EggDeku

by Akito the Boxer

Not all villains need a sympathetic backstory, a deep character, or a redemption arc. Sometimes they just want a good time facing heroes in a bombastic display of power, skills, and madness to take over the world. It's no fun just creating an empire without heroes to fight. Izuku Midoriya learns how much fun it is when finally meeting his real father, Ivo "Eggman" Robotnik.

-Tokyo Square-

Everything seemed normal in a world populated by people with superpowers as the norms, or Quirks as they often called them. Most citizens possessed unique attributes with various degrees of quality, power, and uniqueness. Some managed to become heroes to uphold peace with a mighty sense of justice whereas others driven by their pride and ambitions became villains bent on taking and destroying rather than creating. No one was ever born equal, and would never be equal in any world, for such a thing would mean everyone is replaceable… And yet, with such simple and broad roads for heroes and villains, the world seemed content in painting itself black and white. It was to the point those not blessed with powers fell on the background, forgotten or ignored.

In some cases, though, someone had to truly break the mold…

"I'VE COME MAKE AN ANNOUNCEMENT!"

During the busy days with countless bystanders trying to cross the roads to work or driving to their next destination, it was helpful for such an announcement that electronic devices were accessible to the masses and easy to hack.

"HEROES AND VILLAINS OF THE WORLD, AND THEIR ADORING FANS AND BLATANT HATERS!" said a figure who appeared on every screen available, interrupting news channels from their usual hero-worshipping and the dribble of trash television shows. "WATCH AND LISTEN TO MY DECLARATION!"

For starters, the people were baffled at the sight of a skinny lad in a rather odd attire. Regarding the wardrobe, the figure donned circular, red-lensed goggles and a green, two-tailed coat sporting two square metal buttons on both sides of the chest in gold with a high collar that hid his mouth and nose. It made it easy to spot who he was other than a short teenage boy with frizzy dark-green hair akin to a spinach salad. The buttons had white straps that ran across the coat's sides to identical buttons on the back. His coat also had silver, zipper-like linings down the back, arms, and front, yellow cuffs, and two extensions on the front that had large silver buttons. In addition, he wore white, cuffless gloves on his hands and a pair of black pants with matching boots seemingly attached to them bearing circular plates on both sides of the ankles and three square ones riding up the shin. Unknown to all, those boots were made for high-speed chases.

"THIS IS DOCTOR ROBOTNIK! GREATEST SCIENTIST IN THIS WORLD OF YOURS!" raising a fist up, the boy took a dramatic pose and kept talking through a voice modulator. "FROM NOW ON, I MAKE IT MY DUTY TO TEST MY MACHINES ON HEROES AND VILLAINS ALIKE! LET'S SEE WHAT YOU'RE MADE OF! OHOHOHOHOHO!"

And the lad even threw his body back in a fit of utter maniacal laughter, confusing everyone…

Meanwhile, in a small room, the green-haired boy took off his goggles, placing them on his forehead to look to the side with so much excitement he was pumping his fists, "Did you see that?! What do you think?! Have I gotten the laugh down?!"

"Yes, big brother, although father's deeper voice helps," mechanically stated a young girl.

"Ah, well, can't just outshine the original from the start," the brother told his sister, but still giggled giddily. "But now we can truly test it out! After all, that's why father and you are here, Sage-chan!"

"…yes…" the girl said and looked away.

Sage resembled a young human girl but was obviously not flesh and blood if one looked at her. While she could pass for a normal human in the world of heroes and villains due to having a slim body and limbs with white skin and a round face with a tall forehead, there were some traits one could not call normal. Notably, she possessed glowing red eyes and a red energy structure on the left side of her face. The petite, seemingly 12-year-old girl, also had short white hair with a swirl in it on her forehead and a single red energy highlight inside said swirl. For those who would consider that normal, the rest of her body, especially her arms and legs, were completely black with outlines of red computer code around them. Unlike her big brother, she wore a black cloak and shoes covered with red computer code outlining the insides and most of its right side.

Faint as it was, a small smile spread on her face at the compliment of her fleshy brother, who was tapping his fingers in deep thought, then held his chin… and started to mumble, "Right, so with the declaration of war, what we need to focus on is making the strike matter. While we've discussed the possible routes heroes both new and old can take to answer to my confrontation, the matter of offense, defense, and mobility along my prototype's design will-"

"Brother, you are mumbling again," she stated in a monotone.

"S-sorry…" he meekly rubbed the back of his head, then looked for a switch.

Light depicted the room as that of an average teenage otaku in Japan. Posters depicting a muscular hero whose blonde hair was slicked back yet had two strands standing up over his forehead like a pair of bunny ears. His beaming smile and USA-themed outfit complete with the three primary colors and stars were something any child would want. There was a bed, a desk, and a computer with three screens. Next to said desktop was a round metal disk projecting Sage's image and a large, red, metallic backpack which the boy went to grab. It was a bulky, square container which at a glance was akin to a suitcase with runes which he strapped on his back with a 'hup' from his lips.

"Data from the Egg-Pack prototype has been updated to all Badniks, brother," Sage told the boy.

"Only one way to find out if it works…" the salad-head doctor whispered with a shake. "I'm so nervous and excited it's like my feet are dancing in my stomach while glued to the floor…"

"How is that sensation possible?" Sage asked with a cold yet focused look, telling him with her rather emotionless yet intense stare that she wanted to aid him.

"Uh, yeah, this is one of those things that make sense only if you're too nervous to speak…" the boy chortled sheepishly. Having the small girl so eager to help was a breath of fresh air, so with a little more confidence, he pointed to his window, "Let's go make it big and loud! Sage!"

"After you, brother," the girl nodded and disappeared in a flash of red light.

Opening the window, the boy let out a big smile under his collar as thrusters popped out of his backpack, propelling him into the air with what turned out to be a jetpack with a yell:

"G-FORCE IN MY FAAAAAAACE!" the boy cried as he flew at supersonic speeds.

During the time of his declaration and the time it took for him to fly to his destination, the police had arrived to investigate a strange artifact. It was a large, purple cube-like object with mechanical arms and legs folded onto the sides and covering some sort of head. The strange item sat in the middle of the crossroads stopping all traffic and angering the usual pedestrian and driver…

"Up in the sky!" a woman pointed out.

"Is it a bird?" a man asked in disbelief.

"A plane?" a boy heard a jet turbine.

"No, it's…" someone was about to say, but the result was spectacular.

"This! Ow! Needed! Ah! Much more! Ouch! Thought put! Mama! Into it!"

Everyone winced as a short boy with a jetpack landed face-first on the floor, bounced off it, and crashed again. The citizens did so in perfect harmony, too. When the child hit the streets, flipped in the air, and bounced, every person would grimace and either suck air through their teeth or tense up. Alas, all things had to end, and the young lad arrived at his destination… with a surprising skip on his step despite the harsh landing. Pulling out a pen and notebook from his backpack, he began writing away what he had found.

"Hey, uh, are you alright?" a police officer didn't know what else to say.

"Okay, so, the thrusters will need better calibration," the young doctor said to himself and crossed a number on the blueprints of his jetpack, writing a new one. "Well, this is why father told Sage and I to do proper test runs before I began this path…"

"Buddy, mind telling me what's going on?" an officer started.

Rather than answering, the young doctor turned, "Sage, if they interrupt me again, please look up their search history."

"Done already, brother," the holographic girl told him with a deadpan expression which soon turned into one of disgust to a particular policewoman. "Cease your approach on the doctor or the officers shall know of your story involving the Biker Mice from Mars and a character who shares your physical description…"

Said lady officer held up her hands in surrender as the child doctor finished, "Greetings, people of Japan, and be welcome to my demonstration!" the young doctor Robotnik told the audience with a dramatic turn and even more theatrical pointing of the finger at his audience, "For I will show you all what a real supervillain can be like!"

"Yo, buddy, how about cutting the crap and letting us get back to our jobs?!" a random office worker shouted from his fancy car.

"Cut off the doctor again and your boss shall know of the company assets that went to paying for AI generated pictures of your original character in Disney's Robin Hood," Sage threatened with her look of disgust growing deeper, shutting up the man.

"Thank you, Sage," the boy nodded before aiming a finger up. "Now, let's give them a show! Give me one with a beat, too!"

Jumping into the air, the green-haired Robotnik used his jetpack to merge with the artifact on the crossroads. Everyone watched as the arms unfolded and thrusters propelled a large robot after its maker. It had long arms and triple-jointed legs which were even longer, easily as long as telephone poles, but all limbs were three times thicker. The main body split up, shooting out thick wires which attached to the doctor's pack, pulling him into a humanoid robot's open belly. Once it landed on the street, the mech revealed itself to be an insect of steel of a particular variety as its red eyes glowed menacingly at the finally terrified audience. A pair of jagged slabs of metal spread from its back, shooting a blue flame which took the form of wings flapping at high speeds while its simple head a golden drill popped out from what looked like a mouthpiece. Everyone could see the boy took heavy inspiration from the mycetophila fungorum, a mosquito.

"Oh… crud," an officer gulped, then blinked. "Is that…"

Inside the mech, the young doctor smiled as wires and steel merged around his arms, creating large red gauntlets, while his feet slipped into matching red metal boots. A screen display appeared to show him the outside, the robot's status, and an icon with Sage's face. The Chibi drawing of his sister had a neutral expression as she spoke up.

"All systems are operational, brother," she nodded. "Docking is a success."

"Now let's take the Egg Mosquito for a test drive," the boy cheered and punched his fist into his palm with the laughter of a true mad scientist. "OHOHOHOHO!"

Outside the cockpit, the robot mimicked the motion with the onlookers finally having the neurons to scream, get out of their vehicles if they weren't already, and run away. They didn't get too far away before the child doctor found a direction to go and flew forward, the mechanical mosquito began pelting the innocent bystanders… with paint. Everyone stopped upon seeing the pectorals of the mech pop open. Balls of steel plummeted down only to explode before hitting the ground and showering everyone and everything with paint.

"Is this a sick joke?!" a man asked with his expensive white suit turned into a psychedelic canvas of pink, green, orange, and purple splotches.

"Come out, come out, wherever you are, heroes!" the doctor cackled, though he was a tad too cheerful, giddily bouncing on the seat which his jetpack provided.

"Brother, it appears one is already attempting to intercept you," he heard Sage tell him worriedly, a genuine feeling that displayed the greatness of her intelligence; even her icon showed her concern.

"Let's make it fun, then!" the lad cheered. "Who is it?! Is it one of those rookies getting too big for their britches?! A pro legend?! Tell me it's Endeavor, I've got to try my new bombs with him!"

"Kamui Woods," Sage explained.

"Ah, the wooden hero and current heartthrob!" he cheered and pumped a fist. The robot flew high into the air, spotting said hero thanks to the man sending out thick branches towards the mech, "Fancy seeing you, hero!"

…and the Egg Mosquito pointed as dramatically as its creator to the hero, who scoffed, "Don't think you can just prank everyone, brat!" the masked man stated, placing his hands onto the floor to create a gigantic Sakura tree that pulled him towards the mech, "What are you planning?!"

"To turn the world of heroes and villains alike upside down as a true supervillain!" the boy told him before his mech dashed to the side. He angered the hero more by wagging a mechanical finger, "I'm going to battle the best and test them! Open your heart and show me what you've got!"

"Canyon Cannon!"

"Bwah!"

The young doctor's declaration was cut short when a giantess high-kicked him. The woman, a blonde currently five times his mech's size, turned to smile at the onlookers… and even had the audacity to arch her back in a way which propped up her rear for pictures to be taken.

"Not bad for a newbie pro, huh?" she winked while Kamui Woods stared in disbelief as the mech flew off into the distance. Inwardly, she was smirking at the attention of her new fans, drunk on a sensation of pride and vanity, 'Should've come off with a butt-related pun, but this was last sec… Oh well, with this, my popularity and rank will surely-'

"Indeed, not bad."

Both the heroine and Kamui Woods gaped as the mech appeared in front of her a split second before its bomb chutes opened. Throwing its arms back, the Egg Mosquito pelted the giantess with more paint bombs. Her new fans yelped and ran for cover as the giantess tried to swat him away. Of course, having jet wings, the mech maneuvered away from the woman's hands. It analyzed her in a millisecond, showing the young doctor in the cockpit the woman's data. Sage's icon had a frown as she noticed it included her measurements.

"This heroine is known as Mt. Lady, brother," she stated with irritation in her usual monotone voice. "Rookie who has been taking other heroes' marks to get ahead. Cooperation level 2 may be too kind for someone like her on your chart."

"And this is why we're testing them," he grinned and took notice of Kamui Woods. Said hero had climbed onto the giantess' shoulder and took aim at him, "That's better!"

His joyous exclamation did shock the man a fraction of a second, but the hero still latched a thick branch from his wooden arm around the robot, "Drop the act! You're just another villain!"

"Did you not hear me?!" the young Robotnik exclaimed. His mech's wings boosted him and the hero up into the sky at high speeds, dragging a screaming Kamui Woods high into the air, "I'm not a villain! I am a supervillain!"

Kamui Woods was quick enough to shoot his free arm to Mt. Lady, who after wiping the paint off her face reacted fast and grabbed the branches he extended. Both heroes struggled to keep the big bug from flying away, much to his amusement and the duo's irritation.

"Oh yeah, what makes you so super?!" the giantess asked.

"Presentation!"

Throwing its arms back, the mech bombarded Kamui Woods' arms with new bombs. Instead of paint, the new balls dropped a thick oil that slipped all over the duo. Mt. Lady let out a yelp when noticing her grip on the wooden hero's branches. Said man could feel the Egg Mosquito was about to let loose, and seeing as he wasn't going to stop the mad doctor, there was no choice. Letting go of the villain, he landed onto a rooftop… and slipped as did the giantess. Both heroes fell onto their rears with increasing frustration, which grew when the supervillain began clapping and laughing.

"How do you like me now?!" the mech even began to pose in a rather fabulous manner with a hand to its head and another to its hip in a bizarre display of menacing villainy. "Beating me at this level of superhero prowess is useless!"

"So you say…"

Hearing that voice, the doctor went stiff and looked down at a large figure with a large, proud back that embodied strength, heroism, and, above all else… hope.

"Can it be…?" the young Robotnik asked.

Witnessing that magnificent smile and hearing the next words made everyone feel at ease, "I am here!" said none other than the legendary All Might as he jumped at the Egg Mosquito with a fist ready, "Detroit!" he smirked at the supervillain, "Sma- Huh?!"

"All Might!" the doctor's cockpit opened, stopping the hero's punch from connecting for he did not want to harm a child, just break his robot.

Due to his indecision, the Egg Mosquito had to catch him… and gently fly him down as the young doctor Robotnik apologized, "Ah, my bad! I didn't mean! Well, I should have, but… Let me take it back from the top, alright?!"

Utterly baffled as the Egg Mosquito set him down on a rooftop, even patting his shoulder to dust him off, the hero waited as the supervillain paced with his mech back and forth, clapping the claws of his robot together nervously.

"Young man, what are you doing?" the hero asked.

"Can I get your autograph?" the boy asked giddily, providing him with a notebook and marker.

"I sure can if you answer some questions, young man," All Might actually did with an amused grin. "Truth be told, I'd rather face more villains like you who don't cause large scale property damage."

"Oh, you've got no idea what this means to me!" the doctor exclaimed, then clasped his hands in front of his face… with the Egg Mosquito mimicking him. Clapping his face to wake himself up, the doctor kept his back and forth pacing with a hand behind his back and a finger up, "I shall not talk your ear off and bore you with details, my good hero and archnemesis!" he paused… and rubbed his hands in excitement, "That sounded so cool to say!"

Chortling as he could see a good if… odd was an understatement… bizarre child, All Might helped him continue with his arms crossed and a patient smile, "I shall listen, then."

"You have my gratitude," the young Robotnik tried to be serious resuming his previous stance with both arms behind his back. "Even you see the current state of heroes and villains, right?"

"Criticism like yours is quite extreme, though," he countered.

"Good assessment, but you avoided answering," the doctor continued, wagging a finger up. "The heroes of today are more interested in fame, money, glory… And none remember what makes you the greatest of them all…" he turned to All Might, leaning in to point at the notebook, "Oh, and can you add to Doctor Robotnik?" as the hero did as told, complete with a message of kindness and for self-improvement, the salad-head continued, "Villains are driven by simple desires without much of a thought put into it. Although, yes, even my father is like that."

"Who would your father be?" All Might asked while handing him the notebook.

"Why, the great Ivo Robotnik, genius scientist from worlds apart and unparalleled supervillain who has even embraced the title!" the green-head exclaimed and pumped a fist dramatically. "And he's been aiding me in his plans for world domination by having me test you heroes!"

"…you're awfully polite for such goals," the man replied slightly tenser than before.

"Can't make an omelette without breaking some eggs, as he'd say," finally, the cockpit closed and the Egg Mosquito took a stance, leaning forward with its arms to the sides. "And I really want to see what real heroes are like, even if I have to be a villain! It's no fun to have a hero who doesn't fight a great bad guy, and I am a super one!"

"Then I better make the cut as a superhero, young Robotnik!" All Might stated and raised a fist.

"Ah, this is going to be great!" the boy gushed balling his hands to his face, which his mech also mimicked. "How should I start?! What perfect line to define my tone and declare myself a-"

"Focus, brother," Sage urged him, not having the heart to stop him before, but seeing that he was about to go into what she had come to refer to as nerd-mode in front of the top hero of his world right as he was about to fight him was a far different situation.

"Let me say it's an honor to fight you, All Might, sir!" the doctor blurted out due to his sister's words and having to get out at least one final compliment.

Locking up the cockpit, the Egg Mosquito brought up its fists and throwing a left hook at All Might, who replied in kind, "Same to you, young Robotnik!" he roared out his attack, "TEXAS SMASH!"

Vocally announcing his attack didn't give the young doctor enough time to block it as the man was far faster than regular people. Instead of putting up his guard, the salad head and his giant mech were flung backwards with powerful gusts of wind. Anyone would consider the battle won… if they had not been paying attention. Strong as All Might was, he was still fighting a supervillain…

"Just like your battle against-"

"Brother."

Hearing his sister chastise him again, the young genius righted his mech in the air and spread its wing units. Using the turbines to keep himself afloat, he had to fight back his urges to admire the battle. Blood was pumping, ideas ran at thousands of miles per millisecond, and he was about to lose his lunch if he didn't calm down. A quick slap to the face, which surprised All Might who had to see the mech smack itself, helped the green-clad mech pilot to get his bearings.

The battle to decide his road as a supervillain had just begun, "Not bad, All Might!" he tried his best to taunt, but he genuinely and sincerely complimented the hero. It was hard not to, the man looked far too cool in that dynamic pose, "Get a load of this!"

Abusing its advantage as a flying mech, the Egg Mosquito circled around All Might, who kept his smile. It was when the machine picked up speed that the hero started to worry. The first time the robot flew in a complete circle around him, it was still easy to keep track of. Second time made it as hard to spot as an airplane. By the third time, it was a blur, and it kept increasing how fast it went.

…until it disappeared, "Either above or behind!" he exclaimed and turned, looking at an upward angle which allowed him to see if the enemy could be coming for a strike to the back and also lift his gaze in case he was high in the sky, "Ngh, the sun… Clever!"

Indeed, the doctor used the bright sun to blind the hero and launch his mech for a classic move straight out of a fighting game, "Foot! DIVE!"

Jets of flames propelled the Egg Mosquito even faster than before as it slammed its metallic foot on the hero. All Might could do nothing but take the strike, much to the shock of the onlookers and his face. People who believed in him and wanted the hero to succeed sucked in air as they saw the man get dragged across the rooftop on the mech's foot. It finished with a skidding halt and a thick cloud of smoke which covered everything. Many actually feared their hero was seriously hurt…

"AHAHAHAHAHA!"

But he laughed!

"Still amazing, All Might!" the doctor cheered as the thrusters spewed thick flames, but the robot could not move the hero, let alone make him buckle his knees.

"You're too kind, young Robotnik!" All Might exclaimed, and punched the robot's leg clean in half. "So I'll take that enthusiasm and reward it with some of my best!"

Sage grew alarmed, "Brother, he's about to-"

He knew… "He is!" the green-head cheered, "That's the Detroit-"

"SMASH!"

Everyone erupted in cries of shock and awe as not only did the strike split the mech in half, leaving a baffled doctor still seated in the destroyed cockpit, but it created a blast of pure brute force that cut a hole into the sky which cleared the weather.

"That was…" the doctor started in awe, eyes wide as his goggles were flung off. "It was…"

"It is over, young Robotnik," All Might stated calmly. "Your robot was amazing, but I cannot go too easy on you as the Symbol of Hope."

"…amazing…"

"Huh?" both Sage and All Might couldn't understand that response from the doctor.

"ABSOLUTELY AMAZING!" the doctor leapt off his robot, landing in front of All Might.

"Young Robotnik, are you-"

"More than fine!" the youth exclaimed, pumping his fists as his jetpack retracted the wires which connected it to the main body of the mech. "That was your Detroit Smash! It was the legendary Detroit Smash which was needed to truly defeat my Egg Mosquito in such a spectacular fashion!" he grabbed his head as the excitement got to him, "Not only that, you ensured the blast would not leave debris here! Judging by the power and air currents, it should land on that beach which many use as a junkyard! And you did it after stopping my mech without letting it break the building!"

"…you're going to make me blush," the hero admitted in slight confusion, yet had to chortle at such energy and enthusiasm. "Young Robotnik, are you sure you wish to be a villain?"

"Oh, absolutely not," the green-head waved a hand. "I want to be a supervillain…"

"Perhaps we could talk this over at the station," the man offered him a hand, but the youth refused with a wave of the hand, then he wagged a finger.

"Don't expect me to hold back after seeing that!" the genius boy exclaimed. "I have to try to one-up myself! My next mech has to truly put you and heroes to the test! And it has to be and look cool while doing it! Oh, I can hardly wait to see how incredible the battle will be!"

"Commendable as your inspiration and drive as, you cannot run away, my boy," the hero reminded the supposed supervillain.

"But that's what makes me more than a villain," the kid genius stated, throwing his arms to his sides. "A dramatic exit! Sage!"

All Might nearly choked on his own spit when the Egg Mosquito threw dozens of bombs into the air. Part of him figured they would be more paint bombs like before, but with his experience and a long history of facing true evil, he could not take any chances. He raced after the bombs, ready to strike them all with his mightiest punch if needed to blast them away…

But then, his side stung, causing a streak of blood to come out in a cough for the one second the bombs needed to explode, "No!" he shouted, reaching out to the explosive… and saw water, "Uh?"

Rattled by the fear and then frozen by the confusion, All Might watched the water bombs spray the thick layers of paint and even oil which the doctor covered the city with. Everyone watched both liquids drip onto the sewers, cleaning the place after scaring them half to death. Both Mt. Lady and Kamui Woods had already formed a barrier to keep the civilians safe, but got a decent shower which left no stains on their or anyone's clothes.

"Cheeky kid…" Kamui Woods growled.

"Why thank you!" everyone watched the young doctor flying in the air at a safe distance from All Might thanks to his jetpack. And then he remembered what all supervillains had to do, "I mean, uh, I'll be back! You heard me, heroes! Doctor Robotnik will be back to show you why I am one of the greatest scientist minds in this world! You will see me build my empire! OHOHOHOHOHO!"

Having nothing left to say, the genius flew off at speeds All Might had never seen, leaving a baffled hero behind, "Quite the shame he took this path… Maybe he had what it took in another life…"

Meanwhile, said supervillain turned to his sister and assistant, "How was that one-liner for the exit, Sage? I know I rushed it, but did I get the laughter right?"

"Hm," the holographic girl said as they zipped through the clouds. "I'd say a seven out of ten. Your focus needs more polish if you wish to be a true supervillain, brother."

"Don't call me that when we're alone, Sage," the boy said as he landed atop an abandoned warehouse, taking off his goggles and opening his collar to reveal green eyes and a freckled, youthful face. "You can call me by my name, you know?"

"I am still your assistant per father's command," Sage stated firmly as the roof shifted to allow them in through an elevator. "My duty is to keep you and father safe, that is what I had been programmed to do originally, and I intend to do so."

"Pretty please?" he pleaded, clasping his hands.

"…I shall try, bro- Izuku…" she glitched slightly, her clothes turning white for a second as her eyes and the glowing red became green in that fraction of time.

"Whoa, you're still evolving!" Izuku beamed, looking her over.

"Tell me, brother…" she said after returning to normal. "Are you sure this is the path you want?"

"Like I told All Might, yes," he restated as the entrance closed. Sage didn't need to see in the dark to know a frown spread on her brother's face despite his attempt to keep a smile, "If not for you and father's timely arrival… well, I don't know what I would have done…"

"Fret not, bro… Izuku," Sage started, her eyes narrowing dangerously. "Shall I find that boy, he will assuredly be made to regret his every word and action toward you."

"Oh, now I almost feel sorry for him," Izuku admitted with a chuckle, ruffling his hair. "But do not worry…" he clasped his hands as the elevator stopped, letting him see a collection of mechs he had just started to build, "After all, if father taught me anything is that if you do not succeed, you just have to try again and again while having a blast piloting your newly improved creations."

"Indeed," said a figure which had been waiting for Izuku. "Welcome back, my boy… Are you ready to have a little bit of fun battling more heroes?"

"Of course, dad," Izuku beamed.

"Excellent…" the man who had been sitting in the shadows exclaimed, standing up with a large grin. "Onward to the first step to creating the glorious Eggman Empire! First, we turn this city into the greatest amusement park in all the galaxy, and then the world itself will be our playground!"

"With plenty of heroes to test and fight as we do!" Izuku exclaimed.

Both father and son had to share a laugh, "HOHOHOHOHO!"

Sage could only look confused, "Shall I tell mother we'll be late for dinner?"

That halted the mad laughter as father and son looked at each other, then at her.

"Five minutes to gloat, then katsudon," Eggman stated.

"Alright!" Izuku cheered.

-TBC-

This is my first step at rebranding myself, trying to do something far different from my usual while also using something I am somewhat familiar with.

Now, why make Izuku a villain? Because I am tired of the edgy villain Izuku fics where there is far too much angst. Like, I get the appeal, but I'd rather see the goofy side of villainy. Twirling a stylish mustache while gloating, creating elaborate and ludicrous ways to get heroes in trouble, and all around knowing you're evil and owning it.

Who better to do so with than Eggman himself? He needs no introduction, and he doesn't need any depth to work. Unlike the villains in canon My Hero Academia, Eggman is the glorious Saturday morning cartoon baddie we want to see to be entertained by rather than having a story telling us a bad guy is someone who had a bad day.

It can work, yes, but I also want fun!

Big Jack Horner worked in Puss in Boots because we've been bombarded left and right by horribly set up twist villains and supposedly complex antagonists who are misunderstood.

Oh yeah, that can be good… but I also want someone who is easy and fun to hate because they kick puppies for fun before a righteous hero pummels them.

Let me have my fun, and you can have your angst.

Anyway, Izuku will still be a cinnamon roll, he will have Sage to act as his assistant, and he will not be paired up with her, so don't even ask nor fret.

Regarding how Eggman got to have Izuku with Inko… just picture him as portrayed by Jim Carrie before he let himself go after his obsession with beating a certain blue blur.

Akito the Boxer here, up to hang his gloves.
