->''"Oh, please. If there were new guys, they'd have shown up in the season premiere."''
-->-- '''[[MetaGuy Denny Crane]]''', ''Series/BostonLegal''

The series {{Pilot}} has to do a lot of things. It has to establish the main character, set up the central conflict, and [[RealLifeWritesThePlot convince the network execs to okay the series]]. Usually, you can introduce all of the main characters in this process.

Occasionally, though, a secondary character can't quite get shoehorned into the introductory story and just doesn't exist in the pilot. Alternately, sometimes the networks execs approve the show, but decide that it needs a few extra characters, so the creators introduce these characters in the next episode. Sometimes, cast members show up for a PilotMovie but don't agree to come back for the series.

Any of these qualify as the Second Episode Introduction. The key characteristic is that whoever is being introduced must show no signs of existence in the pilot, and must be a regular cast member from that point onwards.

A character who is introduced in the second episode as a replacement for a very similar character who appears only in the pilot is a SecondEpisodeSubstitute. For a series that introduces multiple regular characters over its first few episodes, see DebutQueue. A character introduced in a sequel movie, or after season one of a series, is an IconicSequelCharacter.


[[folder: Anime and Manga ]]

* The first episode of ''Anime/{{Pokemon}}'' had Ash, Pikachu, and Misty but Team Rocket didn't show up until the second. (Brock, who outlasted Misty's presence in the anime by several seasons, doesn't appear until episode five.)
* In ''Anime/{{Hamtaro}}'', Dexter, Howdy, Pashmina and Penelope are introduced in the second episode.
* In ''Anime/LeChevalierDEon'', two of the main characters don't appear until the second episode.
* [[GreatDetective L]] in the ''Manga/DeathNote'' anime, as the first episode ends with Light first deciding to become Kira.
* All but one of the main protagonists in ''Anime/GaReiZero'' are introduced in the second episode. The first episode is filled with [[DecoyProtagonist decoy protagonists]].
* Asuna in the anime adaptation of ''LightNovel/SwordArtOnline''.
** Technically we see her in the first episode when all the players were rounded up, but she didn't actually say anything.
* In ''Manga/StrawberryMarshmallow'', Ana's second ''volume'' introduction becomes ''this'' in the anime adaptation, thus adding her to a couple of stories she wasn't originally in: the first one with the kitty hat, and the BeachEpisode.
* ''Manga/KimiToBoku'': Misaki is introduced in the second.
* Because ''Manga/ShinryakuIkaMusume'''s episodes are divided into ThreeShorts, who qualifies for this depends on how you look at it. The spirit may be exemplified by Takeru, the younger brother of the Aizawa sisters, introduced in "Aren't We Brothers-in-Arms?", the second part of the first episode. Characters introduced in the literal second episode: Goro the Life Saver, in "Aren't We Squids of a Feather?" and Sanae, in "Want to Swim Out and Play?"
* Pepper and Salt were introduced in the second episode of ''Anime/ALittleSnowFairySugar'', showing us that there are ''other'' apprentice season fairies.
* In ''Anime/TenchiMuyo'', the first episode introduces Tenchi, his grandfather and Ryoko. Ayeka and Sasame don't get introduced until the second episode. Either subverted or taken {{up to 11}} depending on your viewpoint, when Mihoshi is introduced in episode 4 and Washu fills out Tenchi's {{harem}} in episode 6.
* ''Anime/TheIdolmasterCinderellaGirls'' focuses on two characters in the first episode, out of a main cast of fourteen. The rest of them are properly introduced in the following episode.
* Rui plays a very important role in ''Anime/GatchamanCrowds'', being the one responsible for both materializing and directing the titular [[SoulPoweredEngine CROWDS]] that appear in the story. He also gets heavily involved in the conflict due to the antagonist's interest in manipulating him for his own goals. Despite all of this, he doesn't get officially introduced until the end of episode 2 at which point he starts getting regular screen time afterward.
* The second episode of ''Manga/HajimeNoIppo'' introduces Genji Kamogawa (the titular hero's mentor and owner of the gym he trains at), Ichiro Miyata (TheRival), and the latter's unnamed father.
* The second episode of ''Manga/SlamDunk'' introduces Takenori Akagi, Kiminobu Kogure and the rest of the Shohoku Basketball team. Akagi and Kogure are respectively TheTeam's captain and vice captain.
* The second episode of ''Anime/MobileFighterGGundam'' introduces TheLancer Chibodee Crockett and his FourGirlEnsemble crew.
* The second episode of ''Anime/MobileSuitGundamWing'' introduces Catherine Bloom, the CoolBigSis figure to one of the protagonists.
* ''Anime/MobileSuitGundam'' waits until its second episode to introduce Sayla Mass, Kai Shiden, Mirai Yashima, and Ryu Jose.
* Justified in ''Anime/{{Sabagebu}}'', where Sakura's defining character trait is clumsiness so extreme that it frequently results in her missing school. It takes a few days for her and Momoka to actually meet for the first time.
* In the 1968 series of ''Anime/GeGeGeNoKitaro'', Nezumi Otoko doesn't appear until the second episode.


[[folder: Comics ]]

* April O'Neil did not appear until the second issue of ''Comicbook/{{Teenage Mutant Ninja Turtles|Mirage}}''.
* ''ComicBook/SpiderMan'''s J. Jonah Jameson is somewhat of an example: Although his first appearance is in the first issue of "Amazing Spider-Man," this is actually the second ever Spider-Man ''story'' due to the first being in ''Amazing Fantasy.''
* ''ComicBook/TheTransformersMoreThanMeetsTheEye:'' The first issue introduces most of the supporting cast, except Skids, who doesn't show up until issue 2 (he was going to appear in issue 1, but there wasn't enough room).


[[folder: Film ]]

* Leo Barnes does not appear in ''Film/ThePurge'', making his first appearance in [[Film/ThePurgeAnarchy the sequel film]] and becoming TheHero of the film franchise afterwards.
* Charles Robinson has been present in all the ''Film/JamesBond'' films during the Creator/PierceBrosnan era except [[Film/GoldenEye Brosnan's debut]]. He's eventually struck with ChuckCunninghamSyndrome once Creator/DanielCraig takes over.
* Roman Pierce and Tej Parker aren't introduced in ''Film/TheFastAndTheFurious'' film franchise until the second film.
* ''Film/BatmanVSupermanDawnOfJustice'', the second installment of the ''Franchise/DCExtendedUniverse'', introduces Batman, Wonder Woman, Lex Luthor, and Alfred Pennyworth, plus {{Early Bird Cameo}}s from The Flash, Aquaman, Cyborg (all via videos), Steve Trevor (via photo), and Steppenwolf (in a DeletedScene).
* Sweet shop owner Louie Dumbrowski makes his debut in the second Bowery Boys movie, ''In Fast Company'' (actor Bernard Gorcey did appear in a small part in the first Bowery Boys movie ''Live Wires'').
* ''Franchise/StarWars'':
** Neither Yoda nor the Emperor appear in ''[[Film/ANewHope A New Hope]]'' (although the latter is mentioned in the opening briefing regarding the Death Star), making their first appearances in ''Film/TheEmpireStrikesBack''.
** In the Original Trilogy, the PowerTrio of Luke Skywalker, Han Solo, and Princess Leia was established in ''Film/ANewHope''. Then ''Film/TheEmpireStrikesBack'' introduced Lando Calrissian as something of a fourth member of the trio, who continued to be an important supporting role in ''Film/ReturnOfTheJedi''.
** In the Sequel Trilogy, there is no strongly-defined trio, but heroes Rey and Finn, Resistance hero Poe Dameron, and villain Kylo Ren are all established as the main new characters that will carry the trilogy. Then ''Film/TheLastJedi'' introduces Resistance grunt worker Rose Tico and propels her to the role of another major protagonist for the duration of the film.


[[folder: Literature ]]

* Master Geppetto is introduced in the second chapter of ''Literature/TheAdventuresOfPinocchio'' to take the log of wood and convert it into Pinocchio.
* ''Literature/ChronoHustle'': The first story only introduced one main character, Jack Masterson. In the second, Melinda Summers was introduced, along with the organization she works for, the TRD.
* ''Literature/TanteiTeamKZJikenNote'':Second Scene Introduction to be exact. Most of the cast has been introduced in the first chapter when they Crash-Into Hello, but Kozuka is only introduced at the Special Class classroom.


[[folder: Live Action TV ]]

* In the Scifi series ''Series/TheInvisibleMan'', the Keeper shows up in the second episode. This seems to be the second type, because it would have been easy to work her character into the pilot.
* Matt Parkman in ''Series/{{Heroes}}'', who in a variation was originally intended to be in the pilot, but whose introduction was delayed until the second episode instead.
* "The Corbomite Maneuver", the first non-pilot episode of ''Series/StarTrekTheOriginalSeries'', introduces Uhura, Yeoman Rand, and Dr. Leonard "Bones" [=McCoy=] (as a SecondEpisodeSubstitute for Dr. Mark Piper); it is not, however, the second episode aired, as the pilot episode "Where No Man Has Gone Before" was held back until later in the first season. Counting both pilot episodes, "Where No Man Has Gone Before" being the second pilot introduces Kirk, Sulu, and Scotty; Spock was the only main crewman there from the very beginning in the original pilot, "The Cage."
* "Past Prologue," The first post-pilot episode of ''Series/StarTrekDeepSpaceNine'', introduces [[TheSpymaster Garak]]. Originally meant to be a one-shot character, he becomes the EnsembleDarkhorse.
* JJ of ''Series/CriminalMinds'', who is later shown to be an integral part of the team, isn't present or even mentioned in the first episode.
* Godber and all other prisoners except Fletcher himself do not appear in the pilot of ''Series/{{Porridge}}''.
* Dylan [=McKay=] is conspicuous by his absence in the pilot for ''[[Series/BeverlyHills90210 Beverly Hills, 90210]]'' (yes, the title had a comma in the pilot's opening credits), showing up from episode 2.
* Clyde Langer did not appear until the second episode of ''Series/TheSarahJaneAdventures'', replacing [[TheScrappy Kelsey]] in an inversion of AffirmativeActionGirl.
* Betty Draper appears for maybe two minutes in the pilot of ''Series/MadMen''--series creator Matt Weiner actually had to write extra scenes for the audition process, which were later incorporated into an episode. Naturally, Betty became a major character from the second episode onward.
* ''Series/EliStone'' didn't introduce Maggie, a main love interest and Eli's partner, until the second episode.
* Brooke Davis on ''Series/OneTreeHill'', who quickly became an EnsembleDarkhorse and one of the show's leads.
* On ''Series/{{Community}}'', Señor Chang does not appear until the second episode. Additionally, Prof. Buzz Hickey and Elroy Patashnik are only introduced in the second episodes of their respective seasons as guest regulars.
* Rather than a character, ''Franchise/PowerRangers'' often holds off on debuting either the Megazord or even the TransformationSequence until the second episode of a two-part premiere. Sometimes they do both in a two-stage version: air both parts of the premiere on the same day with the first transformation happening in the second half, then bring out the mecha in next week's episode. Some premieres also show some of the team morphed in the first episode, but wait until the second to let the entire team transform.
** The first season of ''Series/MightyMorphinPowerRangers'' averted this in its adaptation of ''Series/KyoryuSentaiZyuranger'': in the original series it took several episodes for Daizyuzin (the Megazord) to be introduced, but it was an integral part of the Rangers' arsenal in ''MMPR'', so a later mecha fight was moved up to the first episode.
** In ''Series/PowerRangersLightspeedRescue,'' we don't meet monster-maker Jinxer until episode two (which is interesting - he wasn't there when the villains were unsealed, so was he on Earth all along?)
** In ''Series/PowerRangersTimeForce'' we don't meet Red Ranger and main character Wes until the second episode. The first episode does, however, feature his look-alike descendant (played by the same actor).
** ''Series/PowerRangersDinoCharge'' waits until episode two to introduce Riley, even though the rest of the team all appeared in the first episode.
* ''Series/NewGirl'''s Winston was introduced in the second episode, replacing the suddenly-absent roommate Coach.
* In ''Series/DropTheDeadDonkey'', Sally Smedley first appears in the second episode. {{Justified|Trope}} as a personnel decision by the new CEO.
* ''Series/DoctorWho'' introduced iconic supervillains the Daleks in the second story. However, this is an inverted trope, as this was much earlier than the staff had originally intended to introduce the alien villains.
* District Attorney Adam Schiff (Steven Hill) of ''Series/LawAndOrder'' is notable in that he appeared in EVERY EPISODE of the first 10 seasons EXCEPT for the first one, which was produced before Hill had joined the cast. Since the episode was shown out of sequence, the audience saw five episodes with Hill, one with Roy Thinnes (and a completely different opening montage) and then back to Hill the next week.
* Chad Dylan Cooper doesn't appear until the second episode of ''Series/SonnyWithAChance''.
* Sloan Sabbith isn't introduced until the second episode of ''Series/TheNewsroom''.
* ''Series/TheWalkingDead'':
** Andrea, T-Dog, Merle, Jacqui and Glenn, though the last one's voice was heard in the final scene of the pilot episode via radio.
** Hershel, Maggie, Beth, Otis, Patricia and Jimmy were introduced in the second episode of the second season.
** Father Gabriel Stokes and the Hunters were introduced during the second episode of Season 5.
** Denise Coyd was introduced during the second episode of Season 6, along with other characters [[WeHardlyKnewYe who did not make it at the episode's end]].
** King Ezekiel and the rest of the Kingdom were introduced during the second episode of Season 7.
* In ''Series/{{Glee}}'' we don't meet Brittany until the 2nd episode of the series. Seeing Quinn and Santana without Brittany is...odd to say the least
* Don Flack wasn't in the PoorlyDisguisedPilot of ''Series/{{CSI NY}}'' that aired on ''Series/CSIMiami''. His character was created after the pilot and first appeared in NY's first ep of its own, 'Blink'.
* Detective Marcus Bell isn't in the pilot of ''Series/{{Elementary}}'', but he's appeared in every episode since.
* The ''[[Series/SpartacusBloodAndSand Spartacus]]'' series:
** The titular character didn't arrive at the ludus until the second episode, so all of the major characters there such as Doctore Oenomaus, Naevia, Ashur, Varro, Rhaskos, Gnaeus, Rabanus, and Pietros were all introduced there.
** Nasir and Chadara made their debut on the second episode of Season 2.
** Caesar, Laeta and Sybil were introduced during the second episode of the final season.
* ''Series/BreakingBad'''s fifth season introduces Lydia in the second episode.
* In ABC's short-lived ''Series/MindGames'', Samantha Gordon was not introduced until the second episode.
* ''Series/{{Revolution}}'' doesn't reveal that [[spoiler: Charlie's mother Rachel is alive]] until the second episode. In this case, the reveal was filmed for the first episode but the character was later recast so the scene was taken out and re-filmed in time for the second episode's airing.
* In ''Series/{{Psych}}'', main cast member Juliet isn't introduced until the second episode.
* ''Series/GameOfThrones'':
** Irri, Dorreah, Ilyn Payne and Rast were introduced in the second episode of the entire series.
** Balon Greyjoy, Yara Greyjoy, and Salladhor Saan were introduced in the second episode of the second season. After appearing as a LastEpisodeNewCharacter in Season 1, Jaqen H'ghar was officially introduced here, though it is heavily implied that the one who appears later is a different character using the same face.
** Olenna Tyrell, Orell, Locke and Ramsay Snow/Bolton were introduced during the second episode of Season 3.
** Mace Tyrell was introduced during the second episode of Season 4.
** Doran Martell and Areo Hotah were introduced during the second episode of Season 5.

** The second episode of the series introduces recurring villain China White and TheHero's very first mentor Yao Fei.
** Recurring villain Bronze Tiger does not appear until the second episode of the second season.
** Recurring villain Anarky does not appear until the second episode of the fourth season.
* ''Series/TheFlash2014'':
** Harrison "Harry" Wells and Patty Spivot do not appear until the second episode of the second season.
** Julian Albert is introduced in the second episode of the third season. Justified, because it's a result of Barry trying the fix the timeline.
* In ''Series/{{Supergirl 2015}}'', [[HeelfaceRevolvingDoor recurring]] [[FriendlyEnemy frenemy]] Maxwell Lord does not appear until the second episode of the series.
* ''Series/{{Daredevil 2015}}'':
** Season 1's first episode introduces us to protagonists Matt Murdock, Foggy Nelson, and Karen Page as well as antagonists James Wesley and Leland Owlsley. The second episode introduces Claire Temple to the cast.
** Season 2's first episode introduces Frank Castle. The second episode introduces Samantha Reyes[[note]]Sorta; it's her first appearance in ''Daredevil'' but Reyes had first been introduced in the season finale of ''Series/JessicaJones2015''[[/note]] and Blake Tower.
* ''Series/JessicaJones2015'': Kilgrave makes his first physical appearance in the second episode and we first see his face in the third episode.
* The second episode of ''Series/PennyDreadful'' introduces main characters Brona Croft, Dorian Gray and the Creature, the latter only shows up at the very end. Interestingly the same episode introduces [[spoiler:Madame Kali]] who only becomes important in the second season.
* In ''Series/BetterCallSaul'':
** Nacho Varga was first introduced in the second episode of season 1.
** While Kim Wexler makes a brief appearance in the season 1 pilot, and a brief cameo in the second episode, she's not given a proper introduction until the third episode.
* ''Series/OrphanBlack'':

[[folder: Visual Novel ]]

* ''Franchise/AceAttorney'' manages to do this ''[[UpToEleven with every game]]'' due to the first case being a tutorial. Many important characters, including TheRival, are not introduced until the second case of each game. These include:

Bubs and Coach Z were introduced in the second story, "Where My Hat Is At?", and other characters came later.
* Early episodes of ''Series/{{Noob}}'' were less than five minutes long, hence it took three of them to introduce all four main characters (plus a ChekhovsGunman or two).
* The first ''Literature/ChronoHustle'' story only introduced one main character, Jack Masterson. In the second, Melinda Summers was introduced, along with the organization she works for, the TRD.

* In ''WesternAnimation/KidVsKat'', Dennis, Lorne, and Harley don't show up until the second episode, "Night of the Zombie Kat".

* Gus and Miss Grotke are introduced in ''WesternAnimation/{{Recess}}'' not in the second episode, but part B of the first episode. For the former, it was his WelcomeEpisode. For the latter, it was more "She wasn't in the first part, so here she is".
* Dr. Van Goosewing first properly shows up in the second episode of ''WesternAnimation/CountDuckula'', "Vampire Vacation." He technically appeared in the first episode though, due to the OutOfOrder pilot episode.

** Like in the original comic, April is absent until the second episode of ''WesternAnimation/TeenageMutantNinjaTurtles2003''. It's the only time an animated adaptation excludes her from the pilot episode.
