Glad to see the last chapter was well-received!

I do realise that the preview shown in the previous chapter would be quite the surprise for almost every one of you. Yes, that is indeed Tenko Shimura/Tomura Shigaraki. As I said a few chapters back, this story is going to go far different from canon.

Old Reviews

JP922: They aren't going to force him or anything, but some aliens may talk to humans about Izuku's exploits in Undertown and how he helps maintain justice there.

MIKE202303: Thanks for your review!

Broken Requiem: Alright then, Water Hazard will be in this story.

WonderDildo: Thanks for the heads up!

Great wolf dragon: Alright then.

Sincere Akuma: That's the plan.

God of Hentai: Vote noted. Thanks!

ProjectIceman: Yup, I noticed that in the other fanfics where Izuku gets the Omnitrix, he was a teen. So, I've decided to, like Ben 10, make Izuku receive the Omnitrix when he was 10 and become a vigilante.

duskrider: Thanks for your review! I've consider a fusion.

rmarcano321: Thanks for your reviews! I'd say that Izuku is less brash and reckless than Ben and makes more use of strategies and his intellect.

Jss2141: Alright then, I'm guessing you want Water Hazard.

Aztec 13: Thanks! Nice to see that you're enjoying my story!

Guests 1 and 2: Thanks for the reviews! Also, I'll consider the name Waterflow, thanks Guest 2!

Gamelover41592: Thanks! I just kept Jimmy as people would recognise him from the original continuity.

Amit Barabi: Okay. That's the plan! Also, it's true that Izuku and Ochaco go to different schools, but you will see interactions between them in the story.

CCSakuraforever: ¡Gracias! Apuesto a que te va a gustar este capítulo.

Fusion: A fusion sounds good. Thanks for your review!

jxckxt1: Thanks! Nice to see people enjoying my story.

Max: Pardon?

Piccolo: Sorry, but it's looks like you're in the minority.

Speedsters and Arrows: Thanks for you review! It's always nice to see people liking my story. I'll take your ideas into consideration.

Finn: Sorry, but you're in the minority. The finished product will have some Overflow elements though.

Magi: Not sure, I'll have to ask the Ink Tank first. However, I don't think they'll allow.

rmarcano321: Thanks! I find that it's nice to answer any questions my readers have. My favourite superpower would be the ability to create anything I want, fictional or not, without limit and have it be under my complete control.

New Reviews

Grimlock987: Yup! And that's not the only change in this universe!

Southparkfan123: You'll see in this chapter.

Amit Barabi: Glad to see that you like it!

Gamelover41592: Izuku isn't truly the new All Might yet, but he is pretty famous at this point. And yes, you didn't see a good Tenko coming, did you?

So without further ado...

Chapter 5: The Plumbers

OOOOOOOOOO

Once upon a time, Roxanne "Rojo" Johnson was a veteran who served in the US military, having done two tours of duty in Iran. Despite the many disciplinary problems she had, she was an effective soldier and was lauded for her creative use of her quirk, Knives, which allowed her to create and project knife-like blades along her arms and hands.

Sadly, Roxanne had the misfortune to step on a landline while on a scouting mission, cussing the loss of her left leg. This, combined with the problems and tensions created due to her growing pride and an incident where she slashed a platoon mate, the woman was discharged from the military.

Like many other veterans, she had trouble finding work, especially after potential employers took a look at her history of violence. As a result, Rojo booked a flight to Japan as soon as she received her prosthetic right leg, having heard good things about the county.

Unfortunately for her, her situation did not improve. In fact, it seems the universe just had it out for her. Firstly, she couldn't get another job for the same reasons as in her home country. Next, her apartment in Musutafu City was destroyed during a villain battle and, as she wasn't a citizen of Japan, she didn't receive any form of compensation.

Desperate for cash and wishing to burn off some steam, Rojo was more than happy to join in on several heists. With some hostages, no heroes would dare to stop her and her crew.

At least, until The 10 showed up.

The supposed group of vigilantes would foil her plans time and time again. No matter which member showed up, Heatblast, Diamondhead, Four Arms, they'd always stop her gang's plans and get her arrested. In each of her stint's in prison, the former soldier would dream and fantasies about gutting each and every member of The 10 and keeping their carcasses as trophies.

At least, until someone revealed that everyone in the group was, in fact, one teenager the name of Izuku Midoriya who transformed into aliens.

To say that Roxanne Johnson was shocked would be an understatement.

Absolutely INSULTED would be more on point.

She, a veteran with a useful quirk for combat and the leader of a dangerous gang, was taken down not once, but multiple times, by a 10-year-old child. Rojo knew that she had to get even.

The American's contacts outside the prison managed to, with the help of a broker named Giran, find help with the skills needed to break her out. Once that was done, getting out was a cinch for her.

Now, Rojo and her gang wore their equipment and on their trusty motorcycles as their began to out their plan into practice. If you asked Rojoabout her plan, she would've puffed her chest out with pride. During her gang's planning session, she made sure to take into account a weakness that any hero worth their salt would have.

Like any other hero, Izuku Midoriya would never let an civilian get hurt.

Rojo intended to exploit that weakness.

OOOOOOOOOO

"What kind of name is Chrono Spanner?"

Izuku eyed the armored stranger extended hand, which interestingly had six fingers, with caution. Judging by what he saw, this "Chrono Spanner" had some kind of telekinesis quirk. Having dealt with several villains and aliens with similar powers, the greenette knew that he had to tread this situation. He didn't know why the telekinetic exposed his secret, so he needed to-

"You may wish to know that you've started muttering, Izuku Midoriya."

Hearing the statement, Izuku cursed his loose lips. His persistent muttering habit had probably given away his thoughts.

"Do not worry, I am not your enemy. If I was, I would have snapped your neck by now."

"... That doesn't fill me with comfort."

Now tense again, Izuku levelled his stern gaze on Spanner. "I have questions for you, and I want them answered."

Seeing the stranger nod, Izuku continued, "First off, how-"

"How did I know your secret? Pardon the interruption, but I expected this line of questioning.

Ignoring the look the greenette gave him, Spanner gave his answer. "I do realise that this-"

"I AM HERE! I AM HERE!"

The loud words made both Izuku and Spanner jump. The former inwardly cringed, he thought he had changed his ringtone a long time ago! Raising his phone, the greenette saw that the caller was none other than his sister, Izumi. "Sorry, Izumi. I'll talk to you later,"thought the teen as he declined the call.

"As I was saying, this may sound disturbing, but I have been observing you for a very long time. Ever since you started performing acts of kindness and heroism, from your earliest days of simple acts of compassion to taking down corrupt heroes, I have watched with admiration."

"As for why have I revealed your powers, it is because I foresee that hero society would need someone like you. We both know that the system that is currently in place is too flawed and in need of change."

Izuku scoffed in response, so this Spanner was a aspiring. "From what I've seen, it's too ingrained into Japan's culture. It'a impossible for me to do anything about it."

Upon hearing that, Spanner walked towards him. Izuku's expression hardened, prepared for a confrontation. Spanner seems to pick up on this, raising his hands in the air. "I know you are an intelligent young man. I am sure that you have realised that there are some humans out there who would not take kindly to aliens, on Earth. You just need to use the influence you have and will possess to-"

"Let me stop you right there," said Izuku as Chrono Spanner stuttered for a while, surprised at being interrupted. "I recognise the benefits that embracing my fame can bring, but I won't risk it. For my own good, I-"

Just then, a beep could be heard from Izuku's phone. Holding it up, his eyes widened as he saw an alert that was titled: "VILLAIN ALERT. COORDINATES SENT."

Wishing to know more, the teenager unlocked his phone, his eyes widening to see none other than the biker gang leader, Roxanne Johnson, with her gang taking the owner of a takoyaki store hostage. Better known as "Rojo", Izuku remembered dealing with the American villain multiple times over rather past few years. With the foreigner's temper and violent tendencies, she definitely had to be stopped.

"Sorry, but I think I have to-" Izuku's sentence was cut short when he raised his head and, to his mild shock, saw that Chrono Spanner was gone. Taking a quick look around, it didn't seem Spanner escaped through the warehouse windows or even the roof. The telekinetic being had vanished with a trace.

Sighing at the disappearance of Chrono Spanner, Izuku activated the Omnitrix, made his selection and slammed down on the dial.

One flash of green light later, where once was a human being stood a hulking, broad-shouldered alien with yellow armor plating on his back, shoulders and his arms. Cannnonbolt, without amother thought, then curled up into his signature sphere form and, like a motorised wheel, smashed through the the warehouse wall and rolled away as fast as he could to stop the villains.

OOOOOOOOOO

As his helmet collapsed into his suit, Toshinori Midoriya took a deep breath as he slumped against the wall of his team's hideout. He had teleported out of the warehouse as soon as he saw his father receive the alert. The brunette would hate to be the reason why Izuku couldn't make it to a crime in time. The teen had hoped to warn his father of certain events and measures, he even avoided using contractions to make him sound more formal. However, it seemed as though his father had become a little too jaded. There had to be a way to instil some hope into the cynical vigilante. Perhaps-

Chu

Feeling a familiar pair of lips on his cheek, Toshinori broke out of his muttering and turned his head to the left to see a girl with wavy, purple hair down to her waist and wearing a purple spandex suit, complete with a cape on her back.

Playful, purple eyes stared at the male teen as the girl wore a smile on her face. "You know, it's times like this that remind me that you really are your dad's son."

Rubbing his cheek, Toshinori couldn't help but blush. "Hikaru, it's good to see that you've completed your mission early. Have you received the intelligence?"

Hikaru Iro nodded as she raised her hand and muttered a few words. A pink sphere appeared on the ground, disappearing to reveal a suitcase. "Yup, Toya really came through. You'd think the MLA would suspect him by now?"

Grunting, Toshinori replied. "With some teleporting and 'property damage', the heads of that villainous group would never suspect that thefts are being committed right under their noses."

The telekinetic was then caught off guard when his girlfriend wrapped her arms around him. The increase in weight caused the duo to gently fall into a nearby chair. "I know, it's just that I wish that there wasn't a risk of Deika citizens being hurt. I mean, they're more brainwashed than anything else. You get it, right, Toshi?" Hikaru then looked up to see the teen smile softly and nod at her, unaware of how Toshinori felt somewhat otherwise.

After all, giving his villainous excuse of a grandfather a "little nudge" in the direction of All Might's fist had paved the way for a better future to be created. If Toshinori had to sacrifice anyone to achieve success, he would reserve it for those whose actions showed that they deserved it.

"Hikaru, however, doesn't need to know that," thought Toshinori as the couple snuggled into each other, happy to have sone privacy at last.

OOOOOOOOOO

With some kind of sixth sense of which the exact nature was unknown to its user, Cannonbolt navigated the streets of Musutafu with ease, dodging vehicles and people alike despite his relatively large ball form. "Now then, if I remember correctly, the takoyaki store should be located right here."

His thoughts were confirmed when the vigilante turned around the corner and uncurled. He laid his eyes on several policemen surrounding the takoyaki store. Through the broken glass, Cannonbolt could see a trio of bikers, all of which, for some reason, wore colour-coded armour.

"Judging by the state of the store, it appears that they've rammed their motorcycles straight into it without regard for safety," thought Cannonbolt as he tried to think up a strategy. "Maybe if I-"

"There you are, you little shit!"

As soon as Rojo's exclamation was registered by Cannonbolt, the elderly store owner went flying out of the store and into two unfortunate policemen. After that, the three femme fatales jumped on the bikes and, without any hesitation, turn on the ignitions.

The bikes came faster than the Arburian Pelarota expected. He couldn't curl up in time as the women rode past him on their bike, the speed causing him to lose his balance and fall on his back.

Rojo laughed as she saw her enemy attempt to get back on his feet to no success. "I knew doing something like this would draw you out, kid. You heroes are all alike," declared the villainess as she wore a sadistic smile and a sharp blade grew from her right hand.

"Now, you're finally gonna pay for making me look like a damn idiot! You can't defeat all of us, kid!" proclaimed Rojo as one of her henchwomen, the one in blue armour, drove her motorcycle towards Cannonbolt, intent on ramming the fat alien vigilante.

The transformed teen scoffed as his hand found its way to the symbol on his chest. "Actually, yes I can!"

Just then, there was a green flash and the blue biker, temporarily blinded, felt her bike run over a puddle. Curious, the villain stopped her motorcycle and turned to see a black metallic blob with glowing green lines jump towards her vehicle.

She watched with wide eyes as the blob then seemed to merge with the motorcycle. Soon enough, there wasn't a surface on the bike that wasn't black and green.

Those were the villain's last thoughts before the bike moved on its own and threw her off so fast that she couldn't do anything in time. She landed on the ground right in front of a policeman who didn't hesitate to grab her wrists and cuff her.

Upgrade, now in complete control of the motorcycle, turned to the renaming two women, glaring at them with his one eye.

The biker in yellow seemed to tense up, whereas Rojo was unfazed. The redhead scoffed and created another blade between her fingers. Wordlessly, she raised her blade and gestured towards Upgrade. Her remaining member picked up on the silent order, beginning to charge at the hero with her motorecycle. As she did so, the yellow villain raised her hand. From it, Upgrade watched as a fireball appeared, probably due to the women's quirk, and was thrown towards him.

With such a simple attack and the speed of his motorcycle body, Upgrade dodged it with ease, swerving to the side and letting the fireball hit a nearby streetlight.

Not giving the villain another chance to attack, the Galvanic Mechamorph struck first and, like he had with many other vehicles, created a turret on the seat of his motorcycle body.

As easily as he moved his hand, Upgrade directed the turret towards the wheel of the incoming bike and, with another thought, fired a laser at it.

The women in yellow armour screamed as she was launched from her smoking motorbike and towards the hard, concrete pavement. Both Upgrade and Rojo stared as the women didn't seem to move as muscle afterwards, the former hoping he didn't kill her.

The latter, on the other hand, shrugged. "Well, as the old saying goes," said Rojo as she gave her foe an evil grin. "If you want something done right, do it yourself-"

Pew!

A laser from Upgrade's eye took her entirely by surprise as her chest caught it. The concussive beam sent her flying off her bike and onto the road, the impact making her be grateful for he armour.

As Rojo winced and got up, she saw the surface of the upgraded motorbike recede form the vehicle. It then reformed into a tall and vaguely humanoid figure with long arms and a single green eye with green and black lines all over his body.

"Alright then," said the transformed teen with a robotic tone. "Let's settle this."

If Rojo was angry before, she was outraged now. "This little fucker isn't taking me seriously!" was her last thought as she created knives all over her hands and charged.

She could have saved her breath.

Upgrade simply folded his arms and stood as the knives raked at his chest and neck, his metal body rendering the knives useless against him. Rojo was stunned: of all the times for her favourite weapons to do absolute squat to something, it had to be now and with the target of her revenge!

Upgrade, refusing to give the American another second, raised his right hand hands, which then morphed into a massive hammer, and brought it down upon her head.

Watching Rojo slump and fall upon the ground, Upgrade then turned to the police officers present and gestured to the fallen villains. "Well, they're all yours officers-"

"Gah!"

The feminine scream made Uprgade jump, he turned around to see the villain in yellow armour, the one he believed to have been unconscious, get tazed by a stranger.

The stranger appeared to be a young man with cyan hair and rather pale skin. Upgrade noticed the man's red eyes look down on the women as he held an odd device in his hands. It looked like something out of a sci-if movie, but judging by its effects, it was no prop.

That wasn't the only thing off about the man, he wore white armoured suit with red circles over his collarbone and belt. Noticing the puzzled looks the vigilante and police were giving him, the man chuckled and spoke. "Sorry about that, she looked as though she was about to fire something at you, kid. I couldn't let that happen." Waving his hand at the teen, he continued to speak. "I wanted to talk to you in a... calmer environment, but this will do."

Upgrade tapped the symbol on his chest, reverting him back to a cautious Izuku Midoriya. He had never seen this man before in his life and couldn't take any chances.

"Judging by your… uniform, you're either another hero or some kind of law enforcer," said Izuku as he took in the appearance of the man, a tense look on his face. "Who are you?"

The man held up his placatingly, a smile on his face. "Hey, relax kid. I'm Lieutenant Tenko Shimura. I represent the Plumbers."

OOOOOOOOOO

For someone who claimed to be a representative for toilet repairmen, Tenko had somehow convinced the police to allow Izuku to come with him. He had merely taken some papers and showed it to them. Izuku didn't see what was on them, but he had made out whispers of:

"The Prime Minister?"

"This is big..."

When cough interrupted his thoughts, Izuku turned and saw Tenko give him a smile as he drove the car they were in. The windows were shaded, preventing the greenette from seeing where they were going, much to his dismay.

Tenko, however, seemed unfazed as he viewed a screen on his dashboard, detailing a route to somewhere. So far, the man had deflected all of Izuku's questions, only requesting that he be patient and wait until they have arrived at their destination.

"I have to be careful, I'm not sure what-"

"I AM HERE! I AM HERE!"

Groaning at his ringtone for the second time that day, Izuku quickly declined the call. Having seen that it was Izumi who had called him again, he resisted the urge to sigh at his sister. He loved his little sister, but it wasn't the time for it.

Hearing a chuckle from in front of him, Izuku raised his head and saw the the pale man grin through the mirror. "So, I bet you're a big All Might fan, eh?"

"... When I was younger, yes. Now, you could say I'm more of a casual fan"

"Yeah, I get that."

Just then, the car had stopped. Izuku, once again, tensed up as Tenko said. "Well, we're here."

Punching a button on his dashboard, Izuku could then feel the vehicle move downwards, as though they were in an elevator. After ten seconds, Tenko pressed another button and all of the doors were unlocked. After that, the Lieutenant rubbed a hand thought his cyan hair and opened the door. Looking back at his passenger, Tenko Shimura gave him yet another smile.

"Izuku Midoriya, welcome to the base of the Plumbers."

Stepping outside, Izuku was stunned for yet another moment in his wild life. The greenette had been inside both a spaceship and a police station on a field trip. The place he was in appeared to be a fusion of both. He looked up and saw the the base was incredibly large, reaching about 20 stories tall.

Another surprise to Izuku was the presence of aliens. Some were criminals, given how they were handcuffed. However, even more wore the same suit that Tenko wore and conversed with humans who wore it as well.

Tenko, seeing his boss approach, nudged Izuku to get his attention. The teen then turned his head and saw the biggest surprise he had to that day.

"Good afternoon, Magister Midoriya."

Walking toward them was none other than his own mother, Inko Midoriya. Though she was chubby, the women wore a sullen look and carried herself impressively. She wore the same suit as the rest of the personnel present and was on the phone talking with someone.

"Alright, tell the Lenopans I'll deal with the problem afterwards, there's something I must handle first."

Seeing her gaze land on him, Izuku gathered his thoughts as his mother put her phone down and, on her aged face, put on a soft smile.

"I suppose we have much to discuss, Izuku."

Izuku clenched his teeth, this was going to be a VERY interesting conversation. Giving her a small nod, Izuku replied. "Yes, I gue

"I AM HERE! I AM HERE!"

As Tenko and Inko gave him playful and quizzical looks respectively, Izuku took out his phone once more.

This time, he did sigh as he saw the caller ID was, once again, Izumi's.

When his finger found itself on the accept button, Izuku raised his phone to his ear and spoke with quiet fury. "Izumi, this had better be important-"

His sentence was cut off as the stream of words came from his phone. Izumi was speaking so loud that the vigilante had to hold his phone slightly away from his ear. Inko and Tenko watched with slight amusement, picking up some of the words Izumi was saying.

"... Pax..."

"Pax? He's a bother, but harmless. How did you meet him?"

"We just... Hokestar..."

"Professor Hokestar? He didn't try to-"

Izuku gasped he heard the explanation that his sister was giving him, his sudden silence puzzling his mother and Tenko.

It was the next sentence that struck fear into the hearts of every single Plumber that was nearby.

"WHY ON EARTH DO YOU HAVE A SCREEGIT?!"

OOOOOOOOO

Notes:

1. Cannonbolt here is identical to his appearance in UAF, but he does have the stripe on his chest that was present in the OS and Omniverse. He has his Omniverse voice.

2. Upgrade here resembles his Omniverse appearance but with the Omnitrix symbol on his chest rather than on his eye. Like Ben, he sounds like Izuku but with that robotic filter.

3. As for Toshinori/Chrono Spanner, imagine Izuku with brown hair and a little lock in the middle of his forehead. A little detail you may have noticed is the fact that he has six fingers on each hand, this was more of a genetic mutation instead of part of his quirk of telekinesis. For a voice actor, I would have to go with Johnny Young Bosch.

4. Hikaru Iro is an original character created for this fic. Like Toshinori, she's from the future. Apart from her magic, she had a light-based quirk. Her ideal voice actor would have be Cherami Leigh.

5. Please watch this, sorry in advance: watch?v=dQw4w9WgXcQ

That's all for now. Here's the preview for the next chapter.

Next Time on My Hero Academia: Hero Time

"Are you sure about this Izumi?" asked Ochaco cautiously. "I'm sure that there's a reason Deku wouldn't answer your call."

The greenette preteen shrugged and grinned. "Where else could he be? He normally goes to Undertown every now and then. We could surprise him for once!"

Just as Izumi and Jun were admiring their new Sumo Slammers trading cards, a yelp from Ochaco alerted them to a looming presence behind them. As they turned around, hands raised to defend themselves, the duo were surprised at what they saw.

An alien that looks just like Wildvine and had clothing that reminded Jun about the hippies he learnt about in history lessons.

"So, you guys said you're friends with Midoriya? I've been looking for him."
