About this show

Saitama is a hero who only became a hero for fun. After three years of “special” training, though, he’s become so strong that he’s practically invincible. In fact, he’s too strong—even his mightiest opponents are taken out with a single punch, and it turns out that being devastatingly powerful is actually kind of a bore. With his passion for being a hero lost along with his hair, yet still faced with new enemies every day, how much longer can he keep it going?

I prefer dubs, as I'm not a weeb, so that didn't throw me off. This often hilarious anime that pokes fun at comic book and anime tropes was the gateway drug for me into this world. You can't help but cheer for the clueless hero, Saitama, and his "sidekick" Genos the cyborg. Loving Season 2 so far, but I fear it's gonna be too short and I'll have to wait years for a season 3. Such is life. :)

this show is an epic combination of action, comedy, and wonderful artwork. Truly this is my favorite anime. all the anime nowadays copy the same thing: strong protagonistbeats foes, looses friends or family in battles, uses mayic thing to get them back. But One Punch Man is different... He's too strong... That's why I love it.

The fact that he can take some one down with one punch is thrilling alot of people says why dont genos get to do dis and fight like siatamia well actually genos is thats why he ask sitamia to be his master bc he can teach him to train and fight even harder so when that chances come he can fight them easily
