I don't own Marvel or BNHA

Somewhere in the seedy underbelly of the Land of the Rising Sun (A slum in Japan)

Wade 'Deadpool' Wilson wasn't the best teacher or mentor Himiko Toga thought to herself as she dumped a bucket of cold water on the man's head.

It had been a month since she had met him, and while he was perfectly ok with teaching a ten year old how to wield weapons, he wasn't the hero she first thought he was. Maybe the swearing should have clued her in when they first met, or the killing his opponent thing, or the desecrating the body with urine thing.

All said and done, Wade Wilson was a mercenary, a highly skilled mercenary with a severe lack of moral compass that allowed him to teach a young girl about all things pointy, stabby, slashy, stealthy, shooty, and boomy. He was also more than happy to kill criminals and let her have the blood, preventing her from going off the deep end like he had.

Seriously, if sanity and Wade Wilson met, sanity would run away screaming as Wade followed in a food truck trying to make roadkill to serve to happy and unsuspecting customers.

As the man sputtered and leapt to his feet, Himiko was already light enough on her own feet to dodge the knife swing that preemptively came whenever Wade woke up.

"Good morning my cute little apprentice, ready to tackle the day!" Wade chirped like he hadn't just tried to gut her with the machete he kept under his pillow.

"Yup, and I made breakfast again, because you are still forbidden from cooking." It wasn't that the red suited man couldn't cook, it was more that she didn't want the police coming around again because Wade filled a warehouse with pancakes he had cooked for breakfast with ingredients he had taken without paying for….for a fifth time.

"It better not be undercooked sausages again, or those little fish. Makes me feel like I'm eating a dick for breakfast."

"It's buttered toast and a jar of peanut butter today, no edible dicks until you least expect it!" Himiko responded with a giggle, skipping out of the room amidst the merc's shouted protests.

"Mmmmmm, nut butter." Was all Wade had to say as he ate most of a jar of said butter on a single piece of toast.

As the duo ate, the day's planning went a little something like this. Wade pitches an idea, Himiko says no. Himiko pitches an idea, Wade calls it boring. The two glare at each other, which turns into throwing leftover bits of breakfast at each other, then throwing silverware, then the two finding their way to the floor of the empty warehouse they stayed in in a full sparring match, complete with knives, swords, and the occasional gun. They had yet to delve into the mass amounts of explosives Wade had stashed around, but it was probably only a matter of time.

After Wade stopped trying to kill Toga and Toga stopped stabbing Wade, it was time for lunch and trying to find jobs that fit both of their criteria. Which for Wade meant a lot of money, and for Himiko meant hunting down the bad guys. Both agreed the jobs should have ample amounts of violence.

So far they were being hired by both sides of a yakuza gang war to off members of the other side. Only Himiko's ability to transform into offed gang bangers kept both sides from realizing they were just paying the merc and his apprentice to off themselves one at a time. It was work they could both enjoy. Protecting innocents like a hero and killing for money like a mercenary.

Of course, there was only so much work like this available at a time, criminals rarely paid to have other killed and governments just passed the work onto the heroes they already paid to fix their problems. After today's job, which would involve finishing off one of the two feuding yak herds, work would probably be rather scarce. Which meant Wade would keep on traveling his golden road, and Himiko wasn't sure if she was going to follow.

After the quick breakfast followed by knife fight, in which Wade managed not to get stabbed in his bits or face like Himiko had been aiming for and Himiko worked on her vanishing stealth technique to prevent Wade from stabbing her back, the duo set off to clean up the yaks, the fact that Wade was attempting to read a book in Nepali about yak herding as the two entered the subway drew the merc more strange looks than the fact that he was in a full red bodysuit and was traveling with a young girl in a school uniform and was carrying a large duffle bag with mysterious red stains. When the duo finally arrived at the laundromat that was the front for the yak base, Deadpool finally gave up on his book and Toga drank a water bottle of blood that they had 'acquired' from the last yak they had found from this particular gang.

"Ok, here's the plan, we do get help." Wade said as he strapped his weapons to himself in the front parking lot. Himiko was only glad they weren't any pedestrians to call the heroes on them, for a professional, Wade's dictionary seemed to not include words like subtle, or any synonym applicable really. As bloodthirsty as she was, she knew better than to walk around in the open with weapons revealed.

"Ok, we do get help." Toga agreed in the yak's body, already knowing how she was going to make the play, glad for once her transformation had a mutation quirk that made him a walking wall of muscle that Wade had mocked relentlessly for having a small dick. A fact Himiko could now confirm in his body.

Which brought along the idea of using her special vial to find out just how big her Izu was, blushing intensely at the thought. She wouldn't of course, but as she was almost 13 and only growing older, the idea seemed more and more appealing. She let the thought linger in her mind as he increased mass formed over the bodysuit she wore under her casual wear stolen uniform and tore the clothing off the form of the large yak she was pretending to be, exposing the little fish to Wade, who cackled at being right. Throwing on a larger set of slightly bloodstained clothing and arming herself with sharp objects and other fun toys, Himiko was ready to go, with the thought of Izu still in the front of her mind.

"Ignoring the yandere blush and smile on the sausage and fish sized man, let's roll out!"

The duo entered the shop, leaning on each other, but before Wade could speak, Himiko stole his line.

"Help, get help, it's my friend, he's suffering from severe groin fungal growth and needs something to sterilize the area!"

"Jailbait says what n-!" Before Wade could finish his retort or the security yaks could react, Himiko used her quirk transformed and enlarged muscles to chuck her mentor like a log at them, sending them all over the counter, where Wade quickly snapped the two yak's necks.

"That is NOT how get help is supposed to go, I'm supposed to be the big dashing hero and you're the damsel in distress. And fungus, I'll have you know that despite my skin condition, my penis is fully functioning and STD free. If it weren't pedophilia I'd offer to show, but that crosses a line I will not cross. I'll leave the yaks to do the little girls. Is that considered beastiality too…?"

Rolling her eyes at his crude overdramatics, Toga prepared for the next step of the plan, getting to the hidden elevators in the back room. The two entered the backroom with pep in their step and made it through the empty room with Wade only tripping once.

"Now remember my cute little vampire, when fighting the mighty Yak, one must always keep in mind two things, the horns they have on their heads with which to gore you, and the fur on their back that we can shave off to make blankets and sweaters." Wade lectured as they entered the elevator and hit the lowest level button.

"Got it, dodge bullets and knives, steal all their gear, and blood, can't forget that." Himiko replied with a nod, "And what about the thing those 8 pickle guys wanted us to grab for them while we were in here.

"Oh right, Cheese said something about that." Deadpool mused as the elevator music softly played as the elevator moved down slowly to the obscenely deep basement. "I'll leave you to grab the techy-techy stuff then while I make a mess."

Himiko just nodded and smiled again, ready to skip off into the yak base and throw her throwing knives. The elevator finally reached their intended floor and Wade gave off a warcry that was incredibly insulting to those of Native-American descent as he charged off down the hallway, katana in one hand and extended clip uzi in the other, firing at any yak that poked up from their grazing.

Himiko followed until she reached the first fork in the path, and took the one that lacked the bullet holes in the walls and yaks. Which made this the path Captain Deadpool did not go down.

And of course, Wade being Wade, he took the wrong path and wound up at the science labs, which was evident by Toga walking right into the boss yak's big assembly room with most of the yak running around to try and find a way to stop the crazed fungal infected man now running through their base.

"Mako, where have you been? Doesn't matter, go kill that crazy bastard merc, he backstabbed us!" The boss yak with arrow shaped hair yelled at her. Himiko honestly didn't remember his name, started with a W maybe?

Ignoring him, Himiko went to the largest grouping of yaks and reverse pickpocketed one of them before quickly moving away. Not the most subtle thing in the world, but when handling explosives, subtle tended not to work.

The live grenade she had stolen when Wade was staring at her exploded, but Himiko had miscalculated slightly, instead of a normal explosion, it was one Wade had tampered with. Meaning the explosion was both pink, and larger than intended. The coloration wasn't a problem, the increased size however, was.

Contrary to what Wade preached, bigger was not always better as it turned out. She'd be sure to tell him that later.

"A little girl, really, that's who's been tearing my operation apart!" The boss yak yelled as the explosion did enough damage to Himiko's transformation to make it slide off her, revealing her true form underneath, dressed in the red and purple jumpsuit Wade had 'acquired' for her. Whatever it was made of let her not be naked when her quirk wore off. Wade just called it superhero clothing and they both went with it.

"Well don't just stand there, shred the bitch!" He yelled as the other yaks shook off their surprise and began firing their guns at her. Himiko was quick to leap to her feet, shaking the last of the gray matter that formed her disguise and strafed across the room, whipping out several large sharp objects from their holsters on her suit, but sadly the majority of her arsenal was left behind in her transformation goo. Even if she had those extra stabby implements, it probably wouldn't be enough. Wading into groups of gunmen was Wade's work, not her's.

Despite not quite being a teenager yet, Himiko managed to dodge most of the bullets, only a few of them scraping gouges across her suit, leaving bloody trails in their wake. Her training with her mentor merc the only reason she hadn't been turned to swiss cheese but the armed yaks. She had to hand it to the boss yak though, he had managed to take a group of people with absolutely no combat ability through their quirks and make them effective enough to have an organization.

She landed from a jump and quickly took off again, this time holding her breath and clearing her mind, going into super stealth mode, vanishing to the senses of most of the yaks around her.

Unfortunately, her technique wasn't perfect, and the boss yak managed to land a clean shot to her ribs with the longer of his two oddly shaped extendable locks of hair. Although, it lashing out blindly as she was landing behind him made her think it was less her ability that was the problem, but rather the man's quirk gave him something along the lines of precognition.

"Gotcha bitch." The lead yak growled as his men recovered from her vanishing act, watching as Himiko began landing in slow motion. "I am the great Chronostasis, I will not be defeated by a child and a red suited idiot." The boss yak growled, his grey arrow hair whipping about as Hiiko finally landed, panic beginning to well up in her gut.

The wound wasn't too bad. A clean puncture, and the slow motion she was moving in meant that she wasn't in danger of bleeding out just yet. The yaks with guns pointing at her while she couldn't dodge however, was a much larger problem.

It was like the tint of insanity that Wade carried around him was stripped away and Himiko finally realized how deep she was in shit. Alone, outnumbered, out gunned, and crippled. She was completely at the mercy of professional thugs, ones that leached off of society to exist and would have no second thoughts about doing horrible things to her and others. People who weren't twisted by their quirks like she was, but people who WANTED to hurt others, who ENJOYED making others despair.

"We are going to make you suffer bitch, the yakuza will rise again…" And there it was, the monologue, commonly used by overconfident villains and allowed for heroes to pull a win out of their asses. And in this case, maybe but her enough time for Deadpool to get here, and at least for this stupid slow motion to wear off. Her usual plan of run around and dodge while throwing enough pointy weapons to make shish-kabobs for an army wasn't an option with her slowed movement and lack of excess throwing knives, and plan B of 'let Wade handle it' was also out, as Wade was probably tearing through the science labs looking for the boss guy, and probably wouldn't realize he had taken the wrong hallway for another twenty minutes.

Those were really her only two plans, maybe coming up with a few more options would help her in her vigilante career, or at least keep her from winding up in a situation like this again. If she survived this that is.

While the boss was still monologuing, Himiko felt the blood spilling from the bullet scrapes and hair stab wound begin to flow normally again, exactly sixty seconds after she had first been struck. A time limit. Not that it really mattered, not when she was this out gunned. But if she was going to go out, she was going to go out with a bang, and feeling as close to one of the few people who believed in her as a person as she could.

Before the yakuza could react, Himiko grabbed the vial she had worn as a necklace since she had last seen her Izu and chugged its contents, drawing her last two knives from her waist as she felt the grey goo of her transformation covering her. She only had a brief moment of clarity in Izu's body before she saw the yakuza unload at her, and a deafening roar fill her ears, before everything went black.

Her quirk, the one that made her crave blood since she had first awakened, was an interesting one. It required the blood, the DNA, of the person she wanted to transform into, and would transform her into that person as they naturally were in that moment. The few times she had used Wade's blood to transform into him, she instead turned into him before the horrific scars covered most of his body. So when she drank Izuku's blood, she took on the form of the boy as he was when he was ten, when he had given her the vial.

One thing she wasn't aware of though, was that her quirk also copied physical quirks. The yakuza who she had walked in as, had an enlarged muscle quirk, so when she transformed into him, her transformation had his quirk swollen muscles. If she were to transform into someone with extra arms as their quirk, she too would have extra arms to wield. So when she transformed into someone who physiology allowed their inner darkness to manifest into a singular personality, containing most of that person's negative traits, all of her own negative features took on a life of their own.

Himiko's quirk born bloodthirst, her anger at her parents and society for forcing her away, at the quirk hospital for never really trying to help her, her frustration with once again being helpless at the hands of others, even the her freshly developing lust for the one person who believed in her. They all coalesced into a single mind when she drank Izuku's blood. And when she stood in his form, his young body that was unable to hold back the powerful personality that had just rapidly developed in her mind, and was perfectly suited for allowing that monster to be set free. It took less than a second for it to break free, and throw Himiko from the driver's seat of her own body.

In that moment, all of her anger, her insanity, and her passion ran free. And the poor poor yaks that had crossed her felt every bit of that power as it rampaged through the room, red skin glinting in the low lit room as Chronostasis himself was flung about like a ragdoll.

It only lasted a few minutes, the amount of blood she had consumed wasn't enough for her to transform long at this level of power, and when the time ran out, the raging monster melted away into her grey transformation goo, once again trapped away in her mind, but unable to be set free. Himiko's body just wasn't built to set her free like Izuku's was.

And with all the gathered yakuza knocked out or worse, Himiko managed to take in the sight for a brief moment before she slipped into blissful unconsciousness, not yet aware of her head's new denizen. And that was where her mentor found her, surronded by the bloodied bodies of her enemies and a peaceful smile on her unconscious face. Because even if she wasn't fully aware of how she did it, she knew she had beaten the bad guys, she had taken her first step as a hero, just like her Izu always said she could. And for her, that was enough.

But one thing both her and Wade missed as he carried his cute little student out of the building, was that Chronostasis wasn't as finished as they thought he was. He crawled out of the remains of his base, dragging his two broken legs behind him as he went. He didn't care if it meant he had to work for Kai Chissaki, he was going to get his revenge on the little girl who broke him, the red skinned berserker that hid under the surface wouldn't catch him by surprise again.

Originally, this was only going to be the first half of a chapter, the other half taking the timeline right up to before canon, but I figured with how long this got, it could stand alone as its own chapter. I hope I did Deadpool right, he was really the only character who fit mentally and skill wise to be Himiko's mentor, and he also gave me a Weapon X tie in for later, which is a hint for the one student change I plan on making to the Class 1-A roster. Hint hint nudge nudge.

As for Himiko's quirk, manga spoilers ahead you have been warned, that she can use the quirks of those she turns into is awesome, but the only one we have confirmed at this point is her using Uraraka's quirk, which is based on the physical change to her hands, the cat's paw like pads on her fingers. So going off this theory, she could copy quirks like Kyoka and Shoji, but not those like Todoroki. One grey area would be someone like Bakugo, whose quirk is an emitter, but has physical causation, his nitroglycerin sweat. I would lean towards yes she could use it, but I could be wrong.

I took that physical change thought and added Izuku to it. Physically, Izuku did generate a second personality based on his more primal instincts, and his body is capable of setting that personality loose in its own form. For Toga, when she first drank the blood, she developed her own primal personality, but unlike Izuku, it can only come out when she transforms into Izuku because her own body lacks the capability to do so. Yes, I made her Red She-hulk, although I'm going to come up with a different name, that's what she physically appears as. The only other transformation I was considering for her was into Jailbait, who is a very minor gamma character from some offshoot series, but as much as it fits Deadpool's nickname for her, it's a little too obscure for me. Red She-hulk should at least be more recognizable because Red-hulk himself is more well known.

I hope everyone is doing well, and while I don't usually use my writing as a way to send messages, now is a time I feel I have to. Everything that is happening in the US right now, the protests, they are happening for a good reason. This is a message that needs to be spread and an issue that had carried on for way too long. Black Lives Matter.
