Character Arc
Won-seung is the Monkey guardian among the Twelve, portrayed by Seo In-guk. Playful and quick-witted, he brings a lighter, more mischievous energy to the ensemble of immortal protectors, contrasting with the steady gravity of the Tiger guardian Tae-san. As one of the zodiac guardians sworn to defend humanity, Won-seung balances levity with genuine capability in the supernatural battles the team faces.
Like his fellow guardians, Won-seung is drawn back into action when the long-sealed demon O-gwi reawakens and threatens the human world. His arc plays out within the larger story of the Twelve reuniting, recovering their strength, and confronting an ancient enemy. The Monkey guardian's agility and cleverness give the team a distinct asset, and his camaraderie with the others reinforces the found-family bonds at the heart of the series.
Across the single season, Won-seung contributes to the show's blend of zodiac mythology and modern superhero spectacle, with his personality adding warmth and humor to the ensemble's heroics. As a recent release, specific details about Won-seung should be verified against official sources.
