You are in Japan on a moped looking for a Hero Agency to be an intern for a Pro Hero. You then run into a red light and you wait for it to change. Then a girl in a school girl outfit appeared on the sidewalk and turn to you.

???(Himiko Toga): "Hey there."

You then turn to the girl.

(Y/N): "Oh hey there ma'am."

???(Himiko Toga): "You must (Y/N) 10, I'm Himiko Toga, it's nice to meet you."

(Y/N): "Nice to meet you Himiko."

Himiko: "What brings you to Japan?"

(Y/N): "I'm trying out some Hero Agencies, do you know where I can fine one?"

Himiko: "Oh theres one where Pro Hero Mt. Lady is the head of her own Hero Agency, right down the street."

(Y/N): "Oh thanks."

Then the light turn green and you ride your moped down the street.

(Y/N): "What a nice girl, helping out a guy like me out."

Then the girl went to the alleyway and then pull out a knife and thought about you.

Himiko: "He's from another universe, I wonder what his exotic blood taste like."

Later, you arrived at Mt. Office and you look up to see the building itself.

(Y/N): "Well, this is it, already done this before and I'll do it again."

You then head into the building and then ring the bell on the table. Then a woman with a purple and white outfit with purple horns and blonde hair appeared at the window.

???(Mt. Lady): "Yes, can I help you?"

(Y/N): "My name is (Y/N) 10 and are you Mt. Lady?"

Mt. Lady then turn to you and see you and she was fascinated from the sights of you.

Mt. Lady: "Oh yes, come into my office, right this way."

Mt. Lady then open the door to her office as you head into her office and sat into a chair across her seat. She then speak in a flirty tone.

Mt. Lady: "So what brings you here?"

(Y/N): "Well All Might told me about you guys have Hero Agencies, so you're the first one I get to work with, but I did work with other teams like the Avengers, the Fantastic Four, the Guardians of the Galaxy, and the Agents of S.M.A.S.H.."

Mt. Lady: "Really, why would you come here to moi?"

(Y/N): "I thought I would get to know the heroes of your universe."

Mt. Lady: "Then you come to the right place sweet pea."

Then another woman came into the room and her outfit looks like it's for mature people.

???(Midnight): "Hello everyone."

Mt. Lady then got annoyed from who came into the room.

Mt. Lady: "What do you want Midnight?"

Midnight: "A little bird told me that the great (Y/N) 10 himself will be here."

Mt. Lady: "He came to me not to you, you old hag!"

(Y/N): "Hey that's not nice."

Midnight then got angry from the insult.

Midnight: "Well maybe you'd be on the lower ranks if you don't have big meaty hands!"

Mt. Lady: "What did you say!?"

Midnight: "Big meaty hands!"

Mt. Lady: "Well these hands ain't just for manicures!"

Midnight: "Bring it on Mt. Moron, bring it on!"

You then transform into Toepick and then open the cage in from of your face and then grab Mt. Lady and Midnight and make them turn to your face. Then they got frightened from he sights of your face losing their color in the process. You then let them go and revert back to human form.

(Y/N): "You're both Pro Heroes, you two have to stop fighting each other and work together."

Mt. Lady: "Okay, just don't show us that face again!"

You then hear some explosions outside.

(Y/N): "Enemy attack, let's get out there and kick some tail!"

You and the Pro Heroines head outside and see that the whole block is destroyed. The Pro Heroines recognizes the damage as it was the work of All Might.

Mt. Lady: "All Might was here and he tore up the place."

(Y/N): "Something tells me that someone is as powerful as All Might but it's not All Might."

You then transform into Studio.

(Y/N) as Studio: "Let's see who's the culprit, I'll need my detective kit."

You then pull out a shovel out of your pocket.

(Y/N) as Studio: "Nope."

You then toss the shovel away and then pull out a stick of dynamite that is lit.

(Y/N) as Studio: "Nope."

You then toss it to Mt. Lady as she toss it to Midnight, then the girls keep tossing it to each other until Midnight put it into a car's hood as it get blown up. Then you pull out a calculator out of your pocket.

(Y/N): "That's not it."

You then toss the calculator and then pull out a picture of Midnight's old costume. You then blushed and threw it away.

(Y/N) as Studio: "How did that get in there?"

You then pull out the detective kit out of your pocket.

Mt. Lady: "So each form you have has a power of their own, and this one has a Quirk that allows to control reality in a humorous way possible."

Midnight: "(Y/N), if you wanted pictures of me on my bad side you could've said so."

You then pull a magnifying glass and then look for clues all over the ground and then you found a foot print. You then use some equipment to measure it and then use your 5 senses to get an analysis. Then you print the results out of your mouth and then read them.

(Y/N) as Studio: "This looks like just like All Might, but on Opposite Day, then that means the culprit is a bizarro."

Mt. Lady: "A what?"

(Y/N) as Studio: "Bizarros are like us but on Opposite Day, some of our powers can be inverted, for example Bizarro Mt. Lady would shrink instead of grow but still retain the increased strength."

You and the Pro Heroines then follow the trail of destruction to All Might as he just arrived in the area.

Midnight: "All Might, why would you attack the city?"

All Might: "Midnight, I just got here."

???(Mightzarro): "RAAAAAAAAAAHHHHHHHHHH!"

Then a All Might look alike appeared out of nowhere and tackled All Might. All Might then see his Bizarro right in front of him.

???(Mightzarro): "Me am Mightzarro, me do opposite of what All Might does, SMASH TEXAS!"

Mightzarro then kick All Might with extreme force and launch him into a building. Then All Might get back up and turn to you and the Pro Heroines.

All Might: "What is this creature and why do I feel weak?"

(Y/N) as Studio: "That's your Bizarro, he's you on Opposite Da, One For All gives people strength, but a Bizarro version of your Quirk will make Mightzarro take strength from every hit you take from him."

All Might and Mightzarro then clash against each other as Mt. Lady use her quirk to make herself a giant and fight off Mightzarro and All Might got out of the way.

(Y/N) as Studio: "Don't worry guys, I'll find the right alien to help!"

You then transform into a small little green sphere with a small arm that double as hands, small oval eyes, small mouth, greener feet, and the Ultimatrix badge is on your forehead.

(Y/N) as ???(Kirby): "Poyo."

Midnight: "What does that thing do?"

Then you inhale hard enough to make a powerful vortex as Mt. Lady, All Might, and Mightzarro hold on to dear life. Then a pinwheel went into your mouth and you jump into the air and then a tornado hat appeared on your head.

Then you release a tornado that blows Mightzarro into a building as the Pro Heroes were shocked from what they seen. Then you inhale a wheel and then jump into the air transform into a Wheel and charges at Mightzarro.

https://youtu.be/I8xP1-nJbO4

You then made 100 laps around the world with Mightzarro in the path. You then revert to base form and then inhale a rock and then jump into the air and got a new hat and then transform into a stone version of yourself and then jump onto Mightzarro and then jump up and down on him until he was defeated.

https://youtu.be/0l6MbTTP9eA

You then revert to human form and then walk off of Mightzarro.

(Y/N): "I'll the new guy Kirby."

You then help Mightzarro up and as he was still hurt.

(Y/N): "I know a good place to keep him safe, Bizarro World, I'll get the Guardians of the Galaxy on speed dial so they take Mightzarro to Bizarro World."

A few hours later, Mightzarro was out cold thanks to Midnight's knockout gas as he was put into a pod that puts him into suspended animation.

(Y/N): "You guys take him to Bizarro World and be sure he's safe."

Rocket: "How do we know when we see Bizarro World?"

(Y/N): "The planet looks like a cube, you wouldn't miss it."

Then Oacket head into the Milano and then take off and head to Bizarro World. You then turn to the Pro Heroes.

(Y/N): "Not bad for my first day, now let's head back to HQ for victory nachos."

Mt. Lady and Midnight then turn to each other.

Mt. Lady and Midnight turn to each other and talk about you.

Mt. Lady: "He really knows what to do, he's like a Pro Hero already."

Midnight: "We should ask him how long he'll be an intern at your agency."

Mt. Lady then walk up to you.

Mt. Lady: "Hey (Y/N), how long are gonna be my intern?"

(Y/N): "How about a week, just to get to know you guys."

Mt. Lady: "Alright!"
