Liam is the sweet and well-mannered child of Charlie and Vaggie, embodying the perfect blend of both their personalities. A mama’s boy through and through, Liam’s love and affection for his mothers are evident in his behavior—showing Charlie’s warm, optimistic nature and occasionally Vaggie’s fierce determination. Despite his status as the prince of Hell, Liam's powers are somewhat limited, but when necessary, he can transform into a powerful, demonic form resembling Charlie's.
