1. That supid Gas Masked guy at the end of Advanced Wars 1 (GBA) He cheats with that stupid meteor strike!

2. Mortal Kombat 3 (SNES) I was young back then and I never tried recently... I wonder if I could now?

to me the whole mission counts as a boss epilogue on veteran COD4

Dark Coud's final boss, The Dark Genie.
He was very hard. Rewind back to when I was trying the game, and I had managed to get to him after much MUCH labour. And he PWNED. MY. ARSE. Fast forward two years, and I STILL haven't beaten him.

Just about any King of Fighters game ever seems to have a last boss that reads your inputs and makes it impossible to deal any sort of damage whatsoever to it without punishing you with cheap shit that takes 2/3 of your health bar.

Especially KOFs 99 and 2002.

Never beat the singe player modes in those.

The Final boss of Half life opposing force. Around the time I had to whip out my barnacle gun to jump a gap created by bridges falling of their own accord while the lizard alien thing patiently waited for my safe arrival, I turned the game off. So Lame.

The final boss of Final Fantasy I for GBA. I plan on getting back to it eventually, but that could be awhile.

So very true! I've never beat them without continuing with the "start boss with 1/3 health" option.

By the time I got to the last boss in Parasite Eve 2 I'd run out of most of my ammo and health and I couldn't be bothered going right back and preserving them. In summary, I gave up.

I never got around to beating the last boss in Legacy of Kain: Defiance, It's not that he was impossibly hard, it's just that I had to return it to a friend of mine 'cause he had to return it to someone else; never got that game again...

the final boss in FF2
right when i got to him i saved. the next day i found out that my little brother accidently saved over my file

The Boss on MGS 3 (hard I think) I was using cheats because it made me feel like a big man and then when I got to her I got bored and stopped then the next day when I went back I had lost my Action Replay Max disc so could not use any cheats and have got beaten every time since.

The last boss of Advance Wars was just a war of atriation. ;)

I never finished Psychonauts since tent part of the Meat Circus was to hard. Since I doubt the ending is in any way suprising I probably didn't miss much.

Green Eye, well i just got lazy after a few trys and gave up...

I never beat Metroid Prime 2's final boss, but that's mostly because I could only get in two attempts before my memory card was wiped. That was tragic.

Also, I never beat Vergil in DMC3. I never beat DMC4's last boss either, but that was more a matter of "I'm sick of this freaking game" than "this boss is too hard."

ive had that same problem, except it was with the orginal breath of fire and my sister didnt delete the file on accident.

I think my Half-Life game was buggy so no matter what I did to the last boss, nothing happened. Fought him for hours, went to gameFAQs, BUT HE WOULDN'T DIE.

In Sonic Adventure for the Dreamcast, *Cough*, I never beat the part where Chaos (the water monster) floods the city or something and you have to run around at light speed and he can tell where you're going and crush you to death. Not fun.

Final Boss of FF11

Yes! Thank you! KOF has the WORST bosses ever! They have unblockable attacks, unending combos, and unlimited special combo attacks that they can summon at will. The difficulty curve of any KOF game goes from logical progression to brick wall inside of 15 seconds!

The Elite Four on my Pokemon FireRed game. The Eight Gym is easy as hell, then the Elite Four's weakest Pokemon are about 15 levels higher, no way am I doing that much training to not really win.

sephiroth(did i spell that right?)from ff7i finally fought my way through that crater and defeat all his forms but when i got to his 1winged angel form, he pwned me.the battle lasted about an hour,but then he started spamming his supernova thing and he finally killed me.Before anyone calls me a noob i fought him at lvl40.looking back on it its a wondor i ever got to him in the first place

The final boss of DMC2. It was just a ridiculously hard fight. It kept shooting crap left and right and spamming crap from the earlier bosses. Eventually I said "F*** This Sh**!!" and sent it back.

ugh... this is embarassing... Clock-la (I think) from Sly Cooper 2. Don't know if it's the fact that I played that game or haven't beaten the boss...

Technically every Madden game I've ever played; never got to the super bowl (or finished a season for that matter).

The elite four in pokemen red, blue, and ruby. Just didn't put in the time.

I-No from Guilty Gear. I mean, Jesus fucking Christ, that bitch was a cheater! One of the reasons I hate facing computer opponents in fighting games is because they are able to execute combos, counters and guards that no human could possibly string together.

*sighs*...GLaDOS...I'm going to go cry now.

Leave me to my shame!

Even though it's supposedly one of the easiest battles ever, I left on vacation all those years ago before beating Nihilanth in HL. Just never got back to it...

You deserve that shame, sir! Go beat that game right now!

Raam from Gears. I don't know why. I even went to the FAQs and everything. I was playing it right, but I just couldn't hit him enough times before he drove me into the flocks of bats. Overall, I was unhappy with fighting him anyway. After working through all of the game where the type of weapon you use was secondary to how you used it, being forced to use explosive arrows and the sniper rifle instead of your trusty assault rifle felt like a cop out.

1v1 40? wow bold move there. I always follow my/the rule of 60, never face the final boss of any rpg unless you are at least lvl 60, its like the safe zone or something, never has failed me much.

As for me, I never got around to beating the last mission/boss of Bahamut Lagoon, God damn was that an awesome game but every time i would get close to the end, I would run into comp troubles and lose the save file. *sighs* some day Alexander, some day i will kick your ass.

Pool of Radiance: Ruins of Myth Drannor. First you fight an insanely powerfull Sorceress (although I think you get recharged after that fight) then you immediately face an overpowered as can be dracolich.

Warhammer: Dark Omen. That bloody arse has to be cheating! You can only use 10 regiments while I know I have seen that jerk with as many as 14 regiments! How are you supposed to beat that, considering the dreadlord can probably take on 3-4 regiments by himself anyways!

You must get that ending song! You must! For the love of God!!! Beat that Game!!!

Synangel:
Final Boss of FF11

18 hours of play and you couldn't beat him, correct?

Lou in Guitar Hero III on expert.

I came close once... but he just used the cheap "lefty switch" on me and I DIED.
