First on-page demonstration of First Division Commander Marco’s power.

Why this matters
Oda repeatedly debuts a power by effect first, name later: the silhouette / unnamed demonstration builds
mystique and lets the eventual naming land as a payoff. Marco’s blue flame is shown deflecting an Admiral —
establishing him as a top-tier officer — before the reader is told what the fruit is. Pair-reads with
Jozu’s diamond body, demonstrated unnamed in the same chapter
(Jozus Diamond Body Demonstrated Unnamed).
