----
!!!''WesternAnimation/ThunderCats2011'' provides examples of the following tropes:

* PantheraAwesome: Lions and tigers and plenty of other big cats, oh my!
* ParentalFavoritism: Played with:
** To Tygra, Lion-O is the favorite, due being a less able warrior, immature and irresponsible, yet getting every advantage due to bloodlines.
** However, in Lion-O's eyes, Tygra is the favorite, being seen [[TheAce better than him at pretty much everything]] and more like the heir Claudus truly wanted.
* PendulumWar: Battles between Cats and Lizards are usually shown with the odds heavily weighted in favor of one side, only for the tide to turn dramatically in favor of the other.
* PerfectPacifistPeople: [[DeconstructedTrope Deconstructed]] with the Ro-Bear Berbils. A race of CuteMachines programmed as builders and helpers, their villagers are regularly abducted and enslaved by The Conquedor due to their inability to fight back. Panthro must [[TrainingThePeacefulVillagers train]] them to build a village defense system.
* PigMan: Encountered in the Swordsmans' Town, one a miserable failure at a sword contest, the other a crony of the Duelist.
* PlantAliens[=/=]PlantPeople: The Petalars
* PleaseSpareHimMyLiege: [[ReconstructedTrope Reconstructed]] when Lion-O doesn't so much plead for as ''demand'' the release of two stockaded Lizard prisoners whose lynching was narrowly avoided by Claudus' timely arrival. Though skeptical, Claudus takes Lion-O's SuddenPrincipledStand as an illustration of Lion-O's leadership, and pardons the Lizards.(Besides, he still has plenty in the dungeons.)
* PlotTailoredToTheParty: Features in "Journey to the Tower of Omens". To whit, [[spoiler:Snarf discovers the entrance to the dungeon by trying to eat some fruit from a tree. Getting past the first trap requires the Thunderkittens' lockpicking skills, the second, Cheetara's super-speed and extendable staff. Panthro's SuperDrowningSkills in a water trap leads him to find a way out and save the others, Lion-O is able to use Sight Beyond Sight to find a switch in a cliffside, which Tygra activates by hitting with his whip, thus opening the way to the Tower.]]
* {{Plunder}}:
** The Lizards loot Thundera, and the Thunderkittens, in turn, help themselves to their takings to acquire new clothes.
** Captain Tygus procures the Warstone for his Commander as spoils of war.
* PointyEars: The Cats, many of whom have ear placement and shape that is more Elfin than purely animal.
* PoliticallyIncorrectVillain: The Cats of Thundera. Alley Cats like beating and mugging hapless Dogs, and festival goers like yelling at beggar children and tormenting and lynching stockaded Lizards.
* PortalCut: [[spoiler: Panthro loses both arms when the portal to the Astral Plane collapses while he's holding Grune on the other side.]]
* PowderkegCrowd: At a festival, one of these merrily harasses and physically threatens a pair of stockaded Lizards, until Lion-O attempts to [[ShamingTheMob shame]] them out of doing so. Things go rapidly downhill from there.
* ThePowerOfLove[=/=]ThePowerOfHate: Explored from several angles in "The Curse of Ratilla."
* ThePowerOfFriendship: How loyal the Cats are to Lion-O influences if their eyes flash when he calls them. [[spoiler:Only Cheetara's glow so far.]]
* PowerOfTrust: Lion-O wins over [[spoiler:Viragor]] in "Forest of Magi Oar" by trusting in the Sword of Omen's judgement and tosses away his weapons as [[spoiler:Viragor]] charges him.
* PowerTrio: Lion-O, Tygra, and Cheetara are the base trio of the FiveManBand.
* PoweredByAForsakenChild:
** The Sword of Plun-Darr and its gauntlet were forged by the blood of a star which [[spoiler:had three planets filled with billions of people.]]
** In a surprising twist, [[spoiler: The Sword of Omens had this origin too, as the remnants of the material from that star]].
* PraetorianGuard: Jaga's Clerics are referred to as the Guardians of the Crown.
* PragmaticAdaptation: The two-part "The Trials of Lion-O" adapts [[WesternAnimation/ThunderCats the original series]]' five-episode Anointment Trials arc, where Lion-O earns the right to lead the [=ThunderCats=] by defeating each of them at what they're best at. Since the [[ContinuityReboot reboot]]'s twenty-four episode order and SternChase plot don't allow for the other Cats to challenge him, Lion-O's trials are incorporated as Spirit Stone-induced AdventuresInComaland where he's challenged by spirits in [[AFormYouAreComfortableWith the forms of his friends]], [[spoiler:for the right to come BackFromTheDead]].
* ProducePelting:
** In "Omens Part 1" Some boys do this to stockaded Lizards, only for Lion-O to shoo them away.
** In "Song of the Petalars" the Thunderkittens do this to [[SeeTheInvisible defeat]] Khamai's InvisibilityCloak.
* ThePromisedLand: The Garden is the ancestral home of the Petalars, which they've been separated from for generations, ever since a great wind blew them into the Briar Woods. They travel in search of The Cliff of Winds, a location in the woods that will mark the way back to the Garden.
* PropheciesAreAlwaysRight: So far, Jaga's allusions to to prophecy in the Book of Omens have been correct. It's [[FutureImperfect misremembering the past]] that gives the Cats trouble.
* ProphecyTwist: Ahmet warns Lion-O that he will ''feel'' betrayed by his brother as the evening bell tolls. In the Astral Plane, Tygra almost but not quite betrays Lion-O, seemingly proving the vision wrong. Then, just as the evening bell tolls... [[spoiler: Lion-O catches Tygra kissing Cheetara.]]
* ProtectivePressure: A tremendous amount is released when Grune forces open a door [[spoiler:to Mumm-Ra's suspended animation chamber]].
* ProudWarriorRace: The Cats... much [[FatalFlaw too proud]].
** Particular emphasis goes to the Tiger Clan, who refused to ask ''anyone'' for help curing a plague. As a result, [[spoiler: everyone died, and only a deal with demons made it possible for them to "Live"... but at the cost of turning into monsters every night, and technically being locked in a state between life and death.]]
* PsychicPowers: The Sword of Omens grants its user the power of "Sight Beyond Sight," both general {{clairvoyance}} and {{precognition}}.
* PunctuatedForEmphasis:
** In "Omens Part 1" During Lion-O's RiteOfPassage, Claudus delivers the bulk of his LectureAsExposition with the bellowing emphasis of a DrillSergeantNasty.
** "[[ByThePowerOfGrayskull Thunder... THUNDER... THUNDERCATS, HOOOOOOO!!!]]"
* PunctuatedPounding: "These bears *clang* are ''not'' *clang* your property!" (Cuts Conqedor's weapon in half)
** Claudus continues his lecture while sparring with Lion-O.
* PuppyLove: [[InvokedTrope Invoked]] in-universe with Tygra's quasi-courtship of Cheetara when they first meet as children.
* PutDownYourGunAndStepAway: In "Into the Astral Plane", Grune orders the [=ThunderCats=] to drop their weapons, or his troops will open fire on their Elephant hostages.
* PyrrhicVictory: Leo's rebellion against his Commander freed the enslaved Animals, but at the cost of the loss of their homes and great loss of life [[spoiler:as their ship crashes into Third Earth]].
** Referenced as exact words in "What Lies Above: Part 2" by Mumm-Ra: [[spoiler:Lion-O, the other cats, and [[TheCavalry all his allies]] have defeated him, Panthro manages to land the falling city mostly safely, and Lion-O has seen how many he has helped and how this inspires hope that all the races of Third Earth can finally unite to stop Mumm-Ra...but he escapes with the Tech Stone, and Pumyra is revealed as a traitor and goes off with him.]]
* TheQuest: Find {{MacGuffin}}s to facilitate BigBad Mumm-Ra's defeat.
* TheQuisling: [[spoiler:Pumyra is happy to sell out her entire race just to get petty revenge against Lion-O for letting her die without even knowing it.]]
** Vultaire, the leader of the birds allies with Mumm-Ra despite it being in the absolute [[ColonyDrop worst interests of his city]] and his people.
* RagnarokProofing: If LostTechnology is so lost, why does it look so brand spanking new?
* RagtagBunchOfMisfits: [[DiscussedTrope Discussed]]. Panthro views the [=ThunderCats=] as being this, and wonders how they got as far as they did without him.
* RainOfArrows: The Cats employ this tactic during The siege of Thundera.
* RapePillageAndBurn: Mercifully confined to the latter two, this being a children's show, the Lizards are shown sacking Thundera's smouldering ruins.
* RapidAging[=/=]WeAreAsMayflies: [[InvertedTrope Inverted]]: [[spoiler:The Petalars have incredibly brief lifespans compared to the Cats, only living for about a day before they wither away, but Cheetara points out that this is ''relative''. To a Petalar, that day is an incredibly rich, full lifetime.]]
* RatMen: Among the many animal races are sapient rats and mice.
* RearrangeTheSong: Though [[InstrumentalThemeTune lyricless]] and heavily [[TruncatedThemeTune truncated]], what remains of the ''WesternAnimation/ThunderCats'' theme (including its {{Fanfare}} and EpicRiff) has been given a dramatic OrchestralVersion, with an EtherealChoir voicing.
* ReallyDeadMontage: [[spoiler:The Petalar Emrick]]
* TheReasonYouSuckSpeech: Panthro delivers one to Grune in "Old Friends" that points out that Grune's treachery hasn't gotten him any closer to being king.
* RecycledInSpace: "Ramlak Rising" is ''Literature/MobyDick''... ON THIRD EARTH!
* RecycledTitle: Over 25 years later, it's still just ''[=ThunderCats=]''.
* RedOniBlueOni: In their better days, Grune is the deeply motivated, ambitious go-getter to Panthro's levelheaded, rational loyalist.
* RedSkyTakeWarning: Red swirling clouds and lightning mark Mumm-Ra's BigEntrance as he gears up for his first attack.
* ReimaginingTheArtifact: So, the enemies of the original ''WesternAnimation/ThunderCats'' were called "Mutants". That's surprisingly demonizing, actually, since they look beastly too, [[WhatMeasureIsANonHuman moreso than the heroes]]. The whole thing smacks of some kind of InternalizedCategorism or [[FantasticCasteSystem caste system]], FantasticRacism, even. Aren't they all just Animals? Well, ''yes.'' And so the worldbuilding begins...
* ReptilesAreAbhorrent: [[JustifiedTrope Justified]], while the Lizards are violent and aggressive, they're responding to generations of marginalization, oppression and enslavement fueled by the Cats' FantasticRacism.
** Later, many are shown to honestly not care at all about Mumm-Ra, and are willing to take up Lion-O's offer and simply leave his forces and return to their families.
* LaResistance: The Cats turned on their former commander [[spoiler: Mumm-Ra, striking up an alliance with the slave races they ruled over to mount a successful rebellion.]]
* TheReveal:
** Nobody can say they were not at least a ''little'' impressed by Mumm-Ra's entrance(s).
** The legitimately surprising MetaTwist [[spoiler:Jaga's survival of his HeroicSacrifice in "Omens Part 2"]]
** The [=ThunderCats=] and Mumm-Ra had an ancient connection that led to their current rivalry. The twist? [[spoiler:The space-faring [=ThunderCats=] were ''working'' for him. [[HeelFaceTurn Until they turned on him, anyway.]]]]
** [[spoiler:Pumyra was both [[DeadAllAlong Dead]] and EvilAllAlong, and is a [[SixthRangerTraitor traitor]] serving Mumm-Ra out of {{Revenge}}.]]
* RidiculouslyCuteCritter:
** The little Petalars
** The Robear-Berbils, which Panthro [[LampshadeHanging explicitly notes]] as a reason to distrust them.
*** Later, during a hunting trip, he dismisses Wilykit's claims that they can't kill an animal because it's cute, because "Those taste best."
** Baby Tygra. Sweet mother of cute, Baby Tygra.
* RidingIntoTheSunset: The Drifter gets to do this, finally becoming his [[TheDrifter archetype]] as he sets off to travel [[WanderingTheEarth from place to place]] [[spoiler: returning all the swords the Duelist took as trophies.]]
* RingOut: In Thundera's {{Fictional| Sport}} GladiatorGames, it serves as a VisualPun, as the tree that serves as the arena is surrounded by water... fairly humiliating, [[CatsHateWater for a Cat]].
* RightMakesMight: This is essentially how the stones of power work. The more righteous the wielder, the more power the stones will grant them. Lion-O and Leo are able to use their full power because they fight for the good of all the races. Claudus is able to use a lot of the sword's power because he fights to protect his people despite being a NobleBigot, but not to its full extent. The sword stays in its dagger form in Grune and Slithe's hands, and it outright electrocutes Mumm-Ra, who is evil to the core and believes MightMakesRight. Possibly subverted though, and Mumm-Ra believes he can force the stones' full power with his own immense magical strength.
** In "The Trials of Lion-O Part 2," Lion-O has to [[spoiler: get spirit!Panthro out of a ring within a time limit. Panthro's much too strong to be forced out, but Lion-O eventually realizes that [[LoopholeAbuse as his king, he can order Panthro to step out of the ring]].]]
* RiteOfPassage:
** Lion-O "fails" his test of kingship when he hides the fact that he's seen a vision in the Sword of Omens.
** The Petalars have one where they gather and sing when one of their number is born, or dies.
* RoarBeforeBeating:
** A lion's roar concludes the ThemeTune.
** Lion-O and Claudus tend to do this when angered, regardless of whether or not they manage to beat their attackers.
* RoaringRampageOfRescue: Claudus elects to DitchTheBodyguards to pursue Grune into TheThunderdome, where he holds a hostage [[spoiler:Claudus' friend, Panthro.]]
* RoboSpeak: As before, the Berbils.
* RockBeatsLaser: [[AvertedTrope Oh my, no...]] Magic does considerably better than [[MedievalStasis medieval weapons]] mind, but that just doesn't cut it against the full extent of the Lizards' LostTechnology SuperweaponSurprise.
* RocketPunch: The Berbil-upgraded Thundertank is armed with a pair.
* RoofHopping: Or rather, tree hopping, which Cats do for sport ([[InASingleBound to a fantastic degree]]) in Thundera's GladiatorGames.
* RoomFullOfCrazy: [[DownplayedTrope Downplayed]]. Lion-O covers the walls of his room with diagrams of his BlackBox acquisitions, much to Tygra's irritation.
* RousingSpeech:
** In "Omens Part 2" Claudus performs one to psych up his troops during TheSiege.
** In "Song of the Petalars" Lion-O performs one for the [=ThunderCats=] when he's decided to face down the entire Lizard army.
* RubberForeheadAliens: A few are scattered among the crowds of HumanoidAliens and PettingZooPeople in the Swordsmans' Town, the most notable being the Duelist.
* RummageFail: [[TheArtfulDodger Artful Dodger]] Wilykat has to try a few times before fishing coins out of a LowerClassLout's pocket, "Ewww, what does he keep in here?"
* RunOrDie:
** In "Omens Part 2" this prompts the [=ThunderCats=]' escape from TheSiege of Thundera, as Mumm-Ra, Grune and the Lizards' LostTechnology-fueled military might is too much for the city to withstand, much less a few protagonists.
** In "Song of the Petalars" Lion-O first wisely elects to retreat from the pursuing Lizard army, only to later confront them head on in a grief-fueled fit of HonorBeforeReason.
* RunningOnAllFours: Cat competitors run [[CatUpATree up a tree]] this way in Thundera's GladiatorGames.
* {{Samurai}}: The Wood Forgers.
* SandIsWater: The Sand Sea in "Ramlak Rising," a literal sand ''ocean'' with waves, storms, sea monsters and pirate ships, that has islands of ''water.'' Landlubbers are screwed either way.
* SceneryGorn: "Ramlak Rising"'s opening scene, a leisurely look at the ruins of Thundera.
* SceneryPorn: Lots of it! Detailed (and spoiled) [[http://tv.ign.com/articles/117/1178363p1.html here]].
* SchematizedProp:
** Seen in the show's model sheets [[http://tv.ign.com/dor/objects/76335/thundercats/images/thundercats-20110630021525681.html here, for example]].
** In-universe, Lion-O actually makes an effort to diagram the BlackBox he purchased from his FriendInTheBlackMarket.
* SchizoTech: Once technology's reality is established, it's a total free-for-all based on RuleOfCool. Standard {{Ray Gun}}s? Got 'em. Flying SteamPunk pirate ships? Fair game. {{Futuristic Pyramid}}s with TronLines? Fits right in.
* SchmuckBait:
** "Ramlak Rising" The [=ThunderCats=] find ''[[LiteralMetaphor food]].'' Just floating on the surface of the [[SandIsWater Sand Sea]]. They're ''really'' hungry.
** "Journey To the Tower of Omens" The Thunderkittens see ''[[StickyFingers gold]]'' in a TempleOfDoom!
* ScrewThisImOuttaHere: The Lizard army has so little loyalty to Mumm-Ra -- not that he deserves any since he doesn't care one bit for them -- that squads are all too willing to accept Lion-O's offer of co-existence and abandon Mumm-Ra to go back to their homes.
** Later, in "The Curse of Ratilla," [[spoiler: Ratar-O's servant Mordrax gets rather fed up with his [[BadBoss master's frequent abuse]], and turns on him at the episode's climax by giving an unarmed Lion-O his weapons. ]]
* ScrewYouElves: In "What Lies Above, Part 1," Tygra doesn't take kindly to bird prefect Vultaire's haughty air of superiority. Rather than [[CantArgueWithElves argue with Vultaire]], Tygra tells Vultaire to shut up and tries to take him down a peg in a air race.
** In the first two episodes, the Lizards get a pretty good one in on the cats, who kept them as slaves, by utterly obliterating Thundera with mecha-tanks, missiles, and projectile weapons... while the cats, who were so convinced of their superiority, only have small amounts of magic, physical strength, and medieval-era weapons. As one lizard put it, they (the cats) went from the dominant race to an endangered species in a single day.
* SealedCastInAMultipack: This is how the Cats arrive on Earth.
* SecretTestOfCharacter: Turns out [[spoiler: the final test in Lion-Os trials was this.]]
* SeeTheInvisible: In "Song of the Petalars," Khamai's InvisibilityCloak is thwarted by the Thunderkittens' ProducePelting.
* SetBonus: The [=ThunderCats=] and their ArchEnemy Mumm-Ra hunt for various {{Power Crystal}}s, one of which is the Cats' own AmuletOfConcentratedAwesome, the Eye of Thundera in the Sword of Omens' hilt. If the others are placed in an accompanying gauntlet, their shared wielder will be rendered nigh omnipotent.
* ShadesOfConflict: White and Grey vs. Grey and Black. Well-intentioned [=ThunderCats=] Lion-O, Cheetara and Jaga work with grey-shaded pickpockets the Thunderkittens, hardened cynic Panthro, and {{Noble Bigot}}s Claudus and Tygra; and all come from a [[FantasticCasteSystem classist]], [[FantasticRacism racist]] culture. EvilOverlord Mumm-Ra has SelfishEvil [[TheDragon Dragon]] Grune, while the Lizard army is reacting to generations of the Cats' oppression, and its General Slithe has internalized the CycleOfRevenge.
* ShamingTheMob: [[InvertedTrope Inverted]]. Lion-O ''attempts'' this with a PowderkegCrowd harassing stockaded Lizard scavengers, but his assertion that "they don't deserve this" is interpreted as a call for a VigilanteExecution, ''creating'' an AngryMob. Lion-O's left with no choice but to demand they GoThroughMe.
* ShiningCity: Thundera, in the EpicTrackingShot and the subsequent EstablishingShot... until the downward {{tilt}} reveals the [[UrbanSegregation slums below]].
* ShipTease: Lion-O has had several with Cheetara, but now there's the matter of Tygra's attraction...
** [[spoiler: ShipSinking: Though it keeps to the mythos with Cheetara ending up with Tygra.]]
** As of her ''second episode'' [[spoiler: Pumyra starts flirting with Lion-O, who is just plain confused.]] And the episodes following it throw in a lovely dose of BelligerentSexualTension, culminating in [[spoiler: a SmoochOfVictory ]] in "Recipe for Disaster."
*** [[spoiler:ShipSinking: Yes, ''again''. She's actually a SixthRangerTraitor loyal to Mumm-ra.]]
* ShooOutTheClowns: In the "Curse of Ratilla" which dealt with slavery and many deaths of the slaves, Kit and Kat were not to be found.
* ShootTheRope: Tygra uses his new RayGun to shoot the wrappings binding Jaga.
* ShortRunInPeru: Ireland began airing new episodes while the series was still on hiatus in America.
* ShouldersOfDoom: All Clerics wear huge, white, rounded pauldrons on their {{All Encompassing Mantle}}s.
* ShoutOut:
** When Wilykit and Kat [[http://s3.amazonaws.com/kym-assets/photos/images/newsfeed/000/158/713/I%20nom%20mah%20fud.gif?1312619385 eat]] dinner they loudly munch "[[LOLCats OM NOM NOM NOM!]]"
** The Thundertank looks an awful lot like [[Franchise/{{Batman}} the Batmobile]].
** Tygra kicks Lion-O into a [[ThreeHundred seemingly bottomless well]].
** Mumm-Ra's ElectricTorture of Lion-O is straight out of ''Film/ReturnOfTheJedi''.
** Tygus is wearing a ''Anime/DragonBallZ''-style scouter.
** Leo's mane heavily resembles the hairstyle of one [[VideoGame/TalesOfTheAbyss Asch the Bloody]] [[spoiler:himself a ReverseMole]].
** A suit of armor appears that strongly resembles the gold cloth of lion of ''Manga/SaintSeiya''
** The sword competition Lion-O participates in is suspiciously like the [[TheDarkCrystal Trial By Stone]]
** "Come on beast! [[Literature/MobyDick For Hate's sake I spit my last breath at thee]]!"
** Per WordOfGod, Mumm-Ra's gauntlet is a nod to ''ComicBook/TheInfinityGauntlet''.
** The motorcycles in "Sight Beyond Sight" look suspiciously similar to the original ''Film/{{TRON}}'' lightcycles.
** The magic words to use the forever bag seem to be [[RankinBassProductions Rankin-Bass]].
** In "Recipe for Disaster", when fighting Mumm-Ra's giant dragon beast, Lion-O does the classic somersault animation sequence showcased at the end of the 1980s intro.
** In "Recipe for Disaster" Mumm-Ra manages to transform himself into a [[Franchise/{{Godzilla}} giant energy blasting lizard]] that is defeated by [[{{Mothra}} a giant benevolent butterfly with magic wings.]]
** In "Recipe for Disaster" Mumm-Ra uses the bones of a Sycorax, an ancient powerful being. Is the creature a beast of [[Theatre/TheTempest another powerful magic user]] or [[Recap/DoctorWho2005CSTheChristmasInvasion another alien entity?]] [[OneOfUs Knowing the crew in charge]] [[TakeAThirdOption it's entirely possible that it's]] ''[[TakeAThirdOption both.]]''
** In "The Soul Sever", Tygra's robotic body looks suspiciously like a certain [[Franchise/{{Transformers}} Autobot leader.]] And its final form is basically a mechanical version of Creator/JeffGoldblum's TheFly in his final form.
** In the same episode, Soul Sever himself is trying to revive his dead family's souls in mechanical bodies like his. This is all fine and dandy until you realize he's voiced by Creator/JeffreyCombs of ''Film/ReAnimator'' fame.
** Another reference has Soul Sever briefly turn on a vision mode that scans body heat with a blue background, as well including faint sound resembling a heartbeat when it is on,very similar to The Franchise/{{Predator}}'s mask vision.
** In "What Lies Above", the scene where the Cats first enter Avista City is higly reminiscant of the ''Millenium Falcon's'' arrival in [[TheEmpireStrikesBack Cloud City]]. Including the music during their first walk through this City in the Clouds.
** "Native Son" is centered around people who refused to side with the good guys during an ancient war, were exiled into a remote place, and [[spoiler:died out with a dark curse hanging over them]]. Well, let's hope they come back, [[LordOfTheRings swarming over the enemy as ghosts]]
** Cheetara says "[[SonicX Gotta go fast!]]" before dashing through a hall of blades.
* ShrineToTheFallen: During Grune's homecoming festival, Panthro's painted portrait and a stand holding his nunchucks receive a place of honor at the royal family's banquet table in their [[TheThunderdome amphitheatre]].
** Wilykit and Wilykat's father gets a portrait drawn by his children hung up in the family home after his death.
* SiblingRivalry: Lion-O suffered from cultural ostracism and is jealous of the success and favoritism adoptive older brother Tygra enjoyed both with their people and their father. Tygra sees Lion-O as a {{Cloudcuckoolander}} and JustAKid and resents Lion-O's right of succession by [[RoyalBlood bloodline]]. Then there's the fact that they both like the same woman...
* SiblingTeam: There are two sets in the series: brothers Lion-O and Tygra and the twins Wilykit and Wilykat.
* SiblingTriangle: About the ''only'' interest Lion-O and Tygra share is their attraction to Cheetara. {{Foreshadowing}} implies that Tygra may betray him because of it.
** [[spoiler:Subverted. Tygra doesn't necessarily betray Lion-O but he ''DOES'' end up with Cheetara, which, for Lion-O, is probably just as bad.]]
* TheSiege: In "Omens Part 2" Slithe and the Lizards launch a devastating attack against Thundera, breaking out multiple [[ForgottenSuperweapon Forgotten]] {{Superweapon Surprise}}s as a HigherTechSpecies with a {{Turncoat}} Grune and TheDreaded Mumm-Ra bolstering their ranks and spearheading the final stages. It's a CurbStompBattle. Thundera doesn't even [[AllYourBaseAreBelongToUs stand a chance]].
* SimpleStaff: The Clerics' main weapon. (with the exeption of head cleric Jaga's [[StaffOfAuthority crosier]])
* SlaveCollar: Present on the [[WorkingOnTheChainGang chain gang]] of Lizard slaves forced to haul Grune and his giant geode since he's TooImportantToWalk.
* SlaveLiberation:
** In "Omens Part 1," Lion-O successfully pulls a PleaseSpareHimMyLiege, securing the release of two Lizard scavengers.
** In "Legacy," LaResistance [[spoiler:allies with the slaves under their command to rebel against Mumm-Ra.]]
** In "The Curse of Ratilla," the heroes go after Ratar-O's mining operation to free his Thunderan prisoners.
* SlaveRace:
** In "Omens Part 1" any Lizard scavengers caught by the Cats are taken as prisoners of war and MadeASlave. Dozens of these arrive chained and hauling Grune and his geode. [[DeliberateValuesDissonance No one sees anything wrong with this]].
** In "Legacy" which reveals the historical context of Mumm-Ra's vendetta against the Cats, we see Mumm-Ra has [[spoiler:made slaves out of all Animals ''except'' the Cats, who are "loyal" servants under his command.]]
* SleepCute: Tygra and Cheetara in "Berbils", much to Lion-O's annoyance.
* SlidingScaleOfAnthropomorphism: The Cats run the gamut between BeastFolk and PettingZooPeople. This relative variance is itself the ''basis'' of their FantasticCasteSystem, with tailless BeastFolk as nobles. Most other races on Third Earth are PettingZooPeople or lower, which also serves as a pretext for the Cats' FantasticRacism.
* SlowMotionFall: After his stabbing, Claudus falls from the top of the TheThunderdome's tree into the water below.
* SmallSecludedWorld: Thundera, thanks to its cultural dominance, insular nature and WallAroundTheWorld.
* SmoochOfVictory: Cheetara's FirstKiss [[spoiler: with Tygra]], is this, a thank you and reward for his help as well as a RelationshipUpgrade.
** In "Recipe for Disaster," Lion-O gets one of these courtesy of [[spoiler: Pumyra, whom he just saved from Mumm-Ra]].
* SoftWater: The water surrounding the tree in Thundera's amphitheatre is a very long drop from the tree's apex, yet the fall itself doesn't kill any competitors or Claudus.
* SoiledCityOnAHill: Thundera, corrupted by the Cats' own bigotry and {{Pride}}, and destroyed by the Lizards in retaliation for generations of oppression.
* SomedayThisWillComeInHandy: [[DiscussedTrope Discussed]]. After discovering the purpose and interface of his BlackBox, Lion-O reflects that the effort he put in and all he's gone through for the sake of his ChekhovsHobby "is finally going to pay off."
* SoulJar: [[spoiler:Mumm-Ra [[YourSoulIsMine imprisons]] Jaga inside a magical lantern that forces him to serve as a beacon to the Book of Omens.]] Afterwards, [[spoiler:Jaga's soul takes residence in the Book itself.]]
* SpaceAmish: [[DeconstructedTrope Deconstructed]]. The Cats fancy themselves the keepers of a "fragile peace" in a "world of warring Animals" but their lack of technology utterly undoes them.
* SpaceElves: The Cats: Type 1: Elves in Space.
* SpaceRomans: The Cats wear no togas, but they are a ProudWarriorRace that has lavish BloodSport spectacles and extravagant feasts in a [[TheThunderdome huge amphitheatre]] and take conquered [[SlaveRace races]] as slaves. And of course, they do love themselves some Lions... Everyone's armor even has a six-pack like the articulated armor of Roman Legionnaires.
* SpeedBlitz: A tactic of the Clerics, who have the gift of SuperSpeed.
* TheSphinx: Part of Thundera's [[BrightCastle Bright]], BigFancyCastle, wearing a huge red cabochon ChestInsignia. It's [[MonumentalDamage decapitated]] after TheSiege.
* SpikesOfDoom: In a TempleOfDoom, they sit below a narrow walkway that ends in a LockAndKeyPuzzle with hundreds of keys suspended from the ceiling. If the wrong key is used...
* SpotlightStealingSquad: Lion-O has received the [[{{Pun}} lion's share]] of CharacterDevelopment so far.
* SssssnakeTalk: Present with the Lizards, but comparatively [[DownplayedTrope underplayed]]. They stress their sibilants (the "s" sounds), but don't heavily prolong them.
* StabTheSky: Done during Lion-O's BattleCry.
* StairwellChase: In "Journey to the Tower of Omens" the Cats and Mumm-Ra race to the tower's top to get the Book of Omens.
* StarfishAliens: In "Journey To the Tower of Omens" [[spoiler: Captain Tygus is shown stealing the Warstone from a red planet populated with these.]]
* StaringThroughTheSword: The method by which Lion-O receives his vision from the Sword of Omens.
* StartsWithTheirFuneral: "Ramlak Rising" opens with Claudus VikingFuneral.
* StatingTheSimpleSolution: LockAndKeyPuzzle with [[NeedleInAStackOfNeedles hundreds of keys]] in a TempleOfDoom? "Leave this to the masters!"
-->'''Wilykit''': Why waste time picking out a key?
-->'''Wilykat''': When you [[spoiler:could just pick the lock]]?
* SternChase: The [=ThunderCats=] are always pursued to some degree, but the Lizards are hot on their heels in "Song of the Petalars," prompting Lion-O to order his followers to flee into [[TheLostWoods the Briar Woods]].
* [[spoiler:StickyBomb]]: What Lion-O's BlackBox turns out to be, a real GrailInTheGarbage, which he uses to save Claudus and Tygra during TheSiege.
* StockFootage: During TheSiege of Thundera, the same "arrows fly, Lizards shot at, Lizards run" sequence was used at least twice, quite close together, which is particularly jarring. The InternalHomage to "[=ThunderCats=] HO!" has already been reused, even in an area with no cliff.
** Mostly averted with Mumm-Ra's TransformationSequence, however: as of May 12, 2012, Mumm-Ra has transformed four times on-screen, and three different sequences have been used.
* StockPunishment: PlayedForDrama. Two Lizard scavengers are stuck in stockades, and they don't just suffer ProducePelting from those who have ComeToGawk, but physical threats by a PowderkegCrowd, who rapidly get out the TorchesAndPitchforks and demand a VigilanteExecution.
* StockScream: One of the sailors in "Ramlak Rising" does a Wilhelm scream when dragged overboard by the Ramlak.
* StockSoundEffects:
** The Berbils make little squeaky toy sounds when they bounce.
** Eating Candyfruit causes Wilykit and Kat to go hyperactive with a little video game power-up sound.
* SuddenPrincipledStand: Lion-O makes one when he tries ShamingTheMob harassing the stockaded Lizards and demands his father PleaseSpareHimMyLiege. It pays off when his father grants them pardons, though his people brand him a CategoryTraitor and a ZombieAdvocate, and his father considers him an UnwittingInstigatorOfDoom when the Lizards invade the next day.
* SugarBowl: The Ro-Bear Berbil tribe initially seem to live in one, complete with color-saturated pastoral scenery and ultra-cute inhabitants. [[OhCrap Then the slavers turn up...]]
* SuperweaponSurprise: Bigger Brothers subtype. The Lizards, a newly HigherTechSpecies, have LostTechnology galore and conceal their benefactors, {{Turncoat}} General Grune and Mumm-Ra, TheDreaded ancient enemy of the [=ThunderCats=], within their ranks to spearhead the final stages of TheSiege of Thundera.
* SuspiciouslySimilarSong: Kevin Kliesch has been pretty upfront about getting inspiration for the shows soundtrack from ''Franchise/StarWars'' and ''Film/TheLordOfTheRings''. The lullaby Wilykit plays on her flute in particular is inspired from a piece in ''Film/ReturnOfTheJedi''.
* SwirlingDust: The first indicator of the Clerics' SuperSpeed DynamicEntry.
* SwordAlmighty: Even given the prevalence of LostTechnology, the Sword of Omens is a legendary weapon.
* SwordBeam: The Sword of Omens can shoot an energy bolt for its chosen wielder, by pointing it at the intended target and screaming "Hooo!"
* SwordFight: Several, naturally.
** In "Omens Part One" King Claudus has a sword fight with Lion-O to show off the Sword of Omens' power.
** In "Legacy", Leo has a sword fight against his commander, both using their respective {{Cool Sword}}s.
** In "The Duelist and the Drifter" there are multiple fights against MasterSwordsman The Duelist.
** In "Between Brothers" Lion-O and Tygra have a sword fight both using the Sword of Omens, one the real version, one created in the astral plane.
** In "Birth of the Blades," Lion-O and Mumm-Ra engage in a brief duel between the latter's use of [[SwordBeam Sword Beams]] via his evil magic.
** In "What Lies Above: Part 2," Lion-O and Mumm-Ra have another duel before [[spoiler:Pumyra betrays them]] and Mumm-Ra is driven off by the arrival of TheCavalry.
* SwordSparks: Frequent, lightning-like arcing and sparking when the Sword of Omens strikes a target.
* SympathyForTheDevil: Lion-O finds himself affected by a Lizard prisoner's ScrewYouElves speech, enough to make a SuddenPrincipledStand, and try ShamingTheMob harassing them, successfully [[PleaseSpareHimMyLiege arguing with his father]] for their pardon and release.
