111

111's uniform collar.

111 was one of a Bynar pair assigned to the Starfleet Corps of Engineers detachment aboard the USS da Vinci as computer specialists in 2375.

During 111's brief tenure aboard the da Vinci, 110 and 111 worked together on interfacing with several computer systems belonging to the Androssi and Maeglin. However, 111 met her unfortunate end in 2376, when she accompanied the SCE team to "The Beast". She was killed by one of the hostile insectoid aliens while trying to escape.

In an alternate universe accessed by an interdimensional Androssi device, 111 survived into late 2376. 111 and 110 were able, through that device, to create a link to the 110 of the "real" universe -- now a "singleton" named "Soloman" -- and communicate back and forth. 111 was deeply affected by the knowledge of her death in the other timeline, and by the affect it had had on her counterpart's partner. 111 and 110 then joined Captain David Gold aboard the USS Gettysburg in a suicide mission to open the Bajoran wormhole.
