Leslie Banks was a female Human Starfleet crewperson in the 2370s. In early 2377, she was assigned to the security team of the USS da Vinci, replacing resigning crew member T'Mandra. During her time on the da Vinci, she shared quarters with Ellec Krotine, and the two had become good friends during Banks's first three months aboard.

Despite the best efforts of Dr. Elizabeth Lense, Banks died of her injuries. (CoE eBook: Turn the Page)
