One Punch Man follows a hero that can end all of his fights with one punch, and that makes him so frustrated. Now you might be thinking, what's so interesting about that? Don't you want to see the hero struggling to kill his enemy? Well not this time. Here, you will see a super-overpowered hero struggling to find a stronger enemy, struggling to feel the thrill and adrenaline of the fights he once felt when he was weak. Was his training to become strong not worth it after all?
This anime is so random so the plot is unpredictable, in good ways. The animation and the fight scenes are SUPERB! It has the best fight scenes I have ever seen in all of the animes I have ever watched. Go ahead and watch it! It will be worth your time.
