A form of NamesToRunAwayFromReallyFast.

XtremeKoolLetterz make an otherwise-ordinary name scarier. Most people with names that ''haven't'' been legally changed to have loads of "Kool Leturz" are best kept an eye on.



[[folder:Anime and Manga]]
* Xellos (Merry demon from ''Anime/{{Slayers}}'')
* Xanxus of ''Manga/KatekyoHitmanReborn'' is the incredibly badass leader of the Varia, an elite assassination team primarily employed by the most powerful mafia family in the world. He has some [[http://i7.photobucket.com/albums/y271/Green09/01-1.jpg amazing full-body scars]], and he spends most of his time throwing blunt objects at his subordinates and breaking their faces with tables.
* Subverted with Zagato of ''Manga/MagicKnightRayearth''. It seems at first that he is the main villain, but then the plot twist happens.
* Izumi Curtis from ''Manga/FullmetalAlchemist''. BadassTeacher, HandicappedBadass, ActionGirl, ActionMom...the list goes on and on.

[[folder:Card Games]]
* Niv-Mizzet (of ''TabletopGame/MagicTheGathering'''s Ravnica block; a dragon who was also a MadScientist, so you ''know'' he's dangerous, and in combination with a single card he can start an infinite damage loop)
** The whole plane of Phyrexia.

* Drax the Destroyer from Creator/MarvelComics
* Stryfe, {{clon|ingBlues}}e of ComicBook/{{Cable}}.
* Sleez, who had {{ComicBook/Superman}} and [[ComicBook/NewGods Big Barda]] star in a porno.
* [[http://www.marvunapp.com/Appendix/groteskx.htm Grotesk]]
* ComicBook/XForce villain Crule

* Hugo Drax from the ''Franchise/JamesBond'' [[Literature/{{Moonraker}} novel]] and movie ''Film/{{Moonraker}}''
* Xeno (Xenomorphs, better known as the aliens in ''Franchise/{{Alien}}'') This one might be averted by simply being proper nomenclature. "Xeno" means stranger, and it has a very strange ''morph''ology.
* Xander Drax, of ''Film/{{The Phantom|1996}}''. Who? ''"X-A-N-D-E-R D-R-A-X, Xander Drax, begins and ends with the letter X."''
* The title character of ''Film/XXx'', though at least half of that is from being played by Creator/VinDiesel.
* Drexl (from ''Film/TrueRomance'')
* Vermithrax the dragon in ''Film/{{Dragonslayer}}''

* Galbatorix from the ''Literature/InheritanceCycle'' is a name you give you child if you ''want'' him to grow up to be an evil emperor. It's ''possible'' that Galbatorix chose the name, but why is beyond most people; it doesn't roll off the tongue and sounds generically evil. You'd think someone who wanted to take over the world would ease people into it by picking something which sounded nicer. And if Galbatorix is indeed his given name, then he is fully justified in wanting to kick some ass--which raises the question of why he was let into the Dragon Riders.
* Pretty much ''everyone'' from Sanctaphrax (''Literature/TheEdgeChronicles''), but Orbix Xaxis deserves a special mention.
* Lampshaded in ''Discworld/UnseenAcademicals'' with Dr. Hix, who changed his last name's spelling from Hicks to Hix because a man with a skull ring would have to be mad, or shall we say, even madder, to pass up the chance to have an X in his name.
* Xaro Xhoan Daxos from ''Literature/ASongOfIceandFire''. While he is not really a positive character, he is not actually evil, too. In the series, however, he becomes a main antagonist by the end of the second season.
* The Ix from [[Literature/{{Dragons}} The Last Dragon Chronicles]].

[[folder:Live-Action TV]]
* T'raltixx (From ''Series/{{Farscape}}'', with a PunctuationShaker to boot)
* Xena (the [[Series/XenaWarriorPrincess Warrior Princess]]). It doesn't hurt that "Xena" can be translated as the feminine form of the (Doric) Greek word for "stranger" (would be "Xeni" in Attic or Koine Greek), therefore placing her in [[NamesToRunAwayFrom/ThePerson several]] [[NamesToRunAwayFrom/AncientDeadLanguages other]] [[NamesToRunAwayFrom/TheAdjectiveOne categories]] of NamesToRunAwayFromReallyFast.
* ''Series/TheYoungOnes'' gives us Vyvyan. You think the mere spelling of his name makes your head hurt? [[TheQuincyPunk Just wait]] [[FieryRedhead ‘til you]] [[AxCrazy meet him.]]

* Zargothrax the Dark Sorcerer of Auchtermuchty from Music/{{Gloryhammer}}. Also comes from a place unpronounceable to people not familiar with Scotland.

[[folder:Mythology and Religion]]
* And don't forget Elron's favorite, [[ChurchOfHappyology Xenu]].

[[folder:Newspaper Comics]]
* There's an archvillain named Axel in ''ComicStrip/LittleOrphanAnnie'', of all places. Besides, it almost sounds like axe.

[[folder:Tabletop Games]]
* [[ForgottenRealms Drizzt Do'Urden]]; generally a nice guy, but [[UnstoppableRage you wouldn't like him when he's angry.]]
** Jarlaxle, also of ''ForgottenRealms''. He probably won't kill you. He'll just make your life a living hell.
** Zaknafein, Drizzt's father, a four-hundred-year-old weapons master who's defeated demons in single combat and can take someone's tongue out with a whip while blindfolded. And depending on the person, enjoys doing it.
* ''{{TabletopGame/Warhammer 40000}}'': Ghazgkull Mag Uruk Thraka. An Ork over twenty feet tall. ''Run''.

* This also applies to Axel Almer in ''VideoGame/SuperRobotWars Original Generation ''2, but [[HeelFaceTurn not so in Original Generation Gaiden]], seeing that his non-[=OGs=] OG 2 personality is quite of a JerkAss, and a dangerous one at that.
* Sort of applies to Axl of ''VideoGame/MegaManX 7'', but [[TheScrappy that's to the audience only anyway]].
* All of the Organization XIII members in ''Franchise/KingdomHearts'' have names that are anagrams of their human names with an "X" added, like Lea-Axel, Braig-Xigbar, Dilan-Xaldin, etc. Xehanort follows the same pattern - among many other possibilities, his name without the X is an anagram of "no heart".
* Syn, the BigBad of ''VideoGame/CardinalSyn''.
* ''Franchise/MortalKombat'' kharacters inklude Stryker, Kobra, and Havik.
* The Snarbolax in ''VideoGame/SpiralKnights''.
* Dr. Z, BigBad [[spoiler:[[EvilerThanThou or so we are led to believe]]...]] of ''VideoGame/DinosaurKing''.
* The {{Big Bad}}s of ''VideoGame/FinalFantasyIII'', ''VideoGame/FinalFantasyIV'' and ''VideoGame/FinalFantasyV'' - Xande, Zemus and Exdeath. Subverted by Xezat in ''V'', who is in fact a legendary hero, despite having the most evil-sounding name possible.

* [[Webcomic/TheOrderOfTheStick Xykon]], self named for the Xtreme Kool Letterz quotient. Gets (more) homicidal whenever someone spells his name with a Z by mistake - [[spoiler:Zs are for pussies]]. Note the suspicious similarly of the name to the compound [[http://en.wikipedia.org/wiki/Zyklon_B Zyklon B]], used by the Nazis in death camps. Presuming this was intentional, it provides a good clue to Xykon's general nature.
* ''Webcomic/AMagicalRoommate'': X, whose birth name is Elzandra, legal name Alexandra, and happens to be a [[TheChosenOne Child of Prophecy.]] She also likes [[MadeOfExplodium explosions.]] The only reason she wouldn't qualify is her extreme apathy.

[[folder:Web Originals]]
* Dan Byker. Byker is not Biker.
* ''[[Literature/HappyAppy Forenzik.]]''

[[folder:Western Animation]]
* Vilgax (the BigBad of ''WesternAnimation/{{Ben 10}}'')
* Nebulans from the original ''{{Transformers}}'' series often have names like this. See, for example, Grax, Zarak, and Krunk.
* Thrax, the villain of ''OsmosisJones''. Presumably intended to invoke "anthrax".
* [[TropeNamer Xan]][[WesternAnimation/{{Gargoyles}} atos]]
* Pretty much everybody from [[WesternAnimation/AvatarTheLastAirbender the Fire Nation]] has a Z in their names. Zuko, Zhao, Azula, Ozai, Sozin, Azulon. Worth noting: most the Fire Nationals who don't have a Z in their names were never really antagonists, such as Iroh, Ursa, Piandao, Roku, and Jeong Jeong.
* [[WesternAnimation/CourageTheCowardlyDog Katz]].
* Kardiak, Kyd Wykkyd, and Wrex from ''WesternAnimation/TeenTitans''.
