Chopper Horn Boost Named Transformation-Modifier Debut
Status: partial-payoff · Technique: chekhov-explicit · name-etymology · technique-window-as-self-imposed-limit
The seed
The payoff
(Partial. The Ch. 0149 four more transformations claim is now operationally proven via the first named cash — Horn Boost. Forward-canon: Walk Point / Brain Point / Jumping Point / Arm Point will follow.)
Why this matters
Chopper’s Rumble-Ball-form catalogue is the first early-canon named-form Zoan combat-toolkit in One Piece. The Ch. 0149 four extra forms claim graduates from aspirational to operational with Horn Boost; the named-form register itself becomes a Chopper-specific combat-grammar that recurs across the manga.
