[[quoteright:174:https://static.tvtropes.org/pmwiki/pub/images/4pacx.png]]
[[caption-width-right:174:]]
-->''Voiced by'': Creator/RobinAtkinDownes

Mumm-Ra was the ancient foe of the [=ThunderCats=], long ago defeated. Resurfacing, Mumm-Ra masterminded Thundera's downfall to obtain the Eye of Thundera, the jewel within the Sword of Omens' hilt.
----
!!Tropes associated with Mumm-Ra:
* AdaptationalBadass: The original's sedentary {{Mummy}} playing OrcusOnHisThrone isn't in evidence here. SquishyWizard he may be, but Mumm-Ra makes his debut with an impressive act of regicide, followed up with the [[OneHitKill slaughter]] of Claudus' PraetorianGuard, all without breaking a sweat ''or'' breaking out the OneWingedAngel.
* AdaptationalVillainy: Downplayed. His pet from the original show Ma-Mutt doesn't exist in this continuity, so he has no PetTheDog moments. As we also get his backstory, he's committed a lot more atrocities than his original self.
* AdaptationalWimp: The original version never has a weakness to sunlight and can walk around at the day time, in contrast to this version.
* AdaptiveArmor: [[spoiler:Using [[PowerCrystal Power Crystals]] as [[AmplifierArtifact Amplifier Artifacts]], his Gauntlet can transform into a set of custom skeletal armor.]]
* AgonyBeam: In his OneWingedAngel form, he employs this on Lion-O with intent to kill.
* AncientEvil: He is thousands of years old and the main antagonist of the series.
* ArchEnemy: He serves as the legendary enemy of the [=ThunderCats=], but none hate him more than Lion-o for killing his father. Mumm-ra, by comparison, despises Lion-o for being the descendent of Leo, who betrayed him and caused his original defeat.
* BadBoss: He doesn't show any regard for the lives of his underlings. In flashbacks he was shown have a strict rule by fear policy with his army with only the Tiger clan, stated to be his favored soldiers, were loyal to him. The cats he treated with some respect, and everyone else he kept in check with explosives attached to them. He still considers the lizards to be nothing more than cannon fodder, and when faced with issue of desertions, he brings in Atticus and Kaynar.
* BatPeople: Mumm-Ra is a batlike humanoid complete with leaf-nosed snout, and gains bat wings in his OneWingedAngel form.
%%* BecauseDestinySaysSo: His response to Leo trying to [[spoiler:talk him out of destroying the Plundaar solar system, even though Leo points out that he could a destroy a star that wouldn't wipe any inhabited planets]].%%... is?
* BigBad: Of the series, much as he was in the original.
* BreathWeapon: In his OneWingedAngel form, Mumm-Ra can breathe hot pink PureEnergy energy blasts.
* BrokenPedestal: Mumm-Ra became this for [[spoiler:his tactician Leo]] in the backstory when he [[spoiler:destroyed a solar system populated by billions to forge the Sword of Plundaar.]] This was what convinced [[spoiler:Leo that Mumm-Ra had to be stopped.]]
* ByThePowerOfGrayskull: (Villain variant) "Ancient Spirits of Evil, transform this decayed form into Mumm-Ra, THE EVERRRR-LIIIVIIIIING!!!" triggers Mumm-Ra's TransformationSequence into his secondary OneWingedAngel form.
* CardCarryingVillain: [[InvokedTrope Invoked]] in a very literal sense, as Mumm-Ra must call upon "Ancient Spirits of Evil" to grant him access to his OneWingedAngel Form.
* CommandingCoolness: Pre-{{Gotterdammerung}}, Mumm-Ra was [[spoiler:the Commander of a SpaceNavy that took the Eye of Thundera as {{Plunder}}, and counted ''[=ThunderCats=]'' among his underlings.]]
* CoolSword[=/=]DoubleWeapon: His [[spoiler:Sword of Plun-Darr]]
* TheCorrupter: Mumm-Ra shows some signs of this. He manages to use Grune's ambition and paranoia to make him betray the Cats, and he uses the Lizards' hatred of the Cats to recruit them into his army. While in the Astral Plains, Mumm-Ra is also able to manipulate Lion-O and Tygra into fighting each other using the memory of a childhood accident. [[spoiler: And in the finale it's revealed Mumm-Ra used a dying Pumyra's hatred of Lion-O for supposedly abandoning her to make her work for him as TheMole.]]
* CreepyCrows: [[spoiler:Mumm-Ra's desperation form, which he uses either to flee after coming too close to defeat at the hands of the [=ThunderCats=], or for stealth purposes.]]
* DarkIsEvil: Though Mumm-Ra himself is colored grey, his [[TankGoodness tank]] and any weaponry or armor he uses are black, and chased with TronLines. Though, for some bizarre reason, he does refer to his sword in light terms, such as "lighting the way" (literally, as it ''does'' light the way for him to find it).
* DemonicPossession: When summoning the dragon in the {{Necromancer}} entry below, he infuses the creature with his soul in order to control it.
* TheDreaded: Even as an artifact of history, his reputation precedes him. His first spoken line, wherein he [[BadassBoast refers to himself]] completely without irony as being "[a thing] of your worst nightmares," suggests he is perfectly happy to [[ExploitedTrope exploit]] this.
* EvenEvilHasStandards: When describing Addicus and Kanar to Slithe, he says the two have committed crimes even he wouldn't do. [[SubvertedTrope Of course, he then sends Slithe to hire them, anyway... ]]
* EvilBrit: On an alien planet, no less.
* EvilCannotComprehendGood: [[spoiler: Thinks nothing of Leo and Panthera's shock that he would wipe out billions of lives in a galaxy just to create a sword.]] He mocks Lion-O for trying to save Pumyra rather than try to escape with the Sword of Plun-Darr:
-->'''Mumm-Ra:''' "Generations pass, and still your species is weakened by emotion!"
* EvilIsHammy: He's at his hammiest when he does his incantation to become Mumm-Ra the Ever-Living.
* EvilOldFolks: Not only is he Really700YearsOld, he looks it.
* FangsAreEvil: He has fangs and he's the main villain.
* FantasticRacism: Somewhat subtle, but when in pursuit of the Sword of Plundarr, he informs Slithe that it's a job "too important to leave in the hands of animals." It's a bit more obvious in the flashback. [[spoiler:He "praises" Leo in a way that shows contempt for the Cats as a whole and treats the Lizards as expendable cannon fodder.]]
* FauxAffablyEvil: He seems to enjoy putting on more refined airs that simply emphasize his brutal nature. It's especially noticeable in "Birth Of the Blades"
-->'''Pumyra:''' Run! Don't let him get the Sword of Omens too!
-->'''Mumm-Ra''': ''[[ElectricTorture (zaps her)]]'' Quiet, my dear. We're ''talking.''
* HumanoidAbomination: Peculiarly, Mumm-Ra resembles nothing so much as an inexplicably red-eyed, fanged, snub-nosed, grey [[HumansAreCthulhu human]] in {{Mummy}} wrappings. [[spoiler:However, his OneWingedAngel form explains the snub nose and makes his species explicit: He's a leaf-nosed (Vampire) [[BatOutOfHell bat]].]] The artists get bonus points for just having his Mummy form move in a subtly WRONG way.
* {{Hypocrite}}: In "Birth of the Blades", he goes on and on about emotion being a weakness, but he becomes downright furious when Lion-O taunts him with his resemblance to Leo, the one who defeated the ancient sorcerer long ago.
* InTheHood: Mumm-Ra always wears a long, trailing, tattered red cloak with the hood concealing much of his face. [[OneWingedAngel At least until he transforms...]]
* KamehameHadoken: Quite capably uses a variation of this in the premiere to kill most of the Clerics in [[OneHitKill a single blow]].
* KnightOfCerebus: Whenever he shows up, things get serious.
* LargeAndInCharge: In his OneWingedAngel form, he ''towers'' over the Cats.
* LivingRelic: Mumm-Ra has been around for a ''very'' long time. [[spoiler:He predates the colonization of Third Earth.]]
* TheMagnificent: The '''EVER-LIVING!'''
* TheManBehindTheCurtain: [[SubvertedTrope Subverted.]] TheDreaded ancient enemy of the [=ThunderCats=] is a small, stooped, old, emaciated... red-eyed EvilSorcerer and ''HumanoidAbomination.'' His physical frailty only serves to make him more disturbing. And then he transforms, and the [=ThunderCats=] [[CurbStompBattle get their tails handed to them]].
* MasterOfIllusion: We first see him use it to [[spoiler: disguise himself as Panthro.]]
* MeaningfulName: Derived from the English word "mummy," and ''Ra'' the ancient Egyptian ''sun'' god.
%%* MightMakesRight: What Mumm-Ra believes in.%%Is?
* MindRape: The interrogation variety is one of Mumm-Ra's specialties, [[spoiler: Though Jaga screams, he doesn't yield the information Mumm-Ra seeks.]].
* MiniatureSeniorCitizen[=/=]MisterBig: In his ShapeshifterDefaultForm, Mumm-Ra is quite short and stooped, but no less intimidating.
* MobileMenace: Gets around in a [[TankGoodness tank]], the Storm Charger, when it suits him.
* {{Mummy}}: With all the standard trappings, and some decidedly nonstandard, like a techno-pyramid.
* {{Necromancer}}: Uses the ashes of an ancient dragon monster to return it to life in "Recipe for Disaster." [[spoiler:He also revived Pumyra to act as his agent.]]
* NemesisWeapon: [[spoiler:The Sword of Plun-Darr, as witnessed in "Legacy". And, as the counterpart to the Sword of Omens, it, too, can shrink down to fit inside his own Gauntlet. [[ShapeShifterWeapon Oh, and it can extend from a single-bladed sword to a double-bladed one.]] Unlike the Sword of Omens, the Sword of Plun-Darr has considerable power even without a Warstone in its hilt.]]
* NinjaPirateZombieRobot: Mumm-Ra is a *deep breath* {{mummy}}[=/=][[OurLichesAreDifferent lich]] [[spoiler:vampire bat ''alien from space''.]] Who lives in a pyramid [[spoiler:''spaceship'']] and rides around in a tank [[spoiler:that's a coffin]]. Amazing, no?
** Later, in "Recipe for Disaster," he uses the ashes of the long-dead Dragon of Sycorax to [[BackFromTheDead summon the monster]]... as part of a ritual to [[DemonicPossession take over its body]] and use it to fight the [=ThunderCats=].
* OurLichesAreDifferent: His concept also borrows heavily from Lich iconography.
* OmnicidalManiac: [[spoiler:He destroyed an entire galaxy, with three planets populated by billions of people, to create the material that would become the Sword of Plun-Darr and its gauntlet.]]
* OneWingedAngel: Appropriately enough, [[WingedHumanoid has wings]]. [[spoiler:Gets a massive upgrade when he incorporates the Tech Stone into the Gauntlet of Plun-Darr.]]
* OutsideContextProblem: Became this over the centuries as memory of him faded away into legend and superstition.
* RedEyesTakeWarning: Played absolutely straight, even [[LiteralMetaphor literally]], as his first appearance ''is'' his eyes, seen in a [[{{seers}} vision]] sent by the Sword of Omens.
* SadisticChoice: When he fights Lion-O in the Mountain of Plun-Darr to retrieve the sword of the same name, he threatens Pumyra by throwing her into a chasm, forcing Lion-O to choose: Grab the Sword of Plun-Darr before Mumm-Ra can, or rescue his fellow cat?
* SealedEvilInACan: Complete with creepy CompellingVoice and a commanding [[spoiler:"''Release me!''"]]
* ShapeshifterDefaultForm: A slight-framed HumanoidAbomination in {{Mummy}}-wrappings and a large cloak.
* SkeletonsInTheCoatCloset: His AdaptiveArmor has a skeletal motif.
* SorcerousOverlord: An EvilSorceror and an EvilOverlord
* SquishyWizard: [[SubvertedTrope Only]] in his ShapeshifterDefaultForm. Beware when he busts out his ByThePowerOfGreyskull.
* SufficientlyAdvancedAlien: Otherworldly magic powers have to come from ''somewhere''...
%%* TakeOverTheWorld: But of course!
* TankGoodness: His Storm Charger [[spoiler:made of the face of his sarcophagus]]
* TentacleRope: He can use his bandages to ensnare an opponent and lift them clear off of the ground.
* TransformationNameAnnouncement: "Ancient Spirits of Evil... [[TransformationSequence transform]] this decayed form, into Mumm-Ra... '''THE EVERRRR-LIIIVIIIIING'''"
* TransformationSequence: Mumm-Ra's [[OneWingedAngel Ever-living]] transformation sequence, triggered by his ByThePowerOfGreyskull, is seen rather infrequently.
* VaderBreath: Is exceptionally wheezy, [[spoiler: especially when he first wakes up.]]
* VoluntaryShapeshifting: Has a ShapeshifterDefaultForm, a OneWingedAngel form, general MasterOfDisguise[=/=]MasterOfIllusion powers, and a desperation form for quick escapes.
* [[spoiler:WeakenedByTheLight: In "Omens Part 2", sunlight interrupts him as he begins of his TransformationSequence and singes him a bit before he staggers back indoors.]]
** In "Journey to the Tower of Omens" [[spoiler:Mumm-Ra is forced to flee after Jaga's HeroicSacrifice via a powerful light spell, and Mumm-Ra ''was already in his true form when it happened''.]]
** Later, in "Birth of the Blades," Mumm-Ra [[spoiler: gets his hands on the Sword of Plundarr after Lion-O chooses to save Pumyra, at the cost of giving Mumm-Ra the chance to grab the sword]]. Just as he's about to press his advantage, cracks in the walls of the cave they were fighting in start allowing sunlight through. [[spoiler: Seeing this, Mumm-Ra decides to retreat for the time being.]]
* WouldHurtAChild: "Do you think I would hesitate to destroy two kittens?"
* YouAreACreditToYourRace: Seems to have had this opinion of [[spoiler:Leo, and the cats in general, back when they served him prior to the crash-landing on Third Earth. He was even willing to give them a planet of their own to live on once he'd conquered the universe... supervised by him, of course.]]
* YourSizeMayVary: The size of his OneWingedAngel is ''very'' inconsistent. Compared Lion-O, it's usually a few feet taller than him, but in one point during his fight with Leo in "Legacy" (who was the same size as Lion-O) he's only a head taller, and in "Birth of the Blades", we have a scene where Leo only comes up to his waist.

[[folder:Grune]]
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/032-ThunderCats-2011-Grune-the-Betrayer_2797.jpg]]
-->''Voiced by'': Creator/ClancyBrown

Grune is one of Claudus' trusted generals, sent with Panthro to find the Book of Omens. However, motivated by his ambition for power, Grune allied himself with the Lizards and Mumm-Ra.
----
!!Tropes associated with Grune:
* TwentyFourHourArmor: The only time he takes off his armor is to swap it for a new set.
%%* ArchEnemy: To Panthro.
* AdaptationalAttractiveness: While not a {{Bishonen}} like the series' protagonists, he's certainly more handsome in this version.
* AmbitionIsEvil: Grune's motivation for his FaceHeelTurn, underscored repeatedly during Panthro's {{Flashback}}s.
-->'''Panthro''', ''after Grune expresses a desire to rule Thundera'': [[FantasticCasteSystem You planning on becoming a lion]]?\\
'''Grune''': No, I'm planning on becoming ''[[TheUsurper king]]''.
* AscendedExtra: Was a minor, though [[EnsembleDarkhorse popular]], villain in the original series, only appearing in a couple episodes. This version is Mumm-Ra's [[TheDragon right-hand man]].
* AsskickingLeadsToLeadership: He may run from fights he can't win, but the ones he ''has'' won include killing a giant spider many times his size.
* BearerOfBadNews: With a [[HeDidntMakeIt headshake]], and melancholic praise for his skill in battle, Grune [[DeathNotification informs Claudus of Panthro's death]] and hands over Panthro's [[TragicKeepsake nunchucks]].
* TheCaptain: As with Panthro, a [[DownplayedTrope Downplayed]] element of his {{backstory}}, seen as a stepping stone on his way to becoming a general.
* CarryABigStick: A big freaking mace [[note]]which appears to be a Japanese [[http://en.wikipedia.org/wiki/Kanab%C5%8D kanabo]].[[/note]] that turns into a [[{{BFG}} big freaking]] LightningGun. Had a more traditional round-headed mace before his FaceHeelTurn.
* CavalryBetrayal: During TheSiege of Thundera, Grune shows up to fire a FlareGun [[spoiler:that seems to bring the HumongousMecha fleet to a halt]], only to perform an InsigniaRipOffRitual and an EvilCostumeSwitch while debuting his nasty new weapon.
* ChangingClothesIsAFreeAction: Even given his FlungClothing, it takes entirely too little time for him to change into his more elaborate togs.
* ChronicBackstabbingDisorder: He betrays Thundera to Mumm-Ra and later plan to betray Mumm-Ra himself.
* LesCollaborateurs: Formed an alliance with Mumm-Ra and the Lizards to orchestrate Thundera's fall.
* ContrivedCoincidence: If it wasn't for him and Panthro's [[spoiler:pointless]] quest for the Book of Omens, the duo wouldn't have ran into Mumm-Ra's ship. This allows Mumm-Ra to influence Grune into freeing him.
* DealWithTheDevil: Frustrated in his ambitions of rulership, Grune frees Mumm-Ra in exchange for the promise of power, agreeing to engineer Thundera's sacking and serve as TheDragon until Mumm-Ra gets ahold of the Eye of Thundera. He is, however, quick to recognize possible opportunities to betray Mumm-Ra.
* DevilInPlainSight: He dropped anvil-sized hints to Panthro for years upon years that he had designs on the throne. But for some reason, it didn't register [[spoiler: until the moment they met Mumm-Ra.]]
* TheDragon: He serves as Mumm-Ra's second-in-command up until the end of the first arc.
* DudeWheresMyRespect: Part of his GlorySeeker behavior. He prefers large shows of courage instead of working under the radar, and hopes to become General of Thundera's troops. He's initially very unhappy with being given the quest to find the Book of Omens, and in a moment of paranoia, insists to Panthro that not only is it a SnipeHunt, but a UriahGambit to get Grune out of the kingdom.
* EvilCostumeSwitch: By way of revealing his alliance with the Lizards, Grune changes into a dark suit of metallic armor.
* EvilFormerFriend: To both Claudus and Panthro, rather than Jaga in the original series.
* EvilSoundsDeep: Comes with being voiced by Creator/ClancyBrown.
* FaceHeelTurn: He betrayed the Thundercats to side with Mumm-Ra.
* FangsAreEvil: Because his single, massive sabertooth is neither little nor cute.
* FashionableAsymmetry: Thanks to having only one protruding fang on one side of his mouth. It ''does'' look pretty cool though.
* FlungClothing: Grune casts aside his armor in this way.
* FourStarBadass: Once "Thundera's greatest general"
* GlorySeeker: Calculatingly so, as glory is a means to acquire power.
* GodEmperor: Grune seeks to [[ExploitedTrope exploit]] the CargoCult of the Book of Omens this way
--> '''Panthro''': Look at them, they're already hailing us as heroes.
-->'''Grune''': If we come back with the Book of Omens, we'll be hailed as ''gods''.
* GrievousHarmWithABody: His ''own'' body, in this case. In "Between Brothers", Panthro reveals the reason he's only got one fang: in the past they were confronted by a legendary giant spider, and Grune ''ripped his tooth out'' so he could stab it in the eye.
* HeroicBuild: As Panthro notes, he's a cat "who pulls his weight."
* HeterosexualLifePartners: With Panthro, in {{Flashback}}s. Likes him enough that even after his FaceHeelTurn he readily makes the offer that WeCanRuleTogether.
* [[{{Hammerspace}} Hyperspace Mace]]: In {{flashback}}. Grune's mace appears out of nowhere in time for him to fight Panthro
* IDidWhatIHadToDo: As explained by Panthro, his personal philosophy is "To defeat an enemy, any sacrifice is worth it." [[spoiler:This comes back to bites him in the ass when Panthro throws his own philosophy back at him, sacrificing his own arms in order to throw Grune into a collapsing Astral Plane.]]
* IFightForTheStrongestSide: [[InvertedTrope Inverted.]] Grune gives this as his baseline motivation, but the reality is that [[ItsAllAboutMe he'll join whichever side promises HIM more power]].
* InsigniaRipOffRitual: Grune reveals his CavalryBetrayal and begins his EvilCostumeSwitch this way.
* {{Jerkass}}: Betrayed his friend, betrayed his king, betrayed his people, will only fight battles where he's guaranteed to win...and that's just the beginning of this list.
* LetNoCrisisGoToWaste: Grune's M.O. as a soldier. There's a war on? Enlist so he can put his skills to use. He sees his King overrun by Lizards? Rig a catapult to kill them al - well, not the King - so he can become a Captain thanks to his timely demonstration of valor. Huge battle? Keep count of his kills so he can make General.
* LifeOrLimbDecision: The story of Grune's tooth can be considered one.
* MorphWeapon: His aforementioned ''[[CarryABigStick kanabo]]'' can be adjusted so that it telescopes into multiple sections, revealing a high-voltage interior that charges up to turn the weapon into a {{BFG}} LightningGun.
* MythologyGag[=/=]WholeCostumeReference: Before putting on his battle armor, he's wearing a tweaked version of his outfit from the original series.
* NeverFoundTheBody: [[spoiler:In "Between Brothers", he gets sucked into the collapsing Astral Plane along with Panthro's arms; time will tell whether or not he's been KilledOffForReal]].
* OddNameOut: Along with Claudus, breaks the standard ADogNamedDog convention for Thundercat names.
* TheParagonAlwaysRebels: [[DeconstructedTrope Deconstructed]] with Grune, who understands the surest way to succeed at rebellion is to ''become'' a paragon.
* RedRightHand: His single fang, a clear deformity that gives him a decidedly sinister appearance despite his AdaptationalAttractiveness.
* SmugSnake: Much like his original incarnation. He's one of Mumm-Ra's most dangerous lieutenants, but he's got a bad habit of underestimating his enemies.
* SparedByTheAdaptation: Unlike his 80's counterpart, he isn't a ghost in this series.
** [[spoiler: ...Unless [[NiceJobBreakingItHero Panthro throwing him into the astral plane]] was meant as {{Foreshadowing}}.]]
* TheStarscream: Began plotting to kill Mumm-Ra prior to [[spoiler:his final battle with Panthro. Given that he was last seen being flung into a dimensional gateway, nothing really came of it.]]
* {{Turncoat}}: Defected to Mumm-Ra as soon as he was promised power.
* TheUsurper: Initially planned to use his status as Paragon and later discoverer of the Book of Omens to become this, apparently including Panthro in his plans.
** [[spoiler: In "Between Brothers," it's revealed that he's willing to usurp Mumm-Ra's position of authority, as well.]]
* WithUsOrAgainstUs: The moment Panthro refuses to join him in [[spoiler:defecting to Mumm-Ra's side]], Grune declares him an enemy and attacks.

[[folder:Slithe]]
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/ThunderCats-Slithe_5353.jpg]]
-->''Voiced by'': Creator/DeeBradleyBaker

The brutish leader of the Lizards, Slithe is slightly lacking in sophistication, but he's very intuitive and cunning. He's also a very cruel and vindictive warchief, and will sacrifice anyone in pursuit of his goals.
----
!!Tropes associated with Slithe:
* AdaptationalBadass: By far smarter and more dangerous than his 80's counterpart.
* FantasticRacism: Harbors a strong hatred for cats.
* FatBastard: He's very portly and one of Mumm-Ra's lieutenants.
* FreudianExcuse: [[WhatCouldHaveBeen had the series gone on]], more light would have been shed on Slithe's motivations. He was driven by grieving fury over the loss of his family to the Cats.
* {{Jerkass}}: He's extremely unpleasant and cares little about the lives he ends.
* LargeAndInCharge: Bigger than the lizard {{Mooks}}, though not as big as Grune or Mumm-Ra's OneWingedAngel.
* MookLieutenant: Despite being a General, serves in this capacity for Mumm-Ra and Grune.
* MonsterModesty: Slithe doesn't wear much compared to the [=ThunderCats=].
* MythologyGag: In "Song of the Petalars", Slithe adds a "Yes." to the end of his sentence when speaking, a nod to the original's more severe VerbalTic.
* OnlySaneMan: Compared to [[AxCrazy Kaynar]] and [[ImAHumanitarian Addicus]], anyway.
* ReptilesAreAbhorrent: He's a lizard man who works for Mumm-Ra.
* ShoutOut: As with the original, his design is a tribute to the Orcs from Creator/{{Rankin Bass|Productions}}' ''WesternAnimation/TheHobbit''.
* TheStarscream: In "Between Brothers," he proved just how far his "loyalty" to Mumm-Ra really goes by going along with Grune's idea to destroy the entrance to the Astral Plane while Mumm-Ra was still inside it.
* UnfriendlyFire: As mentioned in TheStarscream, he ordered his forces to destroy the hut that held the portal to the Astral Plane...knowing full well that Mumm-Ra was still in there.
* WeHaveReserves: He wanted to burn down the Briar Woods to get the [=ThunderCats=]. The fact that his scouting party was still inside did nothing to deter him.
--> '''Slithe''': "They are expendable... as are ''you'', Lieutenant!"
[[/folder]]

[[folder:Kaynar]]
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/Kaynar_mugshot_225px_7684.png]]
-->''Voiced by'': Creator/DeeBradleyBaker

A Jackalman and one of Mumm-Ra's two new generals. He is the new version of Jackalman from the original series.
----
!!Tropes associated with Kaynar:
* AdaptationNameChange: From Jackalman to Kaynar
* AdaptationalBadass: He even ''looks'' more dangerous!
* AxCrazy: While in prison, Kaynar has to be strapped to a gurney and heavily restrained just to be moved to solitary confinement, which he earned after killing eleven inmates. He's pretty sanguine about his punishment:
--> '''Kaynar:''' At least I'll have the voices in my head to talk to.
** He wasn't even intereted in Sliithe freeing him till he was told he could 'play' with some cats.
* BloodKnight[=/=]{{Sadist}}: He loves fighting and killing people.
* TheBrute: Shares this role with Addicus.
* EatsBabies: Gives some thought to eating one of the Thunder Kittens.
* EvilRedhead: Orange fur, but still creepy as hell.
** CurtainsMatchTheWindows: Orange-red fur, and similar-hued eyes.
* GigglingVillain: He's constantly laughing to himself.
* LaughablyEvil: Comes with being completely insane.
--> '''Kaynar''': "You're like a toy that never breaks! *Lets out a deranged cackle* I love it!"
* PsychoForHire: Emphasis on the "psycho" part. Even Addicus seems to think so, if Lion-O's gambit against him in "Birth of the Blades" is any indication:
--> '''Addicus:''' "You're crazier than Kaynar!"
* TheNoseKnows : The first time he fights Tygra, the Thundercat turns invisible for a stealth attack; but Kaynar defeats him because he can still smell him.
* SerialKiller: He's killed many without remorse.
* ShippedInShackles: In his first appearance in "New Alliances".
* SlasherSmile: The above image provides a good example.
[[/folder]]


[[folder:Addicus]]
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/Atticus_mugshot_225px_2377.png]]
-->''Voiced by'': Creator/RobinAtkinDownes

A Monkey and one of Mumm-Ra's two new generals. He is the new version of Monkian from the original series.
----
!!Tropes associated with Addicus:
* AdaptationNameChange: From Monkian to Addicus.
* AdaptationalBadass: Bigger, smarter, and more dangerous than his 80's counterpart.
* BloodKnight: His savagery is specifically why Mumm-Ra wanted to recruit him in the first place.
* TheBrute: Shares this role with Kaynar.
* CarryABigStick: Not as massive as Grune's and lacking the lightning projectiles, but Addicus does swing around a mean-looking double-headed mace.
* EvenEvilHasStandards: Through he may be a psychopath, even he's not very fond of Kaynar.
* FaceDeathWithDignity: In his debut, he's about to be executed by members of the Bird Nation for his crimes. Hanging upside-down over a deep gorge with seemingly no way out, his only response is to sneer at his executioners.
--> '''Addicus:''' "You'd better hope that this fall is enough to kill me!"
* ImAHumanitarian: He seems to have an appetite for members of other sentient races. Starting with his avian would-be executioners and going from there.
** Of course, from what [[FantasticRacism we see later of the birds]], they may qualify as [[AssholeVictim Jerkass Victims]].
* KillerGorilla : Considering his general looks and lacking a tail, he's more an ape than a monkey. The 'killer' part is very detailed in the below and above tropes.
* PsychoForHire: Not ''quite'' as crazy as Kaynar, but he's far from a well-balanced individual.
* SerialKiller: He was about to be executed for such crimes before Slithe intervened.
* VerbalTic: As of "The Trials of Lion-O" he can be heard making monkey grunts similar to his 80's counterpart. It serves as a bit of a ContinuityNod for fans of the original series.

[[folder:Ancient Spirits of Evil]]
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/770px-TCats_Ep17_Still_5_6880.jpg]]
--> ''Voiced by'': Creator/JimCummings1952 ("Native Son"), Creator/KevinMichaelRichardson ("Birth of the Blades")

Evil beings who were once worshipped, and give Mumm-Ra his mystic dark power.
----
!!Tropes Associated with the Ancient Spirits of Evil:
%%* BigNo: Deliver one near the end of "Native Son".
* DarkIsEvil: They appear as shadows and are even referred to as spirits of evil.
* {{Expy}}: One of them looks exactly like the Egyptian God Anubis.
* EveryoneCallsHimBarkeep: We only know them by the group title.
* FateWorseThanDeath: [[spoiler: Revealed to have inflicted one on the Tigers: first they let the plague run its course, which killed them all, and then they cursed them to exist as ghosts who would become monsters every nightfall]]
* {{Foreshadowing}}: The ''reason'' they wanted Tygra dead? [[spoiler:He will be a thorn in their side when he grows older]].
* GodOfEvil: They ''are'' called the [[ExactlyWhatItSaysOnTheTin Ancient Spirits of Evil]].
* GreaterScopeVillain: These are the ones that Mumm-Ra answers to.
* SelfFulfillingProphecy: [[spoiler: Their desire to see Tygra dead created the very thorn they wanted to avert.]]

[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/Thundercats-Song-of-the-Petalars-069_1313204395_6897.jpg]]
-->''Voiced by'': Creator/JamesArnoldTaylor, Creator/MatthewMercer, and Creator/KevinMichaelRichardson

Three elite lizard commandos who tracked Lion-O and his group into the brambles. They answer directly to General Slithe.

----
!!Tropes associated with Khamai, Kask, and Sauro:
* BareFistedMonk: Kask has a shield, but seems to prefer using martial arts to take down his prey.
* InvisibilityCloak: Being based on a chameleon, Khamai can turn invisible much like Tygra can.
* TheNoseKnows: Sauro is able to catch the scent of the Cats' trail
* ScarilyCompetentTracker: They don't lose sight of any of their targets.
* ShoutOut: The three of them together with Slithe are similar to the band of Mutants from the original series.
* UncertainDoom: The last we see of them is being left in an unconscious heap before Slithe loses patience and has his troops set the whole forest on fire.

[[folder:The Driller]]
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/driller_5567.png]]
-->''Voiced by'': Creator/MatthewMercer

The Driller is a giant automaton tasked by Mumm-Ra to work in the Thundrilium mines. He is able to transform into a double ended drill and can bore through almost any surface.
----
!!Tropes associated with The Driller:
* AdaptationalBadass: He is much more menacing and threatening than the relatively simplistic version from the original.
* LoadBearingBoss: After [[spoiler: Lion-O defeats him in "Old Friends", the mine around the [=ThunderCats=] begins to collapse from the damage he'd caused.]]
* MeaningfulName: Apart from having several drills on his frame, the robot's purpose is to drill through subterranean rock.
* MechanicalMonster: He's a malevolent machine.
* RedEyesTakeWarning: His blood-red optics, combined with his service to Mumm-Ra, lead to this trope taking effect.
* ThisIsADrill: It's all in the name.
* TransformingMecha: He even looks like a [[Franchise/{{Transformers}} Decepticon]]. His transformation isn't exactly complex, though.
* UseYourHead: at the climax of the fight, he uses the drill on his head to try and kill Lion-O.
** ViolationOfCommonSense: Never mind that he had two perfectly-large drills on his ARMS to engage in the clash with...

[[folder:The Duelist]]
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/theduelist_2348.png]]
-->''Voiced by'': Creator/MiguelFerrer

The best swordsman in the land, the Duelist challenges those whose weapons he admires to duels, so he can claim their swords as trophies.
----
!!Tropes associated with The Duelist
* AmazingTechnicolorPopulation: Light purple skin.
* BadassLongcoat: Sports an extremely elaborate caped military tailcoat.
* BreakTheHaughty: He's an arrogant, condescending master swordsman who's robbed several skilled swordsmen of their prize blades [[spoiler: including, for a time, Lion-O's Sword of Omens]]. When Lion-O bests him [[spoiler: during their rematch ]], his attempts to get even only result in further humiliation [[spoiler: at the hands of Hattanzo/the Drifter]].
* CollectorOfTheStrange: Likes unique swords, especially when wielded by inexperienced users. Care to make a wager?
* CombatPragmatist: Averted for the most part; while he tends to goad more arrogant fighters into matches, he relies on pure swordplay. [[spoiler: Until Lion-O beats him in their rematch, when he tries to pull a dagger on the young king when his back is turned.]]
* {{Cool Sword}}s: He has several, and he's always looking for more.
* DualWielding: Favors a SinisterScimitar and a RoyalRapier.
* EvilSoundsDeep: He has a smooth, dark baritone, courtesy of Miguel Ferrer.
* GlowingEyesOfDoom: At night, his already [[RedEyesTakeWarning red eyes]] glow.
* HustlingTheMark: A variant. At no point does he ''feign'' incompetence around his [[TheCon marks]]. Instead, he capitalizes on their naiveté - both of his own MasterSwordsman status, and out of misplaced {{pride}} in their own skills- to goad them into dueling him. Oh, and he also neglects to mention that when his foe puts their sword up against his "best blade," he'll have one [[DualWielding in his other hand]]. Presto, one more sword for his portable shield rack.
* MasterSwordsman: It's all in the name.
* NamedWeapons: Likely has plenty, but the only one given is the Sword of Hattanzo. [[spoiler: And the Sword of Omens (for a few hours).]]
* PointedEars: He has pointy ears.
* ProfessionalGambler: Winner takes all. And he always wins.
* PunnyName: He's a duelist, who's a [[DualWielding dualist]].
* RapidFireFisticuffs: With his swords rather than his fists, but the spirit of the attack is basically the same.
* RedBaron: One assumes that "the Duelist" wasn't his birth name.
* RedEyesTakeWarning: Red irises on deep maroon sclera.
* RoyalRapier: His right-hand sword, to go along with his {{Swashbuckler}} aesthetic.
* RubberForeheadAlien: A rare creature on a planet of HumanoidAliens and {{Beast M|an}}en.
* SamuraiCowboy: A gunslinger with swords, in {{Swashbuckler}} togs just to further [[NinjaZombiePirateRobot confound classification]].
* SinisterScimitar: His [[IncrediblyLamePun left-hand]] sword, the famous Sword of Hattanzo.
* SmugSnake: A master at his art, who assumes he's unbeatable. [[spoiler: When Lion-O beasts him, he quickly resorts to an attempt at foul play. Luckily, Hattanzo/the Drifer will have none of that.]]
* SpellMyNameWithAThe: Really, Lion-O should have known he was bad news.
* {{Swashbuckler}}: A walking refugee of the genre incongruously traipsing around a CattlePunk[=/=]''{{Wutai}}'' and challenging victims to a classic ShowdownAtHighNoon.
* VillainousCheekbones: Very high and narrow.
* VillainsOutShopping: When Lion-O seeks him for a rematch, he finds the Duelist slicing up lime for the drinks of his peers.
* VillainousWidowsPeak: He has a widow's peak and he's not a nice guy.
* WalkingArmory: He carries all of the swords he took from his opponents on his back.

[[folder:Conquedor]]
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/Conquedor2_225px_897.png]]
-->''Voiced by'': Creator/JonPolito

A merchant slaver and trafficker who captures Ro-Bear Bill's family. He captures and sells all sorts of things, from Berbils to [[MythologyGag large cats]]. [[KickTheDog Making him the ultimate scumbag]].

----
!!Tropes associated with the Conquedor
* {{BFG}}: His rifle is ''huge.''
* CanonCharacterAllAlong: [[WhatCouldHaveBeen Had season 2 happened]], it would turn out the Conquedor was in fact a re-imagining of classic series villain, Safari Joe.
* CoolHelmet: Wears a modified conquistador's morion.
* EgomaniacHunter: He treats his hunting and enslaving of Berbils as good sport.
* FatBastard: Rather corpulent, rather cruel.
* HighClassGlass: He wears what look like infrared googles.
* HuntingTheMostDangerousGame: Seeing as he was meant to be a re-imagining of Safari Joe, this trope comes into play. He prefers to take his prey alive to sell as slaves.
* MalevolentMaskedMan: Or whatever the heck he is.
* RedEyesTakeWarning: His mask sports red goggles, and he's a villain.

[[folder:Ratar-O]]
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/rataro_6961.png]]
-->''Voiced by'': Carlo Rota

Tyrannical ruler of the Rats in Mount Plun-Darr and the descendant of Ratilla. He enslaved the cats, forcing them to work in the mines and search for the Sword of Plun-Darr.
----
!!Tropes associated with Ratar-O:
* BadBoss: He regularly abuses and belittles his direct subordinate for petty reasons. [[spoiler:[[TheDogBitesBack It comes back to bite him big-time when said subordinate decides to side with Lion-O by throwing him his sword and gauntlet. ]] ]]
* DualWielding: Ratar-O's Weapons Of Choice are his twin Rat Eye Daggers, which are able to [[SwordBeam shoot energy bolts]] when crossed together to charge their power.
* FauxAffablyEvil: Acts refined and sophisticated, but is as brutal as any other villain. Which leads right into him being a...
* FatBastard: He's an overweight slave driver who constantly insults and mistreats Mordax.
* JerkassHasAPoint: He's a villain and a tyrant, make no mistake. But considering what we knew of Thundera's FantasticRacism towards the lizards, his claim that the cats didn't want to share similar power with other races (hence why they sent Jaga to reclaim the Sword of Plun-Darr from Ratilla) may have more weight to it than we know...
* KickTheDog: When two cat slaves overpower his underling and try to make a run for it, he chases them into a dead end, taunts them for their failure, and unleashes a single blast of energy from his crossed daggers. Then he walks away with a wicked chuckle. [[GoryDiscretionShot We don't actually see the aftermath, but that might be for the best]].
* LargeAndInCharge: Assuming that paunch isn't just padding from the armor, Ratar-O has a belly on him. He's noticeably taller than his men. Naturally, he's [[IncrediblyLamePun the big cheese]].
* MythologyGag: His design is very close to how he looked in the original series, but closer inspection shows that he actually looks more like the original Ratilla, at least in terms of costume design.
* OhCrap: Gets one of these [[spoiler: when Lion-O gets his sword and gauntlet back, courtesy of TheDogBitesBack.]]
** And another one when [[spoiler: Lion-O's gauntlet generates an energy field to harness the blast from his Rat Eye Daggers, allowing Lion-O to reflect that power right back at him.]]
* RankScalesWithAsskicking: The leader of the rats proves to be a rather capable fighter when Lion-O faces him, and even puts the Lord of the Thundercats on the defensive.
* ShadowArchetype: Like Lion-O, he's the leader of his people, has claim to an ancestral weapon (the Sword of Plun-Darr to Lion-O's Sword of Omens), and wields an enchanted blade (his Rat's Eye Daggers). However, where Lion-O is a noble leader who respects his team as friends, Ratar-O is a harsh tyrant who berates his servants (Mordax, in particular) for so much as speaking out of turn.
* TennisBoss: Lion-O ultimately defeats him by using his gauntlet to block the energy from Ratar-O's FinishingMove, then [[HoistByHisOwnPetard deflects it right back at him.]]
* ThirdEye: Not literally, but his helmet ''does'' have a third eye motif.
* YouDirtyRat: He's an unscrupulous rat man.
* WellIntentionedExtremist: Claims that his motivation for all his cruel deeds - enslaving the cats and having them mine a dangerous cave for the Sword of Plun-Darr - was that he can lead his people to glory, no longer living off the scraps of the cats or any of the other races. [[spoiler:Except, as Lion-O himself puts it, his people "are just slaves on the other side of the whip," which Ratar-O doesn't deny.]]
* WickedCultured: As mentioned under FauxAffablyEvil, he generally acts like quite the cultured nobleman.
[[/folder]]

[[folder:Mordax]]
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/mordax_3359.jpg]]
-->''Voiced by'': Creator/KevinMichaelRichardson

Rataro's underling, who must constantly suffer his abuse.
----
!!Tropes associated with Mordax:
* AntiVillain: He really only seems to want to see the Rats regain their old prosperity; and he chafes under Ratar-O's cruelty as much as the cat slaves.
* TheDogBitesBack: See ScrewThisImOuttaHere. [[spoiler:He also kicked Lion-O's sword and gauntlet back to him, thereby ensuring that Lion-O would have a fighting chance against his abusive master.]]
* EvilOldFolks: Something of an aversion, as he claims he was JustFollowingOrders to whip a cat-slave when Pumyra attacks him. [[spoiler:In a much more clear aversion, he performs a ScrewThisImOuttaHere on Ratar-o [[TheDogBitesBack and throws Lion-O his sword and gauntlet.]]]]
* EyepatchOfPower: Averted somewhat; he's never shown to be a very capable fighter.
* GigglingVillain: [[spoiler:Averted, his only menacing snicker really comes when he turns on his boss by throwing Lion-O his weapons.]]
* JustFollowingOrders: He pulls this excuse when Pumyra attacks him for whipping one of the cat-slaves. She doesn't consider it much of an excuse.
* MiniatureSeniorCitizens: Smaller than just about everyone, making it easier for Ratar-O to abuse him. And for Pumyra as well, when she catches him whipping an enslaved cat.
* MixAndMatchWeapon: His weapon is a hybrid sickle and whip, similar to the Japanese ''[[http://en.wikipedia.org/wiki/Kusarigama Kusarigama]]''.
* NoHoldsBarredBeatdown: He's on the wrong end of one after Pumyra gets ahold of him.
* ScrewThisImOuttaHere: He abandons Ratar-O after suffering under his abuse and being shown mercy by Lion-O.
* UngratefulBastard: Lion-O just saved him from a wrathful Pumyra. His idea of gratitude? Pull a scythe on Lion-O, forcing him, Pumyra, and Panthro to surrender. [[spoiler: Ultimately averted, as he ends up turning against Ratar-O ''because'' [[BecauseYouWereNiceToMe Lion-O showing him mercy]] was more kindness than his own master had ever given him]].

[[folder:Vultaire]]

-->''Voiced by'': Creator/MichaelMcKean
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/vulfuckingtaire_5738.jpg]]
The prefect of Avista and its avian inhabitants. Pretty much this show's version of Vultureman from the original series.

----

* AdaptationalBadass: Unlike his '80s counterpart, he has wings so he can fly on his own.
* AdaptationNameChange: Not to the same extent as Addicus or Kaynar, but here it's Vultaire instead of just Vultureman.
* AntiVillain: Ostensibly a [[SlidingScaleOfAntiVillains Type]] [[WellIntentionedExtremist III]] or even a [[HeroAntagonist Type IV]]. Sure, he's an arrogant twit and antagonistic to the [=ThunderCats=], but they pretty much stormed into his city and intended to steal a power stone that [[spoiler:is vital for Avista's survival]]. He's not even shown to be tyrannical (as one would assume from his social position), and has shown [[EvenEvilHasStandards moral disdain]] towards the cats' past tyranny against other species.
** The "Anti" part goes away [[spoiler:when he joins Mumm-Ra out of fear and the temptation of power.]]
* DirtyCoward: [[spoiler:He joins Mumm-Ra and abandons his people just so that he can save his own hide.]]
* FantasticRacism: Towards the cats, since the birds, much like pratically everyone else, sees them as tyrants and barbarians.
* FeatheredFiend: He's a bird man and an antagonist, until [[spoiler:he becomes an outright villain by joining Mumm-Ra]].
* {{Hypocrite}}: Calls the [=ThunderCats=] out for their FantasticRacism against the other animal clans... but it's pretty clear that he has a lesser opinion of anyone who isn't of the Bird people, himself. [[spoiler:And then he betrays his own race to Mumm-Ra.]]
* {{Jerkass}}: And how.
* JerkassHasAPoint: [[NiceJobBreakingItHero Thanks for proving him right]] about cats being violent berserkers, [[spoiler:Pumyra]].
* MeaningfulName: His name sounds similar to the political philosopher {{Creator/Voltaire}}, and like the philosopher is an intelligent man who disapproves of infringing on rights of others, as shown by his dislike for the Cats using the War Stone to keep weaker species in-line.
* TheQuisling: [[spoiler:He is the only Bird to accept Mumm-Ra's offer.]]
* SacredHospitality: Despite barely hiding his FantasticRacism, he was a fairly decent patron until the [=ThunderCats=] demanded the Tech Stone.
* SmugSnake: Arrogant and haughty to an insufferable degree.
* SoreLoser: Accepts Tygra's challenge to a flying race for the Tech stone with the War and Spirit stones on the line. When Tygra wins, he declares the wager null and void, and has the [=ThunderCats=] placed under house arrest. In fairness, he wasn't really in a position to give the tech stone away, though that just emphasizes his arrogance in accepting the wager in the first place.
* WingedHumanoid: Emphasis on "winged," as he's a bird.
