"Zeus huh, never head of you," Saitama said, gazing around his surroundings.
"I am a god you bafoon! Now bow!" Zeus demanded.
"Uh, I'm good, I think I'll stand for now." Saitama replied, "Anyone mind telling me why I'm here?"
Zeus sighed, "When you arrived, a large spike of cosmic energy was created around you. I cannot allow such energy to roam free unsupervised."
"So what, your gonna kill me?" Saitama said in a exasperated tone.
"I cannot allow such a potential threat to roam, Mount Olympus must be kept safe. We cannot let people stop believing their gods are untouchable. A threat of this scale left undealt with could be the downfall of us all."
Saitama, who was in the middle dusting himself off, turned his head towards Zeus, "Sorry, I was t listening. But to me it sounds like you want to fight."
With a rose, Zeus leapt out of his seat. Charging towards Saitama. With a sigh, Saitama raised his fist, lazily ramming it into Zeus' chest. Zeus was sent flying through his throne and laid in a pile of concrete. One of the other gods moved forward, however one god beside him held out his hand.
"Let him have his fun," the god spoke.
Before Saitama could figure out what he meant, a bolt of lightning was sent crashing into his chest. Saitama was flung backwards and rolled back to his feet.
"Insolent mortal, you dare strike Zeus!?"
Saitama felt a grin coming onto his face, if he could take a punch then maybe this would be a real fight.
He got into a fighting stance, awaiting Zeus to make the first move. In a blur of speed, Zeus brought his fist down to where Saitama's head was. Saitama narrowly sidestepped and uppercuts Zeus, making him take a few steps backward.
Suddenly the skies above them roared to life, filled with dark clouds and sparks. Mesmerized by the colors in the sky, Saitama failed to notice a giant beam of lightning barreling towards him until it hit. He flew backwards and through a large wall, landing in what seemed to be a large courtyard. Looking at where he just came out of, Saitama realized that they were in a very large castle. He dodged another one of Zeus' strikes, before getting his in the chest with Zues' large boot.
Saitama leapt forward, reaching eye level with Zeus and unloading several various hooks onto his jaw. Before kicking him in the chest, sending the god barreling backwards.
Seeing that Zeus was still standing, Saitama had an idea. He thought up a new move the other day and was eager to try it out. Saitama figured, what's the point of killing everyone I fight, even if there not a serious threat. That didn't seem very heroic, much less moral. Then again killing monsters wasn't really all that immoral because they weren't human. Prior to what most people would think upon meeting him, Saitama was not dumb. He was actually pretty smart, he just never really showed it.
Zeus was a god, meaning that it's probably screw up some part of the universe if he killed him. So that makes these circumstances perfect for trying out his new move.
Drawing his fist back, Saitama smiled at Zeus, who was getting back to his feet, "You were a good opponent, but the fights come to an end. Serious Series: K.O Punch!"
Saitama punched his fist forward, release a large shockwave. Zeus and the other gods were all sent flying away with immense force, landing with loud thuds. They were unconscious, with somewhat minor injuries. The palace however, was completely demolished.
You see, Saitama's new move worked by redirecting the air pressure from his punch around his opponent, to minimize the impact to them while still dealing a powerful blow.
Saitama looked around at his destroyed surroundings and the lush palace courtyard to the sides of him, "Now how the hell do I get out of here?"
In the end, he opted for just jumping. During his high speed leap, he past several galaxies. He saw a few interesting things. A planet with a face, a purple sun, a race of frog people, a group of space heroes in large beat up ship, and a gigantic man, with horns sticking out of his helmet and glowing white eyes. The beings eyes seemed to follow him in slow motion as Saitama sped through.
In a matter of seconds he was back on earth, somewhere. He looked around his surroundings and saw he was in London. Borrowing, totally not stealing. A map, he found the way back to New York, memorizing the route and placing it back on the vendor stand he took it from. Saitama broke out into a jog and made it back to his temporary room in a matter of moments. He got changed and took a shower, laying on his overly comfortable bed. Only one though filled his mind, he had a new goal now. Not to get home, he could do that later. No, now his goal was to find a worthy opponent someone to give him the fight he'd been longing for. That Zeus fellow was able to put up a decent fight, which showed that there were people in this universe that could take a punch. He would find his opponent, wherever they are no matter what.
Saitama felt his stomach rumble, bringing up a very important question, "What should I eat?"
Sitting in his throne, on his home planet Taa Galactus was deep in though. That man he saw who was moving faster than even his herald, the silver surfer. Had immense power, he could feel it radiating off him. Galactus needed to find him, to have that power for himself. All the things he could do with that kind of power… the possibilities were limitless, Galactus would have that power, no matter what.
