Mr 3 Wax Duplicate Key Forgery Skill Debut

Status: pending · Technique: chekhov-explicit, devil-fruit-application-expansion, prop-tell

Why this matters

First on-page Doru-Doru replica-forgery application — wax-as-locksmith-tool. The fruit can produce functional mechanical replicas (not just sculptural wax-figures or armor). This is a load-bearing fruit-application-tier expansion.

Predicted payoff

• Forward-canon: Galdino (Mr. 3) at Impel Down (Ch. 532+) — uses his wax-key-forgery skill to break Luffy + the Impel Down level-6 detainees out. The Ch. 0176 wax-key beat is the exact pre-installation of that escape-mechanism. Mr. 3 transitions from antagonist (Ch. 0123-0124) → temporary-asset (Ch. 0176) → load-bearing rescue-asset (Ch. 532+) — and the wax-key is the operational thread that crosses all three.
