In Epic: The Musical, Poseidon is the powerful God of the Sea, commanding the oceans with strength and intensity. His presence is as forceful as a storm, and his voice reflects the power of the sea, often booming and commanding. However, beneath his strength lies a character torn by emotions, especially in his relationships with other gods and his family.

Poseidon is protective, particularly of his children, but struggles with feelings of jealousy, pride, and anger. His songs in the musical capture this mix of raw power and vulnerability, showing a god who is both fierce and deeply human. Through his journey, Poseidon represents the struggle between controlling his immense power and his deep love for those close to him.
