A MassiveMultiplayerCrossover subseries of Namco's ''[[TalesSeries Tales of]]'' series. Two of them, actually, under different subtitles.

-----
!!''Narikiri Dungeon''
The first subseries is the ''Narikiri Dungeon'' series, which itself is a {{spinoff}} from a sequel to ''VideoGame/TalesOfPhantasia''. The series' key feature is the ability of the OriginalGeneration main characters to "[[{{Cosplay}} dress up]]" as various character classes (Fighter, Thief, Mage, etc.) and gain new powers depending on which role they are portraying. Their wardrobe includes the outfits of various ''TalesSeries'' heroes and villains, and even [[LawyerFriendlyCameo cameos]] from various NamcoBandai games.

''Narikiri Dungeon 2'' (2002) and ''Narikiri Dungeon 3'' (2005), both developed by Alfa System, revolve around a pair of youngsters named Calo Olange and Frio Sven, who must wander the Tales pseudo-timeline and prevent it from being mucked up. ''Narikiri Dungeon 3'' incorporated tactical elements, allowing you to recruit all the ''Tales'' heroes, arrange them into four teams of up to three each, and move them around the map to solve puzzles and administer a collective beatdown to the boss.

''Narikiri Dungeon 2'' includes characters from ''VideoGame/{{Tales of Phantasia}}'', ''VideoGame/{{Tales of Destiny}}'', and ''VideoGame/{{Tales of Eternia}}''. ''Narikiri Dungeon 3'' includes all those, plus ''VideoGame/{{Tales of Destiny}} 2'' and ''VideoGame/{{Tales of Symphonia}}''.

'''''Narikiri Dungeon'' provides examples of:'''

* BonusDungeon: ''Narikiri Dungeon 3'' has one like ''TheTowerOfDruaga'' but shorter.
* ByThePowerOfGreyskull (Parodied when Frio and Calo try to come up with one.)
--> '''Frio''': Narikiri Change! Narikiri Illusion! Narikiri Henshin!
--> '''Calo''': Narikiri [[CuteyHoney Cutey Flash! Kawaru wa yo~n]]!
* OriginalGeneration
* ShoutOut: Lots and lots.
* TimeTravel: A surprising amount over all the games.

-----
!!''Radiant Mythology''
The second subseries is the ''Radiant Mythology'' series for the {{PSP}}. There are currently three games in the series, all developed by Alfa System, with the roster of available ''Tales'' characters increasing substantially with each new title.

The ''Radiant Mythology'' series takes place in a [[TheMultiverse multiverse]] of worlds, each with their own WorldTree. When a World Tree senses a threat to its world, it creates a warrior called a Descender as a defence mechanism. In each game you take the role of a Descender, and you must join up with the rest of the TalesSeries characters to battle whatever is threatening the future of your home world. Joining you is an [[OriginalGeneration original character]] named Kanonno, appearing [[InexplicablyIdenticalIndividuals as a different incarnation]] in each game: [[spoiler:Pasca]] Kanonno in the first (2006), Kanonno Earharts in the second (2009) and Kanonno Grassvalley in the third (2011).

Gameplay revolves around accepting quests from Ad Libitum, a HeroesRUs guild run by a multitude of TalesSeries characters. The game uses a ClassAndLevelSystem for your character, along with [[PrestigeClass Elite/Advanced Classes]]. Really though, it's all a RuleOfFun excuse to team up with your favourite characters and watch them interact in skits.

-----
'''''Radiant Mythology'' provides example of:'''
* AlternateUniverse: The Tales characters in each world are from that world (or a similar parallel world), with alterations in back story to keep their personalities intact while integrating them into the larger scenario. This becomes complicated when they need to justify [[VideoGame/TalesOfDestiny 15-year-old Kyle interacting with his 19-year-old father]], or [[VideoGame/TalesOfPhantasia Suzu]] joining the guild alongside her [[VideoGame/TalesOfSymphonia 4000-years-hence ancestor, Sheena]].
** However, some of them are more welcome. Fans of Asch and Luke would be more pleased primarily because in this universe, the two are brothers, albeit still very vitriolic. This keeps them both alive, giving both of them a happy ending.
* AmnesiacDissonance: In [=RM1=], [[spoiler:Kanonno remembers that she was once on the same team as Widdershin and actually came to Terresia to help him assimilate it into Gilgulim]].
* AnAdventurerIsYou: Due to being able to change classes, the Descender can run the gamut from being a SquishyWizard to a MightyGlacier.
* ApronMatron: ''[=RM2=]'''s mascot, Paneer.
* AssimilationPlot: [[spoiler:Widdershin intends to absorb every single world into Gilgulim, creating an eternal but solitary world.]]
* BadassArmy: Ad Libitum seemed like a BadassCrew in the first game, what with the small amount of named characters but they actually have an army behind them. The second and third games border on this, with SIGNIFICANTLY more members being added each game.
* BattleButler: ''[=RM3=]'''s mascot, Rocksprings, taught Kanonno to wield a sword. Plenty more where that came from.
* [[spoiler:ButNowIMustGo: Supposedly the ultimate fate of every Descender after completing his/her mission is to be re-assimilated into the World Tree... but that doesn't prevent him/her from coming back for a PlayableEpilogue.]]
* TheChosenOne: The player steps into the shoes of the "Descender" who was created by the WorldTree to protect the world from whatever threatens it.
* CoolAirship: From the second ''Radiant Mythology'' onwards, [[VideoGame/TalesOfEternia Chat's]] ''Van Eltia'' serves as the Ad Libitum guild's home base. It TookALevelInBadass here, as it now houses amenities for over eighty people and an onboard shop.
* DarkMessiah: Lazaris in [=RM3=] masquerades as the Descender of Luminasia. [[spoiler:She's actually Jildia's equivalent of a Descender]].
* {{Deconstruction}}: This is often par for the course for the ''Tales'' series but ''Mythology'' still has a pretty horrible deconstruction of TheChosenOne. Basically, Descenders are created to save their worlds, ''no matter what''. In fact, [[BecauseDestinySaysSo it's implied that they don't have any true "free will" of their own - being eternally bound to their mission to protect their world]]: it's literally all they have. That alone is pretty bad but it gets worse as [[WellIntentionedExtremist some of the Descenders]] [[KnightTemplar get a bit too hardcore]] [[UtopiaJustifiesTheMeans about saving their worlds]].
* DespairEventHorizon: [[spoiler:Kanonno]] in [=RM1=], [[spoiler:after her homeworld of Pasca was consumed by war and all her efforts as its Descender failed miserably]].
* DiscontinuityNod: Subverted in ''[=RM3=]'', where a puzzle element listing the main-series Tales games in order includes ''[[VideoGame/TalesOfTheTempest Tempest]]'' right behind ''[[VideoGame/TalesOfTheAbyss Abyss]]''.
* EasilyForgiven: In [=RM1=], you learn that [[spoiler:Pasca Kanonno]] worked for the other side and has pretty much committed genocide. On multiple accounts [[spoiler:if you count all the worlds she helped Widdershin feed to Gilgulim]]. But none of that matters apparently because you're friends. [[spoiler:Oh, and don't forget that she tried to destroy the city right before her boss battle with you.]]
* ExpositionFairy: Mormo in the first game, Niata Monad in the second. Paneer and Rocksprings, from ''[=RM2=]'' and ''[=RM3=]'' respectively, politely stay the hell out of the players way most of the time.
* {{Expy}}: Two notable ones.
** Widdershin, the BigBad of the first game, looks a heck of a lot like [[FinalFantasyVII Sephiroth]]. Their motives, however, are completely different (Seph wants [[AGodAmI to be a god]] and [[OmnicidalManiac destroy the world]], while Widdershin wants to preserve the worlds [[spoiler:by merging them into one]]). [[FanDumb Certain members]] of the ''VII'' fanbase don't see it that way, though; leading to a ''lot'' of FanWank.
** Kanonno looks alot like [[ShugoChara Amu]], particularly Kanono Earheart - who has gold eyes and [[KanaeIto the same voice actress]].
* GeniusLoci: The worlds themselves border on this, what with a WorldTree that can actively sense danger and conjure sentient defenses. [[spoiler:Jildia]] in ''[=RM3=]'' plays it more straight, bordering on EldritchLocation.
* GoneHorriblyRight: So if a world is on the brink of destruction, its WorldTree creates a Descender whose entire purpose is to save the world no matter what. [[WhatCouldPossiblyGoWrong How could that possibly end badly?]] [[spoiler:Oh hi there, Widdershin, Aurora and Pasca. Lazaris joins too.]]
* GratuitousLatin: Possibly spoofed by the Descender's guild's name, "Ad Libitum."
* HeroicMime: The Descender himself/herself. In [=RM1=], Mormo does all the talking.
* InexplicablyIdenticalIndividuals: Each entry features its own new Kanonno, not entirely unlike the old Kanonno. This is HandWaved in ''[=RM2=]'' but becomes a plot point in ''[=RM3=]'', where all three appear. Each has a season theme, and even the same [[LinitBreak Mystic Arte]]. They all differ , however, in their focus.
** [=RM1=]: [[spoiler:Pasca]] Kanonno (voiced by Haruka Kudo) (Winter Kanonno, [[SquishyWizard focused more on magic]].)
** [=RM2=]: [[KanaeIto Kanonno Earhart]] (Summer Kanonno, [[MightyGlacier focused more on physical attacks]].)
** [=RM3=]: [[Creator/AyaHirano Kanonno Grassvalley]] (Autumn Kanonno, JackOfAllStats)
* KilledMidSentence: [[spoiler:Niata Monad appears for all of two minutes]] in ''[=RM3=]'' [[spoiler:before being sniped from off-screen by Lazaris]].
** [[spoiler: He gets better though upon returning to the site where he was shot down, and soon joins Kanonno on the bridge of the Van Eltia.]]
* TheHeartless / HumanoidAbomination: Goede, BigBad of [=RM2=], is a personification of the negative emotions of the people of Granide.
* HeroesRUs: Ad Libitum, a heroic organization. The first game had only nineteen main Tales characters, with the rest of the organization being nameless RedShirts and the occasional DeskJockey, with quests being taken up by groups of four. The later games combine this with elements of organization of heroes, with EVERY member being a bonafide {{Badass}}, except for the shopkeepers, who decided that [[GenreSavvy supplying weapons and equipment for a large group like that will be a profitable adventure.]]
* LinearWarriorsQuadraticWizards: From ''Radiant Mythology 2'' onwards, magic is [[{{Nerf}} nerfed]] significantly... but [[VideoGame/TalesOfInnocence Iria]] is ''still'' quite the powerhouse.
* MassiveMultiplayerCrossover
* MythologyGag: A puzzle in the Almanac Ruins in ''[=RM3=]'' involves tracing out a word on a series of alphabet panels ([[spoiler:RADIANT]]), in a direct homage to ''[[VideoGame/TalesOfDestiny Destiny 2]]''. The original solution can also be spelled out.
* OneSteveLimit: Each game has its own version of Kanonno: [[spoiler:Pasca]] Kanonno for [=RM1=], Kanonno Earhart for [=RM2=], and Kanonno Grassvalley for [=RM3=]. In [=RM3=], however, all three of them can be in your party!
* OriginalGeneration: A few, most prominent of which are three pink-haired 15-year-old girls sharing the name "Kanonno". There are also the {{Big Bad}}s: Widdershin for [=RM1=], Goede for [=RM2=] and Lazarus for [=RM3=].
* PrettyInMink: The berserker armor has a tiger skin worn as a ShowgirlSkirt.
* [[spoiler:SpinOffspring]]: In ''[=RM2=]'', [[spoiler:Granide is the world born at the end of ''[=RM1=]''.]]
* [[spoiler:TheTimeTravelersDilemma]]: [[spoiler:The Pasca Kanonno making an appearance]] in ''[=RM3=]'', [[spoiler: has not yet gone AxeCrazy and killed everyone in Pasca. Ultimately an InvertedTrope, as Niata is a refugee from the world P. Kanonno has yet to destroy and tries very hard not to let in on this.]]
* VillainOverride: [[spoiler:Lazaris]] suffers this fate in [=RM3=] [[spoiler:when the Document of Jildia forcefully takes over her body in a last-ditch effort to stop the heroes. It's almost enough to push her into AlasPoorVillain status, given how hard she tried for the sake of Jildia, only for Jildia to hideously mutate her and strip her will]].
* VirtualPaperDoll: Armor is visible when worn.
* WellIntentionedExtremist:
** Widdershin and [[spoiler:Pasca Kanonno]] in the first game. Aurora is implied to have been one herself, but by the time the game begins she's a full-fledged villain.
** Lazaris in the third game [[spoiler:just wants her world (Jildia) to be born]], even though that involves destroying Luminasia. She even acknowledges that her wish is a selfish one, but justifies it [[spoiler:as Luminasia essentially denied Jildia the opportunity to be born as a world]].
* TheWorldTree: It's what ushers the Descender into existence.
