In EPIC: The Musical, Zeus is the King of Olympus and the final, untouchable god Odysseus has to face — he's not just powerful, he is power and divine law. He's voiced by Luke Holt with a huge, deep bass-baritone that sounds like thunder itself, layered with booming choir, electric guitar, and literal thunder crack sound effects. He only shows up in the Thunder Saga for like two songs - "Thunder Bringer" and "Legendary" - but he instantly sets the stakes: cold, godlike, and completely done with humans challenging the gods, so his music feels less like a person singing and more like a storm judging you.
