Rockwing

Rockwing is a brilliant silver appaloosa stallion with dark blue and gray feathers, one white front anklet, and a black mane and tail highlighted with white.

Personality
Rockwing is evil, and dark hearted, evidenced in Starfire, when he tries to force Star to make a pact with him. He also had no qualms murdering Grasswing's colt, Graythorn, when his captains kidnapped him. Throughout the series, Rockwing displays psychopathic behaviour and his greed for power ultimately got him killed in the end.

Trivia

 * All of his colts are stillborn. He passed this curse on to one of his two surviving fillies, Petalcloud. It is unknown if Shadepebble inherited this, as she doesn't have any foals.
 * He does have two surviving fillies, known as Petalcloud and Shadepebble.
 * His mate was Birchcloud, who later joined the United Army.
