Background / History

Bai Chen died suddenly in his original world after talking with Luo Hui. An unidentified voice revived him and asked him to help “everyone” in the future. He awakened in a ruined city dated March 2014, physically reverted to his fourteen-year-old self and separated from his family. 1

He encountered Kiana, Mei, and Bronya during a Honkai attack. Though Kiana initially saved him, Bai Chen activated his mysterious power when a Temple-class Honkai Beast threatened the group, transformed, and defeated it. He immediately recognized that his newfound strength could destroy the city if misused. 1

Himeko later established that his local identity listed him as an orphan from Chuancheng City, Shenzhou, and arranged his admission to St. Freya Academy. His combat performance was strong, but unfamiliarity with this world’s history, physics, and chemistry caused him to fail the written examinations. 3

His early use of overwhelming powers repeatedly damaged him. Heavenly Fire left him grievously burned, concentrated Honkai energy killed and reconstructed him countless times, and his damaged spirit later caused amnesia and instability when using Herrscher-level transformations. 6 9 14 16

Appearance

Bai Chen normally has the body of a fourteen-year-old boy, though his physical state changes as he develops his powers. Following his Honkai-resistance training, his appearance develops altered skin tone and flame-like streaks in his hair. 9

• In his empowered adult state, he has waist-length silver-white hair with additional purple-pink flame-like strands. 74
• His eyes are purple-pink gradients marked by golden, Divine Ring-like patterns in his adult form. 74
• Myriad Armors covers him in silver-white armor with gold patterns, a multicolored chest core, starlight effects, and a crown-like headpiece. 74
• His appearance, gender, weapons, mannerisms, and even inherited memories can change with each transformation. 2 26 83

Personality

Bai Chen is compassionate and impulsively self-sacrificing. He intervenes when others are endangered, endures severe injuries to protect people, saves Wendy rather than abandoning her after defeating her, and is willing to risk himself to protect entire worlds. 1 6 59 74

He is also mischievous, unserious, and prone to reckless decisions. He teases friends, bluffs strangers, uses disguises freely, and often acts before considering the social consequences. His behavior can unsettle even allies who know that he is fundamentally protective of others. 29 30 76 89

Despite possessing memories from another world and increasingly godlike powers, Bai Chen recognizes his own weaknesses. He trains persistently in academics, martial arts, swordsmanship, and Honkai-energy control, while acknowledging that his untransformed combat experience initially lags behind skilled fighters such as Fu Hua and Yae Sakura. 3 4 8 10 14 26

Abilities & Skills

Possession and Transformations

Bai Chen’s central ability allows him to access other characters’ powers through cards.

• Can borrow a specific skill or weapon while remaining in his own body. 2
• Can transform into another character, stacking that character’s physical condition and abilities onto his own. 2
• Transformed states are limited to the original character’s powers and Bai Chen’s own knowledge. 2
• Powerful forms can impose cooldowns measured in years, though his growth and Elysian Realm rewards reduce these restrictions. 2 55
• Powerful transformations can influence his personality through inherited memories and emotions, particularly while his spirit is damaged. 15 16
• He can unlock forms by integrating a target’s soul or data, or by causing their emotions toward him to reach an extreme. 34

Honkai Energy Adaptation

Bai Chen survived repeated destruction in a high-Honkai-energy environment and emerged with improved resistance and control.

• Possesses Advanced Honkai Energy Manipulation and Advanced Honkai Resistance. 9
• Can endure and recover from damage that would normally be fatal, including being reduced to ash. 9 50
• His recovery is not without cost: extreme power use has caused coma, amnesia, spiritual damage, and physical exhaustion. 6 14 16

Dimensional Walls and Spatial Authority

Bai Chen can move people and objects through dimensional pathways.

• Retrieves distant objects, including the Xuanyuan Sword, with spatial authority. 25
• Teleports the Blade of the Immortals directly to Schicksal headquarters. 59
• Uses Dimensional Walls for travel between worlds and locations. 54 106
• Can create clones, though operating many simultaneously strains him. 68 118
• Clone bodies cannot access his ultimate Myriad Armament form. 136

Construction, Repair, and Restoration

Through Herrscher of Reason-based powers and compatible Stigmata, Bai Chen can create and repair complex structures.

• Constructs living bodies from blood, though a created body initially lacks a soul. 68
• Transfers stored information and consciousness into a prepared body, as demonstrated in Kallen’s revival. 70
• Repairs damaged automaton soldiers and restores Svarog to near-factory condition. 86 93
• Forges replacement weapons that closely replicate the originals, though they do not retain the originals’ attribute bonuses. 105
• Large-scale mechanical repair significantly weakens him. 86

Martial Arts and Swordsmanship

Bai Chen supplements his transformations with personally trained combat ability.

• Trained under Fu Hua, Yae Sakura, NPC A, and Jia. 10 14 25 26
• Learns through repeated death in training spaces, allowing him to test dangerous techniques without permanent death. 26
• Can wield katana-based abilities through Phantom Drive · Kageyoshi. 14
• Later teaches basic swordsmanship to Jingliu and uses advanced Drives to support his technique. 133 134

Myriad Armors

Bai Chen’s ultimate armored form combines his accumulated Authorities and special powers.

• Its armor resists attacks unless an opponent can match the scale and number of Authorities embedded within it. 93
• Switch: Burst separates the armor into autonomous components that attack multiple enemies. 74
• Grants an adult body, flight, immense physical force, and a Divine Ring-like manifestation. 74 93
• Can be used alongside other Stigmata, though excessive combinations inflict severe self-damage. 74

Water Dragon and Cloud Chant

While using the Yin Yue identity, Bai Chen demonstrates powerful water- and mist-based techniques.

• Summons the Water Dragon to block attacks, restrain enemies, and defeat Blade. 115
• Creates cloud-and-mist illusions and teaches Bai Lu to manipulate them through the Cloud Chant Technique. 116
• Bai Lu displays rapid aptitude under his direct instruction. 116

Equipment / Weapons / Items

• Card system and wrist bracer — cards serve as the focus for his transformations; the bracer itself is a decorative shell. 3
• Heavenly Fire — dual pistols that combine into a flaming greatsword; exceptionally destructive but dangerous to Bai Chen’s body. 6
• Phantom Drive · Kageyoshi — black-and-red katana-based armament. 14
• Xuanyuan Sword — retrieved through his spatial authority and given to Himeko. 25
• Cleansing Seven Thunders — Divine Key used to disintegrate Honkai energy crystals. 23

• Fu Hua — Guides Bai Chen’s Honkai-energy control, trains his original body, and helps conceal knowledge of his transformation ability. 9 10
• Kallen Kaslana — Her data becomes part of Bai Chen, enabling her to manifest and control his transformed body; Bai Chen later restores her to an independent body. 6 70
• Yae Sakura — Swordsmanship mentor and caretaker who becomes more comfortable with Bai Chen after he saves Kallen. 14 16
• Elysia — Helps Bai Chen enter the Elysian Realm trial and welcomes his growth after his battle with Chijie. 55 56
