This is just the story of your character
You are Alexis Stark daughter of Tony Stark sister of the Maximoff twins. You may ask how your related to both the Maximoff twins and Tony Stark. Before your dad found Pepper he was the biggest playboy out there. He slept with all the girls he met and one of those was the Maximoff twins mother. You are the youngest and you were also experimented on by hydra. No one knew you were Tony Stark's kid until he did a DNA test on you to prove you weren't his child but turned out he was wrong. You have powers like Wanda but they are more of a dark blue colour. You were split up from your siblings when they joined the Avengers and you were still stuck with Hydra. You escaped one day and Roamed the streets until you found a place to stay on the side of the road. You fell asleep but were woken by a very kind looking old lady who took care of you. After 2 years of caring for you she was killed in an attack apparently the famous Tony Stark's robots was in control. You found the woman you liked to call Nana dead. You were emotional, scared, angry, upset and confused. You left the bakery you lived in with Nana and went out to fight the Robot who killed Nana. While fighting another woman started attacking you so you fought her back. She had reddish orange hair and wore a black jumpsuit. You kept fighting then you pulled her into a head lock and asked "what do you want from me" she replied "I want you to stop working with ultron" "who the hell is ultron?" You asked keeping her in a head lock "the robot that is killing everyone" she replied but before you could explain you weren't working for him you got hit very hard by a shield it looked like. You got up and started to attack the guy in the blue suit who threw the suit. After him and the lady in the black suit others came a guy with long blonde hair with lightning powers, some person in a red suit then a guy with a bow and arrow. Then your sister came while you were fighting the guys off with your powers and combat skills she was very proud of you and surprised by your skills but then all the people you were fighting started to gang up on you and you were doing well but started getting really bad cuts and bruises so with your sisters powers they all were suddenly swiped to the the left by a red magic mist. You recognised it immediately and called out your sisters name " Wanda?" "Oh my Alexis you're okay" she said while running and hugging you. All the other guys you were fighting before looked very confused then Pietro came and hugged you as well "Alexis we are so sorry" Wanda said while group hugging you " it's okay I have escaped and I'm back with my siblings" you replied hugging them tighter. "Wait Wanda and Pietro you know this girl?" The guy with the bow and arrow stood up and said. "Yeah Avengers this is our sister Alexis" Wanda introduced you " hi I'm captain America or Steve Rogers you look a lot like the twins and Tony mixed" Steve said " I agree and my name is Black widow or Nat" Nat said " are you sure she's not your kid Tony? And my names Hawkeye or Clint" Clint asked Tony. You wondered which one of the men was Tony none of the people looked like you. "Tony do you have a secret mini Tony? Wait I'm Thor but I'm always Thor I only have one name unlike these humans" Thor said then the person in the red suit took his helmet off that's when even you noticed this guy looked like you. "No she's not my child by the way I'm Tony Stark or you might know me as iron man" Tony introduced himself "I'm gonna need proof do a DNA test on her" Clint said "first we need to beat this army of robots" Nat says while hitting something that flung her way. The fight continued but when you thought it was near the end of the war even thought you thought that was all the time you suddenly felt a pain in your heart. You dropped to the ground screaming you didn't know why. Your blue powerful mist spread across the battle field hurting everyone touching the floor at that moment. Tony came to your assistant "what's the matter are you okay?" He sounded very worried "I don't know my heart just hurts arhhhhhh!" You started to scream again. Wanda came out when she heard your screams and explained why your screaming "Alexis calm down arrhhhh!" Wanda dropped beside you on the floor "Pietro just died we can feel it in our hearts" she said while crying you started to cry but kept fighting till the end. Once the war was over the Avengers took you to their tower and as Tony said he would he did a DNA test on you. "I'm telling you guys I'm not her dad see loo- oh my I'm her dad" tony said but you couldn't tell if he was excited or worried. "What did we say" Steve said "Well hello daughter" Tony said to you. "Hi dad" you replied "baby Tony is very cute" Thor said. That's the origin story for you character Alexis Stark.
