The Biggest Dragons In Game Of Thrones & House Of The Dragon

Includes SPOILERS for House of the Dragon season 2, episode 4.


  • House of The Dragon breathes new life into Westeros, showcasing the terrifying Dance of the Dragons era with more dragons and riders.
  • Dragon sizes and ages play a crucial role in determining their power, history, and impact on the events within the series.
  • Each dragon in House of The Dragon boasts unique designs, colors, and sizes, adding variation and intrigue to the magical world of Westeros.

The biggest dragons in Game of Thrones add to the fantastical elements of the series, showcasing the amazing power of these beasts and their history in Westeros. House of The Dragon breathed new life into Westeros, continuing the story with one of the most horrific stories in Game of Thrones history. This was the time when the Dance of the Dragons took place, which saw the tragic deaths of some breathtaking dragons from GoT lore. The prequel show also boasts far more dragons than its original HBO parent show.

Dragons in George R.R. Martin’s world continue to grow as they age, so the dragon’s age can be an indicator of its size.

House of The Dragon takes place during the height of the Targaryens’ power in Westeros. It was a time when there were dozens of Targaryen dragon riders, and these dragons grew to a monstrous size. The first season introduced audiences to several dragons, and season 2 has continued the trend with even more. All the dragons currently in House of the Dragon stand out with distinct designs, colors, and sizes, allowing more variation than the three dragons Daenerys has in Game of Thrones


House Of The Dragon Season 2 Is Fixing A 6-Year-Old Rhaenyra Targaryen Complaint (& It’s Great For Season 3)

House of the Dragon season 2 will continue to make changes to George R.R. Martin’s Fire and Blood, and further improve Rhaenyra Targaryen’s story.

20 Tessarion

Dragonrider: Daeron Targaryen

Also known as “the Blue Queen,” Tessarion was a dragon ridden by Daeron Targaryen, the youngest child of King Viserys I Targaryen and Queen Alicent Hightower during the Dance of the Dragons. While far from the largest dragon to roam Westeros, Tessarion is large enough to be a real threat. While neither Tessarion nor Daeron has appeared in House of the Dragon, the showrunners revealed they haven’t been excluded from the series entirely, but have been in Oldtown.

19 Arrax

Dragonrider: Lucerys Velaryon

Lucerys Velaryon and Arrax flying in the rain in House of the Dragon's season 1 finale

Arrax was the dragon of Lucerys Velaryon and was one of the youngest alive at the time of its death. Arrax likely hatched just over a decade before its death, meaning it was old enough to be ridden but far too small to contend with the far more enormous dragons in the Dance. Vhagar, the biggest dragon still alive during House of the Dragon, makes quick work of the young Arrax, killing it with one bite.

18 Grey Ghost

No Dragonrider

Dragons flying to Dragonstone in Game of Thrones

Grey Ghost is a reclusive wild dragon that resides near Dragonstone. This creature got its name due to its scale coloration, which was a mixture of grey and white. While Grey Ghost has only been featured briefly in House of the Dragon, the original novella reveals that he is killed by Sunfyre, Aegon II’s dragon, in a fight. ​​​​​​While Grey Ghost is not the biggest dragon in the franchise, he was younger than other, larger dragons and, therefore, might have grown larger had he reached full maturity.

While Game of Thrones earned its reputation for outstanding political intrigue and character work, it also has some epic fantasy dragon scenes.

17 Quicksilver

Dragonrider: Aenys I Targaryen & Aegon Targaryen

Quicksilver is an ancient dragon from Westerosi lore, having been bonded to a member of the original Targaryen dynasty. She served as the personal dragon of King Aenys I and his son Prince Aegon Targaryen. She was a quarter of the size of the dread dragon Balerion, who was the dragon that killed her. Being close in size to Balerion is no small feat, as the larger dragon was considered to be one of the biggest dragons in Game of Thrones. Their battle was the first time since the Doom of Valyria that two dragons fought in the skies.

16 Vermax

Dragonrider: Jacaerys Velaryon

Vermax in House Of The Dragon.

Vermax hatched around the same time as Arrax and went to the older Jacaerys Velaryon, Rhaenyra’s eldest son and heir. Vermax is praised in Fire & Blood for growing quickly throughout the Dance, mirroring its rider in an attempt to rise to the occasion of war. However, compared to the older dragons present, Vermax is still quite small in comparison.

15 Moondancer

Dragonrider: Baela Targaryen

House of the Dragon season 2 Moondancer

Moondancer is a dragon in the House of Targaryen, and she was bonded to Baela Targaryen. She is a pale green dragon with pearl-white highlights. She is a young and slender dragon, which makes her fast and maneuverable. Moondancer is too young to be ridden in Fire & Blood, but the television adaptation has aged up the green dragon, allowing Baela to quickly join the action of the Dance. Moondancer is still young and slender, but she and Baela are shown to be quick and formidable.

14 Syrax

Dragonrider: Rhaenyra Targaryen

Named after a Valyrian goddess, Syrax is the dragon ridden by Princess Rhaenyra Targaryen, both in her youth and during the war. Syrax will fight alongside Rhaenyra as the Dance of the Dragons kicks off. Though not as big as others in her day, Syrax is certainly formidable and will doubtlessly serve to be quite a soldier during the war. She is also a young dragon, around the same age as the Princess, and she didn’t grow as big compared to others as she was mostly kept in chains and never had to hunt for her food.

13 Sunfyre

Dragonrider: Aegon II Targaryen

Sunfyre is one of the more beautiful dragons in Game of Thrones lore, with his glimmering golden scales being counted worthy of hosting King Aegon II Targaryen. Sunfyre is a fair bit bigger than Tessarion, the dragon ridden by Aegon’s brother, Daeron, but far smaller than Aemond’s Vhagar. Sunfyre’s size is shown in House of the Dragon season 2, episode 4 when matched up in combat against Rhaenys’ Meleys, who’s a fair bit bigger and better trained in combat.

12 Drogon

Dragonrider: Daenerys Targaryen

Drogon was born in the Dothraki Sea, and he was commanded by Daenerys Targaryen. She named him after her late husband, Khal Drogo, and some believe that Drogon might be the reincarnation of Balerion the Black Dread, the largest known dragon in history. Drogon was also the most famous of the dragons that appeared in the TV series, known as the possible last dragon. Drogon was the largest and the most aggressive of Daenerys’s three dragons, and she often has trouble controlling him. With his wings stretched twenty feet across, he is also her biggest dragon.

11 Seasmoke

Dragonrider: Laenor Velaryon

Seasmoke the dragon flying in House of the Dragon season 1-1

Seasmoke is one of the more battle-experienced dragons during the Dance due to fighting in the War of the Stepstones with its first rider, Laenor Velaryon. Following Laenor’s death in House of the Dragon season 1, Seasmoke has become riderless. At roughly 34 years old, Seasmoke is of significant size and is regarded as being fierce and quick. The dragon is described as being roughly a third the size of Vermithor, who’s one of the largest alive.

10 Meleys

Dragonrider: Alyssa Targaryen, Rhaenys Targaryen

Known as “The Red Queen,” Meleys was one of the first dragons to die in battle during the Dance of the Dragons. In House of the Dragon, she is ridden by Princess Rhaenys Targaryen, with an explosive scene in season 1’s penultimate episode. She makes a valiant effort to defend the Blacks’ castle in the Battle of Rook’s Rest, ultimately leading to her death. What Meleys lacked in size, she makes up for in speed and is known as one of the fastest dragons in Westeros, allowing her to contend with Vhagar in direct combat.

9 Caraxes

Dragonrider: Aemon Targaryen, Daemon Targaryen

With a nickname like “The Blood Wyrm,” it’s clear that while Caraxes might not be one of the bigger dragons on Game of Thrones, he was regarded as one of the fiercest and was beloved by the two Targaryens who bonded with him, Aemon and Daemon. At the start of House of the Dragon, Caraxes was as big as Drogon was in Game of Thrones season 8, which was around 100ft long. However, while the same size at that time, he was slimmer. By the time the Dance of the Dragons arrived, he was about half the size of Vhagar.

8 Dreamfyre

Dragonrider: Rhaena Targaryen, Helaena Targaryen

Dreamfyre breathing fire in House Of The Dragon.

Dreamfyre is the original dragon of Rhaena Targaryen, which, despite never fighting in great battles, was considered to be as beautiful as any of the Targaryen dragons and was a source of pride to her two riders. While Dreamfyre did not fight in the Dance, she looms large in the story of that war. Many characters are drawn to her silvery-blue coloring and believe that, in time, Dreamfyre could become a powerful weapon. She has still yet to appear fully grown in House of the Dragon, but her older age implies she’s quite massive.

7 Silverwing

While Silverwing fought in several battles, she is one of the very few dragons who survived the Dance and was sought after by several dragon-less Targaryens thereafter, lasting in legend long after the age of dragons had ended. Silverwing was considered an older, almost stately dragon and lived to be around 93 years old. King Jaehaerys’ queen, Alysanne Targaryen, rode Silverwing, and he developed a strong bond with Vermithor as well, as they coiled together at night when sleeping.

6 Sheepstealer

Dragonrider: Nettles

One of the mysterious, riderless, wild dragons, Sheepstealer famously avoided humans but, unsurprisingly, loved mutton, earning his name. He was also one of the few dragons to be ridden by a non-Targaryen, instead bonding with a young girl known as Nettles in Fire & Blood. Time allowed this dragon to grow in size and play a small role in the Dance when the girl Nettles tamed the beast with gifts of fresh sheep.

5 Vermithor

Dragonrider: Jaehaerys Targaryen

Among some of the biggest dragons in Game of Thrones, the bronze dragon Vermithor was ridden by great kings like King Jaehaerys Targaryen, the man who preceded King Viserys Targaryen. Vermithor isn’t as big as Balerion, and the Bronze Fury is a little smaller than select others in Game of Thrones history. He has huge wings and was almost 100 years old when the Dance of the Dragons began. He eventually proved to be instrumental during the Dance, dwarfing dragons like Daemon in comparison.

4 The Cannibal

The Cannibal earned his name for his habit of eating the remains of other dragons and even some of the hatchlings. He was one of the few dragons that were never ridden and was sometimes considered to be a threat to certain other dragons, including Grey Ghost. Easily the most mysterious of all the dragons, little is known of the Cannibal save his savage behavior toward other dragons and humans who bother him. He was able to grow to a truly terrifying size, and if he ever died and stopped growing is still up for debate.

3 Vhagar

Dragonrider: Visenya Targaryen, Laena Velaryon, Aemond Targaryen

First ridden by Aegon the Conqueror’s sister/wife, Vhagar fought in more battles than any other Targaryen dragon and was the largest known dragon in the world when the Dance officially began, making her a major threat in battle. In House of the Dragon, Vhagar is the size of Balerion during Aegon’s Conquest, contributing to Aemond Targaryen being one of the most powerful characters alive and an enormous threat to Rhaenyra’s chances at winning the throne.

The spectacle of Vhagar’s big scene in House of the Dragon’s season 1 finale impressively overshadows each scene of Dany’s dragons in Game of Thrones.

2 Meraxes

Dragonrider: Rhaenys Targaryen

Queen Rhaenys Targaryen & Meraxes' Deaths after Aegon's Conquest

The first of the three dragons that were ridden by King Aegon The Conqueror and his three sisters, Meraxes died over 100 years before the events of House of The Dragon, serving as an important piece of Westeros history. When the first Targaryens and their allies, the Velaryons, first invaded Westeros, Aegon’s sister/wife Queen Rhaenys Targaryen rode the silver dragon into battle during the Conqueror’s Balerion, and this was a battle where she and the dragon were killed. Meraxes was bigger than Vhagar, as told in the A Game of Thrones novel.

1 Balerion

Dragonrider: Aegon The Conqueror, Viserys I Targaryen

Known as “The Black Dread,” Balerion was the biggest of the Targaryen dragons and is one of the biggest dragons in Game of Thrones. Balerion’s name has withstood history in Westeros, with even those in the age after the dragons died remembering this mighty creature. The only Targaryen dragon that was born in the Freehold of Valyria, Balerion, in his prime, was an unstoppable force on the battlefield. Aegon the Conqueror rode The Black Dread into battle during his war to unite Westeros under his rule, and his mere presence caused great armies and kings to bend their knees.
