Meaning

In "One Punch Man", character KING's heart beats rapidly when extremely scared, making a "thump-thump" engine-like sound (10 times normal speed). In the manga, it's mistaken as him preparing to unleash a special move, but it's actually just his scared heartbeat. Saitama's achievements were mistakenly attributed to KING who happened to pass by, making him known as the strongest man on Earth.
