Fuck me, here's the shortest version I can possibly give to fit in 10 years of this bullshit:
So the original setting is on an island, right? And you have these six tribes that each represent one of six elements. And they have wise leaders, and this one asshole who's trying to ruin things by infecting monsters on the island into attacking the villages. And this shit isn't like "oh boy, some wolves", it's like "villagers made of 12 lego pieces vs giant monsters made of 400 lego pieces". But then one villager calls these heroes who are made of 30 lego pieces in capsules, and they put themselves back together after all of their organic parts rotted, and they heal up, fight amnesia, and save everyone. They beat back the asshole, and collect masks of power, and so on.
Well, then they get their powers taken for a while, and end up fighting this super monster that has all sorts of powers and is a hybrid of other things, and one of the old leader guys shows up and turns invisible and gets the thing to kill itself because it's mad at him, and you're like, well shit, how did this happen? And then there's a seventh hero with laser beam powers, and he fights the asshole 1v1 in a sports match. But the asshole doesn't take the win and decides to kill everyone instead, so the two fuse into one person in a pool of silver shit (which gave the main heroes superpowers earlier) and lift a giant door that kills them, and then it turns out the island they were on was trapping them from returning to a city underground.
Well, turns out EVERYTHING is underground, including hundreds of (much smaller) island and two continents. And the wise leaders were actually heroes when they were younger but before that they were normal citizens in this city, and they gave up their power to save everyone. By the point they were driven up, the city was destroyed, and there was a massive genocide across the entire underground universe by magic spiders that mutate people. And that one asshole? He's just the leader of an organization of other assholes that's responsible for doing this. During the 1000 year span between events, his organization has been at war with the biggest criminal syndicate in the universe, because the asshole and that groups leader got in a fight over a mask with time powers that the guy who turns invisible made when he was still a hero, except that guy escaped with the mask because of a MAD threat and got a couple years of "please don't attack us" out of it.
Flashback to the present, the current heroes get BTFO by skull faces, after going to ANOTHER island on the surface that got shot up, to find a mask with life powers because god is dying. And then some new guys have to go take care of that, but they also have lightning powers, and were originally villagers from the original set. And then it turns out that that island was shot out of the chest of god, who is actually a giant robot. And the one island they were on? It was a disguise for his face. And these robots they fought before? They were just trying to clear it so they could wake him up. Oh, and apparently this great earthquake that killed lots of people (there was an earthquake, not just spiders) was because the robot crashed into a planet, which just happens to be one of the three fragments of the original planet it was built on by wizard-scientists so they could rebuild their planet after a giant war fought over that same stuff that gives people super powers.
It also turns out the asshole knew all of this because one of his friends talked to Bionicle Cthulu and learned the secrets of the universe, and his whole plan was to possess the giant robot body and become god. And then he succeeds at the last minute, even though his minions almost fuck it up, and it turns out the whole last three years of story is just a fuck you to the good guys for falling for it. So god gets stuck in the life mask and goes to the desert planet, where the locals teach him about shit and he helps them stop an invasion of muslims by killing Bionicle Giganigga with a backstab. Then they unearth a prototype robot and the asshole shows up with the original body, and the planet gets combined, but the asshole gets brained and the body collapses to the planet, and now everyone lives happily every after.
Except for all of the plot threads that never got concluded when the story ended, like who actually survived the massive holocaust when the asshole took over the universe, or what sort of government would develop, or the small fact that one of the wizard scientists stowed away on the robot and was the only reason anything in it developed personality and consciousness instead of being robot slaves, and a bunch of other crap.
By the end of the series there were about twenty elemental powers, a couple hundred characters, a few dozen locations, and more stuff unwritten than not.
