Aegon IV Targaryen, known as Aegon the Unworthy, was the eleventh Targaryen to sit the Iron Throne, and is considered to be one of the worst Targaryen kings. He sired numerous bastards, legitimizing them on his deathbed, an act that led to five Blackfyre Rebellions.
Well the three who are usually seen as the worst are Mad King Aerys, Maegor the Cruel, and Aegon the Unworthy, as their names might suggest. Aegon II/Rhaenyra as well, whoever you choose.
Jaehaerys I “The Old King” Targaryen
A king for the people, he united rival families, built the Kingsroad, and led a reign of peace and prosperity. Also known as Jaehaerys the Conciliator or the Wise, The Old King is a unique anomaly in the grand scheme of Westeros kings.
At the age of thirteen, Helaena was plumper than most Targaryens, and less striking as well. Nonetheless, she was a pleasant and happy girl, and all agreed she would be an excellent mother.
Arya Stark, while posing as a common serving girl in Lannister-occupied Harrenhal, reveals to Tywin Lannister that Visenya was a heroine of hers.
Aerys Targaryen is the last king of the Targaryen Dynasty, and one of the cruelest. He shows initial promise in his reign but quickly becomes unfair, cruel, and unpredictable. In particular, he develops a fondness for fire and uses it to burn people alive.
Throughout Game of Thrones, the ultimate way in which Daenerys Targaryen is shown to be a “true dragon” is by her resistance to fire. Dany is initially depicted as slightly resistant to heat, including warm baths and other fires.
TARGARYENS ARE NOT IMMUNE TO FIRE! The birth of Dany's dragons was unique, magical, wonderous, a miracle. She is called The Unburnt because she walked into the flames and lived. But her brother sure as hell wasn't immune to that molten gold.
Aegon I Targaryen
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 IV Targaryen, known as Aegon the Unworthy, was the eleventh Targaryen to sit the Iron Throne, and is considered to be one of the worst Targaryen kings. He sired numerous bastards, legitimizing them on his deathbed, an act that led to five Blackfyre Rebellions.
Sunfyre devoured Rhaenyra in six bites, leaving only her left leg below the shin. Prince Aegon the Younger was forced to watch his mother die, and Elinda Massey allegedly gouged out her eyes in horror.
As the geneticist Razib Khan points out, “Daenerys Targaryen's inbreeding coefficient is 0.375. Charles II, the last Spanish Habsburg, who was impotent ... mentally disabled and could barely walk, had a coefficient of 0.254.” What is an inbreeding coefficient?
Since the beginning of House of the Dragon, Rhaenys Targaryen (Eve Best) has been referred to as "the Queen Who Never Was." Best's performance has stolen more than one episode as she brilliantly plays the character's complexities.

In addition, Ser Barristan Selmy mentioned that she had executed 163 enslavers in Meereen. While this was a large amount of kills, most fans could justify them because she truly seemed to be a liberating force.
Vhagar was a she-dragon of House Targaryen. She was ridden by Queen Visenya Targaryen during Aegon's Conquest, alongside Aegon the Conqueror's Balerion and their sister Rhaenys's Meraxes. Other known riders of Vhagar are Prince Baelon Targaryen, Lady Laena Velaryon and Prince Aemond Targaryen.
A theory states that after the prophesied Doom of Valyria, the Greyscale disease originated among those ruined walls. Since the Targaryens have the old blood of Valyria flowing through their veins, it would not be a far stretch to imagine that Matt Smith's Daemon Targaryen is immune to the disease.
What has Daenerys said about her inability to have children? Dany saw Mirri's prophecy as a curse, and believes she will never be able to give birth to human babies. Instead, she considers her dragons to be her children. When warlocks of Qarth steal her dragons, Jorah tries to convince her to leave them behind.
Game of Thrones did a pretty good job setting up the idea that the Targaryens were inherently fireproof. We blame Daenerys (Emilia Clarke) for this notion. From the time she stepped into a scorching hot bath and languished in the water with nary an eyebrow raised, fans knew there was something special about her.
The great power of the Targaryens over Westeros is due almost entirely to their unique mastery of dragons. To mount a dragon, it is thought that one must have the blood of Old Valyrian dragonriders flowing through them. House Targaryen ruled Westeros as the only family with this ancestry,...
The Targaryen family hails from Old Valyria, where lighter skin tones and hair colours were particularly common. As a result, the family had white or silvery blonde hair. The Targaryens have been able to keep their distinguishing Valyrian characteristics due to years of inbreeding.
They were brought to the castle ward, where they found an injured Sunfyre and King Aegon II Targaryen. Prince Aegon watched in horror as Sunfyre devoured his mother. Aegon was forever mentally scarred, and this event cemented his later fierce hatred for and terror of dragons.
The Targaryens were one of the great dragonlord families, but far from the most powerful. They were the last dragonlord house to survive the Doom, as Aenar the Exile had led his family to Dragonstone twelve years prior. Riding three dragons, the Targaryens eventually conquered most of Westeros during Aegon's Conquest.
King Baelor the Blessed was the first and original Targaryen king to display the infamous madness. He was overzealously obsessed with religion and purity, to the point that he starved himself into an early grave because he believed that food is of this world, and that the material world is sinful.
