Bit of background information about this fanfiction. This story is set after the events of the movie Big Hero Six. The only things that are different is that Levi was the only one who died in the fire, and Eren is the same age as the rest of the team. There are also some other things that are different, like how I incorporated the titans, but hopefully you'll figure it out as you go.
This is just something I couldn't get out of my head, but here we are, with a semblance of a plot and bits and pieces of ideas. I hope you all come along for the ride.
Eren sprinted up the stairs, barely pausing to say hello to his aunt, Armin right behind him. Disregarding the mess of papers on the floor, he leapt into a black spinny chair and turned on his computer.
"Careful, don't hurt yourself," Armin said, sensors beeping.
The green-eyed boy rolled his eyes. "Calm down, Armin." He turned to poke his robot friend in the arm. "Nothing in my room is going to hurt me."
Except for the various figurines located around his room, which he constantly dropped on himself. But those didn't count.
If Armin could roll his eyes, he probably would have. Eren turned back to his computer and opened up a recent project he had been working on.
"If what Sasha told me is true," he muttered, "then with a couple tweaks here and there, this should work exactly the way I want it to…"
A couple adjustments and Eren ran the simulation. "Yes!" he shouted, kicking his legs out to propel him backwards.
"Eren? What's going on up there?" Hanji peered over the top of the stairs into his room.
"Hey, Aunt Hanji, sorry I was in such a rush, but I finally figured out that problem I was working on!" Eren said excitedly.
"Awesome," Hanji grinned. As a fellow lover of science, she was always interested in what Eren was doing.
"Dinner's ready, so you can tell me all about it."
Eren followed his aunt down the stairs, pausing to glance at a picture of his grumpy brother Levi sitting at the top of his dresser. He smiled sadly. If only Levi could see how he was doing now.
It had been a crazy two weeks after his brother died. He and his new friends from the Shigansokyo Institute of Technology had chased down a supervillain. It turned out it was Bertholdt Fubar, just a regular teenager like Eren. He wanted revenge for his sister's death...and Titan Industries was his target.
Annie Leonhardt was currently trapped in a strange crystalline shell, a byproduct of her time in what Connie called the portal-verse. They had her locked away in a sector of the Institute, for authorized personnel only. Professor Erwin Smith had informed the gang that all her vital signs were in tip-top shape though, so she was definitely alive.
"I've been working on a sort of an upgrade for Armin," Eren explained as he shoved noodles into his mouth. "It'd help him better help the injured, based on their individual chemical readings, blood type etc. Sasha was helping me because she knows more about that stuff, but I think it'll really work."
"That sounds awesome," Hanji grinned. "I guess you're really enjoying school then, huh?"
"Yeah, definitely. I regret not joining earlier," Eren replied sheepishly. He graduated high school at age 15, and the two years afterwards were spent playing video games in his garage and building random robots. He thought that was the height of intellectual activity back then, but boy was he wrong.
"I wish I could get back into a lab," Hanji said wistfully. "It's been too long since I've blown something up."
"You should come with me to the Institute sometime," Eren suggested. "Borrow one of the labs for a day. It'd be good for you."
"I am a busy, busy woman, Eren," Hanji reached across the table to ruffle his hair. "But thanks for the offer, kid, I might take you up on it someday."

"Eren! Over here!"
"Hey guys." Eren slid into the chair tiredly, dropping his backpack next to him.
"Rough class?" Mikasa asked.
"Tell me about it." Eren gratefully accepted the cookie Sasha offered. "I've never had my mind blown like that."
Jean smirked. "Welcome to the Institute. We don't just learn about science...we make science."
"Okay, check out this app I downloaded yesterday!" Sasha exclaimed.
"It was newly released today by Titan Industries," Connie added excitedly.
Jean raised an eyebrow. "Then how'd you get it yesterday?"
Sasha looked confused for a moment, then realized the problem. "Ohhhh I totally forgot to tell you guys! I got an internship at Titan Industries!"
"No way," Eren grinned.
"Nice job," Mikasa smiled.
"What?" Jean slid back in his chair. "You got the internship?"
Sasha smiled awkwardly. "Sorry, Jean, I know you really wanted it but they could only choose one..."
Jean groaned. "Beaten by the Potato Girl again…"
Sasha punched him lightly. "Don't worry, I'll distribute some top secret information, Horse Face."
Jean sighed again, but smiled slightly. "You'd better."
"Don't fear, my plasma-induced friend!" Connie declared dramatically. "I'm sure you'll find someplace that will beg for your thin apple slices."
"I know Aunt Hanji loves them," Eren joked.
"Ha-ha, very funny." Jean rolled his eyes. "Thanks for the support, guys."
"Will it make you feel better if we go back to my place?"
"Um, no. You have dirty underwear lying around."
"Not always! The maid cleans it up."
"I still can't believe you live in a mansion," Sasha muttered.
"It's part of the Springer inheritance."
"And an inheritance," Mikasa added, shaking her head.
"Okay, but Sasha has the cool lab at her house, Mikasa has the gym, Jean has the cool TV, and Eren's got the cafe. If we combined all our houses, we'd have the ultimate living area."
"Wanna fund that?" Jean snorted.
Suddenly, Armin cut in. "Your next class starts in five minutes," he said. "You should hurry."
"Thank God for this robot," Mikasa breathed, grabbing her bag. "Let's go. Sasha, get off your phone."
"Hold on, Mikasa! Someone just commented on one of my photos."
"No. We're going now."
"Hey! Ugh, fine! Gimme my phone back!"
The six of them laughed as they walked up the brick pathway to the entrance of the Institute. They only had one more class, and then Hanji had promised them cupcakes afterwards.
"Eren Jaeger?"
Eren stopped, looking around to see who was calling his name. He looked up to see Professor Erwin Smith, the esteemed founder of the Robotics program.
"Professor Erwin, what can I do for you?"
"May I speak with you and your friends for a moment?"
