Julian is one of the many war orphans under the care of the former Zeon pilot Cucuruz Doan on the remote island of Alegranza. Among the group of approximately twenty children whom Doan protects, Julian is distinguished by his red hat, which serves as his most notable visual characteristic. He expresses a childlike wish for a lighthouse as a birthday present, reflecting the central role the island's lighthouse plays in the group's daily life and his own imaginative nature. Julian's background before arriving on the island is not detailed, but it is implied he, like the other children, lost his family due to the violence of the One Year War, which is why Doan has taken on the role of their guardian. In terms of role and personality, Julian is one of the younger members of the island community. The voice actors for the character are Banks Quinney in the English dub and Sōsuke Yoshida in the original Japanese dub. No information is available regarding his specific development, notable abilities, key relationships beyond being one of Doan's charges, or his precise role in the story's events.
