Viserys Targaryen
Viserys Targaryen is Daenerys’ older brother and Rhaegar’s younger brother. He is the son of the Mad King known for his madness, and, unfortunately, Viserys inherited this madness his father had. Obviously, this does not bring any happiness to him or to his sister.
Viserys is extremely full of himself, arrogant, manipulative, and whiny. He believes that he is a great warrior like his brother was and thinks that everyone should obey him just because he has Targaryen blood. He is also very naive which makes him see the world only the way he wants to see it.
Aerys II Targaryen
Rhaenys Targaryen
Even though she did not appear in the show, she is probably one of the most important figures in the lore of the books and the show. Besides, Rhaenys Targaryen was mentioned several times by different characters. She is the younger sister of Visenya Targaryen and Aegon the Conqueror (to who she was also married).
Duncan Targaryen
Duncan Targaryen could have been destined for great things, but love got in the way. Perhaps it was incredibly brave and intelligent to throw away a proposed marriage in favor of the love of a non-royal, but others might suggest that this was a dangerous and stupid move to make. It did lead to chaos, bloodshed, and the potential for mass instability, but Duncan’s abdication was ultimately the right decision for himself. His intelligence is thus up for debate, but the legacy of the man is of a tactical fighter and victor in a number of small-scale battles and large tournies. However, he was not minded enough to defeat Ser Barriston in one of his final defeats.
Rhaella Targaryen
Aegon Targaryen
Known throughout the show as Jon Snow, Aegon Targaryen is the son of Rhaegar Targaryen and Lyanna Stark, which means he is the older brother of Daenerys. For the sake of clarity, it’s better to refer to him as Jon Snow because, even though after he found out about his parentage, he stayed true to his Stark upbringing.
Jon might not know many things, but he is still mature beyond his years. Because he grew up as a bastard, he had to learn early how to navigate the Stark household. Jon has made many mistakes as a leader, which even led to his murder at some point, but he was still smart enough to survive the Game of Thrones and do the right thing in the end by killing Daenerys and preventing her from becoming a tyrant.
Daenerys Targaryen
Visenya Targaryen
Another character that did not appear on the show but was mentioned several times is Visenya Targaryen. She was the eldest of the three Targaryens that rules during Aegon’s Conquest. She was the more warrior-like of the two sisters, which is probably the reason why Arya named her as her idol. Visenya played an integral part in the conquest of Westeros and even single-handedly took the Vale of Arryn with her forces. She was a skilled warrior and extremely smart, too, which is why she was admired by both of her siblings and valued by her brother and husband for her sharp mind.
Rhaegar Targaryen
Those who knew Rhaegar described him as a very intelligent and well-educated young man who was very kind and didn’t like fighting despite being a great warrior. Rhaegar would also go out to the common people, sing, and give out as money to the poor as he could.
Aegon I Targaryen
Also known as Aegon the Conqueror, Aegon I Targaryen did not appear on the show either, but he has been referred to many times as one of the earliest kings of the kingdoms. Aegon’s intelligence is pretty obvious considering the fact that he managed to conquer all of Westeros (except for Dorne) and then rule over them wisely until his death. Aegon’s rule lasted for thirty years after he was done with the conquest. Unfortunately, after his death, a war ensued because of his sons being rejected due to their incestuous origins. Nevertheless, Aegon is definitely the second most intelligent Targaryen right after Aemon.
Aegon V Targaryen
The younger brother of Aemon, and the unlikeliest king of all, Aegon was incredibly well-educated in his youth and was known to be quick-witted. In fact, his words could certainly get him into trouble, but he was always intelligent enough to back out of his self-made traps. Once king, Aegon was beloved by the people and wise in his rule. He might have had to contend with various uprisings, but ultimately it was a peaceful time that was aided by Aegon’s political know-how and ability to compromise. As Targaryen leaders go he was one of the most considerate and certainly took after his brother in seeing the bigger picture.
Aemon Targaryen
Not many people knew that Maester Aemon was actually Aemon Targaryen. This secret was revealed to Jon Snow a little prior to Maester Aemon’s death. You could say that it was strange for Aemon to choose the Night’s Watch over the throne, but it was actually a very wise decision. Aemon was a very wise old man who had an excellent education and would always help with advice. Before he became this wise person, Aemon had several opportunities to become King of Westeros, but he declined, believing that this would not bring any good neither for him nor for the realm.
