Um...so.
I found few (dozen) yandere!Tadashi fics (and pics) and this happened.
Our favorite adorkable genius is kinda...off. And he's not gonna let a little thing like death keep him from the object of his desires. No one can have Hiro but him. Various interpretations of their relationship can make this even more or less creepy than it is.
Wildly diverges from canon after the fire. Sort of. The title is from the Shinedown song of the same name.
*SYHM*
Baymax's first encounter with Hiro is when the boy is unconscious. Draped across his creator's arms as if fragile. The robot awaits instruction having not yet been programed to automatically initiate inquiry into his patient's status.
"Baymax, scan him." The tone suggests agitation and increased stress levels. But at the time, Tadashi wasn't his patient. His unresponsive brother was.
"Scan in progress." He complied. "Scan complete. The patient has multiple contusions and shallow lacerations about the arms, wrists and ankles. A bruise 30 by 19 cm is quickly forming along his lower lumbar region. Diagnosis: blunt force trauma as primary cause of injury. Cause of lacerations unknown. Recommendation: application of antimicrobial spray and avoidance of pressure on bruised areas."
"No broken bones or internal injuries? No head trauma? Nothing else?" The stress levels plummeted.
"An older injury along the patient's left hip and thigh resulted in a peculiar scar. It appears to be lettering. However the scar is consistent with deliberate cutting of the flesh as opposed to burning. Likely cause, a form of abuse."
The stress levels spiked briefly before settling again.
"Baymax, the cause is NOT abuse." He snapped. "Administer a mild sedative."
"The patient is already unconscious-"
"Do as I say."
The large vinyl android compiled once again; gingerly injecting the prone boy with a dose of midazolam . He turned his head to observe his .5mg dissolved in sodium chloride. Then observes his creator carefully lying his patient on the bed and removing the outer layers of clothing before setting about cleaning and dressing his wounds. As Tadashi worked, Baymax's scanner once again went over the patient, per his monitoring protocols. The sedative prevented the patient's reaction to what should have been painful movements of such activity.
Once again, the older injury was noticed by the bot who matched it to Japanese characters it encountered often. They translated loosely to loyal/faithful and just. Their configuration suggested a name. Hiro was young but human body art norms varied from culture to culture. Nor was his creator alarmed by its presence. Baymax promptly disregarded it.
"Watch him. Closely monitor respiration, heart rate and blood pressure and respond accordingly without alerting paramedics." Tadashi ordered then grabbed his coat, hat and satchel which swung into Baymax's range. The robot breifly detected various surgical instruments inside.
Without further instructions, Tadashi exited through the window. A moment later, his moped could be heard turning over.
So began a vigil lasting 3 hours. By then Tadashi returned the same way he had left.
"Is he alright?"
"The patient has had no change." Baymax 'blinked' as his scanner activated without prompting. "I have detected traces of blood but not the source. Where are you injured Tadashi?"
"Mm? It's not mine." He murmurs, crawling into the bed with Hiro and tucking the sleeping boy close. He is soon tracing the scar on Hiro's hip. Baymax observes rust colored residue on some of his cuticles along with fading adrenal hormone as he does. He logs the phenomena in his data bank as a possible treatment for stress or depression as that the activity increases Tadashi's serotonin production.
It does not occur to the droid to inquire whose blood it is.
Tadashi himself thought about the 4 idiots he'd just dealt with. The brainless bastards jumped Hiro after his creation wiped the floor with their expensively upgraded bot. Beating him unconscious and daring to mar his perfect skin. One even had the nerve to stomp his back before roughly binding the limp child's hands and feet with worn and abrasive twine. Intending to sell his pretty sibling to 'recoup the loss of their prized bot'.
No matter. They weren't in a position to try it again. Ever. Hiro was entitled to his fun after all. His scolding of bot fights done mostly to appease social norms. And his aunt.
Besides, with carefully attention, there'd hardly be any scars to remind the brothers of the incident. The younger would notice the news report whenever the bodies were found. So smart, he picked up on things like that no matter how obscurely mentioned. Even if Sanfransokyo's finest couldn't make the connection. He also knew how much his oniisan loved him. That he'd keep him from anyone meaning harm.
Sore losers itching to settle the score.
That old hag that was always touching him in high school. Even when he moved away from her.
Not to mention that cafe regular with all that rope, duct tape and those sick dvds in his trunk. Kept trying to get Hiro alone...
He took care of them all. Hiro would wake up sore and and confused, asking what happened. And Tadashi would assure him everything was fine. Like every time before.
"I'll always be there for you. Always protect you otouto. You belong to me an me alone. No one else deserves you." The elder whispers as he drifts off to sleep.
*SYHM*
Hiro and his new friends figure out someone was responsible for the fire but part way through their preparations, the neurotransmitter returns to Hiro's desk. They are even more confused when professor Callahan is arrested for arson and murder. THAT comes completely out of left field.
The man confesses that he set the fire to steal HIro's project. That he knew Tadashi Hamada ran in, heard the younger man calling for him, saw him in danger. But still used his brother's microbots to protect only himself from the explosion. With this revelation, Hiro can't help but feel angry at himself. Even though Callahan started the fire, his invention killed Tadashi. It was all his fault.
Why? Why did any of it happen?! How could someone betray a person who admired and trusted them that way?! So cold and callously?!
Hiro lay on his bed sobbing. He didn't have the energy to do much of anything for the last few days. All he can do is brood over the situation. He feels so alone.
/I'll always be there for you. I'll always protect you otouto./
Why...
Why did Tadashi lie to him?
/I've never lied to you Hiro. And I never will./
*SYHM*
The trial should have been an open and shut deal. A confession, especially one with such detail only previously known to authorities, usually stands as enough to convict. So of course that weasel backtracked and lawyered up so fast the DA's head spun. Temporary insanity as his defense. He was ready with doctors to testify that his mental state at the time was most likely compromised. The grief over his daughter's loss having finally come to a head, he was gripped by psychosis and irrational behavior. And as the cause of her loss, Krei was guilty of arson and murder by proxy. So what should have been a matter of filing paperwork to reserve a cell for him at Sanfransokyo Federal Prison, became a media circus.
Naturally as the cause of 'the fall of some of the greatest minds in two generations' the Hamadas gained a fair amount of attention. Some of it great. Some not so much. Some downright terrifying. Not everyone believed one or both of the men was capable of what had been charged. Theories ranged from Hiro being some sort of attention seeking delinquent (his record so not helping his case) to his older brother having a fatal attraction to his professor. The fire having been an 'if I can't have you nobody can' type deal that backfired. Pun intended depending on who you asked.
So many reporters and rubberneckers showed up believing whatever version of events, the Lucky Cat Cafe temporarily closed. It got the the point that the Hamadas couldn't even leave without a police escort. Gogo, Wasabi, Honey Lemon and Fred all had to sneak in just to check on the small family.
"Man, those guys are like piranha." Gogo slid down the wall once she got into the household proper. The living space above the cafe. "I can't believe that jerk!"
"The guy left Dashi to burn so he could steal his brother's project." Fred's happy go lucky tone was uncharacteristically hard. "Of course he's got no problem throwing the Hamada's under the bus just to get out of punishment. All the lies he's been spreading."
"I just wish I could get Hiro out of his room. He only comes out to eat and that's so rare as it is." Cass sighed setting down a tray of hot green tea, cinnamon crackers and sweet bean jelly for her guests. "But then I'd have to have a way of getting him out of the house..."
CRASH!
Everyone ran down the hall at the sound of glass shattering. Cass's heart clenched as she realized it had come from the room the boys used to share. She could see Hiro lying on the bed for just a second then the door slammed shut.
Then the screaming started.
"Hiro! Oh god!" She frantically tried to open the door, but the knob only twisted uselessly. Like someone was holding the wood firm from the other side. The sound of more glass shattering and things being knocked over causing her fear to grow. She furiously banged on the obstacle. "Hiro! Sweety!"
"Lemme try somethin." Wasabi moved her back before attempting to ram it. Reasonably big guy plus momentum should equal broken door. He backed up then ran full speed at it, focusing all the potential force on his left shoulder.
WHAM! CRACK!
"Oh my gosh!" Honey Lemon gasped darting to him. The laser tech crumpled to the ground howling in pain. His limp arm and the undamaged door confirmed the sickening crack to have been bones not wood breaking.
The screaming grew louder. Gogo had bolted down the stairs the second the bumping and thudding started to try and get the help of one of the officers assigned to the house. She might not have registered that the noises from inside didn't sound like a young boy, but a grown man.
"Please...stop..." A grown man indeed. His voice colored by a wet gurgling noise.
"Why should I? You can't keep your filthy hands to yourself."
Everyone paused, even with as much pain as Wasabi happened to be in. That second voice they knew very well. That second voice shouldn't be possible. It belonged to a dead man. The loud crunch followed by sudden silence only served to compound their fear.
The door finally opened, you could hear a pin drop. Hiro still lay on the bed wide sound asleep. Mochi purring sleepily on his headboard. Near the window, glass and wood splinters littered the floor. Among the debris, lay a man dressed head to toe in dark blue, wearing a ski mask. Blood pouring from his mouth. Arms, hands and fingers bent at unnatural angles. His chest wasn't rising in the slightest either.
Baymax had activated but the nursebot's attention wasn't on the bloody mess but on the bed. Sheets and blanket haphazardly strewn about suggesting he had been sleeping but startled into consciousness by the flopped back over dead to the world. That and the fact only an oversize t-shirt and a pair of briefs covered him. Hiro was too shy about his body to sleep so exposed.
"Holy shit! Wh-what happened?" Fred exclaimed. "Geh?!"
"Y-you guys see that too right?" Honey gulped.
"Tadashi is here." Baymax stated. Like it was normal for the departed to return.
"I know..." a soft coo escaping Hiro, illogically not waking as another shape on the bed pulled him nearer.
Cass paused mid stride to check on Hiro. She must have been going crazy but the others saw it too if their frightened shouts were any indicator. Even the giant marshmallow man acknowledged the presence. Lying next to Hiro was Tadashi. Or something that looked like her dead nephew. A pale hand stroked his hair before sliding down the boys flank. Eventually settling below the waist, gently tracing a mark on Hiro's bare thigh.
"Tadashi?" she whispered.
"Yes Aunt Cass?" For an apparition, it appeared quite solid. It's body making a depression in the mattress. Ruffling Hiro's hair and clothes with it's hand. Said hand casting a shadow.
Yes it. This thing wasn't Tadashi. No, it had to be a demon that stole his face, an obake. Her obaasan had told her of such things as a child. Mischievous, often malevolent creatures that took on other forms, often of the dead to confuse and trick the living. She instantly regarded such stories as superstitious chatter from the older generation. Which she dutifully listened to out of respect.
The mark it seem so fascinated by was visible in glimpses during it's ministrations. The instant she saw it, clearly saw it, she felt sick at the realization: it was Tadashi's name. Tadashi has cut his NAME into his baby brother's flesh YEARS before he died. The kanji 'strokes' of scar tissue too detailed, too neat and carefully done to be Hiro's work. Especially at such an angle.
Kami-sama...what else had he done to him when she wasn't looking?!
"No...no! Let him go! Hiro get away from that thing it's not Tadashi!" When all he did was move closer to his not-brother in his sleep, she lunge forward to snatch the child from the monster's grip. At the edge of the bed, she encountered some sort of invisible wall. For a moment it frowned at her. Deep amber eyes flickering to blood red a few seconds.
"You can't take him from me. He 's mine." It glared.
That confirmed it for her. Tadashi would never say something like that. But then...he also wouldn't brand the child either. How well did she really know her late nephew? Could he have been so obsessed with his otouto that his spirit became attached to him after death somehow? Obaasan also told her about ghosts that remain with their families as protectors too. The state of the man on the floor suggested he had been one of the yahoos who had threatened their lives after this madness began. But such spirits...they weren't...homicidal.
Right? The stories were a bit vague in her memory.
"Dashi...did you really do this?" Fred gulped. Gogo had returned with two cops who had no idea the scene in that room. Wasn't like anyone else did either.
"Of course. I promised to protect him. To never leave him. And I never will." The trademark goofy grin they all remembered warping into an eerie parody of itself. "We'll be together forever."
*SYHM*
Okay. So i went with Tadashi having a fair bit of medical know how to be able to program Baymax. Complete with his own surgical kit and various drugs. Things no one without proper licensure should have legal access to. It's also worth mentioning that midazolam is used during short medical procedures on kids. It's an instant KO and the child often has little to no memory of the procedure and some time leading up to it. Though they should be closely monitored when dosed.
Obake are shape shifting yokai. May have stretched their actual purpose for the story a bit.
So, whatcha think? Reviews are like hugs! Sirensoundwave out.
