Saitama : “If the heroes run and hide, who will stay and fight?”
Saitama : “Human beings are strong because we have the ability to change ourselves.”
Saitama : When I was a little boy I wanted to be a hero. Not some damn business man. But a superhero who could send rotten villains like you flying with one punch.”
Genos : “If this is the path you choose to walk… I will not interfere. But if you turn the people against you… Will you be able to function as a hero? This worries me. But if you ever get in a tight spot… I will be there”
Saitama : “If you really want to become strong, stop caring about what others think about you. Living your life has nothing to do with what others think.”
Dr. Kuseno : “You are calm and intelligent, but youth can invite disaster. Do not fight alone.”
Saitama : “I’ll leave tomorrow’s problems to tomorrow’s me.”
Saitama : “In exchange for gaining strength, have I lost something more important as a human being? Emotions used to swirl within me when I fought. Fear, impatience, anger… But now… Day after day, after one punch I go home unharmed and wash my gloves.”
Garou : “This strength doesn’t make any sense. It’s not fair. It’s like he’s made up of the world’s unfairness. As if he is the personification of justice… of course. Didn’t I already know? This world is unfair. Justice and evil are decided by others. That’s how the world is. To oppose the unfair power known as justice, I have to obtain the unfair power known as evil. To defeat the unfair beings known as heroes I have to become an unfair being myself!”
Saitama : You gotta train like hell until the point where your hair falls out. That’s the only way to become truly strong.”
Saitama : “In exchange for power, maybe I’ve lost something that’s essential for a human being?”
Saitama : “100 push-ups, 100 sit-ups, 100 squats, and a 10km run EVERY SINGLE DAY!!!”
Saitama : “I’ve become too strong.”
Sweet Mask : A hero must be tough, strong and beautiful… As well as able to promptly and splendidly eradicate evil.
Saitama : “I’m just a guy who’s a hero for fun. I never lose. And the surface is guarded by me!”
Mumen Rider: I know no one expects much from me! And I know better than anyone how useless a C Class hero is! I know I’m too weak even for B Class! I know more than anyone else that I’ll never beat you! But I must fight you anyway! I’m the only one left! It’s not about winning or losing! I just have to stand here and face you!
Saitama : “You have to keep doing it. No matter how difficult it gets. It took me a full 3 years to get this strong.”
Garou : The popular will win, the hated will lose, it’s such a tragedy. Then I won’t lose to anyone. I will become the strongest monster ever and change this scenario.
Saitama : “Who decides limits? And based on what? You said you worked hard? Well, maybe you need to work a little harder. Is that really the limit of your strength? Could the you of tomorrow beat you today? Instead of giving in, move forward.”
Hammerhead : “Why do you have to pay money to eat?! Can’t we all just share?! Where is freedom in the world?! All are slaves to labor!! The rich grow fat… While the poor die!!”
Saitama : Heroes and the police don’t do their jobs because someone says “please”. Right?
Saitama : “I’m not a hero because I want your approval. I do it because I want to!”
Bang: You are too young to worry about failure. In a pinch, just muddle through. The outcome won’t change, so that’s best.
Saitama : “Stop right there! If I watch you kill a kid in front of me, I’ll have nightmares.”
Saitama : “There’s no sign that the evils of this world are disappearing. That hasn’t changed since I became a hero. So I guess that means I haven’t really made a difference.”
Genos: “You may be after King but I know someone who’s stronger. More importantly I am stronger than YOU!”
