A/N: For the person that may not know it but if the sentence is italicized its a thought. Most likely Hiro's ahah so yeah...


No one knew what it was like. They tried to understand but it was impossible. He knew him longer, he had a better bond with him than anyone had. He understood him better than anyone. They understood he was hurting but nothing they could ever say could fill the void in his heart. Only one person could. He was gone. Gone… Gone because of the man before him. The man that took everything from him. Who cared about the stupid microbots? The microbots were easily replaceable. But flesh and blood was not easily replaced. Especially when its about the only family you have left. Gone because of this sorry excuse for a human being, who had not even faced in his direction yet. Hiro wanted to see the man who took his brother's life, face to face. Soon he would be face to face with the cold blood killer who made his world come crashing down.

We'll make everything right nii-chan…I promise.

"It's over Krei…" Hiro breathed staring at the man lying in front of him.

The man stirred trying to get up, he did not face the boy.

We got you now Krei it's no use running..

The man took his time getting up knowing he was defeated but refused to give up. The tension between them was heavy. The silence was broken when Yokai turned and finally face Hiro. The eerie silence was filled with gasps from all around. Hiro took a few steps back, he couldn't believe what he was seeing.

"No…No…" Hiro shook his head repeating the word as if it would change what his eyes were seeing. Tears were forming in the boy's eyes, he didn't dare let them fall. No not yet, he has the upper hand. Hiro didn't want to show weakness even though he felt it deep inside. His stomach knotted up, he felt sick.

That's…that's impossible! Professor Callaghan is the man behind the mask! It can't be him it has to be Krei!

"Give me the mask, Hiro." Callaghan demanded.

Hiro blinked back more tears, "But…but the fire…you died…"

"No, I had your microbots." Callaghan hissed.

"T-tadashi..He went in there to save you!" it hurt to talk, he felt like he was going to throw up. Hiro couldn't hold his tears back any longer. He let them flow whether he wanted to or not he didn't care. The man, his idol, his brother's idol, was a cold blooded killer. Hiro looked in Callaghan's eyes for any hint of remorse. He found none.

"That was his mistake! Now be a good kid and hand over the mask Hiro." His words like venom.

Something inside the 14 year old snapped, his sanity was a good bet. He locked eyes with the former professor. Never breaking eye contact, he had his mind made up.

"Baymax destroy! Destroy him!" Hiro ordered taking the healthcare chip out of the armored robot leaving the fighting chip he had made days before. When Baymax protested Hiro slammed his access port closed. He didn't care if it violated Baymax's health code or not. That wasn't his problem. His problem right now was Callaghan. Callaghan's words rang in Hiro's ears they wouldn't leave his mind.

"His mistake…his mistake…his mistake…" Hiro mumbled to himself, "Well that was your mistake! Get him Baymax!"

Callaghan tried to get out of the way, but without the microbots he was at the mercy of a 14 year old. Callaghan looked in the boy's eyes, his eyes were merciless. The boy meant business when he ordered for the demise of himself. The boy chuckled as he watched Callaghan squirm to get away from Baymax.

"Hiro! What are you doing man? This isn't cool!" Fred shouted tackling Baymax in an attempt to help Callgahan. The other were doing the same thing, doing their best to keep Baymax off Callaghan.

"No! Stop! Who's side are you on?!" Hiro shouted angrily. Were they betraying him? Why were they trying to protect a low scumbag like Callaghan? He took Tadashi from them, from him! He had to pay for what he has done! It only seemed fair..an eye for an eye…a life for a life.

"Tadashi wouldn't want this Hiro!" Honey Lemon gasped as Baymax flung her against the wall without an effort.

"You wouldn't know what my brother would have wanted! This is what he would want, revenge….revenge on the man who took everything…" Hiro said through clenched teeth. He looked at his hand that still held the mask that could control the microbots. He couldn't let his friends let Callaghan off the hook. Were they even his friends anymore? Friends wouldn't betray him like this. He had to stop them before it was too late. He looked down at the mask. Blinking back tears he threw off his helmet and replaced with the mask. He had to stop the traitors. He couldn't stop them by himself physically, but with the microbots he could pin them all. Then Baymax can finish the horrific deed, watch as Callaghan begged for mercy he wouldn't get. His mind blinded by anger and grief he turned towards the traitors who were still trying to protect the former professor. It disgusted him. Hiro controlled the microbots, one by one they wrapped around them. They couldn't move, struggling only made the bind tighter.

Good, now to deal with Callaghan….

"Hiro! Whats gotten into you?!" Gogo struggled within the bind.

Hiro ignored her, "Baymax..Stop." he instructed. Baymax retracted his rocket fist and obeyed. Callaghan was shaking fearful for his life.

Hiro found this amusing, he lifted the mask so Callaghan could look him in the eye. The grown man on the ground looked as if he was about to plead and beg him to stop. He smirked at the gestures.

"Hiro..you can't do this. Please..I'll do anything, Hiro do you hear me?" Callaghan pleaded with the boy. He could risk it and take the boy out easily, but he was at a disadvantage. Hiro had Baymax at his command and the microbots. Callaghan was at the boy's mercy. He scanned his facial expressions and his eyes for any signs of remorse from the boy. Still all that was there was anger and hatred for the man, his eyes were merciless.

"What makes you think you deserve to live?" Hiro scoffed. Callaghan was prepared to argue but the 14 year old cut him off, "Rhetorical question.." he said coldly.

"He's gone off the deep end!" Wasabi said out loud, Hiro ignored the comment and continued to walk towards Callaghan laughing with each step.

"Hiro please…" Callaghan tried to plead again.

Hiro shook his head, "This..this is what you get for taking my world..no my everything from me! Baymax..Finish him!"

Baymax aimed his fist point blank at the ex-professor who in return went pale. This..this was it. This was how he was going to go. The boy was not going to spare him. He failed. He failed his daughter's memory. He vowed to avenge her but that clearly was not going to happen, instead he would reunite with her in the afterlife.

Hiro smirked when the deed was done, he could hear the others gasping, they couldn't believe he actually went through with it.

"Hiro! We didn't sign up for this!" Wasabi said struggling to get out of the microbot's grip on him without success.

"Yeah you went too far man!" Fred chimed in.

Hiro only turned to them he had a crazy look in his eyes. He was grinning.
