Seven of Nine (Star Trek: Voyager)

"What if we made the Borg, you know, sexier?" All the rubber hoses and latex apparel in the Delta Quadrant were no match for Jeri Ryan's Seven of Nine, an assimilated human rescued up by the Voyager crew at the start of season four. Seven's character arc was ostensibly about reacclimating to independent life after her experiences in the Borg collective, but her skintight catsuit was also a key concern. Her presence managed to weave one of Star Trek's most nefarious enemies into a show that often seemed disconnected from the rest of its universe, and Ryan recently reprised the character, with some significant changes, on Picard.
