Shaitani

Shaitani was an individual who was known by a young James T. Kirk to be a great military commander, along with Garth of Izar and Korrd.

While attending Starfleet Academy Command School, Kirk tried to emulate Shaitani during his first attempt of the Kobayashi Maru scenario, but still failed. He later thought of Shaitani when contemplating the nature of the "no-win scenario."
