Chapter One: From the Ashes

Hiro Hamada is exhausted.

Big Hero 6 (that's what they are calling themselves) were stopping criminals all night. Ever since the team started, more and more of Japan's most wanted have been coming out with their own advanced technologies. Of course, Hiro can always figure out the super villains' flaws and/or the team just beats them by force. But still, its a lot to do in one night.

He trudges into the Lucky Cat Cafe just as Aunt Cass is closing. Baymax follows behind him, and is, of course, going all nurse on him, "Hiro, I suggest one half a liter of clear water and 10 hours of sleep to be fully rested."

Hiro just rolls his eyes and sits at a booth, "Go upstairs, Baymax. You're done for the night, buddy."

The white robot nods and begins his way up, since he already left his armor in the garage like Hiro.

Cass watches the inflatable doctor make its way up the steps and then comes and sits next to her nephew, handing him a sugar donut, "Rough night, sweetie?"

He exhales, "No, just busy."

She examines her near son, "You do know that I support your genius little butt in everything it does, but I want you to be careful with this whole superhero thing."

Hiro leans in against his aunt and closes his eyes for a moment, "I know Aunt Cass, we've been doing this 8 months already."

She kisses his scruffy head, "I am a terrible mother for letting you do this, aren't I?"

"Yes."

They both laugh and split the donut.

Just after Hiro takes his last bite, the phone rings and Cass gets up to get it. She walks to the counter, untying her apron on the way. Picking up the phone with a smile, she happily greets the other line, "Hello?"
Hiro watches as her smile soon fades away and she turns her back to her nephew, "What?"

She listens.

"I… I don't understand."

She listens a bit longer.
"But… are you sure?"

She listens for a short period this time.

Her back is turned to Hiro, but he sees her takes the phone off her ear for a second, obviously to take a deep, shaky breath, "Um, okay. We'll be right there."

Cass turns back to her basically son, tears already drying on her face, "Its about Tadashi."

Hiro catches his breath, No. It can't be about him. I thought I was done with all of that. "What? What is it?" he asks impatiently.

She pulls him up by the arm and pushes him out the door, "I'll explain in the car."

His exhaustion replaced with unbearable apprehension, Hiro taps his fingers on the windowsill of the car. He simply stares out the window in a daze after what Cass just told him. Apparently, a construction team was finally rebuilding the facility where the entrance show was, now that they had all the permits. They found an encasing of Hiro's microbots on one of the floors that was sealed shut after being burned by the fire. Chopping it down with an axe, they saw what was inside.

A person.

Cass said that on the phone, they described him as a 19 year old, black-haired boy. He was found in some sort of coma and they are taking him to San Fransokyo Hospital.

This is too much information for Hiro to grasp. Sure, he had graduated high school at 13, and his professors extol him for his ability to analyze complex situations and figure out their solutions. Yet, the idea of his brother being alive… after all this time… is just too much.

He glances over at Aunt Cass, her hands gripping the steering wheel so tight that her knuckles are pale. She is trying to keep a calm face for her nephew but it isn't working. Hiro sighs, it must be worse for her than him. She probably feels like the worse mother in the world, one of her children is dead (as far as they know) and the other has become a crazy superhero, that's not usually the dream parents have for their children.

They pull into the parking lot of the emergency care portion of the hospital and rush through the doors. Cass holds Hiro's hand firmly. I'm 14 years old and I fight deadly criminals every week but I still need to hold my aunt's hand when I get nervous. But looking cool is the least of Hiro's worries at the moment.

Cass avoids gurneys and doctors rushing about and reaches the front desk, "Excuse me, I was giving a call that there was 19 year old boy found that might be my son, Tadashi." Usually Aunt Cass says that the boys are her nephews when she first tells people but today she doesn't.

The nurse at the desk looks through the computer, "Yes, he's in room 4032, on the fourth floor." Cass thanks her and leads Hiro toward the elevator. "Hey," the nurse calls after them. Cass turns around confused, "I'm a mother too. May God help you." The aunt-turned-mother smiles and nods before catching the next elevator.

Once they are alone in the elevator, Cass begins to cry, "I'm so sorry that all of this happens to you Hiro. You're just a boy."

Hiro frowns and puts a hand on her shoulder, "It's not your fault Aunt Cass…" he doesn't know what else to say. He wants to make her feel better, but he can barely catch his own breath. What if Tadashi is alive? Would he come back to the university? Or would his brain be so damaged that he can barely speak?

The door opens on the fourth floor and Cass tries to contain her sobs, "Let's go."

They walk the hall in silences until they come to room 4032. A doctor waits outside, the door is closed, Hiro attempts to turn the nob but the man gently gestures for him to step back. "Why can't we see him?"

The old doctor slightly grins, "We first called you here because we wanted you to identify him since he was in a coma?"

"And what has changed?" Cass holds her arms close to herself.

He frowns, "Well, Tadashi has come out of the coma and we don't understand why. He awoke and is very confused as to why he is in the hospital. All his vitals are fine and he has no brain damage, we'd like to run more tests before he sees anyone."

"So you are sure he is Tadashi?" Hiro inquires.

The doctor shrugs, "He had a wallet on him. We saw his license."

The aunt and nephew exhale but don't dare to smile. They are happy, but they just don't know what to think right now. It's all so sudden. Cass gets a bit closer to the doctor, "Listen doc, you are going to let me in to see my son or God help me I will shove some hospital food down your throat until you gag." The doctor is about protest but Aunt Cass adds in one more thing, "Also, my boy right here is Hiro Hamada. As in, the leader of Big Hero 6 and he will hold you out the window until you cry like a baby."

The doctor looks at Hiro, probably realizing that he has seen him in the newspapers and opens the door for the two to enter, "Just don't put any stress on him."

The lights are dim and the boy in the bed looks perfectly healthy. Tadashi sits on the cot, arms crossed, eyebrows furrowed in annoyance. He looks far better than what you would expect for someone who just came back from the dead.

The young man's eyes perk up when he sees his brother and aunt come into the room, he attempts to get up to greet them but he leans back, realizing that the doctors hooked him up to random machinery for unnecessary reasons. "Boy, am I happy to see you guys, these doctors don't know what they're doing. Baymax could do a better job."

Without responding to his joke, Hiro runs up to the hospital bed and throws himself against his big brother in a hug. Tadashi, a bit confused, embraces him and pats his back. Hiro sniffles, wipes tears from his eyes, and steps back so that Cass can give her eldest nephew a quick hug and kiss.

Tadashi is even more bewildered than when he first woke up, "Guys what happened? Why am I in the hospital?"

The two exchange expressions. Hiro tries to speak, but when he opens his mouth, his tongue is dry. Cass sits at Tadashi's feet on the bed, "Sweetheart. Don't you remember the fire?"

The boy's eyes widen, "Callahan… and the explosion…"

His aunt nods, "That was eight months ago. You've been in a coma."

Tadashi frowns, trying not to get himself overexcited. Hiro is surprised as to how calm he is. "But that's not it. There's something more isn't there? What aren't you telling me?" Hiro still hasn't said a word. "Come on baby brother, speak up."
Hiro locks eyes with him, "You… I… we thought you were dead. There was an explosion and your body wasn't found in the debris until today."

"So you're saying that you guys thought I was dead?! All this time…" Tadashi shakes his head and gestures for Hiro to come closer. The fourteen year old falls onto the bed and buries his head deep into his brothers chest, crying like he's five again. Tadashi strokes his messy black hair, which hasn't changed a bit. The only thing he can say is, "I'm sorry."

Aunt Cass is also tearing again, "Oh baby, there's nothing to be sorry for. We're just happy to have you back. Now, lets go home."

After the family composes themselves they leave the hospital room. The doctor tries to stop the three as they exit but Hiro just glares at him, "You have no reason to keep him here. He's fine."

The doctor glances at Tadashi who shrugs, "I'll come back tomorrow for some follow up tests if you want but I have a robot that does this sort of stuff for me."

And with that, a family is reunited. But a new story has only begun.

So. My favorite thing in the world: comics. Particularly Marvel. My second favorite thing: animated disney movies. When these two things come together, it is magical. I hope to make this maybe an 8 to 10 chapter story if I can find the time.

If you guys are marvel fans I also have a Spider-Man, Avengers crossover called Face Behind the Mask (by me, Paranatural). So this is officially my second fan fiction ever! I hope you guys enjoy. I was originally planning on doing some Young Justice fics but who knows...

ANYWAY: Tadashi is alive and they have to find out how he survived all that time and there is a new villain rising. However, the main conflict between Tadashi and Hiro is his disapproval of Hiro's superhero lifestyle (it's kind of my take on all this Tadashi overprotective stuff). Stay tuned... I don't know when this will be updated.
