New story, hope everyone likes it.

First attempt at a Avengers fiction, but can't help myself, which means that I am not the owner of the characters, so I hope you are kind to me.

Enjoy!

Chapter 1

Running

The molecules in test #245 were still no different from the ones in test #244. The test subjects remained the same, there was little to no change in muscle mass, weight or height. What could she change next on the formula? Steve Roger's DNA code was changed dramatically after the experiment but no data was recollected before the procedure. She had reached another dead end in her research. At least she had her test subjects Bibbi and Diddi who were the only two mice who had given any sign of change.

Bibbi had being test #124, tested last month, had doubled in size and now run twice as fast on her training wheel. Diddi had being test #200, tested last week, she had presented the same changes that Bibbi had, but presented as well violent behavior. Dr. Erskine's notes had being right all the time; the subject had to be carefully selected for the serum had the desired effect.

PANG! PANG! PANG!

"Security Bridge on the East Wing. All class B and C personnel must evacuate the premises. Please leave all personal articles behind." The pre-recorded voice on the speakers voiced the instruction that had to be followed by all research personnel, which included her.

Dr. Barbara Morse stood up from her chair abruptly so she could reach her lab partner. "Come on Jessica, leave everything behind we need to leave"

Research tech Jessica Adams was scared as soon as she heard the siren. She looked like a deer caught in headlights. "Bobbi, what if they catch us?" Jessica asked fear getting in her voice.

"They won't Jess, I won't let anyone get you. You understand me?" Barbara asked and Jessica nodded and stood up slowly from her chair.

They exited their lab and could hear the panic in the people that were evacuating the premises. Barbara locked the door behind her with her ID card, she put the security code, ensuring that nobody was going to get in and mess with her research.

BOOM!

The sound of a bomb destroying a wall a bit more than 100 yards away from them alerted them to start running to the nearest exit.

Fire began behind them but that didn't stop them, they ducked and continued running to the exit.

A few men dressed in black and red uniforms approached them quickly and soon enough caught up with them.

They pointed their guns at them and both Jessica and Barbara put their hands up. Bobbi could see the eyes of one of the uniforms pointing at them. She knew very well who he was.

"Hello Bobbi" he said to her.

"Hi Paul" Barbara answered.

"Surprised to see me alive?" Paul asked.

"You should have stayed dead" Barbara said. Then in a very sudden moment she took his arm, bent it so he was forced to through away his gun and kicked him in the face so he would fall in the ground. Then, the other two subjects approached Bobbi so she took the gun from the ground and hit both of them hard on the head so they would fall as well.

"Ok, Jess, go, go, go!" Barbara yelled ordering her lab partner to run as fast as she could.

Jessica ran without looking back until she reached the exit marked door. She opened it and was received by a gun on her face.

"Please No!" She said, but it was too late. Before she could finish her pleading the man with the gun had already fired, killing her instantly.

Bobbi saw the exchange from afar, stopped in her tracks and decided to run to the other direction.

Paul, who recovered quickly from Bobbi's assault, was running behind her again. He stopped to aim and was successful, he had hit her on the shoulder, but the impact didn't stop Bobbi from running.

She was bleeding a lot and her arm and shoulder were killing her from the pain. But she could live through, it wasn't the first time she had being shot…probably wasn't going to be the last.

That thought in Bobbi's mind became more prominent when she fell to the floor. She tried to reach the gun on her ankle but was stopped by the foot that stomped on her shoulder. She cried in pain.

Paul put his gun on her head.

"This is for making me believe that you loved me" he said as he stomped her shoulder harder. "You should die like the traitor you are and when I kill you, I will kill Barton as well. You fell for him, didn't you?" And as soon as he was going to pull the trigger and Bobbi let out a low faint voice, a bullet crossed his head. He fell on her body seconds later. She would have picked herself up but couldn't, not only because of the constant pain in her wounded shoulder but the weight of her dead ex-fiancée was too much for her frail body to take.

Paul Allen, who had being revealed to be a double agent, was now dead. The satisfaction on Bobbi's heart was great. She could now be freed of his threats. "He is finally dead." She thought.

A figure fell to its knees. She felt the weight of Paul's body being lifted away from her. "Are you ok?" The feminine voice of the figure asked.

"Tasha?" Bobbi asked.

"My god!" Agent Romanoff exclaimed. "You are bleeding so much, let me call Barton"

Natasha Romanoff helped Bobbi turn around. She moved her hand to make sure her earpiece was working properly. "Barton, a little help would be appreciated"

"You should go, you are a sitting duck here" Bobbi told Natasha.

"Not leaving you Bobbi" Natasha said that and took her gun and shot three men that approached them.

Two minutes passed and then, the figure of Agent Barton appeared on the other side of the hall where they rested. He turned to them and started to run, finally kneeling down to check on Bobbi's wound immediately.

"Hey sport, you missed all the action, I think I won't make it for our date tomorrow, bummer" Bobbi said trying to sound cocky but fail as her voiced was full of agony in it.

Clint Barton, also known as Hawkeye inside the SHIELD premises brushed a tear that was falling out of her eyes.

"I'll take care of her Nat, you should go over to the South Wing" Barton said.

"No, I'll stay and clear you the path to go East"

"Oh God…stop arguing!" Bobbi exclaimed, by now the right sleeve in her white lab coat was completely drenched in blood.

"Fine, you'll cover us" Clint said scooping Bobbi on his strong arms.

Bobbi felt how the imminent sleep was upon her, she, suddenly, the only thing she could think about was sleeping on her bed. Closing her eyes seemed so tempting.

"Stay with me!" Clint demanded jerking her suddenly so she felt the impulse to open her eyes.

"Always" she whispered and closed her eyes again. That's all Bobbi remembered from July 27th, 2010.
