    The Thundercats 


Voiced by Larry Kenney of The ThunderCats.
Tropes associated with Lion-O:
  • The Ace: 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 Super Speed over a short distance race, not a marathon.)
  • Bare Your Midriff: His armour has a conspicuous opening for his abs.
  • Character Development: He matures from One of the Kids and an Idiot Hero into the Big Good over the course of the series.
  • Curious as a Kitten: Almost as bad as The Thunder Kittens.
  • Empathic Weapon: The Sword of Omens.
  • Green Lantern Ring: The Sword of Omens again.
  • Idiot Hero: Well, he is very naive due to being a kid in an adult's body.
  • The Leader: 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.
  • Magical Incantation: The Sword of Omens has two.
    • "Thunder, Thunder, Thunder...Thunder Cat HO!"
    • "Sword Of Omens, give me sight beyond sight!"
  • Hot-Blooded: He's a very impulsive one.
  • Palantir Ploy: "Sword Of Omens, give me sight beyond sight!"
  • Plot-Relevant Age-Up: He's a child when we first see him, but he ended up being aged into an adult because his stasis pod didn't completely halt the aging process.
  • Younger Than They Look: Lion-O is actually around the same age as the Thunderkittens. The only reason he looks so much older 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 learning to be a mature and responsible leader.

Tropes associated with Panthro:
  • Bald of Awesome/Furry Baldness: He has the appearance of baldness even though his body's completely covered in blue fur.
  • The Big Guy: 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 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!"
  • Epic Flail: His battle sticks, aka nunchucks, which he could load with tricks like high pressure bubbles... or compact flamethrowers for a fight.
  • Gadgeteer Genius: He was able to build the Thundertank using components that he salvaged from the ThunderCats' wrecked ship.
  • Genius Bruiser: He's strong in addition to being the team's tech expert.
  • Mr. Fixit
  • Why Did It Have to Be Snakes?: He's afraid of bats, and in one episode admits that he hates spiders, too.

Tropes associated with Tygra:


Voiced by Lynne Lipton
Tropes associated with Cheetara:
  • Action Girl: She's a highly skilled fighter, and gets to save the day after everyone else is defeated on several occasions.
  • Blessed with Suck: She specifically calls her sixth sense a curse, as using it tends to nearly kill her.
  • Fragile Speedster: She can move too fast to be seen, but she's not great at taking punishment.
  • Psychic Powers: Their use is somewhat limited, as they take quite a toll on her whenever used.
  • Simple Staff: It's her Weapon of Choice, although with some of its abilities such as getting as long or short as she requires it to be.
  • Super Speed: Much like cheetahs, she is capable of moving with astounding speed, but can only maintain it for short bursts or distances.
  • Team Mom: She's definitely The Heart of the team, and tries to look after the various other members.

The Thunder Kittens: WilyKat & WilyKit

Tropes associated with the Thunder Kittens:

Snarf (AKA Osbert)

Voiced by Bob McFadden
Tropes associated with Snarf:
  • The Beastmaster: Can communicate with various creatures of Third-Earth, which comes in handy.
  • Beware the Silly Ones: In an early episode he picks a fight with a rhino-like creature at least ten times his size... and wins!
  • Embarrassing First Name: Snarf hates his real name and berates Snarfer any time he uses it.
  • Incorruptible Pure Pureness: He is immune to most forms of mind control and possession. Jaga explains that his species is incapable of having evil in their hearts.
  • Let's Get Dangerous!: He can actually prove to be a valuable member of the team when needed. On one occasion he even saved the others from being captured in Mumm-Ra's pyramid.
  • Lovable Coward: He's not a brave being, but he means well and is often concerned about Lion-O's well-being.
  • Team Pet: 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 grown-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:
  • Badass Grandpa: He's much older than the Thundercats and he guides them to escape the destruction of Thunderra.
  • Big Damn Heroes: 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.
  • Cool Old Guy
  • Heroes Prefer Swords: If not the Sword of Omens then a regular long sword.
  • Heroic Sacrifice: He chose to pilot the Thundercats' ship while the others were in stasis even when aware that he was too old to survive the entire journey.
  • Mentor
  • Nice Job Breaking It, Hero!: After he defeated Ratilla the Terrible, he tried to depose of the Sword of Plundar in Thundera's molten magma. Instead of being destroyed, the sword destabilized the planet and eventually cause it to explode.
  • Our Ghosts Are Different
  • Spirit Advisor: After his death, he occasionally appears before Lion-O as a ghost to give him advice and to warn him when he's making rash decisions.

Voiced by Gerrianne Raphael
Tropes associated with Pumyra:


Voiced by Peter Newman
Tropes associated with Bengali:
  • The Blacksmith: He's one of the few individuals capable of repairing the Sword of Omens.
  • Drop the Hammer
  • Hot-Blooded: After Lion-O spends the first half of the series learning to keep a cool head.
  • Unrelated Brothers: 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:
  • Absurdly Sharp Blade: As Monkian describes, "Did you see that!? He chopped through solid stone!"
  • Did You Just Punch Out Cthulhu?: 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.
  • Empathic Weapon: 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).
  • Everything's Better with Samurai
  • Honor Before Reason: Oh sure, just keep hacking away at the narrow bridge over the near-Bottomless Pit 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 Lion-O was behaving any better at the time, mind you.)
  • Horrible Judge of Character: Come on, he was fooled by Mumm-Ra twice even though he wasn't using any disguises or anything.
  • Katanas Are Just Better: His sword is apparently on the same level of power as the Sword of Omens and Excalibur.

Queen Willa

Snowman of Hook Mountain

Tropes associated with Snowman:

Mandora the Evil-Chaser

Voiced by Lynne Lipton
Tropes associated with Mandora:
  • By-the-Book Cop: Bordering on an Up to Eleven version of the trope.
  • Cool Bike: The Electro Charger.
  • The Faceless: In the form of Hidden Eyes due to a One-Way Visor on her helmet. She never takes it off.
  • Not So Stoic: 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.
  • Space Police
  • Super Cop

Dr. Dometone
Tropes associated with Dr. Dometone:

Tropes associated with Mumm-Rana:


Tropes associated with Mumm-Ra:
  • Achilles' Heel: He can only leave his sarcophagus for 24 hours at a time.
  • As Long as There is Evil: "As long as evil exists, Mumm-Ra lives!"
  • Bad Boss: He's not very nice to the Mutants.
  • Big Bad: He's the main villain.
  • By the Power of Grayskull!: (Villain variant) "Ancient Spirits of Evil, transform this decayed form into Mumm-Ra, the Ever... LIVING!!!"
    • Up to Eleven with "Ancient Spirits of Evil, transform Mumm-Ra, the Ever Living into Mumm-Ra, the All... POWERFUL!!!"
  • Card-Carrying Villain: As glaring an example as they come, even by Eighties cartoon standards.
  • Chronic Backstabbing Disorder
  • Evil Laugh: He does this in EVERY SINGLE EPISODE.
  • Evil Plan
  • Evil Sorcerer
  • Large Ham: Oh yes.
  • Let's You and Him Fight: Invokes this a lot.
  • Master of Disguise: Most of his plots involve disguising himself as an innocent or an ally and luring the ThunderCats into a trap.
  • Mummy: He's covered in bandages.
  • One-Winged Angel: By invoking the Ancient Spirits of Evil, he can assume the form of Mumm-Ra the Ever-Living, which is far more physically adept than Mumm-Ra is. He also turns into an even-more powerful version called Mumm-Ra the All-Powerful in one episode.
  • Orcus on His Throne: 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.
  • Our Liches Are Different: He looks more like a mummy and can transform into more life-like super-powered form
  • Palantir Ploy: His pool can show images at any location.
  • Perpetual Smiler: He always seems to be smiling no matter what mood he's in.
  • Pet the Dog: Toward his actual pet dog, Maa-Mutt. He's genuinely horrified when Ma-Mutt is exiled in "The Last Day", and at the end of "Ma-Mutt's Confusion" he frantically digs him out of the wreckage of his destroyed Weapon of Mass Destruction and apologizes for abusing him earlier.
  • Time Abyss: "I remember when this was first Earth."
  • Voluntary Shapeshifting: He can use his magic to change his form.
  • Weaksauce Weakness: His own reflection.

The Ancient Spirits of Evil
  • Bad Boss: 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.
  • Berserk Button: Mumm-Ra learns the hard way that they do NOT take kindly to being taken for granted.
  • Deal with the Devil: Mumm-Ra mentioned having to pay a price for leaving his tomb and that no one should learn about it.
  • Don't Touch It, You Idiot!: 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.
  • Eldritch Abomination: 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!!
  • Greater-Scope Villain: An overwhelming evil force that relies on others to carry out its will.
  • Kick the Dog: 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.
  • Knight of Cerebus: Any scene with them immediately loses the show's more cheerful side and they display no comical traits whatsoever unlike the other villains.
  • Pet the Dog: 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.
  • Red Eyes, Take Warning: 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.
  • Reptiles Are Abhorrent: One of the man-beast statues has a crocodile's head. (The others are a bull, a boar, and a vulture.)

Grune The Destroyer
Tropes associated with Grune:
  • Carry a Big Stick: His weapon of choice is a large, metal mace. As a ghost, he gives himself an edge against the Thundercats by wielding one made of Thundranium.
  • The Dreaded: When he was alive he was the terror of Third Earth, so much so that long after his death he is still widely feared, and natives can still identify him on sight or even just from descriptions of him.
  • Evil Counterpart: To all the Thundercats somewhat, as he shows what an evil Thundercat could be, but especially to Jaga, who was once his friend and comrade in arms.
  • Evil Former Friend: He and Jaga were once good friends and allies, until Grune's Face–Heel Turn.
  • Face–Heel Turn: In the backstory. He was once Jaga's ally and friend, until greed and a lust for power drove him to rebel against the Thundercats.
  • Fashionable Asymmetry: He's initially recognized by virtue of only possessing one saber tooth.
  • Kryptonite Factor: Inexplicably averted. Thundranium weakens Thundercats, even ghosts like Jaga, but Grune is completely immune to the effects.
  • Names to Run Away from Really Fast: Anybody nicknamed "The Destroyer" is probably not the cuddly sort.
  • Our Ghosts Are Different: Even compared to the other 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 thundranium like it was nothing.
  • Sealed Evil in a Can: After he died on a Third Earth, a magical symbol was placed on the door to his tomb to seal his spirit there and prevent it from ever terrorizing the land again.

Safari Joe
Tropes associated with Safari Joe:

The Demolisher
Tropes associated with The Demolisher:
  • Always Someone Better: Lion-O warns that he will run into this sooner or later rendering his whole life a waste.
  • Blood Knight: The only thing that gives his life meaning is battle.
  • Combat Pragmatist: While muscular and fierce, he will still use any means to win a battle.
  • Ignored Epiphany: For a brief moment after receiving a speech, he breaks the bravado and begins to question his compulsive lifestyle but does not follow through.
  • Jerkass: For a self-proclaimed renowned fighter, he lacks any courtesy or charisma, being gruff and thoroughly condescending.
  • Pet the Dog: Did offer to spare Lion-O when he thought he had him at his mercy, if he would just admit defeat.
  • "Shaggy Dog" Story: He dedicates himself to maintaining his undefeated battle streak, a title which only has value to himself, and should he run into his better he will lose what he based everything on and have nothing else to show for all his efforts.
  • Worthy Opponent: Lion-O acknowledges this and regrets that he didn't join them.

Tropes associated with Ssslithe:

Jackal Man
Tropes associated with Jackal Man:

Tropes associated with Monkian:
  • Beast Man
  • The Brute
  • Crouching Moron, Hidden Badass: 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.
  • Deal with the Devil: Made one with Mumm-Ra in "Monkian's Bargain". Note to self: Always read the fine print.
  • Face-Design Shield: That shoots fire balls.
  • Killer Space Monkey
  • Maniac Monkeys
  • Villainous Breakdown: In "Monkian's Bargain".
    Monkian: NO!!! Let me go!

Vulture Man
Tropes associated with Vulture Man:
  • Evil Genius/Gadgeteer Genius
  • Insufferable Genius: 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.
  • Remember the New Guy: Literally appeared out of nowhere a few episodes into the series as another mutant.
  • The Starscream: Every plot with Vultureman involved him trying to wrest control of the Mutants from Ssslithe.
  • Ultimate Job Security: Despite obviously being a traitor, Ssslithe almost never kicks him out for it. Of course, considering Mutant culture, maybe treachery is expected.

Tropes associated with Ratar-O:
  • Big Bad
  • Mind over Matter: 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.
  • Tyrant Takes the Helm: He steals command of the Mutants from Ssslithe, much to the latter's consternation, and starts running the gang like a Drill Sergeant Nasty. The only problem? Under Ratar-O the Mutants actually start winning.
  • Villainous Valour: Takes on an entire army of Tuskas, though in his opinion they are the ones being brave.

Ratilla the Terrible
  • Large and in Charge: The largest mutant shown, towers over Jaga and greatly outbulks him.
  • My Death Is Just the Beginning: 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.
  • Predecessor Villain: Appears to be an ancestor of the mutant warlord Ratar-O.
  • Villainous Legacy: 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:

Tropes associated with Amok:
  • Crouching Moron, Hidden Badass: In one episode, he gets revenge on Luna for pushing him around one too many times.
  • Dumb Muscle: Although when Luna tosses him aside after retrieving her magic belt, Amok shows he's not so dumb after all.
  • Extreme Doormat: Though he's not above getting revenge on Luna when she goes to far.
  • The Dog Bites Back: Luna learned the hard way, Amok does NOT like being taken for granted and abandoned.
  • The Quiet One
  • You Have Outlived Your Usefulness: Luna abandoned him after becoming taller.
  • Undying Loyalty: He faithfully serves and protects Luna despite the way she treats him. Even after he after he had gotten revenge on her the one time she abandoned him he never try to harm her directly. Indeed, all Luna had to do was say she was sorry and Amok instantly forgave her.

    Other Third Earth Inhabitants 

The Nether-Witch

A mysterious being rumored to have ties to the other world. Spoken of in terms of fear and awe but believed to offer council and aid to those who seek her. One of the more interesting aliases of Mumm-Ra, as it is implied to have existed long before the Thundercats came to Third Earth, highlighting just how deceptive the devil-priest can be
Tropes Associated with The Nether-Witch
  • Dark Is Not Evil: While few would dare venture into her cave, she is still regarded as someone who can be sought for help. Lion-O is given exactly what he asked for without anything in return and is even warned of the consequences. Oddly, despite the revelation, there was no trickery involved in the deal, though it was hinted that an ancient sorcerer of good was deceived in this manner and banished to the astral plane to remove him as a potential rival
  • Hot Witch: Beauty with an elegant and formidable aura, befitting a sorceress of her reputation.
  • Mood Whiplash: Very soft spoken when describing how she can help and what it entails. Lion-O's mere attempt to discuss it is suddenly met with a violent, almost possessed, expression as she screams that the deal's terms are final if accepted, then reverting just as quickly to her previous calm demeanour.
