Chapter 1: A Hero's Night

It was nighttime in the city of San Fransokyo, with the city skyline illuminated by in sparkling lights like the night sky. In the outskirts of San Fransokyo was the San Fransokyo Institute of Technology, a university where the best boys and best girls of all backgrounds come together to learn and work on various scientific progresses, from advanced robotics to chemistry and physics. Currently, five students and a giant robot occupied the main lab of the Institute, nicknamed the "Nerd Lab". 15 year old Hiro Hamada, GoGo Tomago, Wasabi Ginger, Honey Lemon, Fred and Baymax were each standing in their own Plexiglas box, with tiny airholes at the top. Their only connection was a microphone system that Hiro connected to each case.

"All right guys," Hiro said into his microphone, "This is test number one for our Morpher Watches."

"Morpher Watches," Fred said, "I thought I was supposed to come up with the cool names."

"It's a work-in-progress," Hiro said with a chuckle, "If these work, I'll let you come up with the name."

"Uh, remind me why you have us in Plexiglas cages?" Wasabi asked nervously.

"Our watches are supposed to release tiny nanobots onto our skin," Hiro said, "Which would head for our respective body parts and form our costumes."

"That's not what he was asking," GoGo said irritated. Hiro bit his lip.

"The only problem is that these nanobots are known to be a bit volatile," he said nervously, "So if my calculations are off, there's a slight possibly of an explosion."

"Explosion?" Honey Lemon repeated nervously, "As in…?"

"Yes, Miss Lemon," Baymax said, "Explosion is a common term for a sudden expansion of energy, commonly associated with disintegration and-"

"I know what an explosion is," Honey Lemon interrupted, still feeling nervous.

"Well, this is filling me with confidence," Wasabi said sarcastically.

"Relax," Hiro said, "The chances are small. Still, better safe than sorry. Anyway, Fred, could you give us a countdown for our first test run?" Fred just smiled, ready to face the danger.

"Glad to," he said as he prepped himself with a finger on his watch, "Alright everyone, Hero Watch test one (which I think is a better name) in three…two…one…GO HERO!" As soon as he yelled that last part, everyone pressed their Hero Watches.

Hiro felt a strange ticklish feeling as the millions of nanobots swarmed over his skin, but as quickly as he felt it, the feeling was gone, and he found himself in his full costume. Everyone was in his or her suits, forming the super hero team Big Hero 6. Baymax was also surprisingly in his armor.

"Wow," Honey Lemon said, "That felt strange."

"Did I forget to mention that I'm ticklish?" Wasabi said as he rubbed his suit. He then widened his eyes at Baymax.

"Wait, how did he get into his suit?" he said, "He's not wearing a watch."

"His suit's connected to my watch," Hiro said, "We change at the same time."

"That was awesome!" Fred cheered as he admired himself in his bulky, fire lizard suit. GoGo wasn't really impressed, as something else was on her mind.

"Go Hero?" she asked Fred with a raised eyebrow.

"Oh come on! I thought it would be a cool catchphrase! You know, up, up and away?" GoGo just sighed and shook her head in annoyance.

"Alright," Hiro said, "Now we just need to check our suits' functionality, so I figured we could go outside and-" They suddenly heard a series of rapid beeps and turned to Baymax. Hiro upgraded Baymax with a mock satellite system so that they can pick up radio messages from the police or other emergency services. Right now, Baymax's belly glowed with a green screen with a light green line jagging up and down with the radio feed.

"All units, we have a reported 10-80 coming from the intersection of Miyazaki and Toho. Unidentified number of civilians trapped. Report in."

The radio feed terminated and Baymax's belly went dark.

"Or we could just respond to this thing." Hiro said with a shrug. With that, the team rushed outside and got themselves onto Baymax to fly to the situation. Honey Lemon and GoGo sat with Hiro on Baymax's back, while Fred and Wasabi each hung on Baymax's arm.

"You realize I'm still terrified of heights right?" Wasabi said worryingly as they flew over the city. After a small period of flying they were closing in on Mayazaki and Toho.

"Um, what's a 10-80 again?" Honey Lemon asked politely. Hiro thought about it for a while, since he never really had the entire emergency code programming memorized even after a year of crime fighting.

"I think 10-80 is supposed to be an explosion," Hiro said, "Which probably means-" He didn't have to finish it, because they reached their destination and saw what the problem was.

An apartment building was on fire, causing Hiro to widen his eyes in fear. Baymax was already at work, as seconds later, he reported that:

"I've detected six life signs inside, 2 on the 22nd floor and 3 on the 20th."

"Right," Hiro said worried, "Honey Lemon and Wasabi will take the 22nd floor. Fred and GoGo, the 20th. Meet up at the 21st when that's everyone for extraction." Once everyone got his or her orders, Baymax flew close to the building where the team got inside their respective floors. Once the team were inside, Hiro and Baymax flew back to survey the rescue efforts.

"Baymax, keep a close eye on the team, track their signatures," Hiro said.

"Scanning for team," Baymax replied. After a few minutes of tense silence, Hiro finally heard Honey Lemon on his headset.

"Okay, that's all of them," Honey said with a few coughs, "Now, how's extraction going to work?"

"Just head to the southern windows," Hiro said," We'll have a wing ready for you to climb on." With that, Baymax flew closer to the building, causing Hiro to cringe. He could feel the flames licking his suit, and he could almost see Tadashi in the flames.

Come on Hiro! He thought to himself. You can do this! They won't end up like Tadashi!

Suddenly he heard a crash on his headset. A piece of the building must have fallen down.

"Hiro! We're blocked!" GoGo said, "We need you in here!" Hiro panicked. His team was stuck in the building, and he needed to go inside the burning building, one that could collapse and explode at any minute. He didn't know what to do, and he couldn't come up with what to say. The other team members kept calling out to him, but fear gripped him tightly, squeezing out any kind of words.

Then the building collapsed, the fiery structure suddenly turned to pure ash. Hiro gaped at this, shock and dread filling his entire body.

"Baymax! Scan for them!" Hiro said fearfully, "Guys? Guys? Can you read me?" He only got static.

"The team is there," Baymax said, pointing at a nearby building. To Hiro's relief, Baymax was right. The team was panting on the rooftop of the next door building, covered with soot. By there side were the civilians that were trapped in the fire, coughing and panting.

"Guys!" Hiro said relieved, "Are you okay?" GoGo just glared at Hiro.

"What was that?" she said frustrated, "You just went quiet all of a sudden."

"I..uh…" Hiro tried to give an excuse, but was too nervous to think of anything. He finally just shook his head.

"It doesn't matter," Hiro said, "We need to get these people to a hospital!" After some concerned expressions, the team agreed and carried the civilians with them onto Baymax, as he flew them to a local hospital. Hiro could still remember Tadashi's last words.

"Someone has to help!"
