Odalia Blight

Mama to Mittens, remember our deal. Make this look good, and we'll forgive your recent lackluster performance in school.

~ Odalia talking to Amity via her necklace.

“
What he does with our products is none of our business. What is my business is keeping our family ahead of the rest. You're welcome, everyone! [Alador gets mad] There you go, making that face. This is why I don't tell you things. With the emperor's favor, we'll live like royalty in the new world, crowns and everything!

~ Odalia revealing that she knew of Belos' plot all along, believing she and her family would be spared for their loyalty to him.

Odalia Blight is a supporting antagonist in the Disney Channel animated series The Owl House.
She serves as the overarching antagonist of "Understanding Willow", a flashback character in "Young Blood, Old Souls" and "Them's The Breaks, Kid", the main antagonist of "Escaping Expulsion" and one of the two main antagonists (alongside Kikimora) of "Clouds on the Horizon".
She is the abusive wife of Alador Blight, mother and archenemy of Amity, Edric and Emira Blight, and the CEO of Blight Industries. Unlike the other residents of the Boiling Isles, she is aware of the true, genocidal nature of the Day of Unity, but supports it under the false belief that Emperor Belos will spare her and her family and reward them by making them lesser royalty.
Personality
The one defining trait of Odalia is her social Darwinism; she is obsessed with always being on top, which was one of the main reasons she forced Amity to end her friendship with Willow. When she learns the truth of the Day of Unity, rather than being horrified, she instead assists Belos in carrying out the genocide of her own species under the false promise of her and her family becoming royalty in the new world. In addition, she is greedy, one instance being when she chides Amity for not focusing on one of her pitches.
Odalia is also a narcissist of the highest caliber; while she claims that she was looking out for the family's best interest by helping the Emperor, it is made clear that she was really only doing it for herself and tosses her own family away when they oppose her. She forces Amity to dye her hair green to resemble hers and appears to treat her children as her property that she can control (for instance, having Amity study feverishly and having her test out her company's latest Abomiton). Upon learning that Amity was dating Luz, she immediately rejects it because of Luz's status of being a criminal and states she would find a replacement for her daughter.
Prior to the events of "Clouds on the Horizon", her relationship with her family was tense. In her debut episode, she seems to care about her husband Alador, whom she listens to when he reminded her that a Blight always upkept their end of the bargain. However, as later episodes show, this is far from the case. She has her husband perform back-breaking work under the threat of having their kids be put in the factory (heavily implying child labor). When Alador learns about the true purpose of the Day of Unity, he tries to convince her to help them stop the event from happening. He expresses nothing but disgust towards his wife when she frankly admits that she had already known and chose to withhold it from him. From there, Alador quits his job (and likely their marriage), to which Odalia coldly says she was looking for a more competent assistant anyway.
Odalia also displays several traits of a sociopath: she has a high sense of self-importance; lacks empathy; demonstrates a superficial charm whenever she is advertising her company's products; and uses threats whenever things don't go her way. She has absolutely no qualm with trying to kill Luz with an Abomiton and appears to be unable to understand that her family rejected her offer of becoming royalty because they saw the plan as morally wrong. In a flashback to "Young Blood, Old Souls," Odalia can be seen in the stands watching the Emperor's Coven members harass Eda when she transformed into the Owl Beast with a smile on her face, suggesting that she was always deeply sociopathic and sadistic.
With that being said, Odalia seemed to have been on good terms with Alador and Darius when they were both attending Hexside years ago, and she is also featured in one of Eda's memories, implying that they were friends, or at least on good terms at some point. It is currently unknown what soured Odalia into becoming the narcissistic matriarch she is now.
Biography
Background
Not much is known about Odalia's past. What is known is that she was once an oracle student at Hexside along with Eda and Lilith Clawthorne, and her future husband Alador. Sometime after Lilith cursed Eda, Odalia married Alador, founded Blight Industries, and became the mother of three children: Emira, Edric, and Amity Blight.
Understanding Willow
She, alongside her husband Alador, forced Amity to end her friendship with Willow due to wanting to preserve their reputation as being "superior." When Amity refuses, Odalia threatens to prevent Willow from attending Hexside leading to Amity having to cut her ties with her childhood friend to protect her. She and Alador then arrange for Amity to befriend Boscha and the others due to the idea that they could mold her into being crueler and more ambitious.
Unbeknownst to her, Amity, thanks to Luz's intervention, was able to make amends with Willow.
Escaping Expulsion
Odalia and Alador are holding a private Blight Industries demonstration of a security Abomiton Soldier for investors and uses her daughter Amity to display its combat capabilities, but when Amity's photo of Grom night falls out of her pocket, she instantly destroys the abomination, causing the attendance to leave as sales for the Abomination plummet rapidly.
Odalia figures that Amity's friends are a distraction, and the next day, she forces Principal Bump to expel Luz, Willow and Gus from Hexside, as Amity watched regretfully. Luz confronts them as they leave, and Odalia offers Luz a deal to get them back in school: that she takes Amity's place in another showcase of Blight Industries' new weapons.
Luz agrees and takes a battering from the weapon demonstrations, struggling to resist with her glyphs, until a new Abomiton 2.0 model attacks her, which Odalia intends to have Luz completely eliminated with. However, Amity interferes, finally standing up to her parents and demanding they allow her friends back into school or else she will destroy the Abomination. Odalia falsely agrees, secretly intended to rescind the deal, but Alador reminds her that Blights always uphold their end of the bargain. Luz and Amity then feign defeat, allowing sales to go back up.
After this, Alador and Odalia are visited by the Golden Guard, They kneel before the emperor's emissary, who informs them that their weaponized products and efforts will now be sold exclusively to Emperor Belos, before warning them he does not take kindly to citizens producing a private army.
Through The Looking Glass Ruins
Odalia is mentioned when Amity styles and dyes her hair, revealing she dyes it green because her mother wanted her children "color coordinated", with Emira telling her "Mom will freak" when she sees it.
Reaching Out
Odalia briefly appears in a photo of a young Alador winning the Bonesborough Brawl years ago. When Amity was old enough to enter, she arranged her to try out for the Emperor's Coven on the same day. Near the end of the episode, it was revealed Amity never wanted to join the coven, it was Odalia's dream, not hers. It is also mentioned she is still trying to dye Amity's hair green.
Clouds On the Horizon
Odalia intimidates Alador by threatening to have their children work in the factory and ultimately reveals that she already knew that the Day of Unity was meant to kill all witchkind through the Draining Spell. However, rather than being appalled by it, Odalia instead was assisting the emperor in making the event happen under the belief that she and her family would be spared of the mass genocide, and they would rule as lesser royalty under Belos' new world order. This, of course, gives a lack of foresight that her family would also be in danger if she even cared.
When Alador finally stands up to her and tries to stop her, Odalia scoffs and leaves saying that she needed to find a more compliant business partner anyway. She also learns that Amity was dating Luz expressing disgust due to Luz's status as a criminal. Amity also states she would never talk to her again, effectively disowning her.
King's Tide
Although Odalia doesn't appear physically in the episode, she is briefly mentioned by Amity when Coven Guards confront them in the ship she and her friends stole, indicating she called them. She also appears briefly as a teenager in Eda's vision before beginning the plan to stop the draining spell, implying they used to be friends before Eda was cursed.
It is unknown what happened to Odalia when the draining spell occurred, although it's highly likely she was affected by it just like everyone else and was likely saved when The Collector stopped it before it was completed.
