Best CP9 members One Piece

Rob Lucci wins 79% of its duels and tops the One Piece CP9 member ranking ahead of Kaku, holding 1530 ELO points over 87 duels.

The gap at the summit speaks volumes: 135 ELO points separate Rob Lucci from Kaku, a margin that reflects the Cipher Pol assassin's dominance in the Water 7 arc's collective memory. Kalifa secures third place with 1332 ELO, while Jabra and Blueno round out the top five in a tighter cluster. The middle ranks reveal how technical prowess and screen time shape perception: characters who displayed elaborate fighting styles or memorable quirks hold stronger positions than those who served purely functional roles. At the opposite end, Spandam languishes at rank 9 with 934 ELO and a 27% win rate, a predictable outcome for a character whose cowardice and incompetence define him. Between these extremes, Nero occupies rank 8, suggesting that minor antagonists who exit early struggle to leave a lasting impression on the fanbase, regardless of their demonstrated abilities.

This ranking draws from 5958 duels submitted by 339 players across 9 contenders, updated on 10 October 2026. The sample size grants legitimacy to the hierarchy, though the spread in duel counts per contender reveals uneven exposure: Kalifa faced 120 duels while Spandam managed only 82. Rob Lucci's commanding lead likely stems from his role as the arc's primary threat and his continued relevance in later storylines.

How this ranking is computed

Every duel won lifts a contender and every loss drops them, by an amount that depends on the opponent's strength: beating the leader is worth more than beating the last. It is an ELO, the same principle as in chess. Duels are not drawn at random — an adaptive entropy sort puts the least predictable match-ups first, which settles the ranking far faster than a full round robin. A worldwide ranking is only published past 30 completed plays. Known limit: a contender who has faced few opponents keeps an approximate score, and the bottom of the table moves more than the podium.
