Question: is aegon vi a blackfyre?
Answer: Aegon (Little Griff) is not actually the baby of Rhaegar Targaryen and Elia Martell, but is a Blackfyre impostor that Varys and Illyrio Mopatis are propping up as a real Targaryen. He is descended from the female Blackfyre line (all the males were killed). ... Some think Varys may also have Blackfyre blood in him.
