Soldiers And Spies

Chapter 15

After a few more days had passed by, the team were well rested and ready for their next mission. Clint and Natasha had been doing a lot of training with Steve, Sharon and Sam. Bucky had been helping Eva learn to control her powers in emotional and stressful situations. And Tony, with the help of Pepper, had been making adjustments and modifications to his suit, as well as the rest of the teams gear. Together with Jarvis, He had created a synthetic polymer that was extremely flexible, but had the strength of Kevlar. He used it to strengthen his team-mates uniforms so that they would hold up in a knife battle as well as hopefully stop a few bullets. Or at least lessen the damage.

As well as that Tony had come up with a recipe for an energy drink for Eva. It was full of electrolytes and various other things to help her recover quickly when he powers drained her. He also made up some in an injection form, in case she ever got too drained during a fight. The injections would help her instantly.

When the time came, Clint and Natasha flew the team to Washington in the quinjet, careful to stay under the radar as they were still being hunted by Thaddeus Ross. Fury and Hill had given them as much intel as they possibly could and the whole team had gone over it all extremely thoroughly. They knew the layout of the base, inside and out as well as some of the people they were likely to come across there. Along with Yelena, there were at least half a dozen other ex-Red Room agents still alive and working with HYDRA.

They landed the jet on the outskirts of Washington, a couple of miles from where the last remaining HYDRA base was located. From there they went on foot, not wanting to alert the enemy to their presence. The element of surprise was something they needed to maintain. When they neared the base, they saw the four guard towers that Fury had pointed out to them when he handed over the aerial shots of the base.

Clint, Bucky, Natasha and Steve each took their positions and lined up their shots with sniper rifles. On Steve's mark they all took their shots, eliminating the guards in the towers simultaneously with precision and silence. Once they were taken out, they had their window to get into the base. With their stealth training, Eva and Natasha made their way to the front entrance and each took out one of the guards at the door, before informing the team through their comms that they were clear to breach the base. They all entered through the same door and split off into teams of three. Natasha and Clint took the left corridor, while Bucky and Eva took the right one. Leaving Steve, Sharon, Tony and Sam to proceed down the main corridor, before they each split off into pairs further down.

Steve and Sharon cautiously looked around a large room that appeared to be used for storage. They found some small wooden crates, but they were empty. They came across a larger crate at the far end, big enough to have had a nuclear missile inside it, but that too was empty.

"None of the nuclear weapons are here." Sharon said grimly as she looked back at Steve just as two young women entered the door behind him.

"This doesn't have to be a fight." Steve tried to reason, but the women just glared at him.

Their response was to start firing at them.

"I'll take that as no then?!" Sharon called out sarcastically and blasted at one of them with a gun that Tony had made for her. It fired off shots much like the pulsors in his suit. When it blasted off the woman's arm, Sharon looked at her in slight horror, but the missing limb quickly grew back and she began to glow orange. "What the hell!?" Sharon questioned, looking puzzled and frightened.

Sharon shot at her again, blasting a small hole through the woman's chest, making her glow even brighter as it began to heal. Not taking the risk Sharon fired off yet another shot and the young woman cried out as her body fought to repair itself before she was engulfed in an amber light and her body exploded leaving no trace of her whatsoever.

Steve quickly covered himself and Sharon with his shield as part of the building collapsed causing the foundations to shake violently.

Clint and Natasha felt the whole building shake and they tried to get in contact with the others.

"Is everyone alright?" Clint asked concerned.

"Yeah we're fine. Something weird is going on here though. More HYDRA experiments I'm guessing." Steve replied gravely.

"You honestly thought we weren't prepared for your team, Natalia?" A voice taunted and they turned around to see a dark haired young woman standing there.

"Who the hell are you?" Clint asked while he stood in front of Natasha, shielding her as he drew an arrow and aimed it straight for the woman's head.

"Aww how cute. Is this your little boyfriend Natalia? Does he think he can protect you from me?" She laughed.

"I'll do my damned best bitch." Clint growled as he let go of the arrow and sent it soaring straight for her. The young girl lifted her hand up in the air and stopped the arrow in its tracks before flicking her hand off to the side and Natasha and Clint watched as the arrow fell to the ground with a clatter.

"She's enhanced." Natasha whispered to her partner.

"Great... now what?" Clint replied darkly.

"We kick her ass." She said as she rushed at the young woman, throwing a punch towards her face. But the girl was quick, she ducked the punch and threw one of her own back, connecting with Natasha's rib cage. Clint came rushing in, and using his bow he swung at her as hard as he could. She threw up her arm to shield her face and the bow connected with a clang.

"Seriously? More vibranium women? Clint groaned, before he drew another arrow from his quiver and slashed at her with it. She was too fast for him, and continued to block all of his attacks. Until she was blindsided by a kick in the head from Natasha, and Clint took the opportunity to plunge the arrow into the woman's stomach, avoiding anywhere he knew could have metal skeleton. As he tore the arrow back out of her body she began to bleed immensely.

"You bastard!" The girl yelled as she struck him hard across the face with her vibranium filled hand, sending him stumbling back. Holding her stomach wound she continued to try to fight Natasha off, but the Black Widow had her beat. Injured she was no match. As the young girl threw a punch at Natasha she countered her attack and grabbing her arm she twisted it around until she heard a sickening metallic crack. With a dislocated shoulder and a heavily bleeding stomach wound the young girl was pretty banged up, but still she wouldn't give in.

She kicked out, but Natasha grabbed her leg and stomped down as hard as she could on the girl's knee, dislocating her knee cap as well. The girl screamed out in pain and reached for her side arm. Before she could draw her gun, Clint fired off an arrow sending it right through the girl's eye socket and she dropped to the ground with a loud thud.

"That was intense." He said to his partner.

"Tell me about it." She smiled grimly. "Guys, we just took out an ex Red Room operative. She was enhanced with a vibranium skeleton. She was one tough little bitch." Natasha told the rest of her team through her comms.

"Copy that." Steve said warningly. "Proceed with caution."

"Thanks for the warning." Tony spoke through his comms as he and Sam searched their section of the building, when they heard Eva's voice come through the comms.

"We found some strange looking explosives but the rest of the rooms look empty, it looks like they were expecting us." Eva said grimly as they continued to search around.

Sam and Tony searched another room, where they came upon blueprints that looked like it was made for a train and two buildings, Sam shoved them into his backpack just as two enhanced Red Room operatives stalked towards them.

"Great." Tony said sarcastically as one of them tried to kick him but he blocked the attack and fired at her with his pulsors blasting her arm off but it quickly regrew as her body glowed orange.

What the hell...

It suddenly dawned on Tony that they had taken the Extremis serum that Maya Hansen had designed and created. He fired at her again, taking out one of her legs and she began to repair herself once more but it was too much. The Extremis overwhelmed her system and she began to glow bright orange. Tony shoved Sam behind a crate and covered them both as the young woman exploded, taking out the other girl as well as half of the room they were in.

"Tony, Sam, are you two alright?" Steve asked concerned as he heard the explosion over the comms followed by a lot of coughing.

"We're fine but how the hell did Hansen's serum get into HYDRA?" Tony asked stunned as they made their way out of the wreckage.

"I'm honestly afraid to ask." Sam replied quietly.

Bucky and Eva cautiously ventured around one of the rooms, when they saw Yelena step out then from the shadows.

"I'm amazed you two are still alive."

"Yelena." Eva growled as she looked her nemesis in the eye.

"I think it's time I finally finished the two of you off." Yelena laughed as her hands began to spark with a blue electric energy. She shot out her hands, directing a blast straight for Bucky and Eva threw up her shield in defence before blasting her with a hex bolt sending her staggering backwards.

Eva and Bucky moved quickly towards her, determined to gain the upper hand. Bucky came in with a flying punch to Yelena's face, a loud clang of metal on metal as his fist connected. He followed up with a few more punches before grabbing her in a choke hold. She flipped him over onto his back and attempted to stomp on his rib cage before Eva blasted her with another wave of purple energy sending him flying backwards into a wall. Eva rushed at her then, her knee colliding with Yelena's stomach as she doubled over, the wind knocked right out of her.

She recovered quickly, climbing back to her feet she threw a couple of punches at Eva, her vibranium fists connecting hard with Eva's face. Bucky came running in from the side, kicking Yelena away from his lover, and following up with another strong punch with his metal arm. But he was no match for the enhanced Yelena Belova. She grabbed him by the throat and lifting him into the air she began to surge her electrical powers through his body causing him to shake violently.

"Bucky!" Eva screamed as she released a huge blast of energy from her whole body straight for Yelena, knocking the Russian off her feet as she dropped Bucky, his body slumping to the ground. As much as Eva wanted to run to him, she knew that she had to act quickly. She blasted Yelena with another strong Hex bolt as she began to stand up, knocking her back once more.

"You will pay for all the bad things you have done!" Eva yelled as she blasted her once more. Rushing over to her, she grabbed her now weakened enemy, pulling her up from the ground by her hair. She proceeded to hold her in a headlock, cutting of her air supply as she wrapped her legs around her body, preventing her from being able to fight back.

"What is HYDRA planning!?" Eva growled. "Where are the nukes?"

"Silly girl... you can't stop it now." Yelena laughed.

"Stop what?"

"It's too late Evangeline, you and your friends... those of you that fight it... you will all die. The rest will be under the rule of HYDRA! The whole city... the whole country... the entire world. It will be magnificent!" Yelena told her.

"Too bad you won't be around to see it, bitch!" Eva growled as she twisted Yelena's head as hard as she could until she heard a metallic kind of snap and her enemy slumped to the ground.

Eva looked at Yelena's limp body on the ground as she took in the fact that she had avenged Malia and everyone who had been killed or tortured, this woman wasn't going to hurt anyone else. She ran over to Bucky and cradled his head in her lap, she placed her hands on either side of his head, 'James...James wake up...please.' Eva said telepathically and nothing happened for a minute, Eva felt tears stream down her face as she thought Bucky was gone. After a few moments Bucky coughed heavily and took a deep breath. Eva hugged him tightly, feeling deeply relieved that Yelena's shocks hadn't killed him.

"Are you alright?" Eva asked worriedly as she looked him over for any visible injuries, Bucky nodded and hugged her tightly.

"I'm fine Eva, I'm alright doll." Bucky reassured and held her tightly as he saw Yelena's dead body on the ground. They both stood up as Eva spoke to Steve through her comms.

"Steve we're clear here but it looks HYDRA took some stuff that they really didn't want us to find." She said grimly.

"Alright, meet us at the lab." Steve replied and the two of them left the room and found themselves facing off against two teenage girls in the corridor who were no older than nineteen years.

"You don't have to do this." Eva said quietly, trying to reason with them but they blasted at her.

Dodging their attack Eva kicked one of the women in the face while Bucky punched the other woman before shooting her, she staggered back in pain and that was when they saw the stab wound heal. Her face glowed then and Bucky cut off her hand, the woman screamed in pain as it started to grow back. Bucky grabbed her and threw her into a wall and she crumpled into a heap. He went to help Eva who was fighting with the other young woman. Grabbing her in a headlock Eva slit the woman's throat and she fell to the ground. She began to bleed out, but her whole body started to glow orange as her wound began to heal itself. The woman screamed out in pain as her body became engulfed in the orange light.

"Get back!" Bucky yelled as he pulled Eva into one of the rooms and behind a crate as the young woman exploded, causing the building to tremor.

"Steve! What the hell is with these girls exploding!?" Bucky asked as they rushed into a lab where the rest of the team had rendezvoused.

"I think it is the Extremis serum. HYDRA must have gotten their hands on it. It doesn't seem quite as volatile as when Aldrich Kilian was using it, maybe HYDRA have been tampering with it. But clearly it is still very unstable, more so than before." Tony spoke up.

"Great. Just what we need. HYDRA experimenting with more dangerous chemical cocktails." Natasha said bluntly.

"Well the upside is Yelena is out of the picture." Eva said quietly.

"For good?" Steve questioned.

"Well... I snapped the bitch's neck so... yeah. Safe to say we won't be seeing her again."

"Good riddance." Natasha sighed.

"We still haven't located any of the stolen Nukes. This is a real problem guys." Steve announced to the team.

"Yelena was saying something about HYDRA taking over the country and the world. Killing all who oppose them and ruling over the rest." Eva relayed the information.

"HYDRA is planning on taking over the world!?" Clint asked, alarmed.

"Sounds like it." Steve confirmed. "Problem is we have no idea what exactly they are planning on using the Nukes for. Did anyone find any intel?"

"Nothing." Natasha said, and the rest of the team nodded in agreement.

"I found some blue prints." Sam spoke up. "Could be helpful."

"Right, well two shield teams have just landed and are going to do a sweep of the facility before destroying it. I think we have had enough excitement for one day. Let's get out of here." Steve said tiredly.

They all nodded and started to leave, when Eva saw a memory stick on the floor under one of the desks.

"Where did you find that?" Bucky asked curiously and Eva pointed to the spot. They needed to find out what HYDRA was planning, and soon.

After everyone had showered and gotten back into ordinary clothes, they were now watching Tony place the memory stick into a computer. Immediately it seemed to hijack the computers system and the camera turned on focusing on all of them.

"Stark, Anthony Edward. Also known as Tony or Iron Man. Born May the 29th 1970." The computer said in an accented Russian voice as it focused in on Tony. The voice sounded so familiar to Eva, she would swear she had heard it somewhere before.

"Potts, Virginia Elizabeth. Also known as Pepper. Born August the 20th 1985." The voice said as the camera rested on Pepper then for a minute, causing the woman to look alarmed.

"Rodgers, Steven Grant. Also known as Steve or Captain America. Born November the 18th 1918." The voice said calmly as the camera focused on Steve before moving along to Sharon then.

"Carter, Sharon Catherine. Also known as Agent 13. Born September the 12th 1992." The voice said before the camera shifted its focus to Sam.

"Wilson, Samuel Thomas. Also known as Sam or Falcon. Born September the 23rd 1978." The voice said smoothly before the camera turned towards Clint.

"Barton, Clinton Francis. Also known as Clint or Hawkeye. Born January the 17th 1971." The voice said calmly before the camera focused on Natasha.

"Romanova, Natalia Alianovna. Also known as Natasha Romanoff or The Black Widow. Born November the 22nd 1984." The voice said continued as it shifted its focus again this time landing on Bucky.

"Barnes, James Buchannan. Also known as Bucky or The Winter Soldier. Born March the 10th 1917." The voice said before moving once more to focus on Eva.

"Nikolayev, Evangeline Marina. Also known as Eva or Psyche. Born June the 24th 1993." The voice said calmly as they all stared at the computer screen in shock.

"Must be some kind of recording." Sharon commented wearily and the voice chuckled in response.

"I am not a recording Miss Carter. I might not be the man my dear god daughters may remember me as." The voice said snidely as the camera zoomed in on Natasha and Eva then. "But I am still a man." He continued as a picture flashed up on the screen for a moment.

"You know this guy?" Tony asked surprised as Natasha and Eva's eyes narrowed then.

"His name's Pavlo Baykov, He's a Russian scientist. He was one of the people who created the Red Room serum. I didn't know he was my god father though..." Eva said darkly as she glared at the recording then.

"You can thank your fathers for the serum actually, it was their genius minds that created it. However once Yuri and Mikhail learned what we planned to do with the serum... they wanted out. They attempted to stop us but...accidents do happen." Pavlo said amused as two newspaper articles came up on the screen.

"Russia grieves loss of two world renowned scientists." Eva read aloud. "'Two brothers Mikhail and Yuri were killed in tragic accidents within three years of each other.'" She continued.

"Wait... are we...?" Natasha began as she looked over at Eva.

"Cousins my dear." The voice said finishing the sentence for her.

"That doesn't add up... I don't remember much about my parents, but I do know that I was orphaned very young. With mine and Eva's ages, if Yuri and Mikhail were our fathers then they couldn't possibly have died only three years apart. Eva didn't lose her family until she was eleven. He's lying." Natasha stated.

"You are very clever Miss Romanova... however your father did not die when you were quite so young." The voice told her.

"What... what are you talking about!? My mother and father died when I was only a little girl."

"Well, you are half right. Your mother was killed, but we captured your father. We couldn't just kill him, he was of use to us you see. It would be a shame to waste such a brilliant mind. He and Yuri had already been working for us. They tried to leave, so we had your mother killed and your father held prisoner. That was enough to keep Yuri in line… at least for a while." The voice laughed.

"We? Who is we?" Eva asked suspiciously.

"HYDRA of course young Nikolayev."

"Great! So now you're telling us that our fathers worked for HYDRA too?" Natasha said, sounding very upset.

"Not willingly... but yes. They were told if they did not do what they were asked, we would take away what was most precious in the world to them."

"Their daughters." Clint spoke up.

"Correct Mr Barton."

"You're lying! My father would never work for you!" Eva yelled outraged.

"Believe what you will my dear, but I am telling you the truth. Have Mr Stark test your DNA, you will see that I am not lying to you."

"What do you want Pavlo?" Steve asked the voice.

"I want Miss Romanova and Miss Nikolayev." He replied smoothly.

"Never gonna happen." Bucky growled.

"If you surrender yourselves to me, HYDRA will spare the lives of your friends."

"This is bullshit!" Clint said angrily. "HYDRA never spares anyone, let alone someone who could stop them. It's all a trick. We can't listen to this guy."

"Barton's right. I'm done with this!" Tony said angrily as he pulled the USB from the computer.

"What the hell was that?" Sharon asked alarmed.

"We've seen this kind of thing before with Dr Zola. He uploaded his mind into computers when he knew he was going to die." Steve said gravely.

"Are we sure this guy is dead? I mean he said he wasn't a machine, not that we want to believe a single word he says." Tony asked as he began searching for intel on his IPad. "But there is no record of his death."

"Maybe the stick was some kind of virus. When you plugged it in it took control of the computer, allowing him to communicate with us and access the webcam?" Natasha suggested.

"Highly likely." Tony replied grimly. "And that's exactly why I used a laptop independent of the internet and the rest of our system. The last thing we needed was for any of our files and data to be compromised."

"Good thinking Tony." Steve said as he clapped him on the back lightly.

"It happens occasionally." Tony smiled.

"Do we have the gear to run blood tests?" Eva spoke up. "I'd like to see if there is any truth to what he said."

"Me too. If what he said is true, the small amount that I did know about my family was all a lie." Natasha said sadly.

Enjoy the chapter, and Happy New Year everyone :)
