Notable Attacks/Techniques:

- Fencing Style: Brook's unnamed form of swordsmanship resembles classical fencing. Though it utilizes cutting techniques as well, it specializes in fast thrusts. This sword discipline is also used by Ryuma (due to Brook's shadow that was in him), who are able to use the techniques at a level far superior to Brook's (at least pre timeskip).

  • Hanauta Sancho: Yahazu Giri (Three-Verse Humming: Arrow-Notch Slash): A high-speed technique where Ryuma swiftly cuts his opponent(s) as he approaches them and then re-sheats his blade.

 

    • Requiem la Banderole: Performed much the same as Yahazu Giri, except Ryuma executes a lateral slash against the opponent's chest.

 

  • Aubade Coup Droit (Dawn Serenade: Right-Handed Strike): A ranged thrusting technique that creates a highly compressed blast of air.

 

  • Prelude: Au Fer (Prelude: After): A technique intended to disarm the opponent by destroying whatever weapon they might be wielding at close range.

 

  • Gavotte Bond en Avant (Gavotte: Leap Forward): A thrusting technique in which the user propels himself forward in order to strike an opponent.

 

    • Swallow Bond en Avant (Swallow Leap Forward): An aerial version of Gavotte Bond en Avant.

 

  • Polka Remise (Polka Continuation): A combination technique in which the user delivers several consecutive thrusts against the opponent.


Notable OBD Victories:

Black☆Star (Soul Eater) - Black☆Star Profile (this was Edo Ryuma)

Notable OBD Losses:

Other: Little is known about the real Ryuma, as he has so far only appeared in Oda's one-shot, Monsters (which is canon to One Piece), and as he lived in a timeline well before the current story, his fighting strength is tricky to determine even though he was the strongest man in his time.

Key: Real Ryuma | Zombie Ryuma (possessed by Brook's shadow)
