Ma Wang (Cha Seung Won), also known as the Bull Demon King, is a standout character in this supernatural drama. As the CEO of Lucifer Entertainment, his modern-day persona, Woo Hwi, is an entertaining blend of ambition and comedy. Balancing his devilish duties while having a soft spot for his beloved dog adds a surprising layer to his character. His rivalry with Son Oh Gong (Lee Seung Gi) provides much of the show's humor, but Ma Wang’s emotional journey to find redemption is what truly resonates with viewers.

2. Ryu from "When the Devil Calls Your Name"

In this unique drama, Ryu (Park Sung Woong) takes on the role of Mo Tae Kang, a top actor who, in reality, is a devil making deals with humans.

While initially manipulative and charming, Ryu's character becomes increasingly complex, revealing moments of conflict and compassion that blur the line between good and evil, making him one of the most layered devil characters in K-Drama history.

3. Jeong Gu Won from "My Demon"

Jeong Gu Won (Song Kang) is a 200-year-old demon known for preying on human vulnerabilities, luring them into soul-binding contracts.
