Background

Ulti and her younger brother Page One were brought to Kaido’s feast as descendants of one of Kaido’s old acquaintances. Their father had already died, leaving Page One as Ulti’s only family; she had promised to protect him. 43 50

Initially, Ulti rejected Yamato’s outstretched hand and refused her offer of friendship. Her hostility was rooted in the siblings’ precarious place on Onigashima, where adult pirates freely preyed on weaker members of the Beasts Pirates. 43 51

Appearance

At age fifteen, Ulti is a petite, slender girl standing under 1.7 meters tall, making her physical power easy to underestimate. 326

• Wore a mask as a nine-year-old. 63
• Her hybrid transformation gives her a swollen, reinforced forehead, a long tail, and yellow scales over her limbs. 326
• Her full Beast Form is a Pachycephalosaurus. 273 549
• She has also demonstrated an unexplained colossal growth state. 130

Personality

Ulti is confrontational, stubborn, and quick to take offense, especially when others call her “Little Ulti” or underestimate her. She initially responds to Yamato’s friendship with open hostility, later accepting it only with visible embarrassment. 43 57 308

Her defining trait is her intense devotion to Page One. She treats “Pay-tan” as an exclusive nickname, reacts violently to anyone she thinks may hurt or take him away, and repeatedly places herself between him and danger. 44 50 59 346 This protectiveness often becomes possessive as Page One grows more independent. 63 346

Despite her rough manner, Ulti is deeply loyal to the Sirius Pirates and cares for her crewmates. Her friendship with Yamato develops through training and sparring, though she continues to express affection through insults and arguments. 57 308

Abilities & Skills

Ancient Zoan Transformation

Ulti can transform into a Pachycephalosaurus or a human-beast hybrid through her Ancient Zoan Devil Fruit. 53 273 326

• Her dinosaur form enabled her to pursue and defeat pirates who had previously abused her and Page One. 53
• Her hybrid form enhances her forehead, tail, speed, and physical striking power. 326
• As a child, her small size and lack of experience still left her disadvantaged against adult fighters such as Lao G. 155

Headbutts and Mace Combat

Ulti combines head-first charges with a mace-style club.

• Ulti Headbutt — A reinforced forehead strike powerful enough to break bones and incapacitate opponents. 53
• Ulti’s Mace — Her named mace clash against Lao G. 155
• Ulti Meteor Hammer — A descending mace strike described as carrying mountain-like force. 326

Haki

Ulti uses Haki to reinforce her attacks and defenses.

• She learned Flowing Haki and applied it through her mace against Urouge. 326
• Her Haki later repelled Onigumo’s Haki-coated swords before she counterattacked. 549

Colossal Growth and Black Flames

During the escape from Onigashima, Ulti displays power far beyond her usual dinosaur form.

• Her enlarged body dwarfs the Ancient Giant Tribe and launches King away with a single palm strike. 130
• She exhales black flames across the rooftop, preventing Queen from directly pursuing her group. 130
• Despite her size, she covers thousands of meters per leap while carrying Page One, Jack, and others. 130

• Stolen katana — Used briefly as a five-year-old to slash a pirate while defending Page One. 45

Relationships

• Page One — Her younger brother and the person she values above all else. Ulti calls him “Pay-tan” and is fiercely possessive of their sibling bond. 44 50 59 346
• Yamato — Initially rejected by Ulti, but later becomes her first friend. The two train and spar together regularly. 43 57 308
• Sirius — A crewmate and mentor whom Ulti frequently insults as a “scoundrel.” He teaches her basic subjects, encourages her strength, and entrusts combat to her. 59 200 325
• King — Assigned as Ulti and Page One’s trainer after Kaido permits them to retain their Devil Fruits. 53
• Queen — Treated Ulti and Page One after their injuries, then manipulated them into learning about Kaido’s stored Devil Fruits. 51 53

Story Role / Major Arcs

Okuchi-no-Makami Game

Ulti and Page One enter Kaido’s battle royale hoping to win the Okuchi-no-Makami Fruit and escape being bullied by other pirates. When Page One is kidnapped afterward, Ulti endures a brutal beating rather than abandon him. 44 45 50

After Yamato and Sirius rescue them, Ulti refuses to let Yamato take revenge on her behalf. Queen then exploits her desperation for strength, leading the siblings to consume Ancient Zoan fruits from Kaido’s collection. Kaido accepts their decision and places them under King’s care. 51 53

Training and Departure from Onigashima

Ulti joins Sirius, Yamato, and the others’ demanding training. Even when exhausted, she carries Page One and continues running until her body gives out. 58 59

She later leaves Onigashima with the group, participates in their escape from Kaido and King, and becomes part of the Sirius Pirates after Sirius formally breaks from the Beasts Pirates. 130 132 142

Sirius Pirates Voyages

Ulti contributes to the crew’s early pirate flag design with Yamato and Page One. 144 She fights alongside Page One against the Donquixote Family, though her age and size leave her at a disadvantage against Lao G. 155

On the White Sea, she is selected to test Urouge’s request to measure the power of Blue Sea pirates. Her strength and Flowing Haki force Urouge to acknowledge the vastness of the world beyond his home. 325 326

Final War

During the large-scale conflict against the World Government, Ulti rampages through the battlefield in Pachycephalosaurus form. She overpowers Vice Admiral Onigumo and continues fighting alongside Page One, Maria, Bepo, Hiyori, and the allied forces. 549
