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

''Nicktoons Unite!'': [[WesternAnimation/TheAdventuresOfJimmyNeutron Professor Calamitous]] joins forces with [[WesternAnimation/SpongebobSquarepants Plankton]], [[WesternAnimation/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, [[WesternAnimation/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. Released for UsefulNotes/PlayStation2, UsefulNotes/GameBoyAdvance, and UsefulNotes/GameCube in 2005, and UsefulNotes/NintendoDS in 2006.

''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 Wise Old Crab to save Volcano Island from a new villain named the Mawgu. [[DemotedToExtra Jimmy notably sits this one out and]] [[MissionControl 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 [[WesternAnimation/RenAndStimpy Stimpy]] and [[WesternAnimation/RockosModernLife Rocko]] in the console versions, WesternAnimation/InvaderZim, [[WesternAnimation/{{Catscratch}} Mr. Blik]], and WesternAnimation/ElTigre in the NintendoDS version, and [[WesternAnimation/MyLifeAsATeenageRobot Jenny Wakeman]] and [[WesternAnimation/InvaderZim GIR]] in both. It should be noted that rescued characters are only acknowledged in cutscenes in the Nintendo DS version.

''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, WesternAnimation/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 Zim as a new main character to accompany them, ''WesternAnimation/TheFairlyOddparents'' [[ChuckCunninghamSyndrome characters are oddly absent from this one.]] [[FranchiseKiller It killed the series.]]

This series was "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.
* BadassBookworm: Jimmy Neutron, especially in the first game.
* BeYourself: How [=SpongeBob=] got [[spoiler:Globulous]] to do a HeelFaceTurn. And then he shapeshifted into [[spoiler:a giant, slimy cyclops [=SpongeBob=]]]. [[BrokenAesop Uh huh]].
* BigBad: The Mawgu in "''Battle for Volcano Island''", Professor Calamitous by himself in "''Attack of the Toybots''" and [[spoiler:Globulous Maximus]] in "''Globs of Doom''".
* [[BigBadDuumvirate Big Bad Quadrumvirate]]: The Evil Syndicate, a group of Nickelodeon villains respective to each main character in the games. If the game has a Duumvirate, you can safely place your bets on them ending up as the main villains, [[spoiler:even when they seem to be helping at first]].
* 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.", referring to their encounters in the three ''Jimmy Timmy Power Hours''.
** ''Globs of Doom'' features a boss fight with Bubble Bass, a ''[=SpongeBob=]'' character not seen since the first season (with the exception of the promotional music video for the Sponge Out of Water Movie, but this was released several years after this video game.)
* CrisisCrossover
* DarkerAndEdgier: Compared to the sequels, the first 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'' and ''Attack Of The Toybots'' 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.
** The Mawgu goes from the BigBad of ''Volcano Island'' to a brief joke in the intro of ''Attack Of The Toybots''.
* DualBoss: The DS version of ''Globs of Doom'' has the infected [[WesternAnimation/InvaderZim Almighty Tallest]] as the penultimate bosses.
* EasterEgg: In ''Nicktoons: Attack of the Toybots'', the boxes for the evil teddy bears [[https://tcrf.net/Nicktoons:_Attack_of_the_Toybots_(Wii) have secret messages on their boxes that can only be found by digging in the game files]]. They say that the toys are for ages [[WhatDoYouMeanItsNotForKids 18 and up]], and were made by "[[EvilInc EvilToysCo]]". They also have extremely unnerving messages saying "[[KillerRabbit I'LL HUG YOU AND KILL YOU]]. [[NightmareFuel YOU'LL NEVER SLEEP AGAIN]]. [[AndYourLittleDogToo I'LL KILL YOUR PARENTS]]."
%%* EnemyMine: ''Globs of Doom''.
* EternalEngine:
** The near-entirety of ''Attack of the Toybots'' takes place in one.
** 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.
** 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.
* FlunkyBoss: Everyone in ''Nicktoons Unite'', and everyone but the final boss in ''Globs of Doom''. Crocker even shouts out for mooks to appear.
* GameBreakingBug: The console versions of ''Globs of Doom'' have a particularly nasty one where it causes the save files to be corrupt and unplayable, pretty much forcing the player to start the game all the way from the beginning again. This has contributed to the [[FranchiseKiller death of the Nicktoons crossover series]].
* GameplayAndStorySegregation:
** Due to not being able to choose which characters you use in ''Volcano Island'', some cutscenes have different teams from gameplay: Fetid Forest has you use a team of SpongeBob, Danny, Patrick and Sandy, but the cutscenes at the end of the level have Sam instead of Patrick, despite Sam not participating in the level. Similarly, Ancient's Peak has a team of SpongeBob, Danny, Sam and Sandy, but Patrick replaces Sam in the end-of-level cutscene.
* GiantEnemyCrab: Plankton's mecha in ''Nicktoons Unite''.
* GoofyPrintUnderwear: Knock off the skirtlike casing of one particular type of robotic enemy in ''Attack of The Toybots'', and they'll be revealed to be wearing what looks like polka-dot underwear.
* HubLevel: Jimmy's Lab in ''Nicktoons Unite'', Camp Castaway in ''Battle for Volcano Island'',[[note]]This one is a special case: Finding trinkets throughout the levels will improve everyone's homes, allowing access to bonus levels.[[/note]] and the Mawgu Lair in ''Globs of Doom''. Only ''Attack of the Toybots'' is devoid of a hub level and instead has a simple level select screen.
%%* 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.
** There's also The Great Carrapace and King Gorge in ''Battle for Volcano Island''. The former of which is to the sand monsters and the latter of which is to the Florian guards.
* LargeHam: Globulous.
-->'''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.
* 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.)
* PromotedToPlayable:
** [[WesternAnimation/SpongeBobSquarePants Patrick, Sandy]], and [[WesternAnimation/DannyPhantom Sam]] go from [=NPCs=] in ''Unite!'' to playable characters in ''Battle For Volcano Island''.
** [[WesternAnimation/SpongeBobSquarePants Plankton]] goes from being part of the FiveBadBand in ''Unite!'' to playable in ''Globs of Doom''.
* 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.
** GIR: "[[VideoGame/ZeroWing All your data are belong to MEEEEEEEEEEE!!!!!!!]]"
** Rocko: "[[WesternAnimation/{{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: "[[VideoGame/AlteredBeast Welcome to your doom!]]"
* TheSmurfettePrinciple:
** [[WesternAnimation/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.
** [[WesternAnimation/TheAdventuresOfJimmyNeutron Beautiful Gorgeous]] is the only playable female in ''Globs of Doom''.
* 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.
** To a lesser extent, Danny is usually second to [=SpongeBob=] in terms of plot importance, though that may be a tad bit justified due to being one of the few Nicktoons who regularly fights and beats up super powered baddies in his own home series.
* SuperDrowningSkills: Most apparent in ''Battle for Volcano Island'' as the characters will immediately fall through the water that isn't shallow. [[LampshadeHanging Lampshaded]] by the Wise Old Crab.
* 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''.
* 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 costume allows you to play as Dark Danny (Dan Phantom). Yes, ''that'' [[AxeCrazy Dark]] [[FutureMeScaresMe Danny]] instead of Danny Phantom.
* 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!]]"]].
