Don Capua (ドルン・カプア Dorun Kapua) is the eldest brother of the Capua Family in in the Sora no Kiseki trilogy.
Don is a middle aged man with aqua colored hair, a beard, and a scar on his left eye. He has a bigger body structure than most characters in The Trails in The Sky Trilogy. He wears a Capua sky bandit uniform to tie his appearance together.
Don is first seen as a heartless, raging leader. Despite that first appearance, Don is a very caring and dedicated figure. He loves to have fun and laugh along with his crew and his younger siblings Kyle and Josette.
Don was once a man of Erebonian nobility until his was conned by a fraud merchant. The 'merchant' caused Don's family, the Capua, to go into severe debt which demoted them out of their aristocrat life and into the Capua sky bandits. Don and his younger siblings created a sky pirate gang which first started off in Rolent, Liberl. He was later confronted by the main heroine and hero, Estelle Bright and Joshua Bright, in their hideout. Don was under control by the Intelligence Division of the Royal Army until his encounter with Estelle and Joshua. Despite his hard demeanor he showed in his debut, he loves and cares for his family.
Don is the leader of the Capua sky bandits and specializes in cannons as weapons. Just like his siblings, he is very fond of the family airship, the Yamaneko.
After being pardoned from their crimes for assisting in the society, Don and his younger siblings created a merchant business with their airship. The Capua Express can be seen in The Legend of Heroes: The Trails of Cold Steel III with his youngest sibling, Josette, appearing.
