The character
A cabin boy Luffy frees from Alvida, who then walks into a Marine office and asks to be trained. Pink hair, glasses, and a dream to become a Marine who actually helps people.
Character development
From a terrified cabin boy swabbing Alvida's deck to a Marine cadet who walked into enemy-adjacent territory and asked to be trained. Every step of Koby's arc is the same choice made braver: to stand between people and harm, even shaking. The dream he names out loud — Admiral — stops sounding like a joke the moment he keeps standing back up.
Powers & abilities
- Marine hand-to-hand combat training under Garp himself
- Awakened Observation Haki — senses presence and emotion at range
- Courage under pressure — the rarest power in his arsenal and the one that matters
The actor
Morgan Davies — as Koby · Season 1 & 2.
Morgan Davies is an Australian actor whose breakout came with Netflix's Evil Dead Rise (2023) — a horror performance that landed just as their casting as Koby was carrying them into the biggest franchise on television. Davies is non-binary, and interviews around the show made a point of how much Koby's courage-from-weakness arc meant to them.
Known for
- One Piece (Netflix, 2023–)
- Evil Dead Rise
The casting story
Davies was in the original 2021 main-cast announcement — Koby being the fandom's barometer for whether the live-action respected small arcs. Season 1 delivered the whole Alvida-to-Marine-cadet journey, and Season 2 put Koby where the story always promised: under Garp's training alongside Helmeppo.
Why this casting works
Morgan Davies (Evil Dead Rise) gives Koby the shy steel the manga promised: not a mascot, a recruit who chooses the other side of the law from the friend who saved them.
The fan corner
The Koby arc is the fandom's go-to proof that the live-action "gets it" — faithful without being beat-for-beat. The Koby-and-Helmeppo double act with Aidan Scott is a reliable fan favorite, and clips of Koby's first stand against Alvida are perennially re-shared as the moment the show announced its intentions.
