Usopp Friendly Fire Luffy Color-Trap Punchline

Status: confirmed · Technique: chekhov-explicit + dialogue-from-dead-character

The seed / payoff

First on-page named-attack friendly-fire of one Strawhat by another in the series.
Installs the Color-Trap-as-line-of-fire-absorber tactical doctrine — Goldenweek’s paint-trance can be weaponized to make the hypnotized target absorb damage intended for the painted enemy.
Pre-loads later Usopp-friendly-fire-as-comedy and Usopp-takes-the-hit-for-the-team grammar contrasts. Usopp’s named-attack causing friendly-damage is a recurring comedic-register beat going forward.
The chapter closes on the friendly-fire visual punchline — the Color-Trap structurally weaponizes Luffy as a damage-absorber for the Strawhats’ own attacks.
