Daenarys’ dragons were born following the death of her husband Khal Drogo, as well as her brother Viserys, and her unborn child.
The three dragons are called Drogon, Rhaegal and Viserion.
When the dragons are tattooed solo (or with Daenerys) then it’s usually just the largest dragon Drogon – named after her husband – which is represented in ink.
Drogon is the most powerful of the three beasts and was most often the one Daenerys rode when she took to the air. He had black scales.
Rhaegal was a slightly greener color, named for Daenerys’ unborn son Rhaegar (also the name of her eldest brother), while Viserion was colored white and blue and was the smallest of the three. Viserion was named after her brother Viserys, who died when Khal Drogo poured a pot of molten gold over his head.
