Dragon Named At World Council As Revolutionary Threat

Status: confirmed · Technique: chekhov-explicit · prop-tell · parallel-arc-structure · Payoff: Ch. 432

The seed

First on-page sight of Dragon’s face (he was silhouette-only in Ch. 100). The diamond-shaped tattoos canonize as actual facial markings, not silhouette-stylization.
First on-page utterance of revolutionary as a class-label — pre-loads the Revolutionary Army.
The 5-6 year WG threat-projection canonizes Dragon’s trajectory on the WG’s internal timeline. The fact that the WG is already asking member-kingdoms to participate in his capture confirms the Revolutionary Army is cross-kingdom-significant at flashback-time.
Wapol refuses to participate in the Dragon-hunt — the short-sighted-tyrant decision that contributes to Drum’s eventual loss (Wapol cannot face Blackbeard alone). Dramatic-irony stacked.
Pre-loads forward-canon: the Revolutionary Army’s explicit naming, Dragon’s identity as Luffy’s father, the D.-clan thread, and the long-term Dragon-as-King-of-the-Pirates’-father parallel-structure.
