"Katherine" clone in over 400 years. Una was one of Trevor's most successful experiments; part of a group of clones that proved to be fertile, with Una having been pregnant when she was killed. However, in order to keep the dynasty of Goodchild clones in power, Trevor's brother, Oren, had Una killed along with the other members of the fertile experimental group. He ordered all of Trevor's research to be destroyed. In a confrontation with Trevor and Æon, Oren reveals that nature has corrected the infertility problem and that some women are becoming pregnant without intervention by scientists. Oren has had them all killed to maintain the Goodchild reign. Æon then goes against both Oren and her former allies, who want to kill Trevor and also kill her for not killing Trevor. Æon convinces the other Monicans tracking her, including her friend Sithandra, to ignore the Handler and to help her kill Oren and his men.

She discovers that he preserved Katherine's DNA for years, although an earlier Oren clone had ordered it to be destroyed so "Katherine" could not influence any Trevors. The dirigible crashes into the city wall, breaking it down to reveal the surrounding land for the first time in centuries.

The producers rejected the idea because Brasília lacked the infrastructure and technical expertise to support a major film production. After several cities were scouted, Berlin and Potsdam in Germany were chosen for filming. Berlin had several locations that fit into the organic yet structured world of Æon Flux. The crew gained permission to film in several locations that had never allowed such access before, including the Treptow Crematorium, the Adlershof Trudelturm and Windkanal wind tunnel facility, and the Haus der Kulturen der Welt ("House of the
