A.N. : This story is something I've been wanting to write for awhile. I've had the urge to write an Avengers story for the longest time. I was going to do just a one shot but it wasn't coming out the way I wanted it and I really didn't like it all that much either. I don't own anything Marvel. Just my OC. Her name is Kari and it means pure. Everything else you'll have to find out as the story progresses.

Chapter 1

I remember every day of my life like it plays on repeat in my head. Including my birth. Perhaps I've seen it in a past life but I can tell you one thing, I am living my life very differently than many other Midgardians. If you don't know what a Midgardian is then you need to catch up. Every so often some Midgardians are taken to Asgard. Some to become servants or to be maids but I was brought as a baby as a playmate. From the moment I was born and my mother died holding me in her arms after pulling me out of her womb herself to my first time seeing the rainbow bridge as a newborn. I've seen everything, including seeing two young princes of Asgard and looking up at the king of Asgard. Once Prince looked like a one year old maybe even a two year old and he had blond hair that I could notice. I couldn't see all that much since I was a baby. The other one was like me almost a newborn and he was in the queens arms but he had black hair. And I'm not sure if my vision was just off since I had been born probably only hours before or what but his skin was a light shade of blue and then it faded away. I was being carried by Heimdall as a child and handed to the king.

"Hello young one.." He said to me as I was staring up at him with my barely open eyes. I could almost see my reflection on his eye patch. Pale skin, small patch of brown hair on my head, my eyes almost black, small nose and full lips. I remember slightly tilting my head and whimpering for food. I was a newborn so it wasn't shocking. He had handed me over to a nurse who had exposed her breast and allowed me to suckle upon her breast. I had latched on and I remember seeing Odin look down at me from over the Nurse's shoulder.

"I already know you can understand me child…" He spoke to me and the weirdest thing is I could understand absolutely everything he said to me. "Every so often a child is born in Midgard...even at infancy they are known to become one of the smartest beings in the galaxy. Aristotle, Galileo, and you my child are no different. Even as you can see me now as your eyes are barely open, I can see the bright mind that will only continue to grow the longer you are." I opened my eyes a little more as I looked at the king and the nurse started patting my back in an attempt to burp me.

"You young one will grow beside the prince's...help teach them friendship and other traits that they will need to know as they mature…" After my burping the nurse handed me back to the king and he touched my head and closed his eye as he began to whisper some type of chant.

"Now dear what did you do to the little girl?" The queen came closer with the other baby and I had turned my head and looked at him and he looked at me as well. And for some reason when I looked at him I couldn't help but smile softly.

And then from then on out, The God of Mischief and well The God of Thunder as well were going to be my closet and only friends.

Eventually the King handed me back over to Heimdall.

"Heimdall you shall be her...protector…" the king stated and I looked up at Heimdall. He smiled softly down at me before nodding to the king and taking me away. I cooed up at him and he leaned down and kissed my forehead softly.

"My child...I promise no harm will come to you ever.." he whispered.

And from then on out, Heimdall was to protect me and raise me. Heimdall was my father.

It's been many years since that day. I guess you could now say I was about 6 years old although I'm not certain. The spell that Odin said to me as a child had turned me into a Demi god. I was still more or less a human but now I would live as long as Thor and Loki and the others. I didn't have powers though mind you. Unless you count being able to see unto earth like father. At first he fought me calling him that but now he's fine with it. Thor looked about 7 and Loki and I looked about 6. My days were usually always busy. Spending it with the princes of legend. Sometimes Loki would try to teach me the magic his mother was teaching him and sometimes Thor and I would spar for fun. Mostly I was there to be friends with both of them.

But a lot of my time was spent with the young God of Mischief. I liked Thor don't get me wrong but Loki and I got along so well.

"Kari keep up!" Loki looked back at me and I smiled and kept on running behind him keeping up with him. That little patch of brown hair that I had had grown out and was a deep brown now but I had a single streak of blond growing through my hair which was the effects of the enchantment Odin put on me to make me a demigod. I smiled at him and took his hand as I ran with him. I thought I almost saw a blush on his face and I giggled. "Come on we are gonna miss our chance." I whispered to him. I had played a few pranks with him before and came to find that I greatly enjoyed it. We ran to try and find Mama Frigga. To most she was the queen but I looked up to her as if she was my mother. So she allowed me to call her that. Loki and I were sneaking up behind her giggling softly but then she disappeared from in front of us.

That meant one of two things. Either that was a clone of hers to prank us or she caught us.

"When will you two ever learn." She chuckled softly and when we turned around Mama Frigga was right behind us.

Yep she caught us. Loki and I turned around and Mama Frigga was there and I giggled nervously while Loki just smiled.

"Hello mother.." Loki hugged her and I smiled at them. Loki loved his mother there was no question in that.

"father I found them!" I looked and I heard Thor and then saw him running over and he tackled Loki and Odin was walking close behind. I knew this was a family matter and I looked at Loki. "Come find me when you guys are done." I giggled softly and kissed Lokis cheek. I always did this to him cause it would make him blush and I couldn't help but giggle as I skipped away to find my father Heimdall. He was overlooking the earth of course and I hugged him tightly.

"Papa can I ask you something?" I looked up at him curiously.

"What is it my child?" He hummed and kept his gaze forward as he always did.

"When I was born...my real momma did she love me?" I held his hand and I saw his gaze drop down to me and he nodded to me.

"Kari...your mother loved you so much she allowed herself to perish so that you may survive and she prayed for us to come and save you with her last dying breath." He spoke to me and I nodded. He was always this straightforward like this and it made me happy that he never hid from me. I held his hand and was watching the earth with him with a smile. When I held his hand it was almost as if I had his sight as well and I was allowed to view the realms and the earth as he did. I smiled softly at how the Earth was changing and progressing.

I never would have known how much it was going to progress when I would later visit the planet of my birth once again.

Later that night I hadn't been able to see Loki till after dinner. And after everyone had gone to sleep already. I woke up to him shaking me awake as he always did. It was an illusion but if he used enough magic his allusion could touch me.

"Loki we are gonna get caught one day." I yawned and sat up. We aren't doing anything bad because we are children but we were supposed to be asleep right now.

"No we won't." He crawled into my bed and laid beside me and I sighed and laid my head back on the pillow.

"I...I don't think my father likes me." Loki quietly admitted to me and I looked at him shocked.

"Loki your daddy loves you." I looked at him confused and I sat up. He breathed in and shook his head. "Loki what makes you think that?"

"Earlier..he was telling me and Thor about Jotunheim...and that we were both born to be kings but...he really only looked at Thor when he said that." He admitted and I sighed. I didn't realize this then but this was only the beginning of how much I would come to realize that Loki would feel inadequate to Thor and how I would come to realize that no matter what I would be there for him. I held his hand and he looked up at me and I smiled.

"Loki you were born to be a king." I smiled softly at him and he blushed.

"Do you think so?" He looked at me a little shocked and maybe even a little nervous.

"Father mentioned that...also one day we would have to be married...Thor is probably going to marry Sif." He said to me and I shrugged.

"That sounds about right." I looked up at the ceiling in my room.

"He says...I would probably marry you.." he looked at me and I blinked a couple of times. I mean I guess it makes sense. I smiled softly at him.

"That's okay Loki. Then we can really be friends forever." I giggled softly and he looked shocked when I said that and he hugged me tightly.

We haven't talked about that night since then. But when I hugged him back and smiled softly I knew it was going to be one of my favorite memories of all time.
