Aegon VI Targaryen Is the son of Elia Martell and Rhaegar Targaryen. He was supposedly killed by Gregor Clegane during Robert's Rebellion, but it is revealed that, supposedly, this was not the case. Aegon currenty leads the Golden Company in an invasion of westeros, where he has taken several lands in the Stormlands, and plans to lay siege to the Baratheon seat of Storm's End. Given Aegon's parents, in actuality, he has a better claim to the Iron throne than any other character, even Daenerys Targaryen. However, this is all assuming that Aegon is who he claims to be, and not a pretender.
