A Zeon resistance leader hiding on the Nazi-ruled planet Ekos in 2268, elder brother of Isak, who tests Kirk and Spock before agreeing to help them.
Abrom appears in the second-season episode Patterns of Force. He leads a cell of Zeons living in a cellar beneath the Ekosian capital, where his brother Isak brings Kirk and Spock after the three escape from prison.
Abrom is angry at the risk. He has just had to tell Isak that his fiancee, Uletta, was shot in the street and left to die. He sees no reason to trust two strangers.
The test comes when Ekosian troopers burst in, led by the party heroine Daras, and Abrom is apparently shot. Kirk and Spock fight to protect the Zeons, the raid is revealed as a sham, and Abrom backs the plan to reach John Gill. He was played by William Wintersole.
