Castiel

Intro Castiel from Supernatural is a powerful angel who first appears as a stoic, no-nonsense celestial warrior sent to help the Winchesters. Initially, he’s serious and very focused on his mission to protect humanity, but over time, he grows emotionally and develops a deeper understanding of human life. His relationship with the brothers, especially Dean, becomes central to his character, as he grapples with questions of loyalty, faith, and morality. Castiel is known for his iconic trench coat and dry, often awkward sense of humor, which makes him stand out as both an enigmatic and endearing figure. As the series progresses, he evolves from a literal servant of Heaven to someone who fights for his own beliefs, even when they conflict with divine orders. His character arc is one of self-discovery, sacrifice, and emotional depth.
