A/N: Not sure if Hidashi or Hidashi yet... You know what you guys choose and let me know which you prefer (brotherly love or incest), I don't care either way for this story.

I'm not a very good story writer so expect loooong updates or even...NO NEW CHAPTERS...soz.

Chapter 1

He Who Is My Superman

This was the moment that he'd been waiting for! Hiro glared up ahead as he trailed down the hallway with Baymax closely behind. The other four were clumped together with Fred being ever the noisy one as he attempted to name their group, speaking loudly to himself.

"The Big Enchiladas! No..that makes me hungry. How about the 6 Amigos? No. No... Ooh! Fred's Angels! I dig that one! We're going to be Fred's Angels!" The young beanie capped man exclaimed, giving himself a mental pat on the back.

"Oh shut it, Fred." GoGo, the short Korean girl growled from next to him, popping some gum in her mouth as she elbowed him in the ribs. "You need to stop being a dorky man and woman up sometimes!"

"Sshh! Yokai might hear us!" The biggest of the group, a buff dark-skinned man named Wasabi whimpered and hid behind the lanky brunette. The image alone was a huge contrast.

Hiro ignored the older teens and kept his head forward. They didn't matter. They were just a means to an end. When he unmasks Krei, he'll...finally get justice for his brother's death.

Justice.

The thought alone broke him out of his daydream and he unclenched fists he hadn't realized he had clenched. Just as he unfurled his fists, he felt something else constrict in their place.

A small ache echoed in his heart and he wasn't sure why.

–

Hiro felt like slapping himself in the face as everyone attacked Yokai in horrible uncoordinated fashion. Fred was thrown aside right as he jumped at the villain with a flick of the wrist. Wasabi kept cowering behind the support beams, trying to sneak up on the man but was being too obvious. And the girls were no better with Honey Lemon mixing her chemicals to make a glue-like substance and missed her throw ending up hitting GoGo instead.

"Focus on taking the mask off!" Hiro ordered his comrades.

GoGo was the first to get herself together as she used her spinning magnetic wheels as a makeshift chainsaw, cutting through Honey Lemon's chemical compound through a combination of intense heat and sharp blades before jumping at Yokai. He narrowly dodged her, in what seemed to be a look of surprise but it was hard to tell from the mask covering his face. While he sent his microbots against her, Honey Lemon threw another compound at him, getting his attention as he tried to rip away and send another swarm towards the other girl. Wasabi came running and slammed his energy blades into the ground, cutting out the cement before he kicked it at the microbots and lunged at Honey, pulling her to safety. Before Yokai could retaliate, GoGo came from behind and kicked him in the back of his knees, causing him to trip.

Yokai growled menacingly before engulfing the tomboy in a pool of microbots, leaving only her head sticking out. He raised a hand and made a motion to crush her but then Fred appeared out of nowhere doing a handstand and shooting flames straight at him, causing him to cover his face in his arms in an attempt to block them.

Hiro and Baymax finished Yokai as they flew at him, knocking him to the ground with the mask flying off in the distance. Once the mask came flying off, he immediately covered his face with a hand, his hair frazzled and in disarray in front of his face.

"Give it up, Krei! We already know–" Hiro jumped off of Baymax and froze as he got a closer look at the man in front of him.

A somewhat familiar looking face looked back at him with eyes filled with hate and disgust through dark bangs. Half of his face was red with stretched skin, disfigured almost beyond recognition from a fire; likely the same fire that was started at the convention. And what was left of his skin was a light brown tone, almost porcelain in color but not quite.

As Hiro looked over the figure more and more he began to realize something that his brain had already registered...

This man was not Alistair Krei!

If there were a few things that Hiro knew about Alistair Krei, it was that he was still in one piece. His face wasn't disfigured from any heat source of any kind and his hair was a dark blond like Honey Lemon's, not pitch black.

He began to hyperventilate. Who was this man with such a familiar looking face? Why did his heart ache as he gazed at him? Why did he steal his microbots and attempt to kill him and his companions?

Just who was he?!

"Tadashi is here." Baymax suddenly beeped in his mechanical voice as he came up slowly from behind Hiro, placing a tender hand over the boy's shoulders.

"What are you talking about?" Hiro asked with a scoff, stupefied. "He died in the fire you stupid bot!" The young fourteen year old felt the urge to raise his hand and smack Baymax even though it would be pointless. How dare Baymax mention Tadashi and at a time like this?

"My scans are showing my creator, Tadashi Hamada, standing exactly 5 meters in front of us." Baymax said and looked at the man covering his face who was baring his fangs at them, "Tadashi, you are showing signs of heavy third degree burns on contortions of your face and a mix of third and second degree burns around your upper right torso and lower back along with some strange mechanical augmentations. I recommend immediate care with deep surgery and skin grafts followed by months of hospitalization."

The robotic man's voice flew over Hiro as a horrible realization hit him.

Could it be? "T-Tadashi? Is that really you?" How could he forget his own brother's face? Even with his physical change, Hiro should have noticed that it was Tadashi! All of the emotions that he had bottled began to diffuse and leave him until he was left with a hollow void inside. The young genius fell to his knees and looked up at the man who continued to glare at him with those unfamiliar eyes making him gulp. Eyes that he had never seen before with such hate and disdain from someone so close to him.

Why was Tadashi looking at him like that! He felt his heart squeeze until it collapsed on itself, breaking ten times over but the emptiness inside it was an even worst pain.

"Tadashi?!" The others grouped around Hiro, trying to pull the poor boy out of his condition. They huddled protectively around him, a few of them glancing up to look at their long thought dead friend. Everyone stayed there cautiously, unsure of what to do next.

This is Tadashi Hamada...

No, that man, whoever that man was, had tried to kill them multiple times earlier. Could he be the very same Tadashi that they had once called a friend? The one who pushed himself to his limits of every waking day and every sleepless night to create a world where the sick and helpless were always cared for? The Tadashi that idealistically (perhaps even foolishly) believed in a world without fighting and painful suffering? Was this that very same friend?

If so, why was he going so much out of his way to harm them...even kill them?

Hiro crawled closer to his older brother, looking up at him with big wet eyes. "Hiro!" The others tried to call out to him, worriedly but the boy ignored them. All he could think about was Tadashi. Nothing else existed at the moment, just the two of them.

"Why didn't you come back after all this time? Where were you?!" He was now kneeling at Tadashi's feet with tears raining down from his eyes.

Tadashi looked at his younger brother with a somewhat passive gaze from through his fingertips, baring his teeth slightly like a mad dog and something clicked and Baymax's passive eyes began to blink rapidly, quickly scanning his surroundings.

"Hiro, move away now!" The robot panicked in a slightly monotonous tone. "Tadashi's stress levels are increasing exponentially and he may start to behave in an irrational manner."

Hiro and the others didn't seem to register the robot's warnings as a horde of microbots appeared from three different directions above Hiro and came plummeting down like a torrent of heavy metal. Luckily for Hiro, Baymax was able to think fast on his feet and rocket boosted under him just before the bots crushed him under their combined weight and power, though Baymax's rockets were damaged instead.

"T-Tadashi!" Hiro choked out in surprise. 'How's he controlling the microbots without the mask?'

"You don't understand." Tadashi finally spoke up, his voice coarse from disuse. He let go of his face and stood upright to glare at his past friends and brother. He raised his right hand in the air, gathering all of the microbots as they formed upwards into a giant spinning spiral.

"Should we like stop him or something?" Fred cried as he hung onto the ground with the claws of his lizard costume for dear life. "I think I'm gonna fly away!" Just as he said this, he did just that as the turbulence of the spiraling bots sent him packing. His cries of 'THIS IS TOTALLY AWESOME!' echoed as he disappeared into the distance.

"Everyone quick!" Honey Lemon said as she threw three of her chemical pellets onto the ground and created a giant wall that was glued between two of the support beams. GoGo and Wasabi both dived behind it alongside the blonde girl. All of them were huddled together with closed eyes preparing for the worst just as the massive wind had begun to die down.

Wasabi blinked and was the first one to duck his head over to the side of the shield to see a giant hole in the roof of the building with a low orange light shooting down from it but there were no signs of Tadashi or his microbots.

"Ugh, guys?" Wasabi called out to the rest of his friends. Each girl began to stand up with him as they took in the new view. When he turned around Fred popped out of the ground in front of him like a mole, scaring the living bejeezus out of him and Wasabi screamed like a little girl.

"Yo, what'd I miss?" Fred asks as he shook cement rubble off of his head.

"Wait–Didn't you fly–I mean–How?–Fred?!–Outta the ground?" Wasabi blubbered on but shut his mouth and smacked himself in the forehead.

He decided he didn't want to know.

Honey Lemon looked around nervously before she finally spotted Hiro in the distance with Baymax hugging him in a protective embrace. She hurriedly jogged towards him, worry etched on her face.

"Hiro!" She called.

Hiro just kept staring out into the distance at where Tadashi once stood. His pupils faded black as if he was dead to the world and his breathing became shallow.

"Hiro! Are you alright?" Honey Lemon said and grabbed him by the shoulders, giving him a light shake that quickly turned into heavy shakes. Honey's broken cries brought everyone else's attention and they all grouped around the young genius who was still stuck in his daze.

Everyone began to grow more worried over the Hiro as time passed. Each of them looked at him with a sense of despair and hopelessness.

"Kid," GoGo slapped him in the back, "Hey, kid! Wake up!" She chewed on her lower lips, wrapping an arm over her chest. She's never dealt with kids before and was at a lost for words, not to mention she could barely understand what was going through his mind.

"Hiro is in shock." Baymax voiced out loud. They all looked up, surprised, completely forgetting the huggable robot was even there. "He is currently in a state of confusion and needs fresh air and some bed rest." The robot added. "Unfortunately, my jet rockets are in need of repair and I cannot take any of us back to the city." He gestured towards his boots and the teens saw that they were in complete shambles.

"Oh, that's a bummer, dude." Fred gave his sympathies to the robot. Then he pulled out his cell-phone. "Hey, Heathcliff, do ya think you can pick us up? It's no problem? Alright, that's awesome! You're the best." Just as he put his phone down he looked up to see all of his friends, minus Hiro and Baymax, staring at him with wide eyes and open mouths.

"What?" Fred says, looking very confused at their expressions.

"Your butler is going to pick us up? On a remote abandoned island?" They all asked in unison.

"Sure!" He replies as if it was normal.

They all wondered how the butler was going to get them in the middle of nowhere island.

–

Who knew that Fred had a private helicopter? The young man never stopped amazing his friends.

"I. HATE. FLYING!" Wasabi complained as he clung onto Baymax's arm, squeezing himself into a tight ball.

"What a scaredy cat, it's not like you've never flown before." GoGo says, rolling her eyes. She was slouched over from the opposite side of him from next to Honey Lemon who could only give Wasabi a small look of sympathy and understanding.

"The first time I've ever flew was like an hour ago!" Wasabi complained, giving her a slight glare. He raised his feet over the seat and into Baymax's lap.

While the four friends were busy chatting away, all trying to forget the events prior that night, Baymax turned to his left to look at Hiro who was still in a daze.

"Is everything alright, Hiro?" He asks.

After what seemed like forever, Hiro was finally brought out of his shock. "Ugh, yeah. I'm fine...Baymax." He replies softly, sighing loudly. His demeanor was weak and broken.

"My scans show your heart rate increasing and breathing becoming uncontrollable. It seems you are about to go into another panic attack." The large robot stated.

"N-No, I'm fine Baymax. It's just–What happened to Tadashi?" He asks and suddenly everything became quiet. Everyone looked back nervously at each other, afraid of what was going through the young child's mind. "I mean–Don't get me wrong! Tadashi's alive and that's all I can ask for...and I'm thankful for that. I just want to know why!" His eyes began to tear up again. "Why? Why?!" He repeated, looking ready to fall apart again before Baymax bent down and hugged him, saying 'There there'.

That was the same question going through everyone else's mind, too. They all thought they knew who Tadashi Hamada was but none of this seemed to fit!

Why did he try to kill them? Why did he never try to contact any of them? Why was he doing all of this?

They were afraid of never getting an answer...or gulp even worse, actually getting an answer.

"Like you said, kid," GoGo finally spoke up, worry was in her eyes. She turned her head away from him, casting him a side glance before getting the courage to face him properly and smiled weakly. "Tadashi is alive! We can ignore the rest of the details for now. Maybe some crap happened to him or he's going through something but that's where you come in!" She said, somewhat not actually believing her own words. She gave him a punch in the shoulder which made Hiro shout out in pain. "We'll get Tadashi back. That's a promise!" This time she smiled for real. Maybe if she kept lying to herself everything really will turn out for the better?

"You said it GoGo!" The others butted in. "I'm there with you!" Fred said. "We'll just bring Tadashi back to his senses." Wasabi nodded. "Tadashi is our friend, we just have to show him the way!" Honey cheered, bumping her fist in the air excitedly.

Looking at everyone as they cheered him on brought a small smile to Hiro's face. He could see why they were one of Tadashi's favorite people. They really were a good group.

"Yeah..." He starts, slightly rubbing at his shoulder where GoGo had punched him earlier, "We'll get my big brother back." He gave a toothy grin, thinking maybe–No! It really will be alright! 'I'll never give up on you...' Memories of the past rang out in his head from a soft caring whisper as a figure held him tightly in a warm embrace. "I'll never give up on you," Hiro repeated aloud with absolution.

He ignored the pang that went through his head.

–

Standing atop one of the larger trees, a dark figure cloaked in a black jacket was watching them pass overhead. He growled and clenched his fists tightly at his sides, watching them with the utmost disdain.

A spiral of black trailed up slowly around his tree, creating the sounds of thrashing bark and chirping cicadas. The swarm of miniscule robots buzzed and hovered menacingly in front of him before they parted away and revealed a mask of white and red spirals: a Kabuki mask.

He slowly reached forward, grabbing it and putting it on over his scorched face. He looked back up and stared at the horizon, his hazel eyes burning an intense orange from through the eye-hole as it reflected the light coming off of the flaming ball of fury that was breaking in a new day.

Things were never going to be back to the way they were before.
