|Onepunch-Man, not that he is hiding his full strength just that no opponent is strong enuff to make him go all out.
Quote from Description
Follows the life of a average hero who manages to win all of his battles with only one punch! This ends up being the cause of alot frustration as he no longer feels the thrill and adrenaline of fighting a tough battle. Maybe all of his rigorous training to become strong wasnot worth it. After all what's so good about having an overwhelming power?
"The oldest and strongest emotion of mankind is fear, and the oldest and strongest kind of fear is fear of the unknown"
