User blog comment:Alwaysmore2hear/Nominate Your Essential Villains for the 2018 FANDOM 100/@comment-5032898-20180912023611

So far, this is my collection of proposals, mostly villains who debuts in late 2017-early 2018 or having memorable roles in 2018 medias:
 * Film:
 * Thanos, definitely, being the main antagonist in the entire MCU and manages to defeat the Avengers by the end of the film, while winning his goal with just one finger snap.
 * Live-Action TV:
 * Blood Stalk from Kamen Rider Build. The mysteries surrounding Blood Stalk as well as his true identity brings plentiful of shocking events, turning the story's tone into a much more interesting light.
 * Jerome Valeska from Gotham, due to his role in the second part of Season 4. Well, Jerome is not the Joker in Gotham (his brother is) but still he manages to cause the birth of the Joker in that series. What is more, I find more refercence of the Joker on Jerome rather than Jeremiah, and I think his character being truly enjoyable, one of the best versions since Heath Ledger's version.
 * Manga & Anime:
 * Charlotte Katakuri from One Piece is a good choice as well, for being both an impressive fighter and a rival towards Luffy, also showing honorable side towards both his enemy and his family. His fixation upon donuts and his scarred mouth is rather shocking but that doesn't matter. After all, he is the first One Piece villain that has a blood-boiling fierce battle against Luffy ever since Doflamingo.
 * Isaac Ray Peram Westcott from Date A Live, as recently, his arc finally reaches towards his end with his befitting demise and I'm really surprised that the battle against him lasted so long. Personally speaking, wthout Westcott making his debut in Volume 6, DAL will have no interesting and exciting plots as it is today, since he is the major reason for Kurumi's actions and the entire franchise's bad things. The later story also gives us his past, showing him to be a much more complicated person than we once thought, while still keeping his monstrosity and vileness untouched.
