From Macross Compendium
Boy who was burnt out by a certain planetary civil war. He is a strong mechanic who drifted to the Frontier Fleet after repeatedly stowing away on spaceships. Since meeting Hakuna Aoba and Chelsea Scarlett on Island Reno, he rolled into the Robbins Family, becoming an apprentice mechanic. Originally, he liked mechanical tinkering and Chief Katori recognized his genius as a mechanic. Through his circumstances, he fears and hates war, but to break his dilemma, he aims toward the goal of a soldier. He is a so-called "Peace-Child", being a mix of Zentradi and human. Although he has a younger sister, he parted with his family due to the planetary civil war.
