Torrot

From Memory Alpha, the free Star Trek reference

DaiMon Torrot was a Ferengi assimilated by the Borg. In 2375, when the USS Voyager encountered a Borg vinculum infected by Species 6339's synthetic pathogen, Seven of Nine began to experience the personalities of various assimilated individuals, including DaiMon Torrot.

Seven, as Torrot, claimed that "he" had been having a nagging pain in "his" lower left lobe, and suggested that Voyager's EMH run a complete tricardial diagnostic on "him" because the Ferengi Health Commission had been trying to revoke "his" trading license. (VOY: "Infinite Regress")

Torrot was played by actress Jeri Ryan, sort of.
