A/N: This is my first crossover story so let me know what you think
Disclaimer: I own neither Thor or Legend of Korra.
"If I were proud of the man my son had become even that I could not say, it would speak only from my heart...go my son" Odin smiled as Thor turned to leave.
"Thank you" were the only words that passed through his lips as small smile came to his face feeling true acceptance from his father for the first time in a very long time. He did not notice the once warm smile on Odin's face twist into a smirk a midst a shimmer of gold and green.
"No... Thank you" Loki laughed silently to himself as he waved his hand casting spelling that surrounded his brother without him being any the wiser. A punishment that would wound Thor in a way no axe or spear could.
"Oh what fun this will be" he whispered to himself almost unable to contain the mirth that he felt.
Something was wrong, the bifrost never acted in the manner. While the trip could be jarring to those unused to it this was something else entirely. Thor felt as though he was being tossed like a rag doll; it felt much like when Loki had dropped him from the helicarrier, but this was much more unsettling and painful as he bounced off the vibrant walls within the bridge faster than the speed of light.
Thor shouted for Heimdall hoping the stalwart gatekeeper would be able to aid him. But there was no answer and no help to be had, for the first time in a great while Thor felt helpless as he was subjected to the unstable path the rainbow bridge craved through time and space. As he tumbled through the cosmos his thought shifted to Midgard, his friends, and to Jane with a deep dread he wondered if he would ever lay eyes on his love again, and with the image of Jane in mind the god of thunder lost consciousness.
Like a great leviathan opening it's the maw, the unstable bifrost opened far above the ground and belched the unconscious god as though it were spitting some fowl taste from its mouth in a mass of flames, and with a force yet to be witnessed by the mortals of this realm. To those below it must have been a frightening sight as the sky opened up and produced an angry ball of fire. The great mass bellowed and churned as it plummeted towards the earth before it split into two distinctive forces that continued on their own paths. The larger of the two landed with a thunderous crash in the middle of an open field before a legion of soldiers and machines of war, the other landed far behind the approaching army. Both slammed in to the ground with the force of a small meteorite creating small craters and spewing dust and debris high into the sky.
The approach of the Earth Empires forces were halted as the sky ripped open and vomited a ball of flame. It seemed as though the Spirit world had launched an attack on them as the inferno split and landed on either side of their forces. The fear they felt was covered by their masks and mechs but the collective aura they the army gave off oozed fear and apprehension, that is accept for one at the front lines. Their leader stood disheveled from her fight but she held herself high and did not let the scene unfolding before her affect. While she was rattled her conviction was not shaken, she was determined to take the city before her and nothing would stop her.
What was once a hectic scene beforehand was shattered by the falling force, the whirlwind created by the air bender was smashed by the impact of the unknown object. The air a still with apprehension as both sides stared at crater between the two sides. The first to approach it was Kuvira much to the protest of her army, but she was not only to allow herself to appear intimidate or unsure in front her entire army. She was well aware that this was not the wisest approach but after nearly losing to the Avatar she had the reaffirm her will and strength. Intellectually she knew that none of those behind her questioned her ability, but she none the less felt the need to be the first to approach the unknown, to be the bravest, to be the strongest. Her features were set like they were carved from the earth she controlled, but for a moment her face shifted to shock. She had seen many things in her life but what she saw at the bottom of the crater left her confused, at the bottom of the impact lay a man seemingly unconscious but she could feel the thrum of his heart through the earth, steady and strong as though the fall had not harmed him. Her curiosity was piqued but before she could act a blast of air sent her rocketing backwards as she heard the roar of an air bison.
"Jinora what are you doing? We need to get Korra out of here!" Opal shouted to her as Jinora swiftly approached the mysterious crater.
"There is something down there, it's putting out an outlandish amount of spirt energy we can't let Kuvira get her hands on whatever it is, get Korra on Pepper and then get to the bottom of the crater I'll provide cover" Jinora shouted back to her friend as she slid down to the bottom of the crater and whipped up a whirlwind. When she saw what lay on the bottom she shocked to see the form of a large man with golden hair. She had never felt anything close to this amount of energy from anyone, Korra included.
The sound of approaching soldiers filled Jinora with trepidation, but she remain focused on the task at hand. In a short manner Pepper landed beside her with Opal, Korra, and her siblings in tow.
"Quick, help me get him on board" She commanded as the others jumped from the bison's back. They first attempted to carry him to Pepper's saddle only to find that he was considerably heavier than he appeared, it was like try to lift a boulder. In a panic the four air benders created a gust of wind beneath the unconscious man and hefted him on Pepper's back who groaned in response to the added weight. But the bison managed to take off with relative ease as they dodged the capture attempts made by the earth empire forces. After a few tense moments they were out of danger and on their way to Air Temple Island.
"What was so important about this guy we had to risks our necks and Korra's to get him?" Milo asked the tone would expect from a child who thought he knew everything. Jinora shot him a quick glare before responding.
"I'm not sure… something about this guy emits huge amount of spiritual energy. Normally I can't sense things this clearly unless I'm meditating" she spoke as her hand slowly hovered over the various chakra points. The others looked at her slightly confused, the way she described it almost seemed as if this man before them held more spiritual energy than some the spirit wilds.
"Korra, you can fell it right?" Jinora asked for confirmation from the Avatar hoping that she would be able to reaffirm her decision.
"Well… I can definitely sense something is not normal about him, but right now I can't sense much of anything right now" She responded the exhaustion evident in her eyes as she leaned back against the wall of the saddle.
"He doesn't seem so special… he sure is cute though" Ikki said with a smirk as her comment earned her questioning looks from the rest of the group.
"Look let's just get back to Air Temple Island, and then we can decided about the stranger we saved, right now what's important is that we get Korra back to Republic City" Opal offered to the group. There were nods of agreement from most of them, Milo glared at the unconscious passenger before agreeing in huff, which elicited small smiles from his sisters.
After a long day of flight the day finally started to give way to night and the events of the day caught up the Avatar and her companions. One by one they had drifted off the sleep both mentally and physically exhausted. Jinora gave a quick glance at her sibling and Opal to make sure they were all sound asleep before she made her way over to the barley conscious Korra.
"Hey, how are you feeling?" she asked the Avatar her voice laced with concern.
"I'm doing alright, just tired I guess" she answered still half asleep.
"Look Korra… I didn't really want to bring this up in front of others because I didn't want them to be concerned but happened to you out there, I thought you had gotten control over the Avatar State?" Jinora treaded carefully trying not to offend Korra.
"I… I thought I had, but something happened when I was fighting Kuvira, it wasn't like the other times, I don't know what it was" the defeat in her voice was almost painful to listen to, Jinora couldn't image what it felt like.
"I'm sorry I brought it up Korra, but I know you'll get through this you always manage" Jinora said placing a hand on her friend's shoulder, it seemed to help as it elicited a small albeit genuine smile.
"So what exactly is up with guy, what's so special about his spiritual energy?" Korra asked trying to change the subject.
"Well I'm not exactly sure what it is, but this guy's spiritual presence is…well it's unlike anything I have ever sensed before"
"What exactly makes it so unique?" Korra asked quirking an eyebrow, not quite understanding what she meant.
"It's not just it the sheer amount of power he's emitting, but it's an energy that I've never felt before, it's almost like Raava and Vaatu" she responded not quite sure how to describe it.
"So this guy is…what? Is he some kind of Avatar like me or my uncle?" the subtle shock on her face was apparent even in the dying light.
"No, not exactly, from what I can tell he is not two separate entities like you and Raava, his energy seems more…pure, more singular" her words were not certain or absolute, the way she spoke was more befuddling than enlightening.
"Sooooo…he's a spirit? He seems pretty human to me" Korra's confusion was only growing at this point.
"I don't know Korra, but he's definitely not something this world has not encountered before" Jinora said her face turning sober.
"Heimdall what is the meaning of this!" Odin bellowed as he entered the main chamber of the bifrost.
"I'm not sure my king, one moment he was there the next he disappeared from my sight" He responded his voice as even and calm as ever.
"I do not care how it happened just find my son" his voice was low and stern leaving no room for error, failure was not an option.
"Of course my king" Heimdall's voice did not waver, he would not fail his king. As the all father turned his once serious expression turned to one of glee. Things had worked better than Loki could have hoped for, he had only expected to strand Thor on some distance world removing him from Asgard long enough to finalize his plans, but the fact that Heimdall's gaze could not locate him meant he was far removed from the known realms. With a soft snicker Loki felt as though things were finally going his way.
