Chapter 1

New encountering's

Sweat was pouring off his brow.

His heart was rapidly thumping inside his chest, it ached and burned with exhaustion.

"Baymax!"

Hiro Hamada raced through the streets of San Fransokyo. He was chasing after his older brother's invention, a squishy balloon like robotic nurse named Baymax. All the fourteen year old was doing was working on his megabot when Baymax just got up and left saying he was going to find where the tiny robot wanted to go.

'I didn't think he was serious!' Hiro thought. The tiny robot was in fact one of his microbots. And the thing was broken, microbots are only attracted to other microbots, and the rest was destroyed. So it was the only explanation. But now here the shaggy hair teen was, chasing after the white plush like robot.

Hiro was shoving through the crowds of people in the city. "Baymax what are you doing!" he called.

Baymax, who was down the street, continued waddling in the same direction. Not even looking at his surroundings, just focusing on the microbot in his hands. The white robot then turned a corner into an alley.

A minute later Hiro shot past the same corner, falling and slipping as he tried to course correct in mid run. "Baymax wait!" The young teen yelled sprinting down the alley. When he reached the end Hiro's eyes darted back and forth, searching for the white robot.

He quickly caught sight of Baymax and luckily he was stopped, but was in front of some warehouse. The young teen didn't waste a second to run over to the marshmallow robot.

"Baymax are you crazy! What are you doing?" Hiro breathed heavily resting on his knees.

"I found where your tiny robot wanted to go." Baymax answered.

The shaggy hair teen grabbed the bowl the microbot was in from the robot. "Baymax I told you it's-" Hiro stopped his sentence when he realized the microbot was rolling forward. He cocked an eyebrow. 'That's weird...' It was like the microbot was rolling toward the warehouse. To test this the young teen moved it to the side, but this only resulted in the tiny robot rolling back in the same direction, toward the warehouse. 'Something must be in there.'

Hiro wiggled the chain that kept the doors shut. "Its locked."

"There is a window up there." Baymax suggested looking upwards.

The shaggy hair teen smiled determinedly. "Great come on." He then pulled Baymax under the window. "Alright just hold still." Hiro said and began climbing up the soft robot.

"Careful a fall from this height can result into serious injury." Baymax commented.

"Yea I got it." the young teen responded pulling himself inside. When Hiro was fully in he stood up and looked around. 'It just looks like some abandon warehouse.' he thought. But his microbot was still moving forward. Hiro's eye then catches sight of a stair case. "And that's my way-"

He quickly stopped himself as a loud noise came from behind him. The young teen snaps his head around to see Baymax stuck in the window.

"Oh no." the robot said worriedly.

"Will you be quiet!" Hiro warned in a whisper.

"Yes but excuse me as I let out some air." Baymax replied and then began releasing air, sounding like a balloon deflating as he became skinner.

The shaggy hair teen rolled his eyes as this seemed to take forever. "Ok are you done?"

With one last air release Baymax replied. "Yes." Hiro walked over to the deflated robot and pulled him through the window.

"It will now take me a moment to re inflate myself." Baymax mentioned and began filling back up with air.

"Ok just keep it down." the young teen said cautiously and started down the stairs.

When Hiro made it down he began scanning around. It was dark so he couldn't really see much. Until something caught the young teen's eye, a curtain. Hiro began walking to it but abruptly stopped half way. Behind the curtain he could see a shadow moving.

A rising panic began to surge through his body. 'Oh no! Someone's here!' Hiro started backing up until he felt himself kick something. Curiosity took over the fourteen year old when he bent down to pick it up. To his surprise it was a broom. 'Well it's not my first choice of a weapon...but hey, at least it's something.'

Hiro held the broom defensively as he made his way to the curtain, his heart was beating hard against his chest. Whatever is behind there must have something to do with his microbot acting up. So with a surge of courage the young teen jumps behind the curtain.

"What the?" Hiro lowers his 'weapon' and confusion washes over his face to what he sees.

Behind the curtain was a couple of robotic arms building something and placing it on top of a rolling treadmill.

Hiro picks up the object on the treadmill and inspects it. "Its my microbots?" his eyes followed the treadmill and Hiro saw his microbots being all dumped into a blue container. The young teen walks over to the container and it was filled with microbots.

"How is this possible? They were all destroyed in the fire." he said in disbelief. 'Someone is making more.' Looking up Hiro's eyes went wide to see this wasn't the only container, but There were rows and rows of blue containers throughout the warehouse. 'A lot more..'

"Hiro."

The shaggy hair teen screamed and jumped back at the surprised call of his name. He glanced up to see no other but Baymax in front of him. "You gave me a heart attack!"

The robot began rubbing his hands together. "My hands are equipped with defibrillators. Clear."

"S-stop! Stop!" Hiro yelled frantically waving his hands in front of himself. "Its just an expression." The young teen then took a deep breath to calm himself. "Ok we have to focus." He began walking toward the containers. "Someone stole my microbots and is making more. We have to find out-"

Without warning something crashed into the ground with incredible force, slid backwards and smashed through multiple containers spilling them over.

"W-what was that?" Hiro asked.

"A human." Baymax responded.

"Huh?" the shaggy hair teen uttered, looking up at the robot.

"My sensors scan a human, male, 16 years of age, five feet and seven inches,-"

"Yeah I get it the idea, but where?" Hiro asked cutting off Baymax.

The white robot pointed to the giant pile of spilled microbots. "There."

The shaggy hair teen gave him a puzzled look. It was surprising to think it was a person that shot to the ground like that. "Um...are you sure Baymax?"

"Yes." The robot answers. "That is what my scanner reads."

"Well ok." Hiro nodded. "Guess I better check it out." He said and slowly started making his way to the pile. 'Whoever is in there has to have something to do with what's going on.' Considering if that person is even alive, that fall was deadly. The only way Hiro could see this person surviving is by having all their bones broken. The young teen shook his head of all the horrid thoughts of what this person was going to look like.

When Hiro approached the pile of microbots he was visually shaking. 'Don't chicken out now Hiro!' he told himself. With a nervous gulp he slowly started reaching his hand out to the pile.

But before he could even touch it, some guy shot forward. "Aw man!" he groaned. Hiro stood back in shock as the guy rose up to his feet. "That kinda hurt.." he said rubbing the back of his head.

The guy looked around Hiro's age, maybe a year or two older at the most, but was way taller than him. He had bright orange hair with black tips at the end that was a little past his shoulders, and was tied back into a braid. He wore a black cloak that was tied around his neck and looked like a cape. Underneath was a white long sleeve shirt with black arm brackets around his wrists. The guy had white loose fitted pants that was above his ankles with a red flame design at the bottom and a red sash was tied over his waste. Lastly he had black Chinese style shoes.

To Hiro the guy looked like a mountain man who's never seen civilization before. But the real question was how was he alive? A fall like that would have killed a person or survived with every bone in their body shattered. And here this guy was looking like he had just fell off a bike.

The orange haired guy then glanced over to Hiro, blinking in confusion with his bright green eyes and cocking an eyebrow. "Who the heck are you?"

Hiro blinked. "I'm...I mean, I should be asking you that!" he stated in a more stern tone trying to sound more fierce. "Why are you here with my microbots."

The guy stared blankly at him. "Microbots? Wazz that?"

"The stuff all around you." the young teen answered crossing his arms.

The orange haired teen looked down. "Ohh...wait? These things are yours?"

"Yes! And no...well they're my invention.." Hiro says in an unsure way. "Nevermind! The point is why are you here? Did you steal my microbots?"

"Kid I didn't steal nuthin." the guy scoffed. "And the reason I'm here is none of your business. I also suggest that you leave this place right now."

Hiro frowned. "leave? I'm not going anywhere until I-" the young teen stopped as the ground suddenly began shaking making him stumble a bit. "W-what's going on?"

The microbot Hiro had in the bowl started shaking harder. Then suddenly all the microbots began rising from the containers and bundling together. The shaggy hair teen watched with wide terrified eyes as the microbots grew higher like a giant wave. The orange haired guy shifted himself as if he was getting ready to do something.

Then from above on top of another staircase a man appears from the shadows. He was in a black suit that showed none of his skin, dark gloves over his hands, and on his face was a white and red kabuki mask.

"Hey kid." The orange haired teen called. "I think now would be a good time for you to dip."

And with a flick of his hand, the guy with the mask shot the microbots down at them. Hiro quickly sprinted off and the orange haired teen leapt sideways as the robot wave smashed into where they were standing.

The guy didn't have to tell Hiro a third time to run, he knew this situation was out of his control.

"Baymax come on!" the young teen yelled when he ran past the soft robot. When he realized Baymax wasn't right behind him, he skidded to a halt and turned back to him.

The squishy robot was waddling very slowly over to him. Before Hiro could say anything his eyes went upward when he caught sight of the orange haired teen. His jaw nearly dropped.

The guy shot upwards with an incredible jump landing on a rail then sprung off it with another amazing jump. The shaggy hair teen has never in his life witnessed a human who could jump that high.

"Why don't ya give it back before you piss me off!" He barked charging toward the masked man.

'Give what back?' Hiro thought. He couldn't help but wonder what was taken from the orange haired teen, but he didn't really have time for that. The young teen's eyes shot back the Baymax. The robot was still traveling at his own very slow pace, not getting any closer to him. "Baymax hurry!" Hiro snapped desperately.

"I am not fast." the soft robot simply replied.

The young teen ran to Baymax at full speed, grabbed his hand, and charged forward. "Yeah no kidding!"

Hiro ran to the locked door thinking it would be the quickest get away. "Baymax kick it down!" he exclaimed. The white robot blinked at him then turned to the door and lightly kicked it, which had no effect to the door. "Punch it!" Hiro commanded. Baymax did as told and raised his fist up and hit the door, once again no damage was inflicted.

The young teen groaned in irritation and turned back around to see what was happening. He saw the orange haired teen charging up toward the mask guy. The mysterious man reacted quickly and sent more microbots at him.

Hiro was about to yell out to the orange haired teen, but there was no need when he shot sideways, letting the wave hit the ground.

The orange haired teen landed on another rail. "Alright man that was your last chance to give it back nicely." he then vaulted off the rail with a new powerful jump, once again heading toward the mask guy.

The mysterious man didn't hesitate to send another wave of microbots to him, but the orange haired teen twisted around it with inhumanly agility skills.

'This would be so awesome If we weren't in danger right now.' Hiro thought gaping in shock. It didn't take long until the mask man caught sight of the shaggy hair teen and squishy robot and sent another hoard of microbots at them.

"Oh no!" Hiro cried in alarm. He quickly grabbed Baymax and shoved him through a short thin hallway. "Go! Go! Go!"

When they reached the end Hiro saw the staircase they came down from. "There! That's our way-" The young teen paused, his eyes went wide with shock as he came to a sudden halt as something started rising out of the ground, blocking his and Baymax's path to the staircase.

When it was fully out the ground Hiro's brown eyes quivered in horror to what he saw. It had the shape of a human but was black like a shadow. It had no eyes but a giant mouth with huge teeth. And the creature breathed heavily, like a predator about to attack it's prey. Hiro's blood ran cold as the creature began moving toward them.

"B-baymax what is that?" he asked trembling and stepping back.

"I don't not know, my scanner is not able to identify it." the white robot replied.

"Well then we better run!" Hiro yelled grabbing Baymax and darting off into a different direction. But before they could get far another creature appeared in front of them. Hiro skidded to a stop and quickly ran in another direction. "This way!" Then more creatures started popping up all around them, and they became completely surrounded.

"Gotcha now!" the orange haired teen yelled. He was now above the mask man and was about to dive on him.

Before the orange haired teen could clear the distance the mysterious man launched two giant waves of microbots at him.

"Damn these dumb robots are getting on my nerves!" the orange haired teen pulled back his fist. "Tornado fist!"

At that moment a rushing tornado fired out of the teen's fist, instantly ripping through the hoard of microbots. The mask man stood there in shock.

"You're going down man!" the orange haired teen shouted shooting toward the shady man. The mask man quickly shoved his hand into his coat and pulled out a necklace. The teen's eyes widen. "My necklace!"

The mask man turned around, pulled back his arm, and threw the necklace away.

"Crap!" the orange haired teen cursed and landed on the rail in front of the mask man then shooting right past him to go after the necklace.

The orange haired teen quickly caught it in the air. "Ha got it!"

"Fool." the mask man spat.

A second later three of the creatures that appeared in front of Hiro and Baymax rushed at the orange haired teen.

"Aw great.." the teen sighed in irritation. 'Shouldn't had let my guard down.' The orange haired teen quickly ducked as a claw slipped past his cheek and slammed his fist into the creature's midsection, making the monster suddenly disappeared into dust.

The orange haired teen barely had time to blink when another one threw itself at him and pierced it's sharp fangs into his skin. The teen merely winced and slammed his foot down on it's head making the creature disappear as well.

Before the third one could attack the orange haired teen caught it between his feet. He also noticed that he was getting closer to the ground, so the teen pulled the creature under him. When they came into contact with the ground the creature made a loud screech as it was smashed against the hard floor and instantly disappearing.

The orange haired teen dusted himself off, shoved the necklace into his pocket, then looked up to the mask man. "Thought ya had me there huh." he then smirked and cracked his knuckles. "Round two man. And now that I got my necklace back, there won't be any distractions."

The mysterious man did a dark chuckle. "Are you sure about that."

Before the teen could respond there was a loud scream throughout the warehouse. The orange haired teen's eyes widen in alarm. "Oh crap, that kid!" he quickly rushed over to the cry without a second thought.

"L-let go of me!" Hiro yelled. Two of the creatures had each of his arms pinned down while one was on top of him.

"I am sorry I can not be any help to you Hiro." Baymax apologized. He also was being pinned down by several monsters not able to move.

The creature on top of Hiro placed it's claws on his face, they were ice cold and gave him goose bumps. The monster then opened it's mouth and began to move closer to Hiro's face. The shaggy hair teen screwed his eyes shut. Was this it? Was he going to die right here...

Without warning, the creature was ripped off him. Hiro opened his eyes to see the orange haired teen tossing the creature away like a rag doll then watching it disappear into dust when it hit the floor. The orange haired teen then smashed his foot into one of the creatures holding Hiro's arm, then spun around to slam his fist into the other monster's face, making both disappear into dust.

"Whoa.." Hiro sat up and stared at him in amazement. "That was so- Hey!" the shaggy hair teen yelped as the orange haired teen grabbed him and threw him over his shoulder.

"Save the talk for later kid." He said quickly. The orange haired teen then dashed over to Baymax.

The creatures leapt off the white robot and launched themselves at them. The orange haired teen's fist blurred into a frenzy of fast powerful punches all connecting with his targets, only leaving a cloud of dust.

"How did you do that?" Hiro asked lifting his head up.

"I told you to save the chit chat for later." the teen replied and snatched Baymax's hand. "We gotta go." the orange haired teen sprinted up the stairs and charged to the window.

"Whoa! Slow down, you're gonna run through the window!" Hiro warned.

"Thats kinda the point genius." the teen replied as if it was obvious.

"Say what!" Hiro panicked. "Are you crazy!"

"A fall from this height can lead to serious injury." Baymax added.

"Well you got any better ideas? Cuz we don't really have time to stop and think with our little friend on our tail." the orange haired teen shot back.

"What!" the shaggy hair teen lifted his head up to see the mask man riding on a wave of microbots not too far behind them.

"You won't escape!" he threatened firing the tiny robots down at them.

"Put your head down kid!" the orange haired teen ordered.

The next thing that happened was them smashing straight through the window that Hiro and Baymax first came out of, as the wave of microbots crashed into the ground. Glass flew everywhere as they sailed out into open air.

Hiro held his head down while the orange haired teen's face was contorted in a determined deep set glare, his braid flapping behind him as the wind rushed past his face, whipping the bangs of his hair against his face.

It felt as if time slowed down and they were floating, like a leaf on the wind. Then time went back to normal when the orange haired teen landed on the the ground straight on his feet, while Baymax landed directly on his face.

The orange haired teen didn't stop to check if the robot or Hiro was okay, he just tightened his grip on both of them and sprinted off.
