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

* FacelessEye: The Eye of Thundera lives up to its name; the red cabochon develops a glowing white slitted pupil when it sends a vision through the Sword of Omens, and is [[UnreliableIllustrator sometimes]] depicted with a black [[http://en.wikipedia.org/wiki/Chatoyancy chatoyancy]] in its resting state.
* FacePalm: Lion-O at Tygra's actions after he [[spoiler: accidentally drank a love potion meant for Pumyra]].
** Panthro's frequent reaction to the antics of his teenaged companions. "Oh brother!"
* FacialMarkings: Used with the Cats to highlight their eyes, cheekbones and jaws.
* FalseFriend: [[spoiler: Pumyra.]]
* FalseReassurance: Mumm-Ra [[spoiler:(speaking to Jaga)]] "Come now, don't be ''afraid''".
* FamedInStory[=/=]ShroudedInMyth: The Sword of Omens, The Eye of Thundera, The Book of Omens, Mumm-Ra and LostTechnology all play important parts in Thunderian legend, but their history is so ancient that Thundera has inevitably forgotten parts of it, and remain skeptical or dismissive of others.
* FamilyFriendlyFirearms: Lasers, lasers everywhere!
* {{Fanfare}}: Kept, along with the EpicRiff in the TruncatedThemeTune.
* {{Fanservice}}: Much of the officially released concept art and character sheets feature main characters in various states of dress and undress. Since the pilot of the original series had all of the leads stark naked, this may be a nod to tradition.
** It extends even further in the animation itself,. "Recipe for Disaster" has two scenes that are lifted directly from the opening of the 1985 series.
* FantasticCasteSystem: [[http://crewofomens.tumblr.com/post/8435103220/i-first-saw-thundercats-on-toonami-when-i-was-young Word of God]] splits Thundera's Cats into two types. Those without tails are society's elite, while those with tails are consigned to a life of poverty [[UrbanSegregation in the slums]]. The Thunderkittens, who have tails, are introduced as pickpockets on the streets. Among the tailless, the line of royal succession is reserved for Lions like Claudus and Lion-O.
* FantasticDrug: Played with the Ro-Bear's Candy Fruit. It's tasty, nutritive... and made of pure sugar. Wilykit and Wilykat quickly become hooked to it and for all means and effects, they behave as if they were eating a cocaine/amphetamine combo. Both purposely get high on Candy Fruit to achieve CaffeineBulletTime.
* FantasticGhetto: Thundera's slums. This is where the caudate Cats and specific minorities like Dogs must live. The Thunderkittens have a hovel on the WrongSideOfTheTracks, while Lion-O braves muggers in TheCityNarrows to shop for LostTechnology in the BlackMarket.
* FantasticRacism: By way of AnimalJingoism. A hapless Dog is beaten and mugged by vicious Alley Cats in the slums. At a large festival, Lion-O very narrowly averts a public lynching of two stockaded Lizards, who the Cats enslaved for the crime of petty theft.
** In "The Pit", the Dogs don't think very highly of Cats, believing them to be disloyal creatures. [[spoiler:Pumyra's and Lion-O's display of loyalty to each other during their match earns the entire crowd's adulation.]]
** In the flashback in "Birth of the Blades", Mumm-Ra displays plenty of this in regards to the Cats and the Lizards. He makes disparaging remarks about the Cats' intelligence right to Leo's face and treats the Lizards as cannon fodder.
* FantasyKitchenSink: Stuffed to brimming.
* AFeteWorseThanDeath: The AngryMob of Thunderian townspeople thinks it'd be fun to cap off Grune's homecoming festival with a bit of Lizard lynching. Lion-O and the Lizards aren't so keen on the idea.
* FeudalFuture: Thundera is stuck in MedievalStasis with a dash of magic and technology for spice.
* FictionalSport: "[[GladiatorGames The Games]]" in Thundera's [[TheThunderdome Thunderdome]]: A racing ChaseFight between two Cat competitors climbing, swinging, jumping and running up a tree to to ring a bell at its top, [[BloodSport violent]] kicking and punching included. RingOut involves knocking a player off the tree into a pool of water.
* FightingTheLancer: The frequent manifestation of Lion-O's SiblingRivalry with Tygra. Feeling testy over Tygra's petty insults, Lion-O challenges him to a match of Thundera's ChaseFight GladiatorGames, hoping to embarrass him in front of Grune. Lion-O is defeated soundly, and publicly humiliated. Otherwise, they tend to engage in back-and-forth sniping, like arguing over whether to retreat from the Lizard army.
** "Between Brothers"
* FinalExamBoss: Lion-O uses the lessons he learned in his Trials to save the Cats in the 16th episode.
* FindersRulers: 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''.
* FinishingStomp: A Lizard punctuates dragging a captive Jaga before Mumm-Ra with a prehensile foot stomp to his head.
* FirstKiss: In "Between Brothers" Cheetara initiates a long-delayed one [[spoiler:with Tygra]] to [[SmoochOfVictory thank him]] for his help and cement their RelationshipUpgrade.
* FishPeople: The Fishmen from "Ramlak Rising".
* FiveManBand: But of course.
** TheHero: Lion-O
** TheLancer: Tygra
** TheChick[=/=]ActionGirl: Cheetara
** TheBigGuy[=/=]TheSmartGuy: Panthro
** TagalongKid: Wilykat and Wilykit
** SixthRanger: Pumyra
*** [[spoiler: Make that SixthRangerTraitor, thanks to being Mumm-Ra's servant and [[TheMole spy]] [[EvilAllAlong all along.]]]]
** TeamPet: Snarf
* FoolishSiblingResponsibleSibling:
** [[InvertedTrope Inverted]]. Tygra is TheDutifulSon to Lion-O's {{Cloudcuckoolander}}, but Lion-O's realization that MySpeciesDothProtestTooMuch and interest in LostTechnology turn their dynamic on its ear when he's proven right.
** Later played straight when Tygra proposes taking on the Thunderkittens and a bloodyminded Lion-O first rejects them out-of-hand.
** Inverted again when Tygra unsuccessfully tries to pressure Lion-O to meet the entire Lizard army head on, like their father [[HonorBeforeReason would have wanted]].
* ForDoomTheBellTolls: When Tygra beats Lion-O to the bell in their racing game, Lion-O hears the ominous sound of his reputation taking a further hit, along with his brother's gloating and the crowd's cheers.
** Much more literally in "The Trials of Lion-O, Part 2," where it means [[spoiler: Lion-O has failed the trials and is going to stay dead]].
* ForeignQueasine: No surprise that the birds of Avista City would enjoy eating live food, insects, and other things that made haggis look like fine dining. Fortunately, Wily Kit and Kat and their [[BagofHolding Forever Bag]] had just the answer.
* ForgetfulJones: A species-wide attribute of the Elephants, all very forgetful and absent-minded.
* {{Forgiveness}}: Allows Tygra to [[spoiler:release his biological clan from a curse of undeath]].
* ForgottenSuperweapon: LostTechnology. All of it. And [[SuperweaponSurprise surprise]], the Lizards have it. Including [[spoiler:missile-launching Walking Tanks.]]
* AFormYouAreComfortableWith: [[spoiler: The Copy!Wilykit says this verbatim during Lion-Os test]]
* FriendInTheBlackMarket: Jorma, with whom Lion-O has an apparently longstanding relationship.
* FriendOrIdolDecision: In "Birth of the Blades", Mumm-Ra forces Lion-O to choose between [[spoiler:Pumyra and the Sword of Plundaar. Lion-O chooses Pumyra, shifting the balance of the war in Mumm-Ra's favor but also proving to Pumyra that he is a king worth following.]]
** Though considering the latest [[EvilAllAlong reveal]], any acceptance of such proof was surely only a [[TheMole subterfuge]] to inspire trust.
* FriendsAllAlong: [[spoiler: Panthro and Dobo]]
* FromBadToWorse: In the two minute short, "Snarf: Butterfly Blues," Snarf's life gets difficult the very second after an infant Lion-O sees a butterfly.
* FullBodyDisguise: Excepting Jaga himself, all his Clerics wear {{All Encompassing Mantle}}s and helms with full hood and veil attached. Only their eyes are visible, the better to serve as PraetorianGuard.
* FurIsSkin: [[PlayingWithATrope Played with]]. Though all [=ThunderCats=] have FacialMarkings, all save Tigers have significantly different coloring for their "skin" than they do for their "hair," particularly in the case of Panthro's blue-grey FurryBaldness as offset by his jet-black muttonchops.
* FurryDenial: In the episode ''The Soul Sever,'' Lion-O claims that the technology that the Sever is using stripped him of his humanity... despite ''neither'' of them being human, not even before Sever's transformation. In fact, there appear to be no humans anywhere on Third Earth, so Lion-O's line is particularly confusing.
* FurryReminder: Real animal growls, whines and hisses are used to punctuate when the Animals of Third Earth are feeling emotionally agitated.
* FutileHandReach: Lion-O does this when Claudus is stabbed.
* FutureImperfect: Cheetara relates an oral history of the supposed creation of the Book of Omens. It is ''remarkably'' off-base, suggesting that even members of the AncientTradition like herself don't know the whole story.
* FuturisticPyramid: The base of Mumm-Ra's operations and his former prison.
* GallowsHumor: Three doozies from episode 18, the first two one right after the other. All ''from children''.
-->'''Wilykat:''' Snarf! That was all the food we had left!\\
'''Wilykit:''' Now we're doooomed!\\
'''Cheetara:''' Aren't you two being a little dramatic?\\
'''Wilykat:''' Dramatic? What if they never come back? What if we starve to death?\\
'''Wilykit:''' What if we have no food and we have to choose who gets eaten?\\
...\\
'''Panthro:''' You know what? It's about time you two learned some hard life lessons!\\
'''Wilykat:''' He's gonna kill us!\\
'''Wilykit:''' I told you he would!\\
...\\
'''Cheetara:''' *breaks a branch over her knee, tossing the two resulting sharp pieces of wood between the two of them* No more games, you two.\\
'''Wilykat:''' ...I think they want us to fight to the death.
* GardenGarment: The Petalars.
* GenreBlindness: The [=ThunderCats=] find a locked door at the end of a narrow walkway over a pit of spikes with numerous keys available, [[spoiler:and they don't think the wrong key will trigger a BoobyTrap?]]
* GettingCrapPastTheRadar: When the Thunderkittens interrupt Cheetara trying to help Lion use Sight Beyond Sight with a HandsOnApproach, we get this little exchange:
-->'''Wilykat''': Whatcha doin'?
-->'''Wilykit''': Ooh, I know what they were doing! [makes kissing noises]
-->'''Lion-O''': NO. We were... just... trying to get my sword to work...
** In Episode 14 "New Alliances," we get this little gem:
--->'''Cheetara''': That reminds me: thanks for watching my back. [kiss]
--->'''Tygra''': Well, your... back's real easy to watch.
*** Please note, this was the first episode to air in the [[SaturdayMorningCartoon new time slot]] traditionally reserved for younger demographics.
*** Also provides an in-universe example of the trope, as the Thunder-Kittens are standing ''right there'' during the exchange, and completely miss the innuendo. As a pair of 8-year-olds, they react [[AllergicToLove accordingly]]. [[GirlsHaveCooties Especially Wilykat]].
** In Episode 20, "Curse of Ratilla", Tygra and Cheetara are caught in a cave-in. Convinced they're going to die, they kiss. In the next scene, the cave-in stops.
---> '''Cheetara''': I think we just got lucky\\
'''Tygra''': *big grin on his face* Yeah, we did!
* GhibliHills: Surrounds the kingdom proper in the EpicTrackingShot that introduces Thundera.
* GiantFlyer: [[PrettyButterflies Lucy]]
* GiantSpider: [[ExactlyWhatItSaysOnTheTin Spidera]].
-->'''Wilykat''': [[AllMythsAreTrue I thought that was a myth]]!\\
'''Panthro''': [[OhCrap So did we]].
* GiantSquid: A HybridMonster, the Ramlak moves this way, ship crushing tentacle-vines included.
* GirlsHaveCooties: Wilykat upon seeing Tygra and Cheetara.
* GivingTheSwordToANoob: Claudus' reaction to Lion-O's failure of his RiteOfPassage. "The Sword is ready, Lion-O, but [[YouAreNotReady you are not]]." [[SubvertedTrope Subverted]] in that Lion-O ''passed'' his test, and was granted a vision by the Sword of Omens, but lied out of fear and ignorance of its significance.
* GladYouThoughtOfIt: Jaga pulls one of these, carefully cloaking references to "[[{{Precognition}} Sight Beyond Sight]]" in aphorisms about kingly behavior, to coax Lion-O into admitting he's had a vision. Unfortunately, he decides that having won Lion-O's trust, the details can wait...
* GladiatorGames: [[DownplayedTrope Downplayed]]. Though Thundera's "[[FictionalSport games]]" have all the violent, decadant trappings of an AncientGrome BloodSport, including TheThunderdome and [[http://dingo107.deviantart.com/gallery/?offset=24#/d4sysfq gladiator]] competitors, participation appears voluntary and nonlethal, as Lion-O and Tygra decide to compete in them on a whim.
* GlamourFailure: [[InvertedTrope Inverted]]. When a disguised Mumm-Ra's voice creepily bleeds through his facade as a VoiceOfTheLegion, it's implied he's simply doing it to [[EvilGloating gloat]] and show off.
* GoThroughMe: [[InvertedTrope Inverted]] as Lion-O interposes himself between two stockaded Lizards and an AngryMob in the mood for a VigilanteExecution.
* GondorCallsForAid: In the first season finale, Kit and Kat travel to most of those who they helped through their journeys to call for help. As the other [=ThunderCats=] stare down Mumm-Ra and [[spoiler:Pumyra]] Kit and Kat reveal [[spoiler:one Fishman.]] Looking worried, the Kittens then pull out [[spoiler:the Forever Bag and call forth all the other allies inside the bag.]]
* GoldenAge: "These were days of peace and prosperity on Third Earth..."
* GottaCatchEmAll: [[spoiler:According to an interview shown on Cartoon Network, the story will center around power stones that the group must gather, the Eye of Thundera being only one of them.]]
* GrailInTheGarbage: The BlackBox Lion-O purchases in Thundera's BlackMarket comes in handy later, when he witnesses how it might be used, and later employs it during TheSiege of Thundera [[spoiler: to blow up a War Mech.]]
* GrandStaircaseEntrance: Unusually PlayedForDrama (and horror) Mumm-Ra's ''second'' reveal, in {{flashback}}, has him slowly descending a stair, wheezing and shuffling and looking no less disturbing for his infirmity, again backed by his personal {{Leitmotif}} and ConLang OminousLatinChanting.
* GraveRobbing: The [=ThunderCats=] perform a heroic variant, since the Book of Omens is kept in the Tower of Omens, which served as the final resting place for the Clerics who transported it there.
* GreatBigBookOfEverything: The legendary Book of Omens, both an ancient history of Thundera and a [[TomesOfProphecyAndFate Tome of Prophecy and Fate]], assumed lost. Generals Panthro and Grune mounted a futile search, but during TheSiege of Thundera, Jaga informs Lion-O that it exists, and sends him racing to find it before Mumm-Ra does.
* GreatOffscreenWar: Beyond the conflict with the Lizards, the inferred historical conflicts that "brought law and order to a world of warring animals."
* GreenAesop: "The Forest of Magi Oar" has "There's no justification for disrupting ecology with rampant industrialization."
* GunshipRescue: [[spoiler: Panthro's DynamicEntry in the Thundertank, saving the other [=ThunderCats=] when they're surrounded by Lizards.]]
** Happens again in [[spoiler: "Into the Astral Plane," when Tygra uses the Thundertank to save the day when Grune orders his troops to open fire on the [[PutDownYourGunAndStepAway disarmed]] [=ThunderCats=].]]
** Once AGAIN in "New Alliances" when Panthro saves the other three from Sslithe, Addicus, and Kaynar [[spoiler: in a newly-upgraded, much bigger version of the Thundertank.]]
* HalfTruth:
** Jaga's OpeningMonologue neglects to mention that Third Earth's "peace and prosperity" belongs to the upperclass Cats, or that the ruler's "just heart" does not extend to other species.
** Grune pulls a doozy in his DeathNotification, particularly when he notes "It is only through [Panthro's] sacrifice I stand before you today."
* HammyHerald: In disguise, Mumm-Ra manages to pull off being his ''own'' herald as a method of showing off, smugly adopting a telltale VoiceOfTheLegion and [[BadassBoast boasting]] of the existence of "the things of your ''worst nightmares''" before dropping his facade and making his BigEntrance.
* HandsOnApproach: Cheetara holds Lion-O's shoulders and tells him to relax while advising him on how to induce Sight Beyond Sight. Lion-O does not relax.
* HeDidntMakeIt: Grune performs the silent headshake variant when telling Claudus of Panthro's loss
* HeWhoFightsMonsters: Lion-O [[DiscussedTrope discusses]] this trope in regards to the Cats' war with the Lizards while explaining his defense of the Lizard prisoners and demanding their release.
* HearingVoices: [[spoiler:General Grune]] hears the evil variety, courtesy of Mumm-Ra.
** Kaynar also apparently hears voices in his head because he's insane. He also likes talking back.
* HeartIsAnAwesomePower: [[spoiler: In ''Native Son'', Tygra's act of forgiveness is the counter to the Ancient's curse borne of pride.]]
* TheHedgeOfThorns: The Briar Woods serves as one to the [=ThunderCats=], who enter to flee their Lizard pursuers, get lost, and search for a way out along with the [[{{Lilliputians}} Lilliputian]] Petalars.
* HereWeGoAgain: In the two-minute short "Snarf: Butterfly Blues" Snarf goes to enormous lengths, risking his own hide to keep baby Lion-O from harm while he chases butterflies. Snarf ''finally'' puts Lion-O to bed, only for him to awaken at the sight of even more butterflies!
* HesitationEqualsDishonesty:
** In "Omens Part 1" Lion-O's "tell" when lying about whether he's seen anything in the Sword of Omens, which Jaga can see right through.
** In "Legacy" it's Leo's "tell" when his superior makes noise about a rebellion, though he doesn't catch it.
* HeyCatch: During Lion-O's RiteOfPassage, Tygra abruptly yells this while tossing Lion-O a practice sword, giving Claudus an opening to charge at Lion-O with Sword of Omens in hand.
* HiddenElfVillage: The Tiger clan has spent generations in a secluded village in the mountains [[spoiler:after their ancestors were shunned by the other Cat clans because they remained loyal to Mumm-Ra during the rebellion. The Tigers' pride and reclusiveness ultimately dooms them.]]
* HiddenPurposeTest: Lion-O's RiteOfPassage is not just a test of his skill at handling the Sword of Omens, or the Eye of Thundera deciding his worth, but specifically whether he's able to see visions within the sword itself.
* HigherTechSpecies: The Lizards, much to Thundera's shock.
* {{Homage}}: The two-minute short "Snarf: Butterfly Blues" pays tribute to WB cartoons like ''WesternAnimation/{{Animaniacs}}'' and the ''WesternAnimation/LooneyTunes,'' and the babysitting episodes of ''WesternAnimation/TomAndJerry.''
* HonorableElephant: The meditative elephant village.
* HopeSpot: [[spoiler:Surely loyal General Grune/General Panthro will help his old friend Claudus fight against the Lizards! Wait, what is that in his hand?]]
** [[spoiler:Surely Pumyra will pick up the Tech Stone and flee with it to safety, or even use it against Mumm-Ra! Wait, she's throwing it to him...and [[{{Squick}} kissing his hand]]?]]
* TheHorde: General Slithe and his Lizard army, in service to Mumm-Ra and Grune
* HorseOfADifferentColor: Thunderian mounts used by the military and royal family are pale-blue-furred MixAndMatchCritters
* HorsebackHeroism: How Lion-O enters during his BigDamnHeroes scene. His father even pauses to ''bow'' to him.
* HostageForMacGuffin: [[ZigZaggedTrope ZigZagged]]. Grune [[InvokedTrope attempts]] to engineer a trade: the Sword of Omens in exchange for a hostage he's holding, but Claudus rejects the offer, and both the Clerics and Lion-O interrupt Grune's retaliation long enough for Claudus to mount a successful rescue. [[spoiler: But the hostage isn't Panthro...and [[DisguisedHostageGambit isn't a hostage]].]]
* HowTheMightyHaveFallen: Slithe gloats, "How quickly things change for the Cats. From top predator to EndangeredSpecies, in a single day!"
* HumanoidAliens[=/=]PettingZooPeople: Damn near everyone and everything [[WorldOfFunnyAnimals on Third Earth]], all given IntelligentGerbil characterization.
* HumiliationConga: In the two-minute short "Snarf: Butterfly Blues" BadlyBatteredBabysitter Snarf has to go through a gauntlet of pain and anguish to keep the infant Lion-O out of trouble.
* HybridMonster[=/=]{{Planimal}}: The Ramlak, a ManEatingPlant with the M.O. of a GiantSquid.
* IAmYourOpponent[=/=]IGotYouCovered: Tygra jumps in when Lion-O puts himself between two stockaded Lizards and an AngryMob that wants to ''make'' him move, informing the crowd "You better be sure you want to do this because ''I've'' got his back." Cheetara soon follows suit.
* IHaveThisFriend: [[InvertedTrope Inverted]], when Jaga gently nudges Lion-O towards admitting that he's seen a vision in the Sword of Omens by announcing that "The Book says that our greatest king will possess the ability of "[[{{Precognition}} Sight Beyond Sight]]," which has the desired effect of prompting Lion-O to ask a TrialBalloonQuestion... "Like having visions?"
* IShallTauntYou: Oh, Lion-O...
** In "Omens Part 1" Tygra goads Lion-O into a telegraphed move during their ChaseFight game with a calculated: "When it comes to everything except the crown, you're [[AlwaysSecondBest always going to be second place]]." He even [[LampshadeHanging lampshades]] the effectiveness of it: "When are you gonna learn, brother?"
** In "The Duelist and the Drifter", the Duelist goads Lion-O into a fight by calling him a coward. It works since he also indirectly mocks Lion-O's father Claudus in the process.
** Later in the same episode, the Drifter gets in some pointed digs at Lion-O's impatience and overexertion, the better to dance circles around him.
* IWillOnlySlowYouDown: [[spoiler:Jaga says this word-for-word before his HeroicSacrifice.]]
* IdenticalGrandson: In "Journey to the Tower of Omens" Captain Tygus and Leo, shown in {{flashback}}, look a lot like Tygra and Lion-O respectively.
* IfJesusThenAliens: [[DiscussedTrope Discussed]] by Mumm-Ra by way of self-introduction: "Have you not considered that if technology is real, then so are the things of your ''worst nightmares''?"
* IgnorantOfTheirOwnIgnorance: Thundera is a prideful kingdom, ill-prepared for what the outside world can offer compared to its MedievalStasis.
* ImDyingPleaseTakeMyMacGuffin: When the [=ThunderCats=] flee TheSiege, a wounded Jaga insists on stopping to conduct a hasty succession ritual where he presents and fits Lion-O with his father's scabbard-gauntlet, speaks an oath and [[PowerGlows powers it up]] by tapping it with his crozier.
* ImperialStormtrooperMarksmanshipAcademy: The Lizards are pretty bad shots when it comes to dealing with Lion-O and the surviving [=ThunderCats=]. The Cats themselves almost equally so, the arrows fired against the Lizards hit a grand total of two targets on-screen.
** Possibly justified for the Lizards: [[spoiler: it's implied that all the hi-tech weaponry they use in the Seige had been locked up with Mumm-Ra for centuries, and they've only just been outfitted with it since Grune opened the sarcophagus. Therefore they've not had a lot of time to practice with it.]]
* [[spoiler:ImportedAlienPhlebotinum: The Eye of Thundera, alias The Warstone. A PowerCrystal taken as {{plunder}} from a red planet by Captain Tygus for his commander, Mumm-Ra.]]
* ImpossibleTask: A sullen and paranoid Grune [[DiscussedTrope discusses]] his and Panthro's thus-far futile search for the Book of Omens this way, rapidly escalating into declaring it a SnipeHunt and a UriahGambit engineered by Claudus purely to get ''[[ItsAllAboutMe him]]'' out of the Kingdom. Panthro can only snap incredulously at him, and wonder why Grune is ranting about Claudus fearing his [[AmbitionIsEvil ambition]].
* InASingleBound: Lion-O and Tygra jump to absurd heights in their ChaseFight game.
* InTheBack:
** In "Omens Part 2" Claudus is stabbed [[spoiler:by Mumm-Ra disguised as Panthro]] and mortally wounded, with just enough time to inform Lion-O he's SoProudOfYou before dying.
** In "The Duelist and the Drifter", this is attempted and failed [[spoiler:by the Duelist after Lion-O wins their second duel, but the Drifter stops him ''with a willow reed''.]]
* InTheHood: The Clerics helms feature full hood and veil
* InWorkingOrder: Tygra's RayGun and Lion-O's BlackMarket find [[spoiler:the StickyBomb]] are highly intuitive, fully functioning and easy to use.
* IncomingHam[=/=]PreAsskickingOneLiner: You are ''but insects'' to the power of ''MUMM-RA,'' '''THE EVER-LIIIVIIING!'''
* InexplicablyTailless: In-story, there has thus far been no explanation as to why lowerclass Cats like the Thunderkittens have tails, while the upperclass do not. However, it's AllThereInTheManual that tails are the distinguishing [[http://crewofomens.tumblr.com/post/8435103220/i-first-saw-thundercats-on-toonami-when-i-was-young marker]] of Thundera's FantasticCasteSystem. In particular, Panthro has an obvious tail in flashbacks but none in the present.
* InstrumentalThemeTune: Lyricless, though an EtherealChoir underscores it.
* InsultBackfire:
-->'''Lion-O''' (in SarcasmMode): You're just so perfect, aren't you, Tygra?
-->'''Tygra''': Why, thank you, Lion-O!
* IntelligentGerbil:
** The Cats are expansionist predators who've placed themselves at the top of the Animal hierarchy.
** Thundera's games are also a giant VisualPun. The Cats race up a tree, while fighting to ring a bell and lose when they hit water.
* InternalHomage
** Lion-O's invocation of "[=ThunderCats=]! Ho!" is a shot-for-shot remake of the StockFootage used in the original series.
*** At one point, during the Siege of Thundera, King Claudius performs the invocation... which is a double homage, because Claudius is voiced by the ''original'' Lion-O.
** In a brief flashback in "Between Brothers", we see a younger Panthro, without the muttonchops and scars; he looks just like his classic incarnation.
** During the first fight with Mumm-ra's monster in "Recipe for Disaster," Lion-O performs a backflip and fires a beam of energy from the Sword of Omens... referencing the same way he did it in the original series intro.
* InternalReveal: When they're LockedInTheDungeon, Lion-O admits to Tygra that he saw a vision of Mumm-Ra in the Sword of Omens just the day before. Tygra does not take this well.
* InterspeciesRomance: [[spoiler: Mumm-Ra refers to Pumyra as his beloved and he strokes her cheek delicately while saying it. [[{{Squick}} Ew.]]]]
* IronicEcho: The defeat of your enemy is worth ''any'' sacrifice.
** "You like her, don't you?" Both times spoken to Lion-O about two ''very'' different women. The first time he denies it, but the second...
* {{Irony}}: Between Lion-O and Tygra, each brother wants what the other has. Tygra wants the throne and can never have it, Lion-O really doesn't want to be king all that badly but was chosen for it, all he wants is to beat his brother at ''something'' and never can.
** In "Recipe for Disaster" Cheetara comments that Pumyra "isn't exactly the friendliest cat" only for it to be immediately followed by a scene of her tenderly helping a baby creature back to its nest. [[spoiler:Though how much truth this shows about her inner nature may be debatable, [[TheMole all things]] [[EvilAllAlong considered.]]]]
* ItHasBeenAnHonor: In "Song of the Petalars" The group reacts this way when surrounded by Lizards, assuming this is their LastStand. [[spoiler: [[BigDamnHeroes But then Panthro shows up...]]]]
* ItsAllAboutMe: [[spoiler: Pumyra being EvilAllAlong never forgave Lion-O for the fall of Thundera because she died during the battle and was [[BackFromTheDead resurrected]] by Mumm-Ra to [[SixthRangerTraitor infiltrate]] and [[TheMole spy]] on the [=ThunderCats=]. She is even happy to let her race and all others become slaves in a [[CrapsackWorld crapsack universe]] just so she can have her petty revenge against the king who inadvertently let her die.]]
* ItsAlwaysSunnyAtFunerals: It's a beautiful day in the smoldering ruins of Thundera during Claudus's VikingFuneral.
* ItsTheJourneyThatCounts: Emrick tells Lion-O that the good we do and the friends we make are what matter most.
