|Portrayed by:||Nicole Oliver|
Eris is the goddess of strife and chaos, In the series she is Aphrodite's daughter, and Cronus' Granddaughter, Eris appears as a teenage punk who decides to wreak havoc on New Olympia with a magic cell phone ringer she received from Cronus. She describes herself as a "girl who's into anarchy and chaos and sunset walks through battle torn wastelands" and the "face that launched a thousand wars" and enjoys graffiti art. Her powers affect both the heroes and gods, causing the heroes to argue instead of working together. While Odie attempts to find the Goddess Harmony fix the problems caused by Eris, the others are forced to overcome the spell Eris has cast in order to stop her.
Her symbol is the golden apple, as it represents temptation and chaos. She was the one who caused the Trojan war when she wasn't invited to the wedding of Peleus and Thetis and threw the golden apple at her mother Aphrodite, and that was where she claimed her title as the fairest goddess of the gods. In turn Aphrodite accidentally contributed to the Trojan war and her daughter's curse as she made the bride fall in love with someone else, thus helping her daughter's desire for revenge come true.
- When Eris teleports, a hot pink-and-black Anarchy symbol (a circled capital A) appears in the location she leaves.
- In the show Aphrodite refers to Eris as "The worst daughter she ever had" for the terrible things she's done.
