Lord of The [=ThunderCats=].
Tropes associated with Lion-O:
* TheAce: Invoked in a mini-series arc: To officially claim his title of Lord of the [=ThunderCats=], he has to beat each of them in a contest at whatever they're best at. He manages it by cleverness or exploiting a weakness. (For instance, Cheetara can only maintain SuperSpeed over a short distance race, not a marathon.)
* BareYourMidriff: His armour has a conspicuous opening for his abs.
* [[CuriousAsAMonkey Curious As A Kitten]]: Almost as bad as The Thunder Kittens.
* EmpathicWeapon: The Sword of Omens.
* GreenLanternRing: The Sword of Omens again.
* TheHero: Main Good guy.
** IdiotHero: Well, he is very naive due to being a kid in an adult's body.
* TheLeader: First a Type IV; he's only the leader because he's the prince. Later matures into a type II, becoming responsible and taking his role more seriously.
* MagicalIncantation: The Sword of Omens has two.
** "Thunder, Thunder, Thunder...Thunder Cat HO!"
** "Sword Of Omens, give me sight beyond sight!"
* HotBlooded
* PalantirPloy: "Sword Of Omens, give me sight beyond sight!"
* PlotRelevantAgeUp
* RedHeadedHero
* YoungerThanTheyLook: Lion-O is actually the youngest member of the cast. The only reason he looks so old is that his suspension pod broke during the escape from Thundera, causing him to age in his sleep while the others all remained the same. He spends most of the (early) series [[CharacterDevelopment learning to be a mature and responsible leader]].

Tropes associated with Panthro:
* BaldOfAwesome[=/=]FurryBaldness
* TheBigGuy: Panthro is a Class V hands down. Not only the physically strongest member of the team, but he also ''built'' every piece of technology the [=ThunderCats=] use, starting with the [[CoolCar Thundertank]].
** Practically spelled out in the first episode, when the Mutants attack:
--->''"Hahaha! If you guys were as mean as you were ugly..." *effortlessly blocks and crushes a Mutant's mace with one hand* "...then maybe you'd be trouble!"''
* EpicFlail: His battle sticks, aka nunchucks, which he could load with tricks like [[BubbleGun high pressure bubbles]]... or compact ''[[KillItWithFire flamethrowers]]'' for a fight.
* GadgeteerGenius: He was able to build the Thundertank using components that he ''[[InsistentTerminology salvaged]]'' from the [=ThunderCats=]' wrecked ship.
* GeniusBruiser
* MrFixit
* WhyDidItHaveToBeSnakes: He's afraid of bats, and in one episode admits that he hates spiders, too.

-> Voiced by Peter Newman
Tropes associated with Tygra:
* DesignatedVictim: If someone has to get mind-controlled, captured, or otherwise endangered, it's probably going to be him.
* InvisibilityCloak: His whip.
* TheLancer
* MasterOfIllusion: ItOnlyWorksOnce.
* TheSmartGuy
* WeaksauceWeakness: Early on, he couldn't swim unless he was invisible (ironically, tigers are one of the few cats who ''don't'' hate water).
* WhipItGood

-> Voiced by Lynne Lipton
Tropes associated with Cheetara:
* ActionGirl
* BlessedWithSuck: She specifically calls her sixth sense a curse, as using it tends to nearly kill her.
* TheChick: Although she can definitely hold her own in combat.
* FragileSpeedster
* PsychicPowers
* SimpleStaff
* SuperSpeed
* TeamMom

!!The Thunder Kittens: [=WilyKat=] & [=WilyKit=]
-> [=WilyKat=] voiced by Peter Newman, [=WilyKit=] voiced by Lynne Lipton
Tropes associated with the Thunder Kittens:
* {{Bratty Half Pint}}s: Frequently.
* [[CuriousAsAMonkey Curious as a Kitten]]: Ancient tombs, DeathTrap-filled towers, spooky caves, whatever. If it's ominous and likely to be dangerous, they're going to poke around in it.
* GenkiGirl: Wilykit
* IdiotBall: The plot would occasionally get started because they decided it'd be fun to, say, open up an ancient tomb or "borrow" the others' weapons without permission.
* {{Keet}}: Wilykat
* ParentalAbandonment: No explanation is ever given for who the twins' parents were or what happened to them.
* SiblingSenioritySquabble: In the Wildstorm comics, at least. Wilykat does ''not'' like being called "Little Brother."
* [[SheIsAllGrownUp They Are All Grown Up]]: In the comic miniseries ''[=ThunderCats=]: The Return''. Puberty was very good to them. (Also FetishFuel.)
* {{Tagalong Kid}}s
* {{Tricksters}}: Most of their weapons and tactics rely on misdirection, blinding opponents, etc.
** TricksterTwins

!!Snarf (AKA [[spoiler: Osbert]])
-> Voiced by Bob [=McFadden=]
Tropes associated with Snarf:
* EmbarrassingFirstName: Snarf hates his real name and berates Snarfer any time he uses it.
* IncorruptiblePurePureness: He is immune to most forms of mind control and possession. Jaga explains that [[AlwaysLawfulGood his species is incapable of having evil in their hearts.]]
* LovableCoward
* PokemonSpeak (since he doesn't use his real name)
* TeamPet: A different species from the others, serves as the pet to the team. Utterly useless in a fight except against the weakest of minions, and tends to serve as weak comedy relief. Subverted only slightly in that Snarf is actually the nanny for Lion-O before he wakes up all growed-up on Third Earth. Occasionally subverted but those occasions also meant that Cats who should have known better didn't.

-> Voiced by Earl Hammond
Tropes associated with Jaga:
* BadassGrandpa
* BigDamnHeroes: As a ghost, he saved the day because he was the only character who could hit Grune The Destroyer.
* {{Cincinnatus}}: Lion-O's father was blinded in a battle against the Mutants, so he turned power over to Jaga until Lion-O would be ready to claim the title of Lord of the [=ThunderCats=].
* CoolOldGuy
* HeroesPreferSwords: If not the Sword of Omens then a regular long sword.
* TheMentor[=/=]TheObiWan
* OurGhostsAreDifferent
* SpiritAdvisor

-> Voiced by Doug Preis
Tropes associated with Lynx-O:
* BadassGrandpa
* BareFistedMonk
* CoolOldGuy
* DisabilitySuperpower: He seems to have a radar sense similar to ComicBook/{{Daredevil}}.
* EyesAlwaysShut: Due to blindness via burned eyes.
* HandicappedBadAss: Despite being blind, he fights (and often wins) without a weapon and he can even fly a plane using a special board and his radar sense!
* PressurePoint: Part of his fighting style.
* TeamDad: Due to being the oldest. Moreso with Pumyra and Bengali than with the rest of the Cats.

-> Voiced by Gerrianne Raphael
Tropes associated with Pumyra:

* AffirmativeActionGirl
* AnimalEyes: Subverted, she's the only Thundercat with round, human-like pupils
* TheChick: Even more than Cheetarah
* InASingleBound
* TheMedic
* OutOfFocus: She appears in the fewest number of episodes and disappeared almost completely near the end.
* SkunkStripe
* TechnicalPacifist
* WeaponOfChoice: A sling, possibly combined with WhipItGood.

-> Voiced by Peter Newman
Tropes associated with Bengali:
* TheBlacksmith: He's one of the few individuals capable of repairing the Sword of Omens.
* DropTheHammer
* HotBlooded: After Lion-O spends the first half of the series learning to keep a cool head.
* UnrelatedBrothers: He and Tygra often refer to each other as brothers, probably because they are both tiger-based Thundarians.

-> Voiced by Peter Newman
Tropes associated with Hachiman:
* AbsurdlySharpBlade: As Monkian describes, "Did you see that!? He chopped through solid stone!"
* DidYouJustPunchOutCthulhu: Fights two of the Ancient Spirits of Evil in armed combat and shatters them. While a temporary defeat and the statues soon reformed; it was notable that when an infuriated Mumm-Ra transformed after that to deal with Hachiman himself, he didn't feel as strong as usual and his powers were reduced.
* EmpathicWeapon: His katana, "Thundercutter," which will not come out of its scabbard if Hachiman tries to use it to perform an act of evil (like say, any order by Mumm-Ra).
* [[EverythingsBetterWithSamurai Everything's Better With Samurai]]
* HonorBeforeReason: Oh sure, just keep hacking away at the narrow bridge over the near-BottomlessPit you and Lion-O are both standing on until he agrees to backtrack and let you pass. You might both fall to your death, but at least you'll maintain your pride as a samurai! (Not that [[HotBlooded Lion-O]] was behaving any better at the time, mind you.)
* HorribleJudgeOfCharacter: Come on, he was fooled by Mumm-Ra twice even though he wasn't using any disguises or anything.
* KatanasAreJustBetter

!!Queen Willa
-> Voiced by Lynne Lipton
Queen of the [[AmazonBrigade Warrior Maidens]].
Tropes associated with Queen Willa:
* DoesNotLikeShoes: Like the rest of the Warrior Maidens, she goes barefoot.
* ThePowerOfActing: She was once able to trick the bad guys into thinking she had gone over to TheDarkSide, so she could surprise them. It was quite convincing.

-> Voiced by Lynne Lipton
Queen Willa's younger sister.
Tropes associated with Nayda:
* DoesNotLikeShoes

!!Snowman of Hook Mountain
-> Voiced by Earl Hammond
Tropes associated with Snowman:

* BigfootSasquatchAndYeti
* CoolHorse: Snowmeow, a huge cat who serves as Snowman's mount.
* AnIcePerson: He can create weapons out of ice.

!!Mandora the Evil-Chaser
-> Voiced by Lynne Lipton
Tropes associated with Mandora:
* NotSoStoic: A no-nonsense by the book cop, and that's putting it lightly. However, she does care deeply for her friends. When space marauders were about to dismember the reformed pick-pocket Quick-Pick unless she surrendered, she suddenly broke her formality and yelled at them to stop before giving herself up. Lion-O later rescues her and gets captured so Quick-Pick can escape with her. Upon regaining consciousness; she urges Quick-Pick not to lose the pirates' ship or they may never see Lion-O again.
* SpacePolice
* SuperCop

!!Dr. Dometone
Tropes associated with Dr. Dometone:
* BaldOfAwesome
* IntergenerationalFriendship: Between him and Wilykit.
* TheProfessor

Tropes associated with Mumm-Rana:
* ByThePowerOfGrayskull: "Ancient Spirits of Goodness, transform this gentle form to Mumm-Rana, the Ever Good."
* DistaffCounterpart: To Mumm-Ra.
* LightIsGood
* AmuletOfDependency
* WeakWilled

Tropes associated with Mumm-Ra:
* AchillesHeel: He can only leave his sarcophagus for 24 hours at a time.
* AsLongAsThereIsEvil: "As long as evil exists, ''Mumm-Ra lives!''"
* BadBoss
* BigBad
* ByThePowerOfGreyskull: (Villain variant) "Ancient Spirits of Evil, transform this decayed form into Mumm-Ra, the Ever... LIVING!!!"
** UpToEleven with "Ancient Spirits of Evil, transform Mumm-Ra, the Ever Living into Mumm-Ra, the All... POWERFUL!!!"
* CardCarryingVillain: As glaring an example as they come, even by Eighties cartoon standards.
* ChronicBackstabbingDisorder
* EvilLaugh
* EvilPlan
* EvilSorcerer
* LargeHam
* LetsYouAndHimFight: Invokes this a lot.
* MasterOfDisguise: Most of his plots involve disguising himself as an innocent or an ally and luring the [=ThunderCats=] into a trap.
* {{Mummy}}
* OneWingedAngel: By invoking the Ancient Spirits of Evil, he can assume the form of Mumm-Ra the Everliving, which is far more physically adept than Mumm-Ra is. He also turns into an even-more powerful version called Mumm-Ra the Allpowerful in one episode.
* OrcusOnHisThrone: Spends most of his time lurking in his tomb in his pyramid. Justified because he can only survive outside of his coffin for 24 hours and he needs to keep the chamber where he invokes the Ancient Spirits of Evil protected, lest someone steal their power from him.
* OurLichesAreDifferent: He looks more like a mummy and can transform into more life-like super-powered form
* PetTheDog: Toward his actual pet dog, Maa-Mutt. He's genuinely horrified when Maa-Mutt is exiled in "The Last Day", and at the end of "Maa-Mutt's Confusion" he frantically digs him out of the wreckage of his destroyed WeaponOfMassDestruction and apologizes for abusing him earlier.
* PalantirPloy: His pool can show images at any location.
* TimeAbyss: "I remember when this was first Earth."
* VoluntaryShapeshifting
* WeaksauceWeakness: His own reflection.

!!The Ancient Spirits of Evil
* BadBoss: Their chief servant, Mumm-Ra, gets away with being chastised or zapped for failure whereas other minions are either left to their own fate or disintegrated without a word.
* BerserkButton: Mumm-Ra learns the hard way that they do NOT take kindly to being taken for granted.
* BiggerBad: An overwhelming evil force that relies on others to carry out its will.
* DealWithTheDevil: Mumm-Ra mentioned having to pay a price for leaving his tomb and that no one should learn about it.
* DontTouchItYouIdiot: Warned Mumm-Ra that continuing his scheme to unlock the secrets of the Book of Omens will spell the end of their evil powers on New-Thundera.
* EldritchAbomination: Cheetara nearly suffered a breakdown when her sixth sense detected a dark activity, The Eye of Thundera also warned of something out there but would not show Lion-O the source of it.
--->'''Cheetara''': It can't be! So evil!!
* KickTheDog: To demonstrate the punishment in-store for Mumm-Ra should he fail this time; they condemn Ma-Mutt to eternal exile in space much to his master's grief.
* PetTheDog: Even the powers of evil and wickedness have their off days: Lost in the ruins of his pyramid on New-Thundera, a distressed Mumm-Ra can only communicate with his home on earth through the cauldron telling his saddened dog how much he misses him. The Ancient Spirits of Evil reunite him with his beloved pet. After rescinding his exile from "The Last Day" they also bother to bring back Ma-Mutt. Finally, after Mumm-Ra's many failures, they admit to him that they may have underestimated the Thundercats and provide him with help rather than punishment.
* RedEyesTakeWarning: The eyes of the beast statues in the black pyramid light up whenever they become involved (transforming/resurrecting Mumm-Ra) or are angered. Examples for the latter are when Lynx-O and Cheetara entered the pyramid's inner sanctum, when Mumm-Ra declared he had no need for them anymore, and most jarringly when the Thundercats destroyed the black pyramid and left without noticing the furious glowing eyes amongst the rubble.
* ReptilesAreAbhorrent: One of the man-beast statues has a crocodile's head.

!!Grune The Destroyer
Tropes associated with Grune:
* CarryABigStick
* FaceHeelTurn: In the backstory.
* FashionableAsymmetry: He's initially recognized by virtue of only possessing one saber tooth.
* OurGhostsAreDifferent: Even compared to the other [[TheObiWan major ghost]] in the series--he can manipulate people and physical objects like a poltergeist, he isn't tinted blue, and he's able to wield a mace made of [[KryptoniteFactor thundranium]] like it was nothing.
* SealedEvilInACan

!!Safari Joe
Tropes associated with Safari Joe:
* BadassMustache
* BaldOfEvil
* {{BFG}}
* CatchPhrase: "Safari Joe does it again!"
* DirtyCoward: When he is cornered and disarmed.
* EgomaniacHunter
* HighClassGlass: He has a monocle, after all.
* LargeHam: Memorably!

!!The Demolisher
Tropes associated with The Demolisher:
* BloodKnight: The only thing that gives his life meaning is battle.
* CombatPragmatist
* JerkAss

Tropes associated with Mongor:
* EmotionEater: Fear makes him stronger and enlarges him to the size of a titan.
* MindOverMatter
* NighInvulnerable: He takes a ''laser blast'' without flinching.
* PlayingWithFire
* SealedEvilInACan
* SinisterScythe

!!The Driller
Tropes associated with The Driller:
* ExactlyWhatItSaysOnTheTin
* PunchClockVillain: He works for anyone who can provide the diamonds he needs to keep his drills sharpened.
* ThisIsADrill

Tropes associated with Ta-She:
* GodSaveUsFromTheQueen: She was an Egyptian queen.
* HypnoticEyes: Only women and Mumm-Ra are immune to her all-consuming beauty.
* SealedEvilInACan: Or a "time-warp prison", to be exact.
* TheVamp

!The Mutants of Plun-Darr
Tropes associated with Ssslithe:
* BigBad --> TheDragon: Early on, he was the BigBad if the mutants were the main enemy that episode. Eventually he became DragonWithAnAgenda to Ratar-O.
* SnakeTalk
* VerbalTic: "Yessss?"
* OnlySaneMan: The other mutants are often ''idiots'', and Ssslithe frequently shows immense frustration with them.

!!Jackal Man
Tropes associated with Jackal Man:
* DirtyCoward
* NotSoHarmlessVillain: Despite his cowardice and lean frame; he is cunning and no slouch in combat.
* TheDragon --> DarkChick: Early on he was Ssslithe's go-to-guy (if an extremely crappy one). By the time Ratar-O showed up he'd become The DarkChick.
* ThoseTwoBadGuys - Along with Monkian

Tropes associated with Monkian:
* BeastMan
* TheBrute
* CrouchingMoronHiddenBadass: Hidden from himself most of all. In the "Deal with the devil" episode he attacks the Thundercats with an unlikely confidence after gaining new powers; thing is, he only really displayed them when dealing with Lion-O and his Sword of Omens, having pretty much outfought and out-skilled the rest of the Thundercats by doing little more than battling them with similar weapons to their own. Justified in that the Thunderian nobles only started using weapons when Jaga handed them their magical weaponry en route to Third-Earth, while Monkian is highly experienced in using a variety of arsenal.
* DealWithTheDevil: Made one with Mumm-Ra in "Monkian's Bargain". Note to self: ''Always'' read the fine print.
* FaceDesignShield: That shoots fire balls.
* KillerSpaceMonkey
* ManiacMonkeys
* VillainousBreakdown: In "Monkian's Bargain".
-->[[spoiler: '''Monkian''': [[BigNo NO!!!]] Let me go!]]

!!Vulture Man
Tropes associated with Vulture Man:
* EvilGenius[=/=]GadgeteerGenius
* InsufferableGenius: Always receives plenty of praise and recognition for his brilliance - only thing is it all comes from himself, and he's often the only one left to hear the end of it.
* RememberTheNewGuy: Literally appeared out of nowhere a few episodes into the series as another mutant.
* TheStarscream: Every plot with Vultureman involved him trying to wrest control of the Mutants from Ssslithe.
* UltimateJobSecurity: Despite '''obviously''' being a traitor, Ssslithe almost never kicks him out for it. Of course, considering [[AlwaysChaoticEvil Mutant culture]], maybe treachery is expected.

Tropes associated with Ratar-O:
* BigBad
* MindOverMatter: One of the powers of his twin sais is to encase his opponents in energy and have them crushed or battered around. Requires concentration though snapping an iron band on his target makes it easier.
* TyrantTakesTheHelm: He steals command of the Mutants from Ssslithe, much to the latter's consternation, and starts running the gang like a DrillSergeantNasty. The only problem? Under Ratar-O the Mutants actually start ''winning''.
* VillainousValour: Takes on an entire army of Tuskas, though in his opinion they are the ones being brave.

!!Ratilla the Terrible
* LargeAndInCharge: The largest mutant shown, towers over Jaga and greatly outbulks him.
* MyDeathIsJustTheBeginning: Warned Jaga to slay him now lest all of Thundera pay for his defeat. Unable to comply due to the code of Thundera; Jaga sentenced him to life in exile and deprived him of the evil Sword of Plundarr by tossing it into the deepest volcano and trapping it within the core of Thundera, an act that eventually doomed the planet itself.
* PredecessorVillain: Appears to be an ancestor of the mutant warlord Ratar-O.
* VillainousLegacy: Ancient commander of the Mutant forces, and original wielder of the legendary Sword of Plundarr. Although defeated long ago, his actions revealed the existence of the treasures of Thundera to later villains, and he was indirectly responsible for Thundera's destruction.

!The Luna - Taks
Tropes associated with Luna:
* BadBoss
* SkunkStripe
* SleepModeSize: Most of the time, she looks like a shriveled little imp with hair that wouldn't look out of place on ''JemAndTheHolograms''. Her true form is taller with even bigger hair... and that's about it.
* UncannyFamilyResemblance: She looks like her ancestor, also [[NamesTheSame named Luna]].
* WhipItGood

Tropes associated with Amok:
* CrouchingMoronHiddenBadass: In one episode, he gets {{revenge}} on Luna for pushing him around one too many times.

* InASingleBound
* PowerFloats
* SuperStrength: He ''snapped'' the Sword of Omens.
