Locutus of Borg

In a parallel universe, Locutus of Borg was the identity which was forced upon Jean-Luc Picard when he was assimilated by the Borg.

Biography
The Borg intended to use Picard to facilitate the surrender of the United Federation of Planets. Standing aboard a Borg cube, Locutus oversaw the battle against Starfleet at Wolf 359, a fixed point in time which saw the deaths of 11,000 Starfleet personnel. During the battle, Locutus came face to face with the Eleventh Doctor who, accompanied by Amy Pond and Rory Williams, had travelled back in the TARDIS to acquire the Borg Collective's executive routines for their future conflict with the Cybermen. However, due to the nature of the Collective, Locutus saw them as insignificant and so took no action before they promptly left.

Ultimately, Picard was rescued by the crew of the USS Enterprise-D before the Borg cube was destroyed, defeating the Borg invasion. Though Picard was freed from the Borg Collective with the assistance of Data, the Borg continued to refer to him by the name Locutus. (COMIC: Assimilation²)
