The last known dragon before Drogon was a small, sickly female whose name is unknown, dying young during the reign of King Aegon III Targaryen (nicknamed "Dragonbane") around 153 AC, ending the lineage until Daenerys hatched her dragons centuries later. While Aegon III was the last rider, this female dragon was the last living creature of her kind in Westeros for over a century.
In the A Song of Ice and Fire novels, Balerion was the last surviving dragon from Valyria. When the Targaryens resettled on Dragonstone to escape the coming Doom of Valyria, they took five dragons with them, but four of these (whose names are not mentioned) later died, leaving only Balerion.
He is named after Daenerys's late husband Khal Drogo. He can be distinguished by his black and red colored scales, and red-black wings. He was also Daenerys's personal mount. With the deaths of Viserion and Rhaegal, Drogon is currently the last of his brothers, hence the only known living dragon in existence.
The only thing left of the race are petrified dragon eggs, which are used as decoration, and the bones which are used for weapon crafting.
During the battle, the Night King fatally wounds Viserion with an ice spear to the neck. Rhaegal swoops after him in a desperate attempt to help, but it's too late; he can only cry in despair as Viserion crashes through the frozen lake and slowly sinks into the waters.
There's no single "saddest" death, but Hodor, Shireen Baratheon, and Ned Stark are consistently cited due to their tragic innocence, shocking betrayal, or profound thematic weight, with Hodor's mind-bending sacrifice ("Hold the door") and Shireen's burning by her own father often topping lists for sheer emotional devastation, while Ned's execution defined the show's brutal realism.
Game of Thrones' Drogon chose not to kill Jon Snow because of his Targaryen blood, his love for Daenerys, and Drogon's possible understanding that while Jon committed the act, he wasn't the reason for Daenerys' death at the end of Game of Thrones'.
Vhagar was twice the size of Drogon and older/more experienced in battle. Wouldn't even be a close fight. Vhagar has upper hand that's for sure !!!
So the Velaryons are not exceptions. During the Dance of the Dragons, Hugh Hammer, Ulf the White, Addam of Hull, and Nettles were all found to be capable dragonriders. They were suspected to be Targaryen bastards, but never confirmed in the text. In particular, Nettles is sometimes pointed to as likely not a Targaryen.
Vhagar, [c] [d] called the Queen of All Dragons, is the dragon ridden by Visenya Targaryen during Aegon's Conquest. Although the smallest of the trio that included Balerion and Meraxes during this time, Vhagar was still large enough to swallow a horse whole, and her flames could melt armor.
Prince Rhaegar Targaryen, the last Prince of Dragonstone, was the eldest son and heir to King Aerys II Targaryen, the Mad King. He was the older brother of Viserys and Daenerys Targaryen and the husband of Elia Martell, with whom he had two children, Rhaenys and Aegon.
Balerion died less than a year after Viserys mounted him. Viserys' brother Daemon (Matt Smith) is also old enough to have remembered Balaerion, although he would have been quite young the last time he saw the beast alive.
From the beginning to the ending of Game of Thrones, it was Westeros that failed her, and Daenerys lost everything in her quest for the Iron Throne. So she finally snapped and unleashed all of her frustrations, grief, and pure rage on King's Landing.
The TV writers seem to be claiming that the Night King both raised Viserion back to life and turned him to some kind of dragon equivalent of a White Walker. Viserion probably won't die like this in future novels, and it may be an invention of the TV series.
Balerion lived to be just over two hundred years old, finally succumbing to old age during the reign of Aegon's grandson, King Jaehaerys I. His last rider was then-Prince Viserys I Targaryen, who claimed him in 93 AC.
Drogon: Comparing Size, Strength, and Significance Balerion, known as 'The Black Dread,' is considered the largest and most formidable dragon in the history of House Targaryen, surpassing even the mighty Drogon from the Game of Thrones series.
While all three dragons—Drogon, Rhaegal, and Viserion—are loyal to Daenerys, Drogon emerges early on as her favorite and most closely bonded companion. Named after Drogo, he reflects her fire, fury, and independence, often responding to her emotions with terrifying force.
Ned arrived just after the Lannisters; the Sack was still ongoing, and he found Jaime right after he killed Aerys. So, given that time line, if Ned had enough time to make it to King's Landing, it would appear that Rhaegar was killed first? Yup.
Specifically, after Daenerys conquers the city of 'Yunkai', the freed slaves greet her by calling her “Mhysa.” It symbolizes Daenerys as a liberating figure for them. She is seen as both a “savior” and a “mother”, someone who gives them freedom.
During the wedding, exiled knight Ser Jorah Mormont pledges his loyalty to Daenerys while her benefactor Illyrio Mopatis gifts her three petrified dragon eggs. Daenerys is afraid of her new husband initially, but after learning the Dothraki language, she begins to bond with Drogo and genuinely falls in love with him.
Balerion the Black Dread was the largest and most fearsome dragon ever to live, ridden by Aegon the Conqueror during his conquest of Westeros.
Dragon's potential strength and abilities to rival the legendary Pirate King Gol D. Roger. The Pirate King is considered one of the most powerful pirates in the series. However, the extent of Dragon's power and strength is unknown, which points to the possibility of him matching up against Roger.
There's no single "saddest" death, but Hodor, Shireen Baratheon, and Ned Stark are consistently cited due to their tragic innocence, shocking betrayal, or profound thematic weight, with Hodor's mind-bending sacrifice ("Hold the door") and Shireen's burning by her own father often topping lists for sheer emotional devastation, while Ned's execution defined the show's brutal realism.
Although viewers thought Jon would end up on the Iron Throne or as the king consort with Daenerys as queen, Bran was named the new ruler. After Tyrion was brought before a council in Westeros, he said there should be a vote, but his choice would be Bran because of his narrative and special skills.
In the end, Jon was spared a death sentence and instead ordered to rejoin the Night's Watch and head north of the Wall to spend the rest of his time.
