Few fantasy worlds have captured our imagination like HBO's Game of Thrones, where dragons aren't just mythical beasts—they're weapons of mass destruction. Based on George R.R. Martin's novels, the franchise introduced us to the awe-inspiring creatures of House Targaryen, creatures that never stop growing throughout their centuries-long lives. From Daenerys's three hatchlings to the ancient titans of House of the Dragon, these fire-breathers come in all sizes. Let's count down the largest dragons to grace the screen, from the smallest of the big to the absolute behemoths.
10. Drogon
Daenerys Targaryen's beloved black-and-red dragon, named after Khal Drogo, is the poster child of the franchise. Hatched from a blood ritual, Drogon grew at an astonishing rate—reaching adult size in just a few years, unlike the slower-growing dragons of the Targaryen golden age. His rapid growth made him Daenerys's most powerful asset in her quest for the Iron Throne. While not the largest dragon ever, his speed and ferocity made him a force to be reckoned with.
9. Sheepstealer
A wild dragon from Dragonstone, Sheepstealer earned his name from his taste for mutton. In House of the Dragon, he wandered to the Vale of Arryn, becoming a nuisance to Lady Jeyne Arryn. Though he hasn't had much screen time, his gnarled, feral design sets him apart from the sleek royal dragons. He's larger than young adults like Seasmoke and Syrax, and fans hope Season 3 will showcase his full potential.
8. Caraxes
Known as the Blood Wyrm, Caraxes was ridden by Prince Aemon Targaryen and later by Daemon Targaryen. His long, serpentine neck and narrow jaws make him visually distinct, but don't let that fool you—he's a battle-hardened veteran. Caraxes and Daemon share one of the strongest dragon-rider bonds in the series, making them an unstoppable duo in the Dance of the Dragons.
7. Meleys
The Red Queen, with her striking red scales and crown-like spines, was ridden by Princess Rhaenys. Though age had slowed her, Meleys proved nimble and deadly in battle. At Rook's Rest, she nearly destroyed Sunfyre before Vhagar intervened, wounding the ancient dragon before her own demise. Her final fight cemented her as one of the most formidable dragons of her era.
6. Dreamfyre
One of the oldest second-generation Targaryen dragons, Dreamfyre was the mount of Princess Rhaena and later Queen Helaena. Her beautiful blue-and-silver scales made her a sight to behold, but decades in the Dragon Pit stunted her growth. Still, she remained a large and dangerous beast, capable of laying multiple clutches of eggs over the years.
5. Meraxes
Ridden by Queen Rhaenys during Aegon the Conqueror's invasion, Meraxes was the second-largest dragon of the Conquest. Her bloodline extended all the way to Daenerys, and she played a crucial role in unifying the Seven Kingdoms. Though her exact size is debated, she was a true titan of her time.
4. Syrax
Ridden by Princess Rhaenyra Targaryen, Syrax was a golden-scaled dragon known for her loyalty and power. While not as battle-scarred as some, she was a symbol of Rhaenyra's claim to the throne. Her size placed her among the larger dragons of the Dance, though she met a tragic end during the conflict.
3. Vermithor
The Bronze Fury, once ridden by King Jaehaerys I, was one of the largest dragons alive during the Dance. His immense size and strength made him a prized asset for the Blacks. Vermithor's roar alone could shake the earth, and his fire was said to melt stone. He was a true relic of the Targaryen golden age.
2. Vhagar
The undisputed queen of the Dance, Vhagar was the largest dragon of her era. Ridden by Visenya Targaryen during the Conquest and later by Aemond Targaryen, she was a living legend. Her sheer size made her nearly invincible in battle, and her fiery breath could decimate entire armies. Vhagar's presence alone could turn the tide of war.
1. Balerion the Black Dread
The largest dragon in Westerosi history, Balerion was the mount of Aegon the Conqueror. His skull in the Red Keep dwarfs all others, and his shadow could blot out the sun. Balerion's fire was so hot it could melt stone and steel, and he lived for over two centuries. No dragon before or after matched his sheer scale and destructive power. He remains the ultimate symbol of Targaryen might.
From the rapid growth of Drogon to the ancient terror of Balerion, these dragons define the Targaryen legacy. As House of the Dragon continues, we may see even more colossal beasts take flight.
