Mobile Suit Gundam
Boone is a Principality of Zeon commander stationed near the Federation's Belfast, Ireland base. When the White Base arrives in Belfast, Boone takes the opportunity to launch an attack on it. During the second such attack, he sends Miharu Ratokie aboard as a spy, to provide information on where it is headed. Boone follows the White Base across the Atlantic Ocean and successfully infiltrates it using a stolen civilian plane so that he can communicate with Miharu, who tells him that White Base is headed to South America, which Boone reports to Char Aznable.
From Char, Boone received gets permission to pilot the MAM-07 Grublo mobile armor in an attack on the White Base, intending to avenge the death of his men that had fallen to the White Base and the RX-78-2 Gundam. Boone launches an attack on White Base and does battle with the Gundam underwater. While the Grublo has the advantage at first and manages to grab the Gundam's leg with one of its claws, the Gundam is able to escape its grasp and then attacks the Grublo's cockpit with one of its beam sabers, killing Boone.
In the second Mobile Suit Gundam compilation movie, Boone was killed by Gunperry's missiles instead.
