A/N: I had this one shot idea with my friends while I was at my own athletics day carnival, so this might become a story of have a few more chapters, it might not. My three OC's are the main characters in this story but one of the is more the main character then the other two. One's a mini assasin, another has an iron suit and the last one has magic. Just letting you also know that I may bad at writing fighting scenes. Hope you like it. I'll give you a description of what they look like at the end.

"We have the athletics carnival today." Jessy groaned.

They just had an intense training session with Natasha yesterday, very tiring. Well, not for Jessy since Natasha is Jessy's mentor.

"I still don't see the point of even going to school when Tony could hire a teacher to teach us." Mya grumbled. They live in Avenger Tower with all the avengers 'cause they are practically family.

"It's so we can keep our cover more hidden and I want to learn in a normal school enviroment." Milli replied, walking onto the athletics ground.

"Of course she wants to learn. Tony Stark's her mentor." Mya mumbled.

"Oh lay off her Mya, besides be quiet about that now we're in public." Jess scolded.

"Looks like Mya woke up on the wrong side of the bed." Milli sung teasingly.

"Oh shut up Milli!"

As they were walking to their house colour purple the girls overheard guys talking about which avenger was better. Including them.

"It has to be Thor I tell you! Or at least his sidekick Sparks, she's hot."

"No dude if your talking about hotness then it would be Black Widow or her sidekick Shadow."

"Your both wrong! It's Iron Man's sidekick Iron Girl."

"But none of you have seen what they look like behind their masks."

The girls got to far away to her the rest of the conversation but bristled at the word sidekick. They loathed that word because even though they had mentors their mentors were also family as well.

The day continued on while Mya and the girls laughed and had fun with their friends. Luna was in her puff sleeping bag suit and Emily with her raccoon onesie.

But that all came to a stop when the Earth started shaking. A black space vortex opened in the middle of the oval and a purple man with gold armour walked out of the vortex. The crowd of students chatter died down to frantic terrified whispers and hushed tones among friends while the girls were staring at the mysterious purple man. They then just looked at each other before asking questions.

"Is that who I think it is?"

"It can't be, can it?" Both girls looked to Mya since Thor is her mentor and Thor has mentioned him before.

"Yea, it's him." Mya swallowed not looking away from the mysterious man.

"But why is he here then? Wouldn't he be after the gu- I mean, the avengers?" Milli asked, correcting her mistake.

"Does he know about us?" Jessy added a little worried.

"I don't know. But from what Thor has told me about him, it could be anything." Mya shuddered at the thought of all the things Thor said to her about him.

They were silent for a few moments before Mya decided to lighten the tension between them.

"Although I kind of expected him to be taller and have a at least a few more scars."

Since the crowd of students were silent waiting for the mysterious man to do something so you could hear Milli and Jessy to surpress their sniggers.

"I am Thanos! I will soon I will rule this world or better yet, the whole universe! I shall mould it into my own image with you bowing at my feet." Thanos announced, his deep voice sending waves of fear into everyone. A mumble of murmurs ran through the crowds while the girls shared looks.

"Silence! But that's not what I'm hear for. I first need to wipe all the people who will try and defeat me. So will the young avengers come out of this crowd?" Thanos asked, no one stood up.

"No? Well that won't do. Fine, if you don't come out I will kill half of the people here."

"Milli get ready to call your suit when I say. Jessy, have you got your suit and weapons under your clothes?" Mya whispered.

"Always." She whispers back.

"OK then, let's stand up before Thanos actually kills them." Mya joked.

"Young Avengers." Mya said, looking at the girls.

"Forever." With that the girls stood up and headed down to the space in front of the students and teachers. Mya in front with Milli and Jessy behind her. When they passed everyone the heard whispers of...

"They can't be the young avengers it just can't."

"They're the weird ones."

"I always knew there was something off about those girls."

Yeah, they were not that popular at their school.

"Ah, here they are. Sparks, Shadow and Iron Girl. To be honest, I expected more."

"Thanos you want us then here we are." Jessy said.

"But we will only come with you if you let these civilians go." Milli added gesturing to the students and teachers.

"That seems reasonable. I will them go only when you come to me." Thanos said.

"Quick question though, why do you want us?" Mya asked curiosity gets the better of her.

"Simple, to use you as bait before I kill you and the avengers in one go. How do you earthlings say it, two birds one stone."

Mya turned to Milli and Jessy.

"When I say, Milli call your suit and Jessy hit him with everything you got. But only when I say." Mya muttered.

The two just nodded discreetly. So Mya just turned back to Thanos.

"Fine we accept." Mya called to him.

Just as Thanos took a step forward the avengers appeared in front of him blocking his access from the girls. Thor, Tony and Natasha held out a protective arm out to the girls whom looked relieved where Mya looked a bit put out.

"Please tell me this guy is just over enthusiastic for your colour." Tony said.

"Yea, he really is. We were just gonna invite him to have a cup of tea with us too." Milli sarcastically retorted.

"You do know I have a plan right?" Mya mumbled.

"I do not doubt you have a plan. But if it is to give yourselves up then it is a ridiculous plan." Thor replied. "You know how dangerous Thanos is, I have told you Mya."

"I know."

"Thanos you may fight us, but no harm shall come to these girls. These girls are not in the fight." Cap declared, said girls blushed and protested.

"Oh they are since I am to stop all people who will be in my way. So I can just kill you know." Thanos said launching into the air throwing the first punch.

It just got chaotic from there. All the students were screaming and running around while the teachers were trying to the students out of the oval. The avengers just went in to attack Thanos.

"You three help the students get to safety. I shall aid the team to defeat Thanos." Thor said to the girls while swinging his hammer ready to fly off and help the avengers.

"But we wanna to help you guys." Jessy protested while Mya and Milli nodded their heads.

"No, help the these people first then help us." Thor gave them the look that told them not to argue anymore.

"Fine." With that Thor went off to join the fight while the girls went to help the students and teachers.

Avengers P.O.V

Tony was firing pulse blasts at Thanos while Clint was shooting arrows at him. Though neither were affecting him. He advanced on Clint to attack him but never got there since Natasha gave him a kick from behind.

"Fools you think you can defeat me." Thanos laughed.

"No but we can damn well try." Cap replied throwing his shield at Thanos only to have it thrown back. While grabbing Natasha and throwing her to a wall affectivly knocking her unconscious.

"Nat!"

"I was expecting a challenge, clearly I will not get one." Thanos laughed.

"Well how about I try." Thor said flying to Thanos hitting him with his hammer. Then flying off to Clint, Tony and Cap who had regrouped.

"Ah you finally joined the party." Tony said.

"More like the party that's getting our ass kicked." Clint deadpanned.

"OK, let's knock him off his feet. Clint hit him with exploding arrows, Stark fire pulse blasts at him and Thor hit with the biggest lightning bolt you can get." Cap ordered. They all nodded.

"Avengers, Go!"

They all attacked just as Cap instructed but it did nothing. Not even a scratch. Even Thor's lightning bolt. Nothing.

"Pathetic. Now it's my turn." Thanos said jumping up and smashing down in front of them knocking Clint, Tony and Cap unconscious then jumping up again and grabbed Thor's ankle throwing him like a rag doll to the group of hero's out cold.

Thanos chuckled, "Who will save you know." Looming over them.

Girls P.O.V

"Move people, this way." Jessy beckoned.

"Hurry so you don't get hurt." Milli said.

Mya just spared a glance at the avengers to see how they were going. But what startled and shocked her was to see all the avengers knocked out unconscious on the track with Thanos looming over them. She guestured to the girls over to her.

"What's wrong?" Milli asked.

"I'm gonna go help the guys." Mya looked dead in the eyes of the girls. Jessy and Milli shared a glance.

"We'll help."

"No. I need you to get all the students out, then help me." Mya said.

"OK. Young Avengers." The two girls said.

"Forever." Mya finished.

They first pumped then Milli and Jessy went back to helping the students out of the track.

"Well Thanos. You wanted the Young Avengers, you'll get one third of them. ekam em elbisivni." Mya disappeared from sight and went to help the avengers.

Thanos chuckled, "Who will save you now." Looking over them.

In response he got explosions on his back knocking him a few feet forward. Thanos looked around and so no one there so he put two and two together real quickly.

"Oh come on out Sparks. I know your there."

'No point in hiding now' Mya thought.

"laever em." An echo voice rang through the air and Mya stood a few feet away from him. "Eit mih pu."

Chains wrapped around Thanos making him unmovable. Thanos just smirked.

"Ah Sparks. You interest me. Tell me how a mortal girl has magic powers? You are known in all the nine realms and universes thanks to Thor, prince of Asgard."

"I'm so flattered you're curious about me, I haven't givin' you a thought at all." Mya mocked.

"You dare mock me!" Thanos shouted, he tugged at his chains and they broke going everywhere. Mya had to shield herself from not getting hurt while trying to stop the chain parts from hurting anyone.

"Ezeerf sniahc." The chains just stopped in the air, completely frozen. "Well I did not expect that." She muttered.

"I won't hurt you, Sparks. No, your time will come soon though. But that doesn't say anything with your friends. All of your ends are near!" Thanos smiled evilly at Milli and Jessy who had their backs turned to help people. Pointing one of his hands at them and a red circle bolt shot out of it heading to the two unsuspecting girls.

It all happened in slow motion.

Mya ran as fast as her legs could carry her to shield her friends and she was there in an instant. The bolt split into three different ones. One for each girl.

"Dleihs su."

But the bolts went right through the conjured blue shield but something happened to the bolts though. They had electricity circling it when they hit their target.

Mya felt herself falling to the ground soon to be unconscious, the last thing she heard in the land of the living was Thor's war cry.

Then all went black.

Mya sat up with a gasp. She was in the infirmary by the looks of it.

"What happened?" She asked looking around to see all the avengers hear minus Bruce(he is in India). Thor was next to her bed, Natasha next to Jessy and Tony next to Milli. Clint and Cap were hovering around all the beds.

"I awakened as soon you three were hit by those red things. Then the others woke near after me." Thor answered. Mya just nodded.

"And Thanos?"

"Gone as soon as we woke up." Cap answered this time. Mya just nodded again.

"OK, and how long was I out for?" Mya said dragging out the OK.

"9 hours. It's 9:00pm now." Clint said.

"9 hours!" The lights in the room flickered when Mya said that. She didn't notice.

"How are Jessy and Milli?"

"Stable. They are alright though. No damage done." Tony said. Mya released the breathe she was holding.

Mya took off the blanket that was on her and swung her legs off her bed.

"What are you doing?" Clint asked looking warily at her.

"Umm. Getting off this bed." Mya answered back getting ready to hop off this bed.

"You are injured, Mya. You should be resting." Thor said sternly.

"I think-." What ever Mya was going to say was cut off by groans from Jessy and Milli.

"Ow my head." Milli said putting a hand to her head while sitting up.

"What happend?" Jessy groaned, looking around.

"Yo-." Tony got cut off by Mya.

"We got knocked out for 9 hours by those bolt thing that Thanos shot out of his hand. Thanos left as soon as they woke up. Our covers blown and you guys are in a stable condition. Long story short." Mya said quickly using her fingers to count off the stuff that happened.

"WHAT!"

"So yeah." Mya said. She was getting ready to get off the bed. Again.

"Mya what are you doing?" Cap asked.

"Going to my room and getting a snack to eat." She responded.

"Mya as I said before, you are injured you should rest." Thor said.

"I think I've had 9 hours of rest but fine." Mya submitted. "But I didn't say I would rest here. I'll rest in my room once i get a snack." With that she stood up from the bed.

After a few steps with everyone watching her, Mya swayed a little. Thor was by her side just before she fell.

"See I'm fine." Mya said while leaning her head into Thor's side. "Why is the room spinning?"

"Mya you are not fine you are injured." Thor looked at her sternly.

"Mya you need rest, all of you do." Steve said while giving a look to say 'don't argue' to Jessy and Milli.

"I will rest when I'm in my room." Mya said in a small voice muffled by Thor's side.

"Then I shall escort you to your room Mya." Thor said looking at Mya like she was his daughter.

"Right then let's go." Mya's head came out and the two went to Mya's room.

As soon as they left Natasha said the real obvious.

"That girl is stubborn to a fault."

"We know." Everyone present in the room said. Tony and Natasha looked at their student/family member.

"You two don't even think about moving from that bed." They said in unison. Milli and Jessy looked at each other before saying.

"Not even gonna try."

"Good. Now get some rest, you have school tomorrow." Steve said.

"Have fun at school." Clint sniggered on his way out.

As everyone left the infirmary they could hear, "Not funny Clint!" from both girls.

Mya and Thor P.O.V

When Mya and Thor walked into Mya's room, Mya was drained from the walk from the infirmary to her room.

"I think I'll skip my snack and go to sleep instead." Mya yawned.

"Yes, I think it best Mya." Thor chuckled. Putting her into her bed. Thor was on his way out of Mya's room when he heard his named called.

"Hey Thor."

"Yes, Mya."

"What should Jessy, Milli and I do about school tomorrow?" She asked.

"I do not know." Thor said puzzled. "Just act like you normally do so."

"'K." Mya nodded, "Night Thor."

"Good night." Thor whispered closing her door.

Mya rolled over in her bed closing her eyes in the process. Her last thought before giving into sleep were Thanos' looming words.

"Your time will come soon, Sparks. The end is near!"

So what do you think? I came up with this idea while I was at my own athletics day carnival with my friends. The characters are a little OOC cause I can't get them spot on. Bruce will not be in this story cause Bruce is my least favourite character and I can't WAIT for Avengers: Infinity War to come out in cinemas. Mya has long dark brown hair, Milli has short dirty blonde hair and Jessy has Frizzy chestnut brown hair.

Plz PM or review about any ideas you have or what you think about the first chapter. I own nothing other then the plot and my OCs.
