William Sutherland (ウィリアム・サザーランド) is a fictional character from Mobile Suit Gundam SEED.
Once the Archangel finally makes it to JOSH-A, in a meeting with other top Alliance officers, he comments on how Kira Yamato was the one who protected the Archangel prior to his MIA status, in which another officer says it was a "fortunate loss". He also says that the GAT mobile suits are to be relied on in the future, such as the Raider, Calamity, Forbidden, and the Strike Daggers. After Blue Cosmos finds out about ZAFT's planned attack on the base(the information having been provided by Rau Le Creuset), Azrael has Sutherland and the general staff set a trap that would turn the tide of the war in their favor and tip the balance of the Alliance's power towards the Blue Cosmos controlled Atlantic Federation. During the Battle of JOSH-A, Sutherland and the entire Atlantic Federation staff quietly evacuate JOSH-A by submarine, leaving behind the Archangel and the Eurasian Federation forces to keep ZAFT occupied until they were safely away. Once ZAFT breached the base and got deep enough inside, Sutherland and the general staff activated the CYCLOPS system, wiping out 80% of the ZAFT forces, along with their Eurasian allies.
In the Second Battle of Jachin Due, Sutherland as an Admiral commands a Agamemnon-class ship, the Doolittle, which is equipped with TS-MA2 Moebius mobile armors armed with nuclear missiles. He later dies when his ship is destroyed when the Duel, piloted by Yzak Joule, fires a grenade launcher from his rifle, blowing up the bridge.
- He is the Cosmic Era equivalent of Bask Om, as both served as a second in command to the supreme leader of their respective Terran radical groups.
- In fact, the meeting in JOSH-A, especially the exchange between him and Murrue Ramius, could be loosely based off of Bright Noa's meeting with the Bask Om of the Titans in Mobile Suit Zeta Gundam(Bright with Bask and Murrue with William), both were between the ship captain and the radical sector's second in command, and their exchange has some disagreement. However, what happened to the respective series' captains were different: Bright Noa gets physically beaten up by the Titans officers, whereas Murrue Ramius' life was almost sacrificed by Blue Cosmos in the Cyclops explosion. Both captains defect after these incidents in their respective series.
