My current game is Atlantica Online and I'm still a bit at the beginning of the game. So far, the hardest boss I've encountered is the Mutated Tree. It was probably because I wasn't really ready for the fight but it took a lot of effort for me to defeat it. 3 out of 5 of my mercenaries died from the battle!

How about you guys? Hardest boss fight?

The Beast from AO as raid boss, for team encounter the Albtraum keeper also from AO =p

The lineage 2 Earth dragon, can't remember its name, but its freaking huge.

Took the entire server apparently when they did manage to kill it.

The preCU Meatlump King in SWG.

Fippy Darkpaw EQ1, he was mean I say!

He even announced his presence!

Ah, shoot. You beat me to it.

my real life employer, man is he mean, big and has the  permanent "anger" buff

i would have to say in GW (the cathedral of flames dungeon) in HardMode 1 player 3 heroes 4 henchies the big worm boss at the end

from my personal experience when i was a pre-BC guild Main Tank in WoW, would have to be the first 2 bosses in BWL, Kiting with Razorgore was a bitch, and Vaelestraz pounding the living shit out of then killing your Main Tank instantly every 30 seconds while AOEing your entire 40-man raid, 2 minute fight of doom :p.

DAoC, Hibernia's Dragon mob, Cuuldurach. First time we tried this we needed about 3-4 full groups, and even then there were countless rezzes.

I would say Trakanon right after Kunark was released in EQ.  The encounter itself wasn't that difficult, but getting to him before every other guild on the server was.   This race through OS was brutal, but a lot of fun.

"Pookie"  the White Rabbit from AC 1 before everyone started hitting max level with their characters 

If you even just tried to assess his Stats and Level when walking by his cave he would smite you to death

Ask those guys over at FFXI who did that 18-hour non-stop bossfight and still couldn't beat him.

I was thinking the same thing... Pandemonium Warden from FFXI is the hardest boss that I know of in MMOs.

Personally, it would be General Drakkisath from UBS in WoW. Before they made that into a 10-man raid and everyone was decked out in T1-3 gear that is. The respawn rate meant that, assuming you were lucky enough to have a warlock and could get a soulstone, you'd have two tries on him before having to start all over again. If even one person messed up... splat. If even one person wasn't hugging the wall and accidently pulled him from 30 yards away... splat. It was fun, but very difficult.

Come on, Mutated Tree was easy. Go on level 40+ you'll see that even mobs give you a hard time solo. I suggest you doing that one in a party. I guess you can...

MU - Not too much hard bosses except Kundun and Balgass. Others can be beaten to a pulp by agi BKs.

Cabal - Pretty much hogged them all using my Archer. Had a hard time in Pontus though. If the mobs are all over you, you'll pretty much die if you don't have a party.

So in the end, I still love offline RPG bosses. Once you kill them, then the game ends. You don't have to expect a random drop that shows up once in a while. MMO's are fun though once you look pimped up.

For the time, one that comes to mind is the Apocalypse encounter in DAoC; Albion's Shrouded Isles' dungeon Caer Sidi I think it was called. Four Horsemen and then Apocalypse, I think the first time our alliance brought twice as many people as it normally took us to take down the realm dragon, and wiped on the first Horseman.

That giant worm, Behemoth, at the bottom of Darkness Falls was a bit much as well for the day.

 

Sleeper in EQ1.

Ah the good old days of Rallozek before Sony nerfed it into another carebear server.

Bosses with a billion health points and AoE damage the entire raid for half health every few seconds arent "hard" they are just "stupid".

Very few bosses are difficult because of advanced strategies and tactics.

damn beat me too it

The damn small deers in EQ2, no matter how many you kill or what level you are, or where you are, there is always another small deer ready to rip you a new one.

Venge Sunsoar

C'thun from World of warcraft.  Ahn Quiraj 40 man raid dungeon.  The boss required everyone to stay 10 feet from each other and follow a specific pattern.  If somone didnt do their job, about 3 to 5 people around them would die.  In WoW, the only rez you could do during combat was on a 30 minute timer for only druids.  So dying was not an option.

On top of all that tentacles would pop out of the gorund and knock people out of their formation, increasing their chances of instant death.  This boss was not about healing through heavy hits, it was all about dodging attacks.  If you didn't dodge one attack, you died.

The boss battle itself takes about 20 - 30 mniutes to complete with multiple stages in combat.

Pandemonium Warden.
