"A-alternate dimensions?!" Momo repeated, completely stunned this conversation had taken the turn it had. "I… It's possible I guess. Even before aliens they're were quirks allowing people to drop items in pocket dimensions, but whole alternate ones?"

"If it's hard to believe…" Gwen began, reaching into her pocket and pulling out a book. The raven haired girl took it and opened it up, eyes widening as she took in illustrations of Izuku's aliens, with some minor differences here and there. "XLR8, one of the fastest aliens in the Omnitrix, the balls of his feet let him control the friction of the ground beneath him to an extent. Humungousaur, a complete powerhouse of an alien able to punch mountains apart if he really wants to and grow up to sixty feet in size, power growing with each increase. Heatblast, a body made completely of fire, allowing him pyrokinesis and the ability to fly, as well as durability able to withstand being thrown through multiple buildings."

"Those… those aren't-"

"Midoriya's names for them? No they aren't. They're what they are called in my dimension." Gwen said casually, taking a sip of her tea while the creation teen felt her mind implode. "Midoriya doesn't have the Omnitrix in my dimension, someone else does."

"H-huh?"

"Benjamin Kirby Tennyson, my cousin." She revealed, and Yaoyorouzu's brain officially stopped working, getting an amused snort from the woman. "You ok, Yaoyorouzu?"

"S-sorry…. I'm… your…." Shaking her head, the creation teen went very slowly. "You are… from a different dimension?"

"Yup. Let me guess, I'm insane?"

"N-No! I'm not saying that. I mean If aliens are real then it's not too hard to think some other things might be real but… Why did you bring me here then? And why are you here?" Momo pondered, cocking her head to the side and making the red head let out a cute giggle.

"Well, you remind me of myself actually. I did send a request to him as well but I didn't think he'd take it, I think I know exactly who he's with now." The pro's tone turned more serious instantly, as she pushed out her hand a purple form of energy released, creating something of a projection. "The Plumbers."

"Yes, they want to teach him how to properly handle alien life, they said." The raven haired teen nodded, and a fire seemed to be lit at that revelation in Gwen's eyes.

"Then we have no time to lose, your training begins… NOW!" The second the red head shouted that, she threw a disc of purple energy right at the tall teen, who…. froze up.

It dissipated just before it hit and Gwendolyn sighed.

"First things first, we need to fix the problem you had at the sports festival. Your reaction time, and overthinking."

"My… overthinking?"

"Just between you and me, I didn't become a pro the normal way. I've been fighting aliens and criminal since I was ten years old, and one of the first things I had to learn… over-thinking is your worst enemy."

Another purple energy disc came flying at Momo, and her eyes widened again but this time, very barely at the last moment she managed to create part of a shield, before the disc exploded and sent the teen onto her butt.

"You worry about how you're going to do something, and you get flooded with ideas. You need to learn to pick one without hesitation."

Another disc, another shield just a fraction of a second faster. This time the shield stayed up however and Momo grinned, thinking she'd already began to improve.

"Finally, you need to learn to stop being so rigid with your quirk. So predictable."

The raven haired teen looked down at that statement and saw a tiny purple ball of energy attached to the shield, that exploded in her face.

It was going to be a long day.

For Midoirya, day one of his internships had been fine after the incident. Once he'd seen his room, he'd been lead to the gym area where he had been taught some basic self-defence by Norio while waiting on the magister.

His reasoning had been to help him be just that little bit safer in human form. The leader of the plumbers had eventually came and they had spent some time discussing what aliens Izuku had so they could plan ahead.

It had been a slow but enjoyable day. Today on the other hand….

"AAHHHHHHH!" Chiller screamed as volts coursed through him, before suddenly they stopped and he dropped to the ground, breathing heavily as he turned back into Midoriya.

"And that is your natural weakness as a Necrofriggian." Homura said, as Norio marked off the final of the aliens on list. "We're done now, sorry about putting you through all that."

"It's… it's fine…" He breathed out. "I asked for it anyways…"

They had decided to get the most unpleasant lesson out of the way first, learning the true weaknesses of each of his aliens, the natural ones he should avoid. For all his time with them, he'd never actually found out what was bad for a lot of them.

Some like Blink where obvious, uneven grounds and such that could trip him up could really do damage and he didn't have the body to resist heavy hitters.

Others like Chiller had been more surprising. Midoriya had always though nothing could touch him when he was intangible but it turned out he was wrong, electricity was still a danger and so was anyone else who possessed similar abilities as they'd cancel each other out.

And he tried to use the alien with an electricity weakness against an alien known for using electricity. Go him.

"Alright, next up I think we should have you face off against our best plumbers, each with a different alien." The Magister said, walking over to the console. "That way-"

"ALERT! ALERT! ALERT!"

All eyes turned to the computer, as the words it was crying out also flashed up in red text. Then a video feed appeared, and Midoriya's breath hitched as he saw Nomu's destroying Hosu city.

"Those aren't aliens…" He muttered, eyes wide with horror. "Why are there nomu's…."

"Good question, but that's the heroes priority kid. Look!" Homura pointed out, and the video feed zoomed in on the alien from before running from the heroes down the street, a red four armed muscular alien beside them. "That must be an accomplice, they're making an escape! We have to capture them before they get away. Midoriya-"

A green flash took over the room, and the magister turned to see Blink beside him.

"Don't even try to stop me coming along, not with Nomu out there." The teen said in his raspy voice, and the man nodded with a sigh.

"Fine, just make sure that you don't get in the way of another capture net. Come on, get a team out there!"

With that, they all turned to leave. As Izuku did, his eyes moved at an imperceptible speed while he did a quick headcount of all the employee's.

Because something had been irritating him this whole time and now he'd finally figured it out.

The plumbers knew about aliens, could help them and employee them when they weren't criminals….

So why was every plumber in this room a human?

Completely unaware of the chaos at the moment, Gwen and Momo were onto their second day of training and amazingly the raven haired girl was already beginning to make improvements.

Gwen easily spotted the creation girl's weaknesses and was even helping her adjust to new ways of using her power. In the red head's words:

"If you keep using the same shield and pole trick every time, you'll always be completely obvious to your opponents."

So now she was using some new tricks the woman had left her with, specifically more physical recreations of the woman's 'magic' attacks.

In place of energy discs, Momo was throwing metal discs from her body with miniature IED's attached. The shield dropped as the third of them landed, and while the pro's guard was down, the raven haired teen tried to copy another trick.

Namely, she relied on how her quirk worked to manipulate the material she was making and capture the pro in metal casing. It drained her completely but it worked!

For all of five seconds. A purple light shot out and the metal broke, once again throwing the teen back.

"Not bad, Yaoyo." Gwen compliments, having taken to a nickname for ease. "Still, just copying me isn't going to exactly improve you a lot, considering there's only so much you can do."

"So what do you recommend then?"

"That you figure it out yourself." The red head suggested, but in a kindly way with a smile. "You're doing really good, but you can't rely on others to learn when it comes to fighting. No one knows you like you do."

"But… I'm just-"

"An incredibly talented girl with a powerful…power? Yes, yes you are." The woman assured her. "Think about your power. Really think, what do you know that no one has seen about it? What is something you think's possible but never tried?"

"Well-"

BOOM!

Both jumped up at the sound of an explosion, running to the window and gasping as they saw fire and smoke rising.

"Guess we're up then, Yaoyo!"

"Wait, what? But I'm just an intern. I've not even done basic a patrols yet."

Gwen just smirked. "Trust me, if you've got a heroes heart then you wouldn't be able to stay away much longer. Especially cause I bet your boyfriend is going to be in the middle of this all very soon."

"Izuku?! Why would he-"

A voice cut them off and they looked down to see two aliens running away, one with a pitch black sleek body and one with a bulky red one that had four muscular arms.

"Come on, Plum! We aren't going to get a better chance to escape!" The black alien called, getting an affirmative grunt from the red one.

BWOOSH!

All to suddenly they were stopped by a familiar blue and black alien, and Momo's eyes widened.

"Hold it right there!" He called out in his raspy voice, and immediately had to dodge an energy blast from the black one. "Not getting away this time!"

"Come on, Yaoyo!" Gwen called, getting the raven haired teen's attention and making her gasp when she saw the woman's normal form replaced with a purple body that had glowing vibrant pink energy in place of hair. "We gotta get down there and help them!"

"Right! Izuku will-"

"Not Izuku! We need to help the aliens."

Momo froze.

"What?"

"They're innocent. Completely innocent, but he doesn't know that, and he's about to send them right into hell!"

And with that, Gwen took off again.

"JUST LEAVE US ALONE YOU BASTARD!" The conductoid screamed, throwing more and more blasts out. Quick as lightning Blink dodged all of them with ease, the plumbers still on their way to them, having let him go ahead to distract them.

Suddenly, he was behind the black alien and delivered a swift kick to their head, before suddenly he was picked up by the other alien.

"Leave her alone, you scumbag!" The four armed alien shouted, kneeing him in the stomach and throwing him across the street. The greenette slowly and painfully tapped his symbol, turning back to normal.

He looked up to see the alien beginning to stomp towards him but a light zap stopped him.

"We need to go, Plum!"

"I don't…. think so…" Midoriya muttered, as the Omnitrix charged up, fortunately having used almost no energy in the short time he'd been Blink. 'Know now not to use Chiller. Super strength and electricity so….'

He made his selection and in a flash of green, he was replaced by Crystalize, glaring at his opponents. Not giving them a chance to breathe, he ran forward as his arms shifted into blades and aimed right for plum, who readies himself to fight.

"TAKE THIS!"

CLANG!

Midoriya blinked in surprise, as a metal wall suddenly got in his way before a ball of purple energy hit him square in the chest and threw him back.

"Careful!" he heard the familiar voice of Momo call out. "Don't hurt him."

"Sorry, still needed to get him back though." Another voice said and he looked to see a red head with his maybe-girlfriend.

"Yaomomo?" He asked confused, getting up. "What are you doing? They're villains."

"No, they're-"

Before Gwen could finish, Plum seemed to have decided he didn't care their intentions and jumped over, punching Midoriya over and over before he finally managed to form a shield.

"STOP IT, BOTH OF YOU!" Gwen called out, but neither listened. Plum because he didn't want to and Izuku because he didn't have a choice, as more blows rained down on him.

Finally, the four armed alien lifted the teen up by the throat, only flinching lightly when Gwen sent an energy disc at him. With a free hand he tapped the watch, like he watched the teen do a minute ago and now the human form of Izuku was in his grasp.

"We told you to leave us alone."

"Plum, don't!" The conductoid called out, blasting ahead. All three girls tried to get to them before it was too late but the black alien was the fastest, landing on the red aliens back.

"New DNA sample's acquired."

Another flash blinded them all once more, and suddenly there was a second red alien in their numbers, who broke the grasp on him immediately.

"Izuku, wait! Don't fight!" Momo called, and the greenette would listen...

If he wasn't still on the defensive because Plum refused to let up.

"I would, but you know he's not exactly letting me stop!"

"LIAR! YOU JUST WANT TO HURT US!"

"What- UGH!" Midoriya froze at that accusation before he was knocked back, and let out a growl. "Sorry Momo, but he won't stop. If he wants to wrestle… then we're gonna wrestle."

"THAT'S ENOUGH!" The black alien called out once more, grabbing everyone's attention as she aimed her fingers at both the four armed aliens. "EVERYONE STOPS RIGHT NOW OR I BLAST YOU ALL TO KINGDOM COME!"

"Tessa, what are you doing?! He's a plumber!" Plum asked, finally stopping. "You know what he'll do to us."

"T-Tessa?" Midoriya asked, as his throat went dry. "You… you have a name?"

"Of course I have a name, you idiot! Not that you care." She grounded out, and suddenly, the greenette transformed back.

...We don't know it's name.

He met her eye with an unreadable expression.

"What…. What was your crime?"

"Huh?"

"The plumbers said you were a criminal. They also said they didn't know your name. What was your crime?"

"NOTHING! I DIDN'T DO ANYTHING!" She said, clearly getting annoyed.

"She's telling the truth." Gwen interrupted, turning back to normal herself. "I know who the plumbers are. They aren't going to have told someone like you the truth."

"…." Midoriya sighed, looking up to alien. "What will you do? If I stop now, if I let you run, what will you do?"

"Go home." Tessa said simply, finally starting to calm down herself. "But why would you let us go? You hate us, don't you?"

"No. Do the plumbers?" He asked the real question on his mind. He knew this was to perfect a chance to be real. He just knew something had to be up.

"…Yes."

"They're innocent, Midoriya." The red head among them said confidently. "They just want to go home. The people you're interning with… they're not good people."

"Midoriya…" Momo muttered quietly, before cautiously making her way over to him while avoiding agitating plum. "Please, listen to Gwen. She only put in a request for anyone of us because she wanted to warn you about this I think."

The greenette looked up, balling his fists. "Alright. Who are they? Tell me that, and I'll make my choice."

"Corrupt. That's what they are. They started off with the best intentions in this world, but… its not the best time to discuss specifics but some really, truly horrendous people infiltrated them when they were just beginning to get their foothold. People who hate alien life. Helping them is not the right thing to do… please, I know you don't know me but trust your friend. I can see it in your eyes, you know something is wrong."

"…Dammit." The greenette sighed, looking up at the aliens. "We've got maybe five more minutes before they Plumbers get here. Run, and don't look back."

Tessa let out a sigh of relief while Plum looked surprised.

"Thank you." The Conductoid said, beginning to walk away. "Plum, come on!"

"Uh, right!" He called, before turning back. "Well… sorry, I guess."

"Me too. Now go!" Midoriya said, gesturing for him to move which he did. Slender arms wrapped around the greenette's neck a moment later.

"Thank you for listening to me." Momo said quietly, and he just leaned into the touch.

"Not to butt in, but we should probably go as well before the plumbers get here." Gwen pointed out, and the two nodded. The creation teen frowned when she took in her smaller friends face however.

"What? Is something wrong?"

"You… you look like Iida did." She said, and all to suddenly he stopped, as his eyes widened. "Izuku?"

"I…. I'm angry. With the plumbers and myself for not seeing it."

"That's not-"

"No, hang on. But if I looked like Iida…. MOMO, WE'RE IDIOTS!" He suddenly yelled, with panicked eyes and she just looked at him confused. "We all are in Hosu. Why the two of us picked here is obvious but we never asked Iida why he came here! This is where stain attacked his brother, and it's where he could strike again… and the most opportune time…."

"Would be right now." The raven haired teen finished, her own eyes filling with fear. "You don't think…."

"I do. That idiot came here to fight stain." He nodded, turning and slamming in his watch, turning into Blink once more. "Let's go, we got to find him and now!"

"Not without me you two aren't!" Gwen called, her body shifting back into her purple form. "Midoriya, you're my intern now. And I give you both full permission to fight."

With that, the three took off.
