Hiro had no idea what to say. There he was standing next to the short, green alien whose head shaped like a cube; Adu Du.

They were in what was formerly his brother's lab with his own friends as well as BoBoiBoy and his friends (including Probe and Ochobot). With Gogo and the others amazed the children (and robots) with their creation, Hiro temporarily left the group to relax for a bit. That was when he found himself with Adu Du and boy did that got awkward.

From what he knew, the purple robot (Probe) that somehow acted very human (in fact too human) was pretty much Adu Du's sole companion before the latter befriended BoBoiBoy. That reminded him of Baymax for some reason, which was currently deactivated.

Now he was curious about the alien's history with his robot companion.

"H-hey, there" Hiro started awkwardly, causing the alien to turn to him.

"What do you want?" Adu Du asked, in a slightly annoyed tone.

"H-hey don't be that moody" Hiro said before he coughed for a bit and started speaking again.

"It's just that… I really want to know more about you and your robot buddy there" he said as he pointed to Probe.

"By that you mean?" Adu Du asked in puzzled tone and expression.

"Well… h-how did you two m-met?" Hiro stuttered. He was not used to talking to an alien like Adu Du. If Adu Du had eyebrows to begin with, he would have raised one at the question.

"Why would you ask me such a thing?" Adu Du asked.

"W-well… I'm just curious I guess" Hiro said nervously. Adu Du sighed.

"Sorry… I'm not really in the mood. Even BoBoiBoy doesn't know the full story" Adu Du said as he looked away. Hiro sighed in disappointment. There was only one other way he could convince the alien.

"If that's the case…" this got Adu Du's attention.

"Let me tell you my story then… not everyone knew the whole story either" Hiro said slowly. Adu Du wondered why the boy was so insisted on him telling the story. Then again, there might be something interesting he could get out of it so he decided he should listen.

"Tell me then" Adu Du said. Hiro faintly smiled.

"When I was a kid, I was already some kind of genius. But I got bullied a lot by my classmates because of that. Thankfully my brother was there for me" Hiro started. Adu Du stared wide-eyed. It seemed familiar to his childhood, except that it was not because of his genius.

"You know… I was like that too" Hiro was nearly startled when Adu Du said that.

"Well except my brother wasn't really there for me. I was really bullied because… well I'm born from the lowest class in the community of my planet. All I'm supposed to do was pick up the mineral remains" Adu Du said. Hiro only stared. Just the beginning of the story and there was already some similarities. Maybe they had more in common. Only one way to find out. That was when he smiled.

"Back to my story… I ended up graduating early from my school and by the time children my age should be in middle school, I was already done with school. I found my love for bot fighting, which is illegal mind you, and my brother, Tadashi had to bail me out. As the caring big brother he was, he of course wanted me to quit it. I guess he got tired of our Aunt Cass whining all the time whenever she found out" Hiro continued. That was when Adu Du realized that Hiro never mentioned his parents.

"What exactly… happened to your parents? I noticed you never mentioned them" Adu Du said. Hiro was surprised by the question. An alien was the last person Hiro expected to ask about his parents anyway. But he knew he had to answer.

"They… were dead when I was three. I never knew them well" Hiro explained sadly. Adu Du was slightly shocked at the response. He did not know what to say about it aside from apologizing for bringing up bad memories.

"H-hey. What did you do during your childhood? Anything that's really cool?" Hiro asked before Adu Du could say anything about Hiro's parents as the boy wanted to avoid talking about his parents.

"Oh? Uh… oh yeah, I think I did. If I wasn't mistaken, I built a robot when I was two" Adu Du said causing Hiro's eyes to widen. Hiro was not wrong to assume the two had very much in common, though he did not expect that part. Then again, this was an alien so it might not be very surprising back at his home planet.

"Wow, I'm really sur-"

"How about your brother, then?" Adu Du interrupted before Hiro could finish giving his comment about Adu Du's earlier statement. Hiro's eyes widened at the question.

"What do you mean?" Hiro slowly said in a nervous tone.

"He's… dead too, right? What happened?" Adu Du asked in a serious tone without even looking at Hiro. Hiro went silent for a while, as the memories of the incident still fresh within his mind. Should he go straight to the fire or he could use the opportunity to continue the story like he should've been?

"At some point before his death, he brought me here, to this… place where I met his friends, who are now mine as well" Hiro said in a slightly said tone.

"He took me to this very lab we're in right now and showed me what he was working on. That… was when I met Baymax, my personal healthcare companion" Hiro explained with a faint smile on his face. Adu Du watched the boy with interest. He wondered what would happen should Probe had a similar function to Baymax.

"After looking at everything I've seen at the lab, I've decided I wanted to sign up for this place and thanks to Tadashi, I've got the chance to. There was this expo or something I don't remember, and my project was a bunch of Microbots" Hiro explained. Adu Du was mostly intrigued with the Microbots Hiro made.

"What do the Microbots do?" Adu Du asked.

"When I made those, I also built a neurotransmitter that allows its wearer to control them at will. It was meant to do anything we want, be it construction or transport or anything for the greater good. It worked and I got accepted. But then... as I was about to celebrate my success…" Hiro paused, a single tear appeared on his left eye.

"What happened?" Adu Du said, showing his interest into the story.

"There was a fire, and Tadashi rushed in to save someone…" Adu Du noticed Hiro had put an emphasis on the word 'someone' and seemed slightly angry at it. He wanted to ask but he should let the story continue for Hiro's sake.

"I tried to stop him but… it was too late. He died… and I separated myself from others. All I had was Tadashi's cap, and… Baymax" Hiro sadly said, nearly crying at his own retelling of the events. Adu Du suddenly felt guilty for asking about his brother.

"Hey… if you want to stop for a bit…" Adu Du said in a sad tone, obviously feeling guilty.

"It's… okay. What happened has already happened" Hiro assured as he wiped his tears. He then gave a faint smile at Adu Du.

"Shall I continue?"

AN: Hi there! Originally this was supposed to be a one-shot but looking how long this chapter is (1K is already much thank you very much) I had to sign off here.

Once I finished watching Big Hero 6, I felt like it was a bit familiar and then immediately connected the dots, though I had to say Big Hero 6 done it better. But still this was awesome! Hopefully you'll like it.

I don't own neither of this as you all know, so review, fave and maybe follow this story! See you next chapter!
