Luka

Overview

Luka is a character in Honkai: Star Rail. He is a key member of the resistance organization Wildfire in the Underworld of Belobog on the planet Jarilo-VI, as well as an undefeated martial artist and boxing champion at the Boulder Town Fight Club. Warm-hearted and driven by an intense sense of justice, he dedicates himself to protecting the people of the Underworld and serving as a beacon of hope for local children.

Appearance

Luka has bright blue eyes and short red hair with strands falling between his eyes, tied into a small ponytail at the back. His defining visual feature is his mechanical prosthetic right arm, which was temporarily upgraded to an Interastral Peace Corporation combat exoskeleton model known as Mamitu 17 Pro Plus before reverting to a spare older model. His attire consists of a shirt, black gloves, a choker around his neck, a necklace, a red armband, and a belt.

Personality

Luka possesses an upbeat, warm, and highly passionate demeanor. Having experienced personal hardship in his past, he is motivated by a strong desire to instill hope in others. He is exceptionally diligent, believing in training hard while others are resting. To the children of the Underworld, he acts as an encouraging role model and protective older brother figure. For Luka, the true value of fighting lies not merely in winning, but in overcoming fear and giving his absolute all in every punch.

Abilities

Luka is a Physical-attribute character walking the Path of Nihility, relying on mixed martial arts and boxing techniques. His basic attack, Direct Punch, deals single-target Physical damage, while consuming stacks of Fighting Spirit allows him to execute an enhanced attack, Direct Sky-Shattering Punch, unleashing multiple strikes followed by a powerful finish. His skill, Lacerating Fist, inflicts damage and causes the target to bleed, dealing continuous Physical damage based on the target's maximum HP. His Ultimate, Winning Strike, grants Fighting Spirit stacks while delivering heavy damage.

Background

Originally an apprentice blacksmith in Hammerlock Town, Luka was recruited into Wildfire by Oleg roughly six years ago. A year later, he lost his right arm protecting townspeople during a monster attack, adopting a mechanical prosthetic afterward. He went on to become a multi-time champion at the Boulder Town Fight Club and an action advisor for The Moles. He later honored the memory of a deceased young fan by fulfilling her final wishes. Selected to represent Jarilo-VI at the Luminary Wardance on the Xianzhou Luofu, Luka faced formidable opponents, overcame severe self-doubt, and ultimately helped establish a trade agreement between Belobog and the Xianzhou Luofu.

Relationships

Luka respects Oleg as his master and works alongside Natasha and Seele to protect the Underworld. Within The Moles, he is a beloved advisor and older brother figure to Hook and the local children. He shares a close bond of mutual trust with the Trailblazer, who supports him through his training and competitions. He maintains a respectful relationship with Svarog and Clara, with Clara providing him a spare prosthetic arm. During his time on the Xianzhou Luofu, he also built memorable connections with fighters such as Yanqing, Boothill, and Topaz.

Trivia

Due to his vibrant red hair and energetic personality, fans frequently draw humorous comparisons between Luka and Diluc from Genshin Impact, another title by the same developer. Additionally, his prosthetic right arm undergoes multiple modifications throughout his story, ranging from standard mechanical models to advanced Interastral Peace Corporation exoskeletons.
