History Series / NickVerse

* ''Franchise/TeenageMutantNinjaTurtles'': In ''WesternAnimation/TheLoudHouseMovie'', a gag in a flashback sequence mentions sewer sightings of the Teenage Mutant Ninja Turtles in a newspaper, presumably the then-Nickelodeon produced ''WesternAnimation/RiseoftheTeenageMutantNinjaTurtles'' or the original show incarnation based on the time era.

* ContinuitySnarl: The concrete canon nature that iCarly, Victorious, Drake & Josh and Series/Zoey101 exist in the same reality with each other, then having the cast of ''Victorious'' say that ''Series/DrakeAndJosh'' was a tv show. This came the '''episode after''' they had Helen, a major character on ''Series/DrakeAndJosh'' show up on ''Victorious'' and reference Crazy Steve.

** Good Burger also appears in ''The Animated Adventures of Kid Danger''.

** Direct Crossover with ''Series/HenryDanger'' in the 90 minute special "Danger Games" (listed under the "Henry Danger" episode list.

* ''{{Taina}}''

** The real-world parts of ''Spongebob'' exist in the same universe as ''Series/BigTimeRush''. This is justified by Patchy the Pirate's appearance in "Big Time Beach Party."

* ''The Nick Cannon Show'' (Only reality show Nickelodeon has ever aired)

* ''The Nick Cannon Show''

* ''Series/AllThat''
** Amanda's stalker Penelope Taynt makes an appearance on the set of both ''The Amanda Show'' and ''All That''. Both appearances come in the form of backstage interactions rather than sketches
* The Nick Cannon Show

** A sketch from The Amanda Show can be heard playing in the Drake and Josh episode Dune Buggy. Since The Amanda Show is a [[ShowWithinAShow show within a show]], viewers in the Drake & Josh universe are seeing only the monologues and sketches. The backstage story arcs (with Creator/DrakeBell and Creator/JoshPeck) and those involving Penelope Taynt are part of the [=NickVerse=]

** Amanda's stalker Penelope Taynt makes an appearance on the set of both The Amanda Show and All That. Both appearances come in the form of backstage interactions rather than sketches

** The episode "Latanya, Girl Where You At?" features Latanya from an All That sketch

** Main character Addie Singer appears in a clip with Megan Parker in the Drake & Josh episode "''Honor Council''"

** However, In the episode "Game Shippers", ''iCarly'' is referred to as a television show, and Nathan Kress is approached AsHimself to determine who Freddy's true love interest was.

We know that [=SpongeBob=] exists as a show within the secondary [=NickVerse=] because Patchy the Pirate is a big fan of the show. Because of this, the following shows all potentially existing with their own [=NickVerse=]:

On April 21, 2022, Nickelodeon is set to the air its biggest crossover yet: a ''Series/SideHustle'' special titled When Worlds Collide (originally titled That Young Warped Danger Hustle), a crossover between 5 of Nick's current sitcoms.

** The only series in either the Nick Verse or the Disney Channel equivalent that officially exists in the 'Verse that's either not a KidCom (it's a cooking show) ''and'' is televised and produced on a completely different network (the unrelated Creator/FoodNetwork which is owned by a completely different conglomerate from CBS/Viacom, which owns Nick). Several shows have featured the Hungry Girl website including ''iCarly'' (including in its intro sequence) and ''Henry Danger'' (it's shown on the [=PearBook=] in the example discussed above). It's also a part of the Recursive Canon as Miranda Cosgrove has appeared as a special guest on the show for a recipe for (naturally) spaghetti tacos. The reason why this show is officially acknowledged in the Nick Verse is because Dan Schneider is married to the eponymous Hungry Girl in real life (so it's meant as a ShoutOut, but it's prevalent enough that it manages to link itself to the 'Verse at the same time).

** A direct crossover with ''Series/HenryDanger'' in the episode Knight and Danger. It should be noted that this series is located in an alternate reality from ''Series/HenryDanger''.

** Latanya exists in this universe, but is merely a sketch character in All That. This could mean that the whole Nick Cannon Show exists within the universe of a single All That sketch

[[AC:Series which exist in a secondary Series/NickVerse (may or may not be connected to the primary Series/NickVerse):]]

** One Direction exists in Big Time Rush and iCarly.

** Yo Gabba Gabba makes a cameo in Big Time Rush episode "Big Time Cameo". The two groups meet backstage, but the Yo Gabba Gabba characters continue to act as if they are in a children's edutainment show. This suggests that Big Time Rush is interacting with the actual Yo Gabba Gabba characters, and they live in a universe where the Yo Gabba Gabba characters exist offstage.

** The characters in the show run into Yo Gabba Gabba characters in the episode "Trapped in Paris". Again, Yo Gabba Gabba act like themselves despite being in a non-performance environment. This suggests that they are interacting with the actual Yo Gabba Gabba characters rather than their actors (i.e. they are talking to DJ Lance Rock rather than Lance Robertson)

** Since minor characters from the show Big Time Rush do not appear, we can't determine whether this is the real-world band or the fictional band

We know that [=SpongeBob=] exists as a show within the secondary Nick Verse because Patchy the Pirate is a big fan of the show. Additionally, [=SpongeBob=] exists in the same universe as the following shows:

* ''WesternAnimation/{{Futurama}}'': Crossed over with The Simpsons, with Bender continuing to be in their basement.

* ''WesternAnimation/StarVsTheForcesOfEvil'': Cameos of Gravity Falls characters.
* ''WesternAnimation/ThePowerpuffGirls2016'': Proven to be a continuation of the original show in a cutaway gag of characters in the old style.

[[AC:Actors who play multiple characters in the Nick Verse]]

* ProlongedPrologue: Since 2016, it is normal for Nick's sitcoms to have long cold opening, typically taking between 5-10 minutes for the theme song to start playing. Warped!'s cold openings are much shorter than other modern Nickcoms (although still long for kidcom standards).
* RecursiveReality[=/=]RecursiveCanon[=/=]MutuallyFictional: Probably averted (probably because of how complex these tropes are). Even though Series/DrakeAndJosh exists in the same universe as the rest of the shows (as can be seen above) the Series/{{Victorious}} episode ''Who Did It To Trina'' has the characters come out and say that Series/DrakeAndJosh was a TV Show. Despite this, neither of these tropes probably (again, complex) apply.
* YouLookFamiliar: In the Victorious/iCarly crossover, Freddie remarks that Tori looks like Shelby, but that Tori is hotter.

** In one episode, Carly is seen watching ''Series/DrakeAndJosh'', and commenting about the character Megan. (Both Carly and Megan are played by Creator/MirandaCosgrove)

** As with ''Series/DrakeAndJosh'', the show is listed on Carly's TV in the aforementioned episode.

!!Tropes constant across the Series/NickVerse.

The Nick Verse was generally not based around deliberate crossovers, until ''Series/{{Victorious}}'' began. Before ''Series/{{Victorious}}'', a [[ThrowItIn blasé approach]] to continuity led to a melding of some quite complicated RecursiveCanon[=-=]esque elements in certain Nick shows. An animated Nickverse also exists and may be part of the live-action Series/NickVerse.
