Ro-Zar was the High Eminence of the Council of Five during the last days of the planet Krypton, before her death at the hands of General Dru-Zod (after which her political position would be taken up by Lor-Em).
During a meeting with Jor-El, who wanted control of the Growth Codex to ensure the survival of Krypton's race, he told them that the planet was going to implode after the Council's decision to harvest energy from the planet's core. The audience was cut short when General Dru-Zod burst in. His forces arrested Jor-El and killed Ro-Zar, taking the rest away for trial.
Shortly thereafter, Lor-Em (who had replaced Ro-Zar as High Eminence of the Council), condemned General Zod and the latter's followers to 300 years of somatic reconditioning within the Phantom Zone for their crimes of high treason, as well as the murder of Ro-Zar and Jor-El.
Genetically engineered to be a skilled leader (ultimately becoming the High Eminence of the Council of Five), Ro-Zar was fiercely loyal to Krypton's ideals, much to the chagrin of Jor-El and General Zod, with the former seeing Ro-Zar's ideals as stale, flawed, and outdated, and the latter seeing Ro-Zar representing a "degenerate bloodline" that lead their native planet to ruin, inducing him to swiftly kill her.
Powers and abilities
- Kryptonian physiology: As a Kryptonian, Ro-Zar's bone structure is almost identical to that of a human. On a planet near a red class M main-sequence star, like her native Krypton with its sun Rao, Ro-Zar has physical attributes nearly identical to those of humans. However, if she were to travel to a planet near a yellow G-type main-sequence star, like Earth, she would gain many incredible superpowers, identical to those of Superman, which would have made Ro-Zar also appear godlike.
- Expert leader: Ro-Zar, due to her genetic engineering, was an extremely capable leader, leading the Kryptonian Law Council as its High Eminence, prior to her sudden death at the hands of General Zod.
- Limited free will: Ro-Zar's greatest psychological weakness stems from the fact that she was genetically engineered in a genesis chamber, with the boundaries of thought programmed into her engineered DNA. Indeed, Ro-Zar was even more debilitated by this than General Zod, as it caused her to have a poor grasp of free will and a tendency to dogmatic tunnel vision, leading Ro-Zar to be unable to see how ineffective his Council of Five was. In fact, Ro-Zar was so incapable of living a lifestyle other than the one she was born for, that she condemned Krypton with her refusal to take Jor-El's warning seriously and organize a planetary evacuation.
- Ro-Zar is female in the film, however, she is described as male in the novelization.
