Yataro

Lieutenant commander Yataro was a male Lirin officer serving in the Federation Starfleet in the mid-23rd century. He was described as an ambitious, excellent problem-solver who was composed and businesslike in all his personal interactions.

History
By the year 2269, Yataro had been assigned to the USS Endeavour (NCC-1895) as chief engineer, replacing Bersh glov Mog, who had died from radiation poisoning when engineering had been breached during the ship's defense of Starbase from a Tholian armada at the Battle of Vanguard the previous year. 

In 2269, after the scout ship USS Sagittarius (NCC-1894) had crashed on Nereus II, Yataro was assigned to assist its crew with repair efforts and later took part in the defense of the ship from an assault by  Tomol. 

When the ship itself participated in the fight after lifting off, two Changed landed on its outer hull and tried to claw their way inside. Yataro, who had stayed on board to assist with last-minute repairs, came up with the idea to electrize the hull to shake them off. 

He later assisted with repairs on the Klingon battlecruiser.
