Main Characters and Primary Voice Cast

The series also features complex female leads and morally ambiguous allies, each voiced by a mix of established and rising talent chosen for authenticity and emotional precision.

Mark Grayson, the titular hero, begins as an ordinary teen discovering his powers and maturing into a symbol expected to balance justice with personal cost. Steven Yeun’s performance emphasizes vulnerability, doubt, and resilience, making Mark’s journey a core driver of the series. Over multiple seasons, the writers use Mark to explore themes of legacy, responsibility, and the cost of violence, with Yeun consistently reflecting the character’s incremental growth.
