Kuzan

Biodata

Background / History

Kuzan joined the Marines at nineteen and became a Marine Admiral in his thirties, earning recognition as an exceptionally gifted talent. He is a former student of Zephyr and remains familiar enough with him to casually call him “Teacher,” despite frequently irritating him with his laid-back behavior. 12 15

At Marineford, Kuzan intervened when Loa’s uncontrolled freezing aura endangered the harbor, effortlessly freezing the waves before they could harm nearby Marines. Although initially dismissive of Loa, he soon recognized the unusual nature of the boy’s freezing power. 15 20

Sengoku and Zephyr arranged for Kuzan to advise Loa on developing his alleged Devil Fruit. Kuzan turned this assignment into nightly training, tests, and increasingly harsh sparring sessions. 17 20 25 29

After Zephyr decided to leave Headquarters and form the Pirate Guerrillas, Kuzan helped keep the Elite Camp from acting rashly. He subsequently became its instructor while it underwent restructuring. 254 256

Following the Paramount War and Sengoku’s departure from office, Kuzan became Fleet Admiral. The Marines later broke away from the World Government amid a crisis involving Akainu and Sengoku’s death. Kuzan subsequently told visitors from another world that he had set a trap for Akainu and killed him. 665 667 753

Appearance

Kuzan is a tall adult man typically seen in a white suit, with a green sleep mask pushed up over his forehead and a conspicuously wild, mop-like hairstyle. 20

• Often wears or carries a sleep mask, matching his habitually sleepy demeanor. 15 20
• Keeps his Marine coat draped casually over his shoulders. 27
• His body is composed of ice due to the Ice-Ice Fruit. 17
• Has also appeared in a dark blue shirt and white suit vest. 254

Personality

Kuzan presents himself as bored, sleepy, and unwilling to take on unnecessary work. He frequently naps during meetings, speaks casually to superiors, and openly enjoys using his mentorship assignment as an excuse to avoid other missions. 29 30

Behind this indolence, he is observant, mischievous, and dependable. He deliberately provokes situations that will force Loa to improve, such as engineering Arudo’s challenge, yet follows through seriously whenever he agrees to teach or protect someone. 22 24

Kuzan is also pragmatic about strength. He criticizes ineffective movements and techniques without restraint, but recognizes potential quickly and takes visible pride in Loa’s rapid growth. 25 31

His relaxed manner does not mean he neglects Marine duty. Facing Kaido, he rejects retreat when it would leave civilians exposed. During Akainu’s public accusations against him, he insists that Marines require evidence and must answer to the law. He also argues that duty and morality cannot always be reduced to obedience. 391 668 753

Kuzan generally gives people close to him room to make their own choices. He urges Loa to respect Zephyr’s decision to leave Headquarters and, when Loa confides a politically dangerous contingency involving Jones, responds with a warning to be careful rather than condemnation. 254 316

Abilities & Skills

Ice-Ice Fruit

Kuzan is an Ice Man whose body is made of ice. Unlike Loa’s abilities, Kuzan’s ice attacks originate from his own body rather than being created from nothing. 17

• Can freeze large bodies of water and halt dangerous waves with little effort. 15
• Can produce and control ice for attacks, restraints, terrain control, and large-scale freezing. 20 25 27
• Can form temporary footholds by freezing moisture or liquid in the air, but considers sustained long-range aerial movement impractical. 17
• His freezing abilities are highly refined, though Loa’s Dragon Slayer ice is stated to possess a superior elemental quality that can affect Kuzan’s true body. Loa’s later attacks against Kizaru show that this effect is not limited to countering Kuzan’s ice. 31 174
• Can freeze a strait nearly ten thousand meters wide rapidly enough to immobilize an attacking pirate fleet. 660
• Has awakened his Devil Fruit and developed its awakened powers to an exceptional degree. 170

Ice Techniques

• Ice Time — Freezes targets into ice statues; Kuzan repeatedly uses it on Loa in response to being called “Teacher.” 20 21
• Ice Block: Pheasant Beak — A powerful ice attack used to counter Loa’s Ice Dragon’s Wing Attack, destroying frozen stone beneath the collision. He later uses it against Kaido, briefly obstructing a punch at close range. 25 391
• Ice Ball — Fires multiple fast icicles at an opponent. 27
• Ice Age — Freezes an enormous area; Kuzan uses it to freeze Loa and the entire plaza overnight. He later raises a massive ice barrier to contain the shockwaves from Loa and Kizaru’s fight. 27 174
• Icefall Burial — An improved version of Loa’s technique used to trap him during training. 25
• Ice Umbrella — An ice shelter Kuzan makes to shield the viewing stand from the heat of Loa and Kizaru’s clashing attacks. 181

Six Powers and Haki

Kuzan can use advanced Marine combat techniques in addition to his Devil Fruit.

• Used Soru to evade Loa’s Ice Coffin during his surprise test. 20
• Uses Observation Haki during sparring and battlefield assessment. 25
• His speed and reactions far exceed Loa’s temporary enhancement state. 25
• Is capable in close combat without relying solely on elementalization; he can shatter a broad layer of ice with a stomp forceful enough to shake the nearby fortress. 235
• Even Kuzan’s Observation Haki cannot reliably track Kaido’s evasive movement in his powerful Second Tier form. 391

Combat Instruction

Kuzan possesses practical expertise in both Devil Fruit development and combat fundamentals.

• Emphasizes concise movements, immediate reactions, proper evasion, and attacks with sufficient power. 25
• Teaches Loa to treat freezing as a battlefield-control and defensive power rather than relying on it as simple single-target offense. 24
• Advises reinforcing vital areas instead of wasting stamina on full-body Ice Armor. 24
• Can identify the weaknesses in Loa’s techniques and reproduce them in a more effective form. 25
• Tests Loa’s new defenses before trusting them in dangerous combat and continues assessing his progress after their initial month of training. 32 101 102

Power Progression

Relationships

• Loa — Mentor, trainer, and reluctant “teacher.” Kuzan tests Loa, provides nightly instruction, and tacitly accepts him as a disciple despite denying the title. Their later duels become a familiar rivalry; Kuzan notices when Loa conceals information but generally gives him room to explain himself. He is willing to sacrifice himself to protect Loa and Kizaru during their confrontation with Ulysses. 20 24 31 235 316 409
• Zephyr — Former teacher and fellow mentor to Loa. Their relationship combines familiarity, mutual respect, and frequent arguments over Kuzan’s laziness and teaching methods. Kuzan respects Zephyr’s right to leave Headquarters and later takes charge of the Elite Camp during its restructuring. 15 20 31 254 256
• Sengoku — Superior who assigns Kuzan to help develop Loa’s abilities and later permits him to train Loa daily. Kuzan eventually succeeds him as Fleet Admiral. 17 29 665
• Arudo — A recruit Kuzan once saved. Arudo idolizes Kuzan and challenges Loa after believing Kuzan has accepted a new disciple. 22
• Kizaru — Fellow Admiral and frequent participant in Kuzan’s banter. Kuzan bargains information about Loa for relief from Kizaru’s missions; they later fight together against Kaido, and Kuzan shields the wounded Kizaru from Ulysses. 170 382 393 409
• Akainu — Fellow Admiral whose magma counters Kuzan’s ice and whose approach to justice differs sharply from his own. Their rivalry becomes a conflict over the Marines’ leadership and the World Government; Kuzan later states that he trapped and killed Akainu. 170 315 667 668 753
• Tsuru — Senior Marine who sees through Kuzan during the crisis following Sengoku’s death but nevertheless entrusts the Marines to his leadership before requesting retirement. 667
• Kane and Ain — Kuzan promises the retired Major Kane that he will keep Ain out of the coming war and allow her to live with Zephyr. 601

Story Role / Major Arcs

Marineford Arrival

Kuzan prevents Loa’s uncontrolled ice aura from causing casualties at Marineford and evaluates him as an unusually powerful but unpolished recruit. 15

Loa’s Training

Kuzan ambushes Loa as a combat test, then begins nightly instruction in freezing abilities. He identifies Loa’s major problems as crude control, instinctive fighting, and poor formal combat experience. 20

He later arranges Loa’s spar with Arudo to expose his weaknesses and follows through with detailed tactical instruction after Loa wins. 22 24

Combat Assessment

Kuzan secretly accompanies the assessment expedition to observe Loa. He confidently reveals that Loa’s short-lived transformed state can reach Marine Headquarters vice-admiral-level strength, taking evident pride in his student’s growth. 29 31

Departure for East Blue

Before leaving for the East Blue, Kuzan tells Loa to continue training and entrusts Zephyr with Loa’s further development. He believes Loa must eventually follow his own path rather than remain dependent on a mentor. 35 36

Return and Elite Camp Instruction

Kuzan returns from his East Blue mission and tests Loa in another destructive spar, finding that his former student has improved enough to demand a serious response. He also questions Loa about crippling CP9 agents. Later, when Zephyr prepares to leave Headquarters, Kuzan calms the Elite Camp and assumes its instruction during restructuring. 101 102 254 256

Loa’s Graduation and Later Trust

During Loa’s unprecedented tenth graduation match, Kuzan is relieved that Kizaru, rather than Akainu, will face him because magma would counter Loa’s ice. He contains some of the battle’s collateral damage with his own ice. Kuzan later continues sparring with Loa and grows suspicious of his claims about Jones. When Loa explains his contingency plan, Kuzan warns him to be careful without demanding that he abandon it. 170 174 235 315 316

Alabasta and the Battle with Kaido

Kuzan arrives in Alabasta to reinforce Loa’s operation. After helping manage a civilian shelter crisis, he joins Loa and Kizaru in confronting Kaido. He directs their efforts toward restricting Kaido and wearing him down, refuses to abandon nearby civilians, and helps exploit an ice growth lodged near Kaido’s heart. Kaido ultimately escapes. 378 383 391 393 396

During a subsequent pirate attack on their departing fleet, Kuzan suffers a severe abdominal wound while shielding Loa and Kizaru from Ulysses’s Crimson Blood Prison. He offers to remain behind so Kizaru can carry Loa to safety. 403 409

Fleet Admiralty and the Marine Crisis

After the Paramount War, Kuzan becomes Fleet Admiral. Akainu, backed by World Government forces, publicly accuses him of forcing Sengoku from office and poisoning him. Kuzan disputes Akainu’s case on evidentiary and legal grounds as fighting breaks out among divided Marines. Tsuru, though aware that Kuzan has concealed his actions, chooses to trust him with the Marines’ future. 665 667 668

Kuzan later meets visiting Marines from another world, including another version of himself. He explains that his world’s Marines separated from the World Government and tells the visitors that he set a trap for Akainu and killed him, connecting their conflict to Sengoku’s death. 752 753
