No matter what age he is, Hiro always manages to hog all the attention and bask it it. Leaving his older brother slackjawed and mumbling "Unbelievable."

This is my first fanfic for this movie… WHICH I LOVED!

1: A Snarker's Plot.

An evil laugh escaped the younger of the hamada brothers as he rubbed his hands together- which pretty much made him look as if he was intimidating a fly. He stared at the equations, making sure that every. Single. Detail. Was correct. A grin spread across his face. 'This has to be my greatest invention yet.' He picked up a remote latched onto the computer, and without even glancing at it, pressed the button, then looked down at it.

Shock was the only look on his face, he had mean't to turn the number into 18 years, not 18 months. His pupils shrank and he looked horrified as he dropped it to the desk, "Holy mother of kinetic and chemicals." He mumbled and immediately began scooting his swivel chair back- but, unfortunately, the remote dropped down from the edge of the table, and to the floor, pointing at the teen.

He gulped - but before he could run, a pale blue ray of electrical power shot out of it and zapped him, causing him to fall unconscious.

"Hiro!"Tadashi called, annoyance lacing his voice. He swore that his younger brother was the sneakiest of the entire family. He pushed his San Fransokyo hat down on his head. He'd searched the entire house, he wasn't in the kitchen- where he was normally found feeding himself generous amounts of anything with chocolate in or on it. He wasn't in his side of the room- where he'd either be doing his homework, or sketching modifications for his bot-fighting robot.

He wasn't in the living room watching television or sneaking good food to Mochi- the house cat, then be ready to put the blame on the innocent soul when aunt Cass finds the speghetti missing from the fridge.

He wasn't in a bot-fight downtown- Tadashi knew this because he'd sown mini GPS's onto every single one of his younger brother's hoodies. He never went anywhere without one.

And he wasn't- the man was cut off with a high-pitched wail. His eyebrows shot up. That definitely was Hiro's cry. But he wasn't a baby and he didn't wail, he whined. But the older Hamada knew that it was his brother. He shot off to where the sound was coming from- the garage.

He pushed up the garage door, and scoffed. Same old Hiro, never on-ed the lights if he worked. "I swear he's a Dracula sometimes." He mumbled under his breath, then looked towards his brothers computer, left on, so were the touch-screen holograms. His brows furrowed. Strange, was all he could use to even describe it. His brother never wasted his computer battery, leaving it on.

His eyes lit up, Battery! Baymax may have known where his younger brother was, even if he didn't. He grinned and mentally patted himself on the back. "Ow."

The sound of an inflating nursing robot was heard. Along with, "I am programmed to heal the sick and injured, what seems to be the problem, Tadashi?"

Tadashi scratched his head nervously. "I can't find Hiro anywhere."

"Hiro is there." The inflated mechanism replied, pointing a finger to a bundle at his feet. Tadashi frowned and crowched down, Baymax trying to as well, but not being able to considering his marshmallow like stomach. Instead, he just watched.

A wail was heard from the bundle. The man frowned, it wasn't a bundle, it was his brother's hoodie! His eye brows lurched and he gingerly poked it, only to have a tiny hand lurch onto it in a death grip. "Ookay, looks like you're more trouble than not," He mumbled to himself, pushing the red shirt down so that his little brother's face would show. And he had to stress heavily on the little. A pair of large brown eyes- a mop of black hair falling over them- stared up at him, his tiny lips pushed outward into an angry pout once his older brother yanked from his grip and scrambled away.

"You're not fourteen… you're an infant!" He cried, perplexed. Causing a baby Hiro to look at him confused before bursting out crying from the shocking loudness.

2: Really, Really Bad.

Luckily, for memories, Cass had kept all of Hiro's baby clothes, which was a huge relief for Tadashi. And somehow, his marshmallow robot managed to get a stack of clean diapers, which was yet another huge relief for the man.

He paced back and forth all over again and again and again, waving his arms around as if speaking some wild sign language. Baymax had stopped watching him since it confused his camera's, but baby Hiro just sat on his bed, watching curiously as the twenty-one-year-old paced back and forth.

"What am I going to tell aunt Cass when she gets home?!" He asked himself, his pupils shruken. " 'Oh, hi, aunt Cass, Hiro did something with the TV remote that turned him one and a half years old, no biggie.' " He said sarcastically, waving his hands in a casual fashion.

His phone beeped. He slipped it out of his pocket. He groaned as he read who it was : The rest of Big Hero 6. "Great. What am I gonna tell them when they don't see my brother at college tomorow?" He mumbled to himself and answered it. He gulped and looked terrified as they said something on the other side. He glanced at his baby brother. 'This can't be happening,' He thought to himself. 'Please not today.' "Sorry, guys, but Hiro can't make it, he's feeling a bit under the weather. What's the ocassion anyway?" He asked.

"But my sensors indicate that Hiro is fine and healt-" The older Hamada cut the robot off by putting his hand over Baymax's speakers.

"Duuuuude," Fred drawled on the other side of the conversation. "It's Honey Lemon's birthday!"

Tafashi stopped pacing and froze. He could feel the beads of sweat forming on his forehead. He never missed any of his friends' birthdays, but if he left Hiro and went, aunt Cass would come and emand an explanation. Before he could reply- not that he had anything to do besides stammer- the birthday girl cut in,

"Aww, poor Hiro, he must feel terrible. I don't want him to miss out all the fun…not that there's anything fun without you guys. Oh! I know! We could come over and help Baymax make him feel better!" The bubbly girl ended the call before he could protest.

He stared at his cell phone screen, mortified. "This cannot be happening… they are so going to freak."

Baymax blinked, then picked up a baby bottle, warming it with the heaters in his hands, he placed it in Tadashi's hands. "Maybe so, but my vast knowledge tells me that not many humans can resist the face of an adorable infant," He stated the fact.

"Yeah," The man rolled his brown eyes. "Like they won't notice a thing when my brother is thirteen and a half years younger than he's supposed to be."

3: Cuteness Wins It All.

Ring. Ring. Ring. Ri-

"Honey Lemon!" Gogo hissed in annoyance, snapping her gum to empasize.

The blond girl gae them a sheepish smile, hiding her face between her shoulders. "Oops, well, you guys can't blame me for worrying about-" The opening door cut her off.

Tadashi stood there, he looked like he was just about to have a worry attack. "Oh," He said. "Sorry guys, but this is a really bad ti-"

"Where's Hiro? Is he okay? What happened? What's the disease?" The blond pushed past him, swarming him with questions as she surveyed the house, looking for the younger brother. Her pink lips were pushed out in a worry pout and her green eyes scanned the area. She heard a depressed sniffle from the above floor. Along with the robotic voice of Baymax saying 'There there.'

She quickly ascended the steps. "Don't go up there!" The older man called desperately as he practically ran up after her, blocking her path with outstretched arms. The green-eyes girl frowned and glared at him. She shook her head.

"What is with you today, Tadashi? Its like you don't want me to help Hiro at all!" She cried.

He glanced away from her, gulping. "Which was pretty much the whole point." He sang under his breath.

With a huff, the birthday girl tried to look over his shoulder, but he kept leaning so she couldn't see.

"So how old are you now?" He asked, desperately gripping at lose ends to find a distraction.

"Eighteen years, four hours, thirteen minutes and five,…twelve…twenty four seconds- make that thirty." She said, before ducking under his arm quick enough.

"No!" She heard him call.

She looked around… there was no sign of the fifteen year old. A hand popped up, and an excited gurgle. She looked own and swore that she was going to die of cuteness. She squealed, clasping her hands together. "Aww, you're so adorable, little guy, what's your name?"

Large exited brown eyes looked back up at her through a mop of unruly black hair. Baby Hiro looked confused for a second, before eruptiong into giggles, waving his arms out to her, demanding to be carried, and being the girl she was, Honey Lemon just couldn't resist. She happily lifted the boy into her arms, and he immediately buried his face in the crook of her neck, tiny arms wrapped around her shoulders in a hug.

Tadashi just stared, slack-jawed as his baby brother purposely buried his face in the blond girl's hair, a dreamy haze just to fool around with him. He looked as if he was in heaven.

"So, Tadashi…" The blond started, facing him with a suspicious look. "You never did tell me, where's Hiro?"

The man could only point a finger, still slack-jawed at the kid in her arms.

"Don't be ridiculous! It can't be unless he accidentally zapped himself …and…" The blond looked at the kid who's head was resting on her shoulder, giving her an innocent looking grin, complete with puppy dog eyes. "Aww!"

That was not the reaction he thought would come. "Unbelievable …" he mumbled to himself.
