The Romulan officer who oversaw the brainwashing of the captured Geordi La Forge.
Taibak is a Romulan officer who directs the programming of Geordi La Forge after the engineer is captured on his way to Risa. Taibak exploits La Forge's VISOR to reach his visual cortex, implanting commands and false memories so that La Forge returns to the Enterprise unaware.
In The Mind's Eye, Taibak's work is part of a Romulan plan to drive the Klingons and the Federation apart by making it appear that Starfleet is arming rebels on Krios. His conditioning nearly leads La Forge to assassinate the Klingon governor Vagh.
