Summary: Loki and Thor have loved each other for along time and had twin daughters from that love. The daughter's names were Thorn Lokison and Lokia Thorson. Loki and Thor loved both daughters very much but only days after their birth they was stolen away by some unknown source. After that, Loki became spiteful and their marriage became a broken one...

Fifteen years after was when Thor had meet the Avengers and Loki had tried to take over the world. The Avengers had thought it was because Loki was power hungry but that thought was thrown out the window when Thor had over heard them discussing it and had corrected them.

Loki had wanted to take over the world because Loki found out, days after their daughters disappeared, that some sort of powerful human had found their way into Asgard and had stolen their daughters. After hearing this information, Tony took it upon himself to find his friends lost daughters. What will happen when Tony does find them? crossover with harry potter!

It was a normal day at the Avenger's tower and everyone was lazing around. It had been almost a year since the Avengers had defeated Loki and all the Avengers had bonded so greatly that they considered each other family.

Tony and Bruce had been sitting on one of the couches, the other couches and chairs had been occupied by the other, and were discussing their theories as to why Loki tried to take over the world while everyone listened in and commented when they thought it to be appropriate.

"-I mean why else would someone try to take over the world? The only logical reason is that he was power hungry and wanted daddies approval.", Tony stated as if it was the most obvious thing in the world.

"Tony, as I have told you before, there has to be some other explanation. Nobody tries to take over the world without some kind of logical reason behind it, I mean why would someone try to take over the world because they want to appease their father.", Bruce point out.

"Well-"

"Bruce is correct, my brother did not try to take over Midgard because he wanted power, he did it for other reasons.", Thor said, talking oddly quiet that they almost did not hear him.

"Oh, then why did he?", Tony asked stubbornly.

Thor tensed and took a deep breath before replying," Because he wanted revenge on the human race for kidnapping Thorn and Lokia."

"Thorn and Lokia?", Steve asked quiet and unsure after seeing his friend look pained from just saying the names.

"Thorn Odin Sif Lokison and Lokia Frigga Fandral Thorson were their names...they were me and Loki's twin daughters."

"Wait, you and Loki did the dirty? But I thought you two are brothers?"

"Loki is my adopted brother and we did not just make love. We fell in love centuries ago and wed, then Loki became pregnant about fifteen years ago. Everyone celebrated after finding out, and were even more excited when they learn that two heirs were to be born, not just one. I can still remember the day I first laid eyes upon them, Lokia had bright blonde hair and shining blue eyes, when she first laid eyes upon me smile beautifully. And Thorn, who was the eldest of the two, and had dark black hair and glowing green eyes. She just stared at me as if she was trying to tell if I was a threat or not and after it seemed as if she deem me worth, she shyly smiled back at me. Everything was perfect!", Thor smiled but then it faded and you could feel anger roll off him.

"Until one night, only days after their birth, they were stolen from their room. No one had known, not until we heard Loki scream from the children's room. When I heard him, I rushed in to find Loki sobbing in front of their overturned cradle. Father had sent everyone to search for our daughters but not even Heimdall knew where they were. Loki and I stayed up for days searching until evidence was finally found, evidence that a human had broke into Asgard and kidnapped our daughters. We still search even after find out that information but it was to no use, eventually everyone quiet searching and mourned for them. But Loki did not give up and took to despising humans and became hateful, our marriage soon fell apart after that. We are still married but our love has shattered because a human had stolen our daughters!", Thor was shaking with rage and look as if he was almost in tears.

All the avengers looked at him with sympathy and no one spoke for several minutes.

Tony had broken the silence with four simple words, " I'll find your daughters."

Thor looked at him, "That is impossible."

"Not for me, all I have to do is use my technology to find them, it should be easy if they are on earth. I promise you I will find them, even though I'm not a big fan of their mother.", Tony gave him a sincere look and smiled, he would find them even if he had to travel the whole world by foot to find them.

Thor smiled back," Thank you, man of iron, you have given me new hope in having my family back together again.
