Background

Poseinan is a transmigrator born in the God Realm to Poseidon, the first-generation Sea God, and the Goddess of Love. Though raised with exceptional status and care, he worries that Tang San will eventually inherit his father's god position and jeopardize his own future. After failing to obtain the Asura God's favor, he chooses to prove himself in the mortal realm instead. 1

In the God Realm, Poseinan was known for visiting goddesses and charming them with his words. After threatening to abduct the God of Destruction's hypothetical future daughter, he earned the nickname “Demon Child.” 1 Hela, the Goddess of Death, later secretly places a Death Scythe mark on the back of his neck and gives him a primordial embryo intended to develop into a second Martial Soul. 2 12

At the God Realm celebration, he volunteers for lower-realm training. The God of Destruction accepts his request, injects a wisp of destruction divine power into him, and sends him to Douluo Planet without placing him directly on Sea God Island. 3

Appearance

Poseinan is introduced as a young blue-haired boy with cream-colored skin, an adorable face, and deep blue eyes. His Sea God lineage becomes especially apparent when he manifests his Martial Soul. 1 10

• Blue hair and blue eyes. 1 5
• Carries a dark-purple Death Scythe pattern on the back of his neck. 2
• Manifests a Sea God phantom in a blue robe, with a trident-shaped crown and the Sea God Trident. 10
• After refining whale glue, his skin gains a warm, jade-like luster. 13

Personality

Poseinan is ambitious, calculating, and unwilling to rely solely on his divine birth. He descends to the lower realm specifically to establish his own path, declaring that he will not regret the journey even if it kills him. 3 He pursues extreme cultivation standards rather than accepting ordinary limits, beginning with a 3,000-year first Soul Ring. 12 13

He is also mischievous and sharp-tongued, freely provoking figures such as the God of Destruction, Bibi Dong, and his own father. 1 8 11 Despite this, he is empathetic toward children suffering under family neglect, particularly Qian Renxue, and risks Bibi Dong's wrath to defend her. 5 9

His combat approach favors patience, deception, and exploiting the opponent's assumptions. Rather than confronting Xiaobai directly, he repeatedly uses Elementalization to seed his domain across the battlefield before revealing the full trap. 15
