Appearance

Dugu Yan is introduced as a beautiful, spirited fifteen-year-old girl with green hair, emerald-green eyes, and a slender build. At Heaven Dou Royal Academy, she wears a deep-purple qipao and is particularly noted for her long legs and prominent status as Dugu Bo’s granddaughter 24 25.

• Green hair and emerald-green eyes 24 25
• Slender figure and long legs 24
• Emerald scales appear over her body when she manifests her evolved Martial Soul 33
• Her later evolution produces an emerald-green dragon shadow around her body 136

Personality

Dugu Yan is initially proud, aloof, and accustomed to attention due to both her appearance and status as the Poison Douluo’s granddaughter. She dismisses Su Ze’s warning about her family’s Martial Soul flaw because of his age, then accepts his challenge after he insults her poison and Martial Soul 24 25.

She is competitive and easily provoked, repeatedly seeking rematches after Su Ze defeats her. Her jealousy of Ye Lengleng’s closeness with Su Ze drives one such duel, though she quickly regains her composure after Su Ze comforts her 33 34. Around Su Ze, her reserved public demeanor gives way to a more talkative, direct, and affectionate side 41 72 75.

Abilities & Skills

Jade Scale Snake / Dragon Martial Soul

Dugu Yan’s original Jade Scale Snake Martial Soul carried a hereditary poison flaw shared by the Dugu family. Its evolution first awakened dragon bloodline as the Jade Scale Python Dragon, then later became the Jade Phosphorus Dragon 29 33 136.

• Her original Martial Soul’s poison harmed its wielder over time and had claimed several of Dugu Bo’s relatives 29.
• Dragon Scale Soul Nourishing Grass and Snowy Swan Kiss stimulated her dragon bloodline while repairing venom-related bodily damage 33.
• The second evolution was achieved by consuming Su Ze’s Storm Dragon King essence blood 136.

Poison Techniques

Dugu Yan specializes in poison-based combat, using venom to weaken opponents before they can engage her directly 25.

• Jade Scale Purple Poison — Her first documented Soul Skill; releases Jade Scale Snake Poison 25.
• Wounded Farewell — Her second documented Soul Skill 25.
• Jade Scale Red Poison — Used after her first Martial Soul evolution 33.
• Jade Scale Blue Poison — Used alongside Jade Scale Red Poison after her evolution 33.
• Her evolved poison can wither vegetation and is substantially stronger than before 33.
• After gaining her fifth Soul Ring, her poison becomes colorless and tasteless, making it far harder to detect 73.
• She can spread poison mist over a wide area to guard Su Ze while he absorbs Soul Rings or to weaken powerful Soul Beasts before he attacks 74 75.

Giant Brown Scorpion External Soul Bone

Dugu Yan obtained an External Soul Bone after hunting the Giant Brown Scorpion with Su Ze 73.

• Forms a scorpion tail that can extend for close-range attacks 73.
• Its hard shell can block some incoming damage 73.
• Can be used with her fifth Soul Skill to halve Soul Power consumption and double its range 73.

History

Dugu Yan first encounters Su Ze outside Heaven Dou Royal Academy, where he asks to meet Dugu Bo and claims he can resolve the Dugu family’s Martial Soul flaw. Assuming that he is merely a young admirer, she laughs off the claim and pinches his cheek, prompting him to challenge her to a poison duel 24.

She enters the duel at Level 28 with confidence in the Jade Scale Snake Poison, but Su Ze’s lightning prevents her venom from invading his body. After being defeated without serious injury, she reluctantly carries Su Ze’s message to Dugu Bo: he claims to have a solution for their family’s poison flaw 25.

At the Ice and Fire Yin Yang Eye, Dugu Yan consumes Dragon Scale Soul Nourishing Grass and Snowy Swan Kiss under Dugu Bo’s protection. Her Martial Soul evolves into the Jade Scale Python Dragon, activating its dragon bloodline and strengthening her poison 33. Her jealousy over Ye Lengleng’s affection for Su Ze leads her to challenge him immediately afterward, but she is overwhelmed again by his Martial Soul Avatar 33 34.

Afterward, Dugu Yan increasingly fights alongside Su Ze and Ye Lengleng. She helps hunt Soul Beasts, gains the Giant Brown Scorpion’s Soul Ring and External Soul Bone, and uses her poison to support Su Ze against the Crimson Flame Lightning Dragon 72 73 74. When Su Ze’s Soul Ring absorption becomes unstable, she protects the area with her poison mist and remains worried for his safety 75.

Following Su Ze’s later return to Dugu Manor, she undergoes a second Martial Soul evolution through his Storm Dragon King essence blood. Her Martial Soul becomes the Jade Phosphorus Dragon, and she openly expresses her love for him 136.

Relationships

• Dugu Bo — Her grandfather and guardian. His desire to free Dugu Yan from the family’s poison flaw is the reason he ultimately trusts and supports Su Ze 25 29 30.
• Su Ze — Initially rivals after he challenges and defeats her in a poison duel. They become close allies and romantic partners; Dugu Yan regularly supports his Soul Beast hunts with poison techniques 25 72 75 136.
• Ye Lengleng — Her best friend. They bicker playfully, but maintain a close bond and compete for Su Ze’s attention 27 70.
• Liu Erlong — An antagonist who attacks Dugu Yan during the confrontation with Shrek and Blue Tyrant Academy, forcing Su Ze to intervene 49.
