Chapter one

It was a regular day, people were riding a train in silence listening to the sounds of the train horn blaring. People below can be seen walking to wherever they are heading simply just minding their own business. All in all it's a regular day.

Suddenly a massive explosion destroys multiple buildings and kills hundreds, and from a crater emerges a large purple humanoid with antenna. He jumps into the air and multiple energy orbs form around him and with a yell he sends them towards the building's that were still standing.

Somewhere else people in suits in a dark room panicking with one yelling at the others" What is the disaster level?" Another responds" dragon for sure." Are there any heroes nearby?!" Smile man and Lightning Max" responds a woman.

Then the two heroes that were mentioned lying on the ground passed out and the purple monster walking away from them. The monster then starts walking towards a girl crying out for her parents. The monster begins reaching out for the girl seemingly to put a comforting hand on the girls shoulder. A cruel snicker is heard coming from him as his hand grows in size around the girl but as his hand clasps down a yellow flash passes by. Confused as to why he doesn't feel anything oozing through his fingers he looks over his shoulder to see a man in a yellow costume setting the now unconscious girl on the floor.

"Your a fast one" the monster says " who are you?" He ask's. A smirk forms on the man's mouth " Just a guy who's a hero for fun" he says. "What kind of half assed back story is that" he says with a vein popping up on his forehead " mine is far superior. I was created by Mother Earth from the constant pollution you humans have been creating, eating away from her precious life force she has created me Vaccine Man! Yet you dare confront Mother Earth's apostle for such a ridiculous reason like fun. For fun!" As he said all this he grew more and more becoming more and more monstrous. " Yet what more could be expected from a human!" He yelled as he threw a punch.

All the while the man in the yellow suit merely looked up with a bored expression on his face, as he watched the first coming towards him he sighed and caught it completely stopping all the force and then twisted the arm attached slightly.

" AHHHH!"was all Vaccine Man could let out as he quickly shrunk back down to his original size as his arm was being twisted. " Everything you said may be true, but even then killing people shouldn't be the only way for you to accomplish your goals" Saitama said as he continued his grip on the monster" You seem to be very strong so you should be able to find another way to fix the problems that this world has, no one has to die."

Then he let go and watched as the monster hung his head in defeat, realizing how easily he was defeated. "What should I do then, my purpose was to kill all of you, but I cannot even accomplish that."

"Don't worry I'm sure if you instead focus on helping others you'll find a way to fix the problems in this world" Saitama reassured with a knowing look on his face" I know because I am also strong, and you put that strength to good use everyone will benefit."

This my first time actually trying to write anything so sorry if the chapter is kinda short I'm gonna try again depending on what people say say.

I should mention I have no idea what kind of speech Naruto would make in such a situation so maybe the whole thing might suck but don't worry I'll keep practicing.
