Locutus
During the Borg invasion of the United Federation of Planets, Picard was kidnapped by the Borg and taken aboard their cube, resulting in Riker taking command of the Enterprise As the crew discovered, Picard had been assimilated into the Borg Collective as his identity was suppressed by Locutus, the emissary of the Borg. After the Borg used Picard's knowledge to easily defeat a Starfleet task force in battle of Wolf 359, Riker devised a plan to turn the tables against the Borg as they proceeded to Earth, entailing the retrieval of the Captain from the Borg cube by Worf and Data. Back aboard the Enterprise, Picard was freed from the Collective as he assisted Data in incapacitating the Borg cube, leading to its self-destruction. (COMIC: Assimilation²)
