Gatrell was a male Klingon in the Klingon Defense Force in the 24th century. In 2376, he was captain of the IKS Sturka, and was one of twelve Qang-class starship commanders assigned to a mission of exploration and conquest of the Kavrot sector.

Gatrell reported finding several habitable worlds in the system Kavrot javmaH jav (Kavrot 66). The natives had no traditional technology, and Gatrell anticipated conquering the system in short order. As such, he did not heed to call to join the battle at Elabrej. However, his first officer, K'Draq, and second officer, Grokla, theorized that the natives had a kind of organic technology, which proved to be so. When the Sturka was forced to retreat, Gatrell blamed Grokla and had him put to death. When K'Draq then challenged Gatrell, the captain refused and had his bodyguards keep any other potential challengers away.

When Gatrell's failures and cowardice were revealed by General Kriz, Gatrell denied it, and refused discommendation. Kriz then killed Gatrell with his disruptor. (KE novel: A Burning House)
