[[WesternAnimation In Cartoonland,]] [[EstablishingCharacterMoment first impressions are everything.]]
* ''WesternAnimation/{{Archer}}'':
** Archer himself gets his moment near the end of the pilot episode "Mole Hunt" when he [[spoiler:gets an erection at the thought of his mother dying]]. May also double as an EstablishingSeriesMoment.
** Cheryl gets hers in Episode 5, when she goes on a long tangent about her disturbing love for fatal erotic asphyxiation. Up until this point, she was shown as being only moderately weird and occasionally baby crazy. this cranked it up to eleven.
** Krieger's is undoubtedly when he introduces [[https://www.youtube.com/watch?v=UDekhoeEoCc Fister Roboto]], his sex robot. Note that these are his first lines in the entire series.
* ''WesternAnimation/{{Arthur}}'': The first episode to focus on Francine (and the second overall) sees her trying to refrain from playing kickball long enough to look especially nice for her school picture, but Francine is unable to help herself. By the time the picture is taken, she looks scruffy and grungy, while wearing a dress and a relaxed hairstyle.
* WesternAnimation/BugsBunny gets his in "WesternAnimation/AWildHare", when he appears out of the ground and establishes his collected, casual attitude with "Eh, what's up, Doc?"
* ''WesternAnimation/TheBackyardigans'': Uniqua establishes her character - and really the entire series - by immediately making it clear that girls are just as capable of being great pirates as boys are, and getting Austin, Pablo, and Tyrone to follow her lead.
* ''WesternAnimation/{{Ben 10}}'':
** The titular Ben Tennyson gets this in the very first episode: Before the opening theme song, he's shown bored out of his mind, making a paper airplane that he then throws at his teacher, copping a delighted look on his face. After the theme, he is seen rushing to the aid of a terrified kid who's being picked on by two bullies. Though he fails, he refuses to budge. That shows that, while he still has immature tendencies, being ten years old and all, he is willing to stand up to any evildoer, knowing full well that there is a high percentage that he can lose the fight.
** In ''{{WesternAnimation/Ben 10 Omniverse}}'', Rook's first scene in a fight has him show what his Prototool can do, taking out three alien criminals singlehandedly... and in conversation with Ben, show he's SarcasmBlind and LiteralMinded.
* In ''WesternAnimation/SouthPark'', both of Kyle's parents have these. The first thing Sheila Broflovski does in the show? Try to cancel ''Terrance and Phillip'' by going on strike with all of the other parents. 4 episodes later, Gerald is being too hard on Kyle this Hanukkah for having what was thought to be an imaginary friend. They both mellow out a little as the series progresses, for the most part.
* WesternAnimation/WoodyWoodpecker established his heckler nature by bursting onto the screen, saying a smug "Guess Who", dodging a subsequent blow from Poppa Panda, retorts by honking his nose like a horn, and then unleashes his legendary laughter as he treks off to reek havoc on the Panda's rooftop. His second (albeit first solo) appearance in "The Cracked Nut", where he sings a BraggingThemeTune about how he's crazy and he's proud of it, is another one of these moments.
* WesternAnimation/DaffyDuck's "I'm just a crazy ol' darnfool duck" line from his debut in WesternAnimation/PorkysDuckHunt".
* ''WesternAnimation/AvatarTheLastAirbender'':
** Aang's is where after being restored from a HumanPopsicle, his first words were to ask Katara if she wanted to go penguin-sledding. He also gets an EstablishingCharacterMoment for the Avatar in the second episode, by going into the [[SuperMode Avatar State]] and [[CurbStompBattle quite effortlessly wiping out everyone on the ship]] in under a minute.
** The first two episodes quickly show Zuko's obsession with capturing the Avatar in order to return from his exile. He also gets a more subtle one when he gets Aang to surrender to him in exchange for him sparing the Southern Water Tribe - most villains would [[ILied level the place anyway]] [[ForTheEvulz for their own amusement]], but [[NobleDemon Zuko proves to be as good as his word]].
** Iroh as well. He just wants to finish his game and drink some tea.
** Ozai's first talking-and-doing-things appearance (as opposed to the brief silhouette he got a few episodes earlier) features him burning Zuko's face. His own son. In public. As the 13 year old boy begs for mercy. [[AbusiveParents That's all we need to know about the guy.]]
** Azula's first appearance during Zuko's flashback in "The Storm". All you can guess about her is that she's family by the fact that she's standing next to Iroh, has yellow eyes, and is dressed in very similar robes, but when she's seen ''smiling'' as Zuko gets disfigured, you ''know'' she's going to be trouble whenever she'll show up. When she shows up as a named character it is one of these. We can tell from her first appearance that, as opposed to her sympathetic AntiVillain brother, she is a vicious creature, and that is the truth all the way through the series.
--->'''Azula:''' Do the tides command this ship?\\
'''Captain:''' Uh, I'm afraid I don't understand.\\
'''Azula:''' You said the tides would not allow us to bring this ship in. Do the tides command this ship?\\
'''Captain:''' No, Princess.\\
'''Azula:''' And if I were to have you thrown overboard, would the tides think twice about smashing you against the rocky shore?\\
'''Captain:''' No, Princess.\\
'''Azula:''' Well then, maybe you should worry less about the tides, who have already made up their minds about killing you, and worry more about me, who's still mulling it over.
*** Azula gets another in the same episode. She practices [[ShockAndAwe lightningbending]], and gets the extremely difficult firebending move right on the first try, but one lock of hair is out of place. She gets angry and says "Almost perfect isn't good enough!" [[spoiler: This foreshadows her later VillainousBreakdown, which happens when she is again not quite perfect, and in this case [[MachiavelliWasWrong on something bigger than just a hair]].]]
** Mai is established as a DeadpanSnarker EmotionlessGirl and formidable {{Ninja}} and KnifeNut in less than a minute.
** Toph's entrance, which consists of her effortlessly beating a man about five times her size in the Earth Rumble ring without breaking a sweat also qualifies her as a LittleMissBadass. Did we mention that she's also [[DisabilitySuperpower blind]]?
--->'''[[LargeHam The Boulder]]''': [[ThirdPersonPerson The Boulder]] feels conflicted about fighting a young blind girl.\\
'''Toph''': [[LittleMissSnarker Sounds to me like you're scared, Boulder!]]\\
'''The Boulder''': ...The Boulder is over his conflicted feelings and now he's ready to bury you in a rockalanche!\\
'''Toph''': [[TrashTalk Whenever you're ready, the Pebble!]] ''[laughs]''
* ''WesternAnimation/TheLegendOfKorra''
** The titular character is introduced as a four-year-old, breaking through a wall while bending three elements at once and screaming [[BadAssAdorable "I'm the Avatar, YOU GOTTA DEAL WITH IT!"]]
** When Tenzin's entire family is introduce we get a good description of each of their personalities Ikki was introduced as asking "AreWeThereYet" ad nauseum, while her little brother Meelo chews his father's head.
** [[TheCharmer Bo]][[BigFun lin]] introduces himself this way via a [[FunnyBackgroundEvent Funny Background Event]] where he spots Korra and decides, after some [[CasanovaWannabe preening]], to [[TheDulcineaEffect help her out of an argument]] with his earthbending teacher.
** [[IronLady Chief Lin Bei Fong]]. She's introduced by grilling [[spoiler:Korra]] in the interrogation room. [[SympatheticInspectorAntagonist She's dead serious, pissed off, and 100% focused on her job.]] Even though the one in custody is none other than [[spoiler:The Avatar]]. We've got a hardass over here, folks.
** Asami crashes into Mako on the street. A couple minutes later, she takes him out to dinner, and gets her father to fund his team to make up for it.
** In the Season 1 finale, we are introduced to Tenzin's older brother [[CrazyAwesome Bumi]]. His only action in the ten seconds of screen time he has is to let out a huge WAHOOO! before grinning like a maniac.
** In Season 2, Mako's first appearance is him, now a cop, stopping out a van full of criminals by knocking them over. [[BondOneLiner Then he suggests that they should call the police for help]]. Given his dour disposition throughout the first season, this marks a big change. [[spoiler:He later shows Korra he actually wrote potential one-liners ahead of time.]]
** Zaheer's introduction shows him locked away in an isolated mountain prison. He spends a minute politely educating his guards about some obscure Airbending philosophy, hinting that he's AffablyEvil and something of a WarriorPoet, before he breaks out using Airbending (which he's able to use like a master [[InstantExpert despite only having the ability for at few days, at most]]) and declares his intention to destroy the White Lotus and the Avatar, hinting at him being a [[BombThrowingAnarchists Bomb Throwing Anarchist]].
** Kuvira, the main antagonist of the 4th season is firmly established in her first scene by single handily taking down a group of bandits and giving them two choices; Join her new empire and live or remain attached to the rail tracks and die.
* ''WesternAnimation/BatmanBeyond'':
** Terry [=McGinnis=]' first scene in had him defending monorail passengers from a Jokerz gang member harassing them. Later scenes showed him with a bad attitude and temper, but [[JerkWithAHeartOfGold established his character arc]] for the first few episodes.
** Mad Stan in is introduced shouting "BLOW IT ALL UP!" into the camera and sticking a bomb onto a support pillar while heavy metal music plays in the background. Guessing he's a {{Bomb Throwing Anarchist|s}} isn't exactly difficult.
* ''WesternAnimation/TheBoondocks'':
** Huey Freeman begins the series by claiming that while he's not a prophet he has had a prophetic dream where he brought a [[WhiteAngloSaxonProtestant whitebread garden party]] to riot with the announcement that "UsefulNotes/{{Jesus}} was black, UsefulNotes/RonaldReagan was the Devil, and the government is lying about 9/11". Later in the episode, he attends an actual garden party, and the WASPs there are completely unphased by his Left-Wing rhetoric. This shows that while he is very WiseBeyondHisYears, he's still one kid shouting at a hurricane.
** Huey's Granddad, Robert Freeman gets his debut by smacking Huey across the head immediately after his aforementioned dream and telling him "You'd better learn to lie like your Graddaddy", showing that he has no patience for the boy's activism. There's also a hint at his DirtyOldMan tendencies in his next scene, where he's jazzercising to a Billy Blake infomercial... [[NakedPeopleAreFunny completely naked.]]
** Ed Wuncler III makes his first appearance brazenly talking about how he got washed out of service in UsefulNotes/{{Iraq}} for [[BringMyBrownPants constantly shitting himself]] and that he doesn't care, because he's rich. Despite this, he proves to be enough of a FearlessFool later in the episode when he demonstrates his BulletproofVest by ''demanding'' Riley to fire a shotgun on him. As his grandfather puts it, "In twenty years, that boy will be president of the United States... and he'll still be a fucking idiot."
** Said grandfather, Ed Wuncler, is mostly benign in his first appearance. He fully shows [[CorruptCorporateExecutive what kind of man he is]] in his second appearance, where he arranges a HostileTakeover of Jasmine's LemonadeStand, [[MoralEventHorizon tricking her into voluntarily working in defiance of child labor laws, only to make a killing off of "cruelty-free lemonade" when protests start,]] [[WouldHurtAChild leaving poor Jasmine in debt for all her efforts]]. [[{{Greed}} Bear in mind that he's already]] [[{{Fiction 500}} the richest man in the state.]]
** Gin Rummy is a {{White Gang Banger|s}} [[NoCelebritiesWereHarmed mockery]] of DonaldRumsfeld played by Creator/SamuelLJackson. It's not surprising that his first appearance has him saying that "the absence of evidence is not the evidence of absence", a quote said by Rumsfeld in response to no-one finding [=WMDs=] in Iraq. When Riley doesn't get what he's saying, he responds with [[ActorAllusion the "Say what again" speech taken from Jackson's character in]] ''Film/PulpFiction''.
* ''WesternAnimation/InvaderZim''
** Zim's first appearance has the [[TheNapoleon vertically-challenged megalomaniac]] recalling how he single-handedly thwarted his species' previous attempts at universal conquest by directing his HumongousMecha on a planet-wide rampage ''[[MikeNelsonDestroyerOfWorlds while he was still on his own planet]]''. Though what really establishes his personality is that he brings this up ''proudly'' and doesn't seem to understand why his bosses aren't pleased with him about it.
--->'''Zim:''' I put the fires out.\\
'''Tallest Red:''' You made them ''worse!''\\
'''Zim:''' Worse... ''or better?''
** From the same episode, Gaz's first line establishes both her antisocial personality and her interesting priorities:
--->'''Gaz:''' ''[looking inside the refrigerator]'' Dib drank the last soda. ''He. Will. Pay.''
** Then there's GIR...
--->'''GIR:''' GIR, reporting for duty.\\
'''Zim:''' GIR? What does the "G" stand for?\\
'''GIR:''' [[{{Cloudcuckoolander}} I don't know]]... ''[suddenly begins giggling and hitting himself on the head]''
* ''WesternAnimation/KimPossible''
** Used with Shego in the pilot, where she instantly shows off how savvy she is.
** Averted with Drakken in the very same episode, when he disabled an outside camera by rope gliding. [[EarlyInstallmentWeirdness He never did such feats ever again.]]
** Ron Stoppable's first moments establish him as the Goofy Best Friend:
--->'''Kim''': A naked mole rat? Ron, ever think about getting a normal pet?\\
'''Ron''': Like what?\\
'''Kim''': Something not naked. (Rufus [[BlowingARaspberry blows a raspberry]] at Kim)\\
'''Ron''': (dramatically) Never be normal, that's the Ron Stoppable motto!
* WesternAnimation/DarkwingDuck's very first scene in his premiere episode perfectly illustrates that "ego the size of a small planet" Taurus Bulba will later summarize. It leaves no doubt what this protagonist's personality is like.
* ''WesternAnimation/RubyGloom'''s [[OneWePreparedEarlier first episode]] gives introductory scenes to most of the cast. The best one may be Misery's, where a few sentences into an already gloomy conversation, she puts the always-optimistic Ruby at a temporary loss for words by describing her own genetic predisposition toward being struck by lightning.
** Two seconds later, Ruby further establishes her own character by changing the subject and managing to lift her spirits a little anyway.
* General Grievous' first appearance in ''Franchise/StarWars'' canon is the season one finale of ''WesternAnimation/StarWarsCloneWars'', where he takes on a team of six Jedi, and kills or incapacitates all but one of them.
** Unfortunately, while Grievous' reputation as a dangerous foe carried over into ''Film/RevengeOfTheSith'', all of his screen time is spent running away or getting his butt handed to him by Obi-Wan. So in the ExpandedUniverse, Grievous is quickly established as a legitimate threat, but in the movie it just comes across as an InformedAbility.
** In the movie, he first appears as a skull-faced boss villain, and the first thing he does is coughing uncontrollably. Thus: He is sick (In fact he suffers from IncurableCoughOfDeath), and he cannot be a robot because he is sick (CyberneticsEatYourSoul, someone?), so there must be something organic somewhere to [[DragonTheirFeet Dragon His Fett]]. An Establishing Character Moment saying he's a pitiful, or by now at least pitiable, villain.
** The shift in characterization is a result of the constantly shifting production of Episode III. While initially he was supposed to be a powerful and feared Jedi hunter, Lucas decided to rewrite the character as a moustache-twirling coward. The ''in-story'' reason is that towards the end of the Clone Wars cartoon, Mace [[Creator/SamuelLJackson Windu]] Force-Crushes his chest -- and with it, his few remaining organs, leaving Grievous horribly weakened during the events of Episode III. As for Grievous vs. Kenobi? Obi-Wan is considered the master (not ''a'' master, ''the'' master) of the ultimate defensive lightsaber form, and thus could block all Grievous' attacks 'cause he's so damn good at blocking attacks. And when Grievous kept failing to hit him, he got angry, which made him get sloppy, which made him get angrier, which made him get sloppier, and... you get it.
*** Very true. A deleted scene gives him a very different ECM... with him executing Shaak Ti. Being a deleted scene this was retconned [[spoiler: and her death was saved for a much later CrowningMomentOfAwesome for Vader's Apprentice.]]
* ''WesternAnimation/FamilyGuy'''s Glenn Quagmire and his dealings with a woman he picked up earlier that night:
-->'''Woman''': Hey, Glenn, I have a question for you: what do you do for a living?\\
'''Quagmire''': ''[wearing a lecherous grin]'' And I have a question for you: ''why are you still here?''
* ''WesternAnimation/GravityFalls'':
** Creator Alex Hirsch pinpoints the gift shop scene towards the end of the episode as being this. [[AdorablyPrecociousChild Dipper]] chooses the pine tree hat due to practicality, since he lost his old one during the events of the episode. Meanwhile, [[GenkiGirl Mabel]] chooses a grappling hook, revealing how unpredictable the character can be.
*** Could also be considered a moment for Stan. After making fun of the twins as they return, Stan notices that they look down and offers them each a free item from the gift shop under the flimsy guise of ordering too much stock, showing that despite how callous he may come off he cares for his niece and nephew deep down.
** Bill Cipher's first appearance quickly establishes him as entertainingly crazy and ''utterly terrifying'', as his first act (after poking fun at Gideon) is to casually extract the teeth of a nearby deer and offer them to Gideon--and when Gideon rejects them, Bill just as casually puts them right back.
-->'''Gideon:''' "''YoureInsane''"\\
'''Bill:''' "Sure I am! [[InsultBackfire What's your point?]]"
** Admit it, the first time you see Pacifica Northwest, you will think she's the AlphaBitch. [[spoiler: Well, that's in season 1 before her CharacterDevelopment in season 2.]]
*** Also for her father [[AbusiveParents Preston Northwest]]. What's his advice for Pacifica? "Don't lose".
* ''MickeyMouse'': Mickey's appearance in ''WesternAnimation/SteamboatWillie'' shows him whistling and smiling as he steers the boat before being told off by the actual boat captain, Pete. This sets in place his personality as a happy go-lucky yet mischievous mouse.
* The first episode of ''WesternAnimation/TotalDrama'' was full of this. Some memorable ones were Owen's excitement, Cody's CasanovaWannabe entrance, Leshawna starting a fight with Harold, and Tyler and Bridgette's klutzy behavior. Courtney's adherence to rules and order, strategic AlphaBitch status were also partly revealed in the second episode.
* After being played up as TheAce by Eddy throughout ''WesternAnimation/EdEddNEddy'''s run, Eddy's brother's first act in TheMovie is [[ComedicSociopathy to beat up Eddy and Edd]]. So instead of the great guy Eddy's portrayed him as, Eddy's brother is a monster who tortures children for fun. [[FridgeHorror And he works at an amusement park]]. [[spoiler: [[CrowningMomentOfAwesome He's defeated by Ed.]]]]
* The Franchise/{{Transformers}} franchise has plenty of these:
** Due to ''[[Franchise/TransformersGeneration1 G1's]]'' LoadsAndLoadsOfCharacters, these usually take the form of an IntroDump, but Starscream's is particularly notable -- the ''first thing he says'' is how the Autobots would have lost a long time ago if he was in charge, establishing him as, well, TheStarscream.
** Dinobot enters ''WesternAnimation/BeastWars'' by [[DefectorFromDecadence defecting from the Predacons]] and challenging the Maximals' leader, Optimus Primal, to a duel to the death for leadership. Up to now, he's been portrayed as a back-stabbing villain, fully subscribing to his race's [[TheStarscream tradition of treachery and dishonor]]. Then, when Optimus Primal slips and nearly falls off the narrow bridge they're fighting on, Dinobot helps him up, revealing himself to be a decent, honorable guy, for all that it's worth. This quote illustrates it:
--->'''Optimus Primal:''' What're you doing? You'd won!\\
'''Dinobot:''' You slipped. To defeat you in such a manner would be [[HonorBeforeReason lacking in honor]]. ''I'' would not have earned the right to lead. I prefer to defeat my opponents the old fashioned way -- ''BRUTALLY''!
** Blitzwing from ''WesternAnimation/TransformersAnimated'' gets a particularly epic one in his first scene, firmly placing him as a [[EnsembleDarkhorse fan favorite]] for the new series:
** The Decepticons from ''WesternAnimation/TransformersAnimated''. We see Starscream being [[TheStarscream starscreamy]], Lugnut [[UndyingLoyalty calling him a traitor]] and [[SycophanticServant praising his GLORIOUS master]], Megs himself being the imposing and powerful leader he is, and a conversation between Blitzwing and Blackarachnia.
--->'''[[AnIcePerson Icy Blitzwing]]''': As usual Blackarachnia: your demeanor is as unpleasant as zat accursed organic mode of yours.\\
'''[[DarkActionGirl Blackarachnia]]''': Blow it out your [[UnusualEuphemism actuator]], three-face.\\
'''[[TheAhnold Hothead Blitzwing]]''': Ze name is Blitzwing, insect! Remember it! Cause it's the last thing you will hear before I-\\
'''[[{{Cloudcuckoolander}} Random Blitzwing]]''': -express my feelings in song! ''Ze itsy bitsy spider...''
** From the same series, the Starscream clones. And then, in case you missed it, Slipstream outright states their major personality traits:
---> [[OppositeSexClone Slipstream]], pointing to each of the others in turn: He's a [[LovableCoward coward]], he's an [[ItsAllAboutMe egomaniac]], he's a [[ProfessionalButtKisser suckup]], and he's a [[BlatantLies liar]].\\
Starscream: So which part of me did you come from?\\
Slipstream: ''[[YouDoNotWantToKnow Don't ask.]]''
** Showing that ''Transformers'' loves this trope, ''[[WesternAnimation/TransformersPrime Prime]]'' has Knock Out and Breakdown, AKA ThoseTwoBadGuys, showcasing the former's vanity and the latter's bruiser status, and then they [[BashBrothers manage to work in tandem]] to overpower ''Optimus'' and the rest of the Autobots, showing that they aren't normal Vehicon {{mooks}}.
*** The first thing Cliffjumper does in ''Prime'' is boast about freaking out some cops. The second thing he does is jump into a fight alone with several Vehicons. [[spoiler:The third thing he does is die.]]
* The iconic TitleSequence on ''WesternAnimation/TheSimpsons'' shows the viewer all they need to know about the eponymous family:\\
Bart is WritingLines in detention for some NoodleIncident, and eagerly runs off and skateboards out of there once the bell rings, showcasing his hellion tendencies.\\
Homer starts out carefully handling a radioactive rod... only to carelessly toss it away and bolt out the door, not noticing the rod bouncing onto his shirt, demonsrating his boorish recklessness.\\
Lisa gets in trouble at music class for breaking away from her classmates' staid, half-hearted session with a soulful freestyle, displaying her will to express herself in defiance of society's norms.\\
Marge is reading a mothering magazine at the grocery checkout, not noticing that Maggie has crawled onto the conveyor belt, displaying how her desire to be a wholesome suburban matriarch leads her to miss the eccentricities of her family.
** In the first full-length episode ever broadcast, "[[Recap/TheSimpsonsS1E1SimpsonsRoastingOnAnOpenFire Simpsons Roasting on an Open Fire]]", Lisa's intelligence and precociousness are demonstrated by her eloquently telling off her Aunt Patty for badmouthing Homer.
-->'''Lisa:''' What, Aunt Patty?\\
'''Patty:''' Oh, nothing, dear. I'm just trashing your father.\\
'''Lisa:''' Well, I wish you wouldn't because, aside from the fact that he has the same frailties as all human beings, he's the only father I have. Therefore, he is my model of manhood, and my estimation of him will govern the prospects of my adult relationships. So I hope you bear in mind that any knock at him is a knock at me, and I am far too young to defend myself against such onslaughts.\\
'''Patty:''' Mm hm. Go watch your cartoon show, dear.
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic''
** When we first meet Twilight in "[[Recap/MyLittlePonyFriendshipIsMagicS1E1MareInTheMoon Friendship is Magic Pt 1]]", she's studying with her friend/assistant Spike, who's trying to get her to relax, and is shown to be uninterested in making friends and a bit insensitive at times. After being sent to Ponyville, she meets the rest of the main cast through a series of these. Pinkie Pie jumps in the air while gasping dramatically and promptly runs away, with no explanation given for [[{{Cloudcuckoolander}} her bizarre actions]]. Applejack greets Twilight over-enthusiastically before inviting her to brunch with [[TheClan her large family]]. Rainbow Dash crashes into Twilight and sends her into a mud puddle, tries (and fails) to clean her up with a speed-based stunt, openly laughs at Twilight's resulting messed up hair, proudly declares her ambition to join an elite aerial team, and clears the sky in [[MemeticMutation ten seconds flat]]. Rarity is decorating for the Summer Sun festival, gives Twilight a makeover, and starts gushing over the glamour of Canterlot on learning that's where Twilight is from. Fluttershy is working with small animals and is painfully shy, but opens up a bit when [[CutenessProximity she gets a chance to talk to Spike]]. And Pinkie Pie wasn't scared of Twilight; she just realized that Twilight was new in town and didn't know anyone (yes, ''the second they met''), and left to throw her a welcoming party.
*** In something like a DeconReconSwitch, Twilight's new friends get a second set of establishing moments after things get serious and they embark on TheQuest. The first ones made her annoyed at them, the second ones teach her to appreciate them. (They also hint at their destiny as the carriers of the Elements of Harmony.) Applejack displays she's [[TheReliableOne honest and reliable]]. Fluttershy's sensitivity calms down a hostile monster the others could only think to fight. Pinkie Pie shows the usefulness of her happy attitude in overcoming fear. Rarity helps them get ahead by making a generous personal sacrifice. And Rainbow Dash shows that, in spite of her insensitive demeanor, she's always loyal to her friends in the end.
** Happens with the introduction of Trixie in [[Recap/MyLittlePonyFriendshipIsMagicS1E6BoastBusters "Boast Busters]] "[[IncomingHam Come one, come all!]] [[AttentionWhore Come and witness]] the [[SmallNameBigEgo AMAZING magic]] of the [[TrrrillingRrrs Grrreat]] and [[AnythingYouCanDoICanDoBetter Powerful]] ''[[ThirdPersonPerson Trrrixie]]!''"
** [[AlphaBitch Diamond Tiara]] qualifies in the ColdOpen to "[[Recap/MyLittlePonyFriendshipIsMagicS1E12CallOfTheCutie Call of the Cutie]]". When we first see her, she [[BrattyHalfPint forcefully]] passes a note to Apple Bloom who gets caught. When Cheerilee, the teacher, asks for Apple Bloom to read the note, she mentions it's blank. Diamond Tiara says, "[[KickTheDog Remind you of anypony?]]", referring to [[FantasticSlur Apple Bloom's blank flank]] before [[KidsAreCruel leading the class into]] [[GigglingVillain laughing at her]].
** In "[[Recap/MyLittlePonyFriendshipIsMagicS2E4LunaEclipsed Luna Eclipsed]]", we finally get to see how Princess Luna normally acts. The answer? '''[[IncomingHam VERY LOUD]]'''! Immediately followed by [[NoSocialSkills complete confusion]] at everypony's terrified reactions, and her storming off with a huffy "Very well, then! Be that way!"
** In "[[Recap/MyLittlePonyFriendshipIsMagicS2E1TheReturnOfHarmonyPart1 Return of Harmony Part 1]]", Discord first appears in the stained glass windows, demonstrating a sense of mystery and [[ActuallyPrettyFunny even humour]] through his antics amongst the window displays, as well as great knowledge of the Mane Six that [[TheOmnipotent by all rights he shouldn't have]], what with being [[TakenForGranite sealed in stone]] for over a millennium now.
--->'''Discord:''' Make sense? Oh, what fun is there in making sense?
** Another component of the scene that helps in establishing Discord is the reaction Princess Celestia (the only one present that actually knows him) has towards him. [[OoCIsSeriousBusiness In contrast to the calm, easygoing, and playful personality she displayed throughout the entire previous season]], she takes him dead seriously [[BewareTheSillyOnes despite his somewhat goofy self-presentation]] and tries her best to stop his {{Breaking Lecture}}s from getting started, [[KnightOfCerebus demonstrating how serious a threat he is]].
* ''WesternAnimation/TheAvengersEarthsMightiestHeroes'':
** Comicbook/BlackWidow briefly appears in the episode "Breakout", the first to air on Creator/DisneyXD. Her appearance can be summed up as "[[MaleGaze buttshot]], [[MyEyesAreUpHere full-length bodyshot]], [[MaleGaze walking away buttshot]], exit".
** Similarly, Comicbook/IronMan first appears in "Breakout" (following some scenes in promotional shorts and a compilation of those shorts) as he effortlessly breaks up a weapons sale, tells off Doctor Doom's representative, blows off ComicBook/NickFury and SHIELD, and dismisses a request that soon comes back to massively bite him (and everyone else) in the ass. If you ''do'' count the shorts and their compilations, Iron Man's establishing moments come when he fights a giant robot and shrugs off advice that he'd be better off making weapons than fighting evil directly and alone.
** ComicBook/TheWasp's establishing moment comes in the short "Enter the Whirlwind" (also featured in the show's fifth chronological episode). She tells ComicBook/AntMan that the two of them need to find a better use of their time than private scientific research, then goes outside to fight Whirlwind. Ant-Man eventually comes to help Wasp, so she tells him they could use their powers to benefit others through crime-fighting.
** With Black Widow at his side, ComicBook/{{Hawkeye}} makes his debut in "Hulk vs. The World" by striking the [[Comicbook/IncredibleHulk Hulk]] with two arrows, descending from a plane on a zip line, and quipping, "Tick tick boom!" right before the arrows explode.
*** While she initially appears in a cameo appearance in this short, ComicBook/{{Mockingbird}}'s actual introduction has her crack an affectionate joke at Hawkeye's situation, snark at his confusion over her new duds and status as a special agent, then offer to help while subtly flirting with him. Pretty much sums up her personality. Later we have, when captured, actually striking up a conversation with several male guards, [[OneOfTheBoys seemingly befriend them]], and nearly trick them into loosening her cuffs.
** The Grim Reaper is introduced shooting one of his own men in the back as part of a Trojan Horse plan, get picked up in security for his prosthetic arm while they also detect the Satan's Claw glove in his belongings, before effortlessly wasting each of the SHIELD agents who attempt to stop him, [[CreepyAwesome all the while snickering like a psychopath]]. Following this has ComicBook/NickFury chase after him and Baron Strucker, who he was breaking out, fight them both, lose a good few years of his life thanks to the youth-draining effects of Satan's Claw without batting an eye, then taking the two down and basically dragging them back to their cells, all without breaking any notable sweat.
* ''WesternAnimation/TeenageMutantNinjaTurtles2003''
** Looking back at the first episode, it's hilarious how straightforward this was. As the first scene was a practice session, we were treated to, in order, Donatello and Michelangelo being berated for their failed attempts to [[ItMakesSenseInContext put out a candle]] with some amount of fondness from Splinter, "Poor choice, Raphael", and Leonardo succeeding where his brothers failed. That sums up the series, with, perhaps, more jokes and TechnoBabble from Mike and Don, respectively.
** There's also the first verbal exchange between Raphael and Leonardo, right after the training session:
---> '''Raph''': Teacher's pet!\\
'''Leo''': Ninja dropout!\\
'''Mikey & Don''': [[DoNotTauntCthulhu Oooooooh!]]
* Although a well-established character in other media and previous shows, even if you didn't know anything about the character, the opening theme for ''WesternAnimation/BatmanTheAnimatedSeries'' told you all you needed to know about Batman in under a minute. Quoting from [[http://www.comicsalliance.com/2011/11/04/ask-chris-78-why-the-batman-the-animated-series-opening-is/#ixzz236yqEitR Chris Sims review of the series opening]];
--> ''"We know that this guy is a crime-fighter who probably doesn't have any super-powers. At the very least, he can't run faster than a car and if you punch him, he'll feel it. We know that he doesn't use guns, and instead relies on being an incredible fighter who uses other means to deal with his enemies. We know that he's violent, and that he hates crooks, but he doesn't kill them and instead hands them over to the justice system. We know he exists because there's unchecked crime in this city that the police just cannot fight by themselves, even if through extraordinary means. Also, he drives a dope car."''
* In ''WesternAnimation/DrawnTogether'', a few happen in the first episode.
** Clara, upon meeting Foxxy for the first time, assumes she's a servant and asks her to fetch her bags, which Foxxy does not take well.
** Captain Hero's desire for AnythingThatMoves is indicated when he confesses that he'd "stick and stir any one of those broads," but wants a "hot black chick," too. When that is granted, he waits, in vain, for a twelve year old and a donkey to come.
** Toot gets two. Her first is dancing in an attempt to impress Xandir and causing the entire house to shake. Her second, after deciding to become "the bitch" is [[KickTheDog to lie to Xandir's kidnapped girlfriend and claim that he's cheating on her]].
* ''WesternAnimation/JackieChanAdventures'' establishes the three main characters pretty well in the first episode. Jackie in his first scene is shown [[AdventurerArchaeologist dodging flying arrows in a Bavarian castle]] as well as using {{improvised weapon}}s to do so. Uncle first appears like a sweet, caring old man before going straight to his trademark DopeSlap and his CatchPhrase "... [[AndAnotherThing and one more thing!]]" Jade is shown breaking into the underground military base of one of the most elite police organizations and hijacking a mopeds in her first attempt to "help" Jackie.
* The first appearance Dr. Rockzo The Rock n' Roll Clown on ''WesternAnimation/{{Metalocalypse}}''. Try to guess what he does [[spoiler: He does cocaine.]]:
-->Oooh ka-ka-ka-ka-ka-ka co-ka-ka-ka-yeeeaaaaah! I'm Dr. Rockzo the Rock n'Roll Clown! I do cocaine! I hear it's somebody's biiiiiirrrrrrthdayyyy! I do cocaine! Dr. Roczo's gonna make you a balloon bass! (Seriously, dude, a lot of cocaine).
* In ''WesternAnimation/{{Thundercats 2011}}'' young {{Catfolk}} Prince Lion-O is introduced [[KingIncognito sneaking]] cloaked and [[InTheHood hooded]] into the [[TheCityNarrows worst part]] of Thundera's slums, only to catch the eye of a gang of "Alley Cat" muggers who've just finished beating a hapless {{Dog|faces}}. He manages to [[MuggingTheMonster fight most off]] but has to be bailed out by ActionGirl Cheetara, to whom he reveals his reasons for being there: to find rare and obscure pieces of "[[LostTechnology technology]]," which everyone else believes to be a myth.iron
* In his second appearance in the Franchise/{{DCAU}}, Comics/{{Darkseid}} establishes exactly who he is to Franchise/{{Superman}} on their first meeting. Superman demands to know who he is and Darkseid just stands there, not saying a thing. After a little pushing, Darkseid uses his Omega Beams to torture Superman and forces him to bow down and finally responds with "''THAT'' is who I am." And thus the relationship between arguably the two most hated enemies in the entire DCAU was established.
* In the first episode of ''[[WesternAnimation/PoundPuppies2010 Pound Puppies]]'', each member of the [[FiveManBand Five Dog Band]] gets one: Yipper meets Lucky, the likable and quick-thinking leader; Cookie, the tough-but-motherly second-in-command; Niblet, the big dumb lovable oaf; Squirt, the fast-talking streetwise guy; and Strudel, the book-smart and temperamental inventor gal.
* ''WesternAnimation/TheLooneyTunesShow'': Bugs' and Lola's first date in "Members Only" establishes that show's version of her character is [[CloudCuckoolander hyperactive and a bit dimwitted,]] in contrast to her previously more grounded, StraightMan persona.
* In ''WesternAnimation/{{Wakfu}}'', [[spoiler:Qilby the Traitor]] immediately panics when he recognizes Yugo. This is the first big hint that he's actually Yugo's enemy and not a friend. When he finally and [[PowerupFullColorChange literally]] reveals his true colors, he very quickly shows that he's a totally AxCrazy lunatic.
* ''WesternAnimation/TeenTitans'':
** [[CuteAlienGirl Starfire's]] first appearance has her very cheerfully proclaiming that she is stronger than she looks...and proceeding to escape from the grasp of a villain made of cinder blocks.
** She has a second one that functions in-universe as an Establishing Character Moment for her future teammates and the audience in the origin episode "Go!". We hear her screaming in rage on-board an scary-looking alien vessel where she's being held prisoner, with the guards too afraid to deal with her. She breaks out and goes on a RoaringRampageOfRevenge both on the ship and on Earth until her future teammates calm her down, [[spoiler: kisses Robin to learn English]], and reacts with hostility to almost everything, even stating that the closest equivalent to the word "nice" on her planet is the word for "weak". This all established her as both an alien on an unfamiliar planet and a ProudWarriorRaceGirl who is extremely dangerous and unpredictable when pushed too far.
* ''WesternAnimation/{{Futurama}}'':
** In the pilot:
*** The first quarter establishes Fry's personality and status in society quite well; a kid mocks him for losing a video game, his girlfriend dumps his stuff out on the sidewalk([[IdiotHero and he still doesn't realize that he's been dumped]]), and to top it all off he realizes that he's been prank-called. When he's finally unfrozen in the future, his first reaction to his predicament is to cheer.
*** In Bender's first interaction with Fry, his recklessness is established when he waits impatiently for the suicide booth, with an attitude indicating he doesn't comprehend the implications of what he's doing. He also avoids paying for the suicide booth by putting in a coin on a string and yanking it out, establishing his criminal tendencies (and even though he won't have any use for the money once he's killed himself, further indicating that he doesn't understand what he's doing).
*** Leela kicking the crap out of two police officers when they make fun of her nose establishes her as an ActionGirl and HypercompetentSidekick.
*** Professor Farnsworth gets his after offering to make Fry, Leela, and Bender his new crew. Leela thanks him for the offer but objects that they don't have the proper career chips. Farnsworth replies "That won't be a problem! I've saved the chips from my old crew". He then gets the chips out of a folder reading "Contents of Space Wasp's Stomach".
** In "The Series Has Landed":
*** Hermes [[DissonantSerenity casually discusses all the ways Leela could die on the job with her]] while asking her to sign a liability waiver, then laughs in her face when she states that she intends to "do as little dying as possible".
*** Doctor Zoidberg's incompetence is established when he asks Fry to open his mouth in order to look at his ''brain''. When Fry complies, Zoidberg says "No, no, not that mouth".
** "Love's Labours Lost In Space" is one long ECM for [[FakeUltimateHero Zapp Brannigan]], but especially his story of how he defeated an army of rampaging Killbots:
-->''It was simply a matter of outsmarting them. [...] You see, Killbots have a pre-set kill limit. Knowing their weakness, I sent wave after wave of my own men at them, until they reached their limit and shut down.''
** Morbo's first line in the series is "Thanks, human female! PunyEarthlings were shocked today to learn that a ball of garbage will destroy their pathetic city of New New York."
* The premiere of ''WesternAnimation/StarVsTheForcesOfEvil'', "Star Comes to Earth", gives the audience two in quick succession:
** The title character, Princess Star Butterfly, is introduced [[BadassAdorable beating up monsters and wrangling wild unicorns]] [[KickingAssInAllHerFinery in a pretty dress]], wildly riding said unicorn through the streets of town and into her parents' throne room, and... [[DestructiveSavior accidentally setting her hometown on fire with her new magic wand]].
** Star's MuggleBestFriend Marco Diaz is introduced trying to convince his classmates he's being called to the principal's office because he's a "bad boy", and being sorely disappointed that the principal wants the school's resident "Safe Kid" to show the new exchange student Star around the school. Marco then rants about how he's tired of being known as "the Safe Kid" [[IResembleThatRemark while steering Star away from various minor hazards]].
* ''WesternAnimation/StevenUniverse'':
** Pearl [[MsExposition happily exposits]] on the mechanics of magic through a complicated metaphor involving [[WarriorPoet petals]] and the [[TheSmartGuy Earth's climate]].
** Amethyst steals ice cream to give it to a friend, and [[JerkWithAHeartOfGold takes pride in doing so]].
* ''Franchise/EverAfterHigh'':
** Apple joyfully pledges to follow in her mother's footsteps, and [[FriendToAllLivingThings birds land on her outstretched arms]] as she does.
** Maddie tells the narrators to stop arguing, explaining to a confused Raven that only she can [[BreakingTheFourthWall see past the fourth wall]]. Then she reassures [[EmoTeen Raven]] that people don't hate her. (Maddie's wrong, but it was still a sweet gesture.)
** Dexter asks the school outcast if he can sit with her, awkwardly stumbling over his words.
* ''WesternAnimation/{{Jem}}'':
** The first time we see The Misfits, they're riding into their managers office on [[RuleOfCool guitar-shaped motorcycles]]. They push Jerrica out of the way and then the first song of the series, "Outta My Way", occurs.
** Stormer has one where she disguises herself to help a Starlight Girl. This shows that she's the TokenGoodTeammate of the antagonists.
* In the first episode of WesternAnimation/TimothyGoesToSchool the protagonist Timothy is getting ready for his first day of school. When he goes on the bus for the first time he see's a female cat who kindly says "Hello" to him while the others are mostly quiet. This character is Yoko who would later become Timothy's best friend and is very friendly. In the same scene, he sees Doris who is viewed by Timothy to be quite annoying and loudmouthed. In the same episode, when the class introduced themselves. Charles says his not but quickly sits back down in silence due to his shyness and Lilly saying her name but thinks that's what her name is due to being very forgetful.
* ''WesternAnimation/RickAndMorty'': The series opens with Rick drunkenly trying to nuke humanity, and then half-heartedly trying to pass it off as a SecretTestOfCharacter when Morty stops him, establishing him as a DitzyGenius and HeroicComedicSociopath. However, [[EvenEvilHasLovedOnes he makes sure to save Morty from the explosion so that he could watch, and was planning to save Morty's crush Jessica so that Morty would have someone special to share the moment with]].
* ''WesternAnimation/MiraculousLadybug'': [[AnachronicOrder Chronologically]], the protagonists' responses to receiving the CallToAdventure say a lot about the heroes they eventually become. [[ShrinkingViolet Marinette]] is cautious and self-effacing- she asks a lot of questions about Tikki, and later insists that she's too cowardly to be a good Miraculous-bearer. [[LonelyRichKid Adrien]] doesn't even let Plagg finish explaining before he accepts the call, clearly relishing the chance to break free of his overbearing father.
* In ''[[WesternAnimation/MyLittlePonyTVSpecials My Little Pony: Rescue From Midnight Castle]]'', Firefly first appears doing a risky stunt which she crashes. That sets her as the most adventurous and headstrong pony around. Unsurprisingly, she's the one who goes searching for help when [[BigBad Tirek]] appears.
* ''WesternAnimation/MoralOrel'': In the first episode, Orel hears a bizarrely detailed sermon from Reverend Putty about how it's important to use the gift of life that God gave you, and [[LiteralMinded interprets this to mean that dying is a sin.]] He then proceeds to [[UnwittingInstigatorOfDoom steal the Necronomicon and raise all the dead in Moralton]], after which Clay chides him... [[SkewedPriorities for taking the clothes off the corpses before raising them]], violating the "commandment" to be ashamed of your body.
* ''WesternAnimation/{{Kaeloo}}'': Some of the characters get one in the first episode, "Let's Play Prison-Ball":
** Kaeloo remains happy for most of the episode despite all the chaos going on around her.
** [[TheDitz Stumpy]] takes the term "prison" in "prison-ball" too literally[[note]]Prison-ball is a game similar to dodgeball, except if a player is hit they get sent to a space at the back of the court called a "prison"[[/note]].
** Mr. Cat decides that prison-ball is a fun game because the game involves hitting another person and the other person going to "prison".
** Pretty the RichBitch gets one in her debut episode, where she looks down on the main four for being poor and tries to "dare" Stumpy to buy her expensive stuff during a game of Truth or Dare.
** The first scene we see with Olaf is him trying to get Mr. Cat to bow down before him while talking about [[TakeOverTheWorld world domination]].
* ''WesternAnimation/WinxClub'' gives each member (other than Bloom and Stella) their establishing moment the same scene they're introduced, when Bloom and Stella move into their suite. Flora speaks to her talking plant and gives Kiko carrots, establishing her as nature-loving and sweet; Tecna greets her with a series of facts about Bloom's planet, showing she's extremely smart but not too sociable; Musa shows she's the snarky and fun-loving one by cracking a joke about Stella blowing up the lab the year before.
** the Specialists each establish their characters in their first scene, though their personalities are established further later on: Sky is nice, Brandon is cool, Riven is difficult, and Timmy's nerdy. In season two, Helia is established as an artist and a pacifist in the first scene, which shows him drawing, and then fighting a dragon without harming it.
