Hello sweeties! I'm AyaPie, and I'm here to give you a decent story about Big Hero 6.

BH6 is one of the sweetest movies I've seen last year. I love Baymax so much, he's so cute. Second favorite would be Tadashi. He is one hell of a brother! I guess that's what pursued me to write this story: I like Hiro and Tadashi's relationship. They're the sweetest brothers I've seen for a while now.

I guess you can say this piece of fic is an Alive!Tadashi AU. Don't misunderstand, though, I'm not in denial with Tadashi's death. However, this is an AU, and Tadashi's survival is really significant in the plot.

I hope I'll get at least a review till next week to be able to update this fic with motivation.

Please enjoy and follow this fanfic called Project:Baymax

Project: Baymax

Chapter 0: A Missing Heart

®® - Big Hero 6 belongs to Disney/Marvel. - ®®

San Fransokyo is a sophisticated place to live on, with its marvelous sights and surroundings, and an extremely peaceful sense of security. It was also one of the most advanced city there is so far, with the latest technology pieces being sold out at San Fransokyo's local stores. It was definitely in the country's top, and it can battle any other place in the world in terms of modernization.

San Fransokyo also has an institute for the extremely smart and inventive young minds, called San Fransokyo Institute of Technology, or SFIT for short. SFIT offers courses for the aspiring young inventors of the generation, and they would hold an annual showcase for people who hopes to enter the school. Showcasing the inventions scraped out of raw materials and a lot of brainwork, some of these would be enough to secure a spot on the institute, and the best of them all would even get a free admission.

One such talented student was Tadashi Miyamoto, who won first place at the showcase around two years ago for his prototype Baymax, a healthcare robot with a child-friendly design. Although the concept was halfway finished, Baymax did show some functions that gave the audience something to gape at. He also did impress Robert Callaghan, one of the leading experts in robotics. Callaghan personally congratulated him, and he promised that he'll finish Baymax before he graduate.

His adoptive parents were extremely proud of him. Though they had more than enough to pay for the tuition fees, Tadashi insisted that he will win the showcase to lessen their burdens. Even though they were extremely wealthy, Tadashi wasn't similar to those spoiled children who does nothing but to waste their parents' fortune. After all, Tadashi was extremely grateful that the couple adopted him after he lost everything. Just when he thought dying would be a more pleasant experience than living and knowing that he was the only one in the Hamada family that survived, Hana and Ryota gave him love, and that he was thankful for.

He buried the Hamada name along with the rest of his family. His father Tomeo, a genius inventor who was well-known throughout San Fransokyo with his world-class inventions. His mother Maemi, a genius, as well, who assists his father with the programming of her husband's invention functions.

The brainpower runs in the Hamada genes.

Heck even his brother Hiro learned how to read at the age of one-and-a-half, even though his speech were usually garbled. At two, he learned how to write, although his handwriting was pretty messy. Again, who would expect a two-year old to write like a professional, let alone write on his own? And before his third birthday, Hiro learned the 4 basic Mathematic functions, surprising the whole Hamada family at how Hiro was a child prodigy, and how he'd grow up to be better than Tomeo. Just a month before their whole life changed, Hiro assembled one of Tomeo's toy robots like it was a piece of cake.

It was an unfortunate event that Hiro never had the chance to grow up, as greedy people took what could be a future prodigy from this world. At how the cruel twist of fate took the three most important people in his life and left him alone until someone else picked him up.

The events were still fresh at his mind. He was only with his father Tomeo that time, until the car crash killed him, and almost killed Tadashi as well, not until the ambulance arrived. He woke up after a one-month coma to learn that his father died, and his mother and brother died in a fire that burnt their house down. It was a while before he get to stop wailing on his loss, as Hana and Ryota, a childless couple, made their way to the boy and offered to adopt him.

Tadashi glanced at the blueprint in front of him, with Baymax's design formulated in it as the ends were a bit burned. It was almost comical how the first Baymax his father made died along in the fire that ate his own house, and here he is, creating another one with the blueprint that miraculously survived.

However, he knew he wouldn't be able to make exactly the same one, as his mother programmed a chip for Baymax, a chip that supposedly made him almost human-like, as the chip was condensed with emotions such as care, worry, concern, friendliness and love.

It was as if Baymax has a heart. A heart that burned down along with his family. No matter how much he tried to recreate Baymax, he'll never erase the fact that he was left alone. How he wished he died as well.

San Fransokyo, however, isn't as perfect as everyone thinks. Although it's almost crime-free, there is the keyword "almost". Every midnight, a lot of thugs gather on a secret hideout to battle bots with a money bet. Although battling bots aren't really illegal, the betting part is.

A lot of tough-looking men and weird-looking women gathered around the ring, watching as the last man had his robot slashed, the winning guy laughing like a madman.

The announcer, a girl with strange clothes and highlights, raised her hands up.

"The winner, by total annihilation… YAMA!"

"Who's next?" Yama challenged, a smirk growing through his face. "Who has the guts to step into the ring with Little Yama?"

The people in the crowd hid their robots from plain sight, too cowardly to fight. However, a timid voice was heard, as someone raised his hand.

"Can I try?"

Everyone turned around to see a little boy, holding a little robot.

"I have a robot." He said, raising his small robot that's built out of magnets. "I built it myself."

The crowd erupted into laughter. The woman announcer stepped beside the boy.

"Beat it, kid. House rules: You gotta pay to play."

"Oh. Uh… Is this enough?" the kid held up a handful of money, as the woman accepted it."

"What's your name, little boy?" Yama asked curiously.

"Hiro. Hiro Hamada."

A/N: I hate myself for creating stories like this orz.

I hope you enjoyed reading! Did you enjoy Tadashi little angst part? Poor him, thinking everyone in his family died, when Hiro was just on the botfighting grounds. What do you think happened?

I might add the other characters soon. And btw I took Hiro and Tadashi's parents' name from Marvel's Big Hero 6.

Please read, review, favorite and follow! ~AyaPie
