You want a story eh? One that is so insane that nothing compares to it? Well I don't have anything that great, but this one is still good.
I was not a part of it, but I know of it. So there's an MMO called EverQuest, and it had a boss called Kerafyrm. Kerafyrm was not meant to be beaten by players, but let's hold off on that for now. So to spawn this boss, you had to kill 4 dragons to get him to spawn (I'm not sure if they had to be killed all round the same time or one at a time) and then the battle starts. Well, he was not meant to be beaten, so the Devs made it so he had a death touch effect, if he hit you then you would die no matter what. But is that going to stop anyone? No, so one guild assembled 180 players from both inside and outside the guild to take this guy down. Then more people joined up with their guilds, and we end up with so many people that there isn't probably anyone who counted it. There's just one problem, Kerafyrm is immune to spells save two, and those two aren't going to kill him anytime soon. So you have a lot of people running at this dragon with 250 Million HP (Most bosses only have 2 Million in EverQuest at this point), and he's destroying people, so how is this going to work? Well the group was mostly non-spell users for damage, and a LOT of characters who can revive and the plan was to just keep running at him until he dies. So people begin fighting this thing at it's going okay, 3 hours or so in and he's about down to 26% health. Then the devs come in, and they aren't happy. They despawn the boss right then and there and then claim that it was because they feared people weren't fighting him legitimately. They obviously didn't get it, because this wasn't going to stop us gamers and our insatiable bloodlust. The next day, there Kerafyrm was, ready to be fought again, and guess what? The crazy SOB's did it, another 3 hours and it was dead.
So I feel like this isn't some lame story, if I may be so bold. If you want, below is a link to a video on YouTube with footage of the fight (excuse the quality, this is 8 years ago). Yeah there's some lame song in the background, but this is 2007 and therefore this sort of thing is to be expected.
