Sorry this took a while. Just got done with finals and needless to say, life got a little stressful. Also, sorry this chapter's a little short but hopefully you guys will like it anyways!

Sitting in his room, Hiro closed the tab on his computer and spun around in his chair, bored out of his mind. He had tried to find himself any kind of distraction from what he had learned yesterday, but none seemed to do the trick.

Thankfully, his phone began to ring before he started ripping out his hair. He quickly answered it as he stood up and jumped onto his bed, lying down and staring at the ceiling as he answered, "Hello".

"Dude! TV! Channel nine!" shouted Wasabi.

Hiro sat upright as he tried to think of what was so important that he needed to turn on his TV right then and there. "Why? What's up?" he asked as he got off of his bed and began to move towards the stairs leading to the living room.

"Just turn it on! It's Krei!"

Now Hiro understood the importance. "What's happening?" he asked as he rushed down the stairs.

"Nothing yet," Wasabi answered.

Aunt Cass was still downstairs in the café, the lunch rush just now beginning to dwindle down, so Hiro had the room and the TV all to himself. Grabbing the remote, he turned the TV on and pushed the button marked 'nine' and waited for the channel to appear. Sure enough, just like Wasabi said, Krei's face was onscreen in some kind of news report.

"Ooookay, so, what? The news is doing some story on Krei?"

"Just wait," Wasabi assured.

"Is he watching?" Hiro heard Fred say in the background.

Wasabi was quick to silence Fred. "Yeah, yeah he's watching. Sshh."

Hiro watched as the picture of Krei changed to a panning shot of some new building that was being opened in town. A pedestal with microphones attached was waiting at the front, behind it a long red ribbon as if an opening ceremony was about to commence. As the news story went on, the anchor explained that Krei was going to officially open the building later that day and was sure it was going to be a wonderful ceremony.

"What does this have to do with anything?" Hiro asked.

"We think he's gonna be there."

"Krei? Of course, he's opening the building, right?"

"No, not him, dude. Tadashi."

Hiro almost dropped the phone. The sudden realization of what this could mean made him want to sit down, but his eyes were kept glued to the TV screen just in case something might happen, though he didn't know what. "So-so what makes you think Tadashi would be there?"

"Well we all thought Callaghan might go after Krei, right? This would be the perfect time! He's out in the open about to unveil some project or something, I dunno. It seems like the perfect opportunity!" Wasabi was fast when he spoke, his words almost slurring together. Hiro could hear keys shuffling on the other end as Wasabi continued, "Fred and I are gonna go get Honey and Gogo. We'll be by your place to pick you and Baymax up, then we can get our suits and go over to where Krei is and watch out just in case-"

"Woah woah woah!" Hiro interrupted. "Suit up? We don't even know if Tadashi or-or even Callaghan are gonna be there! Shouldn't we, I dunno, wait or something?"

"Hiro, it could be too late if we just sit here and wait for Tadashi to show up. We need to be there to stop him if he does try anything."

Hiro sighed, knowing Wasabi was right, but wasn't looking forward to having to fight his brother. He knew Tadashi was stronger than he was physically, and even then he had that army of microbots to help him. Hiro just had to hope that this time, Baymax and the rest of his team would be enough to stop him. Hiro gulped, trying to gather himself as he turned off the TV and went back upstairs. "So, uh, when do you think you guys will get here?"

"Soon, hopefully. Just have everything ready when we do. We need to get there as soon as possible."

"Yeah. Yeah no worries, I'll, uh, see you when you get here. Be safe."

As Hiro ended the call and entered his room, he looked over to Baymax and gave him a friendly nod. "Hey, Baymax. Looks like we're going after Tadashi sooner than I thought."

"Oh?" Baymax asked. "Have you located him? My scanners have yet to pick anything up. Perhaps he is still hiding in a protected room."

"No, no we haven't technically found him. We just think we know where he'll be," Hiro explained.

"Should we, 'suit up?'" Baymax asked, stressing out the last two words as if it was a phrase he still didn't yet understand.

Hiro grabbed his shoes and slipped them on as he sat on the edge of his bed. "Yeah, in a minute. Everyone's gonna meet up here before we head out to watch Krei."

"Do you believe Tadashi wishes to harm Krei? Is that why we are going after him?"

"That's the plan," Hiro answered as he slipped on his second shoe. He stood up and adjusted his shirt as he grabbed his jacket and walked over to Baymax. "You ready, Baymax?"

"I will be. Just as soon as I put on my protective and flying gear," Baymax answered.

Rolling his eyes, Hiro headed downstairs and made his way to the lab. He had no idea how any of this was going to turn out. But he knew that he was going to try his best to end it all today. One way or another, he was going to get his brother back.

As Tadashi put on the trench coat, he heard a knock on his door. He didn't need to say anything before Callaghan entered and folded his arms as he leaned on the doorframe. "Are you ready?" he asked.

"Almost," Tadashi answered. He grabbed the mask off of the hook it was hanging on and placed it on his head, adjusting it and making sure it was in the right position so he could see as much as he could out of the narrow eyes on the mask. "Ready," he answered.

"Good," Callaghan said as he moved out of the doorway and gestured out of the room. "It's time."

"See anything yet?" Gogo asked as the team, flying on Baymax, made their way over to the building Krei was unveiling.

"Nothing yet!" Honey responded, looking around for any sign of the microbots. "Are we sure he'll even show up? It's a bit obvious don't you think?"

Wasabi shook his head as he looked at her. "No, it makes perfect sense. He's out in the open so he might as well get him while he can!"

"But why does he need the machine?" Fred asked, still keeping his arms up as if he was Superman flying over the city with a protective and watchful eye.

"Guess we'll find out soon enough," Gogo answered.

"Sooner than we think!" Hiro shouted as he pointed ahead of them. "Look!"

The team looked ahead and saw the building, still a ways off in the distance, being swarmed with microbots carrying three large curved pieces over the building. When they were connected, a bright light started sucking everything up as if it was a large vacuum.

"The teleport!" Wasabi exclaimed! "He's using the teleport!"

"Yeah we can see that genius!" Gogo shouted back. "What do we do now?"

"Turn that machine off! I'll deal with Tadashi!"

As the group hurryingly made their way over to Krei, Tadashi held the man up by his shirt, forcing him to watch as his building was sucked into the teleport bit by bit.

"PLEASE!" begged Krei. "I-I'LL GIVE YOU ANYTHING! JUST LET ME GO!"

"It's too late for that," answered Tadashi. "I've been instructed by my master to make sure you don't come out of this alive, so if you have anything to confess or ask God forgiveness for, I'd do it now."

"Your master?!" Krei asked as he heard windows shatter beneath him. "We-well who? Who's your master? I can reason with him! I'm a reasonable guy! Come on!"

Tadashi tried to hide his laughter at Krei's useless pleading. "I'll tell you who sent me. But you'll gonna have to wait a little bit. Just enjoy the show for now."

"TADASHI!" Hiro screamed, grabbing the masked man's attention. The team landed in a safe distance on the entryway to the courtyard in front of the building, Hiro jumping off of Baymax and taking a couple steps closer to his brother, reaching out as he tried to calm and reason with him. "Put! Him! Down!"

Suddenly, at the sight of the boy, Tadashi remembered a few vague details about their last encounter. His face, his voice, the name he called him before. But none of it meant anything. All he remembered about the boy was that he would stand in his way of completing his mission, and the only thing he could do was get rid of him and the rest of his friends. The robot would especially be difficult, but with as many microbots as he had at his disposal, it shouldn't take too long.

Tadashi had his microbots wrap around Krei and hold him position. "Don't go anywhere," Tadashi commanded as he floated higher up to be at an eye level with the boy.

"Tadashi please, don't do this!" Hiro pleaded. "I know you're in there somewhere!"

Tadashi said nothing as the boy shouted nothing but useless begging. He took note of how his friends were getting ready to attack, readying their weapons waiting for the moment he would make any kind of move to attack them. Tadashi readied his own weapons, slowly advancing on the team as he said nothing in response to the young boy's exclamations.

"Hiro," Gogo whispered as she grabbed her discs, "I don't think Tadashi wants to talk right now."

"Just let me try! Don't do anything, if we're gonna fight then at least wait until he makes the first move!" Hiro turned to look back at his brother, this time reaching out to him with both hands as he went on. "Listen, we don't want to fight. We just want to talk."

Still, Tadashi said nothing. This time, he sent a blast of microbots at the group, separating them all as they dove in different directions in order to evade the attack. Sending the microbots after each member of the group, Tadashi focused his attention on the smaller boy who had just climbed onto the back of his robot companion.

"BE CAREFUL, GUYS!" he called out to the rest of his team as the fought their way through the army of tiny machines. He turned to look back at Tadashi just in time to see Baymax block another attack, tiny microbots flying right past Hiro's head. "Just listen to us!"

Tadashi ignored everything the boy was saying, something about him seeming…off.

Though he wished he could stay focused on Tadashi, he knew he had to stop the teleport before it sucked up the rest of the building. If it was unstable before then it was sure to be unstable now. Hiro knew he couldn't get too close to it or else risk being sucked into the portal himself, so there was only one logical way to destroy it. He had to get the mask off of Tadashi. He'd lose control of the microbots, and then the tiny robots holding the machine up would fall apart thereby breaking the teleport and stopping Tadashi from carrying out whatever plan he had.

"We need to get that mask, Baymax. Think you can handle it?"

"As long as you are not hurt, then yes. I do believe I can get it."

Tadashi sent another blast at the duo before they could say anything else to one another. As Baymax protected Hiro from the attack, Hiro looked around to try and see how his friends were doing. For the most part, they seemed to be doing really well against the microbots. Fred seemed to be having the most fun; Hiro could hear his screams even as high up as he was through the sound of the microbots

All of a sudden, Hiro had an idea. It was a crazy one, but one he knew had to work. When the attack was over, Hiro reached out to Tadashi again and shouted, "WAIT!"

Tadashi stopped, curious as to what he would try to say next to get him to change his mind and actually listen to whatever absurd thing he had to say next.

Hiro, slowly and cautiously, took off his helmet and smiled at his brother. "Tadashi," he spoke, "please, listen to me. It's me, Hiro. You remember me, right?"

Tadashi remained silent, but not for the reason Hiro assumed. The boy's face was familiar to Tadashi. So familiar, he practically froze where he stood. His arm began to lower as he tried to make sense. Tadashi? Hiro? He had never heard these names before but yet it seemed as if he had known them his whole life. Callaghan had warned him that his enemy would try to play tricks on him, but he didn't say something like this would happen. He had to stay silent, that much was certain. He raised a hand to attack, but still the boy kept talking.

"Just hear me out!" Hiro said as he stepped down from Baymax.

"Hiro, I would advise you to stay behind me as I can withstand his attacks whereas you could fall off and injure yourself," Baymax said as Hiro stepped towards his brother.

"I-I'll be fine, Baymax, trust me," Hiro responded as he kept his helmet close to his side. "Tadashi, do you recognize me?"

Tadashi stood there, not moving a muscle. The only part of him that moved was his coat flowing and flapping through every gust of wind that passed by.

"I'm your brother. You remember Baymax?" Hiro asked as he turned to motion towards the large robot. "I mean, you probably don't recognize him now, sorry about that, but-but you built him. A healthcare companion, remember? You built him a-and you helped me build these microbots. For the expo, do you remember that?"

The expo. Tadashi flinched as yet another memory came back to him. A fuzzy memory at that, but a memory nonetheless. Something about a fire, and tiny robots. A puzzle was beginning to form inside Tadashi's head, but he had no idea what kind of picture it was turning out to be. He looked away from Hiro as he tried to clear his head. He had underestimated what kind of trickery this kid was going to do, but he wasn't about to let him do it again. He raised both arms, a large wave of microbots forming behind him as the Krei building continued to be destroyed.

"Aunt Cass!" Hiro screamed in a panic, stopping Tadashi from doing anything else. "A-Aunt Cass! In the café! Your favorite donut was the-the chocolate crème filled one with the chocolate frosting! She kept making them because you said they were your favorite even though no one bought them that much! We have lunch with her every Saturday! Sandwich and salad, remember?"

Tadashi was beginning to get a headache, and a painful one at that. All of these things this boy was telling him made no sense, but yet they echoed throughout his mind as if they were something he had known long ago. They rang with truth, try as he might to shut them out.

"Do you even remember your own name?" Hiro asked. "Tadashi, please, at least tell me you know your own name. Tadashi Hamada, come on at least say it! Your name is Tadashi Hamada!"

"MY NAME!?" Tadashi screamed, using the microbots to move himself closer to Hiro and getting almost two feet close to him before Hiro could even take a step back. "My name," Tadashi said as he flipped his mask up, revealing his scarred and anger-filled face, "is Yokai."

Hiro almost wanted to scream. There had to be a way to get through to him! "No! No it's not! It's Tadashi Hamada! I'm your brother, Hiro! Do you see those guys?" Hiro pointed below to his friends, still teaming up to fight whatever microbots came their way and more than likely worried that Hiro was in more danger than they were being up there trying to reason with Tadashi. "Those guys are your friends! Wasabi, Fred, Honey Lemon, Gogo! From school!"

Tadashi looked down at the colorful team of heroes, pausing as he tried to process what Hiro was telling him. "Hon…Honey Lemon?" he asked before grabbing both sides of his head and groaning in pain. This wasn't right! None of this was right! None of this made sense! His head was screaming as he tried to figure out what this meant. What any of this meant.

"YOKAI!" someone called from below. Hiro turned around to see someone standing by themselves, looking up at the three of them with their hands by their side.

The man didn't need to say anything else before Tadashi used the microbots to descend and get closer to the man. "Sir, I was just going to-"

"Take me up there. I want to speak with him."

Tadashi was confused, not knowing why on Earth Callaghan would want to speak with the kid. "But sir, I don't think-"

"Now, Yokai."

With a sigh, Tadashi responded with, "Yes sir." Begrudgingly, Tadashi had his microbots form around Callaghan's legs and carry him up alongside Tadashi.

"Who is that guy?" Hiro asked as he watched as the two came closer and closer, setting his helmet down and anticipating the arrival of the strange man.

Once Callaghan was close enough to see Hiro, he folded his arms and slowly shook his head. "Tsk, tsk. Well you just had to poke your little nose into other people's business, didn't you?"

Hiro didn't know what to do. His anger and confusion was starting to boil inside him, ready to explode at any moment. "You…" was all he said at first as he stepped closer to Callaghan. "We were right. It was you! You-you're behind this?"

"Oh, well I can't take all the credit. Yokai here has done fantastic work himself."

"His name isn't Yokai. It's Tadashi!" Hiro urged, looking at his brother, waiting for the moment everything would click into place

"I'm afraid you're wrong there, boy." Callaghan looked at his counterpart and said, "Yokai. Give us a moment please."

Tadashi nodded and moved away from the two, floating down away from the two and giving them their privacy as he looked down at the other heroes fighting the microbots and turning all of his attention towards them, making sure that they wouldn't get the upper hand so easily.

"Hiro, Hiro, Hiro, why couldn't you just let things be? It's not like I'm hurting you. I'm just doing what's right. So why don't you be a good little boy and-"

"STOP!" Hiro screamed, his hands slowly starting to form fists. Even Baymax was ready to attack and go after Tadashi whenever Hiro gave him the word. "You're using him. And for what? Revenge? This isn't going to bring her back, Callaghan!"

"You don't think I know that?" Callaghan shouted in reply. "You think I don't know that Abigail is gone forever? Because of him! I've already talked to that monster; he knows who's really behind all of this. I could get rid of him right now if I wanted to, but I'd rather he enjoys the show while he still can."

Hiro shook his head as he took another step closer to the older man. "Listen to me. Give. Me back. My brother," he commanded. "Do it and we won't bother you."

"No can do, son," Callaghan answered without any hesitation.

Hiro clenched his teeth as he looked down at his brother, his mask still flipped up as he watched the battle below ensue. "How does he not remember us? How did he forget everything?"

"Simple," Callaghan went on to explain. "At the expo last year, one of the students invented a machine that could scan a person's brain and project their memories for all to see. He won, of course, and soon became a student at the university. While he did his own research and projects after moving on from the memory machine, I simple made a few adjustments, tweaked a few things and voila! Memory wipe technology was possible. Of course I had to do my best to keep it a secret, but that was the easy part."

"But why him?" Hiro asked. "Why Tadashi?"

"Simple. He went in after me."

"What?"

"I started that fire to plan my escape. I needed to disappear for a while. When Tadashi came in and saw me using your microbots to protect myself from the fire, his head was hit by a falling beam, knocking him out." Callaghan looked at Tadashi as he continued, "I went to save him, but I wasn't able to save all of him. I treated his wounds before he woke up, and as soon as he did I used the memory swipe to alter his mind and have him think exactly what I wanted him to think."

"But why him?" Hiro asked. "Why did you even need him in the first place?"

Callaghan chuckled, shaking his head slightly as he answered, "Well isn't it obvious? I had to disappear, Hiro. If he was caught he was told not to let anyone know that I was in charge. If he was seen without the mask on, people would suspect it was him, not me. I had to protect my own identity too you know."

"And if Tadashi wasn't there that night?"

"I would have used someone else. Tadashi was just, if you want to look at it this way, at the right place at the right time."

Now it was all starting to make sense. Hiro looked down at Tadashi and bit his lip, trying to think of what Callaghan would do with him when this was over. "He can't work for you forever."

"And why not?" Callaghan asked.

"He's my brother! He needs to come home!"

"Oh Hiro," the older man responded, "I'm not stopping here."

"What do you mean?"

"I mean after I'm done with this so-called 'Technology Institute', I'm moving on to bigger things. Yokai will be a better vigilante than your pathetic attempt at being a supposed hero."

Hiro was starting to get confused again. "A vigilante?" he asked. "What, you're just gonna set him loose and tell him to protect the city or something?"

"Set him loose?" Callaghan repeated. "Why, of course not. He'll still work for me of course, except he'll be the one in the field. And with his microbots and my intellect, this city will have no choice but to listen to me. Soon I'll make sure that no one will have to go through the same pain I went through when I lost my Abigail."

"It doesn't have to be this way, Callaghan!" Hiro implored. "Please, just let my brother come home! This isn't going to work! You think just because you get away with Krei we'll stop fighting? We made a promise, Callaghan! They're getting their friend back, and I'm getting my brother back!"

Callaghan only smiled in return before looking down and whistling towards Tadashi. "Yokai!" he called out, getting the boy's attention. Tadashi rose towards the two, keeping his eyes fixed on Callaghan and refusing to look at Hiro the whole way up.

"Sir," he said.

"Take care of him would you?" Callaghan told him, looking at Tadashi with the same smile he had given Hiro. "I'd like to go have another chat with my dear friend Alistair Krei."

"Yes, sir," Tadashi responded as he looked to Hiro and moved in-between the boy and Callaghan.

"Well it was fun, Hiro!" Callaghan said as Tadashi moved between them. "If you're smart you and your friends will leave now while you still can."

"You can't do this Callaghan!" Hiro shouted. "You can't do this to him! He looked up to you! He trusted you!"

Callaghan only smirked as he replied, "That was his mistake."

Hiro took a step back in shock at the man's response. Whatever kind of man he thought Robert Callaghan was before was obviously wrong. This kind of man was dark, cold, and had no problem with letting one brother fight the other.

"Yokai, if you please," Callaghan politely asked.

Tadashi had the microbots slowly carry Callaghan back to solid ground, Hiro all the while picking up his mask and holding it with both hands before he gave one final attempt at making his brother see the truth in what he was about to do. "Tadashi, please just listen to me. You don't have to do this. You can still stop this. All of this. You can come home. With me, with Aunt Cass, Baymax, your friends, we all just want you home."

"Tadashi," Baymax said, getting the attention of both the boys. "I feel as if it would be beneficial to Hiro's health if you did come home. His neurotransmitter levels I feel would increase greatly, thus completing his treatment."

Tadashi only scoffed at the robot and turned his attention back to Hiro. "You just don't get it do you? I'm not this person you think that I am."

"Yes you are!"

"NO I'm NOT!" Tadashi cried out. "My name is Yokai! I work for Callaghan! When we're done with Krei, we're going to protect this city from anything that tries to hurt anyone. And if that means I'll have to stop you, just a little kid, then so be it." Tadashi moved his mask back in front of his face, raising up both arms and calling his microbots to him.

Baymax took a few steps closer to Hiro, leaning over on bended knees as he said, "Hiro, I advise you to get on. You would have fewer chances of getting hurt on my back as you would standing in the open."

Regretfully, but knowing that what Baymax said was true, Hiro got on Baymax's back and secured himself on the magnets. As much as he didn't want to believe it, Tadashi was meaning to hurt him, his own brother, in order to get what he thought he wanted. "Tadashi, please. I'm your brother."

"No," the older brother responded. "You're not." As he spoke, the microbots arrived and formed several circular clusters with spikes on the end, ready for the attack on Tadashi's command. Tadashi raised one outstretched hand to the duo and uttered, "The only thing you are to me," closed his fist, "is in my way." With that, Tadashi quickly opened his hand, stretched out his fingers, and sent the army of microbots at his own brother.

So yeah that happened.
