Capture

Chapter 1
Captured

“Agent Sapphire, bravo team is in position.” 

“Copy. Hold position and wait for my mark.” Emma muttered back through the coms. 

Emma Warner, agent of S.H.I.E.L.D since she was 16 years old. Her grandparents worked along side of Stark during the first beginning stages of Shield. They helped run the testing of the super solider serum. They passed before she could meet them. But what many people didnt know was that they were enhanced human beings. Mutant genes. Her grandmother could control earth elements and her grandfather had knowledge absorption. They kept these things under wraps and had died with out anyone knowing the truth. 
Her mother died during childbirth, and her father died in a tragic explosion when she was very young, and that is where her life changed. Her father didnt have the mutant genes, and it was thought that Emma didnt either. 
But she survived the explosion somehow, though she was in a coma for about 2 months before she woke up. Shield took her in and cared for her. At 8 years old she was already showing signs of being at the same level of genius that her grandparents and father had, but didnt know any other signs of behind enhanced. 


At 10 years old is when she first showed signs that the explosion that took her fathers life and had placed her in a coma, had given her some extra abilities. The doctors of shield had always been curious why the child had miraculously healed so quickly, and why the young girl never seemed to get sick. Running tests one her it was discovered that she was an enhanced with mutant genes and the explosion seemed to have brought it forward. And during her physical training, she always seemed to out perform everyone else by a large amount. Whenever anyone tried to match her, her team mates would whisper that she was not like everyone else.
One day during training, one of the older kids had come up and started to push Emma around. A few more kids joined in and when one of the boys who had picked up a bat swung at her, she threw her hands up in front of her and a blue shimmery force field had blocked the blow. 

 Eyes wide, some in awe and others terrified, that was the moment that changed for Emma. Shield took her away and hid her. They discovered that the explosion that happened when she was young, was a radioactive explosion. Her father had been working on the tesseract, doing testing with it and had went back in for a little bit one day to do some work on it and it had backfired, literally. They think she naturally had the shielding ability and enhanced senses, but the tesseract charged explosion altered everything slightly and amped up her powers and gave her extra powers. 

 They found out that some of the things that her father was working on and the blast from the tesseract combined had absorbed into Emma. Along with her enhanced stamina, strength, senses and speed and already being able to create forcefields, the extra power gave her the ability to create protective force fields that were customizable to suit any situation and be able to shield others. She could also produce energy blasts from her hands that seemed to resemble the power of the tesseract.

 More recently she discovered she could also heal others as well as her own body, but she discovered that it zapped her energy quickly. She had knocked herself out for a solid 3 days once when she had healed Agent Romanoff during a mission that Nat had gotten shot. Natasha Romanoff was one of her mentors and Emma looked up to her as a big sister. They had been ambushed and heard Nat get shot over the coms and when Emma had finally got to her, she had started crying and was desperate to stop the bleeding when her hands started glowing. The wound started to heal very slowly when Emma realized what was happening. Putting all of her energy into healing Nat, she blacked out and woke up 3 days later. What they think happens is that she is transferring some of her own life energy into the person to heal them. Essentially letting them borrow her healing ability.
 Emma is now a 30 year old badass agent of shield. Right up there with Clint and Nat. That team is beyond deadly. Emma was given the code name Sapphire when she graduated as a full fledged agent. Her name was due to the color that her eyes would glow when she used her abilities. 

 Currently Emma is on a simple intel mission. They were in Russia at an old nuclear base. It was some potential terrorist group that was building. It was her and her teams job to take out the group before they could get themselves known. And it was an area that the government technically couldn’t touch. 

“Alright, Bravo team, move in.” Emma spoke over the coms. Their role was to provide a distraction so she could sneak in and destroy the facility included the group inside. 

“Copy. Moving out.” She heard one of the agents confirm. She crept up the other side of the base. Going in through the window that she had previously scope out, she landed slightly on the other side. 

 Her head came up and was looking around for any movement. She could hear the running of people and the yelling about an attack. Smirking to herself she took off down the opposite direction. She found the room she was looking for and quickly disabled all security measures. Quickly hacking into their mainframe, she proceeding to delete any all files and administered a virus to delete everything else. Next she left the room and started to plant bombs in the planned locations.  

“How are things going guys?” She asked into the coms. “Going as planned.” Agent Felix called out. He was one of the agents that she tended to do these missions with. “Almost done with my side, then we can get out of here.” She spoke back. 

“Copy that.” 

Suddenly there was bullets being fired at Emma. “Holy Fuck..” she ducked down quickly, bringing her shield up around her. More shots fired and bounced off her force field. “Nice try fellas.” She shouted back. Stepping from the corner, she lowered her shield for a moment to fire back at the group that found her. But when she stepped around the corner, she realized this didnt look like a normal terrorist group. These were fully decked out deadly looking soldiers. 
Turning around she gave them a small wave and decided to turn and leave. “Leaving so soon?” She heard spoken from behind her. Turning around, “yeah, i would hate to overstay my welcome.” She shrugged. 
 “Why don’t you stay? I insist.” Looking at the mysterious figure standing between the group of guys who had been shooting at her.  He was dressed all in black with a mask covering his face. She had pulled her shield up around her, waiting for the opportunity to escape. Keeping her shield up this long used to drain her energy, but now its almost second nature thankfully. It’s when she is consciously shielding herself and others separately that it still wares her down. 
The other soldiers were still there when the guy in the mask suddenly threw out a puck shaped object that landed on the floor near her and it sent out a weird pulse before she could react. She threw up her hands to send a energy blast at them when she felt odd and her powers suddenly gave out. She threw up her hands to try and blast her way out of the room and still, nothing happened. 

 “Ummm….. guys, i may be in trouble.” She whispered out to the coms, not knowing what the heck is happening. Looking to the circled object, it was pulsing blue and sending out a wave of energy every 10-15 seconds. 

 She heard a chuckle and she glanced back up to the masked guy. “Like it?” His voice rumbled. “We were able to get our hands on some of the work from the tesseract. And this nifty thing here, it negates the power of the tesseract.  And one of our scientists who happens to do some ‘testing’ on mutants added in some extra juice that just so happens to mute those powers as well.” He says with an evil chuckle. She glanced around, trying to keep her face controlled, trying not to show how nervous she was. “That whole terrorist thing, was just a ploy to get you here my dear.” Emma gulped at that. Now she knew she was in trouble. 

 “It’s very cool, but forgive me if i don’t show my excitement.” Emma snarked back. He crossed his arms over his chest and tilted his head at her. Nodding his head at two of the thugs next to him, they advanced on her quickly. They assumed since her powers were out that he was useless. But what they don’t realize is that Shield had created a chamber that caused her powers to be muted. And she trained in that every day with both Clint and Nat. She learned from the best. She even had a weight set in that room so she could build muscle and stamina naturally and get used to working without her powers. For exact reasons like this. 

“Lets go fellas, i was itching for a good fight.” Pulling her favorite weapons out from back, a pair of sai’s. The three pronged daggers were her favorites ever since she picked them up when she was starting to learn weapons handling. 

 The three engaged in combat, Emma taking out both of them in no time. She turned around to stare down the rest.  “Satisfied?” She spoke. She gripped her blades in her hands and took on a defensive stance. The rest of the group, about 4 more guys, decended on her. She felt a solid punch to her side and that gave them the opening to land a kick to her chest. Flying back into the wall, they pinned her to it and held her in place. WHen she started to break free she felt a knife against her throat. Stilling, breathing hard, Emma stopped the fighting. 
Looking at the circler piece that was still preventing her from using her powers, she let out a huge breath of defeat. Trying again on her coms she tried to yell into the ear piece now, “I need extraction. NOW! I am in major trouble guys. Anyone copy?” Not caring if the guys in front of her knew she had communications on. 
“Sapphire! What’s happening? Where are you?” I heard Felix shout back.  “Sunshine.” She spoke back. The guys gave her a weirded look, but that one word told her team everything. That one word meant she was captured, without powers.  

“Shit!” She heard back. “Im contacting Fury!” Felix also said. She knew that they weren’t going to get to her in time. She just hoped that they could get to her quickly enough. Nat and Clint were going to be pissed at her, and Steve Rogers. 
The mysterious guy walked up to Emma and pulled out a syringe. Her eyes not paying attention to that and just glared, knowing what was coming. She was pulled from the wall and had her hands cuffed behind her back. Holding her in place again, he injected the fluid into the side of her neck. 

“Sleep well miss Emma. We will be spending lots of time together.” 

“Go to hell you asshole.” She whispered out. Before she went all the way under, she was able to activate her hidden SOS tracker. It’s undetectable on scans and takes a certain sequence to start it. They are implanted under the skin, typically in that low back area anticipating being cuffed or tied up, in case they are stripped of clothing. Hoping that once she was out of this place, it would send out the SOS beacon and can be rescued quickly. 

Last thing she heard was a dark chuckle.
