Laura was a Human assimilated by the Borg at Wolf 359.
As a Borg drone she was capable of existing in Unimatrix Zero during her regeneration cycles. This was due to a recessive gene mutation that allowed her to experience individuality in Unimatrix Zero while regenerating. Within Unimatrix Zero, she was friends with Seven of Nine and Siral.
When Seven of Nine returned to Unimatrix Zero in 2377 for the first time in several years, Laura told her that she looked out of place there with her cybernetic implants. It was also during Seven's arrival that Laura chided Korok, after he warned that Seven was putting them and her ship at risk by being there, by asking him he shouldn't be off sharpening his teeth.
As Seven's interactions with Unimatrix Zero went on, Laura participated in a plan where she and the rest of the drones in Unimatrix Zero would retain their memories and individuality while awake as drones. She was a part of the Borg resistance movement against the collective. When the Borg Queen sent drones to Unimatrix Zero to end the resistance, Laura noted, at one point, that there were eleven drones nearby, within three hundred meters. Later when it was learned that they would be able to retain their individuality after completing their regeneration, whereby they could continue their resistance, Laura pointed out that their ships were "scattered across the galaxy", and that it was likely that they would be "the only drone on board who knows about this place."

Later, when it was agreed that Unimatrix Zero be destroyed, she asked Axum, "will there be anything left?" (VOY: "Unimatrix Zero, Part II")
