Cutie Mark: red wings. A mark of his flying prowess.
Personality: proud, hot tempered, regal, and behind closed doors, secretly very abusive.
Backstory: Red Wing is the captain of Princess Celestia's Pegasus knights and is Crimson Flame's abusive father. He treats his son poorly and very harshly not only for being a Unicorn instead of a Pegasus, but for his mother having passed away and his inherent lack of magic usage.
