And finally we get to Drogon, the largest and meanest of the dragons from Game of Thrones. He is named after Daenerys' late husband Khal Drogo. Drogon is believed to be the reincarnation of Balerion the Black Dread, but Daenerys decides to give him a new name for his new life.
Drogon is slightly larger than his siblings. Most of his scales are black, shadowing red ones that run down his back and neck. His wings and frills are black-red mix, down to the wing-bones which are black. His eyes are orange-red. Over the course of the series he has grown considerably, from being roughly the size of a kitten in Season 1 to the size of a small whale in Season 5.
Drogon is the least shy of the three dragons when it comes to interacting with humans, albeit for the worst. He is by far the most aggressive of the three, easily agitated and quick to anger, as seen when he is a juvenile and he snarled at a Yunkai wise master when he approached Daenerys. He is also the first to react to orders and takes the initiative in confrontations, as seen when Daenerys ordered her dragons to burn Pyat Pree or when the Wise Master threatened her, he was the first to jump to his mother's defense.
He often seeks his mother's affection, and is often seen being caressed by her. However, even she isn't safe from his anger, as seen when he snarled at her without warning when she tried to defuse a conflict between the three. That said, he is fiercely protective of his mother, and will fight viciously in order to defend her, ignoring wounds if needed, as seen when he attacked the Sons of the Harpy in the Pit. It appears that he can sense when Daenerys is in danger, and if he does, he will rush to her aide. His larger size also makes him take a dominant role among his siblings, shown in how easily he stole a lamb from Viserion and Rhaegal, the latter two not daring to fight but instead squealing for him to share.
What a freaking boss dragon. He does what he wants when he wants, yet protects those he loves. Can't fault a dragon for just being a dragon, especially one as big as Drogon. My favorite moment was definitely when he appeared in the pit to save Daenerys, and then she rides off on his back. I can't wait to see what Season 6 has in store for him. Hopefully he eats Littlefinger or takes on the White Walkers at the Wall. I would settle for him destroying King's Landing too.
