Background

Zhao Hai was Qian Ye's best friend on Earth. While playing a One Piece mobile game in his dormitory, he transmigrated into the Pirate World and awakened as a menial Marine recruit at East Blue's 16th Branch. Captain Nezumi routinely exploited him for labor and even withheld his meals 1.

The Cross-Border Brothers Mutual Aid Group reunited Zhao with Qian Ye, who had transmigrated into the Naruto world. Recognizing that rare powers were beyond their immediate reach, the pair traded accessible knowledge instead: Zhao stole the Marine Headquarters Basic Physical Training Outline from a branch warehouse, while Qian Ye sent him chakra-refinement instructions and the Three Body Techniques 2.

Nezumi later attempted to make Zhao a scapegoat for his partnership with Arlong. Zhao defeated two arresting Marines with chakra-enhanced punches, disguised himself as Nezumi's adjutant, stole the captain's hidden ledger, and faxed its evidence directly to Marine Headquarters. Garp responded to the report, arrested Nezumi, noticed Zhao's unfamiliar energy, and took him aboard the Dog-Head Warship for training 12.

Under Garp, Zhao endured extreme physical conditioning while building a combat style around chakra, the Six Powers, Haki, Sea King meat, and the Yin Seal. His access to Pirate World resources also made him Qian Ye's principal supplier of Sea King meat and a recipient of ninja-world items such as Military Ration Pills, Explosive Tags, and jutsu instructions 24 25 57 76.

Appearance

Zhao Hai is a teenage Marine trainee with a physique hardened by Garp's training. He usually wears an unranked Marine uniform despite possessing abilities far beyond an ordinary grunt's 57 108.

• His body is visibly muscular enough to endure one-finger push-ups under a two-ton iron ingot 57.
• In Storm Dragon form, fine azure scales cover his body, accompanied by faint azure currents resembling a forming storm 140.
• He carried a Marine uniform reduced to strips after Golden Lion Shiki's sword strike 139.

Personality

Zhao is vulgar, boastful, and highly comedic, frequently calling Qian Ye “son” while accepting being called “Godfather” in return. His banter masks genuine concern: he repeatedly supplies Qian Ye with food and resources, warns him about dangers such as Orochimaru and Danzō, and immediately activates Garp's emergency commission when Qian Ye is threatened 24 25 67 98.

He is also pragmatic and unusually self-aware about his path. Although he discovered two exceptionally valuable Devil Fruits, he initially rejected both because he wanted to develop through hand-to-hand combat, the Six Powers, chakra, and the Eight Gates rather than sacrifice his ability to swim 84 85. He only consumed the Storm Dragon Fruit when Shiki's overwhelming strength left survival as his priority 140.

Abilities & Skills

Chakra Techniques

Zhao learned chakra refinement and basic ninja techniques from Qian Ye, adapting them to the Pirate World's combat system.

• Used the Transformation Technique to impersonate Nezumi's adjutant and infiltrate Nezumi's office 12.
• Reinforces his muscles and acupoints with chakra to increase explosive power and reduce training damage 40.
• Can create a chakra membrane around his body, allowing him to cross corrosive miasma with reduced injury 84.
• Can walk or run across water for short periods through precise force control; he later explained the principle to Garp 67 102.

Six Powers

Garp trained Zhao in all six Marine Six Powers, which Zhao combines with chakra reserves and acupoint stimulation 40.

• Geppo — Allows sustained aerial movement; Zhao used it to evade Smoker and maneuver through Shiki's collapsing floating island 108 144.
• Tempest Kick — Produces vacuum slashes. His Tempest Kick: Chaos fires numerous crescent-shaped slashes, though it could not meaningfully damage Shiki's massive stone constructs 108 142.
• Iron Body — Withstood a pirate captain's full-power cleaver strike without breaking Zhao's skin 45.
• Finger Gun — Uses concentrated striking force; Zhao later enhanced it with Armament Haki to injure Shiki internally 45 143.
• Life Return — Began learning the technique after mastering the Six Powers 40.

Yin Seal

Qian Ye gave Zhao the instructions for the S-rank forbidden Yin Seal, which Zhao learned despite the painful formation process 57.

• Stores excess chakra generated from Sea King meat instead of allowing it to dissipate.
• Stabilizes chakra output during high-intensity physical exertion.
• Provided the reserve needed for Zhao to catch a five-ton boulder and later power his decisive strike against Shiki 57 145.

Armament Haki

Zhao developed Armament Haki under Garp's guidance, eventually using it for both precision and offense.

• Coats blades or limbs with Haki rather than relying solely on physical strength 116.
• Focuses Haki into his fingertips to increase Finger Gun's penetrating power 143.
• Coated his leg in Armament Haki for Tempest Kick: Secret Art—Battle Axe, the strike that hit Shiki's embedded rudder 145.

Storm Dragon Fruit

Zhao consumed the Mythical Zoan Storm Dragon Fruit while facing Golden Lion Shiki. The fruit had been identified by the mutual-aid system as granting storm-dragon transformation, wind and lightning control, regeneration, and enhanced physical strength 85 140.

• Manifested azure scales that protected him from debris and attacks.
• Its regeneration closed his severe chest wound enough for him to rejoin the fight against Shiki 140 143.
• Regeneration could not fully overcome the damage from Shiki's Haki-infused sword aura or restore Zhao's exhausted stamina 140 144.

Equipment & Resources

• Marine Headquarters Basic Physical Training Outline — Stolen from the 16th Branch warehouse and traded to Qian Ye; it contained foundational information related to Marine movement techniques 2.
• Sea King meat — His principal training resource and the foundation of his high vitality and chakra reserves. He routinely transfers portions to Qian Ye 24 25.
• Rocks Pirates treasure — Discovered tens of billions of Beli in gold, jewels, and pearls within a hidden Rocks vault on Gal Island 84.
• Visual Den Den Mushi — Used to photograph himself at Loguetown's ruined execution platform after defeating Quick Blade Baskis 108.

Relationships

• Qian Ye — Best friend from Earth and fellow transmigrator. They exchange techniques, food, supplies, intelligence, and emergency support while constantly teasing one another 1 24 57 98.
• Monkey D. Garp — Mentor and personal master. Garp recognized Zhao's potential after the Nezumi incident, personally trains him, publicly calls him his disciple, and protects him from other Marines 12 108.
• Hatake Sakumo — Cross-world rescuer and combat partner. Sakumo was hired to save Zhao from Shiki; together they severely injured and defeated the pirate during a three-minute employment mission 139 145.
• Monkey D. Dragon — Attempted recruiter. Dragon sensed Zhao's unusual chakra and invited him to join the Revolutionary Army, but Garp rejected the offer and Zhao remained with the Marines 115.
• Smoker — Brief opponent in Loguetown. Zhao evaded Smoker's smoke attacks with Geppo and dispersed his body with Tempest Kick, though he avoided a decisive clash before fully developing Haki 108.
• Golden Lion Shiki — Enemy who nearly killed Zhao and attempted to recruit him into the Flying Pirate Crew. Zhao refused, later helping Sakumo exploit Shiki's old rudder wound 140 145.

Story Role / Major Arcs

Nezumi Incident

As an expendable 16th Branch recruit, Zhao was targeted for execution by Nezumi. His chakra-based infiltration exposed the captain's Arlong ledger and directly led to Nezumi's arrest by Garp 12.

Garp's Training

Zhao became Garp's disciple and rapidly developed the Six Powers through brutal conditioning, chakra-based acupoint stimulation, and Sea King meat recovery. His growth transformed him from a branch errand boy into a Marine fighter capable of defeating pirates and challenging Smoker's mobility 40 45 108.

Cross-Border Emergency Support

Zhao brokered Garp's employment through the Cross-Border Employment System by offering the Water-Surface Walking Training Method as compensation. When Qian Ye faced the Two-Tails, Zhao activated the three-minute commission that brought Garp into the Naruto world 67 98.

Rocks Pirates Vault

Following a treasure map recovered from a pirate ship, Zhao crossed Gal Island's toxic miasma and uncovered a hidden Rocks Pirates reserve. The vault contained immense wealth and the Kinetic Energy and Storm Dragon Devil Fruits, the former of which was transferred to Qian Ye 84 85 86.

Battle Against Golden Lion Shiki

Zhao encountered Shiki and was nearly killed despite consuming the Storm Dragon Fruit. Qian Ye hired Sakumo through the employment system, and Zhao coordinated with the White Fang throughout the collapsing-island battle. After Sakumo broke through Shiki's defenses and forced his head back, Zhao landed the decisive Haki-enhanced Tempest Kick on Shiki's rudder wound 139 145.
