Background / History

After the fall of Kronos, Poseidon sought the throne of the King of Gods. Zeus secured the position instead, leaving Poseidon disbelieving and resentful. In the subsequent division of realms, Poseidon drew dominion over the sea, a domain that greatly strengthened his laws and divine power. 42

Unwilling to accept Zeus's rule, Poseidon repeatedly sought opportunities to overthrow him. He attempted to recruit Athena, then incited Atlas to attack Olympus while Zeus slept. Later, he joined Hera, Athena, and Ares in a coordinated rebellion, using the ocean's authority to suppress Zeus's sky authority. 54 99

The coup failed. Zeus stripped Poseidon of his divine power and exiled him to the mortal world for redemption, assigning Apollo to supervise him without directly assisting him. 107

While cursed, Poseidon attempted to earn release by rebuilding a ruined city-state, but his work initially failed to satisfy the curse's conditions. He later remained near Mount Troy to protect and help raise Dardanus, anonymously laboring as the “Cloaked Giant” and constructing the future city with immense physical strength. This experience taught him the value of mortal faith, which he saw as a means to grow strong enough to challenge Zeus. 110 111 132 134

After regaining his position as sea god, Poseidon supported Phineus's attempted coup in Ethiopia through his messenger Thalassa and divine artifacts. When Perseus killed Phineus and petrified Thalassa, Poseidon retaliated with tsunamis and sea monsters, bringing him into direct conflict with Athena and Theron. 162 164

Appearance

Poseidon is a towering, powerfully built god whose presence carries the oppressive force of the sea. He is commonly depicted wielding a golden trident, with waves and foam surrounding him when he manifests from the ocean. 164 172

• Thick curls likened to ocean waves and a heavy blue beard 164 172
• Deep-sea-blue eyes, often described as blazing with fury 172
• Broad, muscular bare upper body in battle 164
• Deep-blue robes or a sea-blue robe in formal settings 100 277
• Golden crown and golden trident 243
• Travels in a golden chariot drawn by four hippocampi 96 172
• During his exile, wore tattered linen clothes, went barefoot, and became covered in dust and mud 110

Personality

Poseidon is proud, impulsive, and intensely sensitive to humiliation. He considers himself entitled to respect as one of Olympus's strongest gods and reacts violently when mortals or gods reject his authority. His loss to Athena in Cecrops City's patron vote and later defeats by Theron became lasting sources of rage. 174 217 280

His ambition centers on surpassing Zeus. Poseidon believes that expanding the sea over land would grant him enough authority to rival the sky, and he repeatedly attempts to exploit discord within Olympus to seize the divine throne. 54 134 217

Despite his arrogance, Poseidon can be practical when forced into a disadvantage. During his mortal punishment, he sought Theron's help to understand the terms of his curse and protected Dardanus while awaiting the city's construction. He also eventually recognized Theron's overwhelming power, developing genuine fear after their confrontation. 111 132 273
