As a fan of online novels, I don't have any specific preferences or preferences, but I can tell you some common villain names in novels. In some literary works, the villain would usually have an impressive name to attract the attention of the readers. Here are some common villain names in novels: 1 Odin: The supreme leader of the magical world who appeared in the Harry Potter series. 2 Devil (Devil Satan)(Satan): Appears in the Christian world as one of the fallen angels who later became the Lord of Hell. 3 Dark Lord (Dark King)(Lord of Darkness): The villain in the Dark Tower. 4 Ron Weasley: A friend and villain in the Harry Potter series. 5 Bellatrix Lestrange: The villain in the Harry Potter series is a very powerful wizard. Voldemort: The villain in the Harry Potter series is an ambitious and violent wizard. 7 Hermione Granger: The heroine in the Harry Potter series is also a smart and powerful wizard. 8 Aurora Babotter (Olog-O): The villain in the Defense Against the Dark Arts series. These names were very interesting and unique, able to attract the attention of readers. Of course, the villains in every literary work had their own unique names and personalities. The readers could choose according to their own preferences.
