SONG OF THE CHAPTER: Little Girl Gone - CHINCHILLA

Today was their first day of training after regrouping. None of the others knew about Stygian's newfound ability. She'd managed to keep it at bay since being there but knew it would be difficult in training. Part of her wanted to flex her abilities.

Rarely did the full group get together to train so it was an odd occasion. They had gone through rounds of battling each other.

Stygian had beaten Steve, Thor, and Tony in these fights, just by using her strength and tactics. Next, she was up against Natasha. Now it was going to get interesting. This was the last battle for the entire team so everyone stood around and watched.

"We've got an audience now. You gonna pussy out?" Y/n smirked getting into position opposite the blonde.

"Why? Regretting going up against me already?" She quickly responded.

"Nope, just checking to see if you wanted to be spared." She laughed.

"Oh please you know I'm just as good as you."

"Just you wait," y/n muttered under her breath.

"You guys ready?" Tony asked waiting to shout the cue for them to start.

"Yep," they said in unison

"3, 2, 1, go!"

They circled for a second before Stygian made the first move unexpectedly.

She threw a hard punch spinning Natasha around. The blonde was expecting a false move and was shocked when the punch actually landed.

Then the killer kicked the back of her knees, knocking the girl to the ground. Natasha grabbed her by the ankles and swept her off her feet.

Stygian quickly pinned the girl by the top parts of her arms, until Natasha pulled another surprising move. She bit the girl on the arm and backhand slapped her across the face.

"What is this a catfight?" Stygian laughed mercilessly and stared daggers at Natasha.

The blonde only returned the look and kept trying to punch her.

Stygian let the punches hit her only smirking at the other woman.

Natasha was furious and wasting all her energy on throwing the punches thinking it was getting somewhere.

"I thought you knew better than to waste your energy on worthless punches. You forgot how strong I am," Stygian laughed.

"Oh really? Cause you sure as hell aren't showing it. I think you're weak and it's all just a show," Natasha spoke blinded by rage.

Stygian was also infuriated and grabbed the girl's wrist harshly whilst she was mid-punch. Natasha paused for a second in shock. Y/n used this to her advantage and threw a punch directly at her jaw causing a cracking sound and for blood to fly out of Natasha's mouth. The crack had come from Stygian's knuckles and the entire team gasped as they watched.

Natasha stumbled back holding her jaw wiping the blood off her mouth and looked at it. She laughed viciously and looked up at Stygian. This was no longer Natasha. Her pure rage had taken over and she was in fight mode.

When Natasha flew at Stygian trying to use her skills to sweep her off her feet and get her into a headlock, she was dumbfounded when it was only half working. The girl was in a headlock but seemed totally calm. She twisted Y/n's arm in hopes of almost breaking it so she would give up. She knew her anger had taken over but she had lost control completely and didn't care.

Stygian could feel her arm twisting and twisting more. She was letting it happen. Waiting for the perfect moment to put on her final act.

When she heard her arm begin to click she could tell Natasha was already surprised she hadn't given in.

Finally, now was the perfect time to start a fire. Literally.

Her arms started heating up, so much so Natasha had to take her hand off to stop her from burning.

Seconds later the rapid flames had started to show.

This earned huge gasps from the team and they started to mutter about what to do. While they had set no boundaries they hadn't expected this to happen.

Natasha was trying desperately to not let her jaw hit the floor. She thought she was dreaming.

Stygian's eyes had changed to a fiery red. The flames travelled up her arms as she steadied her position. Natasha took small steps back trying to think of what to do. She quickly took out a knife from a pocket and pointed at the girl.

Stygian strolled over towards Natasha, throwing a fireball and catching it in her left hand. When she got close enough she pressed the fireball into her chest, straining her posture trying to take control of the power. She could feel it starting to burn her but had to keep going.

Knife still pointed, Natasha started to fear the killer, for the first time in her life.

Stygian held her flaming finger up, smirked at the girl, and put the tip of her finger onto the tip of the knife, letting the flames infect the knife. It quickly heated up making Natasha drop it.

Y/n picked it up and started flipping it in her hand. "Still think you're the strong one?" She smirked.

"I'm not giving up."

"Cute. Good luck," Stygian cocked her head and gave a wicked smile whilst forming an energy ball.

Natasha took one step forward before the energy ball came flying towards her, temporarily knocking her to the ground.

Seeing this Stygian let the flames disappear just as quickly as they had shown themselves, leaving Y/n with huge patches of burn marks.

She hissed when she started to move after they had gone.

She ducked under the ropes and slid out of the ring grabbing hers and Natasha's towels and water. She took a sip of hers and slid back into the ring to throw the blonde her stuff.

Natasha was suspiciously quiet throughout this. Y/n raised an eyebrow when she looked at her to try and judge her reaction. It was like nothing she had seen.

"And you decided to keep this quiet, why?" The blonde girl asked slowly trying to get up knowing her stomach will be badly bruised.

"I suppose it never came up," she shrugged.

"This is a pretty serious thing to just not bring up."

"It hadn't become an issue so I didn't need to mention it," Y/n spoke in an icy tone, almost biting back at Natasha's comment.

" I think we might need to run some tests," Bruce spoke looking at Tony for approval.

Stygian began to walk laps of the room casually with her hands behind her back.

"Blood pressure: 200mmHg, body temperature: 345°c, heartbeat: 263 beats per minute. My DNA has been mutated enough due to a high-end energy source to allow me to control the heat of my body and set myself on fire. If my energy levels are strong enough I can become a human version of the sun. My entire body is alight with flames. Due to the extreme doses of serum within me, I don't scar when I get burnt. I can feel it but it doesn't stick around long." She spoke whilst pointing at the already disappearing burn marks. "Thanks to the scepter and hydra they created a machine that could emit extreme levels of radiation through any form of life. Their project wasn't as successful as they thought, however, as it self-destructed after my second round. This experimentation was by choice. Everything else, not so much."

"Who were you with? You couldn't have set this up yourself?" Steve queried.

"Ran into some old friends from a while back. They found it after the battle in New York. The sceptre was gone but that machine definitely wasn't."

"And where are they now?"

"Dead. The lot of them." She stiffened. "The base was ransacked when I last paid a visit."

"Y/n would you mind coming up for more testing in a bit? I think me and Bruce want to explore a bit more than your old friends did," Tony asked.

"Sure."
