Lansor

Lansor as a Borg drone in 2368.

Lansor aboard Voyager in 2376.

Lansor was a member of Seven of Nine's unimatrix and a former Borg drone designated as Two of Nine, Primary Adjunct of Unimatrix Zero One.

In 2368, a Borg sphere crashed on Planet 1865-Alpha, an uninhabited planet in the Delta Quadrant. The drones Two of Nine, Three of Nine (real name Marika Wilkarah), Four of Nine (real name P'Chan), and Seven of Nine, were the only survivors. Their link to the Borg Collective was temporarily severed, allowing them to regain their individualities. Lansor recalled working in mathematics before his life as a drone. P'Chan, Lansor and Wilkarah intended to hide so that they would not be found when the Borg came to retrieve them. They went their separate ways. However Seven of Nine, terrified of her newfound aloneness, hunted each of them down and forcibly interfaced with each of them using her assimilation tubules. She caused the left parietal lobes of their brains to be transformed into interlink nodes that linked them together in an ad-hoc collective, then erased the act from their memories. She then led them back to the crash site, where the Borg retrieved them.

Eventually, P'Chan, Lansor and Wilkarah escaped the Collective, but could not break their ad-hoc link, and thus were denied true individuality. In 2376 they sought out Seven of Nine on Voyager in the hopes that she could help them, and discovered her responsibility for the link.

The Doctor, Voyager's holographic Chief Medical Officer, found that the only way to break the link was to remove the interlink nodes. However, this would kill them within a month. They agreed, preferring even a short life as individuals to being linked together. Lansor decided to spend his remaining time at the Markonian outpost at which Voyager had been docked.

Lansor was played by Trek veteran Vaughn Armstrong.
