How Big Was Vermithor? Compared to Other Dragons in A Song of Ice and Fire

House of the Dragon is a series that’s full of different dragons that are going to be front and center during the Dance of the Dragons, which is the upcoming Targaryen civil war. As such, we can expect a lot of dragons duking it out in many different battles. One such dragon that we know is going to be shown in the Dance of the Dragons is Vermithor, who was one of the most legendary dragons during his time because of its size and fury. But how big was Vermithor?

Vermithor, called the Bronze Fury, was an incredibly large dragon that not a lot of other dragons could stand up to. Due to the fact that he was almost a hundred years old by the time of the Dance of the Dragons, Vermithor was incredibly large and was second only to Vhagar among the living dragons.

The fact that Vermithor is second to Vhagar means that this dragon is huge and is one of the many different dragons to watch out for in the Targaryen civil war. It’s also interesting to see just how big it is when compared to the other dragons, as a lot of the other living dragons in the series are already huge in their own right. Now, with that said, let’s look at how big Vermithor is.

How Big Was Vermithor?

Even though House of the Dragon focuses a lot on the political maneuverings of the two sides that are involved in the upcoming Targaryen civil war, we all know that the series will show us a lot of dragons because this was the time when there was still quite a number of dragons in the world. Of course, we’ve already seen a few of them, but we are expecting to see more in the upcoming seasons.

One such dragon that we know is going to play a crucial role in the Dance of the Dragoons is Vermithor, which is a legendary dragon due to its sheer size and strength. And this is where we get to know more about Vermithor, who is yet to appear in the series but is eventually going to be crucial in the upcoming war.

Vermithor was born during the time when Aegon the Conqueror was still the Lord of the Seven Kingdoms. During that time, Vermithor was probably still an egg when Jaehaerys was born, as it was customary for Targaryen babies belonging to the line of heirs to have a dragon egg by their bedside. In that regard, Jaehaerys was the first dragonrider of Vermithor, who was a male dragon that was called the Bronze Fury due to its bronze coloring and its incredible size.

Because Vermithor was incredibly big, he was a proper dragon for a king, as he was King Jaehaerys’s mount for 55 years. During Jaehaerys’s rebellion against Maegor the Cruel in 48 AC, he was already the third biggest dragon in the world, as only Balerion the Black Dread and Vhagar were bigger than him. That meant that it only took less than 20 years for Vermithor to grow into a huge dragon that was bigger than all of the other dragons except for the two that conquered Westeros together.

It took a while for Jaehaerys to find a new dragonrider as he spent almost his entire life in Dragonstone after the Old King’s death. This probably explains why none of the other Targaryens were able to claim him as their dragon, as he spent his entire life in Dragonstone, which was controlled by Rhaenyra’s faction, considering that she was the Princess of Dragonstone.

However, during the Dance of the Dragons, Prince Jacaerys Velaryon realized that there was a need for more dragonriders so that the Blacks could match the power of the Greens. That was when there were several people that tried to claim Vermithor, who did not have a rider for nearly 30 years.

By the time Hugh Hammer was able to claim Vermithor during the early part of the civil war, the dragon was already incredibly large and was nearly 100 years old. Vermithor was second only to Vhagar at that time. The only reason why Vhagar was bigger was the fact that she was already close to 200 years old. Had Vermithor lived longer, he would have probably exceeded Vhagar’s size and may have come close to Balerion.

Vermithor’s Size Compared To The Other Dragons

To understand just how big Vermithor is, let’s compare him to the other dragons in House of the Dragons.

Balerion

In terms of size, Balerion is still the gold standard among all of the dragons to ever set foot on Westeros. That’s because the Black Dread is still the largest and strongest dragon in history, and there is a good reason why this incredibly large dragon is still talked about with reverence during the time of Game of Thrones. No dragon in history has exceeded Balerion’s size, and that means that Vermithor isn’t as big as the Black Dread.

Vhagar

Vhagar was the closest dragon to Balerion in terms of size because she got to live for a very long time and was close to 200 years old at the time of her death. During Aegon’s Conquest, she was actually the smallest of the three dragons that the Conqueror brought to Westeros but was able to outlive Meraxes to become second only to Balerion. Vhagar was the only dragon that was bigger than Vermithor during the Dance of the Dragons.

Drogon

Drogon is still one of the biggest dragons in the history of Westeros, as he was said to be the reincarnation of Balerion due to how fast he was able to grow. Nevertheless, Drogon is smaller than Vhagar, who is only slightly bigger than Vermithor. As such, Vermithor is still bigger than Drogon. However, an older Drogon could end up becoming bigger than Vermithor ever was, considering that he was said to be the reincarnation of the biggest dragon of all time.

Caraxes

Caraxes the Blood Wyrm is one of the slenderest dragons in terms of its frame, as it doesn’t have the heft that some of the other dragons do. But the thing about Caraxes is that it is quite long due to how its head is several times longer than your average dragon. But, even though Caraxes is pretty large and long, it is still smaller than Vermithor, who is nearly as big as Vhagar. It was said in the book that Vhagar is about twice as big as Caraxes.

Meleys

Meleys was the dragon that we saw in episode 9 of House of the Dragon when Princess Rhaenys broke the dragon free and nearly killed the Greens in her escape from King’s Landing. Meleys had a head that was just as long as an average person, and that meant that this dragon was large enough to swallow an entire human being whole. But the fact is that Meleys is still smaller than some of the bigger dragons, which include Vhagar and Vermithor.
