Razor stands tall and muscular, with broad shoulders and spiked dark purple hair. He favors a white T-shirt, red shorts, and green-and-yellow sneakers. His Nen ability summons 14 numbered humanoid "devils," varying in size and design. Thirteen possess white bodies with blue heads, while Devil No. 0 reverses this scheme, its body entirely blue with white limbs. Enduring childhood abuse and cruel nicknames, Razor turned to crime and murder before Ging Freecss captured him. Sparing his life, Ging recruited him to co-develop Greed Island, earnestly using Razor’s name—a gesture that ignited unwavering loyalty. For over 13 years, Razor served as a Game Master, maintaining the island’s spells and acting as the final challenge in the "Plot of Beach" quest. Though typically relaxed, Razor adopts a ruthless, analytical edge in combat, enforcing rules without mercy—exemplified by executing subordinate Bopobo for defiance. He balances intimidation with respect, acknowledging opponents like Gon’s potential and reflecting Ging’s mentorship. During a high-stakes dodgeball match, he merged devils to counter Hisoka’s Bungee Gum and Gon’s aura-enhanced strikes, showcasing strategic adaptability. His preternatural perception gauges adversaries’ strengths, while his immense aura fuels devastating throws and precise devil control. Razor’s tactics prioritize observation: he let opponents attack first, analyzed patterns, reclaimed aura by dispersing devils, and exploited defensive gaps. Despite losing due to Hisoka’s interference, he accepted defeat gracefully, later discussing Ging’s absence with Gon and expressing hope for their reunion. His persona intertwines ruthlessness, fairness, and introspection—a duality shaped by redemption under Ging’s influence.
