This story has been written like months ago and I just started really liking it and decided, why not just go with it? So, here is MIGRAINE.

Also, Face Claim for OC's are Astrid Berges Frisbey for Danielle (I know I face claimed this actress for Rori from my story Fix You, but I decided to use Charlotte Le Bon for Rori instead) and Nick Robinson for Jack.

Enjoy.

They were children when it happened.

Jack had just turned sixteen, and his little sister, Danielle, was turning 10 in the Fall. Two innocent children with dreams and hopes of the future living in a small village in Slovakia when their father was kidnapped and mother murdered. The two children pleaded and begged for the armored army men not to take them, but they did anyways. They ripped them out of their school yards and shoved them into large vehicles with hoods over their heads, blinding them. Neither knew what was going on or what to do. All they could so was cry for their parents.

The men spoke in fluent German and tossed the children around as if they were animals. Both siboings assumed they were German soldiers, maybe rescuing them from danger. But it was clear when they finally took the hoods off and began to handcuff the kids to large metal chairs in a sterile cement room, that they were not, in fact, rewcui them in any way shape or form. What they were doing, however, was preparing for something they referred to as the 'Transformation'.

The children, clueless, had no idea tha their father was a scientist who worked for the group in charge of the abduction. Henrik Harper, an astounding and acclaimed scientist apart of HYDRA, who refused to perform tests using alien weaponry on anyone. So, as punishment, HYDRA killed his wife and kidnapped his children with the soul purpose of them being the first two test subjects to be experimented on using the Scepter the Norse God had dropped in New York during his attempt at taking over the world.

"No! Please!" Dr. Harper cried as the HYDRA soldiers locked both children in separate cement cells and bound them tightly onto lab tables. "They're my children! I promise! I will continue the work on other people, but not them. Please." He begged Wolfgang Von Strucker who stood tall and solute in front of the glass that separated their room from the siblings'. While Dr. Harper was in tears, Strucker seemed to look... pleased.

Strucker merely shook his head. "I'm sorry, Dr. Harper, but consequences must go into play." He explained as a soldier approached the two children with the Scepter. "HYDRA does not tolerate weaknesses." He seethed before turning toward the armored guardian the other side of the glass, prompting him to continue the experiment. the soldier complied, walking towards the eldest child, Jack, as his father cried out.

"NO!" Dr. Harper began to run at the glass, but soldiers held him back and made him watch as Jack cried out in pain the moment the tip of the Scepter touched his chest. A blue light ignited from the gem inside the glowing chamber, moving a fluid motion into the boy's body. It reacted immediately, his chest rising ad yellow light began to ignite around every inch of the boy's skin. It was working.

But after only a few moments of the pain, the soldier picked up the Scepter and let the boy heave in pain. Little did anyone know, he had changed a lot after those few moments.

After Jack's experimentation, Danielle was next. Dr. Harper cried and sobbed as he watched the soldier with the Scepter make his way over int the next cell over. Danielle was crying now, pleading with him as she shook her head. "N-n-no, please," she whimpered through her sobs. "Please. Don't-" But her cries were silenced when the Scepter touched her chest. For Danielle, something reacted differently within her. It wasn't like Jack's.

On the other side of the glass, Strucker and her father watched as a large ball of light erupted from the Scepter involuntarily and sunk its way into took Danielle's heat. The little girl shrieked as the power surged within her body and through her veins. She gripped the seat tightly and stiffened in the chai, kicking and writhing trying to break free. Se screamed and screamed and screamed as a bright yellow light began to glow from not only her skin, but her eyes, her nose, her ears. She was going to explode, she was got go to die!

She didn't. Instead, the soldier retracted the Scepter and let the girl pass out from all the pain she had endured.

"What did you do to my children?" Dr. Harper asked in a defeated and broken voice as he watched in the opposite side of the glass. His bid was shaking and the tears were still falling. And all he could do was ask himself what he had done.

Strucker, smiling with a gleam in his eye, turned to the doctor and smiled. "I've just changed the world, Doctor." Suddenly, Strucker pulled a gun from his hi holster and aimed it at the Doctor's head, watching in satisfaction as his rival in HYDRA for years fell lifelessly to the ground after he emptied a bullet through his skull. He changed the world... He changed the world with Jack and Danielle Harper.

Dr. List approached Strucker as he did his evaluation on the two children in the cells. It had only been a few weeks since their initial experimentations. Since then, the siblings had begun to show enhanced abilities due to their exposure to the Scepter and it's powers. And Strucker couldn't be anymore pleased as he watched the Harper Siblings in contentment in their cells.

Jack seemed to be emitting yellow lightning from his hands and feet as he paced around his cell. Every once and a while he would shout scream and throw a fit, short wiring every light and electric device in the building. While he was impressive, Strucker was in love with little Danielle.

Strucker moved from Jack's side to Danielle's and smiled. Danielle sat curled up in the corner with her knees pulled over her face. She wasn't even aware of it, but every piece of furniture in the small cell was floating a foot off the ground around her. And that wasn't all she could do. Since the beginning, Strucker had noticed the girl's interactions with the Scepter were much more... reactive than her brother's. It was like she was the ideal lab rat for the experimentation. She had blossomed after the transformation and Strucker knee that this was by far the best creation HYDRA would ever come up with. Surpassing any of the Silver, Ghost, and Winter Soldier projects. The Enhanced Project was the future of HYDRA, of the World.

"Sir?" Dr. List got Strucker's attention as he handed him two Manila folders.

Strucker took them and began flipping through them. "Any successful experiments for me today, Dr. List?" He asked.

"Yes, sir. Wanda and Pietro Maximoff." The doctor stated as he pointed out the two file names on each.

Strucker raised an eyebrow. "Siblings?"

"Twins." List confirmed.

Strucker smiled. His plan for creating a superhuman program after HYDRA's failure with Project Insight and the Winter Soldier was coming along nicely. He handed List back the files. "Bring them to the base in Sokovia."

"And the Harper siblings?"

"Bring them as well."

Three Years Later

The Maximoff twins and Harper siblings became close over the years of being trained and experimented on in Sokovia. When they first met, Jack and Danielle found it hard to believe anyone would volunteer for the horrendous experiments like Wanda and Pietro did, but when the twins explained their bloody and brutal past in a war torn country where their parents were killed in a bombing, the siblings understood why.

Despite being brought in for different reasons however, all the children seemed to come together as a friend group of sorts. The three eldest, Wanda, Pietro, and Jack, all looked after little Danielle who was practically mute after first receiving her powers. Danielle talked to virtually no one and spoke very little to people she did which were usually just the three others. Wanda found it easier to communicate with Danielle through her telepathy while Pietro used a type of sigh language. Jack just used verbal communication with his sister, she seemed most comfortable with talking to him more than anyone.

Throughout their struggles, they had power and potential in them. Wanda had her telepathy and telekinesis through her scarlet plasma, Pietro had his super speed and white hair, Jack had control and manipulative abilities on electricity, and Danielle...well she had advanced telekinesis. Far more powerful than Wanda's. Unlike the 'Scarlet Witch', Danielle's power was all in her mind. She didn't use plasma and didn't even really need to make a motion with her hands to move objects. With a lot of tests, the scientists in charge of looking over her, found that Danielle could not only dissolve matter, but extinguish it. A revolution was what the scientist called her. 'Eris' was what Strucker and the other HYDRA soldiers named her.

The superhumans seemed to notice soldiers in HYDRA seemed to do that. Name them like circus freaks. They called Wanda 'Scarlet Witch', Pietro was 'Quicksilver', Danielle was 'Eris', even Jack was named 'Statix'. It was like they were their own branch of superheroes like the Avengers, although these two groups were different by far. It was until one day they collided.

It was chaos. Danielle awoke to soldiers throughout the Sokovian base rushing to prepare for battle as red alerts blared on the comm system above, they were under attack. Strucker was in the control room trying to regain control of the situation while the four enhanced were standing off in the hallway nearby on call if needed.

Jack turned to the other three while the HYDRA agents were turned away. "This is the chance we need." He told them. "We can finally escape, be free."

Wanda frowned. "They will only find us again."

Jack shook his head nd grinned widely. "Not this time. The Avengers are here. They can defeat Strucker and his men."

Pietro and Wanda gave Jack incredulous and hurt looks. "You're really trusting our freedom and safety in the hands of Stark?" Pietro asked.

"Not just Stark, Pietro. The team." Jack explained.

"No. Nuh-uh." Pietro shook his head. "If we're getting out of here, it's on our terms. We're on no one's side. Only our own."

Jack huffed. "Fine."

Pietro turned to his sister. "Are you with us?" Wanda nodded as Pietro turned to little thirteen year old Danielle. "Eris?" Danielle looked up at her brother before turning to the twins and nodded in determination. She didn't want to be here anymore.

The four enhanced came up with a plan to escape and began to go through. Pietro and Jack would head out into the woods while Wanda and Danielle stayed in the hidden room until the pair returned.

Jack and Pietro dashed out into the snow covered forest where the Avengers were fighting off Strucker's army. Pietro and Jack then split up. Pietro took on the straggler known as Hawkeye while Jack came between a gruop of HYDRA soldiers an Captain America. Jack glared at the Avenger before surprising him and sending a jolt of yellow electricity through the small group of soldiers. Jack turned to the surprised Avenger. "My sister," He explained. "She's trapped inside. Help me rescue her, please."

Captain America pursed his lips together. "We gotta take down that force field first."

Jack nodded. "They keep the main power source underneath the building."

Captain America's hand flew to his ear. "Stark, you catch that?"

Jack couldn't hear much but a muffled response, "Drawbridge is down people!"

Thor suddenly landed beside them. "The second enhanced?" He asked the Captain as he eyed Jack suspiciously.

"He's a blur." He replied. Jack frowned. Pietro.

"And this one?" Thor gestured to Jack.

"A friendly." The Captain explained. "All the new players we've faced, I've never seen this. In fact, I still haven't."

Something on the comms caught their attention. After listening in, Thor glared at Jack for some reason. "I can get Barton to the jet." Thor told the Captain. Jack frowned even more. Pietro hadn't listened to the plan and engaged Hawkeye. Damnit, Jack cursed to himself. "The sooner we're gone, the better. You and Stark secure the scepter."

"Copy that." Captain said before the trio's attention was turned to a group of soldiers charging from past the trees.

Thor tilted his head. "Looks like they're lining up." He commented as he twirled his hammer in his hand.

Steve shrugged and held his shield up. "Well, they're excited." He exclaimed before Thor skid his hammer across the shield sending a blast at the soldiers and tank knocking them all away.

"Find the scepter." Thor told the Captain before flying away.

"And for gash sake, watch your language." A voice on the comms scolded playfully.

Captain America chuckled and bowed his head. "That's not going away any time soon." He then looked back up at Jack. "Now, where's your sister?"

After some time spent in the hidden room of the base, Pietro met up with Wanda and Danielle. While Dani wandered around looking at all the alien tech in the room, Pietro angrily told Wanda what happened.

"You attacked the Avenger?" She demanded angrily at her twin. "I thought you said no sides!"

"I said we're on our own side. It means Strucker and the Avengers are our enemies." He told her. "That man leading them is the killer who murdered our parents. Ruined our lives."

Wanda bowed her head. "So what do you suggest we do?"

"We make them pay. Take them down ourselves."

"How? It's just us four against the 'Earth's Mightiest Heroes'."

Pietro frowned. "It's actually just us three now. Jack betrayed us and ran with the Avengers. He's not coming back."

Wanda stared dumbfounded at her brother before her eyes wandered to the small brunette who was out of earshot. "We can't do it with just us three." She told her twin.

"We can if we unleash Eris-"

"Pietro!" Wanda cut him off. "How can you think such a thing?! Danielle is our sister, not our weapon!" Pietro bowed his head in guilt. "Besides, we don't know what will happen if we can't control her when she gets that way? Especially if we don't have Jack with us."

Pietro sighed. "So what do we do?"

Wanda thought it over for a moment before her eyes wandered to the scepter sitting in a sealed container. "We create something greater than us." She said simply before turning back to her brother. "Go distract make sure Stark comes down here."

"But-"

"Just do it."

Pietro reluctantly nodded. "And what about you and Dani?"

"We're going to distract the Avengers." She said.

A few moments later, Pietro went off to steal away Jack from Captain America while he spoke with Strucker. Wanda and Danielle then approached. "How many are there?" The Captain asked Strucker just as Wanda sent a red plasma blast at him, knocking him down some stairs. Her and Danielle then retreated back through the door, Danielle slamming the door shut behind them using her mind.

"What now?" Danielle spoke up.

Wanda smiled a bit. "Back to the hidden room." They found themselves watching as Tony Stark made his way downstairs to the hidden room. He eyed the scepter, that's when Wanda knew what to do. She crept up from behind and used her telepathy to show him a vision, his fear. Wanda then came back to the shadows beside Danielle. The brunette teen looked up at Wanda questioningly. "Just wait, Dani."

Pietro came up behind them then as Stark came to from his vision and stared up at the scepter with determination. Wanda smiled. "We're just going to let them take it?" Her twin asked.

Wanda simply smiled with pleasure as Tony used his Iron Man hand to snatch up the scepter. "Yes..." She breathed.
