Prince Aegon Targaryen, the son of the crown prince Rhaegar Targaryen, is an unseen character in Game of Thrones. He is deceased when the events of the series begin and is not expected to appear in the series.
BackgroundAegon Targaryen was the son of Prince Rhaegar Targaryen and Princess Elia Martell. He had an older sister, Rhaenys Targaryen, and a younger paternal half-brother, Jon Snow. For mysterious reasons, Rhaegar allegedly abducted Jon's mother Lyanna Stark, sparking a rebellion that ultimately deposed House Targaryen as the ruling house of Westeros. Rhaegar was killed by Robert Baratheon, who was Lyanna's betrothed, at the Battle of the Trident. Soon afterward, Aegon and Rhaenys were brutally murdered along with their mother by Ser Gregor Clegane during the Sack of King's Landing.
Had he lived and ascended the throne, he would have ruled as "Aegon VI".
Aegon is mentioned many times, along with his mother and sister, by his maternal uncle Oberyn Martell, who makes it quite clear that he wants justice for their deaths. He gets his chance to confront Ser Gregor when Tyrion Lannister demands a trial by combat to prove his innocence in the death of his nephew, King Joffrey Baratheon. Oberyn volunteers to be Tyrion's champion after learning that Ser Gregor will be fighting for the crown.
As the two champions commence battle at the trial, Oberyn identifies himself to the Mountain as the brother of Elia and reminds his opponent of the crime he committed against House Martell, saying, "You raped my sister, you murdered her, you killed her children." Despite wearing light armor and drinking before their fight, Oberyn initially gains the upper hand and proceeds to slowly cut down the Mountain all the while shouting in an ever louder voice, "You raped her! You murdered her! You killed her children!" Thinking his opponent to be fully incapacitated, Oberyn again demands the Mountain confess his crime and reveal who gave him the order, pointing accusingly at the Mountain's liege lord, Tywin Lannister. However, in his hubris Oberyn is unexpectedly caught off guard when the Mountain suddenly trips him up. Berserk with fury at nearly being killed by his opponent, the Mountain pins Oberyn to the ground and proceeds to gouge out his eyeballs, making him scream in agony, as he roars for all to hear, "Elia Martell! I killed her children! Then I raped her! Then I smashed her head...in like this!" He then crushes Oberyn's skull, effectively confirming the long-standing rumor of arguably his most infamous war crime.
In the books
In A Song of Ice and Fire, Aegon is the infant son of Prince Rhaegar Targaryen and Elia Martell. He was killed by Gregor Clegane bashing his head in against a wall - then while still covered in the gore of the baby's blood and brains, Gregor raped Aegon's mother and killed her (some say he cut her in half with his sword). In the books, Amory Lorch separately killed Aegon's sister Rhaenys, though the TV series just condensed this so Gregor killed both.
