I enjoy tearing down the proud and powerful, and there are none who deserve tearing down like Gaea and her giants. Still, I must warn you that I will not suffer undeserved success. Good luck is a sham. The wheel of fortune is a Ponzi scheme. True success requires sacrifice.

–Nemesis to Leo and Hazel, in The Mark of Athena

Nemesis (Greek: Νέμεσις) is the Greek goddess of retribution, vengeance, balance, and justice. Her Roman counterpart is also called Nemesis for revenge does not change from Greek to Roman myths, as revenge is universal, though she may also be equated with Invidia.[1]

Percy Jackson and the Olympians

The Battle of the Labyrinth

Although she was not seen in the series, she is the mother of Ethan Nakamura. Ethan tells Percy Jackson who his mother was right before swearing allegiance to Kronos and supplying the last piece to revive him. He tells Percy that he lost his eye shortly after learning who his mother was, saying that he found out what the meaning of the proverb, "An eye for an eye" the hard way. Later, Dionysus mentions that several of the minor Gods are joining the Titans during the Second Olympian War, including Nemesis.

The Last Olympian

While Ethan joins Prometheus in a peaceful talk with Percy Jackson, he claims that he and his mother are not respected. Percy calls Nemesis the goddess of revenge and wonders why she deserves respect, but Ethan tells him that she is also the goddess of balance as she causes the downfall of people with too much good luck. He also tells Percy that Nemesis took his eye as payment for he would one day bring respect to the minor gods. While Ethan saw an eye as a small price to pay, Percy does not see Nemesis as a loving mother for taking her child's eye.

Later, as Kronos starts to destroy the thrones of the gods in Olympus, Percy reminds Ethan that his mother was the goddess of balance and that total destruction is in fact, not balance. This convinces Ethan to turn away from Kronos, and attack the titan but he is eventually killed when Kronos tosses him off Olympus for betraying him. However, just like Nemesis promised, Ethan was able to bring respect to the minor gods by giving Percy the inspiration to ask for this change instead. Nemesis is one of the gods to receive a cabin at Camp Half-Blood .

The Heroes of Olympus

The Mark of Athena

Nemesis appears in The Mark of Athena on the same island as Narcissus, Echo, and Narcissus's fan club. Leo and Hazel find her opening fortune cookies and changing the fortunes from optimistic to pessimistic (although she does leave alone the fortunes which she believes are enough). Leo initially perceives her as his Aunt Rosa, while Hazel sees her as her former teacher, Mrs. Leer; each is someone the demigod in question hated. Nemesis reveals that, after Leo bombed New Rome with the Argo II, the gods of Olympus blamed Hera for the budding civil war between the demigods, causing the goddess to flee from Olympus. Nemesis states that because of this, they can expect no help from Hera, and instead, offers her aid to Leo and Hazel, as she considers it her duty to tear down the proud and powerful, and she counts Gaea and the giants as the worst of that category.

Nemesis tells Hazel that she must save Nico by July 1 at the latest, and informs Leo that he will soon face a problem he can not solve. Nemesis offers him her help, though she warns that it will come with a painful cost. She gives Leo a fortune cookie, stating that when he opens it, he will have the answer to his problem. With that, she sends the two demigods off to find Narcissus and Echo.

Later, in Rome, Leo finally breaks open his fortune cookie to find the code to unlocking an Archimedes Sphere (though Nemesis is apparently irritated that he used the cookie to find a code). Though he successfully activates the sphere and saves Frank and Hazel from the eidolons, Leo is wracked with guilt shortly after when Percy and Annabeth fall into Tartarus, believing that the loss of the two demigods was the price he had to pay for rescuing his two companions earlier. He then keeps Nemesis' word, telling her he will defeat Gaea and the giants as the rest of the Seven and Nico di Angelo set sail for the the House of Hades.

The Trials of Apollo

The Hidden Oracle

Nemesis is mentioned to be the mother of Damien White.


Nemesis always pays her debts, good or evil.

Ethan, to Percy

Nemesis is seen as a cold and even cruel goddess whose ruthlessness is not exempt from even her own children as shown when she took her son's eye as part of their deal. However, Nemesis does have a strong sense of honor as exemplified when she swore to her son that he would gain recognition from this same agreement. She enjoys tearing down the proud and powerful. Overall, she appears to be both fair and intense.


Nemesis has short, curly black hair. She wears a red jacket, black jeans, black boots, and carries a whip as well as owning a motorcycle.

Much like Aphrodite, who appears as someone the viewer loves, Nemesis will appear as someone the viewer wants to take revenge on. For example, when he met Leo, Leo thought she looked like Aunt Rosa, one he wanted to take revenge on. This means that she will always look different to different people. Even if the observer sees this person, Nemesis' clothes do not change and Nemesis herself does not seem to know who she is perceived as.

  • The swan: The animal that she transformed to in order to escape Zeus‘ romantic advances.

  • Venegance Manipulation: As the goddess of vengeance, Nemesis is able to control and manipulate vengeance.

  • Justice Manipulation: As the goddess of justice, Nemesis is able control and manipulate justice. No one seems to be immune to this, as her powers were able to effect even the Olympians, as it was the deal she made with her son Ethan that shifted the war and finally revived Kronos and made the Demigods recognized as she promised.
  • She can apparently tell someone their destiny as long as she receives adequate payment in return, as she told Ethan he would bring the minor gods respect in exchange for his eye.
  • Punishment Manipulation: Nemesis can create and manipulate punishments, controlling the severity of punishment, chancing the type of punishment from any action or even punish actions which usually result in rewards such as when she punished Narcissus.

Known Children


Ethan Nakamura

Nemesis never claimed Ethan so Ethan end up get stuck in the Hermes' Cabin, similar to what happened with many other demigods at Camp Half-Blood.

At some point, Ethan met Nemesis one day, and she promised that he would one day balance the world's power, in exchange for his left eye. She took his left eye and he wore an eye patch over it.
