Dizzy, that's how Tony Stark felt after waking up somewhere unknown in his armor after doing something, oh yeah, he made the snap to end Thanos' forces and the Mad Titan's life.
"Ouch." he heard a child's voice, familiar one until he realized that was Morgan. Looking at his left he saw the girl sitting on the ground confused, behind her Steve Rogers looked around, watching for danger, he wore his costume and had his shield with him.
"Where are we?" asked Natasha Romanov from Stark's right, she was in her black costume, Stark quickly looked at himself to found out he is wearing his armor and his helmet was folded into it. However, there was something irritated the genius father: he absolutely had no idea where they are.
"I guess we're in a small tunnel." exclaimed Rogers, further inspecting him Tony realized that his friend isn't wearing his helmet.
"But where?" asked Morgan from his father, the four years old was lost despite three person she knew were around here.
"Considering the climate and the cherry trees nearby, we're in Japan." replied Tony this time surely.
"Okay." accepted the girl easily.
"Japan? I hope we aren't in a period which could cause trouble." quipped Steve.
"I agree. I don't like the idea of fighting with Imperial Japanese soldiers." added Natasha.
"Atleast we could meet with another Captain America." joked the older Stark.
"Are you alright?" suddenly a teen's voice asked them, looking there they saw a boy in black gakuran uniform. A boy with green hair and eyes. And the hair was a short mess of fluffy, dark green hair.
"Hello kid. Contacts, dye or just anime?" joked the father.
"Err. My hair and eye colors are natural." replied the teenager back in English.
"Pardon?" now Cap was surprised.
Suddenly the sewer's manhole was thrown out with great force and the adult men reacted in reflex, in the end the super soldier caught and took the boy into a forcefield-like energy shield made by the armored man, at the time Romanov stood in front of the girl and a green, sludge-like thing which lived bounced of the shield.
"What the hell?" swore the Japanese Sludge Villain and the American genius before someone leaped out the sewer and threw a mighty punch to disperse the attacker. In an instant this person also packed up the aggressor's "body" into two large soda bottles. When they stopped the five saw a tall, very muscular, blond man with bunny-like hair bangs, the blue eyed man wore a white t-shirt and green jeans alongside black shoes.
"All Might?" the boy almost screamed from the realization when he saw the Hero in civil clothes.
"ARE YOU ALRIGHT CITIZENS? IT'S FINE NOW. WHY? BECAUSE I AM HERE!" introduced his presence the towering man, All Might was surprised to see the five citizens, one of them using an energy shield to protect the others. "CALM DOWN MISTER. I CAUGHT THE VILLAIN!" exclaimed the boisterous Hero as he showed up the soda cans prisoned criminal.
"They're from the US, All Might-san and they're my far relatives whom with I just met." said suddenly the fanboy and the Pro quickly signed the teen's notebook and made four autograph notes to the others.
"IN THAT CASE HAVE A GOOD TIME IN JAPAN AND STAY SAFE CITIZENS!" said All Might with his booming voice before he sprinted away with the captured baddy.
"Did you just lie to that Vigilante?" asked Stark curiously from the greenette after the latter had his talk with the lighting bruiser.
"Uhm, yes?" replied the boy before he realized the fact, he just lied to the Number One Hero of Japan. "OMG! I just lied to All Might!" gasped the Junior High Schooler.
"Calm down kid. I don't think that could be that bad." tried Rogers to calm the student down.
"Who is All Might?" asked suddenly Morgan from the boy too, this snapped back the latter into reality.
"He is the Number One Hero in Japan. Heroes are enforcing the law by using their Quirks AKA superpowers to protect and save lives of the civilians. He didn't wear any of his hero costumes right now." answered the teen.
"So, he is popular." noted Romanov.
"You didn't reply to my question." said Tony.
"You four much likely just appeared here. Three of you probably are Heroes but none whom I know, and I have a lexical knowledge about them. The girl is your daughter, you're using an advanced suit to use your energy powers much safer unless you might be a very smart Quirkless person, your friend in the patriotic costume is much likely lot stronger than the average adult male and the woman is possibly stronger than the average adult female. They're also soldiers and spy respectively and you're a person who become Hero after an incident involving weapons which can explain your armor's possible weaponry. And I lied even if I hate myself for it to All Might to save you from getting into trouble." replied the teen.
"You just told him we're your relatives." argued Stark.
"Also you're unfamiliar with the things done here in our world and as a boy who lives here, I can help you." retorted the greenette and the adults were horrified on the fact he just figured them fairly well and their situation.
