One Punch Man (OPM) If this is base hulk we're talking about (Not world war, green scar, immortal etc.) then he doesn't stand a chance. Saitama easily tanks planet busting attacks without a single scratch. Base hulk is less than mountain level. It would be over in a single punch.

One Punch Man (OPM) Goku is constantly being pushed to his limit whereas Saitama has never reached his. In one punch he was able to cut through a planet bursting beam and kill the one firing it at him, without taking a single scratch. With his dying breath Boros told Saitama he knew he was holding back and that their fight couldn't even be called a battle because of how one sided it was. The only reason Boros survived the first few punches was because Saitama was throwing his weaker normal punches. Now granted Goku is higher than a planet buster but is constantly fighting at his maximum potential and usually barely scraping by with a victory, sometimes at the cost of his life.

Either Naruto-verse or Star Wars for me
