The unctuous captain of the Neimoidian blockade over Naboo, Dofine was an officer in the Trade Federation. Greedy, deceitful and cowardly, Dofine nevertheless had the wherewithal to openly question Darth Sidious' machinations, for which he was verbally reprimanded by the Sith Lord. Despite his insubordination, Dofine remained in command of the blockade's forces. He gave the order to activate the droids on the surface of Naboo. Dofine perished aboard the Droid Control Ship when Naboo starfighter forces destroyed the vessel.
Daultay Dofine was one of the three principal Neimoidian collaborators with Darth Sidious during the invasion of Naboo, working alongside Rune Haako and Nute Gunray.
Dofine was the proud captain of a Trade Federation battleship. During the siege of Naboo, he transferred from a standard blockading vessel to the Droid Control Ship.
It was Daultay Dofine who gave the order to "activate the droids!" from the Droid Control Ship, which awakened the droid army to do battle with the Gungans on the plains of Naboo.
Dofine foolishly doubted Darth Sidious's plan, boldly telling the Sith Lord that his scheme was finished. The Dark Lord ordered Gunray to keep Dofine -- "this stunted slime" -- out of his sight for the remainder of the operation.
Dofine led the month-long blockade of Naboo, which left the fragile planet starved and ill-supplied.
