Haily is a Mobile Suit pilot in the Delaz Fleet and a minor antagonist in Mobile Suit Gundam 0083: Stardust Memory. He is a Zeon soldier who became part of the Zeon remnants after the war ended and one of the pilots who assists Anavel Gato in his theft of the RX-78GP02A Gundam "Physalis".
On 13 October U.C. 0083, Gaily took part of the first stage of the Delaz Fleet's Operation Stardust plan. Alongside Bob and Adamski, Gaily served as part of Anavel Gato's strike team that assaulted the Earth Federation's Torrington Base in Australia with the goal of stealing the nuclear-armed RX-78GP02A Gundam "Physalis".
During the attack, Gaily in his Dom Tropen fought Raban Karcs in the Zaku F2 and defeated it by slicing it in half with his heat saber, killing the pilot. He later destroyed a GM Kai inside the base with Raketen Bazooka rounds. As Gato and the rest of his team escaped with Gundam GP02, Gaily was unable to pursue them and was killed when his mobile suit was fired upon by Federation troops.
