In City-A, it was the average day. Everyone and everything was quiet and peaceful. However, it was all disturbed by a large explosion. Everything was sent flying and there was immense devastation all caused by a tall purple antenna having creature named Vaccine Man. The mysterious being summoned spheres of energy and launched them to the ground, unleashing even more destruction on the city, as a News report came on a special someone's TV.
News Reporter: "As you can see, explosions are going off behind me. The wake of destruction left by this monster is at an unprecedented scale. The hero association is analyzing the threat level in order to-" is all the man could say before something caused the footage to halt.
??? "Time to go." Said an unknown someone, as we see two figures walk through a doorway.
In a broken and demolished city, we see a small girl crying for her mother and father. The monster reached toward her with his enlarged hand, and attempted to crush her, however she was saved by a man in all black, who was accompanied by a bald man in yellow and red.
Vaccine Man: "And just who are you two?"
Kaetos: "I'm an Undefeated superhero."
Saitama: "And I'm just a guy who's a hero for fun."
Vaccine Man: "You're kidding. What kind of half-assed back stories are those? Mine's far superior, I was formed from the pollution man rod upon the earth. I am Vaccine Man!" Said the purple beast.
Both Kaetos & Saitama stopped paying attention to the momster's rambling, up until he started transforming.
Vaccine Man: "You say you do this for fun?! FOR FUN?! How dare you confront Mother Earth's apostle for such a mindless reason? And how could a lowly lifeform such as you be prideful enough to call yourself undefeated!!?? Yet what could be expected from huma-" Is all the monster could say before being punched and killed by Saitama, and then instantly burned to crisp by Kaetos' Heat Vision.
Saitama stands there with his fist in the air before looking at it in aggravation.
Saitama: "Not again... all it took was one punch." Saitama thought, dropping to his hands and knees. "DAMMIT!" The bald hero yelled in anguish, as the hero in all black covered the little girl's ears.
<<intro>>
Kaetos: "Oy Fey, your gonna pop her eardrums." Kaetos said, removing his hands from her ears and lifting her up.
Saitama calmed down and stood up. "Sigh My bad."
Kaetos: "I'm gonna take her to a hospital, see you later... chrome dome." He said, before going into the sky and flying away.
Saitama: "Well see you la- HEY!" Saitama said, annoyed at that "chrome dome" comment.
Timeskip
Kaetos left the girl at the hospital, feeling they could handle her situation. Kaetos flys through the sky, but is blasted by a wave of flame unsuspectingly, however he is completely unharmed. He looks at his attacker, unamused. "And you are?"

FT: "You're a tough. Call me Fire Tyrant, for the brief amount of time you still have."| Kaetos: "Sigh Let's get this over with."
Kaetos and his flaming foe flew high in the sky, as the monster attacked the hero in black (hey that rhymed!) with all the might he could muster... to no avail. No matter what the beast did, he couldn't harm our hero in the slightest. | "Done wasting time Major ugly? Ready to wrap this up?" Kaetos mocked. Fire Tyrant, frustrated and aware he could not defeat Undefeated, he tried a different approach.
"If I can't roast you..." Fire Tyrant said, looking down at the watching civilians. "THEN I'LL ROAST THEM!" Said the monster as he formed a large ball of flame in his hands. "FLAME SPHERE!" He yelled out before sending the ball towards the ground, causing several citizens to scream and flee. But the hero flew under the attack and punched in its direction, and the resulting shockwave destroyed not only the attack, but even Fire Tyrant himself.
"That was easy." Said our hero before flying to his home in Z-City, not knowing just who had watched the battle take place.
He arrived at his house just across the street from Saitama's. He entered the house, grabbed himself some clothes, and took a shower, thinking about the day he had. "That monster went down pretty easily. I wasn't fighting seriously, not even close, but he died so quickly anyway." Kaetos quickly, washed up, got out, put his clothes and deodorant on, and went outside. He went to his roof and laid down, on his phone. A bee flew around him and landed on his head. He gently picked it off and put it down. He then started honing in on a distant sound. He looked behind himself and saw bee's. Massive, humanoid bee's, dozens of them.
"Now, let'zzzz see if there are any humans to rid thizzzz place of."
"Yezzz, we can't have any humans threatening the hive." Said the bee soldiers.
"I thi-" Is all a bee soldier managed to say before getting punched into paste by a black blur. Said blur then flew around destroying each and every bee in the sky in the blink of an eye. The blur then landed in the street. The blur was obviously Kaetos.
"I hate to say it but... maybe Saitama's right." Kaetos thought while walking into his home. He got in his bed and thought: "All this strength... is getting boring." He then drifted off to sleep.
The next day.
Kaetos is up, drinking a cup of water. He hears Saitama's dealing with the Subterranean's (the real ones) and thinks: "Huh, at least I'm not alone at the top." He then heads over to Saitama's house.
Meanwhile
We see a certain blonde cyborg stand in a field of dead, drained Cow corpses. He then walks forward to the city ahead.
