Vhagar is Westeros’ largest and most formidable dragon, instrumental in Aegon Targaryen’s conquest of the continent in 2 BC, the last living creature from that era.
She’s named after a Valyrian God. She's fought more than a 100 battles. Her fire breath can melt armor. Her roar can shake the foundations of Storm’s End. None of this matters on this internet, where you can find House of the Dragon viewers calling her everything from “Walmart-brand Godzilla” to “a hag” to “grandma”. And they don’t mean that last one affectionately.
