What'd I want?
I'd imagine this story to span across three years. Starting off with a series.
Episode One - the Dream
Premise of this episode would be based around showing us how much Spherus Magna has changed, everyone living a giant peaceful metropolis - Schools and Libraries replaced the battlefields and Taverns with Inns replaced the arenas. However, as the episode progresses, we get to learn that the utopia is not as real as it seems - the Dark Hunters are secretly still there. At the end of the episode we get introduced to a "chief" of the city's police. To our very surprises, he is a Skakdi Dark Hunter - posing as a simple enforcer of law. He gains the Toa's trust except for one.
Episode Two - Shadow's Rising
Here we learn that the Dark Hunters are much bigger influence than the original idea of the first episode, showing masses of noble and political figures being aligned with the Dark Hunters. The Toa will be greeted and invited to one of the noble's house to consult their ideas. As the episode progresses, we will uncover the Dark Hunter, setting the Toa on a journey to find their elemental masters, the ones to teach and let them come to the realization that the city they lived in was not as clean as they had it for.
Episode Three - Hard Road Ahead
This episode will focus around developing the Toa's character as they seek out Turaga of the old times to teach them their true arts. I'd Imagine the Fire Toa to be Hot-headed, the Fire Turaga to be calm and harsh on his student. The Water Toa to be Strong yet rational, often outspoken, The Water Turaga to be calm and relaxed, perhaps a bit to much for her pupil's liking. The Earth Toa to be wise yet quick to get ahead of himself while the Turaga would be a bit reckless, crazy but wise at the same time. The Air Toa would be a free spirit and essentially Lewa, sharing his personality with the Turaga, they'd understand each-other well. The Stone Toa would be a fan of sports, he'd be determined and steady, The Turaga would be very opposite. He'd prefer peace and quiet - both of them would share the element of patience. The Ice Toa would be a team spirit and natural leader, often a bit too pushy on his friends while meaning well while the Turaga would be quiet and observant. At the end of the episodes, the Toa will be told a prophecy of their journey by the Turaga, they'd set them off to find their own paths.
Episode Four - The Prophecy
This one would also focus purely on character development, showing how each Toa deals with the prophecy - The episode would end up with cliffhanger as all the Toa are captured at the same time, thrown into the same cell - It'd be made out of a mysterious element that they couldn't heat, control or destroy.
Episode Five - Escape from Prison of Illusions
The Toa would eventually find their way out of the prison cell, only to find out that they are in a maze, clearly, they weren't meant to get away. Each of the Toa would decide to go a different path and along the way, strange vision would show up to them, teasing them about their pasts or tempting their needs - further developing the Toa - in the end, all the Toa would make it out alive, only to find out that this secret maze was located beneath the City's real, open prison.
Episode Six - The Festival of the Toa
An episode that'd be centered around the Toa and a festival that marked the day the Makuta fell - embracing the Toa and the Glatorian. The Toa would be honorary guests on the festival together with their Turaga. For a while, they'd enjoy the party until the lights went out - then everything changed. The Toa had to fight in complete darkness a foe they couldn't see - at all. Suddenly, the episode would cut to follow three hooded figures - One is a female with very sharp voice, the other is deformed and small male, the third being a very tall and sleek male. These three figures would approach the Chief of the Police who was already established as a secret Dark Hunter. The figures would reveal themselves as Makuta. The Tall one rarely speaks and appears to be very slim. The female Makuta bosses the other two around, her attitude is mocking and ragefilled. The third Makuta is absolutely nuts and crazy - but he can run like a devil. Te three proposed an alliance with the Dark Hunter upon which he rejected and laughed them off. Soon, this was changed when the female makuta would force him into submission, giving him no other choice than to agree. Then the shot cuts back to the Toa, turning the lights on, only to find the hooded attackers running away.
Episode Seven - The Legend of the Makuta
Here the Toa were introduced to the past we already witnessed, told about who the Makuta were - giving us flashbacks of each of the Makuta we knew so long ago, respectively going from Makuta Icarax to Makuta Teridax. Eventually, the toa will learn of the Makuta's fate - with one of them bringing up the question: Are they really gone?
Episode Eight - Warden Trouble
The Toa would be called to a routine mission, in order to defend the city's prison from a breakout. They'd fight all the prisoners back, eventually clearing the prison. In their joy, they'd enter the Chief's chamber only to find him conversing with the tall makuta, well, only the chief was speaking - The Makuta would teleport away but the chief was cornered. The Toa saw enough to judge him. They'd manage to fight him and subdue him, the chief would rise one final question before he was taken away. That question being "Who do you think will keep this city safe now?". After that, he'd be dragged away with one of the Toa silently whispering "We will."
Episode Nine - Makuta Teridax
This episode time-skipped a few weeks ahead, showing how the Dark Hunters became more prominent, they would face countless attacks in a montage of the past few weeks. The Toa eventually decide to find the root of the problem, so they went undercover and joined a small Dark Hunter task force. They'd eventually be led to a sewer which turned out to be a giant base of the Dark Hunters, sadly, not being their whole force. - They'd witness the Three Makuta step above the podium, claiming a speech about the New World Order and stuff - eventually, the female Makuta would uncover a sheet. It was the time-old relic of Teridax's own body. She'd take out a vial filled with Antidermis - Teridax's Antidermis. Slowly, she brought him back to life. She then - proceeded to stand aside and bow to Teridax, declaring him the new leader of the Dark Hunters. The Toa would want to get out of there at that point but the Makuta noticed them and chased the Six through the tunnels, eventually leading up to the Toa running away.
Episode Ten - Makuta Teridax (part 2)
This Episode will revolve around the Toa going through the stress of their upcoming battle with Teridax, they knew they'd have to face him eventually - so they studied his feats and past, learning about Turaga Takanuva. When they asked in the library about what happened to Takanuva, they were told that it is unknown - he simply disappeared one day, obviously foreshadowing the future. The Toa would consult their Turaga about this and cook up a plan to lead a small Task Force down the Dark Hunter base again, this time, hitting the Makuta surprised.
Episode Eleven - Makuta Teridax (part 3)
The climax of this season, the Toa would descend down the base with their small Task Force, slowly sneaking pass all the Dark Hunters, eventually nearly getting caught by the Quiet, tall Makuta. In the end - they would find Teridax sitting alone in a war tent. To their surprise, the Makuta didn't even bother to turn around and look at them - instead, he was insanely glaring into an old book, slowly murmuring something about "Him.... The Great Spirit..." in shock, clearly Teridax has a great PTSD - eventually, the Toa are caught by the other three Makuta, captured and set to be executed and made an example of before the whole city. The Makuta managed to intercept all screens in the city, to watch the execution. In their darkest moment, the Toa would suddenly gain courage, break free and fight the Makuta back - instead of fleeing to their bunker, they fled into an unknown sewer. When the Toa returned to the Dark Hunter enclave, nobody, nothing was there - they all disappeared. - They'd all happily celebrate expect the Ice Toa who was looking off into the sunset - knowing this wont be the last they've heard about the Makuta.
Since this post is already too long, I will add the other three seasons later on.

Anyways, this is what I would do if I was given unlimited budget and set to make another generation of Bionicle - of course, my delusional dreams are just that... dreams.
