@takashichea: Well, it's definitely unusual. When reading it, you sorta get the same feeling as the early parts of rurouni kenshin, where you knew kenshin would curbstomp the baddies. The series has some great fights, but they are mostly from characters who aren't Saitama (his apprentice, the other heros) The artwork is amazing, really top tier. But yeah, it's kind of funny seeing a character with superman level powers, trying to deal with characters who belong in a shonen level series. I would definitely give it a read if you have some extra time.
@phantomrant: I didn't know there was a web comic Is it different from the manga?
Not exactly different. The webcomic is the original canon, where as the manga just adapts it. There're not a lot of differences aside from filler/extra chapters.
The scanlations for the webcomic starts at exactly the most recent chapter for the manga.
It a really interesting read, it about hero (who just being a hero for fun) Saitama fighting powerful monsters and saving people lives. But he beat everyone in one punch (it sound boring, but it is not)
The other super heroes and villains are unique and the art and story is amazing (I only read the Shonen Jump one). The manga is in the US Shonen Jump online magazine now, you can read the first chapter in the free preview
I really do hope the Manga come out over here
Also their are a lot of these scenes
I love one punch man; i have been reading it for a few weeks now. AS uninterested as i was at first, it hooked me pretty easily. In a way it is so silly that it's good. And the art is sometimes really amazing, specifically this one chapter (15) when saitama and his side kick are training in the desert. It's like i was reading anime only it wasn't moving.
