Torsus

From Memory Alpha, the free Star Trek reference.

Torsus was part of the group of rogue Borg led by Lore.

In 2369, it was part of the team which attacked the Federation outpost on Ohniaka III. When an away team from the USS Enterprise-D arrived, Torsus group fought against the away team. In the battle Torsus was killed by Commander Riker, for which another Borg swore revenge. (TNG: "Descent")

Torsus was played by an unknown stuntwoman.
