A/N: I do not own Avengers or Agents of S.H.I.E.L.D.

The Only Thing I Have Left

Chapter 1:

"I told you...you'd die for that." Thor Odinson said darkly as he glared at the purple Mad Titan kneeling before him in pain. Stormbreaker inside his chest. After that declaration, The one eyed King of Asgard and God of Thunder grabbed the hammer portion of the Axe and thrust it deeper inside the Mad Titan, causing him to yell in pain again.

Thanos started speaking despite the agonizing pain he was in.

"You...You..should have..."

"What should I have done creature?" Thor asked with barely restrained hate.

The Mad Titan took a few more deep breaths before looking up at the Asgardian with a dark look on his face. "You should have aimed for the head."

He slowly lifted up the Infinity Gauntlet. Thor followed his movement before looking back at the purple being kneeling before him.

"What are you doing?" he questioned warily with a narrowed left eye.

Thanos grinned at him before getting his armored fingers in a certain position that the Thunderer knew all to well.

Thor's eye widened at that. "NO!" He exclaimed cocking his right hand back into a fist, with blue electricity surrounding it before launching it forward.

But it was too late...

Thanos the Mad Titan had already snapped his fingers together. The wound on his chest healing completely, before he disappeared to an unknown location somewhere in the Universe. Stormbreaker fell to the ground with a heavy metallic clang, leaving a small sizeable crater in it's wake just from the sheer weight of it.

Thor's electricity powered fist struck the spot where the Mad Titan had been just moment's before. The blue lightning left his fist and struck the entire forested area in front of him with an explosion, turning the once covered area into an open meadow and the ground charred black.

The Thunderer couldn't believe it. After watching his people be butchered and slaughtered at the hands of Thanos's children. After watching Heimdall get stabbed straight through the abdomen by Thanos himself and after seeing Thanos snap Loki's neck with the Infinity Gauntlet on, Thor's sanity was almost at it's limit. But the biggest insult Thor had found almost heretical was the fact that the Mad Titan had the audacity to use the Power Stone to blow the ship to smithereens desecrating the already deceased Asgardian corpses, jettisoning them further into space. That only served to further enrage the God King in his predicament.

Thor knew the severity of his error as soon as the lodged Stormbreaker fell free from Thanos's chest and the Titan disappeared to wherever the hell he went.

He gloated. Instead of taking a more lethal shot, Thor aimed for his chest just so he could have the satisfaction of telling Thanos that HE was the one who killed him. He wanted to see the light of life leave the bastard's eyes.

But now...the chances of that happening were a billion to one.

All because he let his pride and bloodlust get in the way of doing what needed to be done. Now because of his foolishness, half of the Universe's population are dying and turning into dust at this very moment.

Thor honestly wondered what in the hell he did to deserve all of this. In his 1500 years of existence the Universe never seems to give him a break. It was always just one thing after another. But this...this was just the last straw.

Which of course drove the already mad God into an even further rage.

Thor's left glowing blue eye started turning a glowing blood red. The blue electricity surrounding him started turning red as well, the crimson currents dancing around his form. He looked down at his left hand and saw his skin turning black and the color was traveling up his armor and onto his face. The Thunderer felt his hair turning white and started spiking up a bit.

The Berserker Rage or "Warrior's Madness" as it is called was starting to take effect. In all of Asgard's history, Ancient texts described the Berserker Rage as a state where one takes all of their grief and emotional ties that happened in their life and it becomes centered causing the user to incite a transformation and increase their strength and power times ten. Other ancient paragraphs describe the user as having black skin, glowing crimson eyes, and white spiked up hair. All sense of reason and morailty gone the moment the transformation is complete. Only the Warrior trained Gods can achieve this transformation, whereas the Sorcerers and Mages have different abilities and arcane energies an thus cannot. But the truth is...there are only a select few individuals in Asgardian history who have achieved this power and kept it a closely guarded secret that they never let others see in the light of day. Not even Odin Borson the Allfather of the Asgardians could achieve this power.

Thor Odinson just so happened to be one of those select few. It happened back in the 9th Century when some of his Viking Worshippers slaughtered an entire Christian Monastery in his name. Men. Women...and Children. Not one soul survived. As soon as word got out about this atrocity, Thor slaughtered every individual that was involved and cursed their progeny afterward. To say that he was shocked and ashamed would have been an understatement. After that was all said and done he stopped interacting with Earth for sometime.

Coming back from his musings, Thor decided to take a deep breath and calm down his mental state. It would do no good to cause destruction across the entire planet. With his skin, eye, and hair back to normal he let out a sigh of relief glad that he did not start destroying things on sight.

Sensing someone behind him, the Thunder God turned around to see a stumbling Captain America come forward bruised and out of breath. The triangular black shields on both his arms retracted from not being in use. Steve looked around for a bit before his eyes landed on Thor.

"Where did he go?" he asked the Thunder God

Thor knew the reason in the answer behind his question, but he did not have the courage to tell his longtime friend of why he had escaped. It was not neccesarily the WHY or the WHERE that concerned Thor, but it was the HOW, that he had to take into consideration of answering Steve Rogers. So he opted for the best used response.

"Thor where did he go?" Steve asked the Thunder God again.

"I am not sure Steve Rogers." replied the Asgardian as he slowly walked passed him holding out his right hand and Stormbreaker flew back into it. "He could be anywhere on a number of planets in the Universe right now and trying to locate him is out of the question at the moment as we do not have the means to do so."

Steve nodded in agreement before wincing and rubbing his left side where his ribcage is. "The first thing we should do is gather our wounded, regroup, and see how many of our people survived whatever it is that Thanos did." Seeing his friend Bucky turn into dust reminded him that there are people here on Earth and in the known Universe that were affected by Thanos. "After that we should probably send out a worldwide transmission across the entire planet and let the people know that we are here and try to restore order."

Thor nodded slightly not really paying attention as his thoughts were elsewhere. "Then it's best that you and the others get started on it then...I have somewhere else that I need to be for the time being."

Steve raised an eyebrow at that statement. "You just got back from, wherever it is that you were." he replied as he looked at Thor's new weapon that he was holding and then the metallic eyepatch that he was wearing. "Almost 3 years to be exact and just about anything can happen in that timeframe. Is everything alright?"

Thor had to give the mortal credit for that. Among the group of young midgardians (young to him anyway) that he had come to associate with since his banishment to Earth 7 years prior, Steve had been one of the very few people, besides Natasha, who is very perceptive of the actions of others, which could be very useful or very dangerous depending on the individual themselves.

But Thor hasn't been watching them closely all this time for nothing. So he responded accordingly. "For the moment I am content. Even though it bodes me ill to see that our foe has struck an underhanded tactic against us before fleeing into the stars like a fledgling fire demon. It is unwise to think of my own trials and tribulations when there is an entire universe out there with half of the general population's life force extinguished."

Captain America decided to take that as a yes. "Very well then. I'll leave you to your business."

Thor nodded. "When I return I will discuss what has transpired in the two years of my absence with the Avengers."

Steve Rogers nodded not saying anything about the Avengers disbanding and the rift between himself and Stark over the Sokovia Accords and the fact that the Winter Soldier practically murdered his parents. Even if it wasn't his fault. "Looking forward to that." He turned around and left the way he came.

Thor watched and made sure that Steve Rogers was out of sight before picking up his left palm and looking at it. On his palm there was a glowing red mark in the shape of a soundwave with words appearing under it: "The Shaking That Never Stops"

Thor raised his left eyebrow at that one in amusement. "So she is going under that designation hmm?" He laughed to himself. That was not the strangest coined description he had ever seen before. So be it. He has taken things in stride before so why stop now?

He flipped said palm around another glowing mark was etched on him. This time it was yellow and in the shape of a golden lasso and the words "Warrior Princess of Truth" etched themselves under the mark.

He grinned again as his left eye glowed bright blue. It has been over a thousand years since he has last seen her and she "left her mark on him" that caused his face to turn redder than the Reality Stone itself. "I hope she remembers the vow that I made to her all those years ago." He replied to himself as he allowed his thoughts to travel to the past and the union between the two of them. the strength she inhibited and the passion she can throw out caused him to shiver in anticipation and admiration of her. After all she is betrothed to him and he to her. He cannot wait to see her again.

Turning to look at his right hand the Asgardian lifted it up in his field of vision while he was still holding Stormbreaker. The third mark was a glowing combination of red, gold, and blue and it was in the shape of a four pointed star with four extra points in the openings and the words "Hybrid Who Soars In The Heavens" appeared just as quickly as the symbol did.

Thor looked on in curiosity at the third mark. This one was an unknown to him. He touched the symbol to try and get a feel for where she was at, but she was blocking his attempts to find her. The feeling she sent back through their bond was equivalent to the response of "Don't worry I'll find you soon when the time is right." So she wishes to remain hidden for the time being? Very well. He wanted her to come to him on her own terms and in her own time. He didn't push the issue but sent back a feeling of "I understand" as a response.

The Thunder God let out a sigh of breath as he realized he had been standing in the clearing where his encounter with Thanos took place for about two hours now. He really wasn't surprised considering all that has happened to him in the short amount of time.

He considered his options carefully. Three of his soulmates marks had just appeared to him out of the blue. One he knew personally, the other in only whispered conversations between Agents, and the third was very new to him completely. The Thunderer somehow had a feeling that this would not be the end of more soulmates being revealed in the near future. But little did he know that this was only just the beginning of everything. Goddesses, Cosmic Femmes, and many more would be flocking his way soon.

Not that it was a bad thing. Hell the newly crowned Asgardian King enjoys having relations with beautiful women every chance that he gets. It is practically all he did in his younger days when he was promoting his worship among the Norsemen, Scandinavians, and Germanic tribes after the many battles that they had fought with other lands across the different sea boards.

But that left him with a question that left him stumped.

Which soulmate should he go after first?

It was obvious that the third one didn't want to be found until the time was right. She is most likely hidden somewhere in the deep trenches of space. Even passed the Celestial Head of Knowhere and the Dwarven Forge of Nidavellir.

The second was most likely in another plane of reality fighting her own battles and dealing with her own problems...but at the same time she could also be here as well. It has been so long since he has last had contact with her that he misses her dearly. The bond he shares with her confirms the fact that she is alive and well...he just does not know where.

Which leaves him with the first. Last he heard she was working with...he shook his head. Nevermind that. There could probably be someone out there reading his thoughts right now and he didn't want to compromise her location.

He made his decision.

He decided that he would go after the first soulmate, logically as she was the closest one nearby. But before he goes to her, he has to make a stop in Norway to collect two items that was thought lost forever. An item that rightfully belongs to him and the other that was made for the Warrior Gods of Asgard.

Glad that he has a semblance of a plan in mind, Thor Odinson the King of Asgard, God of Thunder, and Lover To Many Women, took off into the air with a sonic boom. As he raced across the skies, he kept thinking to himself that maybe, just maybe...life would be a little easier on him despite the losses and indignities he and everyone else have suffered at the hands of Thanos and his children.

Looking at the things he had just gained not too long ago as well put an assured grin on the Asgardian's face.

Yes...perhaps things are starting to look a little brighter right now.

A clap of thunder was heard and he grinned wider.

He would be damned if he didn't make the most out of his life right now.

With a glowing blue eye and electricity surrounding his frame, Thor Odinson took off into the setting sun with a new purpose.

Find his soulmates and rid the Universe of the Mad Titan. Nobody was going to stand in his way. Come Hell or High Water.

One way or another, someone will fear the Thunder.

To Be Continued.

A/N: This has been in my head for some time now. I have been wanting to make a Marvel story for a while and this just popped up. Thor is my favorite Marvel Character and I have been thinking of ways to write a story with him so I decided to do an introduction near the end of Infinity War.

Second Note: I always pictured the Warrior's Madness as some kind of transformation along with the increased amount of strength that goes with it.

Third Note: I will be taking some things from the Prime 616 Universe and adding it to the 199999 Universe (basically the MCU). I will also be taking ladies from the DC Universe as well to add to the story as well. So if you have any character that you had in mind that you want me to add, drop it in a review or message me and we can talk Marvel and DC as much as you guys want.

I hope you guys enjoyed this and I'll see you next chapter.
