A series of multiconsole video games [[MassiveMultiplayerCrossover combining multiple cartoons]] featured on the children's TV network {{Nickelodeon}}. Actually, only the first game in this series goes by the title ''Nicktoons Unite!'', but considering all the games are about Nicktoons characters joining forces, we might as well consider it the name of the series as well.

'''Nicktoons Unite!''': [[TheAdventuresOfJimmyNeutron Professor Calamitous]] joins forces with [[WesternAnimation/SpongebobSquarepants Plankton]], [[TheFairlyOddparents Mr. Crocker]], and [[WesternAnimation/DannyPhantom Vlad Plasmius]] to form an [[LegionOfDoom Evil Syndicate]]. They start stealing energy from their respective worlds in order to power a DoomsdayDevice to [[EarthShatteringKaboom blow up the multiverse]]. To counter this, JimmyNeutron recruits WesternAnimation/SpongebobSquarepants, [[TheFairlyOddparents Timmy Turner]] (who is of course accompanied by Cosmo and Wanda), and WesternAnimation/DannyPhantom to help him venture into their worlds to stop the villains.

'''Nicktoons: Battle for Volcano Island''': Spongebob, Timmy, and Danny reunite, accompanied by co-stars [[WesternAnimation/SpongebobSquarepants Patrick, Sandy]], and [[WesternAnimation/DannyPhantom Sam Manson]], having been picked by a [[TheObiWan Wise Old Crab]] to save Volcano Island from a new villain named the Mawgu. Jimmy notably sits this one out and communicates with the heroes behind the scenes.

'''Nicktoons: Attack of the Toybots''': Professor Calamitous returns, this time planning to [[TakeOverTheWorld take over the multiverse]] with his army of Toybots, fueled by Ghost energy combined with the fart gas of fairies having been fed Krabby Patties. Spongebob, Patrick, Jimmy, Timmy, Danny, Sam, and newcomer [[WesternAnimation/TakAndThePowerOfJuju Tak]] team up to collect master models (collectibles said to hold data that Calamitous scanned from character around the multiverse that he kidnapped and then dumped (most of them) back to keep his plan secret) for the Chadbot, a robot servant of Calamitous' who claims he will help them. Along the way, they rescue starring characters from other Nicktoons, including [[RenAndStimpy Stimpy]] and [[RockosModernLife Rocko]] in the console versions, InvaderZim, [[{{Catscratch}} Mr. Blik]], and ElTigre in the NintendoDS version, and [[MyLifeAsATeenageRobot Jenny Wakeman]] and [[InvaderZim GIR]] in both.

'''Spongebob Squarepants featuring Nicktoons: Globs of Doom''': A slimy cyclops alien race known as the Morphoids and their strange orange goo envelop the Nicktoons' worlds, enslaving all innocent bystanders, so the heroes (Jimmy, Spongebob, Patrick, Danny, and Tak) join forces with the Evil Syndicate (now made up of [[WesternAnimation/DannyPhantom Technus]], [[JimmyNeutron Beautiful Gorgeous]], and [[WesternAnimation/TakAndThePowerOfJuju Traloc]], with Plankton the only "veteran" member) to get to the bottom of it. In addition, InvaderZim lies his way onto the heroes' side (claiming he's "not evil, just curious"), prompting his nemesis Dib to join the Evil Syndicate. They eventually find out the cause of it all as a result of the BigBad, an alien named Globulous, continually [[BodySnatcher body snatching]] Spongebob because he's sick of his life. In spite of having a new main character to accompany them, the ''Fairly Oddparents'' characters are oddly absent from this one. [[FranchiseKiller It killed the series.]]

This series has been "succeeded" in 2011 by '''NicktoonsMLB'''.
!!These games contain examples of:
* AdaptationalBadass: A lot of the characters in this series normally wouldn't be likely to put up much of a fight against some of the {{Mooks}} in the series, but in these games, they're all more than capable of kicking ass. Special mention goes to [[WesternAnimation/RockosModernLife Rocko]], who goes from timid everyman to being able to destroy killer toys.
* BeYourself: How [=SpongeBob=] got [[spoiler:Globulous]] to do a HeelFaceTurn. And then he shapeshifted into [[spoiler:a giant, slimy cyclops [=SpongeBob=]]]. [[BrokenAesop Uh huh]].
* BlowYouAway: Jimmy's main weapon in ''Nicktoons Unite'' is a tornado blaster, which shoots bursts of air.
* ChuckCunninghamSyndrome: Despite being one of the main characters in the first three games, Timmy, Cosmo, and Wanda are completely absent from the fourth game without a mention.
* ContinuityNod: When Timmy flirts with her in the first game, Cindy replies, "Hi Timmy. I didn't know you were back in Retroville." She's of course referring to their encounters in the three ''Jimmy Timmy Power Hours'' (Judging from her reaction, one could presume that ''Nicktoons Unite'' takes place after the third one.).
** Additionally, ''Globs of Doom'' features a boss fight with Bubble Bass, a ''[=SpongeBob=]'' character not seen since the first season.
*** And that game's [[HubLevel hub]] is a gigantic nod to ''Battle for Volcano Island''.
* CrisisCrossover
* DarkerAndEdgier: Compared to the sequels, this game is DarkerAndEdgier, both in music and threats, and with less cartoonish and comedic moments. The sequels, however, are much more LighterAndSofter.
* DemotedToExtra: Patrick. From playable character in ''Volcano Island'' to background character that spouts nonsense in ''Globs of Doom.'' Jimmy also is reduced from playable character in the first game to the VoiceWithAnInternetConnection that stays at the hub in the second, but becomes playable again for the third and fourth.
* DualBoss: The DS version of ''Globs of Doom'' has the infected [[InvaderZim Almighty Tallest]] as the penultimate bosses.
* EnemyMine: ''Globs of Doom''.
* EternalEngine: The near-entirety of ''Attack of the Toybots'', Plankton's Jellyfish Factory in ''Nicktoons Unite''.
* EverythingsBetterWithSpinning: Rocko attacks by spinning.
* FantasticVoyagePlot: The final level of ''Nicktoons Unite'' is outright called "Fantastic Voyage of Goddard"; there, the party shrink themselves to hunt down a giant fleabot inside Goddard that spies for and holds the coordinates to Calamitous' secret hideout.
** Also, the battle against the Girl-Eating Plant in ''Globs of Doom'' has you trying find a way to get swallowed by it so that you can beat up its innards.

** [[WesternAnimation/DannyPhantom Vlad Plasmius]] as TheDragon

* FlunkyBoss: Everyone in ''Nicktoons Unite'', and everyone but the final boss in ''Globs of Doom''. Crocker even shouts out for mooks to appear.
* GiantEnemyCrab: Plankton's mecha in ''Nicktoons Unite''.
* GoofyPrintUnderwear: Knock off the skirtlike casing of one particular type of robotic enemy in ''Atack of The Toybots'', and they'll be revealed to be wearing what looks like polka-dot underwear.
* ImprobableWeaponUser: A bunch in ''Globs of Doom''.
* KingMook: The giant fleabot in ''Nicktoons Unite'', which led the flea robots populating the stage you find it in.

-->'''Zim:''' HEY! [[LampshadeHanging You will not imitate ME!]]
* LegionOfDoom
* LethalJokeCharacter: The unlockable Mr. Huggles in ''Attack of the Toybots'' can kill all enemies in one hit.
* LivingToys: ''Attack of the Toybots'', duh.
* MassiveMultiplayerCrossover: Provides the page quote.
* MarketBasedTitle: The first three games were named in Europe as ''[=SpongeBob SquarePants=] and Friends'' rather than ''Nicktoons''.
* MsFanservice: Beautiful Gorgeous, [[http://3.bp.blogspot.com/_GKalpoRSdz4/SRebsIbdc5I/AAAAAAAAADU/P58ZeE06-JA/s1600-h/beaut_render.jpg and how.]]
* OriginalGeneration: Every NPC except Tucker, Squidward and Jimmy in ''Battle for Volcano Island'', and Globulous.
* PowerCreepPowerSeep: Not only does Danny get screwed big time by this trope but Calamitous, mostly an ineffectual ''Jimmy Neutron'' villain, gets bumped on the SortingAlgorithmOfVillainThreat to a Multiuniversal Threat (At first with his Evil Syndicate, and then by himself, with an army of living toys. Really.)
* PuzzleBoss: Calamitous and his pseudo-BossRush in ''Nicktoons Unite'', Cujo the Ghost Dog and the mutated Girl-Eating Plant in ''Globs of Doom''.
* RewardingVandalism: Lampshaded in ''Globs of Doom'' by the character you're controlling when you do such things.
* {{Roofhopping}}: The second Amity Park stage in ''Globs of Doom'' is set entirely atop roofs.
* ShoutOut:
** ''Attack of the Toybots'' contains "off-screen" cameo appearances by characters from almost all Nicktoons, including those that no longer air regularly (with the exception of ''WesternAnimation/{{Doug}}'' (due to legal issues with Disney), ''WesternAnimation/KaBlam'' (which will always get the short end of the stick with Nick), ''WesternAnimation/{{Pelswick}}'' (incredibly obscure), and ''WesternAnimation/TheBrothersFlub'' (Probably considered far poorly made, and also some rights issues with Sunbow), and any and Nicktoons made after the game was released, in the form of Master Models (in layman's terms, collectible items. In-universe, they're the data Calamitous has gathered from his multiversal scannings.).
*** Patrick being the character necessary to claim the Aang master model might be a nod to the famous "sea sponge" line in the ''WesternAnimation/AvatarTheLastAirbender'' episode "[[Recap/AvatarTheLastAirbenderTheSiegeOfTheNorthPart1 The Siege of the North, Part 1]]".
** GIR: "[[ZeroWing All your data are belong to MEEEEEEEEEEE!!!!!!!]]"
** Rocko: "[[{{Rugrats}} A wallaby's gotta do what a wallaby's gotta do]]... Whatever that is."
** Timmy compares Volcano Island to ''Series/{{Lost}}'' at one point.
** Zim: "[[AlteredBeast Welcome to your doom!]]"
* TheSmurfettePrinciple: [[MyLifeasaTeenageRobot Jenny]] is the only playable female character in the DS version of ''Attack of the Toybots''.
** Averted in the console versions, where [[WesternAnimation/DannyPhantom Sam]] is playable as well.
* SpiritualSuccessor: To ''Nicktoons: Freeze Frame Frenzy'' (plot-wise, at least).
** And ''Nickelodeon Party Blast'', which was released in 2003, with [[TheWildThornberrys Eliza Thornberry]], [[{{Rugrats}} Tommy and Angelica Pickles]], [[RocketPower Otto and Reggie Rocket]], Jimmy Neutron, Spongebob (duh), and ZIM as playable characters. CatDog are also in the game, but as non-playable characters.
* SpotlightStealingTitle:
** The series is titled ''WesternAnimation/SpongeBobSquarePants and Friends'' in Europe.
** Spongebob gets top billing for the fourth game, which is justified by him being a focal point of the game's story rather than a part of an ensemble cast.
* TakeYourTime: The Evil Syndicate starts up their Doomsday Machine in the pre-boss cutscene of ''Unite!'', but no timer is ever present during the fight that follows.
* TeamworkPuzzleGame: Each version of ''Unite'' is one in its own different way. Also, the GBA version of ''Battle for Volcano Island'' and the DS version of ''Globs of Doom''.
* TimCurry: The voice of Calamitous.
* TokenEvilTeammate: Zim in ''Globs of Doom''. And inverted with Dib on the evil team.
** An interesting variation of this occurs in ''Attack of the Toybots''. An unlockable feature allows you to play as Dark Danny (Dan Phantom). Yes, ''that'' [[AxeCrazy Dark]] [[FutureMeScaresMe Danny]] instead of Danny Phantom. It's presented as an alternate costume. But, still, why would Dan be helping... [[Mst3kMantra Oh, never mind...]]
* UnderTheSea: All levels set in Bikini Bottom.
* VoicesAreMental: In the case of Globulous![=SpongeBob=], first averted and then played straight after Zim's Town.
* AWinnerIsYou: In the GBA version of ''Battle for Volcano Island'', your reward for obtaining all 23 Rip-Zipper pieces and 115 Gold Hearts (which requires a NoDamageRun on every level) is [[spoiler:a giant monolith that says "Congratulations! [[OneHundredPercentCompletion You've completed the game 100%!]] [[ThankingTheViewer Thank you for playing!]]"]]. [[FlatJoy Yay.]]
