Asimov James Banner-Stark was created in a petri-dish, grown in a test tube like a science experiment. A collection of hired geneticists mixed the sperm of both his fathers along with an artificially created egg, to make him. He was the first of his kind to survive, a child created in a test tube, a child created from the sperm of two men. One of which was radioactive, and the other, a man who was only alive because of a machine in his chest.

As odd as Asimov's birth was, it would be a lie to say that he wasn't loved. Because that was wrong, he was immensely loved by all of the Avengers and his fathers. Bruce Banner thought he would never have a child, and Tony Stark never thought he could create something that didn't cause destruction. Asimov was the answer to everything both geniuses ever wanted. He was their miracle.

Jimmy was at a crime scene when he first got the call, his Stark Phone began buzzing in his pocket and ringing loud enough to annoy the rest of the Team who were at the crime scene. Gibbs gave him a pointed glare and Jimmy blushed scarlet as he walked off to take the call. The young man whipped out his phone and had a double take at who was calling him, Tony Stark...his Dad. He'd had barely any contact with his Dads for three years, not since he moved to D.C and joined NCIS. The only times they called were on birthdays and such. Never out of the blue...never like this. Jimmy instantly accepted the call and held the device to his ear.

"Asimov? It's me."

Jimmy stiffened when he heard his Dad's voice filter through the call, his voice sounded tired and strained. His breath coming out in short pants.

"Dad? Why are you calling me? Where are you? Where's Baba?"

Jimmy hissed worriedly, was he calling him in the suit. Dad never called any of them in the suit unless the need was dire. What the hell was happening!?

"Asimov...just- just listen to me, okay? You know that I left the company in your name, right?"

The company? He could possibly be dying and his Dad wanted to talk about ownership of the company? Just how serious was this?

"Y-Yeah Daddy. You told me when I was twelve."

Jimmy stammered softly, his voice instantly slipped into calling his Dad, 'Daddy', just like he had when he was little. He didn't want to lose his Dad, he couldn't. His Dad was Tony freaking Stark.

"Good, that's good. Y-You know I do love you, right? It was so fucking stupid of me not to tell you and Bruce that enough. I'm so sorry, kid."

"Daddy...shut up. I know you love me, Baba knows that you love him too. You aren't Howard, Daddy. You were never Howard. You were so much better."

Jimmy snapped loudly, cutting off his Dad as he clenched his teeth. His Dad was amazing, everything he could've ever wanted. He was nothing like his own Father, Howard Stark was a douche bag. While his son, Tony Stark was anything but. Sure, he spent too much time in his lab sometimes, sometimes he would drink too much, and sometimes Jimmy would fall asleep worrying if his Daddies would come home that night. But he wouldn't have traded that for the world.

"Thanks, kid. Everything will be fine, I promise...tell Bruce I'm so-"

The line went dead in the middle of his Dad's sentence along with the sounds of an explosion. Jimmy instantly began yelling into the phone, praying that his father would pick up. His Dad wouldn't do this to him, where was his Baba?

"Daddy! DADDY! PICK UP THE FUCKING PHONE! DON'T LEAVE ME LIKE THIS!"

Jimmy shrieked, before letting the phone slip from his fingers. He dimly registered the fact that his made a muffled thump as it hit the grass below his feet, but the young M.E didn't care. He just felt utterly and totally numb as he walked back towards where the Team was. When he got back, he saw that people were talking to him, he saw their lips moving but no sounds were registering in his numb mind. He had to get home...he wanted to go home.

Suddenly like an ocean, a wave of grief washed over him and finally his feelings returned. He felt sick, literally empty, and yet his stomach threatened to empty its contents. He knelt over nearby tree's roots, struggling to breathe and fighting the tears that had sprung into his eyes. His legs buckled underneath him and he fell into a kneeling position.

His Daddy...Oh god...he had to call...to call someone important. Uncle Steve? Uncle Clint? He still didn't even know where his Baba was!

Jimmy jerked out of his stupor when he felt a familiar stinging sensation on the back of his head. The young man blinked up at Gibbs owlishly. He had slapped him on the back of his head.

"What's going on, Palmer?!"

Gibbs barked roughly, his voice edged in concern. Jimmy blinked away the tears that prickled in his eyes as he stared blankly up at the Team, they were all looking at him in confusion and concern in their eyes. McGee and Tony were the only ones who kept him semi-upright. What was going on? He almost smiled hysterically at the thought of that question. Turn on the news, they'd figure it out soon enough.

"My Dad...I have to go...s-sorry."

Jimmy stammered as he tried to push his way up and out of their arms but Gibbs' strong hand on his shoulder, stopped him.

"Do you want one of us to drive you home, Palmer?"

Jimmy didn't answer as he stumbled forwards, pushing out of the hands of his friends. He shook his head blearily. Smiling forcibly when someone shoved his dropped phone into his hands. He dimly noticed as someone helped him into an NCIS van, his mind floating off to another time, another place.

'Daddy! Baba! Look!'

The Avengers smiled as they all turned to the grand piano in the corner of Tony's sitting room. All the Avengers were dressed casually, slumped around a few couch, Bruce and Tony both turned to look pridefully at their young son, who was sitting in the huge seat of the piano. Bruce's brow furrowed worriedly as he watched their little boy, the toddler was barely three.

'Tony, are you sure that's safe?'

The billionaire just rolled his eyes and nuzzled his face into his husband's neck. Bruce always worried too much, he would wrap Asimov up in bubble wrap if he could. Or if Tony would let him.

'Of course it is. Just let him play on the thing if he wants.'

Bruce just nodded, but he watched his little son play on the piano. Suddenly he froze as he heard what was coming from the piano, instead of doing what a normal toddler would would do and just bang on the keys to his heart's content. Whatever Asimov was playing on the piano actually sounded like music, the same kind of music that Tony would play whenever he sat down at the piano.

'Have you been teaching the kid, Tony?'

Clint asked as he watched the little boy's hands fly across the keys like wildfire, but Tony was just gaping at the child in shock.

'I haven't taught him anything.'

'So he learned that on his own?'

The only answer to Natasha's question was Tony's shocked head shaking. Clint just rolled his eyes as he looked at the stunned parents.

'Oh don't be surprised, you're both geniuses. Why wouldn't your son be one too?'

Jimmy smiled at the memory and he wondered again why he hadn't tried to pursue a musical career, music was his first love after all. But instead he had decided on a scientific career. Maybe he could start on his music again? Jimmy looked up as he heard Tony whispering under his breath to Gibbs.

"Wow boss, you aren't going to believe this."

Gibbs' face darkened and he rolled his eyes at the worried and hushed one of his senior agent.

"What, Dinozzo?"

"Tony Stark is dead."
