Usopp Boom Star Named Attack Debut

Status: confirmed · Technique: chekhov-explicit

The seed / payoff

Why this matters

• The Boom-Star is the chapter’s opening-strike rescue-projectile — Vivi’s freedom enables the on-frame strategist role across the chapter.
• Distinct from Fire Star — Boom-Star is gunpowder-cluster explosion (area effect); Fire Star is single-target incendiary. The Bomu Bomu no Mi-ingestion-immunity (Ch. 0123) makes Mr. 5 immune to Usopp’s gunpowder-tier projectiles, but the Boom-Star is effective against non-DF-user targets (wax-constructs included).
• Pre-loads Usopp’s full named-projectile roster.
