what dragon is the dragon from first episode season 3 house of dragon

June 28, 2026

The dragon briefly shown in the first episode of House of the Dragon season 3 is Tessarion , the blue dragon bonded to Prince Daeron Targaryen.

That glimpse is meant to signal Daeron’s arrival in the wider conflict, and Tessarion is one of the key dragons on the Green side.

The season 3 premiere centers on the Battle of the Gullet and is packed with dragon combat, which is why that blue dragon stands out so much.

If you only noticed a quick blue dragon shot, that’s the one most recaps are identifying as Tessarion.

TL;DR: it’s Tessarion.
