Iron Man + Batman Crossover

Toni Stark is a billionaire, philanthropist, genius playgirl, known for her partying and not so sophistacated lifestyle. But what if she had had a best friend before this started? A best friend that had gone missing a few weeks after the deaths of her family and has been presumed dead for 6 years? What if, when he comes home, she is gone and trapped in her own personal hell and comes out a changed woman? Will these two best friends ever find their ways back to each other and confess their biggest secrets to each other before time runs out?

Disclaimer: I do not own either Marvel or DC… If I did, I would be rich and would probably make some of the fanfic stories I've read into like a miniseries on Netflix where each episode would be a different fanfic from either Marvel or DC… there is a million dollar idea lol.

Chapter One

"Mom, I don't understand why I can't stay here!" the six year old boy exclaimed to his mother as he followed his parents out to the waiting car.

"Bruce, we've told you this a thousand times. The Starks have invited your father and I over to go over some new contracts the government would like us to sign. And besides, you can't stay here by yourself, since we've given the staff the week off and since Alfred is coming with us." His mother said, helping him into his seat in the back of the car before joining her son and husband in the back as Alfred began to drive them to their private airfield.

"But it's going to be so boring!" Bruce complained, fiddling with the new Transformers toy his father had brought home a few nights before for him.

"That's not true. Maria and Howard have a six year old daughter that I'm sure you can play with while the four of us are busy. And besides, Alfred and the Starks' butler Jarvis will be there if you two will need anything." His mother said.

Bruce grimaced. "Ugh. Girl cooties."

He didn't notice it but Martha, his mother, and Thomas, his father, exchanged amused looks at his words. Neither of them could deny the fact that they thought young Stark heiress and their own son would develop a friendship that would survive through anything.

"Ah, Martha! Thomas! Welcome! Come in, come in," the woman said, ushering the two in, completely ignoring Bruce and Alfred whom had been standing to the side of the adult Waynes. "Please, make yourselves at home."

Bruce and Alfred were gestured inside by a man whom looked just as old as Alfred and whom had a young girl standing in his shadow peeking out at the newcomers in her home.

Her father came around the corner and although he smiled abesntly as Bruce and Alfred, he glared slightly at the little girl peeking out at him behind his butler.

"Jarvis, I thought I had said that she was supposed to stay in her room while our guests were visiting." Although he had spoken quietly, his voice had carried and had caught the attention of Thomas whom had heard of how Howard treated his daughter and stepped in quickly before something befell the young girl.

"I asked for Jarvis to bring her out to greet my son, Bruce, when he answered the door and before Maria came to greet us. I'm sorry if that was a little too forward of me, but Maria did tell us to make ourselves at home, did she not, dear?" Thomas asked over his shoulder as he came to just in front of Howard, blocking his view of his son and Howard's daughter whom had begun to slowly slip away from the escalating conversation in front of her.

Martha began to nod and put a small but fake smile on her face. "Why, yes, I believe that was said. Now, Toni, dear, why don't you and Jarvis show Bruce and Alfred your room and play together?"

Toni froze as all eyes landed on her, two sets of those glaring at her, which then caused her to beam sunnily but falsely at the young couple in front of her. "Yes, ma'am. Come on, Mr. Alfred, Mr. Wayne, you can follow Jarvis and I while our parents discuss their business prospects and political views."

Bruce and Alfred said nothing as they followed the other butler and his young charge down the hall and away from the polite, subtle arguing voices behind them.

They came to a door that was closed but before they entered, Jarvis stopped and spoke. "Miss Stark, Mister Wayne, I shall return in a few minutes with a small snack to tide us over until dinner. Mr Pennyworth, would you like to join me?"

"I would love to. Lead the way." Alfred said. The two british elderly butlers walked down the hall and towards the ktichen. The two six year olds exchanged glacnes, shrugged, and Toni opened her room to reveal blueprints and inventions spread across every surface of her room with a telescope sticking out of her window and with posters involving biology, chemistry, and calculus, the room was practically a nerd haven.

Toni had immediately walked over to her desk and picked up a screwdriver there and began to fiddle with something in front of her.

Curious, Bruce drew forward and peeked over her shoulder to see Toni had begun to attach the last leg to a large robotic dog.

"That's cool!" Bruce said softly, not wanting to speek too loud and disrupt her concentration.

Toni wasn't bothered thought and sent him a small smile over her shoulder.

"Thanks! This is my robot dog and my best one I've built as he has been uploaded with real dog guard tendencies and movements. He doesn't shed, bark, or need basic needs to survive." Toni said to him, picking up the heavy robotic dog from her desk and setting it down on the ground on it's legs. "It is also voice controlled."

"Really?"

"Realy."

"Show me."

Toni cleared her voice and spoke clearly. "Maximus the III, you are hearby to protect Bruce Wayne to your upmost ability and those that he deems his family. You are to follow his commands as if they were my own. Bark twice if commands are understood."

The robotic dog barked twice just as the door opened after a quiet knock and revealing Jarvis and Alfred, the former holding a tray of snacks for them all.

"Alfred! Look at what Toni gave me!" Bruce exclaimed, running up to his butler and taking his hand, turning to pull Alfred with him only to stop short as the robotic dog had followed his footsteps and now was just standing there with eyes that glowed blue and watching Alfred around his new charge.

"Maximus the III, this is Alfred, this is Bruce's butler and caretaker, he means Bruce no harm." Toni commanded. She turned her attention to the Gotham visitors. "If you speak and declare whom you are, and repeat those commands with your parents, Maximus the III will protect you with the best his processors allow him."

Bruce and Alfred then proceeded to introduce themselves to their new addition to the Wayne household. But Alfred had a question to ask the young Stark heiress. "Miss Stark, how is Maximus the III supposed to protect the Masters?"

"Well, for one, Maximus is able to call 911 if it is needed in order to call the police during any type of emergency. And two, he has his own weapons system that aims to harm, not kill, the attackers/intruders unless aboslutely necessary."

Alfred's eyes widened slightly at her words and he examined the robot dog more closely and saw that there could possibly be weapons in this robot that Toni had armed it with.

"Well, then, Miss Stark, if Mr and Mrs Wayne have no problem with us taking him home with us, then we shall be honored to have Maximus the III apart of our household."

And that day as Toni Stark and Bruce Wayne grinned at each other over the excitement of having a friend that treated them like they were just Toni and Bruce, not children of two of the most richest families in the world. And they knew that their friendship would be one to last through anything… But not even they could have foretold what would happen in the many years to come.

That day was the day that Bruce Wayne aka Batman and Toni Stark aka Iron Woman would have their lives tied together with the string of Fate.
