Author's Note: Yep, doing another crossover, that no one saw coming. I've been watching the MLaaTR series on Hulu and I am loving it. And this 'what if' story just popped into my head. Also there may be a bit of AU because I'm using a prediction that someone on YouTube said, also I don't read the manga, so expect some mistakes maybe. Anyways here it is. PLUS ULTRA!

Everything was going fine, until this villain showed up. It was meant to be a simple trip to the mall to celebrate everyone's first experience with the heroes of today with their provisional licenses. Another thing to celebrate was Eri finally mastering her quirk and fixing Izuku's arms, so now he can use them as much as his legs again. Not only that, Izuku also manage to get a handle on Black Whip as well. But all that was ruined when this one villain appeared.

The strangest thing was that he was a robot? He kept going on about how 'Cluster Prime' will take over this dimension. The heroes in the area would not have that as heroes like Gang Orca and Hawks began fighting the villain as he called other robots that kept on getting easily destroyed by the heroes. Meanwhile class 1-A was helping civilians out of the building. Izuku making sure to do one last check on the place when he found one last civilian very close to the villain robot that started this all, who luckily didn't notice them. Izuku then proceeded to help the civilian away when the main robot pulled out a strange device.

"Darn it! Guess we'll just go back to the original plan of conquering our home dimension's Earth," the robot said pressing a button in the device and a warp gate suddenly popped open. Izuku has so many questions running through his head it took every ounce of concentration to not mumble them all. Suddenly the device began to spark and the gate seemed to waver. "Shoot, the dimension gate is destabilizing! Welp, see ya suckers!"

The robot said jumping into the gate as it began to collapse. Seeing this, Izuku threw the civilian as far as he could, and then came a bang. The last thing Izuku heard was Uraraka's cry.

"DEKU!"

When the green haired boy came to, he was outside, within a small area of the mall that appeared to be ripped out of the building itself and put in the middle of a field. Izuku began to look around, finding his yellow backpack that held his school supplies and hero suit. At the moment he was wearing a casual white shirt that said ウルトラプラス (Plus Ultra) with a green sweatshirt over it, middle being open revealing the wording. He also had on a pair of simple black pants and his signature red shoes.

Izuku then decided to look for some civilization, traversing through the forest surrounding the field. After walking around for a few hours, Izuku finally found the beginning of civilization, and an idea of where he was. Up on a mountain in the distance was the name of a town. "Tremorton? Well I guess that's the name of a town of sorts?"

Izuku saw the town at the bottom of the mountain and ran to it, using a bit of One for All to speed up the arrival time. Once he got to the edge of the town, he powered down his quirk. Doing a quick look around, he discovered the town's common language was English. He had to thank all those years of taking English Class for how he understood all this so well. He was also very fluent at speaking it too.

As he kept walking around he noticed how 'normal' these people were. It's like they had no quirks whatsoever. Turns out they didn't, no one did. Not even the weatherman from New York on a TV he found in a store window showed signs of a quirk.

"Strange, what happened to me?" He then remembered something that robot villain said about home dimension. "Wait did I really dimension jump?" He then proceeded to mumble while walking on about how incredible and impossible it was for this to be true.

He then passed by the town's local high school just as it's principal stepped outside to enjoy a cup of joe. He was short yet plump and wore box-like glasses. When the man saw the fourteen year old mumbling up a storm walk by he did a spit take with his coffee. Finding a student out of school at his age seemed strange, and he felt the need to correct it.

"Excuse me young man!" At the principal's words Izuku had snapped out of his mumbling state and looked at the short man before him. "You are aware that skipping school is a high offense, correct?!"

Izuku did a quick translation of what the man just said in his head. Realizing that this man probably thought he was just a teen stirring up trouble and not going to school. "Oh! I'm not trying to skip school. I'm a transfer student from Japan." He answered in the best English he could speak.

"Oh, a transfer student huh? What grade are you in?"

"Freshman."

"Welp, welcome to Tremorton High. You start today Mr…"

"Midoriya, Izuku Midoriya," the green head replies, remembering to put his actual name first.

"Izuku Midoriya. Come along now, let's get you into class."

Izuku's first class was math. The principal had led him into the room as everyone looked at him. "Alright Mr. Midoriya, introduce yourself."

Taking a deep breath, he did as the principal asked. "Hello, I'm Izuku Midoriya. I'm a transfer student from Japan. I hope we can all be good friends."

He then took his seat. It was next to a currently empty seat, that is until in the middle of a pop quiz they were given, (Izuku chose to take it, even after being given a choice) something entered the classroom.

"Sorry I'm late! There was this strange anomaly going on in the woods, but it doesn't look like much trouble," said a joyful robotic voice. This caused Izuku to look up and see a white and blue robot girl with robotic pigtails on her head. She then proceeded to sit in the empty seat having the test in her grasp.

After quickly finishing the test, Izuku turned it in around the same time a kid wearing a sweatshirt like his only crimson red, and had black hair. As said kid was walking back to his seat, Izuku behind him, a piece of paper was thrown at him. Izuku quickly caught the paper in midair. A couple groans of disappointment were heard as the boy looked behind him to see the green bean holding the paper in his grasp. Izuku then headed back to his desk as the other kid did the same. Izuku then opened the paper to see if anything was written, and there was. 'Nerd' was all that was written on it.

"Hey," came the robot girl's voice from beside him. He then gave her his attention. "That was cool of you to catch that paper in midair."

"Oh, it was nothing."

"Y'know, I've never seen you around here before. Are you new?"

"Transfer student," he answered simply.

"Cool. Where are you from?"

"Japan."

"Cool, I've been there a few times. Once I lost my language disk so I was stuck speaking in Japanese for the entire day. You have no idea how hard it was for people to understand me."

"Okay?"

"S-Sorry, I didn't mean to say some boring story."

"It's okay, really."

"You're really good at speaking English, no offense of course."

"It's fine, I just really paid attention in English class."

"Cool."

"Ms. Wakeman, Mr. Midoriya," the teacher says. "Do you mind continuing this conversation later? There is still a quiz going on."

"S-Sorry!" both replied at the same time.

At lunch, Izuku was looking for a place to sit as he noticed the students of the school was split into the categories of popular and unpopular. He found the robot girl again as she was waving to him. She was sitting with the crimson sweatshirt wearing kid from before and a redhead with a fancy shirt and black vest and beige khakis.

"Hey there!" redhead said. "You're the guy who helped Sheldon earlier. Name's Brad by the way."

"Izuku Midoriya."

"Cool name, and this robot girl you were talking to here is Jenny."

"Hello again," she replies.

"Hello to you too," Izuku responds. He then looks at the last of the three, named Sheldon, and begins to talk to him. "Hey, Sheldon right?" He nods. Izuku then pulls out the crumpled paper from earlier. "This was the paper that was thrown at you. It says 'nerd' on it."

"Sigh…" Sheldon responds. "Figures."

"This wasn't the first time?"

"No. Not to be rude but why do you care?"

"Well, I'm kinda a nerd myself."

"Really?" All three ask.

"Yep."

"Hey what's up with that writing on your shirt?"

"It says 'Plus Ultra'," Jenny translates. "Why does it say that?"

"That's my other school's motto, 'Go beyond! Plus Ultra!'"

"Okay, that… is a cool motto," Brad comments. "One last question though."

"What?"

"What's up with your hair looking green? That's not natural, right?"

Izuku had to think what to say quick. He had noticed that most people didn't have crazy hair pallets, except for Jenny. "It's hair dye. I just liked the look of green hair."

"Well you rock that look!"

"Oh please. That look won't get you anywhere," came a snobby British voice from behind Izuku. They all turned to see two women, one tall and colored, the other short and has a gothic look to her.

"Yeah, you could pick any hair dye color but you chose green? Lame…" said the short one. Her voice being different from the British one.

"Leave him alone you two, he's new here," Jenny defends him.

"Of course he is," said the taller one, her being the owner of the British accent. "No one in this school would simply waltz in with that hair style and expect to be popular."

"I'm not really looking for popularity. Really" Izuku responds. "I like my hair the way it is."

"Hmph! Well, you won't be so confident when you're shown your place on the bottom. Good day." With that said, the two women walked away.

"Who are those two?"

"The crust cousins, Tremorton High's 'petite queens'," Brad informs.

"Me and those two always seem to get into some kind of rivalry every week or so trying to show each other up," Jenny adds.

"Yeah, but they're not the ones to be wary of most," Sheldon adds also.

"Who would that be?" Izuku asks.

"Don Prima. The destroyer of unpopulars," Brad answers.

"Is that his real title?"

"I don't know. The point is, he's one of the most, if not, the most popular kid in school. He throws some of the most epic parties, but even so, he's a major jerk that likes to show off and hates nerds."

"Sounds familiar to me," Izuku thought thinking of a certain explosive teen. The lunch bell then rang as it was now time for the final class of the day, fortunately for all four of the teens, they had the same class; P.E.
