AHOY TATERS! Welcome to my new story. This one was inspired by several fanfics I've read, such as Invincible by Avatar Conner, The Green Devil by Ghouldash97 and a Wattpad story about yandere My Hero academia girls!

In this story, Ben Tennyson goes to a universe that is a fusion between Invincible and My Hero Academia. Where several women will become yanderes for him!

Here are my plans for who will be in Ben's yandere harem!

Yandere Reiko Yanagi

Yandere Itsuka kendo

Yandere Kinoko komori

Yandere Ibara Shiozaki

Yandere Yui Kodai

Yandere Pony Tsunotori.

Yandere Setsuna Tokage

Yandere Pixie bob

Yandere Mandalay

Yandere MT Lady

Yandere Female monoma

Yandere female invincible

Yandere Midnight

That's what I've got so far!

Now onto the story!

Ben Tennyson, the king of heroes, he hasn't even started High school and he's already saved the Earth from alien invasions, Eldritch nightmares like Diagon and traitorous heroes such as his former idol Captain Nemesis.

On the cusp of entering High school, the Omnitrix wielder was about to be sent off on a quest to enroll in a High school like none existed on his Earth.

While at that High school, all his female classmates will develop an unhealthy obsession with him.

Ben Tennyson will not only have to survive the villains of this new world, but his own female classmates who want nothing more then to jump his bones.

And so the story of a Ben Tennyson with a yandere harem begins.

{BREAK}

A brunette Caucasian boy let out a pained groan as he opened his acid green eyes with all the slowness of a rusted door, he flinched at the sudden headache that assailed him. His drowsiness and pain slowly began to turn to panic as when he tried to rub his forehead he instead felt the sensation of warm and coarse rope digging into his wrists.

"What the- why am I tied up?" Groaned the greatest hero, quickly feeling how his wrists burned from the tightness of the rope, how his fingers had gone numb, along with the sensation of a cold floor underneath him.

When he finally came too, the king of heroes saw that he was in what looked like a bank vault. He found himself surrounded by bars of gold and crates full of money, though it obviously wasn't American money.

The king of heroes became alert as he saw that he wasn't the only one tied up, he counted ten other people in the vault with him who were also tied up.

'Hmm, why am I the only white person here? Did I wake up in China town?' wondered Ben Tennyson.

The smell of sewage mixed with decay made Ben gag as a groan like an old man giving a death rattle made his ears itch. Into the vault stepped what looked like people who had been cut open, disemboweled and then sewn up together again.

It was obvious they were some form of zombie, with how their bodies were pale as chalk and crawled with flies and maggots. The zombies were grabbing bars of gold and crates of money.

"I'm glad to see you're awake." The voice of a girl, demure yet relieved, made Ben turn to look at one of his fellow hostages. The girl was Asian, and clothed in an ankle length skirt and button up blouse.

What was most noticeable about her was the fact that her hair was made of thorny vines.

The girl looked at him with a reverence that Ben had seen on many fangirls. "Who are you? Where am I?" He asked in a hushed whisper.

The vine haired girl's look of concern got more intense. "You don't know where you are? Oh you poor lost lamb. We're hostages in a bank robbery being conducted by a sinful plague doctor villain."

Ben found her voice serene, as if she was a member of a church choir. Nonetheless Ben had a few more questions on his mind.

"What city are we in? And again, who are you?"

The vine haired girl blushed as she avoided looking at Ben. "I am Ibara Shiozaki, and we're in the city of Musutafu in Japan."

Ben's eyes widened. ' I'm in Japan? How did I-'

A blurry flashback raced through his brain, seeing a silhouette wearing a lab coat and carrying a pocket watch standing in front of a blue portal. Ben's acid green eyes widened. 'Professor Paradox! He sent me to another universe!'

"Ibara, can you use your vines to cut me free?" He whispered, "I can take out these zombies and stop the robbery!"

Ibara's blush intensified. ' He just called me by my first name. He, an angel, is on a first name basis with me.'

Ibara was conflicted, she wanted to help this angel that had the misfortune of falling to Earth in a bank robbery, but there was a problem.

"If I cut you free and you fight the villain, you'll be arrested for unauthorized quirk usage."

Ben raised an eyebrow. "Why would I be arrested for defending myself? And what's a quirk?"

Ibara's concern became deafening to Ben, as tears began to leak out of her eyes. "Oh you poor angel, what did that monster do to you?"

Ben felt guilt grab his heart and he frantically shook his head. "Please don't cry! I'm fine I promise! There's nothing wrong with me!"

"Yet you don't know what a quirk is… when eighty percent of the population have them."

Ben connected the dots as he looked at Ibara's vines. ' Her hairthat must be a quirk. Quirks are a form of superpowers!'

Before the conversation could be continued, a sound like cans of food tapping against the floor, made the king of heroes look up to see a strangely dressed plague doctor in front of him.

The first thing Ben noticed was the villain's bronze armor and bronze cape. The second thing he noticed was that the villain's face looked like a plague doctor mask made out of bone and that his hands looked like black leather gloves.

PRESENT MIC'S VOICE: Presenting The Bronze Kneecap! A villain with a suit of armor created from his third place trophies! His quirk is Plague Doctor! He can kill any human with a single touch and perform surgery that reanimates them as a zombie!

"Hello gaijin shonen." The villain's voice was like Elon musk if it was combined with an echo. "It's unfortunate that an innocent child like yourself was at this bank when I began my robbery. But alas I can't just let you go, not without using you as a hostage first."

The bronze plague doctor-like villain grabbed Ben by the scruff of his shirt and began dragging him out of the vault, much to Ibara's panic.

"You sinner! Let that angel go!" Shouted the vine haired girl as she struggled to stand on her tied up feet, only to fall down.

' Did she just call me an angel?' wondered The brunette in confusion. His confusion turned to frustration as his wrists still bound behind his back prevented him from reaching his Omnitrix.

He soon found himself in the main lobby of the bank, which was missing it's roof as if it's roof had been ripped away, while it's left wall had been smashed. The King Of heroes soon saw why, as he immediately spotted an Asian woman that was taller then most houses. The Asian woman possessing long blonde hair and a skin tight purple and tan costume.

To his concern, the giant woman had blood flowing from her forehead as a group of seven zombies had her pinned to the floor while assaulting her with various powers.

The sound of gunfire made Ben's ears ring as in front of the destroyed bank, were a squad of police officers emptying their ammunition into more zombies.

"You poor fools, listen here!" Declared The Bronze Kneecap as he tossed Ben in front of the injured giantess.

Out of the villain's left knee, emerged a bronze three fingered fist with spikes on its knuckles, which he aimed at Ben's chest. "I don't want to, but I will kill this gaijin kid as well as the shameful heroine Mt Lady if all police within five miles of this bank don't withdraw!"

The Bronze Kneecap gestured to his army of zombies. "I need this money for my research! If you won't let me have it then I'll make sure you will have an international incident on your hands! I can't imagine that whatever country this gaijin is from will be happy about him dying to a local villain!"

A police officer growled as he put down a zombie. "If you kill a hero you're likely toget the death penalty!"

The Bronze Kneecap shook his head. "The ignorant savages of this world have never made the smart choice when it came to acknowledging my work! I will do what I must as a man of science!"

With a sound akin to a bottle cap being popped off, the fist went flying out towards Ben like an arrow. The king of heroes grit his teeth and squeezed his eyes shut. "This is going to hurt."

"Angel sama! No!" The voice of the girl he just met was like a scream as right in front of Ben, a wall of thorns manifested. The wall of thorns emerged from the hair of Ibara as she had cut herself free from her bindings and stood protectively in front of Ben.

"Again with the Angel nickname…" wondered Ben to himself.

"You naive little girl!" Scolded Bronze Kneecap as another fist emerged from his knee. "You should know better then too-"

"Hahahaha!" A deep, cheerful laugh made Ben flinch from the sudden noise, he only had time to blink before Bronze Kneecap was buried in a crater in the floor and all the zombies heads exploded like a tomato shot by a shotgun.

Ben blinked as standing in front of both him and Ibara was a seven foot tall Japanese man with muscles that could give Four Arms a run for his money.

The man had blonde hair with two cow licks sticking up and was clothed in a red, white, blue and yellow costume. He had a smile on his face that put both Ben and Ibara at ease, for his smile was like there was nothing wrong in the world.

"I commend you young lady for protecting your fellow hostage! You need no longer fear, because I am here!"

"All Might!" Ibara's gasp answered Ben's incoming question about who they were looking at.

Ben could FEEL the cheer and benevolence radiating from All Might as if he was a neon sign. Ben for the first time since he was a kid, felt awe in the presence of a hero.

' This guy is much too pure to turn out like Captain Nemesis did! I shouldn't have to worry about him getting jealous-'

A window made out of yellow energy opened up with a sound akin to static electricity. Out of the window stepped a man in his early sixties with a head that resembled of a piece of chicken parm that had been spray painted pink. The man's body was Caucasian and clothed in a black suit with a red tie.

All Might narrowed his eyes. "What do you want Cecil?"

The man with the pink chicken parm head pointed at Ben. "I need to interrogate the anomaly. He's coming with me to The Pentagon!"

Ibara growled and she pointed her vines threateningly at Cecil, as if she was preparing to skewer him repeatedly. "You won't take this Angel away from me!"

All Might sweat dropped. 'That young lady is intense!'

Cecil's amber eyes narrowed at Ibara, before he turned to face Mt Lady, The giantess pushing herself up. "Mt Lady, arrest the school girl if she becomes a problem."

All Might narrowed his eyes. "Hold on, why is this Gaijin child so important?"

Cecil sighed and pinched his flat nose. "Look, all you need to know is that boy is no ordinary child. If he's not a villain I promise I won't harm him."

Ibara looked like she was about to protest some more before Ben spoke up. "You're some kind of government agent, aren't you chicken parm head?"

Cecil fixed Ben with a glare. "Yes, I'm the head of The Global Defense Agency."

Ben nodded. "Alright I'll come with you."

Ibara cut Ben free from his ropes and wrapped herself around his arm after she helped him up. "I'm coming with you! I'm not allowing you out of my sight!"

Ben felt his face heat up as he could feel his arm being hugged by Ibara's chest. ' Her chest is so soft! Like a pillow!' Thought Ben with steam coming out of his ears.

Cecil smirked briefly, a feeling of amusement flitting through his mind. ' Ahh young love.'

"Fine, you can come too. Just step through this portal."

Ibara gave Ben a serious look as if she was a member of The King's guard and he was a member of The British Royal Family. "I swear on my life that I'll protect you Angel-sama!"

Ben sweatdropped. 'Again with the Angel thing…'

{BREAK}

LOCATION: THE United States Pentagon.

And so Ben found himself in a room that to him looked like a void from a children's cartoon he once watched. The room was pure white and seemingly empty, but he could feel otherwise as even though he couldn't see it, he could feel the cold metal of the chair underneath him, as well as the cold sterile restraints that pinned his arms and legs to the invisible chair.

Ibara was by his side, steam coming out of her ears as her heart fluttered at Ben's restrained form.

'Seeing him restrained like this… it makes me want to do… stuff to him. Stuff that my church would say is sinful. Why am I having these desires?'

Cecil crossed his arms over his chest and stared Ben down. "This interrogation is being recorded, and my people have a lie detector scanning your vitals. So we'll know if you lie."

"First question, what's your name and quirk?"

Ben rolled his eyes. "Are the restraints necessary? Anyways my name is Ben Tennyson and I don't have a quirk."

"Oh you poor lamb…" Whispered Ibara with a horrified look on her face.

"You're quirkless…" Cecil stated flatly, with disbelief in his tone. "You better not be hiding anything. If you have a power that's not a quirk, speak it now."

In response Ben sighed and wiggled his fingers on his left hand. "See this watch?"

Cecil eyed the white, green and black device on Ben's wrist. "Let me guess it's some kind of advanced technology?"

Ben nodded. "It's alien technology that allows me to transform into a variety of different aliens."

Ibara's concerned/ pitying look morphed into amazement. "Aliens? Like Omni Girl?"

'So this universe has its own aliens, and this one must be a hero here.' thought Ben.

"What kind of powers do your alien transformations have?" Cecil continued the questioning.

Ben laughed, not in a mocking way but in a friend who's about to brag kind of way. "A better question would be what powers I don't have. I have everything from pyrokinesis to cryokinesis to super strength, super speed, super intelligence, flight, duplication, intangibility, size alteration and more!"

Cecil felt a pit form in his stomach. 'This kid is basically an All for one Jr. With that many powers he could rule the world, maybe take on Omni Girl and The Guardians of the Globe.'

While Cecil felt apprehension at Ben's power, Ibara felt amazement. ' Angel Sama is no ordinary angel! He's an archangel! He could be the next All Might!'

Cecil continued the questioning. "Where do you come from? GDA instruments detected you materializing in the bank with a burst of energy that nearly overwhelmed our scanners."

Ben laughed nervously. "Well, you see… I'm from a different universe. And I have an idea on why I was sent to your universe, though my memory is kind of vague."

Ibara covered her mouth with her hands. 'He really was sent from the heavens!'

"Do you… believe me?" Hesitated Ben while asking Cecil. "Please don't send me to an asylum."

Cecil nodded his pink chicken parm head. "I do, I live in a universe where 80% of the human race have some form of super power, where an alien is one of our greatest heroes. The idea of a multiverse isn't that far-fetched."

Cecil rolled his shoulders. "Anyways… Do you know the reason why you were sent here?"

Ben gave a relieved smile. "I believe I was sent here by a friend of mine. He usually sends me to places where I'm needed. So if I were to guess, I would assume that powerful enemies,maybe even a few of my own, are to appear in this universe."

' He's a handsome savior sent to protect us!' swooned Ibara in her head.

Cecil nodded. "Alright, let me give you the rundown of what my universe is like. If you're going to be staying in my world for the foreseeable future, we need to mitigate how much you stand out."

{BREAK}

Ben rubbed his sore wrists, he was grateful to be free from that invisible chair but he wished that Cecil had set him free sooner.

Now he stood with Ibara by his side in the reception area of The Pentagon.

Cecil tapped on his cell phone before addressing Ben. "Ben Tennyson, you will be staying with Mt Lady. She jumped on the chance to "take in a handsome American boy"." Cecil grinned at Ben's flushed face before he continued.

"She's been briefed on your origins and powers and will be your legal guardian during your stay."

The pink chicken parm headed man tapped his cell phone again and spoke an order into it. "Door to Mt Lady's apartment."

A yellow staticky window opened in front of Ben, to which Cecil gestured for him to enter.

Ibara tried to follow, only for the portal to abruptly close. This caused the vine haired girl to glare at Cecil. "You dare try to keep me apart from Angel Sama?!"

Cecil took a step back from Ibara's sudden ferocity, but he quickly composed himself. "You will see the kid again, I promise. But for now All Might has requested to speak with you."

He spoke into his cell phone again. "Door to Might Tower."

Ibara bit her lower lip and stared at the new portal with hesitation. ' If it's All Might it must be something important.' And so she stepped through.

{BREAK}

And so Ibara found herself in a blue and white room with All Might standing in front of her.

The towering man with muscles that could put a gorilla to shame, laughed with his hands on his hips. "Shiozaki shonen! I am happy to see-"

He was cut off by his own gag as he coughed up three tablespoons of blood and smoke exploded around him.

Ibara's impatient face became concerned, as All Might was no longer the tower of muscle and unbridled optimism. For now he was a tired, and broken man with a body that was skin and bones.

"All Might?! Are you a sinful druggie?!" She raised her vines threateningly. "If so I must whip you now."

All Might coughed up another tablespoon of blood and waved his hands frantically. "Wait wait wait I'm not on drugs! Let me explain!"

Ibara glared at All Might for a few moments before she lowered her vines. "Very well, The Good Lord would want me to give you a chance to explain yourself."

All Might nodded grimly, before he lifted his shirt up and Ibara gasped.

"Your stomach… it looks like one of those zombies the Plague Doctor villain created! How are you- how did you?" Question Ibara with horror.

All Might explained. "I lost my stomach while battling a powerful villain. This villain has countless quirks which he used to cripple me, though I got him pretty good too."

All Might rubbed his mass of scar tissue gently. "Because of this injury, I can only spend a couple hours a day in my muscle form. I have a time limit… that's getting shorter every week."

Ibara felt a chill go down her spine. ' A villain with multiple quirks? Angel sama is powerful but this villain might be able to rival him!' "Why are you telling me this?" Ibara demanded. She could tell this was an important secret that could shake society to its core, so why was All Might telling it to a school girl such as herself?

All Might spread his arms and continued. " I see you worthy of knowing the truth about my power. I wasn't born with this power, it was given to me by my mentor. My quirk which I want to give to you is called One For All."

Ibara's eyes widened. "One For All… you want to give me your quirk?!" For a moment Ibara had an image in her head of herself tall and muscular like All Might.

All Might nodded. "I do, seeing you protect that boy inspired me to act. If you hadn't stepped up, I would have been a bystander watching that boy die."

"There are stories of the beginning of every hero's journey, their bodies move before they can think. I saw that in you and so I saw you worthy of having my power!"

Ibara now had an image of herself glowing with the power of All Might's quirk while Ben was wrapped around her leg and gazing at her with awe as if she was his protector.

"I accept! With your quirk I'll always be able to protect Angel-Sama!"

All Might chuckled. "Well then, my pupil, we will start your training tomorrow! I can't give you my quirk right now, an unprepared body would explode if given One for all!"

Ibara nodded and raised her fist. "I'll train until I collapse if it means getting your quirk!"

{BREAK}

As night dawned on Musutafu, a middle school aged boy weeped and whimpered as he kicked off his shoes while clutching an Urn full of ashes in his arms.

The boy was a heteromorph with a grisly appearance, for he looked like a cat costume that came out of a horror movie.

He was like a bloated cat costume with orange fur and crooked piranha-like teeth the size of spoons. His black Gakuen covered his torso which had a messy hole torn into it, the hole showing his insides which were made of lasagna.

His eyes were bloodshot and the size of grapefruits, tears the size of grapes leaking down his face and soaking the roof he was standing on.

As the moon rose over the city, his wide eyes took in the sight of the multistory drop, of the cars with their headlights on flowing through the streets like blood through veins.

"I'll-" He gave a whimper like a cat that stepped on a nail. "I'll be with you soon mom! I'm I'm I'm-"

He gasped for breath as his grief squeezed his heart like a boa constrictor, all the insults all the pain that Kaachan and his goons caused him flashed through his mind.

"Give up on trying to be a hero! You're nothing but a villain, Neko freak!"

"Help! The Neko Freak threatened to rape me!"

Kaachan licking his lips while unbuckling his pants. "Well well, looks like the hero's got to punish the villain yet again."

He remembered how a girl confessed her feelings for him, only for it to be a trap where she lured him into an ambush by Kaachan and his friends.

The horrific cat costume-like kid gagged and threw up bile as he remembered Kaachan's hands feeling up his body and removing his clothes, as if that wasn't humiliation enough, what followed was Kaachan's erect… He wretched again as his breathing became rapid.

"No more! No more!" Sobbed the cat monster-like kid as he took a step off the ledge.

Only for a calloused hand to grab him by his right shoulder and pull him back onto the roof.

"What the-!?" The kid's exclamation was like a frightened squeak as he turned around to spot his savior, his breath hitching in his throat as he saw a tall man that towered over him, said man wearing a skull-like mask over his face.

"Izuku Midoriya… it is not your time to die. Why kill yourself when you have so much potential to live up to?"

"P-P-potential? Who are you?" Izuku shook like a leaf while he faced the man.

"Your quirk is horrific yes, and so you would be the perfect addition to my League Of Villains. You've suffered so long because of a boy who wants to be a hero. You have been tormented by your peers who condemned you as a villain when you did nothing wrong."

"As for who I am, you may call me Sensei. And I would like to destroy the society that branded you as a villain."

The cat costume monster-like boy licked his giant needle teeth as his grapefruit sized eyes darted from the man to the ground below the roof.

' Should I really become a villain? Wouldn't I just be proving all my classmates right?'

Memories of Kaachan burning his fur with explosions, memories of one of Kaachan's goons using their quirk to make their fingers long and thick like snakes, which he proceeded to shove up his ass, flashed through his mind like a morbid slideshow.

As if reading his thoughts, the man called Sensei spoke again. "Your classmates acted more like villains then you ever did. And one of those villains is on his way to become a hero. Do you really want to live in a society where your rapist can be a hero?"

Izuku shuddered as his stomach did cartwheels, bile rising to his throat. He collapsed to his knees and began to sob.

"Why? What did I do? Why was I violated, why did my mother commit suicide? Why did my father hate me? Why why why?"

The man called Sensei wrapped Izuku in his arms and cooed compassionately and soothingly. "It's alright, you're safe now. Because I am here."

Under his respirator/ skull-like mask, All For One gave a demonic grin at the irony of him once again using that Oaf's catchphrase while recruiting a lost soul.

'I will mold you into a villain that is stronger then your wretched peers' worst nightmares. The world will reap what it's sowed and fear you, Izuku Midoriya.'

{BREAK}

LOCATION: Mt Lady's apartment Musutafu.

In an apartment, Yu Takeyama also known as the hero Mt Lady wiped some drool off her lower lip as she laid on her stomach on her bed, a Tablet clutched in her hands.

"I'm so glad I installed those cameras in the bathroom." An atomic blush with a lustful and goofy smile appeared on her face as she continued. "I originally installed them so I could watch footage of myself showering and make sure that I wasn't ruining my figure."

The gigantification heroine observed the feed on her tablet, which was of a naked Ben Tennyson in the shower scrubbing his body with a loofah.

Yu Takeyama licked her lips. "He's using MY loofah to wash those abs. Abs that I swear I could grate cheese on… oh oh oh he's now washing his cock! I always believed American Men were hung like bulls and I'm so happy to be proven right!"

The Giantess Heroine got up and laid back down on her back as her hand reached in-between her legs. She gasped as her womanhood tingled at her own touch. "One day, I swear one day… your cock will be in my pussy, Ben Tennyson. I promise I will make you pump me full of your American seed, and you will thank me for it."

And so The King Of Heroes continued to wash himself, unaware of his legal guardian's lewd intentions.

Little did Ben know that his legal guardian was growing more and more obsessed with him and that she wouldn't be the last woman in this universe to do so.

AUTHORS NOTES

I hope you Taters enjoyed this first chapter.

Again let me say that this story was inspired by several works such as Avatar Conner's Invincible, Ghouldash97's The Green Devil and a yandere my hero academia girls x male reader I found on Wattpad.

The universe Ben has been isekaid to is NOT the canon MHA universe. It's a fusion between invincible and a MHA AU.

In this universe, Izuku Midoriya was born with a quirk that made him look like SCP 3166.

And Bakugou is an absolute evil piece of shit in this universe, as Bakugou and his cronies have gang raped Izuku numerous times throughout Middle school.

And so Izuku will be a villain in this universe!

Also in this story, Ben will be a member of Class B!

Now for the first villain in this chapter, The Bronze Kneecap, I based him off of the villain from Fairly odd parents but I gave him a quirk that made him like SCP 049.

Anyways I hope you enjoyed this chapter and that you will fav, follow and review!

Later Taters!
