The god and the Assassin(Bucky Barnes x oc) rewrite

Chapter 1

Bucky's pov

I sat in Tony's compound, staring blankly at the table.
"Anyone seen Thor lately?" Tony asked, searching around.
"Should we have seen him?" Steve asked, leaning forward on the chair he sat in.
"Well we've not seen him in a while. It is strange" Bruce mumbled, stretching the bottom of his shirt. As if in response, the door to the room burst open, Thor walking in with his arms outstretched.
"Hello there fellow avengers. How are all of you doing this fine day?" he boomed, walking forward.
"Speak of the devil" Tony muttered. With him were two much slimmer people, a girl and a guy. Compared to Thor, neither were as well built as he was. They looked similar to a burglar with their slim stature. The Girl looked very similar to the guy, the only difference really being part of her hair, some of her clothing and her gender.
"Brother. Do you have to be so loud?" the male asked, with a grumble and a sigh. He looked at the girl who's gaze was wandering around the room, a look of wonder and excitement on her face.
"You brought Loki?" Tony asked, raising an eyebrow.
"Now now. My brother is a reformed man. He won't do the same thing twice" Thor explained, putting an arm over Loki's shoulders. The Girl looked at me and her face practically lit up. She ran over, picking up my metal arm and running her fingers over it.
"Cool. You have an arm that looks different from the other. How is that? Is it magic? Are you a hybrid? Please tell me. Please. I wanna know" she begged, eyes fixed on my arm.
"Eir. We talked about this" Loki sighed, placing a hand on his face.
"But dad. It's so cool" Eir protested, leaning on her tiptoes.
"Dad?" Steve asked.
"We'll yeah. Have I been doing it wrong this whole time. Am I supposed to call you mum?" she asked, looking at Loki. Thor burst out laughing.
"Loki. As a mum. I wish that I could see that" Thor laughed, practically keeling over from laughter. Eir blinked in confusion.
"Alright Thor. Who is this?" Tony asked.
"That's my neice, Eir" Thor introduced. Eir let go of my arm and zipped over to Tony and began shaking his hand.
"Nice to meet you. I'm Eir Lokisdotter or Lokisson. Whichever works. Oh and I'm the god of peace. What's your name?" she asked, still aggressively shaking his hand.
"Tony Stark" Tony replied. Eir let go of Tony's hand and zipped back over to stand next to Loki, hands going up to fidget with the peace sign trinket that hung from the collar around her neck. Loki reached into his pocket and handed Eir something. She gently took it and began munching on what I think is a bar of chocolate.
"Since when did you have a neice?" Tony asked.
"Since Eir was born" He shrugged.
"And you didn't think to mention this? Ever?" He asked again.
"It was never important to the conversation" Thor shrugged.
"I mean. This is Eir's second time on Earth and she was barely even here the first time" Loki stated, shrugging his shoulders.
"You can see the resemblance. They look quite similar" I explained, refering to Loki and Eir.
"I like them" Eir stated happily, bouncing up and down on her feet.
"I think it's safe to refer to that one as a male" Loki whispered but I heard him. I blinked but didn't look much into it.
