Welcome Back! This is the first installment in the HGUniverse ( HiroGoUniverse ). Please be sure that you read the introduction to the HGUniverse as reference will be mentioned as well as this being a continuation. As mentioned in 'HGU - The Beginning', the pairings and same principles apply. I did, however, fail to mention the ages. So here they are with an explanation as to why.

Hiro: 14 - As that's what his age was stated in the movie. 1st Year SFIT.

GoGo: 16 - Like Hiro, she's a genius as well. 2nd Year SFIT.

Fred: 18 - My friends all think I'm Fred myself so I made him my age: SFIT Mascot

Honey Lemon: 19 - Acts like a typical 19 year old these days: 2nd Year SFIT

Wasabi: 21 - The most mature and will help with a certain story later: 3rd Year SFIT

Aunt Cass: TBA - Need help from readers with her.

P.S. I'm also basing Fred off of me a bit, but it won't be too noticeable considering I honestly act a lot like Fred minus the comic book stuff, which will still be in their.

P.P.S. I'm saying the movie ended on January 1st, 2015. For Birthday reasons.

Anyway! I just wanted to say a big ARIGATO* to everyone. I posted one story and are favored by two wonderful individuals: Baymax 2.0 & KanashiNaito. Arigato, both of you. For this story, as foreshadowed before, Callaghan has indeed returned looking for revenge. He knows about his daughter but still wanted his revenge on BH6 as well as Krei. Projected to be a few chapters. I have a trip coming up so I'm going to write as much as I can to upload in intervals as I'm away. Anyway! AWAY!

*Arigato: Japanese for 'Thank You'. Been teaching myself lately.

Two months. That's how long it's been since GoGo had gotten out of the hospital. One and a half since they robbers they took down at the bank got out of jail. And one month since they were found dead cut up into...well a lot of pieces. And they still haven't found ANY evidence of who did it. They had decided to stop looking, it'd been a month since. Plus the group, minus Hiro, where planning for Hiro's surprise party. They young leader would be turning 15 in about ten days, and the group wanted to do something special with the help of Aunt Cass. With how much everyone spent at the Lucky Cat Cafe, everyone had taken to calling her Aunt Cass now. A sign they were a part of the family.

Twas the night of June 1st, ten days before Hiro's birthday and the group where all in the Nerd Lab working on their projects. Wasabi was using some of the breakthroughs from his suits plasma blades to perfect his project and make saw's and tools that could be used to cut open overturned cars or cut building materials away to get to injured or trapped people. Honey Lemon was working on a new thesis on her blue goo formula that restrains people during her fights. Fred was reading his comic in his favorite lounging chair now positioned next to Honey Lemon's lab. And GoGo was still working on making her bike faster, going thru the calculations on her skates for her suit.

Hiro was just wrapping up his new upgrade chip for Baymax. The one original chip, with Tadashi's name, was never touched. Instead a new chip, colored yellow with simply the name 'Hamada' written on it was Hiro's addition. It would have the few bug fixes needed to be fixed on Tadashi's chip as well as more healthcare programing and articles on what to do in certain situations. As well as program 'BH6P'. This program was created as a safety precaution. Under NO circumstance can Baymax harm the group of Big Hero 6. On top of that, the green and yellow chips can not be removed unless Baymax is completely shut down and Baymax can not activate without the green chip, meaning the event can never be a repeat of what happened in the fight with Callaghan.

Alongside the green and yellow chips lies the red one marked with a skull and crossbones. This is Baymax's fighting chip, uploaded with a mix of fighting styles like, karate, MMA, and Kung Fu. With the help of his sensor scanner Baymax knows when to use full force, like against robots and such, and when not to, like against humans and animals.

Hiro slide in the yellow chip in between the green and red ones with the new bug fixes and general improvements. It took Baymax a minute to process and update his programing with the installation but after it was done he blinked and looked at Hiro giving him a "Complete". Hiro smiled and nodded and went and cleaned up his station space.

Hiro came out of his station after shutting down Baymax. Closing and locking the door he and Baymax walked down the hall towards the more open part of the lab. Once there he stood and looked at all the projects going on. Once he sat his eyes on GoGo's station with her hunched over looking he walked over to her, waving to Wasabi as he passed. Once at GoGo's station he peered over to look at her. She was looking at the schematics for her suit seemingly trying to figure out how it worked, not even noticing the youngest member of the group besides her.

Hiro tapped her shoulder causing her to jump slightly and without even looking behind her saying,"Go away Fred!". Causing Hiro to stifle a giggle.

"Is that anyway to treat a friend Go?" Hiro asked hand on his hip with a smirk. At hearing this GoGo froze and had a blush on her face. Shaking it off she turned her head to look at Hiro and smirked when she saw him.

"Oh, hey Hiro. I thought you where Fred coming back to bug me again." She turned back to her schematics and began to go over them for the hundredth time.

"Do you need help with that Go? You know, I did write them after all." Hiro moved over to stand next to her.

She looked up to him,"Ugh fine….but not because this means you're smarter than me, I'm just tired, that's all." She said looking back to the schematics. "I'm just trying to figure out how you made there be no resistance between the wheels and the suit."

"Let me look at the magnet of your bike wheel really quick." Hiro grabbed one of her wheels and unscrewed the cover. Upon looking at the magnet. "Aw here we go. You're using a full circle magnet. See in your suit I used hollow magnets. Less weight and a better connection." Hiro said with a smirk looking at GoGo.

She was staring at her wheel magnets, Why did I never think of this! Thats brilliant! God he's so smart... and cute. What no! Why'd I'd think that? Cause it's true. Well yeah but…..ugh! Whatever. I still can't believe I never thought of using hollow magnets. I mean, they even are one of the top rated in my book! GoGo shook her head and looked up at Hiro, popping her gum,"Good idea. Now all we need is some hollow magnets. I'll put in the order with the school."

"Well in the meantime, I have some extra in my garage if you want me bring them tomorrow so you can get right to work." Hiro said walking over to the only stool in her work area.

"If you don't mind yeah. The faster I can test that the better." GoGo said with a slight smile. She started putting up her things and cleaning her station. After cleaning she turned to look at Hiro who was playing with a pencil in his hand."Hey..uh..thanks for..you know, helping me with my bike. I don't know why I never thought of that but still, thank you."

Hiro looked up at GoGo who had a small blush,"Oh uh..your welcome. I only tried those cause that was the only magnets I had after my last project." Rubbing the back of his neck laughing nervously.

"Last project? You mean you have projects from before SFIT? What kind?" She had never asked or been told Hiro had done projects before, other than Baymax. She was curious.

"Oh! Uh...ya know...just..uh...bots and such...for..you know...bot fighting…" The last part was said so quietly she almost missed it, but once she realized what he said, her eyes went wide. She never thought that Hiro, the brother of Tadashi, was once a bot fighter. And look what he's doing now. I mean, it was crazy to her. Especially since she was one herself at a time.

"You! Where a bot fighter? Really!? I would've never thought that Hiro Hamada was a bot fighter!" Hiro was extremely embarrassed now and worried. He was worried that she would tell the group and they wouldn't want to be around him or something. But what he didn't expect was what she said next,"I bet you where no where as good as me."

That made Hiro stand frozen for a second. He took a moment to process what she just said. GoGo was a bot fighter? "You were a bot fighter to?"

"Yeah! Keep it between us though. I know Wasabi would hate it and Honey Lemon isn't the biggest fan of it either. But yeah, I would take my dad's bots out and fight them. Before he passed away of course but….I still have them to. I could you show you." GoGo said smiling.

Hiro visually was ecstatic,"That'd be awesome! I'd have to bring Mega-Bot with me to. How long ago did you fight? I was fighting after High school until Tadashi showed me the Nerd Lab, back when I meet you all."

"You mean that magnet looking thing you had in your hand? THAT's Mega-Bot!? That thing looks like It'd barely do anything. I'd suppose that's the point then huh?" GoGo smirked at that.

"OH yeah! I made him to look the least intimidating then I'd extend my controller and his face would spin with an evil one and completely decimate people. I was able to hustle the big bad Yama outta 2 grand!" Hiro said with an upbeat pose and a smirk on his face.

"Ah Yama. I remember him. He's the only one to beat me, taking my spot on the Bot Fight Underground. I almost had him to tha-"

"WAIT! So you're saying you're THE Tomago. Tomago the Underground Bot Fighter that reigned supreme for how long was it? Three years almost!?" Hiro was visibly stunned to say the least. Her she was, the bot fighting champion he looked up to in his time of fighting and now they're the best of friends.

"Yeah. I mean that is my last name you know right?" GoGo asked raising her eyebrow.

"No actually, I don't even know your full name." Hiro rubbed the back of his neck nervously."I mean, it's never come up or anything and I've never asked, hehe."

GoGo smiled,"Well that's alright, actually, I don't think the rest of the team know my name. Anyway, my full name is Leiko Tanaka. GoGo Tomago is my alter ego so to speak. Just don't go telling everyone alright. Gotta keep my image up ya know." GoGo said with a wink and popping her gum.

"Oh, well it's a nice name though, really. Speaking of everyone else, what are Honey Lemon and Wasabi's real name?" Hiro asked with a raised brow. It's not his fault for not knowing. He just simply never asked and no one ever told him. Till now.

"Ha, well here's the funny part. Wasabi, that's his real name, Wasabi No-Ginger. Honey Lemon on the other hand, her names Aiko Miyazaki. We call her Honey Lemon cause she can be sweet but sour when she needs to be." GoGo laughed at that. It was true, she was always like that when GoGo came home late or when any of the gang got into trouble.

"Ah, yeah I've seen that part of Honey Lemon before. Remember when you text me when you got home after your hospital visit?" Hiro asked, laughing remembering when they found out he got grounded for staying late at the Nerd Lab so much, sometimes passing out on the couch there.

"Yeah I remember, took me a month for her to not get so worried when we went on patrols." The both laughed at that. GoGo looked at the clock and realized it was 9 p.m. When she looked around she found everyone else had already left for the night leaving the two alone."Hey, looks like everyone left. You wanna come check out my old bots?"

"Yeah! Can we stop by and grab Mega-Bot?" Hiro said, super excited.

"Sure thing. Here, we can take my motorcycle." She tossed him her helmet as the walked out the Nerd Lab down the hall.

"Well...don't you need it? I mean.." Hiro said.

"Nah, I've got my suit in the bike bag, I can use my helmet in there." She smirked

The walked out the front of SFIT into the big open parking lot that houses all the students vehicles. Luckily for GoGo, she gets here early enough to get a spot right at the front. She went thru the bike bag and got out her suit helmet. Once on she jumped on the bike followed by Hiro, who cautiously wrapped his arms around her waist. Both had blushes on their faces while GoGo turned on the bike and the where off to The Lucky Cat Cafe.

The ride was quick, weaving in and out of traffic. At first, Hiro was scared doing so but after a while he grew to enjoy it. They luckily hadn't caught a single light as they reached the back side of the Cafe. Hiro jumped off and told her to wait there as he ran inside. Aunt Cass had already closed up and had passed out with Mochi in her lap in the recliner in front of the Teley. He rushed upstairs and grabbed Mega-Bot. While he was up there he paused when he caught sight of Tadashi's side of the room. He stood for a moment in memory, Don't worry Tadashi, I'm not bot fighting, again. He smiled as he walked down the stairs closing his door and back out the back. He jumped on GoGo's bike and they took off.

The ride was similar on the way to Honey Lemon and GoGo's apartment. Hiro visibly ecstatic and GoGo enjoying the speed. Again not hitting a single red light they made it to the apartment relatively quickly. They parked the bike outside and and removed themselves from it. GoGo removed her suit helmet and placed it back in the bike bag.

"So, enjoy the ride." She said smirking. Hiro removed her helmet and handed it to her.

"Yeah! That was awesome. I wish I could ride more often." Hiro said excitedly. He liked riding the moped with Tadashi but riding with GoGo on her motorcycle was just better, faster, and it was GoGo to.

"Well, considering I pass you Cafe on the way I could always give you rides. You'd need to get your own helmet though. I can't be riding around town with 'Speedy's' helmet and not cause controversy." GoGo said, to be honest, she actually liked the idea. She loved hanging out with Hiro. Just something about him.

"Really! That'd be awesome. I'll for sure get a helmet tomorrow. Thanks Go!" Hiro hugged GoGo. He didn't realize what he did but when he did GoGo had already, surprisingly, returned the hug. Although short, they both secretly didn't want it to end.

"Let's head up shall we." GoGo said, somewhat nervously. Hiro nodded and they head up to the third floor. Once they got to the door GoGo got out her keys, when she went to put them in the door slammed open, Honey Lemon was right there with her arms crossed.

"GoGo Tomago, where have you been? It's 10:00- oh hey Hiro." She went and gave him a hug.

"Hello to you too Honey Lemon." GoGo said as she walked in and placed her bag by the door. She went towards the kitchen to grab food and Honey Lemon followed by Hiro walked in the apartment."Hiro you hungry?"

"Uh yeah, I could go for food." Hiro said walking to the bar stool situated at the kitchen island.

Honey Lemon walked over,"GoGo where have you been? Like I said it's 10 o'clock. You're usually home by 9 at the latest." She asked with concern evident in her voice.

GoGo turned around and gave her a smile."Sorry Honey Lemon, em and Hiro got caught up working on my bike at the lab. He's here to help finish up some schematics." She gestured to him.

"Huh..oh right, right...the schematics." Hiro rubbed the back of his neck.

GoGo just rolled her eyes,"Anyway you want some? I can make enough for three." she gestured to what she was cooking.

"Oh! You're making your hot wings. I'd love some but I already ate sadly. I'm gonna go to bed if you two don't mind." Honey Lemon said.

"We don't mind, you get your beauty sleep." GoGo said

"Night Honey Lemon!" Hiro said as she gave him a hug.

"Night Hiro, night GoGo." Honey Lemon then walked into the hall and into the first door which was her room.

"So hot wings huh? You know that's my favorite and I'm really judgemental on them." Hiro said with a smirk and raised eyebrow.

"Well, I'm sure you'll love mine cause hot wings are also my favorite." GoGo smirked back at him.

About 20 minutes passed and the hot wings were finished and divided onto their plates. GoGo sat Hiro's plate down and sat down across from him. "So, let's see how I did why don't we." She smirked.

Hiro eyed her then the hot wings. He grabbed one and looked it over before taking a nice size bit. After chewing and swallowing it his face grew a huge smile,"These are amazing Go, I'm afraid to say but, they may be better than Aunt Cass'." He proceeded to eat more of the delicious hot wings.

"Wow, that's a lot coming from you Hiro. I'm glad you like them." The both ate in relative comfortable silence enjoying each others company.

After 15 minutes both had finished and Hiro helped wash up. They proceeded to GoGo's room all the way at the end of the hall. Once there she went to her closet and got out her bot's out."So, if you know so much about my time as Tomago the Fighter, let's see if you can name the bot's I used. I only used two." They sat down on her bed as she pulled out one beat up looking bot. It was tall, almost 2 feet, skinny and had a claw on one hand and a saw on the other. He was missing a leg however and his claw was broken.

Hiro's eyes widened,"That's Claw Saw! I remember the story, Yama started tearing at him even after he was down wasn't he?" Hiro said, with slight disgust in his voice.

"Yeah, I wanted to jump him but I didn't thankfully. His gang would have really gotten me." GoGo said. She then pulled out a smaller but fatter bot. This one had claws on both hand but a flamethrower in his chest."I should've used FlameBlast against him. Maybe then I would've stood a better chance and not lost." She said looking at the bot in her hands.

"Well hey, at least some good came out of losing though. You got out of it and joined SFIT, and meet the whole gang." Hiro said trying to cheer her up.

"Yeah that's a good point. Otherwise I would've been on the street if it hadn't been for Honey Lemon." GoGo said, looking at her bot. Memories flooding in about her family. Visibly she kept herself solid but inside she was broken.

Yet somehow Hiro saw this. He saw thru her solid outside and saw the brokenness she housed. He moved over and hugged her, this time she fully accepted it and returned it. Her outside shell cracked and broke and a few tears actually shed. Hiro led her to lay down with him still holding her. They stayed that way for almost 30 minutes when Hiro realized she had fallen asleep on his chest. He glanced at the time that read 11:30, about to move when a yawn racked his body. He decided instead to turn off the lamp next to him and let sleep consume him.

It was now June 2nd, a Tuesday. There was no school for anyway due to school holiday that no one really cared about other than no school. The time read 10:30 a.m. and Hiro and GoGo were still asleep, still with GoGo on his chest with Hiro's arms wrapped around her. Honey Lemon had woken at 9 o'clock and started breakfast at 10 o'clock like she always did on free days in hopes of waking GoGo. Usually it always worked but here it was 10:30 and breakfast was done and no GoGo. She decided to go check on her.

When she reached the end of the hall where her door was she went to knock,"GoGo-" The door creaked open at her touch. She peered in and gasped at what she saw. There, laying still in their clothes from yesterday was Hiro with his arms wrapped around GoGo laying on his chest. She squeaked but quickly covered her mouth, then proceeded to take her phone out and take multiple pictures of the sleeping couple. She left, closing the door fully as she returned to her meal.
