WARNING: The following contains spoilers for Star Wars: The Bad Batch Episode 9, "Bounty Lost," streaming now on Disney+.
From the first episode of Star Wars: The Bad Batch, Omega has been unique among the Clones, but the exact nature of her differences was a mystery. Throughout the series and in Star Wars: The Clone Wars, the Kaminoans have been lamenting the loss of Jango Fett because their samples of his DNA have been deteriorating. Now, In Episode 9, "Bounty Lost," Star Wars: The Bad Batch finally confirms why Omega is so valuable to the Kaminoans: like Boba Fett, Omega has first-generation DNA from Jango Fett.
At the beginning of the series, Omega believed she was a "defective" Clone, a label that also was applied to the members of Clone Force 99. Her desire for connection with other people who were different from regular Clones inspired her to introduce herself to the members of the Bad Batch and ultimately led to her accompanying them as they escaped Kamino. However, in Episode 4, "Cornered," Fennec Shand was sent to retrieve Omega, showing that someone, later revealed to be the Kaminoans, specifically had an interest in the girl. Then, in "Reunion," Lama Su, desperate to retrieve Omega, hired Cad Bane, who successfully abducted her on Bracca.
Omega's abduction is terrifying for the team, but it does lead to them finally discovering the truth about her. While searching for clues to try to figure out where Omega is and why she was taken, Tech reveals that he has completed a more thorough genetic analysis and determined the truth of her origins. Tech explains that while most clones' "genetic structure was modified for growth acceleration and obedience, Omega is a pure genetic replication" of Jango Fett. Echo immediately realizes that Omega's DNA makes her vital to the survival of the Kaminoans' cloning projects, which is why they hired bounty hunters to retrieve her.
There have also been hints that Omega was subjected to more experiments than the rest of the Clones throughout the series, with one of the most relevant occurring in the series premiere. After Echo is knocked unconscious in a food fight, he awakens in the medical bay and panics, in part due to his own trauma from the Separatists' experiments on him. In response to Echo's fear, Omega states, "I understand. I don't like being hooked up to their machines, either," implying that she's spent a lot of her life hooked up to machines.
Omega's childhood connects specifically to her realizing the truth of Lama Su's plans for her. In "Bounty Lost," Cad Bane takes Omega to an abandoned Kaminoan facility in the Lido system to exchange her for credits. However, Fennec Shand arrives first and kills Taun We, the Kaminoan's contact. After escaping from Cad Bane, due in part to Fennec Shand's intervention, Omega stumbles upon a chamber filled with tubes, similar to the ones traditional Clones are born in. However, these tubes are filled with the corpses of abandoned experiments. Omega pauses for a moment and sees her own face reflected in the glass before Fennec Shand finds her. And while Omega tries to ask Fennec why the Kaminoans want her, Fennec states that Omega "already knows." Omega then glances back at the tubes, and it's apparent she knows that she will suffer a similar fate if she returns to Kamino.
Omega does eventually escape and return to the team, but she is still terrified of the implications and future attacks by bounty hunters hired by Lama Su. Her fear is also amplified by the physical evidence of what happens to the Kaminoans' experiments once they are no longer useful. After a warm reunion, Omega has a quiet conversation with Hunter, in which she reveals her fear that the Kaminoans will never stop looking for her. Hunter reaffirms that she's not alone and promises to keep her safe. Regardless of his belief, however, the revelation of Omega's true nature heightens the stakes for Clone Force 99 in the second half of the season, while also reaffirming the bonds the team has created with their newest member.
Created by Dave Filoni, Star Wars: The Bad Batch stars Dee Bradley Baker, Michelle Ang, Andrew Kishino and Ming-Na Wen. The new episodes air Fridays on Disney+.
