JET FORCE GEMINI
Mizar

After you poor blood on the cartridge and an entire weekend getting all the damn ewoks you have to fight this.....this THING. I'm a pretty good gamer i'd say, most games arent so much of a challenge as they are seeing how long it will take to beat it, but DAMNIT, took me 4 hours to beat this guy, dying OVER AND OVER AND OVER.

Post your most difficult boss encounter, lets reminisce

Master Murai fron Ninja Gaiden, far, far too hard for a first level boss. The first fight with Alma held me for a few days too....

My girlfriend.

The final boss on Parasite Eve 2. I don't know if it boiled down to bad resource management throughout the game, but I burned through all my ammo on it, it didn't even look like dying and I had nothing left to use but harsh language. Needless to say that didn't work.

Easy. The End, from MGS3. I literally spent three hours fighting the bugger. I literally had to save, mid-fight, and come back the next day to finish him off. And one time, I was using my d-mike to search for him (didn't use the thermals), then clicked it off, and when I came back into third-person view, he was standing right on top of me. Literally. I still get chills thinking about it... (Then he shot me. In the head. Not fun...) Plus, I had the bright idea of trying to tranq him to death. So very worth it though, to get my hands on his tranquilizer sniper rifle...
Then again... I haven't fought The Sorrow yet. Though that'll probably be more awesome and mind-screwing than hard...

In the vein of "Natsu_Blaze," I choose another boss from MGS3, ironically called... come-on, you know.. "The Boss." Took me forever to beat her because I have this stupid obsession with never firing my weapon, so I kept trying to melee her to death. Eventually, I gave up, and used fire-arms. Made my life much easier, though i still had to try over and over like 9 times after that.

The Brute Chief with the hammer at the end of Halo 2 on legendary mode.

On the Legend of Zelda: oracle of Seasons for the Game Boy Colour was a boss that could best be described as a giant eye that jumps around the screen.

Well to beat this boss you needed to use your Magnet Gloves to push a giant spiked ball at mr Big Eye. This all sound fine and dandy except for the fact that the ball hurts you. Quite often I would be trying to push the ball at Mr Big Eye, miss then press A again to drag it pack to me but have my thumb on A for one millonth of a second to long and have the giant ball ram into me taking off some hearts. Very annoying.

Well eventualy I had gotten lucky enough to hit Mr Eye ball enough times to make him make his death noise, but instead of becoming a heart piece he transforms into many little Mr Eyeball's. If you don't kill all the midget Eyeballs with the metal ball of death then you have to start again and the eyeballs don't want to die from the metal ball of death so they run around very fast, making it hard to hit them and easy for you to get hit.

I kept my cool though and 200 deaths later I was able to get my piece of heart. I picked up this game a few months ago and played through it again. Well this boss, that had given me a month of suffering was now easy. Far too easy. I think killing him with only losing 4 hearts pissed me off more than losing to him 200 times.

Any of the bosses in Sonic the Hedgehog 2 for the Sega Game Gear. NOT the Genesis game, but the game for Sega's underrated portable system.

Majora without the Fierce Diety Mask. Its possible, but fucking hard.

And Gruntilda from Banjo-Kazooie. I just gave up.

He's insanely easy tobeat. Stand up, get shot, dig out the dart, and follow the red circle on your map in high camo. Bang Bang, and you got yourself the Mosin Nagrant and the Moss Camo. Pity its useless from then on.

And for TheSorrow, you need to remember how to access the reverse suicide pill after you are dead.

Almost any boss from Dragon Quest VIII. That game takes way more grinding than the Final Fantasy series.

mother fucking lou I played him on medium because I played medium since 1 and now playing on hard would be like asking me to jump off the empire state building and survive but that fucker expected me to play the devil went down to Georgia survive the most frustrating solo known to mankind and still survive with enough energy to beat his ass while using the mother fucking ORANGE button I'm sorry but when did medium get an orange button with out the difficulty up power up being used in battle. oh and I am not the fucking flash so don't expect me to be able to make my fingers move 30 miles a damn second.

Yet another good reason why Neversofts Guitar Hero Sucks. At this point I'm wondering if they did anything right.

Oh my God. That game was ridiculously hard. I think it was the main reason I did not play my Game Gear. I was so frustrated trying to play that and Cool Spot by lamplight. Argh!

The boss in Baten Kaitos Origins who I cannot name, for it is probably the game's biggest spoiler, who you fight in the battlefields of Atria. I'm just glad the game gives you unlimited chances to win the battle or else I'd never have finished the game.

That stupid tortoise boss in Shadow of the Colossus. It's not like you die very often when fighting it, but even when you figure out to stun it with the geysers, it's a bitch to try and make sure it's standing in just the right spot while hoping that a geyser will randomly decide to burst beneath it.

His name was Don, he managed the grocery store where I worked, and one day walked in and announced to the staff he'd decided he didn't need to take his meds any more. He then proceeded to rapid-cycle through 10 days of mania, two weeks of depression, and three weeks of normalcy, over and over. The strategy was pretty much a combo of stealth and defensive combat. He finally fired me in a fit of manic paranoia. I'm not sure if I beat that boss or he beat me, but I did make it to the next level.

The Guy in I Wanna Be The Guy

Basically the hardest boss of all time in one of the hardest games ever made. You have to dodge his rapid fire pistol which shoots bullets that take up almost a quarter of the screen, all whilst trying to make pixel perfect jumps to reflect them back at him, which fails if you are off by even half a second.

Then, once you think you've beaten him, he ends up with a second form that takes up half the screen, sets the floor on fire, shoots homing fire balls at you that follow you through walls, and only has one incredibly small weak point that you have to fire at, all whilst being chased around the screen by a huge laser of death that kills you if you pause for a fraction of a second.

Oh, and did I mention that if anything even remotely grazes you, your character explodes and you have to start the entire fight over again.

That one boss from the first Half-Life. I had no idea whether I was hurting it or not, I spent ours jumping around and shooting inside it's big head, but, nothing seemed to work, I even looked at a walkthrough.

There were some bosses from Ninja Gaiden (the xbox one.) that I remember if I made one small mistake...I was ****ing Dead...I still beat them after many frustrating tries though.

Also, DMC series has some real tough bosses, but, after playing a while, I end up getting really good at DMC so despite how epic - tough- or unfair a Boss fight is, I can still manage to get through it, and DMC usually has some AWESOME boss fights.

-and man, the Boss at the end of Tekken 5's "story mode" = Cheapest boss ever, ugh, it was just plain unfair what that guy could do, I really don't want to go into detail, it would turn into a huge rant.

facing 25 metal gears on european extreme on mgs2
was definately something i had to keep working at but i eventually did it :-)

Guilty Spark from Halo 3... Egad! He has SO much health and SO much firepower!

That was the hardest battle I have ever encountered in ANY game EVER!

Mizar WAS a bitch and three quarters, I'll admit.

In terms of suicide-inducing annoyance, however, I have to go with the Wiegraf/Velius fight in Chapter III of Final Fantasy Tactics (the PS1 one, not that crapfest on the GBA). Not having the good sense to look up ways to cheese him to death, I spent AGES trying to beat him, eventually restarting the game so I could level way the hell up before I tried to fight him.

Eventually my brother's friend came along and told me to just make an entire party of Lancers, as his doom magic couldn't hit my party if it was in the air. I was rather embarrassed. Then I looked online and I found the Chemist/Teleport thing, and I felt even dumber.

In Mass Effect, Saren was hard, but only because the game bugged out on me and I only had one squad member with whom to fight him. In Metroid Prime 2, I thought the Ing Emperor was pretty hard, as was the Omega Pirate from MP1.

(In spite of my babbling about 4 games, I think the hardest fight was Wiegraf/Velius. I just like to whine about other stuff.)

Wiegraf/Velius in Final Fantasy Tactics is up there.
I ended up having to go for pure luck of two ninjas dual-wielding maces that critical hitted with all hits and dealt the upper-end of their damage, because I didn't know about the manly strategy of yelling and accumulating until you're god. It took me a LOT of tries to actually beat him.
Then it turns out there are like fifty ways to cheese that game to hell and back and make it extremely, stupendously easy with that boss fight not even being a bump in the damn road. And here I was playing it normally. Boy did I feel dumb.

I'm going to have to say the Barbarian King in God of War 2, Titan Mode, is up there too.
God...I still have to figure out a way to dodge that stupid homing-instantkill-ghosts-that-cant-be-blocked attack.

Fighting The End the first time around in MGS3 was...an experience. It took me close to three hours, my sister sitting beside me all the time. (The moment we got MGS3, we ran to our PS2 and didn't leave it until the game was entirely completed, many hours later, in the middle of the night. It was awesome.) However, that wasn't as much HARD as it was TEDIOUS. Very much like fighting 25 metal gear RAYs in MGS2, only worse because of the pure annoyingness involved in fighting The End. You scout the area for ten full minutes trying to find him, before you see him for JUST a fraction of a second, and just as you're gonna fire...POW! You're on your back, and he's run off to somewhere else. Old asshole.
You bet your ass I ate that parrot when I found it, as REVENGE!

The Great and Mighty Poo (Conker's Bad Fur Day).

When he enters the last segment of the song, you have to make this suicidal leap that gets me every time. My roommate is the only one of my friends who could beat that guy, and only after many MANY hours of swearing at the screen and molesting the controller (not that way you sick bastard... He saves THAT way for Animal Crossing).

The first time I fought 2 tanks, immediately followed by an attack helicopter on Ninja Gaiden. The fact that you don't have a chance to go back and buy health between battles just adds to the pain. The first time I got past it all I forgot to go back and save, only to die immediately in the next area, that was annoying. I'm the only person I know to have smashed one of the original (massive) xbox controllers because of that one. I have to mention the final boss "battle" at the end of that evil,evil game. Essentially you have to fight a selection of the bosses from throughout the game one after the other,without dying before you face the final boss who, bizarrely enough, isn't too hard at all.

The creepy moth thing from Echos. It is not actualy hard, yet unless you know how to destroy it, you will waist hours fighting it.

Bosses from Lost Planet. Especially the giant earth worm.

Zero in Mega Man X2 if you don't collect all his body parts from the X-Hunters.

Ohh, I'm gonna have to say the two huge guys at the end of that pain in the arse chariot obstacle course in prince of persia: two thrones.

Bad enough that I used most of my sand getting through that effing obstacle course, but a boss fight right after? Rubbish.

The hardest boss i ever fought is probably Omega Weapon in Final Fantasy VII, took about 50+ minutes to beat him (alooooooong time for a boss on a game like that) and you had to have all u;r party under te hero drinks invinciblity effect to even fight him since every move he did 1 shotted all u;r characters for a insta-game over. That meant long hours even days gets lots of them, went through about 73 of them and almost all of my aura magic to beat him, good thing he was an optional boss.

While Omega was the hardest, one of the most annoying i fought was Yiazmat on FF12, the n00b had 50 million health and the max dmg u could do on it was 9999 a hit with anything (goes down to 6999 when he goes under 50%), so ofc it tooks ages (took me about 3+ hours of solid fighting to beat him) and ofc on 12 with the gambit system after about 20minutes ofthe fight u get bored and let it run itself, occasionally changing the party leader cuz he decided he was gonna do a 11 hit chain for 4k each hit (or the crushing low effect working on his melee [instant death]). Other then that he's really easy, until he goes down to about 5% then casts Reflectga on u;r party (and ofc u;r not really noticing cuz the fights gone on for over 2 hours and u;r doing something else) so so bastard in u;r team uses Restore on the group and it reflects back at Yaizmat to heal him, but does it do about 9999 healing like u'd think it would? OFC NOT it does the actual restore effect and puts the ucka back @ 100% health, completely wasting the 2 and a half hours it took to get him down to 5% in the first place, which i noticed all to late making it 7 hours 52 minutes before i actually killed him (not including the time it took to leave, restock on remedies and such). let me tell u;r pad and PS2 were flying that day <.<;

Dullahan in golden sun 2 with lvl 50 chars... "Go grind yourself retarded" befor you can finish him. (getting from lvl 50 -> 60 battling highest xp monsters takes months of nothing but grinding mosters)

Fusion dragon in golden sun 1... By going through the game at normal speed (not extreme amounts of grind required) gets your chars to lvl 32 - 35. Litterally hard as steel.

Not really a boss, but the temple level of Darwinia. (3 hours straight og nothing but killing vira)

Quake 4 the Makron... 20ft. tall, 15ft. wide, six legs, laser, grenade launcher, dark matter cannon, electronic testicle maulers, a-bombs - you name it, he pulled it out of his pocket and fired it at you.

The hardest boss/bosses I've ever to beat was Sephiroth from Kingdom Hearts I&II

Medieval 2:Total War.The Timurids. Full army, with over 5 units of Elephants, one of which has artillery, 2 units of rocket launchers, and crapload of elite cavalry. Very Hard Mode. No auto resolve. No artillery.

Making any kind of defensive formation is nigh on impossible, and don't even think about bringing any infatry, cause those fuckers can kill anything that isn't mounted in mere seconds. And the elephants are real buggers: In RTW, you atleast had incendiary pigs that could send them into a wild frenzy, but in MTW, you gotta kill them the old fashioned way. The only reason I beat them was because of an AI bug that caused their general to be in a unit of archers. And even after the battle, I had lost 3 full units of gold chevron lancers and had lost all of the 3 archers units I had used, and it cost over 15000 florins to retrain everything. The good news, however, was that after the battle, I had full control over all of northa asia, and only had the middle eastern and Italian nations to conquer.
