Old Reviews
dannyrockon122: I have some ideas for those aliens you have mentioned and Albedo will be in this story eventually.
lucarioDN: All will be revealed in time, just wait a longer.
God of Hentai: I wouldn't say Izuku has mastered the Omnitrix, he does not have the Master Control after all. Also, if he does get One For All, he will still face the problems he had at the start.
MIKE202303: Thanks!
TheOKWriter: Someone else, who will be revealed in time, told Izuku about the quick-switch function. Besides, he's had the Omnitrix for four years, he was bound to figure it out sooner or later. As for Vilgax, there's a reason why he took that long to find the Omnitrix.
Aztec 13: Just you wait. There's more to come! Also, Izuku will still go to U.A. in this story.
Amit Barabi: At this point, Undertown is not public knowledge. People have just found out about aliens and Izuku's secret so far. Next, I don't have any plans for Jun being related to All For One, but that's not a bad idea. Also, thanks for the heads up again.
Guest: Izuku will unlock more aliens in the future. There are no plans for the ultimate aliens though. As for the Antitrix and Nemetrix, I have plans for them.
sonic: Thanks for your review!
CCSakuraforever: ¡Gracias por disfrutar mi historia!
Gamelover41592: Thank you for giving my story a chance. As for the police situation, read more of this story to find out.
Morgoth995: I am considering Izuku getting OFA, but later on in the story, but there are no current plans to add the Ultimate Forms here.
New Reviews
Gamelover41592: Thank you! Izuku still wants to be a hero, but he fought corrupt pros over the years, so he can't bring himself to completely trust the law anymore. This version prefers to do heroics without being bogged down by legality and bureaucracy.
Amit Barabi: Thanks! I know it's bad form to praise your own work, but I really liked how I wrote the new Chapter 3
Chronos0305: Glad to see you like it! Don't you worry, both Big Chill and Wildmutt shall one day be in this story.
Ben 10 Arrow fan: If only…
Dinobot: You'll see Shoto's thoughts in a side chapter. As for using his fire, it'll go a lot differently due to this Izuku's mindset
I'm Hellboy: Sorry, but in this universe, All For One is dead as you will learn soon enough.
afton: Thanks!
Magi: Only shapeshifters like Lenopans, humanoid aliens with ID masks and alien hybrids live outside of Undertown
Sting.X1: Hikaru is another hero from the future and Toshinori's girlfriend.
RANGER1863: ¡Gracias, espero que disfrutes este capítulo!
Nothing else to say. Let's begin!
Chapter 4: Discovery
OOOOOOOOOO
When Izuku finally saw his apartment after taking down that giant robot, all four of his eyes as Stinkfly widened at the sight of, not a crowd of news crews, but absolutely no one there. It came as a surprise as he had just defeated an alien robot, people would demand answers and, seeing how he's possibly seen as "the alien hero", come to him for them.
The absence of such people at his apartment was suspicious. Izuku doubted that his mother, while fearsome when she was angry as he knew from experience, could make them all back off.
"Never mind that now, I have some tasks to do."
OOOOOOOOOO
Despite Grey Matter's small stature, Izuku always enjoyed transforming into him due to his intelligence. His smallest alien form may not be suitable for straight-up combat, but he always felt that his intelligence would be handy, so far, he hasn't been disappointed. As Grey Matter, he was able to design the blueprints for his equipment and think up strategies for dealing with villains.
In this particular moment, he was in the process of writing an application on his phone that would find out the true identity of HeroMastermind, the person behind the reveal of his secret. This particular program should be able to use HeroMastermind's IP address to help track them down. The teen had created a prototype of this two years ago and expected results the following morning.
Now that his first goal was finished, he got started on his secondary goal to repair the weapon systems on the 10-Drone that was situated on his desk. It had accidentally crashed into a building just a few days before, it could still fly and use its camera and flashlight, but it couldn't activate any of its armaments. A box of spare parts by his side, Grey Matter adjusted and fiddled with the inner workings of the 10-Drone, his amazing intellect and small, dexterous fingers helping him in this endeavor.
Just then, the Galvan could hear a knock could his door. "Come in," said Grey Matter as he tinkered with a circuit board.
Through the door came his sister, Izumi Midoriya, wearing a concerned expression on her face. "Mom says that you've been in your room for too long, what're you doing anyway? And why are you Grey Matter?"
Izumi's transformed brother poked his head over the 10-Drone as he said, "Well, as you can see, I required Grey Matter's heightened intellect for two purposes. First, to create a method of which to find out the location and, subsequently, identity of the person who revealed my powers to the word. Second, to repair the weapons system of the 10-Drone."
Managing to follow his words, Izumi then sat down on his bed. "Okay then, it's time for dinner. Wanna come? I bet you still get hungry as an alien."
Letting out a sigh, Grey Matter decided to take a break: the 10-Drone's weapons were almost repaired and it was about time for him to transform back into a human.
"Very well," said the Galvan as he walked over to the right side of his deck and climbed down. Once he was on the floor, the Omnitrix symbol on his back started to flash with red light. A second later, Grey Matter was gone and Izuku Midoriya was there, ready to eat.
OOOOOOOOOO
Dipping a piece of mackerel in soy sauce with chopsticks, Izuku Midoriya began to wonder who could have sent that robot? One of his old enemies? Could it have been Vulkanus? That crime boss definitely had enough money for it. Then again, there was the chance that it was either an isolated incident or a sign of something bigger.
Then, Izuku felt his sister nudge his right shoulder. When he looked up, Izumi gestured towards their television, which was currently showing the news. "Panic and confusion. That was the scene at downtown Musutafu earlier on, when a giant robot that appeared to be of extraterrestrial origin fell out of the sky and rampaged, creating massive destruction and fires. While doing so, it took a hostage and managed to keep several heroes at bay. The robot took a hostage named Katsuki Bakugo, a junior high student, who unsuccessfully tried to escape."
The news then showed a picture of himself at the side while the reporter at the scene continued to talk. "Later on, the teen vigilante Izuku Midoriya stepped in, transforming into the fiery vigilante known as Heatblast and, while fighting the robot, transformed again into Diamondhead. Witnesses say the second form was the one to finally defeat the mechanical menace. Now, we'll hear what civilians present at the scene have to say."
After that, the screen showed an old man who looked like a stereotypical office worker and said, "That kid just ran through the crowd, distracted that gigantic robot and transformed into that fiery form of his. What was it called again? Heatblast? Anyway, he flew up in he air and got that hostage away from the robot. It was pretty impressive."
The video then changed to that of a little girl. "He was hit by the robot, but then he got back up and transformed into the shiny crystal hero and destroyed that alien machine!" After that sentence, a voiceover could be heard saying, "Now, let's find out how the pro heroes at the scene feel about Izuku Midoriya."
Who the Midoriya family could see next was none other than Kamui Woods, a microphone right in front of his face. "I don't approve of his vigilantism, but I must admit, he handled the situation well enough. Izuku Midoriya defeated that robot when none of us could."
The camera then switched to Death Arms with his arms crossed and wearing a frown on his face. "When the kid blasted apart the robot with its own laser, it caused some damage to the surrounding buildings. Honestly, I wished he was a little more careful. Besides, he couldn't save Hitchcock Doodle, could he?"
After Death Arms' statement, Izuku became downcast, he knew he couldn't save everyone, but still…
Then, the camera then showed the hostage of the incident, an ash blonde teenager in a school uniform. being tended to by paramedics. "This is Katsuki Bakugo, a student at Aldera Junior High. He was grabbed by the mechanical menace from earlier and rescued by Izuku-"
The reporter was cut off by Katsuki pushing past his paramedics and power walking over to her as he angrily shouted, "I DIDN'T NEED DEKU'S HELP, I WOULD'VE GOTTEN AWAY FROM THAT GIANT TIN CAN SOON ENOUGH!" Pointing to the camera, he continued his rant. "IF YOU'RE WATCHING THIS DEKU, LISTEN UP! DON'T YOU DARE LOOK DOWN ON ME!" Katsuki was interrupted when medical personnel grabbed him and dragged him away from the camera.
"Sheesh, what a dick," muttered Izumi as she fiddled with a piece of mackerel.
Inko, then looked up from her meal and said with a small glare, "Izumi, watch your language." Upon hearing her mother, Izumi simply sighed and complied. This exchange was ignored by Izuku, who was deep in his thoughts. He began to think whether or not the other students of Aldera Junior High would react differently to him. The news of his recent actions, combined with the knowledge of his previous heroic actions, would most likely cause them to start treating him as another hero.
He knew none of them would truly mean it.
Almost everyone he had met in his everyday life treated him and, by association, Izumi, Jun and Uraraka like trash before. The greenette knew that his circle of trust would have to be small to prevent disappointment.
It had to be.
OOOOOOOOOO
Today seemed to be one thing after another. First, Izumi and I had to leave for school through the window because of the press being right outside our door. Next, a villain with a Gigantification quirk had to be stopped by me as Stinkfly before he could do any more harm to infrastructure and civilians.
Taking a deep breath and collecting his thoughts, Izuku moved his pen once more across the page of his journal, recording his experiences of the day.
As predicted, Katsuki threw a temper tantrum regarding me "lying to him" over the past few years. I have already stated this in this journal multiple times, but I'm glad I was able to see what a terrible person he was. In another world, I would've been scared half to death by how angry he was today.
Just then, Izuku heard a knock at his door which opened to reveal his mother. Inko yawned and said, "Izuku, I thought we agreed on a certain sleep schedule?"
"Mom, I'm a little busy with-"
"Teen vigilante or not, you're still a growing boy and need plenty of rest."
"I can-"
"Izuku…"
With the tone his mother took, Izuku knew that there was no point in arguing. He's face down supposed sorcerers and crime lords, but he still feared the wrath of Inko Midoriya.
"Fine, goodnight Mom."
OOOOOOOOOO
The next morning, Izumi and Inko woke up to find Izuku gone. The two of them entered the teen's room only to find the window open and a note on his desk.
Went to handle bank robbery, will get breakfast at convenience store.
Inko let out a sigh, this certainly wasn't the first time Izuku went for a morning jaunt, but she couldn't help worrying about her son every time he went on a patrol.
Hearing a yawn behind her, Inko turned to see her daughter rub her eye. "Man, I'll never understand how 'Zuku can be such a morning person."
"Izumi, we both know that Izuku has… problems staying put now." It was true, her son was on edge often and was always on the lookout for crime, which led to a whole host of problems.
"In the meantime, get out of your pajama, Izumi. You have to get yourself ready for the day."
After seeing her daughter away and into the bathroom, Inko took out her phone and, with a determined look on her face, called her right hand man.
"Shimura, it's time."
OOOOOOOOOO
Munching on a rice ball, Izuku enjoyed the view on top of one of the many skyscrapers in Musutafu City. Taking care of the bank robbery was easier than he had expected.
The villain, who had the ability to manipulate metal with a touch, was handled with Diamondhead covering the area with crystal and socking him in the jaw before the red-headed could gather his bearings. Fortunately, the Petrosapien managed to leave before he could get bothered by law enforcement or, worse, the press.
Izuku was still trying to figure out what to do next, the technology of the alien robot that he had fought the previous day would be evidence enough for extraterrestrial life. Not only that, he needed to make arrangements for the possibility that any of his old foes would come for his family or the little friends he has or if any new villains want to prove their mettle by taking him on.
Chuff-chuff-chuff-chuff
Hearing a familiar sound of a helicopter, Izuku turned around to see a news chopper with a J News logo behind him, the cameraman onboard already filming him. Groaning in annoyance, the greenette, bag in one hand, got up and walked over to the edge of the roof.
Giving them a salute and checking the Omnitrix, the teen then jumped off the roof, much to shock of the news crew and viewers.
Much to their relief, there was a flash of green light, followed by a giant insect flying away from the chopper. With a motion from the reporter, the pilot began to pursue Stinkfly while the cameraman kept his camera on the vigilante.
Holding his backpack in his arms, Stinkfly pivoted two of his eyes toward his rear, glaring at his pursuer. "Vultures," thought the hero, his mind wandering to hatching an escape plan.
Making things worse, another chopper, one from Channel 7, seemed to join in on the chase for an interview with the hero, who groaned at the sight.
Stinkfly then flew over the morning traffic. The sight of the hottest thing in the news led people to point and talk about his appearance.
"Looks, it's a bird!"
"No, sweetie. It's some kind of bug."
"Is that a plane?"
"No, Grandma, it's that alien kid! You have to get new glasses!"
Ignoring the chatter of the crowd, Stinkfly did some aerial acrobatics in an attempt to lose the choppers. His efforts were for naught as the helicopter pilots proved to be tenacious. They turned so sharply to follow Stinkfly that he wondered if the pilots were underpaid.
Just then, another news helicopter appeared out of a corner. Stinkfly, with all the speed and momentum he had, couldn't change his direction. All he could do was to brace for impact as…
OOOOOOOOOO
"… I then rammed into that helicopter head first."
Ochaco winced upon hearing about her friend's "morning jaunt". Izuku had arrived at the school as Stinkfly, having flown down rather unsteadily as he was still shaken from the impact. His sister and friends immediately bombarded him with questions regarding his well-being, all of which he shrugged off. Eventually, the teen caved in around lunch and recount the events of his morning to the trio. Izumi, Jun and Ochaco had listened to how Izuku had stopped the bank robbery and were currently listening how he had escaped the press.
"And then what happened, Deku?"
"Well, while the helicopters were trying not to ram into each other, I managed to hide in a passing car carrier under a bridge," explained Izuku as he finished off the lunch that his sister had brought for him. "After I made sure that I'd lost them, I just flew off and came here."
Izumi, having listened the story with her full interest, let out a sigh. "Man, I know you don't really like all of this attention, but it just sounds so exciting, 'Zuku!"
Izuku scoffed in response, his sister rarely took things as serious as they truly were. "Yeah, racing helicopters just after breakfast is just what I wanted."
Pouting, Izumi was about to say more when the lunch bell rang, signalling the group to pack up and head off to their respective classes.
Izuku and Ochaco's classmates seemed to be walking on eggshells around them. The former's cynically noted it was simply because they were afraid of any retribution for the years of torment he had suffered at their hands.
Speaking of torment, his former bully glared daggers at him the entire day. Katsuki was acting just as Izuku had expected: his rescue of the former would be be seen by the blonde as looking down on him.
"Just like that incident at the stream when we were kids."
It was after the last period that Ochaco, Izumi and Jun fully understood Izuku's concerns about the press when they laid their eyes upon a rather large crowd and commotion right in front of the school gates.
Tapping the brunette's shoulder, Izumi whispered, "Can you float us all, 'Chako? Or better yet, these guys?"
Seeing the older girl shake her head, Izumi resigned to wading through the crowd until she felt a familiar hand pat her shoulder. She turned to see Izuku mouth "I've got a plan" before he bravely ventured toward the press and assorted weirdos. The moment he did so, questions were shot at him.
"Izuku Midoriya! What are your thoughts on potential alien invasion?!"
"Have you achieved first contact with extraterrestrial life?!"
"Are alien babes sexy?!"
Hearing the many questions that cam from crowd, Izuku simply ignored them as he calculated the best method of escape. "Time for me, as All Might would do, to take refuge in audacity."
"Izuku Midoriya, do you have a statement?"
Hearing the last question, the greenette took a microphone that was offered to him.
"I do."
With a serious look, he activated the Omnitrix and dramatically raised his right arm, throwing away the microphone in the process.
"IT'S HERO TIME!"
Slamming the watch's dial, the being standing there was no longer Izuku Midoriya, instead, it was a muscular, red alien around 3.7 metres tall with massive arms and four green eyes.
The transformation triggered a wave of photo taking. The camera flashes were so bright that they could blinded Four Arms as he closed all four of his eyes. Despite this, he knew he could still continue the rest of his escape plan.
With a good grip on his backpack and powerful leg muscles, the Tetramand jumped over the crowd and onto the roof of a nearby building.
It took five seconds for the press to realize that they've missed the chance for an interview, causing them to promptly disperse and allowing the students the freedom to leave
On a roof, Four Arms noted all of this with a satisfied nod and prepared to start a patrol.
At least, until he got an alert on his phone for a special task.
OOOOOOOOOO
Taking a deep breath, Izuku held up his phone which showed notification that said "TARGET FOUND". His tracking program had found HeroMastermind's place, a warehouse located downtown and the greenette was currently right in front of it.
Drawing from his years of experience, Izuku knew warehouses had hiding spots and were ripe for ambushes. "So, I'll just ambush whoever they are instead."
With skills honed by years of practice and conveniently placed platforms, Izuku managed to reach and climb through a window into the upper area of the warehouse. Softly moving towards the railing, the greenette looked down to see a hooded figure overlooking a computer. The figure's back was facing him, so Izuku couldnt see they're facial features.
The vigilante did note that HeroMastermind only had a handgun on his table. It seems too odd, why would he bring such little protection?
"I see that you've come."
Hearing a voice that came out of nowhere, Izuku turned sharply to see a white figure levitating in the air, a green glow surrounding him. Upon closer inspection, the greenette could see that the figure's armor looked high-tech and that he wore a green scarf. Judging by the voice, the being was male.
The being wave his hand towards the lower level and, before Izuku's eyes, the thing he originally thought was HeroMastermind was taken apart with a green sheen covering them, revealing several pieces of trash and junk hidden under the sweater.
"Ah yes, the classic dummy trick," said the telekinetic person as he lowered his hand, causing the green glow around the objects to disappears and letting them fall.
Floating downwards to a tense Izuku and holding out his hand, the being spoke once more, "It is an honour to meet you in person, Izuku Midoriya. You may call me Chrono Spanner."
OOOOOOOOOO
Notes:
1. Grey Matter has his Omniverse design and voice.
2. Four Arms in this story is a mix of his Ultimate Alien and Omniverse designs. His head is that of his UA head but without the ponytail. On the other hand, the rest of his body are that of his Omniverse design. However, his legs aren't as thin, being a little more muscular. He's has his Omniverse clothing, including the belt. His Omnitrix symbol is located on his chest.
3. I hope I got that helicopter sound effect right, there were several to choose from according to Google.
4. In a tiny detail above in the warehouse scene, Izuku has picked up parkour skills to the extent where he could be considered passable.
5. I've changed the identity of HeroMastermind from Jimmy Jones to Spanner as, after giving it a lot of thought, I wouldn't really use Jimmy much whereas Spanner would appear every now and then.
Next Time on My Hero Academia: Hero Time
"You can't defeat all of us, kid!" proclaimed Rojo as one of her henchwomen 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!"
"Judging by your… uniform, you're not ordinary law enforcement," 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 of the Plumbers."
