House of the Dragon season 2 will add at least 6 more dragons to the list. In season two, new dragons and characters will appear.
House of the Dragon has already boggled our minds with many complex names of dragons and human characters alike. HoTD Season 2 will be no different. In season 1 of House of the Dragon, we were first introduced to Syrax, the mount of Rhaenyra Targaryen. Other major dragons were Caraxes of Daemon, dragon Meleyes of Rhaenys Targaryen (the beast beneath the boards, as prophesied by Helaena Targaryen), dragon Vermax of Jacaerys Velaryon, dragon Vhagar of Aemon Targaryen (largest one in Westeros) and dragon Arrax of Lucerys Velaryon (whose death was altered in the series).
Other dragons have also been introduced in House of the Dragon so far, but haven’t received much screen time. In season 2 however, things will be different. Not only new dragons will be introduced, but new dragon riders as well. Daeron Targaryen, the third child of the late Viserys Targaryen will also be introduced. He was sent to Oldtown to study, which is why we don’t see Daeron in season 1. Hugh Hammer, a bastard son with Targaryen blood will also be introduced in HoTD season 2.
Aegon Targaryen, now that he loves the people’s attention as King, would like to (and does) participate ferociously. His dragon Sunfyre is described to have gold and pink scales and isn’t mono-coloured as the rest of the dragons. House of the Dragon fans will immediately fall for the beauty of Sunfyre, but not for its rider.
The best thing about the distinct look of Sunfyre is that it will be given much screen time, as the dragon is ridden by Kin Aegon II. As the major character, his dragon has major action scenes with Rhaenys and her dragon Meleys and even Rhaenyra on her dragon Syrax.
In a throwback to the original Game of Thrones, Dreamfyre, the dragon whose eggs were gifted to Daenerys Targaryen will be introduced. Daemon even steals one of her eggs early in the series. Pale blue with silver markings, Dreamfyre is bonded with Helaena Targaryen.
Mounted by Helaena Targaryen, Dreamfyre may not do much damage to The Blacks, as Helaena is shown, for a lack of better terms, kinda dumb. She was also shown to resent Aegon II and dancing with Jacaerys Velaryon in episode 8 of the first season of House of the Dragon.
The eldest daughter of Daemon, with his second wife Laena Velaryon, Baela rides the dragon Moondancer. A pale green dragon, funnily the size of a large horse, Moondancer may not be the ideal choice against Vhagar. But may prove to be agile against Dreamfyre or Tessarion, the dragon of Daeron Targaryen.
A medium-sized dragon, who may be able to compete against Vermax, Jace’s dragon. Tessarion is described as a bright blue-coloured dragon that is comparable to the size of Moondancer and may give tough competition to Vermax and even Syrax of Rhaenyra Targaryen. We will most probably have a scene in which all four Targaryen siblings (Aegon II, Aemond, Helaena and Daeron) are riding on their dragons.
Vermithor is that mysterious dragon from the season one finale to whom Daemon sings the Old Valyrian hymn. Originally King Jahaerys’ mount, Vermithor is the second-largest dragon after Vhagar, and he will prove to be an asset to The Black Council.
Hugh Hammer, the rider of Vermithor, is one of the dragonseeds, as described in Fire & Blood. Dragonseeds are those who have dragon blood in them and get a chance to claim the unclaimed dragons, though they are bastards.
Last and definitely the least interesting dragon Tyraxes, will not see much of war. Joffrey Velaryon, the third bastard child of Rhaenyra and Harwin Strong, is too young for battle during the Targaryen civil war. House of the Dragon will not alter the book’s storyline here and introduce Tyraxes to war, simply because it would be illogical for Rhaenyra to send Joffrey to war anyway. The most action that has been credited to Tyraxes in Fire & Blood is that he breathes fire on some rioters who come running towards him.
