One day Koro-sensei was out on the park enjoying the sunshine when all of a sudden, a figuire dressed like a superhero walked up to him

"Can I help you?" Koro-sensei asked

"I'm looking for a big yellow octopus" the guy said making Koro-sensei nervous, the onl;y reason he was save for now was because of his disguise. "Have you seen one?" the man asked

"No I haven't my good sir" Koro-sensei said

"Okay" the man said leaving

"Kinda dopey looking fella aren't here" Koro-sensei said as he sneezed making his fake nose fly off and hit the man. "OH CRAP!" he shouted

"Hey, you dropped your...nose" the man said

"Nice to meet you I am the yellow octopus and you can call me Koro-sensei" Koro-sensei said returning to normal

"You can call me Saitama; And I'll tell you now I can kill most things with a single punch" Saitama said

"I would like to see you hit me" Koro-sensei said

"Very well" Saitama said throwing on of hsi one hit KO punches, only to hit the air.

"Miss me" Koro-sensei taunted, so Saitama tried again "Missed again" a third time "Not even close" a fourth punch "Are you even trying?" Koro-sensei asked

"How do I not hit you?" Saitama asked

"Because I can go Mach 20 baldie!" Koro-sensei said "And from what I've seen of you, you can only go mach 1!"

"What did you call me?" Saitama asked

"What didn't you hear me the first time Baldy, hey Baldy, baldy, baldy, bbbaaalllldddyyy~" Koro-sensei taunted him

"THAT'S IT!" Saitama shouted punching Koro-sensei making his entire right side splatter. "That was rude" he said walking off. Suddenly he felt something on his head. He looked around to see nothing there, he turned back, only to feel the thing on his head again

"Now you're not just baldy, you're Chrome-Dome" Koro-sensei laughed

"What, but how are your arms back?" Saitama asked shocked

"Free swing at this arm and I'll show you" Koro-sensei said as Saitama punched the arm off Koro-sensei before peering down his sleeve

"Nothing's there"

"BOING!" Koro-sensei shouted as he sucker punched Saitama

"What?" Saitama asked

"I regenerate" Koro-sensei said in a sing-song voice

"That's a cheap trick, let's go" Saitama said

Saitama ran forward, only to miss Koro-sensei, the hero looked around, once he spotted the octopus he was slapped around a fair bit

"Come on, hit me, hit me, hit me" Koro-sensei taunted as Saitama missed every punch, and those he did land just made Koro-sensei slow down a bit while he healed.

"Stay still!" Saitama shouted as he leapt into the air and threw a downward punch at Koro-sensei. When the dust from his punch settled he saw nothing but a crater "Regenerate from that" he said

"Don't have to" Koro-sensei said making the hero look around "UP HERE!"

"Oh come on" Saitama said as he saw Koro-sensei floating above the ground

"Having fun yet?" Koro-sensei asked

"I don't have time for this" Saitama said as he jumped into the air, only for Koro-sensei to lift himself up an inch.

"Miss me" the octopus chuckled, "That's not" Koro-sensei said seeing a massive piece of rock came flying at him. He quickly dodged it, only for his robe to get snagged on it making him pummel to the ground

"Now hold still!" Saitama said as he threw a punch.

"Don't think so" Koro-sensei said creating speed clones, He was too fast. Saitama quickly tired out.

"I give up" Saitama panted

"Well, I don't; not just yet" the teacher said as he picked up Saitama and went full speed, "Enjoying the fly, well guess what" he chuckled

"What?" Saitama asked

"A student showed me a little anime call Pokémon the other day and I picked up a little something" Koro-sensei started say

"Huh, what did you pick up" Saitam nervously asked

"Oh nothing much just a little trick called: SEISMIC TOSS!" Koro-sensei said starting to fly in circles before divebombing for the ground "AND YOUR STOP IS COMING UP!"

"WAIT!" Saitma said as he saw the ground was coming up

"Nope" Koro-sensei said as he let go and stopped sending Saitama into the ground.

"RIGHT!" Saitam said getting back up; and dusting himself off, he shifted his feet and then glared at Koro-sensei before running at him with all his might. "HERO'S HAMMERFIST!" he shouted punching a hole in Koro-sensei

"NOOOO!" the yellow creature shouted becoming like Edvard Munch's famous painting 'The Scream'

"Well seems like I'm done here" Saitama said

"Not quite" Koro-sensei said as he regenerated the massive hole that Saitama punched in him

"That is no fair" Saitama growled

"Suck it baldy" Koro-sensei said

Over the next hour the two clashed, one using his strength. The other using his speed. Neither one gaining or losing an advantaged. Koro-sensei's laugh filled the air as he dodged each one of Saitama's punches.

"Stay still" Saitama said

"Nope" Koro-sensei laughed, "Besides I think there is still a piece of rock you haven't clobbered yet" he said

"You bastard" Saitama growled running after the octopus around the area they were.

"You can't catch me, heck not even teh best assassins can" Koro-sensei said

"I will beat you" Saitama said as he was about to charge his punch when a beeping was heard. Making both combatants. Saitama checked hsi watch before paling

"THE SALE!" Saitama shouted

"Sale?" Koro-sensei said

"The market sale which has 30% off everything" Saitama said

"WHAT!" Koro-sensei said

"And I have to go!" Saitama said panicked

"HOLD ON!" Koro-sensei said picking up Saitama

"What?" Saitama asked shocked.

Once they landed Saitama looked to see they were outside the very market he was wanting

"I Shop here too" Koro-sensei said switching to his disguised mode.

"Oh, okay" the hero said entering the shop with the teacher. Each one went different ways one to get things for dinner the other on to get a ton of snacks for in between class. Soon the pair were outside the market once again.

"I think I got everything" Saitama said looking through his shopping. "Yep; got everything" he said before looking at the teacher and held out his hand. "That was a good match" he said

"I agree, that was a good match, a proper test of skill I would say" Koro sensei said shaking hands with the hero

"Look me up for a rematch" Saitama said walking off.

"Maybe, but I may not have long left" Koro-sensei said looking at the date, Nov. 12th "four months left" he said taking off for the school.
