Fourth Tier 385 First Release pushes Dragon Body beyond 80%, greatly increasing his strength and magic during his battle with Kaido; Loa fears the accompanying changes may be irreversible. 385
World Ascension and return 671, 672 After the Tremor-Tremor Fruit’s power fuses with his soul, Ivy raises the One Piece World’s limits so it can accommodate his power. Loa returns to his body and uses a vast Mass Dispel to calm the Undead Legion. 671 672
Level 90 691 Despite reaching level 90 and fully integrating his Dragon Body, Loa considers himself unready to challenge Poseidon alone and seeks powerful allies. 691 693
Resurrection revealed 770 Discovers that the defining feature he brought from World of Warcraft was resurrection. He returns at full strength after being killed, including after Poseidon destroys his body. 770

Background

Loa was preparing to play games and eat instant noodles in his original world when he lost consciousness and awakened alone on a deserted island. With no sign of civilization, he improvised to find food, discovered abnormal strength and endurance, and received a blue status interface identifying him as an “Ice Dragon Slayer.” 8

Initially dependent on coconuts, Loa learned that his growth system consumed extraordinary amounts of biological energy. He progressed by hunting the island’s wildlife, preserving meat with ice, building a cave-based shelter, and eventually “eating an island into poverty.” Isolation changed him from a frightened gaming shut-in into a quiet, capable hunter, while repeated use of Dragon Slayer Magic strengthened his body. 10

After discovering that he had arrived in the world of One Piece, Loa annihilated the Scissor Pirates with Ice Dragon’s Roar to gain the Marines’ attention and secure a way off the island. Vice Admiral Momonga brought him aboard, where Loa concealed his Dragon Slayer Magic by claiming to have eaten a Mythical Zoan Devil Fruit. 11 12

Loa joined the Marines to gain protection, formal combat training, and access to Haki, which he considers necessary to survive in the world. 13

Loa maintained the Devil Fruit explanation even after senior Marines discovered that Seastone cuffs did not weaken him. He feared that revealing magic’s existence would make him a target before he could defend himself against the world’s major powers. His apparent immunity let him unlock the cuffs with ice, but he continued to insist that he was a Devil Fruit user. 250

Loa later learned that his Dragon Body came from Ivy, who had once been known as Edith and Poseidon. According to Aokiji’s account to the Marines, Poseidon split her body, power, and soul into two halves: the impartial side associated with Loa and a destructive counterpart sealed beneath Mary Geoise. Loa learned that the voice he had heard during an earlier breakthrough belonged to that counterpart, not Ivy. 662 693 747 770

Appearance

Loa normally appears human, though his Dragon Body steadily increases his physique and physical presence. During breakthroughs and transformations, his draconic traits become visible. 10 40

  • Blue diamond-shaped markings form around both wrists after his first system upgrade. 9
  • A major breakthrough briefly gave him a taller, more muscular body, pale-blue scales, sharp nails, and golden vertical pupils. 10
  • First Release covers him in blue scales and produces claws, bone spikes at his elbows and knees, bat-like wings, and golden slit pupils. 32 33
  • Uncontrolled pseudo-dragonification can tear apart his Marine uniform as scales and wings erupt from his body. 40
  • Intensive Six Powers training increases his height considerably; later, a crimson scar running from his left eye to his jaw adds to his intimidating appearance. 58 185
  • He can assume a massive dragon form or a roughly twenty-meter-tall Dragon Person form. 747 750

Personality

Loa is practical, adaptable, and irreverent. Faced with starvation and isolation, he prioritizes survival and improvement, whether by improvising with his clothes, hunting enormous beasts, or exploiting the system’s rules. His gaming and webnovel experience shape how he interprets new abilities, often leading him to approach danger with jokes rather than panic. 8 9 24

He is also mischievous and frequently disregards military decorum. He weaponizes ice to evade punishments, prank fellow recruits, and provoke his instructors; his carelessness repeatedly causes collateral damage. 21 27 34

Despite becoming desensitized to killing during his isolation, Loa retains a capacity for respect and reflection. After defeating the Silverback Great Ape, he recognizes it as a worthy warrior, gives it a burial, and treats its death as a solemn turning point. 12 33

Loa’s ambition is to become the world’s strongest person. He is skeptical of institutional justice, believing that “justice” is often determined by the victorious side rather than by any fixed moral truth. 36

His loyalty to comrades can override caution: he defends injured Elite Camp members against CP9, then takes Kuzan’s warning seriously when told that the World Government could retaliate against his friends. On Hisville, he puts civilian rescue ahead of his mission rating. He can also be ruthless, using threats to secure cooperation and treating allies’ loyalty as conditional when he believes the stakes demand it. 72 93 102 151

Loa’s later decisions reflect both ambition and an awareness of his limits. He challenges powerful opponents to test himself, but, when faced with Poseidon, seeks a coalition rather than trusting his own strength alone. 212 654 691 693

Abilities & Skills

Ice Dragon Slayer Magic

Loa’s primary magic grants him a dragon-like constitution, ice-based offensive techniques, heightened physical ability, and the potential to transform through Dragon Force. His power is not a Devil Fruit, though he presents it as one to the Marines. 9 12

  • Ice Dragon’s Iron Fist — Coats his fist in Ice Dragon power, combining blunt force with freezing effects; used to hunt giant boars and finish the Silverback Great Ape. 9 10 33
  • Ice Dragon’s Roar — Fires an icy storm from his lungs through a magic circle. It can devastate pirate formations, generate hailstorms, and freeze large areas, but early use lacked precision. 11 19
  • Ice Dragon’s Wing Attack — A high-output Dragon Slayer technique available after reaching the Second Tier; later used to create the Silverback Great Ape’s grave. 13 33
  • Ice Bomb: Rapid Fire — Repeated explosive ice projectiles used to suppress the Silverback Great Ape. 31
  • Can recover strength by consuming ice after exhausting himself. Eating ice restores stamina and magic, but does not directly heal injuries; his body’s own recovery accounts for rapid wound closure. 33 79
  • His Dragon Slayer constitution causes severe motion sickness in vehicles, especially ships. 12 28
  • Later develops Dragon Slayer Secret Arts: Land of the End and Cosmic Descent. 171 654

Ice-Make Magic

After reaching the Second Tier, Loa gains the ability to create and shape ice directly with magic rather than relying on existing water or cold air. 13

  • Forms airborne ice platforms for movement and short-range flight. 17
  • Creates weapons and battlefield-control constructs, including ice swords, spears, wolves, trees, umbrellas, and coffins. 20 24 34 46
  • Heavy Armored Lancer — Produces an ice spear capable of piercing the Stone Drum Bull’s steel-hard defenses. At maximum output, a 3,000-Magic-Power spear tears through multiple concrete basement floors. 30 142
  • Great Serpent — A defensive/offensive construct designed to absorb and disrupt Kuzan’s structured ice attacks. 27
  • Thousand Forest Thrust — Summons numerous armor-piercing ice spikes with improved precision. 45
  • Ice Armor — A layered defensive technique. His later Type 17: Spider variant adds weaponized icy limbs for offense and defense. When badly injured against Kizaru, he reshapes the armor into Model 17: Powered Exoskeleton to support his movement. 32 45 178
  • Loa can use Ice-Make Magic freely, but considers his control over Dragon Slayer Magic comparatively crude. 39 45
  • Aokiji later exploits his familiarity with Loa’s ice by mixing his own into Ice Coffin, weakening the defense enough for Garp to break through. 511

Dragon Force and Dragon Body

Dragon Force enhances Loa’s Dragon Slayer Magic but progressively alters his body. Dragon Body represents his compatibility with that power, with greater compatibility improving his physical qualities. Loa later learns that the Dragon Body itself came from Ivy. 9 40 770

  • Dragon Force begins transforming the user’s body once it exceeds 0%; extreme accumulation risks full dragonization. 9
  • Dragon Body enhances strength, endurance, durability, recovery, and instincts. 9 26
  • Repeated use of Dragon Force increases its percentage permanently; Loa treats this as a serious risk. 27 33
  • His Dragon Force reaches 6% after the Silverback Great Ape battle and subsequent upgrade. It later reaches 9% even though he has spent the intervening month concentrating on physical techniques. 39 64
  • Dragon Might released during First Release can frighten wildlife over a wide area, indirectly triggering a beast tide. After learning Life Return, Loa can bring out Dragon’s Might without transforming. 34 95
  • Dragon Body can warn him of danger that his Observation Haki misses, as when Yasopp fires a Seastone bullet at him. 210 211
  • First Release eventually drives Dragon Body beyond 80% and into the Fourth Tier, bringing immense power alongside changes Loa fears may be irreversible. 385

First Release

First Release is Loa’s self-developed method of forcibly activating Dragon Force. By using Ice-Make Magic inside his own body, he causes himself to absorb ice-element magic and enter a temporary dragon-human combat state. 33 34

  • Greatly increases his strength, speed, durability, recovery, and combat instincts. 32
  • Lets him physically overpower the Silverback Great Ape after his normal ranged attacks prove insufficient. 32 33
  • Temporarily disables Ice-Make Magic after activation, though Dragon Slayer Magic remains usable. 33
  • Its bloodthirsty impulse can impair his reasoning. 33
  • Accelerates Dragon Force growth, making it dangerous to use except in critical situations. 33
  • Against Kaido, an advanced use gives Loa enough strength to throw him, but leaves Loa concerned about permanent dragonization. 385

Awakening: Pseudo-Dragonification

A system-generated skill unlocked at Second Tier, Sixth Level, apparently in response to Loa’s creation of First Release. 40

  • Temporarily awakens Dragon Force.
  • Raises Dragon Body compatibility by one stage.
  • Strengthens Dragon Slayer Magic and magic recovery.
  • Consumes no magic power while active. 40
  • Its emergence confirms that Loa’s self-created techniques can alter the system’s available abilities. 40

Physical Combat and Survival

Loa’s Dragon Body gives him extraordinary baseline strength and endurance even without Haki or Six Powers training. 10 17

  • Can run one hundred 2,000-meter laps while maintaining a controlled pace and finishing near the front. 16
  • Can break steel with brute force after a major Dragon Body threshold. 27
  • Uses improved Ice Armor and focused protection around vital areas to withstand lethal attacks. 49
  • Learned hunting, fire-making, food preservation, shelter use, and salt collection while stranded alone. 10
  • Initially lacks Haki and acknowledges that his close-combat fundamentals remain underdeveloped compared with experienced fighters. He later trains in both Haki and the Marine Six Powers. 13 33 56 100

Marine Six Powers and Haki

Zephyr teaches Loa the Six Powers as methods of controlling his body, rather than simply as attacks. Dragon Body supplies the physique needed to learn them rapidly, while Life Return gives him fine control over his strength and contributes to his healing. 56 58 79 95

  • Masters Finger Pistol, Soru, Geppo, and Tempest Kick in twenty days. He develops Eight Maidens, a rapid clawing extension of Finger Pistol, and Three-Day Moon, which combines successive Tempest Kicks with high-speed movement. 58
  • Later stabilizes Iron Body through repeated impact training and continues working on Kami-e. He eventually learns Life Return and all six techniques. 86 95 107
  • Learns basic Armament Haki in about a week and reaches Hardening in roughly half a month. Its initial growth stalls because the dragon-transformed parts of his body reject ordinary Haki. 100 103
  • Develops a distinctive blue-black Armament Haki by combining it with ice-aspected Dragon Slayer magic and a small amount of Dragon Force. He also begins using Observation Haki in combat. 104
  • Awakens Conqueror’s Haki while fighting Whitebeard. His earlier Dragon’s Might is a separate power; Shanks’s Conqueror’s Haki decisively overpowers it in their first confrontation. 211 212 652

Death Power, Time, and Resurrection

Loa’s later powers extend beyond conventional ice magic. He creates and commands Undead, can give them power through his Dragon Slayer Magic, and possesses freezing abilities that eventually affect time. 432 473 651

  • Builds an Undead Legion that includes resurrected fighters. He can enchant a weapon to raise the dead and recharge it for further use. 432
  • Freezes time around Marine Headquarters for an estimated ten minutes, protecting those caught near his battle with Whitebeard from their opening clash. 651
  • After the world’s ascension, uses Mass Dispel across Turtle Island to end the Undead Legion’s frenzy. 672
  • Discovers that the ability he brought from World of Warcraft was resurrection, rather than the source of his Dragon Body. Death leaves behind a corpse that Poseidon cannot absorb, while Loa returns at full strength. 770

Relationships

  • Vice Admiral Momonga — Loa’s first Marine contact and rescuer from the deserted island. Momonga recruits him, repeatedly disciplines him, and remains personally concerned for his safety despite frequent exasperation. Later, although he cannot match Loa’s strength, their familiarity persists when Loa asks him to spare Luffy. 12 13 34 36 556 557
  • Kuzan / Aokiji — Loa’s principal ice-power mentor and sparring partner. Kuzan publicly resists the “teacher” title but trains Loa nightly, tests his techniques, and ultimately treats him as a disciple. He warns Loa that harming CP9 may endanger his comrades, privately resolves to protect him, and later explains Loa’s origins to senior Marines. 20 24 31 102 693
  • Zephyr — Chief instructor and mentor figure. Zephyr recognizes Loa’s potential, disciplines his recklessness, and intends to train him toward Admiral-level strength. He teaches Loa the Six Powers and Haki, then acknowledges that Loa has learned all he can teach him. Loa remains deeply attached to him and seeks to help him confront his past. 15 35 36 56 100 107 753
  • Ms. S — Marine cafeteria cook and Loa’s eating-contest rival. She later helps plan meals suited to his extreme appetite. 19 27
  • Arudo — Elite Camp recruit and recurring rival. Loa defeats him through battlefield control, while Arudo continues seeking opportunities to challenge him. 22 24 46
  • Silverback Great Ape — Land Beast hunted by Loa for food. Their brutal two-hour fight leads Loa to respect it as a warrior and bury its body after killing it. 31 33
  • Garp — Vice Admiral who offers to take Loa as a disciple, primarily to irritate Zephyr. Loa rejects him and argues that Zephyr is the better instructor. 44
  • Sengoku — Fleet Admiral who becomes concerned by the scale and nature of Loa’s potential, including the possibility that his ice may affect time or space. He later keeps Loa’s rapid Haki progress secret and retains him as a vice admiral despite punishing his destructive conduct. 39 40 103 250
  • Tony Mill — Fellow Elite Camp recruit and swordsman. Loa protects him during the CP9 confrontation, searches for him after the fighting on Hisville, and warmly welcomes him home after Tony’s time in the New World. 79 93 355
  • Robin — Loa’s partner, whom he protects from those pursuing her. She cares for his body while his soul is in Between Dreams and is furious when the danger surrounding his return nearly kills her. Loa later expresses a wish to start a family with her. 429 662 672 691
  • Ivy / Edith — The former Poseidon, whose body became the source of Loa’s Dragon Body. She treats him as her son, helps him return from Between Dreams, and guides him through the consequences of World Ascension. 662 671 672 770
  • Poseidon — Ivy’s sealed, destructive counterpart and Loa’s principal later adversary. Loa assembles allies to face her and eventually discovers his resurrection ability through their repeated fights. 693 747 770
  • Jones — Initially Loa’s enemy on Kuriswia, then a powerful subordinate whom Loa sends on missions and uses to extend his influence. Loa considers their alliance conditional and threatens consequences for betrayal. 151 158 320 691
  • Whitebeard — Loa gives him a restorative so they can fight at full strength during the Paramount War. Their destructive duel tests Loa’s endurance and coincides with the awakening of his Conqueror’s Haki. 651 652 654

Story Role / Major Arcs

Transmigration and Island Survival

Loa awakens alone on an unknown island, discovers his system and Ice Dragon Slayer Magic, then survives by hunting and consuming the island’s creatures. He reaches the Second Tier before finally encountering Marines and learning that he is in the world of One Piece. 8 10 11

Entry into the Marines

After eliminating the Scissor Pirates, Loa uses Momonga’s warship to escape the island. He hides the origin of his magic behind a Devil Fruit cover story, joins the Marines for access to Haki training, and enters Zephyr’s Recruit Training Camp. 12 13 15

Marineford Training

Loa’s abnormal strength quickly makes standard recruit exercises inadequate. Kuzan begins teaching him ice-power applications and combat control, while Zephyr focuses on his weak fundamentals. During this period, Loa defeats Arudo, develops Ice-Make techniques, and discovers that combat and insight can raise his Energy Value more effectively than food. 17 24 26

Elite Assessment

During the Combat Assessment on a Calm Belt island, Loa leads other recruits briefly before hunting the Stone Drum Bull and then pursuing the Silverback Great Ape for food. His battle with the ape triggers a beast tide that suspends the assessment and earns him the resentment of much of the Recruit Camp. 29 30 31 34

Silverback Great Ape Battle

Loa’s ranged attacks seriously wound the Land Beast but fail to stop its close-range assault. He activates First Release, fights the ape in a savage dragon-human form, and eventually kills it with Ice Dragon’s Iron Fist. He receives 1,000 assessment points and buries the ape in an ice-sealed grave. 32 33

Mass Recruit Challenge

As punishment for the earlier beast tide, Zephyr requires Loa to defeat every challenger before entering the Elite Camp. Loa develops stronger Ice-Make Magic and confronts recruits, Elite Camp members, and top-ranked fighters at once while senior Marines observe his growth. 35 45 46 49

Elite Camp and Hisville Mission

Zephyr begins instructing Loa in the Six Powers and Haki. Loa masters four of the Six Powers with exceptional speed before being assigned to lead Arudo, Mingde, and Tony on a field voyage. On Hisville, he orders the crew to aid civilians regardless of their mission score, fights the pirate Beard, and searches for Tony after the battle. 56 58 64 72 79

Back at Marineford, Loa stands up for injured Elite Camp members against Rob Lucci and CP9. Kuzan subsequently warns him that the political consequences of crippling Government agents could fall on his friends. Loa’s training culminates in Armament Haki, a method of combining it with Dragon Force, and graduation tests that Zephyr judges to show Admiral-level strength. 93 102 103 104 112

Vice Admiral and Break with the Marines

As a Marine vice admiral, Loa undertakes increasingly consequential missions, commands forces, and confronts major pirates. His powers and tactics broaden, but he recognizes after fighting Kizaru that possessing an Admiral’s overall strength is not the same as mastering each of his many disciplines. He continues concealing the magical source of his abilities even when his immunity to Seastone raises questions among Marine leaders. 142 184 212 250 334

Loa later leads the Undead Legion outside the Marines. He raises fallen fighters into its ranks and uses Turtle Island’s position at the entrance to the New World to curb piracy. After obtaining Big Mom’s Road Poneglyph, he broadcasts that anyone seeking to become Pirate King must take it from him. 432 507 545

Paramount War and World Ascension

Loa fights Whitebeard at Marineford, freezing time around the headquarters to protect others from their clash. He restores Whitebeard to his physical prime, awakens Conqueror’s Haki during their battle, and endures the awakened Tremor-Tremor Fruit’s attacks. His resulting power exceeds what the One Piece World can contain, leaving his soul in Between Dreams while Robin watches over his body. 651 652 654 662

Ivy helps Loa fuse the Tremor-Tremor Fruit’s power with his soul and raises the world’s limits so he can return. Back on Turtle Island, he calms his frenzied Undead with Mass Dispel and learns of the changed political order. Recognizing that Poseidon may still exceed him in strength, he begins recruiting other powerful fighters for the coming battle. 671 672 691 693

Confrontation with Poseidon

Loa discovers that the voice heard during his Third-Tier breakthrough came from Poseidon. After the battlefield shifts into a Mirror World, he searches for her while organizing allies and local forces. During their fight, he learns that the power he brought from World of Warcraft is resurrection: even after Poseidon kills him and consumes his remains, he returns to challenge her again. 747 751 757 770
