A slightly tweaked take on our titular hero

Just when Saitama was doled out enough points to become S Rank he wakes up in another world full of monsters, magic, and kings. How will he adjust in this new world?

Long before the start of what would become the story known as One-Punch Man, someone ended up within the world and has gone on to have his own adventures. Now with the 'story' about to start he attempts to guide the main players from the sidelines until such a time as they might need his assisstance. Unfortunatley as with most plans things don't go accordingly for long.

Saitama had enough of it. He saved Humanity for 3 years, and not even one person knows who he is. Everything he did for them. Hell, humanity would have gone extinct without him. After all, it's not like he cares if they did go extinct. So Saitama thought "Maybe becoming Evil will do it"

After a chance encounter, "Kingu" decides to set out on the path to become "strong". But even if he becomes "The Strongest Man on Earth," he still has a long way to go to overcome aspects of himself, beyond weakness. A path where he'll meet people who also need to defeat their weaker self and find true strength, even if they themselves don't know it. [Warning: Webcomic Spoilers].

What if Saitama was actually praised and acknowledged for his feats instead of always taking the brunt of mob mentality and credit stealing? This is the story if that had been the way his life played out instead. (Note: Currently Being Rewritten/Updated, keep in mind when noticing a difference in chapter quality and inconsistencies with the narrative).

You all know the thoroughly disproven theory that Blast is a future version of Saitama. But what if instead Saitama really was Blast? Basically he's older and does all the stuff we know Blast did, except the Cube and God shit. No idea whats up with that so I'm not touching it.

After a terrible subway accident that killed a young girl, Fubuki gets depressed and gradually realizes that the heroic path may not be for her. Indeed, her horrific meaning of life is to become an empress who will subdue all humanity."But how?" You might ask. You will discover it by reading this story to the end. NOTE: This story includes the manga and webcomic.

She didn't need saving — but the baldy saved her anyway.

Dr. Genus was the pioneer of cloning technology, and a strong believer in redundancies. Thus, during the destruction of the House of Evolution, the original Mosquito Girl Matsumi makes her escape.

King should have know better than to touch the weird orb before him. Then again, it's not like he wasn't enjoying the benefits that came after.
