10 Most Disturbing X-Men Villains

7. Shadow King

For all that the more physically grotesque mutants have managed to disturb readers over the years, there's another category out there that opens up all sorts of horrifying possibilities - the telepaths.

Yes, Marvel's most famous and beloved telepath may be Professor X, but have you ever considered what might happen were he to turn evil? Think about it - with that power, Charles Xavier could dominate the mind of whichever person he chose, causing unprecedented harm to his victim, or even using them to advance his own position - say, to attain fame and fortune.

Although the Shadow King has so far ignored the latter temptation, he has done the former time and again. They were the very first mutant evil that Xavier encountered, which inspired him to found the X-Men shortly thereafter. Still, even with the X-Men out there acting as a deterrent, the Shadow King has reemerged time and again, enacting unspeakable horrors on his victims as a literal manifestation of human nightmares.

(Oh, and I guess the razor sharp teeth and claws don't make things any easier either.)

Content Producer/Presenter

WhatCulture's very own resident movie guy, Ewan has been working in the content creation biz for over 10 years now, having started as a freelance contributor to WhatCulture Gaming all the way back in 2015. After graduating with a First-Class Honours in History from Northumbria University in 2017 (where he won a prize for a totally killer dissertation on the Watergate years), Ewan took on the role of Comics Editor at WhatCulture and quickly developed WhatCulture Comics into one of the biggest superhero-focused channels on YouTube. He followed this with a brief hiatus at Screen Rant in 2021, where he worked across the Gaming and Film sections as a writer and editor, before returning to WhatCulture as a Senior Content Producer / Presenter in 2023. He started his own podcast, We Love Dad Movies, in 2022, and has contributed several written pieces to the Eisner-nominated comics website Shelfdust as well. In his current role, Ewan incorporates his love of cinema, comic books, and history into written pieces and video essays for WhatCulture's Film & TV channel, as well as WhatCulture Gaming and WhatCulture Horror, with a particular focus on nineties-era Dad Movies, old school Westerns, and Golden Age Hollywood Noir. John Carpenter is his fave, and he thinks Batman Beyond should never have been cancelled. If that's your vibe, you'll probably like his stuff.
