Myrcella Baratheon is a fictional character in the A Song of Ice and Fire series of epic fantasy novels by American author George R. R. Martin, and its television adaptation Game of Thrones.

In her first appearance, she accompanies her parents, her two brothers (Joffrey and Tommen Baratheon), and her two "uncles" (Tyrion and Jaime Lannister) to Winterfell where Robert asks Eddard Stark to be appointed as Hand of the King.

During A Storm of Swords (2000), Trystane's sister Arianne Martell plans to crown Myrcella as Robert's heir instead of Tommen, hoping to incite the Dornishmen to rebel against the Lannisters to seat her on the Iron Throne.

In the ensuing confrontation, one of Arianne's co-conspirators, Ser Gerold "Darkstar" Dayne, attempts to kill Myrcella; although unsuccessful, he cuts off one of her ears and leaves her scarred.

"[4] Richardson learned about the recasting at San Diego Comic-Con;[3][5] in response, she posted a Vine video in which she wore a crown and held a sign saying "Princess for Hire".

Myrcella (now much older) is seen walking through the Water Gardens with Trystane, with whom she has fallen in love, while being watched by Ellaria Sand and Prince Doran Martell.

She is nearly taken hostage by Nymeria, but the conflict is interrupted after Areo Hotah arrives with a dozen Dornish guards, imprisoning Jaime, Bronn, the Sand Snakes and Ellaria.

[A][14][15][16] In Season 6, Episode 2, her body returns home to King's Landing shortly after her death, and her corpse, complete with stones over her eyes, is later seen in the Great Sept of Baelor.

[10] Myrcella is later avenged by Euron Greyjoy, who kills Obara and Nymeria in combat, and delivers Ellaria and Tyene to Cersei to exact her revenge.
