Who is your favorite Fury from Hades's Underworld realm?

Ha ha nice reason...Megaera was much more than just for that reason though...Megaera or Μέγαιρα, aka "the jealous one" is one of the Fates in Greek mythology. She is the cause of jealousy and envy, and punishes people who commit crimes, especially marital infidelity. Like her sisters Alecto and Tisiphone, she was born of the blood of Uranus when Cronus castrated him. In modern French (mégère) and Portuguese (megera), derivatives of this name are used to designate a jealous or spiteful woman. In modern Greek, Italian and Russian, the word megera indicates an evil and/or ugly woman. In Roman mythology, the Furies also known as the Dirae (The Terrible) (Erinyes or Erinnyes (The Angry Ones) in Greek mythology) are three sisters: Alecto (The Unceasing or The Endless who was their leader), Megaera (The Grudging or The Envious Rager) and Tisiphone (The Avenging or The Retaliator). There are two accounts of their creation. One account has it that they came into being when the blood produced by Cronus castrating his father Uranus splashed upon the Earth, Gæa. The other account has it that they were mothered by Gæa with air and bad human emotions and deeds such as murder, perjury, disrespect, ingratitude, harshness, and violation of filial piety and the laws of hospitality.They are the goddesses of revenge, sometimes called the daughters of the Night or Those Who Walk in Darkness. They haunt criminals, especially those who kill or commit wrongs against blood relatives, regardless of motivation, until they go insane and die. The Furies are untiring and persistent in their pursuit. They are impartial and indifferent, merely carrying out their duty. They continue to torment wrongdoers even after death, until the criminal shows remorse. Then, they become the Eumenides (The Kindly Ones, Protectors of the Suppliant, The Well-Disposed Ones) or the Semnai (The Venerable Ones). They were often referred to as Eumenides, as calling them Furies was concidered bad luck. The Furies have also been referred to as the Potniae (The Awful Ones), the Maniae (The Madnesses), and the Praxidikae (The Vengeful Ones). Vergil (or Virgil) placed them in the Underworld, tormenting sinners under the command of Pluto, but Greek poets often presented them as pursuing criminals on Earth, under the command of Zeus. However, the Furies are also said to steer the great goddess Ananke (Necessity), who is more powerful than even Zeus, in that he can not escape what is necessary. Megaera basically did punish for infidelity but she was also the Furies messenger she typically sent messenges from Hades to the Olympians as even Hermes did not frequent the Undeworld realm.She is also usually the first to resort to abusive punishment of the three Furies...

Yeah she is...I love succubi...In folklore traced back to medieval legend, a succubus (plural succubi) is a female demon appearing in dreams who takes the form of a human woman in order to seduce men, usually through sexual intercourse. In modern times, a succubus may or may not appear in dreams and is often depicted as a highly attractive seductress or enchantress, while in the past succubi were generally depicted as frightening and demonic. The male counterpart is the incubus. Religious traditions hold that repeated intercourse with an incubus or succubus may result in the deterioration of health, or even death.
Similar to a vampire, succubi also known as Lilith and the Lilin (Jewish) and Belili (Sumerian) draw energy from men to sustain themselves. The word is derived from Late Latin succuba "strumpet" (from succubare "to lie under", from sub- "under" and cubare "to lie"), used to describe the supernatural being as well. It is first attested from 1387.Throughout history, priests, and rabbis including Hanina Ben Dosa and Abaye, tried to curb the power of succubi over humans. Not all succubi were malevolent. Pope Sylvester II (999–1003) was involved with a succubus named Meridiana, who helped him achieve his high rank in the Catholic Church. Before his death, he confessed of his sins and died repentant.
Names of known succubi:
* Agrat Bat Mahlat
* Eisheth Zenunim
* Lilith
* Meridiana
* Naamah
According to the Kabbalah and the school of Rashba, the original three queens of the demons, Agrat bat Mahlat, Naamah, and Eisheth Zenunim and all their cohorts give birth to children, except Lilith. According to other legends, the children of Lilith are called Lilin.
According to the Malleus Maleficarum, or "Witches' Hammer", written by Heinrich Kramer (Insitoris) in 1486, a succubus collects semen from the men she seduces. The incubi or male demons then use the semen to impregnate human females, thus explaining how demons could apparently sire children despite the traditional belief that they were incapable of reproduction. Children so begotten – cambions – were supposed to be those that were born deformed, or more susceptible to supernatural influences. The book does not address why a human female impregnated with the semen of a human male would not produce a regular human offspring.It is believed by some in the field of medicine that the stories relating to encounters with succubi bear similar resemblance to the contemporary phenomenon of people reporting alien abductions, which has been ascribed to the condition known as sleep paralysis. It is therefore suggested that historical accounts of people experiencing encounters with succubi may have been in fact symptoms of sleep paralysis, with the hallucination of the said creatures coming from their contemporary culture...awesome creatures I have a book on both the succubi and incubus...maybe you would take an interest in the Rusalka...
