->''In a different dimension from this world, there exists another world where every thousand years a legendary tournament is held.''

''Magical Battle Arena'' is a 3D aerial [[FightingGame fighting]] [[DoujinSoft doujin game]] developed by fly-system and Area ZERO, featuring the {{Magical Girl}}s and female mages of [[MegaCrossover several different franchises]].

The story behind this game revolves around a tournament that takes place every millennium, one consisting of many great and powerful mages from different worlds, in order to maintain the cosmic balance of magic amongst [[TheMultiverse the multiverse]]. The many participants are summoned from the world they originated in against their will and sent into a different dimension where the tournament is being held. A mysterious voice tells each one of them that they will need to win the tournament if they wish to return to their home, and that should they win, they will be granted one wish. If you want a more in-depth (and spoiler-heavy) details of the game's [[ExcusePlot story]], [[Synopsis/MagicalBattleArena we have a page for that]].

Additionally, Area Zero released a game called ''Magical Battle Festa'' on PC/Steam, which is essentially Magical Battle Arena but with original characters instead of copyrighted ones.

!!This game provides examples of:
* AntiVillain: Nowel and Ruru, as the plot above shows.
* ArtificialHuman: Nowel and Ruru.
* AttackDrone: Sarara. ''[=StrikerS=]'' Nanoha also uses Blaster Bits.
* AwesomeButImpractical: Every character's DesperationAttack. All their {{Limit Break}}s can hit a large area and multiple opponents, but the Desperation Attack is a one-on-one attack that if dodged leaves you wide open and vulnerable. Although, if it hits, you are almost guaranteed to win.
* BadassBack: Lina's Desperation Attack.
* BarrierMaiden: The fate of the Telos.
* BareYourMidriff: Would anyone expect anything less from [[MsFanservice Naga]] [[{{Stripperiffic}} the]] [[ChainmailBikini White]] [[ShesGotLegs Serpent]]?
* {{BFS}}: Jet Zanber.
* BeamSpam: Blaster 3.
* BerserkButton: Vita's Desperation Attack involves her opponent accidentally shooting off her NiceHat.
* BigBad: Nowel.
* BleachedUnderpants: Kirara and Sarara.
* CastFromHitPoints: ''[=StrikerS=]'' Nanoha's Blaster System, naturally.
** [[spoiler:Literally with Lord of Nightmares Lina. Every time Lord of Nightmares attacks or flies, she loses HP. This is a reference to the original ''Slayers'' light novel, where every time the Lord of Nightmares attacks Phibrizo, its hold on Lina Inverse decreases, and eventually its possession of Lina's body ends.]]
* CastFromStamina: The SprintMeter doubles as a Mana Meter for your normal ranged attack. When Fate switches to her Sonic Form, not only does her speed increase, but her Sprint Meter's rate of consumption while dashing drastically decreases as well.
* ChargedAttack: ''Divine Buster'', ''Axel Shoot'', and some other attacks can either be fired instantly or charged for more damage. The characters with this ability can't move while charging, though. Other characters are restricted to fully charging before releasing them, but can move while doing so.
* CombatTentacles: Gadget Drone Type-1, though it crosses the line into creepy sexual tentacles with its [[DoesThisRemindYouOfAnything highly suggestive-looking]] melee special.
* ConservationOfNinjutsu: Averted in the stages with a lot of Gadget Drones, but applies during the five-clone MirrorMatch.
* DefeatMeansFriendship: In addition to the above plot, Sakura and Kukuri ally with one other after they fight.
* DittoFighter: Sakura, thanks to The Mirror which allows her to morph into other characters à la [[VideoGame/MortalKombat Shang Tsung]].
* TheDragon: Ruru.
* DropTheHammer: Vita.
* DualWielding: Fate from ''[=StrikerS=]''.
* ExcusePlot (The plot is mainly a justification on how and why various {{Magical Girl}}s from different worlds are beating each other up)
* ExpansionPack: ''Lyrical Pack''.
** UpdatedRerelease: ''Complete Form''.
* FinalBossNewDimension: Subverted when it's usually Ruru who is fought in the other dimension in Story Mode.
* FiveManBand: If you squint a little, you could think of the five default characters this way.
** [[TheHero The Heroine]] and TheLeader: Type-II -- Nanoha, the most straightforwardly heroic.
** TheLancer -- Fate, Nanoha's counterpart, and a little rougher around the edges than most.
** [[TheBigGuy The Big Girl]] -- Kirara, the most physical of the girls.
** [[TheSmartGuy The Smart Girl]] -- Sarara, counterpart to Kirara and her moves have the most technological look to them.
** TheChick -- Sakura, the girliest.
* {{Golem}}: Naga the White Serpent's Limit Break.
* GlassCannon: Hayate's got some of the best special offense in the game, capable of tearing out huge chunks of life from an enemy. The only problem is, she has to stand perfectly still and has to charge her moves before firing them.
** ''[=StrikerS=]'' Nanoha can become this, when she has her Blaster mode on she hits harder than nearly anyone, [[CastFromHitPoints the only problem is...]]
* GoldenSuperMode: The Lord of Nightmares possessing Lina makes her shine.
* GravitySucks: Kukuri's ''Mini Planet''.
* HarderThanHard: The aptly named Nightmare Mode
* HarmlessFreezing: Lina and Naga's ''Freeze Arrow'' spell.
* HoldTheLine: Some missions require you to survive until the countdown ends.
* HotBlooded: Kirara.
* HumongousMecha: [[spoiler: The Desperation Attack of the ''Magic Knight Rayearth'' girls.]]
* IBelieveICanFly: {{Flight}} is a requirement for any character to be included, due to the gameplay.
* AnIcePerson: Naga's ''Dynast Breath'' and Hayate's ''Atem des Eis''.
* ImprobablyFemaleCast: The only non-female character in the game is the Gadget Drone.
* JigglePhysics: Naga, although it was inevitable given that she's ''Slayer''[='=]s [[GagBoobs bustiest]] character.
* JokeCharacter: Gadget Drone Type-I.
* LethalJokeCharacter: Kukuri. No, seriously.
* LimitBreak: The {{Desperation Attack}}s.
* MagicalGirl: Oh, so many.
* MacrossMissileMassacre: Ruru's ranged special.
* MakeMeWannaShout: Naga's Desperation Attack. If you know Naga, you should have a pretty good idea what this is.
* MakingASplash: Umi's ''Aoi Tatsumaki''.
* ManaBurn: Kukuri's ''Long Voiced Cat'', which depletes a character's ChargeMeter.
* MassiveMultiplayerCrossover
* MegaCrossover: Justified that this is a fan-made game.
* MirrorMatch: In Stage 5, you fight five clones of yourself.
* MsFanservice: [[{{Stripperiffic}} Na]][[ChainmailBikini ga]], [[JigglePhysics Na]][[GagBoobs ga]], [[ShesGotLegs N]][[StatuesqueStunner a]][[RuleOfThree ga]]...
* NoblewomansLaugh: Naga, of course, and it's one of her {{Limit Break}}s.
* PaletteSwap: The Clones, and your opponents in Survival Mode.
* PantyFighter: {{Magical Girl}}s in skirts fighting in mid-air. {{Panty Shot}}s are inevitable.
* PillarOfLight: Nowel's Desperation Attack.
* PlayingWithFire: Lina's ''Fire Ball'' and ''Gaav Flare'', Sakura's ''Firey'', and Hikaru's ''Honou no Ya''.
* PowerCreepPowerSeep: Power-wise, Sakura from ''Cardcaptor'' could match the other magical girls in terms of power, but it's a little harder to imagine her being as durable as Nanoha or Lina, considering how she kinda has the durability of an ordinary elementary school student.
* PowerFist: Kirara.
* PurposelyOverpowered: [[PhysicalGod Appropriately]], [[LightNovel/{{Slayers}} The Lord]] [[NamesToRunAwayFromReallyFast of Nightmares]].
* ReallySevenHundredYearsOld: Nowel and Ruru.
* RedOniBlueOni: Kirara and Sarara respectively.
* {{Roboteching}}: ''Axel Shoot'' and ''Plasma Lancer'', amongst others.
* ShockAndAwe: Hikaru's ''Akai Inazuma''.
-->"[=BemBem=]! Mou ii yo, mou ii! Mou ii yo~!"
* SceneryPorn: The Cephiro stage added in v1.70+ is WAY too well done.
* SinisterScythe: Fate from the original series.
* SpamAttack: Nowell's Desperation Attack as well as Sakura and Kirara's melee special moves. The former uses The Fight, if you're wondering.
* SphereOfDestruction: A lot of attacks, but especially Dragon Slave.
* {{Stripperiffic}}: Who else could be more stripperiffic than [[OverlyLongGag Naga]]?
* ThisIsADrill: Ruru, from her drill pig-tails, to launching [[MacrossMissileMassacre a barrage of drill-missiles]], she is the embodiment of this trope.
* ThemeTwinNaming: Kirara and Sarara.
* ThereIsNoKillLikeOverkill: Hayate's Desperation Attack summons Nanoha and Fate and they use their ''Starlight Breaker'', ''Plasma Zamber Breaker'' and ''Ragnarök Breaker'' attacks at the same time at the enemy... In the second season of ''Magical Girl Lyrical Nanoha'', this attack combo was used to [[spoiler:stun the [[ArtifactOfDoom Book Of Darkness]], a being so powerful that ''entire armies couldn't defeat it'']].
* ThrowTheBookAtThem: Hayate.
* WaveMotionGun: Come on. We've got ''[=StrikerS=] Nanoha'' here, of all people! Her "normal" Super Move is the Blaster-3 Starlight Breaker (alias ''five simultaneous Starlight Breakers aimed at a single target from multiple directions'') with which she... er... ''officially adopted'' Vivio. It does even more damage than her Desperation Attack, and even if you manage to escape the beams the shockwave is so huge that in the smaller maps there is no way to avoid it, and in the bigger ones it will require a full bar of stamina to escape in time. In three word: ''[[WaveMotionGun Wave Motion]] [[BeamSpam Spam]]''.
* YouCantFightFate: Nowel's belief.
** ScrewDestiny: ...and your character's answer to this.
* YouGottaHaveBlueHair: Nowel's is sort of a shade of lavender, and Naga's is purple. Played straight with Umi Ryuuzaki.
* ZettaiRyouiki: A lot of them have this.
