you beat him you get a keyblade that looks like clouds sword anyways every time i had him he pulls a trick out of his sleeves. i didnt have to beat him it was optional but i wanted the new keyblade and in ff7 cc  i have to fight him twice dame i have to put that game down for a week before i beat him ass h*le

sorry, no offense, but in ff7 sephiroth was pretty friggin' easy.  I got to him, killed him, loved the ending, and was disappointed with the difficulty until I realized he isn't the toughest guy in the game.  Go fight emerald and ruby weapon (ruby is by far the biggest pain in the ass enemy ever). 

I know there's worse, but off the top of my head, the most recent pain in the ass boss for me was the guy at the end of fracture.  I was barely motivated to finish that game, and he irritated the hell out of me.  However, my vote goes to Minion in Twisted Metal: Black.  He's not too bad once you realize to just drive in circles and shoot randomly until you finally whittle him down to nothing, but the fact that even one mistake and he flame throws the shit outta you and is just so immensely over powered and unfair is irritating as hell.
