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, 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.
