Kova Tholl was a Mizarian public servant who enjoyed private meditation and was considered one of the brightest of his race.

He was a pacifist who knew of no one who could bear malice against his race or himself personally. He boasted of his intelligence and considered himself to be neither important enough to be held for ransom nor radical enough to be considered a threat.

In 2366, he was abducted, along with Captain Jean-Luc Picard, Esoqq and Mitena Haro, by a hitherto unknown species for use in a covert experiment to study their different attitudes towards authority. (TNG: "Allegiance")
