Castiel

An esteemed and powerful warrior angel of Heaven, Castiel has strong morals and a deep hatred for all things evil and demonic. Unlike most other angels, Castiel has free will, and is able to choose his own path, allowing him to make decisions and choose his own moral stance on issues. Though still genuinely good and kind, he is able to break certain rules other angels can't or wouldn't, such as going against or disregarding holy commands. Castiel has a kind but generally dry personality, unshakeable loyalty to his friends, and he is still learning about humanity through those who meets. Cas doesn't exactly understand humor, though he does try. His tone and word choice tend to be flat, matter-of-fact, and succinct. His expression, as well, is generally calm and serious, and his stereotypical business attire and ever-present tan overcoat further accentuate the appearance of a plain, nondescript everyman. From the TV show Supernatural.
