The kabuki mask flew off and clattered to the floor. Hiro hesitantly straightened up, this was it. Now what?

"It's over, Krei." his voice quavered. The man in the trench coat slowly turned, and the young boy's eyes widened. This wasn't Alistair Krei. This man had a broader jaw line, a larger nose and a more prominent, protruding brow.

"Professor Callaghan?" Hiro whispered, voice small and vulnerable. From the higher level, his four friends were silent, quietly mouthing their disbelief.

Now that he thought back, Hiro wondered how he ever suspected Krei. This stranger obviously had a wider build, and was shorter in stature. Of course, he'd had his suspicions, but, he couldn't bring himself to believe that the man his brother had looked up to and spoken of so highly, was the one responsible for Tadashi's death.

"Give me the mask, Hiro." Callaghan's tone was dangerously low, but Hiro payed no attention.

"You died." he whimpered. "You died!" his breaths were becoming quick and shallow, mind whirling.

"No, I had your microbots." the professor explained. It didn't make any sense. Why would Callaghan do this?

"But, Tadashi." Hiro protested. "He went in there to save you!" the young Hamada felt his words choke as his throat swelled.

"That was his mistake!" as he said this, Tadashi's creation, Baymax entered, sporting bright red armour.

Hiro once again felt the heavy, dull pain thud in his chest. Tadashi's sacrifice had all been in vain. Because of a man he trusted. A man they had all trusted.
But not anymore.

"Baymax, destroy." the order left his lips without regret. His brother, the one person he had left, was gone. His absence left a hole in his heart, in his whole being, that nothing could fill ever again. Because sometimes, what you need isn't a mother's hug, or a father's caring words, or even your Aunt, whom you love ever so much's, cooking. It's an older brother who chases away the bullies, and the dark, and everything a fourteen year old could possibly worry about.

"My programming prevents me from harming a human being." Baymax protested.

Hiro clenched his fists. What he was about to do, Tadashi would never do, nor would he ever want to.

But he wasn't Tadashi.

Tadashi was gone.

"Not anymore."

What came next was a blur. He felt, but he couldn't see. No he did see, but only red, a bright angry shade of red. Like the colour of an open wound. He felt his fingers closing around a small chip. Then the sound of plastic crunching beneath his boot.

"Destroy."

Then he saw different colours.

A streak of yellow, bursts of pink, dots of green and blue.

"Don't do it Baymax!" voices, so many of them. Overwhelming him, yelling different things. Then faces, the faces of his friends, contorted in pain.

Then he saw a different shade of red. A darker red. A sticky, warm liquid running down his hands and face. He closes his eyes with the realisation of what he's done. And then for a second, everything is silent. Heavy breathing and pants, his thudding heartbeat, the ringing in his ears. He doesn't dare open his eyes, in fear of what he'll see next. But the crash of concrete forces him to face the consequences of his actions.

He sees a black trench coat. A cracked mask.

And red.

Red everywhere.

"Hiro, what did you do?" a voice whispered. Honey Lemon. Hiro turned to look at his friends. They all wore expressions of anger, horror, but mostly, fear.

"I- I'm sorry. I didn't-"

"What you just did, we never signed up for." the usually gentle Wasabi growled. Hiro hung his head, the severity of what he did washing over him.

"I'm just as bad as Callaghan, aren't I?" he sobbed. Honey Lemon's eyes softened ever so slightly.

"No, Hiro." she soothed him, well knowing how unconvincing she sounded. Suddenly, a heavy blow to his neck caused him to fly across the room, head knocking onto the unforgiving concrete floor. Eyes sticky with blood and tears, he struggled to open his eyes, gasping as he realised who had dealt the blow. None other than Baymax. The supposedly kind, huggable nurse bot. "Baymax, stop!" Hiro protested, backing up. He urgently scanned the room for Baymax's original chip, before realising, he destroyed it.

"Destroy." the robot simply replied, mimicking Hiro's earlier command, nearing closer and closer to his creator's brother. A flash of golden armour stopped between Hiro and Baymax.

"Get back." Gogo warned the younger boy. Hiro spent no time protesting, scrambling as far as possible from the robot. The three other armoured heroes placed themselves between the robot and their friend, willing to protect him at all costs. He may have done a horrible thing, but they were willing to give up their lives. For Tadashi. They owed him that much. Hiro watched in horror as his friends (could he even be called their friend anymore?), already beaten and bruised were knocked aside and beaten down. The sound of bones crunching and cries of agony and torment filled the room. Bodies were thrown around, and collapsed to the floor, limp as rag dolls. But despite this, Hiro could still see the hesitation in their eyes. None of them were quite willing to destroy the robot, regardless of the pain he was inflicting on them. This was their last memory of Tadashi. The last memory they had of their best friend.

But Hiro knew better. Destroying Baymax now wouldn't make a difference. Baymax had died under Hiro's boot. He had been the one to kill Tadashi's memory.

He really was just as bad as Callaghan.

Another punch was delivered to his chest, the sound of ribs cracking echoed in his ears. Hiro groaned, sliding down against the wall. He made eye contact with one of his teammates. Fred. His dragon mask had long since been knocked off. The mascot's blonde hair stuck to his forehead and eyes, sticky with sweat and blood, and his ankle was bent at an awkward angle. The two shared a moment of silent communication. They both knew what was coming. Fred gave one last nod, saluting before heroically charging the destructive robot.

"I'm sorry." Hiro whispered, his voice too hoarse to form words. The thudding in his head got louder and harder. His breaths were getting shorter and raspier, blocked by the clots of dried blood in his throat.

Thump. Thump. Thump.

He could physically feel his heartbeat slowing, getting weaker and weaker. A quiet groan made the notorious droid aware of his presence. His friends couldn't save him now.

Are you waiting for me Tadashi?

I'll be there soon.

I didn't get a lot of reviews for the last chapter, what did you think?
