Taneko was a Bolian Starfleet officer in the early 24th century, best remembered for leading the Federation fleet at The Battle of Alphard. In the late 2340s and early 2350s the Tholians had been testing the waters with their borders to the Federation, attacking some Federation outposts to see how the Federation would respond. The Federation sent a fleet, under the command of Admiral Taneko and his flagship, the USS Mizar, to stop them, leading to the Battle of Alphard in 2351.
