Background / History

Colin was born in Scarborough, a town in the latter half of the Grand Line. When he was two, pirates attacked the town; he survived by hiding in a basement, only to find his parents dead when the Marines rescued him. The World Government subsequently sent him to Tower Forest Island. 20

Driven by hatred for the pirates responsible, Colin trained obsessively, joined P9 at age eleven, and began undertaking missions. He eventually learned that Scarborough had been attacked by the BIG· Pirates because the town had failed to provide sufficiently good food. As Charlotte Linlin and her crew grew ever stronger, Colin concluded that personal revenge was beyond his reach. 20

He withdrew from frontline work and became an instructor at Tower Forest Island. For years, he hoped to find a student worthy of being taught everything he knew; Reg's extreme diligence reminded Colin of his younger self and led him to take a special interest in him. 11 20

After Reg survived the Ninth Tower trial, Colin fulfilled his promise to personally guide him. He resigned his instructor position to focus on Reg's development and created the elective course known as Hell Training. 10 11 13

Reg's faked death and subsequent disappearance left Colin devastated, but their reunion on Long Ring Long Land allowed him to learn the truth of Reg's adventures. By then, Colin had awakened Armament Haki and eaten the Sand-Sand Fruit; he chose to leave his remaining Tower Forest Island duties behind and assist Reg directly. 35 133

As the Kingdom of Zh grew, Colin became its Prime Minister and took responsibility for its administration, diplomacy, intelligence network, military preparations, and covert dealings. Though the office limited his personal training time, he accepted the burden because it gave him the means to prepare for a future war against the Big Mom Pirates. 225 269 277

Colin eventually confronted Charlotte Linlin during the war against the Big Mom Pirates. After pursuing vengeance for most of his life, he killed her in the Calm Belt and buried her body in a sand coffin. The fulfillment of his revenge left him with emptiness and regret rather than the warmth and closure he had imagined. 626 627 656

Appearance

Colin is a thin-faced man who typically wears a black suit and coat. 2 4

• Dresses formally even while working around Tower Forest Island. 2 21
• Adjusts his tie and carries himself with deliberate composure after combat. 21
• Later wears glasses while handling his duties as the Kingdom of Zh's Prime Minister. 269
• Removes his glasses and stores them carefully before serious combat. 577

Personality

Colin is demanding, perceptive, and deeply invested in the growth of those he considers worthy. He recognizes Reg's effort and potential early, offers him information and opportunities unavailable to ordinary trainees, and later treats him as a son. 3 4 23

His teaching is severe rather than gentle. Colin believes growth requires confronting pain, exhaustion, combat, and survival directly; his Hell Training repeatedly forces Reg, Jabra, and Kumadori to attack him under threat of escalating punishment. 13 14

Despite his history as a killer and his association with P9's “Dark Justice,” Colin does not want Reg to become an empty instrument of the organization. He specifically warns Reg not to lose himself during missions. 16 20 23

Colin does not uphold indiscriminate violence against civilians. Having personally experienced the helplessness of a town slaughtered by pirates, he refuses civilian-elimination work unless it is a direct order and regards the suffering of ordinary people with particular seriousness. 150

As Prime Minister, Colin is pragmatic, disciplined, and uncompromising in negotiations. He is willing to make covert deals and use ruthless methods against enemies, but he rejects human trafficking and seeks to minimize unnecessary harm to civilians. 269 270 299

Reg's presumed death affects Colin profoundly. He drinks heavily in Water Seven and violently drives away others, yet continues to believe that Reg may have survived because of his promise to do so. 35

Although his hatred of Big Mom repeatedly threatens to consume him, Colin gradually learns restraint. He refrains from acting before the right opportunity, treats Katakuri with measured respect as a prisoner, and waits until he and Reg can face Charlotte Linlin together. 267 299 606

Abilities & Skills

Six Powers

Colin has mastered the Six Powers and uses them fluidly in combat, including against groups of dangerous beasts. 2 21

• Shave — Moves with explosive speed, fast enough that Reg initially struggles to follow him visually. 21
• Moon Walk — Moves and remains airborne by kicking through the air. 21
• Paper Art — Evades attacks by relaxing and reshaping his body in response to airflow and an opponent's movements. 14 21

• Finger Pistol — Uses it alongside Tempest Kick during combat demonstrations. 21

Haki

Colin has awakened both Armament and Observation Haki. 133 253

• Armament Haki — Had awakened it by the time of his reunion with Reg and uses it to reinforce his body and sand-based attacks. 133 577
• Observation Haki — Awakened after the extreme focus required to target Golden Lion with Sand Prison; he initially struggled with the resulting sensory noise. 253
• Paper Art-derived perception — Before awakening true Observation Haki, Colin could draw out basic predictive applications through his bodily control and Paper Art. 21

After eating the Sand-Sand Fruit, Colin gained the ability to create, control, and transform into sand. 133

Combat Experience

Colin can overwhelm trainees even while suppressing his physical strength to roughly their level. He anticipates Reg's attacks through instinct, experience, and bodily control rather than relying on Haki. 14

• Fought continuously against Reg throughout years of sparring and physical conditioning. 14 19
• Defeated and intimidated numerous primeval-forest beasts. 21
• Displayed enough killing intent in Water Seven to clear a bar and subdue a disruptive patron. 35

• Battled Golden Lion alongside Issho, using his sand abilities and Haki to withstand the pirate captain's pressure. 245

Instruction and Training Design

Colin is an expert teacher of physical conditioning, combat fundamentals, meditation-based body control, and the Six Powers. 11 12 21

• Explains the division between leg-based Six Powers—Shave, Tempest Kick, and Moon Walk—and meditation-related techniques—Finger Pistol, Iron Body, and Paper Art. 12
• Designed Hell Training around repeated combat, wilderness survival, scouting, hunting, and coordinated attacks. 13
• Arranged for Kumadori to teach Reg meditation and Life Return-related methods when Mountain Hag declined. 13

• Commands and deploys Black Ops personnel for intelligence gathering, surveillance, infiltration, and battlefield reporting. 299 357 606
• Negotiates from a position of strength, including setting strict limits and payment terms for the Kingdom's covert Waver-warship trade with New World pirates. 269 270
• Maintains informants within hostile territory, including Fitch within the Big Mom Pirates' sphere of influence. 267
• Conducts covert reconnaissance personally when necessary, including infiltrating Germa facilities and Punk Hazard. 573 574
• Can extract intelligence through intimidation and torture, as demonstrated during his interrogation of Vander Decken IX. 299

Relationships

• Reg — Student and surrogate son figure. Colin mentors Reg personally, shares his past with him, and supports his decision to take the P9 member assessment despite fearing for his safety.

• Kumadori — Cooperates with Colin in Reg's special training by teaching meditation methods. 13 15
• Joey — Fellow P9 instructor and contemporary; Colin warns Reg that Joey holds grudges and asks him to submit Reg's assessment request. Despite their differing paths, Colin and Joey remain longtime friends and rivals, eventually fighting their fifty-first match to a draw. 15 23 453 455
• Mountain Hag — Colin sought her assistance with Reg's training; she declined to teach Reg directly, but Kumadori agreed to help. 13

• Berg — The Kingdom of Zh's Minister of Finance and one of Colin's principal administrative subordinates. Berg regularly brings Colin major financial, diplomatic, and domestic matters requiring his judgment. 269 277
• Doflamingo — A wary business partner and adversary in negotiation. Colin uses knowledge of Doflamingo's Celestial Dragon heritage to maintain the upper hand while arranging covert warship sales through him. 269 270
• Fitch — A covert informant within the Big Mom Pirates' territory who relays Perospero's intelligence to Colin through Transponder Snails. 267
• Ember/King — A powerful enemy whom Colin fought while infiltrating matters connected to Germa and Kaido. Their battle ended inconclusively when Reg rescued Colin before Kaido arrived. 577
