Hardest boss in video game history

[Caraway]

EverQuest: Kerafyrm, The Sleeper. It took over 180 people at the time of the first kill, many people lost several levels, took over 3 hours.

And they won with an exploit to boot. Pretty sure that event wasn't supposed to be completed though. And from what I heard it ticked a lot of people off because it made the event before it go away.

I'd say you're probably going to see a lot of "hardest bosses" from the 8 and 16bit eras of gaming. Whether it's due to game glitches making it difficult or just plain old difficulty you won't see stuff that hard again unless it's a majorly niche title.

The hardest fight that I can recall for me though was in Valkyrie Profile for the PSX. I don't recall the name of the boss but it involved going back in time to a city's past to find out why it went apocalypse. The boss fight you have to go up against there is very tough if you didn't expect it as he dropped a very powerful AE on your party very frequently.

It was pretty much the biggest zergfest of all time. Clerics pretty much sat there spamming res from their Epics. There was no exploit, but he did bug out and despawn at 25%. GMs were called, they agreed it was a bug, so Sony agreed to reset the even and posted an apology. Sleeper can only be awoken once ever, per server. Can never spawn on that server again.

I was lucky to be logged in when he was woken on my server when I played during that expansion.
