Alright, so this is a little chapter I decided to make that takes place during the Tidal Wave. During the event itself and afterwards in Shattered Destinies, I never really gave much detail into what Mata Nui was personally doing during that.

Well, I aim to rectify that right now. I did have a rough idea of what he was doing in advance, I just didn't want to spoil the reveal of his secret weapon in Shattered Destinies until it happened. But enough talk, let's dive right in, shall we?

Disclaimer: I do not own Bionicle, Halo or anything else that appears in this story.

From the moment Dark Samus had kidnapped Allana Solo, Mata Nui knew that things with the Flood were going to get really bad, really fast. The Republic Supreme Commander and Separatist Ruler knew that too, especially with the revelation that the Gravemind had taken control of the Throne of Balance.

From there on, things snowballed quickly; from the God Brother Relics of Remnant, the Spear of Destiny, and the Infinity Stones, it was clear that the Gravemind had started its endgame, with the two superpowers desperately playing catch up.

The Unitologists had been a distraction, and now it was too late to stop the Flood. The last thing Mata Nui had done was escort the inhabitants of Earth-199999 back home, before returning to Spherus Magna and preparing everyone for the worst.

The Gravemind's laughter was the signal that the worst had already arrived. All across the multiverse, Flood forms were teleported over worlds en masse, beginning their infectious rampage as the Gravemind continued speaking insults to everyone.

Republic space was no exception, and indeed, was hit far worse than anywhere else with the exception of Separatist territory. The Flood sent Star Roads to ravage the fleets and worlds of the two superpowers, no doubt remembering who had defeated it last time.

Of course, the Great Spirit knew it was time to break out the gift the Supreme Commander had given him, and as such, when the Flood began to rain down upon the Republic capital world, he was already prepared.

Now inhabiting his massive body once again, Mata Nui fought with everything he had to keep Spherus Magna safe. Energy blasts capable of shattering mountains lashed out. The energy of the Ignika flared, granting power to wipe out Flood forms in their tracks and even destroy Star Roads.

This body's capabilities far exceeded that of his old one, with the energy of the Mask of Life itself being amplified by this gigantic form. In addition, it was equipped with weapons and defenses that allowed Mata Nui to endure damage that would have previously destroyed him utterly.

In addition, while he didn't have an entire world inside his shell like the previous one, he still had more than enough compartments to hold millions of beings. And that's what the Great Spirit was doing as he fought the Flood, teleporting Agori, Matoran, civilians and any non combatants to safety inside his form.

And meanwhile, while he served as a formbidable force on both the Ground and Space, he was helped with the former by Toa, Glatorian, Order of Mata Nui members, and Republic forces, while the Republic fleets and defense stations provided all the aid they could from the latter.

And it wasn't enough. No matter what they all accomplished, no matter how many Flood pods and Star Roads the Great Spirit blasted out of the sky, there were always more, an unending tide of flesh and neural physics that hammered down on everything, twisting all life they could.

And as they made landfall, it was clear that not even the creations of the Great Beings were immune to being infected by the Flood. Through hyper advanced sensors, Mata Nui could percieve a number of Rahi and fauna being twisted into ravenous monsters, their organic components more than enough for the Flood to work with.

In fact, despite the best efforts of the warriors on the ground, the Flood were already breaching bases and structures across the planet, further causing untold devastation to everything around them.

Then the Flood came into contact with Energized Protodermis. The result was both less and somehow more disturbing than any prediction they had had. It did absolutely nothing. Energized Protodermis neither changed the Flood, nor did it destroy them.

In the end, it didn't matter. Mata Nui ended up in the crushing grip of several Star Roads, and although his defenses had kept them from crushing him outright, they were failing fast. Just as it looked like the end, however, scanners detected a massive energy wave propogating through reality.

The familiar energy annihilated every Flood form and Star Road it came into contact with, leaving the Great Spirit with no doubt that the two leaders of the Republic and Separatists were responsible.

Though judging from the rampant portals suddenly appearing and disappearing, as well as various other effects, it was clear that this wasn't nearly as clean as it had been during the Great Flood war.

"Is it over?" That was the voice of Kiina speaking, drawing Mata Nui's attention to those on the ground. There quite a few more than he had expected.

"Yes." The Great Spirit answered the Water Glatorian, his voice carrying across the entire planet. "I believe that this is finally over."

They had won, but not without cost. The damage the Flood had left in their rampage had been extensive, and as the reports from Admiral Thrawn had confirmed, the Republic and Separatist leaders had been lost, locking themselves in the Void to keep the Galactimind from ever returning again.

Even as Mata Nui spread the energy of the Ignika across Spherus Magna once more, healing what he could of the world, it was unlikely that the multiverse would ever fully recover from the loss of so many people.

But there were survivors, and for now, that was all that mattered.

Okay, and that's the end of this chapter. I'll admit, I kinda rushed through it just a bit, so I apologize for that. Still, this showed off a few details I wanted to clarify, like just what Mata Nui was doing, and also just what effect Energized Protodermis would have on the Flood.

Anyway, with all that said, I hope everyone enjoyed this chapter and reviews are always welcome.
