This is chibi Saitama anime paper craft. Saitama is the main character of One Punch Man .
Why is he called “One Punch Man”? Because he beats everyone with just one punch.
He is the super strongest person on earth. He is a superhero that is lonely because no one can beat him or be on par with him in fighting.
Well that’s what I heard anyway, I didn’t personally watch the anime.
As for Saitama chibi paper craft it is made by Rava Master. Assembling it is easy for beginner.
