Donald Hayes was the father of Lisa Hayes and an Admiral on Earth before the Zentraedi destruction.


Donald Hayes served in the American Navy during the Global War. After Zor's Battlefortress crashed on Macross Island, he joined the newly formed UEG. After the Zentraedi attacked Earth and began the First Robotech War, the SDF-1 folded away, and Donald Hayes declared that the SDF-1 and Macross City had been destroyed by Anti-Unification League terrorists. When the SDF-1 returned, he demanded they leave and draw the attention of the aliens. This made his one-time friend, Henry Gloval, a bitter enemy. (Macross Saga: Boobytrap, Homecoming)

Instead of using negotiation, Donald Hayes believed that the experimental Grand Cannon was the best way to end the war. He was convinced that the Grand Cannon would be able to wipe out a Zentraedi invasion force. While it did destroy a portion of the fleet, Dolza had five-million ships and he easily shrugged off those losses. He did, however, now know where to look for the weapon. His men destroyed it and then killed Hayes. His last words were to his daughter, telling her that she was right about everything, and saying he was sorry for not believing her.
