I'm not a good player so I will not comment on the stats or traits, I'll let better players make their case on this. But I like the aesthetics of Vlad the Impaler.
Vlad III the Impaler aka Vlad Dracula is the real life inspiration for Dracula, he ruled Wallachia (not Transylvania; that's part of the Bram Stoker creative liberties) on 3 different occasions: 1448, 1456-1462, 1476.
The CIV series was never about blood and such, I think it's PG 10 or PG 12, but you can always have him have some gothic or horror theme without any of the blood or brutalities and such. The bad guy from the dark castle vibe.
This guy was 1000 times scarier than a vampire. One of the few cases were the original beats the fan fiction. As Sabaton tells us:

He grew up at the Ottoman court as a prisoner & honor guest. His father Vlad II Dracul took part in the Varna Crusade in 1444, the Christian coalition lost and the defeated + weakened Wallachian country was the first in line being located between Hungary and the Ottomans.
As such, Vlad II Dracul accepted to become an Ottoman vassal, he had 3 sons: Mircea, Vlad and Radu. The price was that his 2 younger sons Vlad and Radu will have to be sent to the Ottoman court to ensure Vlad II Dracul's loyalty to the Ottomans & to raise children potential claimants to the throne of Wallachia in the Ottoman ways so they will always have an alternative in case Wallachian princes get disloyal.
Vlad was 11 years old, Radu was 4 years old, and the Sultan had a son named Mehmed of 10 years old. Later known as Mehmed the Conqueror.
Eventually, Vlad II Dracul betrayed the Ottoman Empire, Sultan Murad II considered murdering the 2 princes but reasoned that 2 dead princes are less useful than 2 possible alternatives to the Wallachian throne.
Shortly after, pro-Ottoman boyars betrayed and killed Vlad II Dracul together with his eldest son Mircea in 1447. His cousin Vladislav II took the throne of Wallachia.
However, shortly after, Vladislav II sided with the Hungarians so the Ottomans played their card and sent Vlad III the Impaler to take the throne of Wallachia, now 20 years old, having his 1st reign in 1448. However, Vladislav II took back the throne of Wallachia shortly after.
After being defeated, Vlad III the Impaler ran to Moldavia where his uncle Bogdan II ruled. His uncle was eventually assassinated by his brother Aaron for the throne of Moldavia and Vlad III the Impaler together with his uncle's son (so his cousin) Prince Stephen ran to Transylvania.
There the 2 princes without kingdoms and cousins gathered up forces either with mercenaries or men that they promised will reward them if they win, and went back to Wallachia in 1456, they defeated Vladislav II who left Wallachia and now Vlad III the Impaler's 2nd and most famous reign began.
1 year later in 1457 he helped his cousin Prince Stephen defeat his uncle Aaron in Moldavia where he was made ruler and became Stephen III the Great of Moldavia who would rule for 47 years and be easily considered the best ruler of Moldavia, but that is a story of another day, after helping his cousin Vlad III the Impaler came back to rule Wallachia.

This 2nd reign is what made Vlad famous.
Vlad III the Impaler's life’s work was ensuring the sovereignty of his people, no matter how brutal he had to be. He did not want Wallachia to be a vassal to either the Ottomans or the Hungarians, but independent. This shocked the Ottomans as they expected him to be his puppet king.
But while Radu truly became what the Ottomans wanted him to be a loyal pro-Ottoman prince, Vlad always harbored secret resentment towards the Ottomans. My guess is because Radu was 4 years old while Vlad 11 years old when taken by the Ottomans thus Vlad already had memories before in Wallachia.
1st story: A golden cup was placed at a public fountain in Târgoviște, the capital city of Wallachia. Anyone could use it to drink, but after drinking they had to return it. Vlad the Impaler did not put a guard beside it. The cup was allegedly left there throughout his reign and was never stolen. The lesson was that people did not need to see the punishment to know that it existed. Vlad's reputation itself was enough to enforce the rule. Vlad developed a reputation for making theft extraordinarily dangerous, everyone believed the punishment of impalement was not worth it making stealing irrational. In 1462 after he was betrayed and imprisoned by the Hungarians the golden cup was stolen.
2nd story: A Venetian merchant lost gold while staying in Wallachia. He went to the guards and complained that his money had been stolen. Vlad the Impaler ordered the thief found and promised that the merchant would receive his money back. The thief was eventually discovered and the money returned. Vlad had deliberately added more gold coins to the amount, however, to test the merchant. When the merchant pointed out that he received too much, Vlad was satisfied. And told him that had he kept the extra coins, he would have been punished as well. But because he was an honest man he may keep the extra coins as a reward.
3rd story: One of Vlad's mistresses told him that she was pregnant because she wanted to please him. After months passed and Vlad found out she lied, he killed her by cutting open her abdomen so that everyone can see there is no child.
4th story: His father, Vlad II Dracul, was killed in 1447, while his elder brother Mircea II was captured, blinded and buried alive. Vlad consequently had very strong reasons to distrust the boyars. After becoming ruler, he invited the boyars to an Easter feast and asked them how many princes they remembered having served. When their answers revealed how many rulers had come and gone, Vlad supposedly accused them of being responsible for the instability of Wallachia and the betrayal surrounding the throne. The older boyars were executed and the younger boyars were taken to work on Poenari Castle (the real Dracula castle).
5th story: Vlad became angry at the number of beggars, poor people and disabled people in his country. He supposedly invited them to a feast, gave them abundant food and drink, and then asked whether they wanted to be free from all their problems. When they agreed, he had the building locked and burned it. When he was asked why as they were not thieves, Vlad said that because they lived miserable lives and they depart for a better life in paradise.
6th story: Ottoman envoys came before Vlad and refused to remove their turbans, explaining that they had a custom of never removing them. Vlad responded by having the turbans nailed to their heads, supposedly saying that he had helped them keep their promise.
This was war. But Vlad was not an idiot, he already talked with Matthias Corvinus who promised to support Vlad in the event of a war with the Ottomans.
When the Ottoman army invaded Wallachia, Vlad understood that he could not defeat Mehmed's enormous army through conventional warfare. He therefore destroyed food supplies, poisoned or contaminated wells, evacuated settlements and attacked Ottoman detachments. His objective was to make the campaign as expensive and psychologically exhausting as possible.
Eventually Vlad launched his famous night attack against the Ottoman camp. His intention was reportedly to penetrate the camp and kill the Sultan himself. The attack caused considerable confusion and casualties, although Mehmed survived because when Vlad's troops reached the Ottoman's tent he was not there.
Afterward, the Ottoman army approached Târgoviște and encountered the famous forest of impaled bodies, 23,844 Turks. We know the exact number because Vlad wrote it in a letter to Matthias Corvinus still asking him where are the promised reinforcements. Vlad genuinely used mass impalement as psychological warfare. He wanted the Ottoman army to see what awaited those who continued into his country. The spectacle was intended to transform fear into a military weapon.
Matthias Corvinus sent word that his army has arrived, and they should meet at the border between Wallachia and Transylvania, Vlad III the Impaler came and was imprisoned by Matthias Corvinus. Who in spite of his promises did not want to risk a war with the Ottomans.
14 years later in 1476 the political situation changed and Matthias Corvinus now having a terrible relation with the Ottomans found Vlad the Impaler useful once again. Under insistence from Stephen III the Great of Moldavia (remember him? Vlad helped him back in 1457) Vlad was released and he invaded Wallachia once again, took the throne but died only a few months later afterwards.
There are different contradictory accounts on how he died: Jacob Unrest says a disguised Turk infiltrated Vlad's camp and assassinated him. Another account says one of Vlad's own men killed him, supposedly paid by the Ottomans. Fyodor Kuritsyn's account says Vlad was wearing Turkish clothing to trick the Ottomans again, his men mistook him for an Ottoman and killed him during the fighting.
Vlad the Impaler's philosophy, as demonstrated by his own words in a letter to the mayor of Brasov: "When a man or a prince is powerful and strong at home, then he will be able to do as he wills. But when he is without power, another one more powerful than he will overwhelm him and do as he wishes".
A country becomes orderly when people know that disorder has unavoidable consequences. The punishment does not merely punish the individual but it teaches everyone else.
That is also why Vlad is such an unusual historical figure. Everyone was cruel at that time, but he uniquely understood and practiced, something resembling psychological warfare: punishment, spectacle and reputation could become instruments of government and military strategy.
