Doctor Ozaba was a Federation scientist stationed on Minara II to study Minara's development into a nova in 2268. He was familiar enough with the Bible to quote Psalm 95:4 to his associate, Dr. Linke, when the latter referred to the planet as a "Godforsaken place".
Ozaba and Linke were kidnapped and tortured by the Vians, who eventually killed the two scientists. The Vians' actions were an attempt to teach the empath Gem, a Minaran inhabitant, to comprehend compassion and self-sacrifice in effort to determine if her planet's inhabitants were worthy of saving from the sun's impending nova.
