I hope you guys like this first chapter, let me know if it's a fic you'd want to keep reading. I'm not sure when I'll be posting the next chapter, but I think one chapter a week is a good schedule. Also I'd love to know how you feel about the title.


Ylva Heindryn was many things, but a trainer was not one of them. Even if she had Steve and Nat beside her, she didn't know the first thing about training people. To her, fighting came naturally and so did her powers. So training two enhanced siblings with barely any actual fighting skills was going to be quite the challenge. Using powers was one thing, but hand-to-hand combat was a whole other situation. Standing in front of her were those same siblings, silently listening to Steve as he addressed them on what they would be working on and improving in their training.

"Alright, now that you know what you'll be doing, I'll assign you either Natasha, Ylva or me to train with you. Wanda you'll be training with Natasha and I, and as for you Pietro, you'll be with Ylva. Are you two okay with who I assigned?" he asked the twins.

"Yeah, I think I'll work well with a beauty like Ylva," Pietro said winking.

Wanda gave him a slap on the shoulder, telling him to shut up. Ylva chuckled, smiling at Wanda, who returned it. She wished she was assigned to Wanda, she knew they'd become great friends.

"Now that we're all settled let's begin" said Steve, walking out to the field behind the new Avengers base.

"So what are we going to do? You going to teach me how to run? I think I already have that down, or maybe we can just have a little fun," Pietro said smirking.

"Are you kidding me? No we are not going to play around, you need combat skills if you're going to go on any missions where fighting is involved. Which is every mission, so you need to get serious because people's lives depend on you okay?" Ylva exclaimed, already getting irritated with his joking manner.

"Okay, okay I get it, be serious I got it. But I have a question, why were you assigned to me? I doubt anyone can keep up with me, but if you don't have abilities why would you be paired with "an enhanced"?" he asked.

Ylva sighed, "you know nothing about me do you? I'm not a regular SHIELD agent, I'm from Asgard and I do have abilities" she said, crimson flames coiling up her arm.

"Whoa! What the hell, don't just whip fire out without telling me! I could have caught on fire!" Pietro exclaimed, jumping back.

She chuckled, "you won't catch on fire, I can completely control my flames. They don't burn anyone unless I want them to" Ylva said, extinguishing the flames.

"I have other powers too, I can show you or are you too scared?" she smirked.

"I wasn't scared, just surprised" he said.

"Alright then, what's your favorite animal?" she asked.

"Favorite animal? Uh I guess a dog, why?" Pietro asked.

"You'll see" she said. Suddenly Ylva's body glowed with a bright light, Pietro had to look away from the brightness and when he looked back he was stunned. Where Ylva stood was a fluffy Golden Retriever looking up at him.

"Where'd she go?" he said looking around.

"I'm right here you ninny, can't you tell it's me? I'm the dog" Pietro heard her voice in his head.

"Wait, you can shape shift and talk telepathically?" he exclaimed.

"Yes I can shape shift, I'm a shape shifter. And no I can't communicate telepathically, it's only when I'm in animal form" she said, turning back into her human form.

"That's amazing! You're amazing! How'd you get such cool powers?" he asked excitedly.

She blushed, "thank you, but actually I don't know, I've always been able to conjure fire and change shape since I can remember. I guess I was just born with my abilities" Ylva said.

"I heard you got yours from Hydra right? How fast can you run? Do you have a speed limit?" she asked.

"I don't really know if I have a limit, I mean I just run, I never know how fast I'm going" Pietro said.

"Well then there we go, let's start with figuring out how fast you normally go and after that we can find your limit. Assuming you have one. Let me grab my phone, I have a speedometer on it so we can see exactly how fast you're going" Ylva said.

"Wait, if you're from Asgard how do you know how to use a phone? They don't have any in Asgard right?" he asked.

"Well when I was recruited by Fury he made sure I knew everything there was to know about this world's technology, because I would be staying here for quite some time" she said.

"Don't go anywhere alright? I'm just gonna get my phone and then we can start" she said, running off into the building.

A few minutes later Ylva came running back with her phone and bagels.

"What are the bagels for?" Pietro asked.

"Well when I was getting my phone Wanda told me that you need to eat a lot because you have an extremely fast metabolism, so yeah, bagels" she said, handing him two.

"Want some cream cheese with that? Or are you one of those plain guys?"

"Nah, cream cheese is great" he said, quickly spreading on the cheese and shoving it in his mouth.

"Geez, don't you have any manners?" she asked, cringing.

"What, you don't like my way of eating? Sorry princess, but I'm starving" he said.

"Ugh don't call me that, I hate being called that. It's bad enough to have everyone in Asgard bowing to me and calling me princess, but here it's just embarassing" Ylva said, sighing.

"Wait, your an actual princess?! How are you a princess?" Pietro asked.

"Yeah I'm a princess, my brothers are Thor and Loki, the princes of Asgard! How do you not know this? Has no one told you anything?" she exclaimed.

"Well the other Avengers told me about themselves, but not much about you. All they said was that you were from Asgard and that you'd be part of the team training me" he said.

"Oh well that makes sense, I'm kind of new to the team so they probably didn't know what to say. But that's alright, when we're done training you'll be able to mow down a whole hoard of Hydra agents in the blink of an eye" Ylva said smiling.

"Huh yeah, I hope so. I think I'm full so can we start now?" Pietro asked.

"Sure. Okay, ready, set, run!"
