One Punch Man and the Comedy of Invincibility

The joke is structural. Every fight in One Punch Man is a setup whose punchline is that there is no fight. That should destroy the action, and instead it liberates it: with the outcome fixed, the animation is free to be about anything else.

Season one's staff understood this perfectly. The spectacle belongs to everyone except Saitama — Genos burning through his chassis, Mumen Rider refusing to leave, Boros monologuing at the edge of the atmosphere. Saitama's role is to end it, and the ending is always one frame long.

Underneath the gag is a genuinely melancholy premise about the loss of struggle. Saitama got what every shonen protagonist wants and found it hollow. The series is at its best when it lets that sit for a beat before cutting to a sale on ground beef.

It is also, quietly, an argument that power scaling debates miss the point. The strongest character in the room is the least interesting thing about a well-written fight.
