Dragons in House of the Dragon are not interchangeable flying flamethrowers. They differ wildly in size, age, muscle mass, flight endurance, and sheer psychological impact. Some are weapons of mass destruction. Others are fast, vicious, and built for aerial murder rather than siege work.
This ranking weighs raw size, physical power, combat record, and narrative evidence from Fire & Blood alongside what the show actually puts on screen. If a dragon is terrifying but never tested, that matters. If one is old, scarred, and still winning fights, that matters more.
Vhagar
Rider: Laena Velaryon, later Aemond Targaryen
Size: Enormous
Status: Alive (as of Season 2)
Vhagar is the largest living dragon at the time of the Dance of the Dragons. Once ridden by Queen Visenya Targaryen during Aegon’s Conquest, she is one of the few dragons that fought beside Balerion the Black Dread. Though smaller than Balerion in his prime, Vhagar remains immense, seasoned, and devastating in battle. Her bond with Aemond makes her a formidable threat to the Blacks.
No dragon alive during the Dance comes close to Vhagar’s physical presence.
By the time of the civil war, Vhagar is ancient, battle-scarred, and enormous to the point of absurdity. In the books, she is described as being so large that her shadow swallows armies. The show reinforces this with scale shots that make castles look small and riders look temporary.
Why Vhagar sits at the top
- Large enough to crush other dragons outright in mid-air
- Firepower capable of obliterating fortifications, not just troops
- Combat veteran with multiple dragon kills
- Survived centuries of war, which matters in a fight
Vhagar is slow, but at this scale, speed is optional. When she hits something, it ends.
Vermithor
Rider: None (wild, formerly King Jaehaerys I)
Size: Huge
Status: Wild but approached by Daemon Targaryen
Vermithor, the Bronze Fury, is a massive dragon that once served King Jaehaerys I. After his rider’s death, Vermithor went unclaimed for decades. By the time of the Dance, he remains one of the oldest and largest dragons in Westeros. Only Vhagar surpasses him among living dragons, and in his youth, he was second only to Balerion the Black Dread, the largest dragon to ever fly.
Vermithor is raw power waiting to be unleashed.
Known as the Bronze Fury, Vermithor was ridden by King Jaehaerys I and spent decades growing massive without regular combat. By the Dance, he is second only to Vhagar in size, with a wingspan and bulk that dwarf most living dragons.
What makes Vermithor terrifying
- Near-Vhagar size with far more aggression once awakened
- Enormous fire output, described as furnace-like in the books
- Thick scales that shrug off damage from smaller dragons
The show hints at his potential rather than fully unleashing it, but book readers know Vermithor is less a dragon and more a walking extinction event.
Caraxes
Rider: Daemon Targaryen
Size: Large
Status: Alive (as of Season 2)
Known as the Blood Wyrm, Caraxes is aggressive, agile, and notably more serpentine than most dragons. His lean build belies his ferocity in combat. First ridden by Prince Aemon and then by Daemon, Caraxes is a battle-scarred veteran. Though not in Vhagar’s weight class, his speed and ruthlessness make him deadly in aerial engagements.
Caraxes is not the biggest dragon, but he might be the most dangerous in a fight.
Nicknamed the Blood Wyrm, Caraxes is long, lean, and visibly deformed, with an almost serpentine build. What he lacks in bulk, he compensates for with speed, agility, and violence. He is built to kill other dragons, not burn cities.
Caraxes excels because
- Exceptional aerial agility
- Extremely aggressive combat behaviour
- Proven ability to take down larger dragons through precision
In both book and show, Caraxes feels like a predator designed specifically to hunt his own kind. He is not pretty. He is not majestic. He is efficient.
Meleys
Rider: Rhaenys Targaryen
Size: Large
Status: Alive (as of Season 2)
Meleys, the Red Queen, is among the fastest dragons in the realm. Once ridden by Alyssa Targaryen and now by Rhaenys, she combines speed with striking beauty and deadly precision. Her dramatic emergence during Aegon II’s coronation is one of the most charged moments in the series so far, a reminder that old dragons are not to be underestimated.
Meleys, the Red Queen, is speed and strength blended together.
She is one of the fastest dragons alive during the Dance, but also large enough to physically overpower most rivals. The show presents her as muscular and compact, with explosive acceleration rather than long glides.
Why Meleys ranks high
- Faster than Vhagar and Vermithor
- Large enough to kill most dragons outright
- Highly experienced rider during the Dance
Meleys is the kind of dragon that wins fights quickly or dies trying. There is no cautious version of her.
Syrax
Rider: Rhaenyra Targaryen
Size: Medium to large
Status: Alive (as of Season 2)
Syrax is younger and less experienced than the elder dragons, but still powerful. She has been with Rhaenyra since the princess’s youth and is noted for her distinctive yellow colouring. While she has not yet seen full-scale combat, her bond with the rightful heir to the Iron Throne positions her as a key asset in the conflict.
Syrax is often underestimated, which feels unfair.
While she is not a frontline monster like Vhagar, Syrax is still a fully grown Targaryen dragon with enough size and firepower to devastate cities and armies. The show portrays her as broad-bodied and powerful, though less aggressive than war-hardened rivals.
Syrax’s real strengths
- Significant size advantage over younger dragons
- Strong endurance and stable flight
- Capable of large-scale destruction when unleashed
She is not built for dragon-on-dragon duels, but against anything else, she is overwhelming.
Seasmoke
Seasmoke sits in the middle ground of the dragon hierarchy.
He is large, fast, and battle-capable, but lacks the mass to dominate older dragons. That said, he is more than enough to obliterate ships, castles, and infantry formations.
Where Seasmoke stands
- Faster than most large dragons
- Smaller fire output than the top tier
- Effective in hit-and-run combat
Seasmoke feels like a modern fighter jet surrounded by flying battleships. Dangerous, but situational.
Sunfyre
Rider: Aegon II Targaryen
Size: Medium to large
Status: Alive (injured in lore)
Sunfyre is strikingly beautiful, covered in golden scales and rose-tinted wings. While he lacks the battle record of the older dragons, he is capable and devastating in flight. His youth and brilliance make him a symbol for the Greens, but his legacy is also marked by serious wounds sustained in the war, particularly in the books.
Sunfyre is visually magnificent and physically powerful, but inconsistent.
In the books, Sunfyre grows into a formidable dragon, though his combat history is messy. Injuries, recoveries, and moments of terrifying violence define him more than raw dominance.
Sunfyre’s mixed legacy
- Strong build and impressive firepower
- Survives injuries that should kill him
- Less reliable in extended combat
He is dangerous, but not predictable. That keeps him out of the top tier.
Arrax
Rider: Lucerys Velaryon
Size: Small
Status: Dead
Arrax is one of the younger dragons in the Dance, fast and brave but ultimately no match for Vhagar. His death over Shipbreaker Bay is one of the pivotal early moments of the civil war, underscoring the brutal imbalance between the younger dragons and the titanic veterans from the Conquest era.
Tyraxes
Rider: Joffrey Velaryon
Size: Young
Status: Alive (unproven)
Tyraxes is still maturing and has yet to be tested in combat. His role in the war is more about future potential than present strength. Like several of the younger dragons, his fate will likely depend on how long the war lasts.
Moondancer
Rider: Baela Targaryen
Size: Small and fast
Status: Alive
Moondancer is unusually swift and nimble, even by dragon standards. Though she is smaller than most adult dragons, her agility could prove decisive in specific combat scenarios. Baela is a fierce and determined rider, and their pairing may yet have an important role in the war’s later phases.
Legacy of Balerion the Black Dread
While Balerion himself is long dead by the time of House of the Dragon, his shadow looms over the entire age. No living dragon has ever equalled his size, power, or fearsome reputation. He was the mount of Aegon the Conqueror and the one who melted Harrenhal with dragonfire. The dragons of the Dance live in his wake, and comparisons to him remain a measure of greatness. Vhagar and Vermithor are the closest heirs to that legacy, survivors from his era and reminders of just how destructive Targaryen power can be when fully unleashed.

The Seven Swords Takeaway
Power among dragons in House of the Dragon is not just about size. Age, temperament, combat experience, and even rider behaviour all shape outcomes. Vhagar dominates because she combines all of it. Caraxes terrifies because he ignores the rules. Vermithor looms because he represents potential rather than memory.
The Dance of the Dragons is less about who has dragons and more about who has the right kind of monster at the right moment.
