I deserve this throne. I was raised for it. Snatched from my parents by the Queen of Azgeda. I suffered her cruelty. I won the Conclave. The Ambassadors don't get to judge me, and neither do you.
— to John Murphy [src]

Ontari was a recurring character during the third season. She was portrayed by actress Rhiannon Fish and debuted in "Watch the Thrones".

Ontari was a Nightblood from the Ice Nation and after Lexa's death came to Polis in order to become the next Commander. However, she never won the conclave but simply killed all other Nightbloods while they were asleep. Moreover, she was missing the Flame that truly made someone a Commander.

Jaha managed to convince her to take the chip that allowed her to enter the City of Light and as a result of being controlled by A.L.I.E. she convinced most her people to also take the chip. When Clarke and the others were trying to put the Flame into her, A.L.I.E. told Jaha to kill her. The controlled Jaha then struck Ontari in the head, which rendered her brain dead.

She later died after her body was used as part of a blood transfusion directly with her heart to allow Clarke to accept the Flame.

Early Life[]

Ontari was born a Nightblood. As a child, she was taken from her family by Queen Nia of Azgeda, who then hid her status as a Nightblood from the Flamekeepers. Ontari grew up suffering under Nia's cruelty, which may have led to her brutal and sadistic nature in her later years.

Throughout the Series[]

In Watch the Thrones Ontari is seen standing guard in Queen Nia's chambers when Clarke enters with a proposition for the Ice Queen. Ontari becomes suspicious of Clarke's true intentions, when she wipes the blood on knife off on her sleeve, after cutting her palm to signify a blood oath between Azgeda and Skaikru. Ontari attacks Clarke and smells her sleeve. She then informs Nia that Clarke had poison on it. Nia tells Clarke that they could've been allies, but for this treachery, they are now enemies. Nia cuts Ontari's palm and spills her black blood on Clarke's face as a message to Lexa.

Later in the courtyard of Polis, Ontari stands next to Nia's throne and watches the match between Lexa and Roan. Ontari is completely shocked and surprised when Lexa throws a spear into Nia's chest and kills her.

In Stealing Fire, after Lexa is accidentally killed by Titus, Ontari sneaks into Polis the night before the contest to determine the new Commander and slaughters all the other Nightbloods in their sleep. Although she is now officially the Commander, Titus accepts Clarke's argument that she would never be chosen by the Flame, allowing Clarke to flee with the Flame and letting himself die so that he cannot be used against Clarke. Ontari is forced to make Murphy and Roan swear to keep this knowledge secret.

In Fallen, Murphy acts as a fake Flamekeeper to officially legitimize Ontari's role, helping her rehearse what she has to say in the Ascension ceremony.

In Demons, the City of Light residents learns of Ontari's deception after Murphy confides in Emori, unaware that she has been chipped. Using this knowledge, Thelonious Jaha not only has Murphy arrested, but convinces Ontari to take the chip, resulting in A.L.I.E. ascending to a position of complete control of the Sky People and the Coalition.

In Perverse Instantiation (Part 1), with all other known Nightbloods dead or unavailable, Clarke decides to take the risk of sneaking back into Polis to remove Ontari's chip, hoping that she can be persuaded to accept the Flame and use it to help them find A.L.I.E.'s kill switch. However, this plan backfires when Jasper is brought into the City of Light, with the result that the Coalition not only anticipate the plan, but Jaha strikes Ontari in the head with a pike, causing severe brain damage so that she cannot accept the chip.

In Perverse Instantiation (Part 2), Clarke, with Abby's help, used an exchange transfusion, similar to the ones done at Mount Weather, to replace her blood with Ontari's. This allowed Clarke to temporarily have the black blood and for her body to accept the Flame. However, it was only successful so long as Ontari's heart kept beating to let the blood flow into her system, requiring Abby to open Ontari's chest so that Murphy could pump her heart to keep blood flowing when her condition worsened. After A.L.I.E. is destroyed, Murphy stops pumping Ontari's heart and she dies.

In Memento Mori, Murphy tells Josephine Lightbourne about how Clarke defeated A.L.I.E., namely that Abby had him pump Ontari's heart so that Clarke could use her Nightblood. Josephine finds it "badass" but Murphy just calls it gross.


Ontari is ruthless and sadistic toward her enemies, but also has a soft spot for some people such as John Murphy; however, she threatens and even goes as far as to rape Murphy. Despite having suffered under Nia's cruelty, she remains loyal to her Queen. Ontari is shown to be very insecure about her position as a fake Commander. When she encounters a problem, her instinct is to take action immediately rather than thinking things through first.

Physical Appearance[]

Ontari is small to average size, with long brown hair, brown eyes and scars on her face.



Ontari was very protective of Nia and was deeply affected by her queen's death. She jumped on Clarke, putting a knife to her throat when she saw her, blaming her for Nia's death. In Fallen, Ontari says that she suffered from Nia's cruelty while growing up, which possibly led to her being loyal to Nia.


Roan was Ontari's King. She didn't agree with him on his ways of handling things and had always planned to become Commander so that he would bow to her and obey her orders.


Ontari strongly disliked Lexa since she was the one who killed Nia. Shortly after Lexa's death, Ontari did not waste any time in claiming her throne, wanting to become the next Heda.

Main article: Murphy and Ontari
"She's taken a liking to me."
- Murphy about Ontari[src]

Murphy and Ontari have a complicated sexual and abusive relationship. Upon meeting for the first time, Ontari verbally and physically abuses Murphy. Despite the abuse, they both flirt with each other. Ontari doesn't mind being naked in front of Murphy, and Murphy doesn't bother to look away. In Fallen, Murphy proposes to be Ontari's "fake flamekeeper" to her "fake commander". Reluctant at first, Ontari accepts his advice. Later that episode, Ontari chains Murphy while she undresses in front of him. She then proposes for them to have sex to which Murphy refuses, telling her about Emori. Ontari asks him if Emori would kill him for cheating on her and threatens his life. Murphy ends up letting her rape him while murmuring "the things I do to survive".

In Perverse Instantiation (Part 2), Murphy pumps Ontari's heart so that Clarke can use her Nightblood to destroy A.L.I.E. with the Flame. After Ontari dies, Murphy shows no real care for her loss beyond disgust at what he was forced to do.

In Memento Mori, Murphy tells Josephine Lightbourne about Ontari while preparing her to pose as Clarke. Josephine thinks that Murphy pumping Ontari's heart was badass but he just finds it gross and changes the subject.

John Murphy: "I'm guessing to know all the names of the dead Commanders you actually have to be one."
Ontari: "You're guessing? The Ambassadors are expecting me. I'll have to kill them all now."
John Murphy: "Seems a bit excessive."
Ontari: "I deserve this throne. I was raised for it. Snatched from my parents by the Queen of Azgeda. I suffered her cruelty. I won the Conclave. The Ambassadors don't get to judge me, and neither do you."
-- Fallen

Killed Victims[]

  • Seven Nightbloods (decapitated in their sleep)
  • Titus (indirectly; ordered Roan to put a knife to his throat)
  • Herself (indirectly; allowed Jaha to kill her while under control of A.L.I.E.)

Notes and Trivia[]

  • Ontari's name originates from Ontario, a lake and a Canadian province within Azgeda territory.
  • Ontari was snatched from her parents by Queen Nia because she was a Nightblood. Her existence was kept hidden from the Flamekeepers and she was trained in the Ice Nation instead of Polis.
    • Given her likely age, it is possible she would have fought in the same Conclave as Lexa and Luna if the Flamekeepers had found her before Queen Nia.
  • After Lexa's death, and Ontari's slaughter of the Nightblood children who trained in Polis, this meant her and Luna were the only two known Nightbloods at the time.
  • After her own death, Luna was the only known Nightblood left.
  • She serves as a recurring antagonist of Season Three.
