In some ways they are as different as night is to day...
Aegon, who was born to be the 2nd of his name
Aegon, the 2nd of his name who was born for nothing
Aegon, the usurped
Aegon, the usurper
Aegon, who wanted the throne but was never able to take it
Aegon, who never wanted the throne but was given it
Aegon, who rode a silver dragon
Aegon, who rode a golden dragon
Aegon, who was named heir over his elder sister just for being born male
Aegon, who would have been named heir over his elder sister just for being born male if his father had been any other king, or if his mother had been his father's first Queen, the favored Queen
...yet in other ways, they're...
Aegon, who was named for the conqueror
Aegon, the second child & first surviving son
Aegon, who's terrible uncle's hated them for having a better claim to the throne
Aegon, who had 2 little brothers
Aegon, the son of a foolish weak king
Aegon, who was wed to his sister at 15
Aegon, who's sister wife rode Dreamfyre
Aegon, who became a father to twins by 16
Aegon, who didn't gave up on his goals
Aegon, who had to die, who's children had to die, to make space for someone better, and someone more important
...& their stories are the same.
