Background / History

Kyros became famous as a gladiator of the Corrida Colosseum, completing 1,000 consecutive victories while still nineteen. The World Government attempted to recruit him, while Kyros initially preferred remaining in Dressrosa and joining the Riku Royal Army 398. He later accumulated more than 3,000 undefeated matches and became known as Dressrosa’s legendary gladiator 1356.

As captain of the Riku Royal Army, Kyros was also entrusted with protecting the Agricultural College 1392. He is married to Scarlet and remained closely connected to the Riku royal family, regarding Dressrosa and his home as more important than the larger territory and title offered by the World Government 1432.

Kyros entered the second Myriad Worlds Top 100 Combat Power Tournament as Sea Star’s leading representative. He finished first in both the points round and the Swiss round, then defeated Renga and Yami-hime before overcoming Qin Su and Susanoo in the championship match 1356 1392 1403 1426 1427.

After winning, Kyros used his granted wish to obtain equipment suited to him. He rejected advanced Haki instruction and Great Swordsman insights, choosing instead to retain his longtime sword and acquire Incursio armor to better protect his family 1432.

Kyros later participated in operations across other worlds. During the assault on the Roman imperial palaces, he used Incursio’s invisibility and enhanced abilities to fight Awakened Beings and Dragon Descendants 1506. In the Hero World, he fought Fuhrer Ugly and later helped combat the Monster Association. After recognizing the overwhelming gap between his power and Tatsumaki’s, he decided to leave the Hero Association 2434.

Appearance

Kyros is a towering, heavily built swordsman who is listed as 298 centimeters tall at age thirty. He commonly wears a red cape and carries a long sword. When using Incursio, he appears in a full suit of combat armor with dragon wings and a transformed sword 1402 1506 2271.

  • Nearly two-meter-long sword carried across his back 1402.
  • Red cape used during the Top 100 Tournament 1403 1427.
  • Incursio armor with dragon wings and an armored transformation 2256 2271.
  • Red-backed Shrike forms the blade used with Incursio 1506 2419.

Personality

Kyros is calm, disciplined, and often quiet, preferring to observe an opponent’s techniques before acting. Although he wants to win, he is also interested in learning unfamiliar abilities from other worlds 1402.

He possesses a strong sense of justice. During his match with Hank, Kyros refused to deliberately force his opponent into a loss-of-control transformation merely to witness its power 1422. He respects an opponent’s resolve and is willing to defeat a determined warrior directly rather than accept an unearned surrender 1422.

Kyros is confident in his own potential but remains practical about his priorities. He chose protective equipment over advanced Haki knowledge because he believed stronger equipment would help him protect his family after Dressrosa’s political position changed 1432.

Abilities & Skills

Armament Haki

Kyros can coat his sword and body in Armament Haki. His blackened blade withstood and countered powerful attacks, and his Armament Haki was described as superior in quality to Yami-hime’s 1403 1426.

  • Reinforces his longsword for clashes with powerful weapons and bodies.
  • Supports his Flying Slashes and close-range sword attacks.
  • Helps him fight Awakened Beings while surrounded 1506.
  • His Haki is powerful, but he considers advanced Haki techniques something he can master later 1432.

Observation Haki

Kyros uses Observation Haki for precise battlefield awareness and evasive movement. Against Renga, he moved through a web of reflected sunlight with extremely small movements, avoiding every beam and deflecting unavoidable attacks at precise angles 1403.

  • Tracks attacks from multiple directions.
  • Assists him in avoiding Fuhrer Ugly’s attacks when the monster’s speed exceeds normal visual perception 2420.
  • Combines with swordsmanship to identify openings and counterattack.

Swordsmanship

Kyros is an exceptionally experienced swordsman whose skill was developed through thousands of duels. His experience against fighters from different worlds allows him to adapt to Swordsmen, Physical Arts users, Devil Fruit users, espers, and other combat styles 1426.

  • Uses high-speed Flying Slashes.
  • Can destroy multiple targets or projectiles with sweeping blade waves.
  • Deflected Renga’s concentrated sunlight and shattered his ice mirrors 1403.
  • Fought Yami-hime for nearly two hours in a pure contest of strength, technique, and Haki 1426.
  • Used Thunder Destruction Sword: Distant Thunder against Fuhrer Ugly 2420.
  • Used Thunder Destruction Sword: Super Tyrannosaurus Slash to sever Fuhrer Ugly’s head 2434.

Thunder Breathing

Kyros practices Thunder Breathing and incorporates it into his swordsmanship. The golden electrical currents shown around him are an illusion produced by the technique rather than actual electricity; their main purpose is to make his movements more spectacular 1422.

  • Increases the spectacle and presentation of his high-speed attacks.
  • Combines with Geppo and swordsmanship in aerial combat 1427.
  • Forms the basis of his Thunder Destruction Sword techniques 2420 2434.

Geppo

Kyros learned Geppo shortly before the championship match. The technique allows him to step through the air, giving him a way to pursue airborne opponents and fight above Qin Su’s water-filled arena 1426 1427.

  • Provides aerial movement without relying solely on Incursio’s wings.
  • Lets him maneuver through mist and over water.
  • Combines with Thunder Breathing during high-speed attacks 1427.

Incursio

Incursio: Operated Armor is an armor-type Teigu chosen by Kyros as his tournament prize. It substantially improves his physical abilities and can render him invisible 1432 1506.

  • Enhances speed and strength.
  • Grants invisibility, making Kyros difficult for Dragon Descendants and Awakened Beings to sense 1506.
  • Provides dragon wings for aerial movement 2256 2257.
  • Can release the power of Tyrande’s will as dragon-attributed energy 2434.
  • Its energy conversion is limited, forcing Kyros to reserve the dragon energy for a decisive strike 2434.

Dragon-Attributed Energy

Kyros learned to use dragon-attributed energy from a hunter associated with the World Ecological Association. When converted through Incursio, the energy can suppress an opponent’s regenerative ability 2434.

  • Used against Fuhrer Ugly’s powerful regeneration.
  • Must be applied decisively because Incursio cannot convert large amounts of the energy at once.
  • Enabled the final Super Tyrannosaurus Slash that killed Fuhrer Ugly 2434.

Endurance and Combat Adaptability

Kyros possesses exceptional stamina and has built his strength through prolonged combat. He can reportedly fight for at least a full day and night, and his tournament battles against Yami-hime and Qin Su lasted nearly two hours and more than an hour respectively 1403 1426 1427.

  • Continues fighting while heavily injured and exhausted.
  • Adapts to water-based, aerial, regenerative, and illusion-based opponents.
  • Combines Haki, Breathing, Geppo, swordsmanship, and Incursio rather than relying on a single power system.

Equipment / Weapons / Items

  • Longsword — Kyros’s longtime weapon, which he refused to replace after winning the tournament 1432.
  • Red-backed Shrike — Transforms into the sword Kyros uses with Incursio and can channel dragon-attributed energy 1506 2434.
  • Incursio: Operated Armor — Armor-type Teigu that enhances Kyros’s physical abilities, grants invisibility, and produces dragon wings 1432 1506.
  • Crimson cape — Kyros’s distinctive tournament garment, worn over his armor or combat clothing 1403 1427.

Relationships

  • Scarlet — Kyros’s wife and the eldest princess of Dressrosa. Protecting his family is one of the main reasons he sought better equipment 1357 1432.
  • Riku Doldo III — His father-in-law and king of Dressrosa. Riku supported Kyros’s decision to seek equipment rather than attempt to preserve the kingdom’s royal authority 1432.
  • Viola — Kyros’s sister-in-law; she and Scarlet watched his tournament victory from Dressrosa 1432 2434.
  • Doflamingo — Tournament authority who recognized Kyros’s potential as a King Duelist and granted his post-victory wish 1403 1432.
  • Jaka — Fellow warrior who taught Kyros Geppo before the championship match 1426.
  • Renga — Tournament opponent defeated by Kyros after an Ice Release battle 1402 1403.
  • Yami-hime — Semifinal opponent. Kyros defeated her after a prolonged duel and praised her swordsmanship and potential 1426.
  • Qin Su — Championship opponent and imperial prince. Kyros defeated Qin Su and Susanoo after an extended battle 1427.
  • Hank — Tournament opponent whose resolve Kyros respected despite Hank’s transformation and eventual defeat 1422.
  • Morgan William — Senior Hero Association figure whom Kyros protected and accompanied during operations 2418 2464.
