Since its debut, House of the Dragon has captivated fantasy fans with its political scheming, family drama, and, of course, its magnificent dragons. The prequel to Game of Thrones, based on George R. R. Martin's Fire & Blood, centers on the Targaryen civil war over the Iron Throne. Queen Rhaenyra (Emma D'Arcy) fights to hold the crown her father chose for her, while King Aegon II (Tom Glynn-Carney) presses his claim with the backing of the Hightowers. But beyond the war for succession, the true stars are the dragons—creatures that have kept House Targaryen on top for over a century.
With a much larger roster than the three dragons in Game of Thrones, House of the Dragon has given each beast its own personality and power level. Some are battle-tested, others are untested but full of potential. Here's our ranking of the most powerful dragons in the series so far, from the youngest to the most fearsome.
13. Tessarion
Rider: Prince Daeron Targaryen
Known as the Blue Queen for her striking sapphire scales, Tessarion belongs to Prince Daeron (Benjamin Evan Ainsworth), the youngest child of Viserys and Alicent. Raised in Oldtown, Daeron has only recently taken to the skies on Tessarion, flying above the Hightower army as they march to war. While she hasn't seen combat yet, her nimble build suggests she'll be quick in the air. Daeron's uncle, Ser Gwayne Hightower, vouches for his combat skill, and the pair share a strong bond—a promising sign for future battles.
12. Vermax
Rider: Prince Jacaerys Velaryon
Vermax hatched from a cradle egg placed beside Jacaerys (Harry Collett) as a baby, proving his Targaryen blood despite rumors about his parentage. As the eldest of the younger dragons, Vermax was large enough to threaten an entire armada and fast enough to dodge projectiles. He carried Jace on diplomatic missions to Winterfell and the Twins, but tragically fell during the Battle of the Gullet—a reminder that even the mightiest can be brought down by chance.
11. Moondancer
Rider: Lady Baela Targaryen
Baela (Bethany Antonia), daughter of Daemon and Laena, received a cradle egg that hatched into Moondancer. This young dragon is one of the most agile in the series, with a distinctive frilled head and green-and-black striped body. Moondancer serves as a scout and escort for the Velaryon fleet, and she gets her first taste of combat at the Battle of the Gullet. Her rider's adventurous spirit matches her dragon's nimble nature, making them a duo to watch.
10. Syrax
Rider: Queen Rhaenyra Targaryen
Syrax, named after a Valyrian god, has been Rhaenyra's loyal companion for years. The two share a deep emotional bond—Syrax roars in distress when Rhaenyra is upset. Though she's a full-grown adult dragon, Syrax has never seen battle and rarely hunts, which could leave her vulnerable against more experienced fighters. Still, her size and Rhaenyra's love of flying make her a formidable presence.
9. Sunfyre
Rider: King Aegon II Targaryen
Sunfyre is often called the most beautiful dragon ever hatched, with shining golden scales and pink wing membranes. He shares an unusually close bond with Aegon II. At Rook's Rest, Sunfyre fought bravely against Meleys, holding his own before being severely wounded by Vhagar. His survival—weeks without food and a miraculous recovery—shows incredible durability, making him a dragon to respect even when broken.
8. Sheepstealer
Rider: None (wild dragon)
Sheepstealer is a wild dragon who earned his name by preying on sheep in the Vale. He's a cunning survivor, avoiding capture for years. When he clashed with Syrax, he proved he could hold his own against a queen's mount. His feral nature and lack of a rider make him unpredictable and dangerous—a wild card in the war.
7. Seasmoke
Rider: Ser Laenor Velaryon (formerly), Addam of Hull
Seasmoke was Laenor's dragon, and after his death, he remained riderless until Addam of Hull claimed him. Seasmoke is a seasoned dragon, having flown in battles during the Stepstones. His experience and loyalty make him a valuable asset to Rhaenyra's cause, though he's not the largest or most powerful.
6. Caraxes
Rider: Prince Daemon Targaryen
Caraxes, the Blood Wyrm, is Daemon's mount—a fearsome, battle-hardened dragon with a reputation for ferocity. He's been in numerous wars, including the Stepstones, and his long, sinuous body makes him a terrifying sight. Caraxes is one of the most experienced dragons in the realm, and his bond with Daemon is legendary.
5. Meleys
Rider: Princess Rhaenys Targaryen
Meleys, the Red Queen, is Rhaenys's dragon and one of the oldest and largest in the series. She's swift and powerful, with a fierce loyalty to her rider. At Rook's Rest, Meleys fought bravely against Sunfyre and Vhagar, nearly winning before being overwhelmed. Her death was a major blow to Rhaenyra's forces.
4. Dreamfyre
Rider: Queen Helaena Targaryen
Dreamfyre is Helaena's dragon, a beautiful blue-and-silver beast. Though she hasn't seen much combat, her size and age make her a formidable presence. Helaena's gentle nature may not lead Dreamfyre into battle often, but when called upon, she could be a devastating force.
3. Vermithor
Rider: None (formerly King Jaehaerys I)
Vermithor, the Bronze Fury, was the mount of King Jaehaerys I and is now riderless. He's one of the largest dragons alive, with a temper to match. His roar alone can shake armies. If someone claims him, he could turn the tide of the war.
2. Silverwing
Rider: None (formerly Queen Alysanne)
Silverwing was the dragon of Queen Alysanne, Jaehaerys's wife. She's a gentle giant, but her size and power are undeniable. Like Vermithor, she's riderless and waiting for a worthy Targaryen to claim her.
1. Vhagar
Rider: Prince Aemond Targaryen
Vhagar is the oldest and largest dragon in the world, having been ridden by Visenya Targaryen during the Conquest. She's a living legend, with a roar that can be heard for miles. Aemond (Ewan Mitchell) claimed her, and together they've become a terrifying force. Vhagar's sheer size and battle experience make her the most powerful dragon in House of the Dragon—a true titan that can decide battles on her own.
As the Dance of the Dragons rages on, these dragons will continue to shape the fate of Westeros. For more on the show's future, check out our analysis of Helaena's vision. And if you're hungry for more fantasy, explore epic fantasy series or fantasy adventure games.
