Primary Goal: To create a "hok'taur," a genetically superior human host with latent psychic abilities (telepathy/telekinesis) to serve as her new body, which drove her horrific experiments.

Methods: Used advanced viral agents, genetic modification, and covert labs to modify human populations, such as on Hanka.

Ruthless Tactics: Wiped out the population of Hanka with a retrovirus to hide her work and planted a naquadah bomb in the survivor, Cassandra, to destroy Earth's Stargate.

Political Maneuvering: A renegade System Lord who used deceit, like faking an emissary to destroy an enemy's Stargate, and tried to sabotage the Protected Planets Treaty by attacking Cronus.

Technology: Utilized phase-shifting (invisibility) and advanced healing/experimentation devices.
