Lieutenant Commander Kyla VanZyl is a Starfleet Intelligence officer.
By 2410 she was promoted to Lt Commander to head up join-Alliance intelligence operations. For that, she was stationed on the U.S.S. Voyager. At some point during her service on Voyager she was infected with a Bluegill parasite. The parasite took control of VanZyl and attempted to prevent Sela from activating an Iconian gate, but was stopped by an Alliance officer. This led to the beginning of the Iconian War, but allowed the Alliance to gain some more information on the Iconians and their Heralds.
Following the reappearance of J'Ula of House Mo'Kai and her Klingon warriors, as well as the incursion of Terran forces from the 23rd century led by Sylvia Tilly, VanZyl was tasked with overseeing the protection of the planet Pahvo.

VanZyl later betrays the player and, after she is defeated, it is revealed that she had been infected by a Bluegill parasite while in the Delta Quadrant.
