which dragon did viserys ride

Viserys I rode Balerion the Black Dread , the last dragon he ever bonded with. Balerion was already ancient by then, so Viserys only managed a very short flight before the dragon’s death.

Quick Scoop

• Dragon: Balerion the Black Dread.

• Rider: Viserys I Targaryen.

• Context: He never rode another dragon after Balerion died.

What that means

Balerion was the legendary dragon once ridden by Aegon the Conqueror, and by the time Viserys claimed him, he was already extremely old and weak. That’s why Viserys’s ride was brief rather than the kind of dramatic dragonflight people often picture.

TL;DR: Viserys rode Balerion.
