Izuku stood there having mastered One for All and his plethora of other perfectly balanced quirks. Aizawa of course was not going to let this slide, knowing his strength he made the quirk assessment much more difficult.
"Midoriya, you have to do better than everyone else in the class or I will expel you for your lack of effort."
All was going well until Ochako got to the softball throw.
"Infinity." Aizawa says.
"No problem." Izuku says, still confident he could launch the ball into space.
Aizawa noticed his continued overconfidence and then he noticed someone interesting spying on his class.
"You're not throwing the ball." Aizawa says, smirking evilly, "All Might, I see you hiding around that corner."
'I can solve two problems at the price of one.' Aizawa thinks.
All Might jumps next to Aizawa and poses. "I am here, being taken from my perfectly normal walk!" he says, refusing to admit he was spying.
"Midoriya, to pass you will need to tie Uraraka's score. But you will have to throw All Might instead." Aizawa says, struggling to hold back an evil laugh.
"What!?" the class shouted, even Todoroki who had been silent until now, had his jaw on the ground.
"That's just ridiculous, Mr. Aizawa you can't be serious." Ochako says.
"Midoriya has just been breezing through this test. He needs a real challenge to set him straight."
"I believe in young Midoriya." All Might laughs, "But if I'm going to space I'll need a helmet, young Yaoyorozu, I think your quirk can help me here."
"Yes, sir" Momo says, still half in shock at having All Might arrive. She quickly turns around and creates a stereotypical glass dome space helmet, with a rubber seal.
After a few adjustments All Might seemed satisfied with the helmet and stood next to Izuku.
"We don't have all day." Aizawa says. 'Just fail and stop being my problem.'
After a few words with Izuku, All Might takes a heroic pose with one fist in the air as Izuku grabs his belt and lifts him to shoulder height.
"You know, maybe we should get back and take cover..." Ochako says, fleeing.
The class ran to various different sources of cover, several hiding behind a tower shield created by Momo.
"Now look at how a hero leaves as if he has somewhere to be." All Might yells, "All Might..."
"Smash!" Izuku yells, throwing All Might.
"Into... space..." All Might's voice fades away.
After a pause, as if physics itself was shocked, A massive blast of air broke every window on campus, the class struggling to hold onto their cover. Luckily the rest of the school was at the entrance ceremony and no one could be hurt by all the flying glass.
"Infinity." Aizawa said, after a pause, having left one of the balls in All Might's pocket. 'This problem child... I just want to sleep...'
'Why is he so casual about this' the class thought.
At this point the rest of the staff arrive ready to fight the perceived villain attack, only to stop in their tracks when they notice Aizawa standing normally in front of his students.
"What happened here?" Present Mic asks.
"All Might went to space." Aizawa responds before turning back to his class looking as bored as ever.
"WHAT!" the heroes respond.
'It's going to be a long day' Aizawa thinks.
Meanwhile, at the new international space station.
"Ah, another wonderful day to do some science." a blond astronaut says.
"I could live like this forever." a bald one says in a Russian accent.
"Don't jinx it." the blond replies.
"What could possibly go wrong?" the bald one replies.
"We have an unauthorized opening of the main airlock." A third voice shouts.
The blond gives the bald astronaut a look.
They arrive at the main airlock to see a familiar hero posing heroically.
"I am here, in space" All Might says, maintaining his pose even as his face bounced off the wall.
They all proceed to faint.
"Wait, wait, wait, you're supposed to let me in not pass out." All Might says, panicking and trying to get himself to the inner door. "I'm running out of air here!" he continues as he reaches the door and frantically knocks.
Later, in a room full of computers.
"Houston, we have a problem." the blond astronaut's voice is heard.
"This is Houston, report."
"I am here, looking to get back to Japan!" All Might's voice arrives from the same speaker.
Quite a few of the controllers proceeded to faint.
AN: Yep this is a horrible joke, but this came to my head while I was reading another fic where Izuku is OP yet the author tries to keep the dramatic tension. So I went to the extreme. Don't worry, I'll be back to my usual fic soon (tm)...
