!Allies
[[folder: Luke]]

[[WalkingTheEarth A world-trekking bounty and treasure hunter]] with a harsh demeanor and a soft heart. He [[TheRival antagonizes Lina]] to a degree, but ultimately becomes an integral ally for her during the second arc of the [[LightNovel light novels]]. He originally was an assassin, but changed his ways when Milina came into his life.

[[spoiler:Like Lei Magnus and [[AffablyEvil Rezo]], Luke holds a shard of [[BigBad Shabranigdo]] in his soul; unlike the other two, he is, at least, partially aware of Shabranigdo's presence. When Milina is killed in the second-to-last novel, his rage reaches to an extreme that allows Shabranigdo to take over, thus setting off the final battle in the final novel. Lina and Gourry eventually defeat him due to the conflict that still lied within Luke's soul.]]

----

* AllLoveIsUnrequited: Poor guy...
* {{BFS}}
* TheCameo: At the very end of the manga adaptation of ''Evolution-R.''
* DeathSeeker: [[spoiler:Luke-Shabranigdo WANTS to die.]]
* DoggedNiceGuy: To Milina
* FieryRedhead: It's revealed that he dyes his hair black because Milina doesn't like redheads.
* FirstNameBasis: No last name of his has been revealed. This is even [[LampshadedTrope lampshaded]] by Lina in the final novel.
* JerkWithAHeartOfGold
* IKnowYoureInThereSomewhereFight: [[spoiler:Like Rezo before him, Luke's human soul is still lingering when Shabranigdo is revived. There is more complication to this battle, but Luke is able to find peace, which proves to be the key to Luke-Shabranigdo's defeat.]]
* TheLancer: Replaces Zelgadis as this role in the novels. In the ''Hourglass of Falces'' manga, he's more TheBigGuy.
* MagicKnight: Wields an enchanted blade like Gourry, and is capable of casting black magic, although not to the same degree as Lina. He even has his own original spell to accomodate his sword: Ruby-Eye Blade.
* PersonOfMassDestruction
* RoaringRampageOfRevenge: [[spoiler:When Milina dies from a poisonous stab wound that went untreated due to irresponsible priests, he [[NoKillLikeOverkill ''completely obliterates'' all five shrines in the area and murders all but one of the priests.]] This continues into the final novel.]]
* RedEyesTakeWarning: Not quite, they certainly aren't [[TechnicolorEyes the nice variety]], but he isn't truly nasty either.
* TheRival
* TomatoInTheMirror: [[spoiler:Subverted, he is at least partially aware of Shabranigdo's presence within him, but doesn't try to ignore it or wholly supress him. He freely allows him to emerge when [[TearJerker Milina is killed.]] In the ''Hourglass of Falces'' manga, he even tells Milina to strike him down if Shabranigdo ever emerges from him.]]
* WalkingTheEarth
* WoobieDestroyerOfWorlds
[[/folder]]

[[folder: Milina]]

Luke's partner and fellow mercenary, she was the one who convinced him to quit his assassination job. She is well aware of the fact that he is smitten with her, and brushes off his affections constantly. [[spoiler:During a bodyguarding job in the fourteenth novel, Milina is stabbed with a poisoned knife. She is denied medical care from one man and the other does not know the spell needed to heal the toxins, and Milina dies as a result, cuing Luke's RoaringRampageOfRevenge and Shabranigdo's awakening.]]

* ActionGirl
* BareYourMidriff
* TheCameo: With Luke at the end of the ''Evolution-R'' manga.
* DeadpanSnarker
* FirstNameBasis: Also lampshaded by Lina in the final novel.
* HotterAndSexier: Her midriff-bearing ensemble is skimpified in the ''Hourglass of Falces'' manga.
* JerkWithAHeartOfGold
* KickTheDog
* KickThemWhileTheyAreDown: [[spoiler:Unintentionally caused example. She's poisoned, and the priest she was fighting against denies her care. At the next shrine, no one in the clergy knows the Resurrection spell. She then tearfully says goodbye to Luke, and [[RoaringRampageOfRevenge you can guess what happens]] from there.]]
* MagicKnight
* MoralityChain: It's because of her that Luke isn't a cold-blooded killer [[spoiler:or a PersonOfMassDestruction, for that matter]].
* SixthRanger: In ''Hourglass of Falces.''
* UnresolvedSexualTension
* WalkingTheEarth

[[folder: Sylphiel Nels Lahda]]
-> Voiced by: Creator/YumiTouma (Japanese), Stacia Crawford (English, ''Slayers'' and ''Slayers NEXT''); Creator/StephanieSheh (English, ''Slayers Revolution''), Melanie Henríquez (Latin American Spanish), Creator/MartaSainz (European Spanish)

A [[ProperLady well-mannered, gentle-natured]] shrine maiden from the city of Sairagg and the first of the party's many [[GuestStarPartyMember additional members]]; she is extremely skilled in WhiteMagic, which, unfortunately, hampers her ability in combat. She is in love with Gourry, but [[AllLoveIsUnrequited he doesn't really notice at all.]]

-----
* AllLoveIsUnrequited: Poor girl. Her love for Gourry goes right over the Jellyfish brain's head. [[spoiler: Her pain ends in the eigth novel, where she realizes that Gourry loves Lina (even though Lina herself doesn't) and, while disappointed, [[IWantMyBelovedToBeHappy accepts it and willingly gives up Gourry to her friend.]]]]
* BarrierWarrior: In addition to being an exceptional healer, she can also create strong defensive barriers.
* BewareTheNiceOnes: In ''NEXT'', she reveals that [[spoiler: she can cast Dragon Slave, just like Lina.]]
* GuestStarPartyMember: In seasons 1, 2, and 4; however, she is only this during the fight with [[CloningBlues Copy Rezo]] in the novels.
* CooldownHug: Gives one to Lina in ''NEXT'', when [[spoiler: she panicks while thinking she's killed a little girl.]]
* CripplingOverspecialization: The best in the series when it comes to white magic, but sorely lacking in terms of offense. Her first attempt at Flare Arrow (which she learned from a magazine) is pathetically weak, painfully slow, and ''[[EpicFail shaped like a carrot]]''. [[spoiler: [[TookALevelInBadass She does get better eventually]] ]].
* HimeCut: The classic "long hair and straight bangs" to fit with her lady-like personality.
* IneptMage: Sylphiel is one of the most powerful white magic users in existence, but she cannot cast black magic, with one exception: [[spoiler: after a lot of practice, she can cast a Dragon Slave that is almost as powerful as Lina's.]] But that's the only black magic spell she can pull off properly; even though she had a reasonably powerful Flare Arrow once, she seems unable to regularly cast it effectively.
* TheMedic: Her healing powers are almost ''unmatched'' in the series.
* NiceGirl: Edges out Amelia for "nicest character in the series" because she isn't WrongGenreSavvy.
* TheOjou: Her father was a high-ranked priest from Sairaag.
* ProperLady: Well-mannered, gentle-natured, modest, etc.
* PutOnABus: In the tv program, she appears as a minor ally at the climax of ''The Slayers'' and ''Slayers: Next.'' Despite promising to join the team, she's not seen for the whole of ''Try.''
** TheBusCameBack: She leads the Seiruun Nagic Squad in ''Revolution,'' and cameos in the finale of ''Evolution R.''
* ShrinkingViolet: She sharply contrasts Lina and the others in terms of extroversion.
* StatuesqueStunner: Much taller than Lina.
* TomboyAndGirlyGirl: The "girly" half, with Lina being the tomboy because she herself is a ProperLady and Lina is far too rough mannered and aggressive to fit.
* TookALevelInBadass: Happens twice in the anime. The first occurs shortly after the "[[EpicFail Flare Carrot]]" incident. A few off-screen pointers from Lina and she's easily blasting down walls with a proper Flare Arrow. For the second, see BewareTheNiceOnes above.
* WhiteMage: Even better at the art than Amelia, who usually serves as this for the party.
* WhiteMagicianGirl: A proper lady healer and love interest for the male lead.
%% Do not uncomment this unless you had more context then "fits all the traits" or "shades of this" and it can't be redundant with ProperLady. You must also add the "cultural Japanese" element; just because this is an anime doesn't mean it automatically counts.
%%%%%%*YamatoNadeshiko:
* YouGottaHaveBlueHair: Considering the blonde and red and black of the main slayers, purple is odd.

[[folder: Martina Zoana Mel Navratilova]]
-> Voiced by: Creator/TomokoIshimura (Japanese), Creator/RachaelLillis (English), Claudia Nieto (Latin American Spanish), Amelia Jara (European Spanish)

[[RichBitch The spoiled, overly-dramatic]] princess (later queen) of the kingdom of Zoana who exclusively appears in the second season of the anime (''NEXT''). She antagonizes Lina and follows her around during the course of the season because she destroyed her castle, and [[GoldfishPoopGang often falls into trouble for comedy relief.]] [[spoiler: Neverthless, she pulls herself together and gives Lina motivation to fight against [[BigBad Phibrizzo]] during the final battle, and marries the swordsman Zangulus soon after.]]

----
* BareYourMidriff:
* BunnyEarsLawyer: See {{Determinator}} below. Shows extreme competence in a lot of areas but as a villain, she's almost completely inept.
* ButtMonkey: Starting with the destruction of her kingdom she jumps from one comedic disaster to another.
* CanonForeigner: Created exclusively for ''Slayers NEXT''.
* CuteAndPsycho: More [[CloudCuckooLander garden-variety odd]] than AxeCrazy, but still... what kind of person invents their own religion?
* {{Curse}}: Black Magic-based curses are the only form of magic that she knows. She manages to cast one on Lina in an early episode: should Lina attack someone, pain would be inflicted back at her.
* {{Determinator}}: Her most defining attribute, after her insanity and solitary worship of [[SinglePreceptReligion Zoamelgustar]]. To get back on her feet after her kingdom is destroyed, she sells [[VendorTrash random trinkets]]. She takes advantage of the destruction of a kingdom to sell her religious pendants. And she ''never stops'' trying to earn money or get revenge on Lina, taking even waitressing jobs while the rest of the party is relaxing, and going all the way into another dimension with Lina to try to research how to restore her kingdom.
* {{Expy}}: She is named after a famous lesbian tennis player from the Czech Republic. Episode 16 pays a homage to this by invovling her and Lina participating in a game similar to tennis. Interestingly, Navratilova was not aware of this up until [[https://twitter.com/Toongrrl1990/status/240303727628673024 now]].
* FairytaleWeddingDress: Wears a gown worthy of a princess in the final episode [[spoiler: when she marries Zangulus.]]
* FourthDateMarriage: [[spoiler:Meets Zangulus in the 23rd episode and marries him three episodes later, having known him for what one can assume is a day or two...]]
* GoldfishPoopGang: Her role is to show up every episode or so and cause trouble for Lina.
* HappilyMarried: [[spoiler:In the final episode of ''NEXT''.]]
* HeelFaceTurn: Takes a while to get there, but happens officially when [[spoiler: Gourry is kidnapped by Hellmaster.]]
* IneffectualSympatheticVillain: She's a poor villain, and if she weren't spending so much time trying to curse people she believes responsible for her hard times, she would draw sympathy.
* TheLoad: Up until the very end she is no help to anyone. Then she [[spoiler: is the one to push Lina into unleashing the Giga Slave on Hellmaster.]]
* LoveAtFirstSight: Crushes on (chronologically) Zelgadis, Gourry, Xellos, and Zangulus at the drop of a hat, [[spoiler: and she settles down with the latter by the end of the season.]]
* MaybeMagicMaybeMundane: She worships the demon god Zoamelgustar, who nobody has ever heard of and it's strongly implied she made up herself. However, she does seemingly get a massive power boost by invoking him (for instance the curse she put on Lina is supposed to be impossible without a contract from a mazoku) and Hellmaster at one point claims he's sparing her out of respect for her patron in a way that leaves it ambiguous if he's joking.
* NoCelebritiesWereHarmed: Martina is a famous lesbian tennis player from the Czech Republic
* NoblewomansLaugh: Often laughs in this style when hatching a (in her mind) devious plan.
* NotSoDifferent: It's remarked that she and Lina have more in common than they'd like to acknowledge at the end of episode 16.
* OddFriendship: When traveling with the main group, she actually comes to get along best with Amelia, possibly since they're both princesses. Amelia even [[spoiler: happily attends and cheers on Martina's wedding to Zangulus at the end.]]
* OjouRinglets: Again, a mark of her former high social standing is her curling hair.
* PluckyComicRelief: She's not a serious threat and everyone except her knows it. She's there to provide comedy instead of drama, [[spoiler: with the exception of during the confrontation with Hellmaster.]]
* PrincessInRags: She's the princess of Zoana, and forced to sell VendorTrash for food.
* RichBitch: A formerly rich princess who believes everyone beneath her (except Xelloss for some reason).
* RoyalsWhoActuallyDoSomething: Averted until the very end, where she toughens up and tries to motivate Lina when [[spoiler:Gourry is kidnapped and {{Brainwashed}} by Phibrizzo. ''And succeeds''.]]
* RunningGag: She is always being left behind by the core party, and complains about it. It takes on a darker aspect in the final episode [[spoiler: where they fly off chasing Gourry and leave her and Zangulus stranded on a rapidly-disintegrating pinnacle of rock, surviving only thanks to Martina's comic relief status.]]
* SerialRomeo: In NEXT she falls madly in love with a different male cast member every appearance.
* SpoiledBrat: Her dad did a poor job raising her.
* TalkingToHimself: An in-universe example: she worships a diety she more or less made up herself, and praises herself using "his" voice.
* UnderwearOfPower: Wears what appears to be a pair of yellow panties over her leggings.
* YouGottaHaveBlueHair: Few other humans in this series have green hair.

[[folder: Prince Philionel El Di Seyruun]]
-> Voiced by: Masahiro Anzai (Japanese, ''Slayers'' and ''Slayers NEXT''), Creator/MinoruInaba (Japanese, ''Slayers TRY'' and ''Slayers Revolution''), Matt Black (English, ''Slayers'' ep. 11-13), Creator/JimmyZoppi (English, ''Slayers'' ep. 25-26, ''Slayers NEXT'' and ''Slayers TRY''), David Brimmer (English, ''Slayers Revolution''), Daniel Jiménez (Latin American Spanish), Enrique J. Lles (European Spanish)

The Regent of the Kingdom of Seyruun [[note]] (elaborated in the light novels: as the current king is stricken with illness, Phil more or less runs the country)[[/note]], heir to the throne, and father of Amelia [[spoiler:and Naga]]. Despite the turmoil that follows being heir, Phil is resilient and incredibly just, both towards his subjects and towards Lina and her allies. Along with those, his two other notable traits are his [[{{Gonk}} boorish, dwarf-like]] appearance and his physical prowess.
----

* BadassMoustache: A fine handlebar style.
* BadassNormal: Unlike his daughter, he lacks white magic and shamanism. Regardless, he is able to stand against lesser demons with his own raw strength.
* BadassPacifist: He's a weird case. On one hand he gets rampaging ghosts to listen to him with words alone. One the other hand, he ''does'' use physical violence which a typical BadassPacifist would avoid and calls his techniques oxymoronic names like "Pacifist Crush" and "Goodwill To All Men Smash".It actually might be that this very mindset is what helps him put down lesser demons, since they are [[FridgeBrilliance explicitely vulnerable to positive emotions]].
* BareFistedMonk: All his techniques are bare handed and they resemble wrestling moves.
* BigDamnHeroes: Subverted in his attempt to save the group near the end of the first season. While he did manage to save the heroes for the moment by causing a distraction (and changing the tone to a more comedic one that made character deaths unlikely, as is lampshaded by the heroes), he was completely out of his league against the villain.
* BoisterousBruiser: A big and hammy man that can crush you with his bare hands.
* CallingYourAttacks: "PACIFIST CRUSH!"
* FakingTheDead: [[spoiler:Does this in ''NEXT'' after Alfred's botched assasination attempt on him.]]
* GenerationXerox: Averted. It's pointed out on a few occasions that he and Amelia really don't look anything alike, whenever people find out they're father and daughter.
* LargeHam: In addition to CallingYourAttacks he's also a passionate LoveFreak.
* LoveFreak: Like Father like Daughter. All his attacks have this theme.
* NiceGuy: Overall, despite his LargeHam tendencies, he's a pretty friendly, easygoing, helpful guy. It's easy to see where Amelia gets it from.
* NoblewomansLaugh: Not with the same dignified tone as the trope suggests, but he is prone to laughing a lot.
* PapaWolf: To Amelia ''and'' his kingdom.
* RoyalsWhoActuallyDoSomething: This is another trait Amelia gets from him; active and heroic royal service.
* TechnicalPacifist: Despite his attacks, he's never killed anyone because he's a pacifist at heart.
* TheWisePrince: Despite being a LoveFreak, he doesn't overdo it or fall to WrongGenreSavvy like his daughter.

!The Mazoku Lords and their Followers
[[folder: Ruby-Eye Shabranigdo]]
->Voiced by: Creator/DaisukeGori (Japanese), Roger Kay (English, ''Slayers''), Creator/MarcThompson (English, ''Slayers Evolution-R''), Oscar Zuloaga (Latin American Spanish), Enrique J. Lles (European Spanish)

The source of evil in the ''Slayers'' world, and one of the four dark lords of the four worlds created by [[GuardianOfTheMultiverse The Lord of Nightmares]]. Many millenia prior to the series proper, he was defeated and split into seven pieces by [[{{God}} Flare Dragon Ciefeed]], and those pieces were subsquently sealed away into the bodies of seven humans, with Ciefeed's intent being that they would be purged [[WeAreAsMayflies quickly due to their short lifespans.]] Unfortunately, this was not the case, as extreme amounts of hatred can force these pieces to reawaken.

So far, three carriers of Shabranigdo have been revealed; two have been destroyed for good (Rezo and [[spoiler:Luke]], with the latter only having been done in the novels) and one was sealed away a thousand years before the series begins (Lei Magnus). The other four carriers are unknown. Shabranigdo is also a potent source of the world's BlackMagic.

----
* AstonishinglyAppropriateAppearance
* BigRedDevil: In the anime and games. His two appearances in the novels are bizarrely different in appearance.
* BlackMagic: Two incredibly powerful spells ([[FantasticNuke the Dragon Slave]] and Ruby-Eye Blade) draw power from him. As a result the only Black Mage spell that can even affect him is drawn from The Lord Of Nightmares and has a very real chance of burning the world in the process.
* DarkIsEvil: His skin is a very dark shade of red, and all of his appearances across the franchise take place in very grim settings, such as a tall tower in the first novel, or in the ruins of Taforashia in the fifth season of the anime.
* EvilMakesYouUgly: In the first novel.
* EvilPlan: All the mazoku lords are (in theory) working on his plan: destroy the world.
* EvilOverlord: Rules over the Mazoku.
* FinalBoss: In the fifth season of the anime.
* GodOfEvil: He is literally the source of all supernatural evil in the Slayers Universe, and possibly all ''mundane'' evil as well, given he predates the human race by a wide margin. All monsters in the Slayers Universe were created roughly one thousand years before the series begins during the War of Dark Lord's Resurrection by his Lei Magnus-Shabranigdo incarnation.
* GracefulLoser: The Rezo incarnation salutes Lina (and Rezo's rebellious spirit) for their victory with his dying breath.
* GreaterScopeVillain: The boss of the Mazoku lords and ultimate evil, but his parts are either sealed away or missing or dead so he doesn't actually do much himself.
* HijackedByGanon: Takes over Rezo's position as the DiscOneFinalBoss in the first novel/first anime season after Rezo awakens him. [[spoiler:He does so again in ''Evolution-R'', since his spirit also being inside the Hellmaster's Jar is explained as the source of the corruption that led to Gioconda's greed, Duclis's fixation on vengeance, Zuuma's madness, and even Rezo's selfishness that led him to do anything to see, even if only for one last time after being resurrected in Posel's body.]]
* OrcusOnHisThrone: Justified in regards to the fact that he's a being [[SealedEvilInACan that was sealed away in pieces]], but he dawdles quite a bit when he awakens out of Rezo's body.
* PartlyCloudyWithAChanceOfDeath
* ThePowerOfHate: Is powered by this. [[spoiler:During the final battle in ''Evolution-R'', he explains to Lina that he was able to cling to Rezo's soul while sealed in the [[SoulJar Hellmaster's Jar]] because of the fear and hatred he grew of her during his first battle with her.]]
* RedEyesTakeWarning
* SealedEvilInACan: [[spoiler:He's sealed alongside Rezo in the Hellmaster's Jar in ''Evolution-R'', and only Xellos is aware of it.]]
* SealedInsideAPersonShapedCan: Seven "cans", even.
* ShapeshifterIdentityCrisis: [[spoiler:Luke's incarnation of Shabranigdo suffers from this ''big time.'' He despises humans for killing Milina, but still loves her, and hates his fellow Mazoku for setting off the incident in the thirteenth novel. He ultimately decides to give Lina and Gourry a large portion of power and give them a fair chance of beating him, and his love for Milina ultimately allows him to die by his own power.]]
* TailorMadePrison: The sorcerer Lei Magnus's incarnation of Shabranigdo was sealed away (along with Lei Magnus himself) in a block of ice in the [[GrimUpNorth Kaltaart Mountains]]. A game on the UsefulNotes/SuperFamicom had both sorcerer and demon as the TrueFinalBoss.
[[/folder]]

[[folder: Hellmaster Phibrizzo]]
->Voiced by: Creator/KazueIkura (Japanese), Creator/WayneGrayson (English), Ivette Harting (Latin American Spanish), Amelia Jara (European Spanish)

Considered to be the strongest of Shabranigdo's five generals, Phibrizzo is [[TheGrimReaper the manipulator of human souls and can control life and death at the drop of a hat.]] He is the main antagonist of the eighth novel and of the second season of the anime. His beast form is an amorphous black sphere.

[[NietzscheWannabe A sadistic and manipulative]] being who [[DeathSeeker thrives on murder]], he is able to defeat fellow general [[TheBrute Chaos Dragon Gaav]] with a snap of his fingers, and this sets off his sadistic plan that culminates into the climax of season two. [[spoiler:His plan was to provoke Lina to destroy the world by casting the all-mighty [[FantasticNuke Giga Slave]]; he succeeds in doing so by killing off her friends one by one. Unfortunately for him, the Giga Slave is miscast, and the Lord of Nightmares is summoned. Unamused by his actions, she obliterates him from existence.]]

----
* AFormYouAreComfortableWith: The form of a child.
* AxCrazy: [[spoiler:Though it isn't evident until [[VillainousBreakdown the climax]]]].
* BeCarefulWhatYouWishFor: [[spoiler:He craved for destruction... so this is what Lord of Nightmares granted him (and him only) when she was inadvertently summoned]].
* TheBigBad: Of ''King of the City of Ghosts'', ''Slayers NEXT'' and the last volumes of ''Slayers: Super-Explosive Demon Story''.
* TheChessmaster: And ''how''. [[spoiler:He had been manipulating everybody -- heroes and villains alike -- for most of ''Slayers NEXT'', siccing Gaav on Lina Inverse and assuming that she will use the Giga Slave spell against him. When that failed, he quickly came up with a backup plan to use Lina's friends as hostages and blackmail her into casting that spell]].
* CreepyChild: His human form is in the likeness of an androgynous young boy, which easily fools Lina and the others.
* CrystalPrison: He seems fond of imprisoning others with these.
* DeathSeeker: His ultimate goal is to more or less blow up the world-and himself-in a spectacular fashion. [[spoiler:He gets (part of) his wish when he provokes the Lord of Nightmares in the final episode.]]
* DidntSeeThatComing: [[spoiler:The intervention of the Lord of Nightmares]].
* DidYouJustPunchOutCthulhu: Phibrizzo, did you just nuke Gaav by snapping your fingers?
* TheDragon: Of Shabranigdu, as his most powerful general.
* DudeLooksLikeALady: Or a little girl, complete with big eyes and long eyelashes. In the manga iteration covering his storyline this is actually taken further where part of the plot is that he explicitly took control of the body of a little girl named Erina to make Lina let her guard down around him.
* EvilerThanThou: Gaav and his minions are the primary antagonists for most of ''Slayers NEXT'' and it would seem that Gaav himself is going to be set up as Lina's [[VillainOfTheWeek ultimate adversary of the season]]. [[spoiler:However, once Phibrizzo reveals himself, he instantly proves to be a far greater threat. Not only it turns out he's been manipulating both sides the whole time, but the moment he takes off the mask, he ''[[WorfEffect instantly annihilates]]'' Gaav with a ''snap of his fingers'', taking his place as a BigBad with the much more sinister goal of destroying not only Lina Inverse, but also [[OmnicidalManiac everyone and everything else]]]].
* TheFakeCutie: His human form is extremely adorable, when not pulling freakish {{Slasher Smile}}s. [[InvokedTrope He mentions in one episode that he did this on purpose because he knew no one would suspect him if he took the form of a cute little kid]].
* GoneHorriblyRight: [[spoiler:He wanted to force Lina to call upon the power of the Lord of Nightmares. She ended up summoning the Lord of Nightmares ''herself'']].
* TheGrimReaper: He is able to control human life and death.
* HoistByHisOwnPetard: [[spoiler:His elaborate plan to force Lina into a desperate enough situation to try and cast the Giga Slave again actually worked perfectly. Unfortunately its success didn't mean what he thought it did, as it turns out the Lord of Nightmares' power is inseparable from her physical presence and attention, meaning when the spell is cast, you're technically summoning her briefly into the physical universe. When she possesses Lina, Phibrizzo [[VillainousBreakdown completely loses his marbles]], realizing that all his plans and designs that he worked on for years were ruined in an instant just when they were so close to fruition. In a fit of desperation (and insanity), he tries to destroy Lina's physical form, reasoning that Lord of Nightmares' power is trapped within it and this would mean "releasing" her. Of course, this turns out to be a bad idea. Phibrizzo's attack doesn't harm her in the slightest and she kills him off-handedly in retaliation.]]
* LightIsNotGood: His true form pretty much invokes the trope.
* LaughingMad:
* NietzscheWannabe: [[spoiler:He wants to destroy everyone and everything, seeing it as the ultimate goal of the Mazoku race]].
* {{Sadist}}: [[spoiler:He revels in his victims’ suffering and despair, as evidenced when he kills all of Lina Inverse’s friends one by one.]]
* SpellMyNameWithAnS: His name was romanized as "Phibrizzo" in the Central Park Media subtitles.
* SphereOfDestruction: His true form is what appears to be an amorphous black sphere.
* ThanatosGambit: Subverted; instead of having something come later, he wanted to die [[GoOutWithABang spectacularly]] along with the rest of the world.
* VileVillainSaccharineShow: He is notably one of the most sadistic, depraved and vile characters in the series. But, he's evenly more terrifying.
* VillainousBreakdown: [[spoiler:Once he realizes that [[GoneHorriblyRight the Giga Slave spell has summoned the Lord of Nightmares herself]] and his elaborate plan with years in the making has just gone to hell, his smug demeanor drops instantly and he goes [[SanitySlippage completely off the rails]]]].
* YouGottaHaveBlueHair: His human form's hair.
* YourSoulIsMine: He can destroy souls and subsequently kill others by crushing what appear to be little glass spheres -- the physical representation of them. He [[DisneyDeath kills]] Amelia, Sylphiel, Zelgadis, Zangulus, and Martina in this fashion.
[[/folder]]

[[folder: Chaos Dragon Gaav]]
->Voiced by: Creator/JojiNakata (Japanese), Creator/DanGreen (English), Creator/RubenLeon (Latin American Spanish)

[[TheBrute The most aggressive of the five generals]]. He was sealed into his human form by Aqualord Ragradia, who hoped that his power would diminish overtime, similar to Shabranigdo's dilemma. However, Gaav's soul fused with the soul of his human host, and because of it, he [[CoolPeopleRebelAgainstAuthority has rebelled against his fellow lords out of the desire to survive]]. He is the main antagonist of the seventh novel and the DiscOneFinalBoss of ''NEXT.'' His true form is a three-headed red dragon.

Gaav spends most of the early novels/second season spreading his influence towards the humans with the help of his underlings, hoping to [[LaResistance secure power and raise a powerful human army.]] It is revealed in the novels that he is doing this in order to [[spoiler:destroy [[PiecesOfGod the piece of Shabranigdo]] sealed in the Kaltaart Mountains]]. Because of his rebellious nature, Hellmaster Phibrizzo murders him during a fight with Lina's party.

----
* AFormYouAreComfortableWith: Averted. Since he's sealed into a human form that really is what he looks like.
* AmbiguouslyBrown: His human form.
* BadassLongcoat: Wears one in human form.
* {{BFS}}: Wields a massive sword that is powerful enough to severely injure the normally NighInvulnerable Zelgadis.
* CurbStompBattle: Easily pummels the two boys in the party; it isn't until Lina strikes him with the Ragna Blade that he gets hurt. He survives anyway.
* CoolPeopleRebelAgainstAuthority: Strangely Justified: because he gained something of a human consciousness when he was sealed into the body of one, a survival instinct not normally associated with the Monster race took over, thus making him no longer able to fight for the goal of [[KillEmAll eliminating all existence.]]
* EnemyCivilWar: Had a brief scuffle with the other lords due to the trope above.
* EvilRedhead: A red haired antagonist.
* ImpaledWithExtremePrejudice: [[spoiler:Hellmaster checks him out in this fashion in the novels; in the anime he disintegrates slowly instead.]]
* LargeHam: He's pretty boisterous.
* MyGreatestSecondChance: He is the one who gave [[WoobieDestroyerOfWorlds Val]], the [[LastOfHisKind final ancient dragon]], a portion of his powers along with a reason to live again.
* OurDragonsAreDifferent: His true form.
* RapunzelHair: Has long hair.
* TheReasonYouSuckSpeech: Gives a short but harrowing one to Amelia about her black-and-white obsession with justice, then proceeds to try to kill her until Zelgadis saves her with a DivingSave.
* WhatMeasureIsANonHuman: Normally he would KillEmAll, but his time as a human made him gain human survival instincts. Most of this trope is disregarded, though, because he still desires to overrun the world chaotically.

[[folder: Kanzel]]
->Voiced by: Creator/IsseiFutamata (Japanese), Nathan Price (English), Moisés Ramos (Latin American Spanish), Enrique J. Lles (European Spanish)

A mazoku serving under Gaav who attempted to assassinate Prince Philionel in the fourth book. In truth he is actually hoping to lure out and assassinate Lina Inverse.

----
* DiscOneFinalBoss: He's portrayed as a major threat in the first half of ''NEXT'', but only lasts up to its halfway point.
* ThoseTwoBadGuys: With Mazenda in the anime.

Originally a follower of Greater Beast Zelas Metallium and later a servant of Chaos Dragon Gaav, he is a menacing cloaked figure that hides a manifestation in the physical world. He first appears framing Damia and Tarimu by summoning ooze monsters out of their estates, and he makes an alliance with Halcyform. However, when confronted by Xellos, he retreats without a fight. He later attacks Lina in the temple of the Claire Bible manuscript, revealing that he was granted enough of Gaav's power to withstand a Dragon Slave.

----
* CoolMask: Wears a white stone mask under his cloaks, which is actually his Pledge Stone.
* LightningBruiser: Already incredibly fast and tough for a low-ranking Mazoku, he gains even more resistance thanks to Gaav.

[[folder: Dynast Grausherra]]

[[SmugSnake The tactical, scheming, and ever elusive]] master of disguise among the five generals. He uses all of these trades in order to cause destruction, and he hopes to start a second war between [[BlackAndWhiteMorality the Shinzoku and the Mazoku]], along with the intention to [[spoiler:resurrect the piece of Shabranigdo in Luke]]. He is the main antagonist of the thirteenth novel. His true form is what appears to be a golem-like beast wearing spiky armor.

Dynast sends his general [[ActionGirl Sherra]] to hinder Lina and Gourry, and when she is defeated, he sets off the conflict in the thirteenth novel by impersonating the king of the kingdom of Gairia. Lina is able to defeat him by encasing him in Zanaffar Armor and striking him down with the Ragna Blade. [[NotQuiteDead The main part of his body on the astral plane remains intact, thus ensuring his survival,]] but he is otherwise severely wounded to the point that he can no longer manifest on the physical plane. He has not appeared in the anime or any other media.

----
* AFormYouAreComfortableWith: He can take human form.
* DeathTrap: Lina is able to render his powers useless by trapping him into a set of magic-nullifying Zanaffar Armor, and cuts him down from there.
* EvilGenius: Since both Hellmaster and Chaos Dragon are dead, he is forced to fit into this role despite being closer to TheBrute. [[spoiler:Even his plan to resurrect the soul of Shabranigdo is an attempt at copying what Hellmaster did several millennia ago.]]
* HeWhoMustNotBeSeen: Has no definitive human form.
* MasterOfDisguise: He impersonates a king.
* WordOfGod: Dynast has had at least four different priests and generals made in his lifetime; Zelas only has Xellos, and the other three lords each have one priest and one general.

[[folder: Deep Sea Dolphin]]

Dolphin resides in the sea that lies to the southeast of the mainland the story takes place in most of the time. In terms of goals and backstory, there is little known about her; however, it's hinted that Dolphin herself was the one to have planned her priest [[TheChessmaster Huraker's]] scheme to [[spoiler:seize the power of Aqualord Ragradia]] in the ''Knight of the Aqualord'' manga. Her true form is unknown.

Dolpin appears alongside Zelas in the final novel and traps Lina and Gourry into the sub-space where [[spoiler:Luke-Shabranigdo]] awaited them.

----
* AFormYouAreComfortableWith: Her human form.
* EvilPlan: Believed to have started it in the ''Knight of the Aqualord'' manga, where [[spoiler:she sent Huraker off and cause all of that turmoil in order to have Lina gain the power of one of the four Shinzoku lords; from there Huraker would absorb both Lina's and Lyos' powers in order to become [[AGodAmI a demon with the power of the gods.]] Yikes...]]

!Other Villains
[[folder: Rezo the Red Priest]]
->Voiced by: Creator/TakehitoKoyasu (Japanese), Charles Rolfe (English, ''Slayers''), Creator/LiamOBrien (English, ''Slayers Revolution'' and ''Evolution-R''), José Manuel Vieira (Latin American Spanish), Enrique J. Lles (European Spanish)

A [[VillainWithGoodPublicity highly well-known and respected]] priest and sorcerer, and Zelgadis' great-grandfather. He is known across the kingdoms of the Old World for performing miraculous feats with magic, namely healing. However, this is mostly a cover-up for his more shadowy intentions, which is finding a method of opening his blind eyes in any way possible. [[spoiler:His eyes are permanently blind because a shard of [[BigBad Shabranigdo]] is sealed within him, and his eyes act as something of a seal. He never considered this possibility until he broke that seal and released Shabranigdo.]]

Rezo served as the catalyst for many events in the series. He is the first major antagonist that Lina fights, and he returns later in the anime where the group learns that he was involved in the sealing of a kingdom ([[spoiler:it's also subtly implied that he caused the plague that forced the kingdom to be sealed away in the first place]]), and more of his less pleasant side is revealed.

----
* BadassBookworm
* BlindSeer
* BlueAndOrangeMorality: He [[TheChessmaster arranges matters]] so that not only does his soul survive his death in the Hellmaster's Jar, not only does he need to be resurrected in order to restore the people of Taforashia, but he ensures Lina and the others will be there when it happens...so that after getting to see light and the world one last time, they can destroy him [[spoiler:and Shabranigdo]] again. Because he has faith they can do it.
* ColorCodedForYourConvenience: His red robes. The novels elaborate on the fact that many high-ranking sorcerers that graduate from magical guilds are assigned a color as a part of their title (an example would be Tarim and Daymia, who, in the novels, are Tarim the Violet and Daymia the Blue respectively. There is also Lina's infamous color, pink.).
* CrazyPrepared: (Anime only) He ''invented'' his own magical jar for his soul to hide in if he ever dies, all for the sake of continuing to find a way to open his eyes...
* DeathEqualsRedemption: Somewhat. The first time, his soul is able to hold back [[spoiler:Shabranigdo]] long enough for Lina to strike the killing blow against the BigBad. The second time he not only tries to hold him back again, as he is finally slain for good [[spoiler:he is able to cast Posel's soul back into his chimera body, saving him from the Giga Slave]].
* EvilSorcerer
* HijackedByGanon: To a lesser extent, since [[spoiler:he himself is being corrupted/manipulated by Shabranigdo]], but it is revealed in ''Evolution-R'' that he was not only the one who created Ozzel, but ordered her to protect the Hellmaster's Jar and bring about his resurrection, which is how she and the jar ended up in the possession of Gioconda and Duclis, thus influencing their inner darkness.
* IncestIsRelative: Averted. He was thought to be both two ''and'' three generations removed from Zelgadis, courtesy of a blurb in the English dub. He's old to the point that Zelgadis can no longer pinpoint the generation gap. WordOfGod put out that they're three generations (great-grandfather) removed.
* LiteralGenie: Well, he ''did'' say that Zelgadis would be transformed when he promised him power.
* MeaningfulName / BilingualBonus: His name means "prayer" in Spanish.
* OlderThanTheyLook: He's stated to be about a hundred years old, but looks at least half that - the only true indicator of his older age are two bony lines under his eyes. When Lina meets him in the novels, she describes him as looking "young and old at the same time.
* SealedInsideAPersonShapedCan: [[spoiler:He is the person-shaped can.]]
* StartOfDarkness: Rezo's inability to cure his own blindness despite being able to do in other people slowly pushed him into taking more desperate measures and eventually became an obsession. [[spoiler:This allowed the shard of [[BigBad Shabranigdo]] sealed within his eyes to corrupt his soul, culminating on the demon taking over him.]]
* SquishyWizard
* VillainWithGoodPublicity: He's known to virtually everyone on the continent, and both Lina and Amelia revere him as such (until TheReveal, obviously).
* YouGottaHaveBlueHair: He has purple hair.

->Voiced by: Creator/KazuhiroNakata (Japanese), Nathan Price (English), Renzo Jiménez (Latin American Spanish)

* SoulJar: He has made a Pledge of Immortality with Seigram - so long as Seigram's mask remains intact, he can't die.
* {{Telepathy}}: Displays this in the novel.

[[/folder]]

[[folder: Copy Rezo]]
->Voiced by: Creator/TakehitoKoyasu (Japanese), Peter Davis (English), José Manuel Vieira (Latin American Spanish)

A copy created by the Red Priest for use in his experiments to cure his blindness. Copy Rezo's only desire is to surpass the original, even if the world might be destroyed in the process. He is the BigBad of the second arc of the first season/the third novel.

* BetaTestBaddie: A clone of the villainous Rezo.
* BodyHorror: [[spoiler: Due to being fused with a mazoku. In the anime, he has two mouths on the palms of his hands, which allow him to cast spells quicker. In the novel, these two extra mouths are where his eyes should be.]]
* CloningBlues: He is ''so'' insecure about being a clone that he will do absolutely anything to surpass the original.
* EyesAlwaysShut: Either when pretending to be the real Rezo (anime) or [[spoiler:due to having mouths there instead]] (novel).
* MyGodWhatHaveIDone: In the anime, his death scene is treated as such a moment, when he seems to understand and regret the death and destruction he's caused, and asks only to be buried beneath Flagoon. In the novel, there's no such moment of clarity, and he passes away as bitter as he's always been.
* YouHaveOutlivedYourUsefulness: Kills Eris once she has filled her purpose. Even the original Rezo wasn't quite that cruel.
* WhamShot: He’s a copy, but after killing off Eris, Copy Rezo casually removes the control gem from his forehead before crushing it, showing that he’s fully sentient.
[[/folder]]

[[folder: Erisiel Vrumugun]]
-> Voiced by: Etsuko Ishikawa (Japanese), Rachel Nanstad (English), Rossana Cicconi (Latin American Spanish)

Eris is a sorceress who accompanied Rezo on his journeys and fell in love with him. He eventually left her in his search for a way to open his eyes. After learning of his death, she sought revenge on Lina using Copy Rezo.

* AllLoveIsUnrequited
* AvengingTheVillain: Her goal.
* BloodFromTheMouth: During her death.
* EvilCostumeSwitch
* IgnoredEnamoredUnderling
* MisplacedRetribution: Eris tries to kill Lina and her group for causing Rezo’s death, when in actuality, he was killed once Rezo removed the seal on his eyes [[spoiler: which released the shard of Shabranigdo sealed in himself]], so if anything, the Slayers group were technically trying to prevent Rezo’s death. Zelgadis even calls Eris out on it, simply saying “totally misplaced resentment”.
* PeoplePuppets: She is able to control people by attaching gems to their forehead.
* SpikesOfVillainy
* VillainousBreakdown: Eris was in complete shock when Copy Rezo shot her in the back, unable to process why he would do that to her.
* YouHaveOutlivedYourUsefulness: She is shot in the back by Copy Rezo once he is done with her.

[[folder: Zanaffar]]
->Voiced by: Creator/KoujiIshii (Japanese), Creator/DanGreen (English)

An immensely powerful beast with near-complete immunity to magic. It was originally armour created using the Claire Bible to fight the Mazoku, but due to a flaw in the process, it became sentient, consuming its wearer and going out of control (the flawless, safe version is called a Zenefa). One of these creatures laid waste to Sairagg before it was slain by a previous wielder of the Sword of Light and sealed under the Holy Tree Flagoon. In the anime, it was unsealed by Copy Rezo who merged with it to increase his power to fight Lina. Another Zanaffar was born during the events of ''Revolution'' after [[spoiler: Duclis activates Gioconda's armor]] and goes on a rampage.

* AGodAmI: The Zanaffar from ''Revolution''.
* AchillesHeel: The Sword of Light.
* BreathWeapon
* CannibalismSuperpower: It acquires the knowledge of those it consumes.
* TheCorruption: Its armour form does this to its wearer, eventually consuming them.
* NoSell: Due to being sealed off from the astral side, most spells are useless against it (except magic using the power of the Lord of Nightmares).
* SealedEvilInACan: The one sealed under Flagoon.
[[/folder]]

[[folder: Duclis]]
->Voiced by: Takashi Matsuyama (Japanese), Scott Rayow (English)

A human-gray tiger chimera who is an antagonist in the fifth light novel and the main antagonist in ''Revolution''. In the novels, he is a guard for the Cult of Shabranigdo, having being rescued by their leader after being betrayed by his comrades. In the anime, he is a former friend of Pokota who wants revenge against everyone who he believes turned a blind eye to the suffering of their homeland, Taforashia.

* BigDamnHeroes: Has such a moment in the finale of ''Revolution'' after changing sides, when his resistance to Zanaffar's absorption and a very timely attack provides the distraction to let Lina finish using the Ragna Blade and Dragon Slave.
* EmergencyTransformation: In the novel.
* HalfHumanHybrid: A chimera in the novel. In the anime, it is an artificial body.
* HeelFaceTurn: If of the last-minute variety, in the anime.
* IOweYouMyLife: His reason for serving the Cult of Shabranigdo in the novel.
* KillEmAll: His goal in the anime.
* KillMeNowOrForeverStayYourHand: Asks this of Pokota in the anime; refused out of love, although to him living is actually a punishment.
* MyGodWhatHaveIDone: Has a quiet moment of this as he's dying and being transformed by his Zanaffar armor, when he finally [[DyingAsYourself comes back to himself]].
* MyRevengeIsMercy: Not from Pokota, who can't bring himself to kill his friend, but Phil in the anime, who agrees he will live but will have to remain trapped in his tauric chimera form, apart from people, [[WalkingTheWorld traveling the wilderness]] completely alone, haunted by the guilt over those he had killed.
* SparedByTheAdaptation: Lives in the anime, dies in the novel.
* WellIntentionedExtremist: His initial motivation in the anime, aside from seeking a cure for his people and a way to break Rezo's spell, is to punish those neighboring countries who left his kingdom to die without aid, something which inspires great sympathy even if his methods leave a lot to be desired. However, as time goes on he [[JumpingOffTheSlipperySlope becomes more and more unhinged]] (possibly [[TheCorruption encouraged by his Zanaffar armor]], although Shabranigdo also claims it was due to the influence of his spirit [[spoiler:in the Hellmaster's Jar]]). Even once he finds out [[spoiler:aid was indeed sent but it had been intercepted by Gioconda]], he ''still'' desires {{Revenge}} on the countries he believed failed his people and their honor. As a result he unleashes Zanaffar to punish them and make them suffer as his people had, claiming that whether they survived or not was up to fate and would prove their true worth.

[[folder: Gioconda]]
->Voiced by: Gara Takashima (Japanese), Fiona Jones (English)

A marquess of the kingdom of Ruvinagald whom Duclis is working with. She intends to learn how to mass-produce the Zanaffar armour and also sells the magic tanks produced on the way for money. [[spoiler: She is also responsible for diverting the aid that was being sent to Taforashia.]]

* AdaptationalLateAppearance: In the original novels he first appeared during Kanzel's attack on Seyruun, which occurs in the second season of the anime. He doesn't appear until the anime's fourth season.
* AnArmAndALeg: [[spoiler: He loses both of his arms in battle with Lina and Gourry, and has to merge with a Mazoku to gain new ones. He later loses ''those'' arms as well.]]
* CastingAShadow
* CruelAndUnusualDeath: [[spoiler:Courtesy of cone!Xellos impaling and then quite literally obliterating his body.]]
* OffingTheOffspring: [[spoiler:In the anime.]]
* ProfessionalKiller
* SanitySlippage: He gradually becomes more and more unhinged, to the point that he [[spoiler:murders his own son]]. According to Shabranigdo, this is due to his use of the Hellmaster's Jar [[spoiler:to join with Mazoku, since this also exposed him to the corruption of the Demon Lord's spirit]].
* WarForFunAndProfit: More or less why he's an assassin in the novels; the anime adds a revenge factor for [[spoiler:the death of his wife during an imprisonment; it probably would not have happened if his father paid the ransom the kidnappers demanded in the first place.]]

!Other Characters
[[folder: The Lord of Nightmares]]

"''She who shines like gold upon the Sea of Chaos''", the supreme creator goddess of the ''Slayers'' universe. Despite the name, and the homage the Mazoku pay to her, she mostly doesn't get involved in things. She shows up in the afterwords of the novels/manga as "Author's Official Spokeswoman L", much to the annoyance of the author himself, [[RageAgainstTheAuthor who finds himself on the receiving end of her abuse]].

* AboveGoodAndEvil: In Xellos's own words, she has a very capricious nature to begin with. And she's y'know... God...
* BlueAndOrangeMorality: Can be called neither good nor evil, and does things on her whims. She killed Phibrizzo without a second thought even though he worshipped her. She was touched by Lina's reasons for summoning her and so spares her friends, but is fully intending to abscond with her body. And then when Gourry's devotion to Lina has him following her into the realm of the Gods she decides to give Lina back her body after all.
* DemonicPossession: A very rare benevolent case in this instance. She does this to Lina after she 'dies' while invoking the Giga Slave. To honor Lina's final thoughts, she obliterates Phibrizzo with every intention of taking Lina's body for her own purposes.
* DissonantSerenity: Even when Phibrizzo, the strongest of Ruby Eye's subordinates, fired off a full-powered energy attack to try and destroy her vessel, she didn't even bat an eye as she blocked it.
* EldritchAbomination: Her 'body' is what Lina's world, and three others, are made of.
* GodOfChaos: Her title as the will and mind of the [[PrimordialChaos Sea of Chaos]]. She's every bit as chaotic as her title implies.
* GuardianOfTheMultiverse: She created four worlds, put in a god and devil in each one and if called upon can undo anything in any of those worlds that she sees fit to.
* NamesToRunAwayFromReallyFast: Any ranked Mazoku and Dragon knows about the Lord of Nightmares as she is the one who created them all.
* TheOmnipotent: There is nothing in all the worlds that can harm her, while she can, with a thought, unmake anything and anyone in any of them.
* SheIsTheKing: Despite her masculine title, is referred to as female.
* WildMagic: The source of power for Lina's Giga Slave and Ragna Blade. To date, Lina is the only one who has survived wielding it. The Giga Slave especially has the potential to destroy a good chunk of the world if it gets out of control.

[[folder: Luna Inverse]]

Luna Inverse is Lina's "ever-persevering, never-appearing" older sister. She is TheChosenOne, a Knight of Ceipheed who wields the Dragon God's power, but prefers staying in her hometown as a waitress. Lina fears her greatly.

* AlwaysSomeoneBetter: The rare sort of mage that is more powerful than Lina.

* TheGhost: She never appears in the story proper.
%%* HeroOfAnotherStory
* InformedAbility: Her magical power is apparently equal to the Dragon God's though we've never seen her so much as appear in person let alone use magic.
* LazyBum: "Lazy" might be too strong of a word since she does make a living as a waitress. But as much of a JerkAss as Lina can be towards her own friends and random civilians, she at least puts forth the effort into heroics and saving the world, sometimes at Luna's forced insistence. Luna puts in absolutely no effort in these matters despite having the power to do so and just delegates all the work to her younger sister.
* StoryBreakerPower: She would probably make quick work of the series' villains, if she ever showed up.

He is the main antagonist of the thirteenth novel. His true form is what appears to be a golem-like beast wearing spiky armor.

Dynast sends his general [[ActionGirl Sherra]] to hinder Lina and Gourry, and when she is defeated, he sets off the conflict in the thirteenth novel by impersonating the king of the kingdom of Gairia. Lina is able to defeat him by encasing him in Zanaffar Armor and striking him down with the Ragna Blade. [[NotQuiteDead The main part of his body on the astral plane remains intact, thus ensuring his survival,]] but he is otherwise severely wounded to the point that he can no longer manifest on the physical plane.

* HeWhoMustNotBeSeen: Has no definitive human form.
* MasterOfDisguise: He impersonates a king.
* WordOfGod: Dynast has had at least four different priests and generals made in his lifetime; Zelas only has Xellos, and the other three lords each have one priest and one general.

[[folder: Deep Sea Dolphin]]

Dolphin resides in the sea that lies to the southeast of the mainland the story takes place in most of the time. In terms of goals and backstory, there is little known about her; however, it's hinted that Dolphin herself was the one to have planned her priest [[TheChessmaster Huraker's]] scheme to [[spoiler:seize the power of Aqualord Ragradia]] in the ''Knight of the Aqualord'' manga. Her true form is unknown.

Dolpin appears alongside Zelas in the final novel and traps Lina and Gourry into the sub-space where [[spoiler:Luke-Shabranigdo]] awaited them.

* EvilPlan: Believed to have started it in the ''Knight of the Aqualord'' manga, where [[spoiler:she sent Huraker off and cause all of that turmoil in order to have Lina gain the power of one of the four Shinzoku lords; from there Huraker would absorb both Lina's and Lyos' powers in order to become [[AGodAmI a demon with the power of the gods.]] Yikes...]]
* TheDarkChick: Of the Mazoku Lords.
* TheGhost: Only appeared in the novels, and has no definitive beast form.
* PimpedOutDress: Wears a poofy dress covered in pearls in her human form.
* TechnicolorEyes: Her eyes in her human form are abnormally shiny...
* TomboyAndGirlyGirl: The "girly" half, with Zelas as the tomboy.
* WaterIsWomanly: The Mazoku Lord over water and the seas is a feminine, beautiful woman with long dark blue hair.

!Other Villains
[[folder: Rezo the Red Priest]]
->Voiced by: Creator/TakehitoKoyasu (Japanese), Charles Rolfe (English, ''Slayers''), Creator/LiamOBrien (English, ''Slayers Revolution'' and ''Evolution-R''), José Manuel Vieira (Latin American Spanish), Enrique J. Lles (European Spanish)

A [[VillainWithGoodPublicity highly well-known and respected]] priest and sorcerer, and Zelgadis' great-grandfather. He is known across the kingdoms of the Old World for performing miraculous feats with magic, namely healing. However, this is mostly a cover-up for his more shadowy intentions, which is finding a method of opening his blind eyes in any way possible. [[spoiler:His eyes are permanently blind because a shard of [[BigBad Shabranigdo]] is sealed within him, and his eyes act as something of a seal. He never considered this possibility until he broke that seal and released Shabranigdo.]]

Rezo served as the catalyst for many events in the series. He is the first major antagonist that Lina fights, and he returns later in the anime where the group learns that he was involved in the sealing of a kingdom ([[spoiler:it's also subtly implied that he caused the plague that forced the kingdom to be sealed away in the first place]]), and more of his less pleasant side is revealed.

* BadassBookworm
* BlindSeer
* ColorCodedForYourConvenience: His red robes. The novels elaborate on the fact that many high-ranking sorcerers that graduate from magical guilds are assigned a color as a part of their title (an example would be Tarim and Daymia, who, in the novels, are Tarim the Violet and Daymia the Blue respectively. There is also Lina's infamous color, pink.).
* CrazyPrepared: (Anime only) He ''invented'' his own magical jar for his soul to hide in if he ever dies, all for the sake of continuing to find a way to open his eyes...
* EvilSorcerer
* IncestIsRelative: Averted. He was thought to be both two ''and'' three generations removed from Zelgadis, courtesy of a blurb in the English dub. He's old to the point that Zelgadis can no longer pinpoint the generation gap. WordOfGod put out that they're three generations (great-grandfather) removed.
* LiteralGenie: Well, he ''did'' say that Zelgadis would be transformed when he promised him power.
* MeaningfulName / BilingualBonus: His name means "prayer" in Spanish.
* OlderThanTheyLook: He's stated to be about a hundred years old, but looks at least half that - the only true indicator of his older age are two bony lines under his eyes. When Lina meets him in the novels, she describes him as looking "young and old at the same time."
* SealedInsideAPersonShapedCan: [[spoiler:He is the person-shaped can.]]
* StartOfDarkness: Rezo's inability to cure his own blindness despite being able to do in other people slowly pushed him into taking more desperate measures and eventually became an obsession. [[spoiler:This allowed the shard of [[BigBad Shabranigdo]] sealed within his eyes to corrupt his soul, culminating on the demon taking over him.]]
* SquishyWizard
* VillainWithGoodPublicity: He's known to virtually everyone on the continent, and both Lina and Amelia revere him as such (until TheReveal, obviously).
* YouGottaHaveBlueHair: He has purple hair.

[[folder: Halcyform the White]]
->Voiced by: Creator/KazuhiroNakata (Japanese), Nathan Price (English), Renzo Jiménez (Latin American Spanish)

The chairman of the Atlas City Sorcerer's Guild who seeks immortality. He is the BigBad of the second light novel and in the first part of ''NEXT''.

* GoOutWithASmile: In the novel after [[spoiler: being stabbed by Rubia]].
* ImmortalityImmorality: Abducted human subjects for his research.
* LoveMakesYouEvil: In the anime.
* PlayingWithFire: He appears to specialise in shamanic fire spells.
* {{Necromantic}}: In the anime.
* RapidAging: In the anime, after the Pledge Stone is destroyed.
* SealedEvilInACan: At the start of the novel since Tarim and Daymia were unable to kill him.
* SoulJar: He has made a Pledge of Immortality with Seigram - so long as Seigram's mask remains intact, he can't die.
* {{Telepathy}}: Displays this in the novel.
* TogetherInDeath: [[spoiler:With Rubia in the anime.]]

[[folder: Copy Rezo]]
->Voiced by: Creator/TakehitoKoyasu (Japanese), Peter Davis (English), José Manuel Vieira (Latin American Spanish)

A copy created by the Red Priest for use in his experiments to cure his blindness. Copy Rezo's only desire is to surpass the original, even if the world might be destroyed in the process. He is the BigBad of the second arc of the first season/the third novel.

* BetaTestBaddie: A clone of the villainous Rezo.
* BodyHorror: [[spoiler: Due to being fused with a mazoku. In the anime, he has two mouths on the palms of his hands, which allow him to cast spells quicker. In the novel, these two extra mouths are where his eyes should be.]]
* CloningBlues: He is ''so'' insecure about being a clone that he will do absolutely anything to surpass the original.
* EyesAlwaysShut: Either when pretending to be the real Rezo (anime) or [[spoiler:due to having mouths there instead]] (novel).
* MyGodWhatHaveIDone: In the anime, his death scene is treated as such a moment, when he seems to understand and regret the death and destruction he's caused, and asks only to be buried beneath Flagoon. In the novel, there's no such moment of clarity, and he passes away as bitter as he's always been.
* YouHaveOutlivedYourUsefulness: Kills Eris once she has filled her purpose. Even the original Rezo wasn't quite that cruel.
* WhamShot: He’s a copy, but after killing off Eris, Copy Rezo casually removes the control gem from his forehead before crushing it, showing that he’s fully sentient.

[[folder: Erisiel Vrumugun]]
-> Voiced by: Etsuko Ishikawa (Japanese), Rachel Nanstad (English), Rossana Cicconi (Latin American Spanish)

Eris is a sorceress who accompanied Rezo on his journeys and fell in love with him. He eventually left her in his search for a way to open his eyes. After learning of his death, she sought revenge on Lina using Copy Rezo.

* AllLoveIsUnrequited
* AvengingTheVillain: Her goal.
* BloodFromTheMouth: During her death.
* EvilCostumeSwitch
* IgnoredEnamoredUnderling
* MisplacedRetribution: Eris tries to kill Lina and her group for causing Rezo’s death, when in actuality, he was killed once Rezo removed the seal on his eyes [[spoiler: which released the shard of Shabranigdo sealed in himself]], so if anything, the Slayers group were technically trying to prevent Rezo’s death. Zelgadis even calls Eris out on it, simply saying “totally misplaced resentment”.
* PeoplePuppets: She is able to control people by attaching gems to their forehead.
* SpikesOfVillainy
* VillainousBreakdown: Eris was in complete shock when Copy Rezo shot her in the back, unable to process why he would do that to her.
* YouHaveOutlivedYourUsefulness: She is shot in the back by Copy Rezo once he is done with her.

[[folder: Zanaffar]]
->Voiced by: Creator/KoujiIshii (Japanese), Creator/DanGreen (English)

An immensely powerful beast with near-complete immunity to magic. It was originally armour created using the Claire Bible to fight the Mazoku, but due to a flaw in the process, it became sentient, consuming its wearer and going out of control (the flawless, safe version is called a Zenefa). One of these creatures laid waste to Sairagg before it was slain by a previous wielder of the Sword of Light and sealed under the Holy Tree Flagoon. In the anime, it was unsealed by Copy Rezo who merged with it to increase his power to fight Lina. Another Zanaffar was born during the events of ''Revolution'' after [[spoiler: Duclis activates Gioconda's armor]] and goes on a rampage.

* AGodAmI: The Zanaffar from ''Revolution''.
* AchillesHeel: The Sword of Light.
* BreathWeapon
* CannibalismSuperpower: It acquires the knowledge of those it consumes.
* TheCorruption: Its armour form does this to its wearer, eventually consuming them.
* NoSell: Due to being sealed off from the astral side, most spells are useless against it (except magic using the power of the Lord of Nightmares).
* SealedEvilInACan: The one sealed under Flagoon.

* RedEyesTakeAlert: The eyes of this thoroughly nasty guy are just red lights behind his mask.

* LazyBum: Incredibly lazy to the point of making her little sister do all of the world saving for her.

* CrazyPrepared: (anime only) He ''invented'' his own magical jar for his soul to hide in if he ever dies, all for the sake of continuing to find a way to open his eyes...

* SealedInsideAPersonShapedCan
* StartOfDarkness: Rezo's inability to cure his own blindness despite being able to do in other people slowly pushed him into taking more desperate measures and eventually became an obsession. [[spoiler:This allowed the shard of [[BigBad Shabranigdo]] sealed within his eyes to corrupt his soul, culminating on the demon taking over him]].

* EyesAlwaysShut: Either when pretending to be the real Rezo (anime) or [[spoiler: due to having mouths there instead]] (novel).

* TheChessmaster: And ''how''. [[spoiler:He had been manipulating everybody -- heroes and villains alike -- for most of the ''Slayers NEXT'', siccing Gaav on Lina Inverse and assuming that she will use Giga Slave spell against him. When that failed, he quickly came up with a backup plan to use Lina's friends as hostages and blackmail her into casting that spell]].

* DeathSeeker: His ultimate goal is to more or less blow up the world-and himself-in a spectacular fashion. [[spoiler:He gets his wish when he provokes the Lord of Nightmares in the final episode.]]

* EvilerThanThou: Gaav and his minions are the primary antagonists for most of the ''Slayers NEXT'' and it would seem that Gaav himself is going to be set up as Lina's [[VillainOfTheWeek ultimate adversary of the season]]. [[spoiler:However, once Phibrizzo reveals himself, he instantly proves to be a far greater threat. Not only it turns out he's been manipulating both sides the whole time, but the moment he takes off the mask, he ''[[WorfEffect instantly annihilates]]'' Gaav with a ''snap of his fingers'', taking his place as a BigBad with much more sinister goal of destroying not only Lina Inverse, but also [[OmnicidalManiac everyone and everything else]]]].

* NietzscheWannabe: [[spoiler:He wants to destroy everyone and everything, seeing it as the ultimate goal of Mazoku race]].

* VillainousBreakdown: [[spoiler:Once he realizes that [[GoneHorriblyRight Giga Slave spell summoned the Lord of Nightmares herself]] and his elaborate plan with years in the making has just gone to hell, his smug demeanor drops instantly and he goes [[SanitySlippage completely off the rails]]]].

* YourSoulIsMine: He can destroy souls and subsquently kill others by crushing what appear to be little glass spheres -- the physical representation of them. He [[DisneyDeath kills]] Amelia, Sylphiel, Zelgadis, Zangulus, and Martina in this fashion.

* CoolPeopleRebelAgainstAuthority: Strangely Justified: because he gained something of a human conciousness when he was sealed into the body of one, a survival instinct not normally associated with the Monster race took over, thus making him no longer able to fight for the goal of [[KillEmAll eliminating all existence.]]

* LargeHam
* MyGreatestSecondChance: He is the one who gave [[WoobieDestroyerOfWorlds Val]], the [[LastOfHisKind final ancient dragon]], a portion of his powers and gave him a reason to live again.

* AboveGoodAndEvil: In Xellos's own words, she has a very capricious nature to begin with. And she's y'know...God...

* EldritchAbomination: Her 'body' is what Lina's world, and three others, are made up of.
