Basso Tromac was a Bajoran collaborator who worked for the Cardassians during the occupation of Bajor on Star Trek: Deep Space Nine. Among his duties was recruiting comfort women for Cardassians on Terok Nor. He was portrayed by David Bowe.

In 2346, he chose Kira Meru to be a comfort woman, along with a woman who called herself "Luma Rahl", who was actually Kira Nerys, Meru's daughter who traveled back to the time of the Occupation using the Orb of Time. After the Bajoran women were prepared, Basso instructed them as to what their new duties would entail. Upon realizing that Meru had a scar on the side of her face, Basso attempted to have the woman removed for being "imperfect", but was stopped by Gul Dukat, who healed the scar with a dermal regenerator.

Although Basso attempted to treat the comfort women with contempt, he was often repressed by Dukat. This, however, was only a ruse by Dukat to instill trust and loyalty from the women.
