History
Kugo spent most of her young adulthood as other species. At least 9 times before her final assassination attempt, Kugo underwent a genetic medical procedure to alter her appearance and gene structure to reflect that of the species needed to murder her target. Kugo worked as an assassin for two Romulans, a Lasha and Tey; who gave her her missions. During her twenty years as a Romulan assassin, Kugo had been at least a Klingon, a Bolian, a Human, and a Cardassian. To her knowledge, she was of Romulan origins.

On June 14th, 2373, Kugo successfully murdered Willy T. Cutledge: a human politician with xenophobic views. During this assassination, Kugo was altered from her previous state to a Vulcan. Desiring to leave the world of being an assassin, Kugo escaped and created a life within Starfleet. Not long after, she joined the USS Phoenix-X. (PNX: "Identity")
