The sight of stars was always breathtaking. They were an endless sea of jewels sparkling in a bleak void. Just as one would disappear and die, another would be born to take its place. Such was as the order of the cosmos, and to him, it was fascinating.

He had studied many of them, from simple suns to binary stars to nebulae and much, much more. With them, he had seen the worlds circling around them, and the life each held. To him, a giant of perhaps seemingly impossible height, they were like giant balls of swirling colors on top.

This world was the same. Much larger than himself, and termed with life everywhere. The machinery inside of him scanned the many sapient beings in the planet. He could only wonder what sort of cultures and peoples he would see.

However, that thought stopped short. Something stirred inside him. Something, but what was-

Before he knew it, everything started to shut down. His head, his entire body reacted against his commands. His limbs jittered in small spasms before they went limp with the rest of him. As his vision faded in and out, dark and malevolent laughter filled every corner of his mind. He barely had enough space to recognize the one responsible.

'Brother…'

It came too late. His body was unresponsive to his thoughts, and even his mind was fading away. All he could do was only plummet into the gravity well of the planet below…

Atop the high peak of the tallest mountain among the Four Nations stood Avatar Zulong. The long ends of his red robes, showing his origin in the Fire Nation, and his long, gray beard billowed in the powerful winds. It bothered him little, and he focused his blue orbs on his reason for being there. The giant monster, its body too blocky to be human, floating high above the clouds, yet so visible for all across the world to see.

Zulong had seen it before the Fire Lord's messenger had reached him. Several days ago, he had been with the Air Nomads and Fire Sages, mediating their debates of Spirits and the Spirit World when the giant of a near-impossible size appeared. With such a presence in the sky, Zulong took it upon himself to get a good look and packed enough food for the journey. On top the mountain, he waited and watched the strange behemoth for days, perhaps to see what would happen.

Now, he saw it clearly falling. Not hard to notice when a fiery aura surrounded the body. Its large back fell first, the head limply faced upwards. What was worse was that the body grew bigger and bigger as it fell.

Zulong commented in his raspy voice, "A frightful sight. Wouldn't you agree, Talon?"

Beside the avatar, a low growl of concern answered his question. Zulong smiled at his longtime dragon friend and companion, and he gently rubbed the azure scaly snout. "Don't worry. It'll be alright, old friend," he assured and moved to the back.

When Zulong quickly sat atop the saddle, the dragon flapped its large wings and flew up. Talon's serpent-like body slithered through the air like a grass snake and drew closer to the target. The closer the dragon came, the more fierce the wind became. It was so strong that Talon roared against the fierce winds and would have knocked off the rider.

Zulong kept still and was surprised by the sheer size. Seeing the mountain for a human so close, Zulon would have thought it would have crushed a mountain, if not several, under its weight. 'I'll need more than I thought,' he realized.

His dragon roared once again, and Zulong held into the rocking body of his dragon. "Easy, Talon," he said soothingly. "I'll take it from here."

The avatar closed his eyes and tensed his body in preparation. The many days on the mountain were filled with communion with the past avatars and the Spirits of old. They all agreed what to do should the need arise. Zulong knew what he needed to do. He just hoped he had what it took to stop this megalithic monster.

Inhaling and exhaling, the old master of the four elements took his Airbending stance. He bent his knees and then, with a swoosh, he flew off his dragon. His trajectory aimed right at the falling mass of a near-impossible size.

Eyes still closed, Zulong spun his body around, his Airbending skills turning a human corkscrew. He went higher and higher and higher into the air until he hung aloft the wind currents. Immediately, he felt heat, as strong as lava, touching his face. In spite of such troubles, Zulong calmed himself and opened his eyes at last to reveal the glowing white light of the Avatar State.

Using the power of the past avatars, Zulong twirled his hands. The heated air responded by swirling around the colossus. As soon as it moved, however, there seemed to be no effect. Zulong kept trying, circling his arms to bend the hot air around him. Wisps of wind followed the motion and circled around the giant.

For what felt like hours, Zulong circled his arms in the same pattern. He could the hot air stinging his wrinkled skin as sweat poured on every portion of his body. He was used to training near the volcanoes, but this felt hotter than any lava river in his home region. By now, he could barely keep himself still in the air.

Zulong continued to bend the air the best his could. He could feel the hot air around the col swirled his arms around and continued to send blast after blast of air. Each one did nothing, or so it seemed. As Zulong's Airbending mentor, Rahshi, once said, "Alone a single wisp of wind can doing nothing against stone. But done again and again, it can bring down the greatest of mountains." So, Zulong continued in efforts.

That was until a gust of hot air pushed Zulong back, and he tumbled for a bit before setting himself back up. He bit back a curse as his body racked with searing pain. In spite of the power of the past avatars, Zulong's strength weakened, and he felt it. His mouth dried to a point he thought was impossible, and his ends of his robes quickly caught on fire from extreme heat.

Even with the Avatar state, Zulong strained with all his might, every ounce of his body and will, to change the very air around him. It felt like his body was about to break at any moment. He closed his eyes, reaching into the depths of his predecessors and those dwelling in the Spirit world. He only gave two words to them: 'Help me!'

Just as Zulong thought of it, his call was answered. The winds and clouds slowly shifted from their original course, and the Avatar began to feel a new power course through him. With his newfound strength, Zulong swirled his arms, adding to the momentum. He watched the falling giant with careful purpose. He had already thought about how to stop such a creature on the mountain. He did not need to stop this monster. Merely redirect it.

And in one last swing, redirected it Zulong did. The air currents responded to his movements. Clouds shifted towards the giant, changing the direction of its fall. Instead of hitting land, it dove into the ocean that was even too big for its size.

As the light of the Avatar State left his eyes, Zulong gave a tired glance. He left his body plummet down a mere few seconds before his dragon Talon swooped down to catch him on its back. Resting, Zulong watched the monolith of a creature slowly sink further and further into the depths of the ocean, too vast even for its own size.

Sighing in relief, Zulong let the strain take its toll. His body collapsed on his dragon, and already he could feel the darkness ready to swallow him up. Still, seeing the yellow fade away from the monster's eyes, Zulong could not help but feel pity. A new being had appeared before the world. It had not harmed anyone, and whatever caused it to fall was not of its own volition. A passing-byer, maybe, on its own journey. Whatever it had been, it merely sank into the great depth of the ocean.

'Perhaps… it would have made… for a good friend…' Zulong's tired brain thought as his last breath join the wind.

On that day, everyone all over the world, whether it was during day or night, had watched the entire event. All would watch as the "monster" submerge into the ocean. Hurricanes decimated the towers of the Air Nomads' temples and tossed the Water Tribe ship upside. Tsunamis turned the Earth Kingdom's mainland shores into swamps and flooding a few border islands of the Fire Nation. In the aftermath of such destruction, hysteria spread all across the Four Nations.

Many of the common folk and even the nobles believed it meant the end of the world, or it was the wrath of an angry Spirit seeking to right the wrongs of humanity. No one had an answer, and no one would receive one from Zulong or the new avatar born in the Air Nomads.

Their lords, kings, chiefs, and ruling councils would calm their subjects, yet even they held some fear for it. Any claims on the monster became empty as no one, not even the best swimmers in the Water Tribes, could swim deep enough to find it. Soon, after a century's passing, the entire thing would be nothing more than a dotted note in the history books or stories to frighten disobedient children.

Even then, it was not the end. The historians would say the powers of the Avatar had reached their peak on that day. Some would say it was what ultimately led to the four nations to secretly fear the avatar's power, which led to his or her reverence, as well as Fire Lord Sozin's genocide of the Air Nomads nine hundred years later. However, in the next thousand years, none of them would ever know the secrets inside the massive gargantuan that nearly destroyed the world.

Then, that all changed at the tail end of the Hundred-Year War, when two children of the Southern Water Tribe came across a magnificent discovery during their hunt...

AN: Another crossover (what a shock)-this one between Avatar: The Last Airbender and LEGO Bionicle. While Bionicle is more mechanical characters and Avatar has more fantasical elements, both have elemental powers and astounding mythos. Plus, both allow for each franchise to interact with one another.

There have been other crossovers including these two. However, there aren't many and most focus on each franchise being their own separate universe instead of merging the two, so I wrote this tid bit. I doubt that it will be an actual story, but it's nice to see what it could be and what it could become.

That's all for now.

Raika out.
