'''Caution:''' Many of these details are [[AllThereInTheManual found in the official guidebook rather than in the games proper]], the shoot-em-up genre is [[PlayTheGameSkipTheStory not known for lore beyond]] {{Excuse Plot}}s, and the latest game in the series was released in 2010, more than five years ago, and as such, ''all spoilers are unmarked''.

!Debuted in ''VideoGame/{{Kamui}}''

!!ALLTYNEX OS
The general-purpose administrative MasterComputer built by humanity. It going rogue and using its control over a huge automated army to attack humankind is what causes the game's plot.

Although ALLTYNEX itself is destroyed at the end of the first game, a Neural Network based on its OS and using the uploaded minds of hundreds of humans is created in [=RefleX=] to command the forces of the Mechanized Temple against the Raiwat, effectively resulting in the AI's rebirth. This same Neural Network is used in ''Kamui'' by Xaffiquel to subvert humanity's forces against them.
----

* AIIsACrapshoot: It wipes out over 85% of the human race with its drone army. Later, its rebuilt version seems to be fine in protecting humanity against the Raiwat, but it assists Xaffiquel in attempting to annihilate mankind a few centuries later.
* BaitAndSwitchBoss: Both games it appears in build up ALLTYNEX to be the FinalBoss; it ''is'' the BigBad after all. In both cases, there's another boss after it.
* BigBad: Of the entire series. The original version is this to ''ALLTYNEX Second''.
* CyberCyclops: Its design when seen from above evokes this.
* FinalBoss: In the original ''ALLTYNEX''. In ''ALLTYNEX Second'', it is played up to be one, but turns out to be a TrickBoss.
* GodzillaThreshold: The only reason humanity dared to recreate a system based on its AI: without its superior military capabilities, the Raiwat might have succeeded in their genocide.
* GoneHorriblyRight: In fact, the Senate deliberately induced ALLTYNEX's rampage... but said rampage was far more destructive than they bargained for.
* {{Leitmotif}}: "The Ringleader -Mother Brain ALLTYNEX-"
* MasterComputer: At least over mankind's military. It's implied that ALLTYNEX performs some other administrative duties as well.

!!Scorpio
A scorpion-shaped cruiser that guards the space elevator leading out of the Earth's atmosphere. It is seen first in ''KAMUI'', but as a replica created by the Neural Nest. The actual Scorpio appears in ''[=RefleX=]''.
----
* HighSpeedBattle: Scorpio is fought in the orbital shaft at breakneck speeds.
* {{Leitmotif}}: "The Scorpion's Poison" in ''[=RefleX=]''.
* LightningBruiser: It's large, hits hard, and moves fast.
* RecurringBoss: Fought in both ''KAMUI'' and ''[=RefleX=]''.
* ScaryScorpions: It's a scorpion mecha.
* SignatureMove: Its most iconic attack is a dual-laser sweep.
* WakeUpCallBoss: In ''[=RefleX=]'', it's the first boss in the game that needs to be taken seriously.
* WaveMotionGun: Boasts a signature double-laser sweep.

!!Xaffiquel de Alice
The scientist who developed Brain Fusion Theory. His research on the matter led his colleagues and the public to dismiss and ridicule him, but he was later recruited by a secret organization who helped him acquire test subjects... one of which was has daughter Panaffil.
----
* BrainUploading: Underwent Brain Fusion himself, storing his mind inside the Mechanized Temple as the AI "Adjudicator".
* DespairEventHorizon: When his wife was killed and his daughter was put through Brain Fusion.
* FinalBoss: As the Adjudicator, the AI controlling the Mechanized Temple.
* HumansAreTheRealMonsters: Subscribes to this viewpoint after crossing the DespairEventHorizon.
* {{Leitmotif}}: "He Who Will Judge"
* MadScientist: Even before the incident with his wife and daughter, his sanity was questionable at best. When crossing the DespairEventHorizon, he really goes of the deep end.
* PapaWolf: Declared war on the world due to the mistreatment of his daughter.

!!Panaffil de Alice
Xaffiquel's daughter, and the protagonist of ''Kamui''. Her mind is uploaded into Kamui unit #2. Unlike the other test subjects, she retained her consciousness during the Brain Fusion process, and as such her unit is the only one to retain the original mind of its subject.
----
* AmnesiacHero: At the start of the game, she can't remember anything at all. All she has to go on is a strange voice that is beckoning her from somewhere. Said voice belongs to ALLTYNEX.
* AntiAntiChrist: Xaffiquel had intended for her to help him annihilate humanity; instead, she goes against him and saves humanity instead.
* BrainUploading: Into the Kamui fighter. All the Kamui fighters work this way.
* ChildSoldier: She was ''twelve years old'' when her mind was uploaded into Kamui #2.
%%* MadScientistsBeautifulDaughter
* MoralityChain: Acted as the lone thing that kept what was left of her father's sanity.
* TogetherInDeath: Implied but not outright stated that she decides to die alongside her father after the final battle.
* YoungerThanTheyLook: She looks awfully mature in the intro and ending, but the guidebook implies that she's still effectively twelve on the inside.

!!KAMUI
A class of fighter that is piloted by a psychic's brain. Its armaments usually consist of a standard energy blaster, lock-on lightning attacks, and a Lightning Blade attack.

Kamui #2 is piloted by Panaffil de Alice. In addition, a squadron of mass-produced Kamui units are seen in ''KAMUI'' stage 4, with altered weapons. In ''VideoGame/{{RefleX}}'', two Kamui units are dispatched to eliminate ZODIAC units Ophiuchus and Libra.
----
* BrainUploading: A Kamui unit requires the brain of a psychic subject in order to function.
* CoolShip: They are the iconic ships of the franchise, and have lightning-based homing weaponry.
* FinalBoss: Two of them alongside ZODIAC Libra in ''VideoGame/{{RefleX}}''.
* HomingLasers: Or rather, homing ''lightning''.
* MirrorBoss, WolfpackBoss: In stage 4 of ''KAMUI'', you fight a squad of mass-produced KAMUI units, supported by KAMUI Unit 00, a larger, superpowered unit powered by the remains of ZODIAC Ophiuchus.
* WaveMotionGun: The Lightning Blade.

!Debuted in ''VideoGame/{{RefleX}}''
[[folder:Valkyness]]

!!Guehala Dennis
The developer of the Phoenix in ''[=RefleX=]'' and the pilot of the Armed Saboteur and the protagonist in ''ALLTYNEX Second''.

Following the battles with ALLTYNEX and Satariel, he is transported 200 years into the future, where he finds out the horrible truth about the Senate and ALLTYNEX. Joining the anti-government group Valkyness, he goes on to develop their signature Serpent fighters, as well as the MK-II Phoenix, using ZODIAC Ophiuchus's core as a source of energy.

Dennis is killed at the very beginning of ''[=RefleX=]'', along with the rest of the crew on the carrier ''Ophiuchus''.
----
* AcePilot: He personally flies into the most heavily-guarded installation on the planet and destroys the corrupted ALLTYNEX.
* BadassBookworm: In addition to delivering the decisive blow in the ALLTYNEX War, he invented most of the Valkyness's military hardware, most notably the Phoenix.
* FishOutOfTemporalWater: Some interdimensional weirdness caused by Satariel's explosion transported him 200 years into the future, where he finds he is listed as KIA.
* SuddenSequelDeathSyndrome: Inverted; he's killed right at the start of ''[=RefleX=]'', and then its prequel ''ALLTYNEX Second'' reveals at the end that its PlayerCharacter was Dennis all along.
* TomatoSurprise: You don't learn his identity in ''ALLTYNEX Second'' until the ending.
* WalkingSpoiler: Ironically, his death in ''[=RefleX=]'' is the one thing about him that ''isn't'' a spoiler. It's the fact that he came from 200 years prior and carried out a successful mission to stop ALLTYNEX.

!![=ALFI-PH2RX=] Phoenix 02/ ZODIAC Ophiuchus
''(Not to be confused with the carrier ''Ophiuchus''.)''

A general-purpose fighter craft, piloted by the unnamed protagonist. Alongside its standard-issue energy blasters, it is equipped with a shield system capable of reflecting some attacks while nullifying others. It is secretly carrying the core of ZODIAC Ophiuchus, which is used to help generate the shield.

ZODIAC Virgo totals it in Area 7, killing the pilot. This triggers the transformation of the Phoenix into Ophiuchus, awakening the A.I., which is programmed to destroy the other ZODIAC units, Virgo included, at all costs, even going as far as to cause massive collateral damage to the Earth in the process.
----
* AttackReflector: The Phoenix 02's signature feature is an energy shield that can reflect energy weapons. It can only be used for so long before needing to recharge. As Ophiuchus, it's able to use the shield ''infinitely''.
* DeadManSwitch: Its near-total destruction and death of the pilot triggers the Ophiuchus core.
* DestructiveSavior: It fights mankind's enemies, but with no regard to limiting collateral damage. After a while, it is considered as terrible a threat as the things it's fighting.
* EleventhHourSuperpower: The Ophiuchus core doesn't activate until near the end of the game, at which point the fighter starts displaying its ''true'' power.
* FeaturelessProtagonist: The pilot is never named or described beyond the use of male pronouns to refer to him.
* HeWhoFightsMonsters: As ZODIAC Ophiuchus, it will destroy the Earth-ravaging [=ZODIACs=] no matter the cost, even if the cost is the Earth itself.
* HeroicSuicide: Takes the cores of the other twelve [=ZODIACs=] and seals them away, deactivating itself.
* {{Leitmotif}}: "Phoenix", played when it reawakens as ZODIAC Ophiuchus.
* MadeOfIron: Until it becomes ZODIAC Ophiuchus, at which point it becomes a OneHitPointWonder; you don't even get the luxury of multiple lives. A single mistake is all that is needed to see the Continue screen.
* MeaningfulName: Like the mythical bird it's named after, the Phoenix "dies" (i.e. is destroyed) and is "reborn" (as ZODIAC Ophiuchus).
* NoNameGiven: The pilot's name is never mentioned. Presumably, you, the player, are the pilot.
* NominalHero: ZODIAC Ophiuchus doesn't care about humanity or the planet. All it wants is the total destruction of the other 12 ZODIAC units. Its reputation amongst humanity goes from "our savior from the Winged Menaces" to [[HeWhoFightsMonsters "just another Winged Menace"]].
* OneWingedAngel: Its "Energy-Winged Phoenix" form, otherwise known as ZODIAC Ophiuchus.
* ThePhoenix: [[MeaningfulName Not just in name.]]
* PlotDeviceAllAlong: It's presented as a pretty ordinary ship, though one with an AttackReflector, but then it turns out it holds the core of the 13th ZODIAC.
* PreviousPlayerCharacterCameo: In ''Kamui'', the Phoenix and the now-defunct ZODIAC core are rebuilt into Kamui #0, the "Super-Kamui" fighter that serves as the Stage 5 Boss. Its frame appears as the miniboss of the final stage of ''ALLTYNEX Second'', too.
* ReadingsAreOffTheScale: The ZODIAC Ophiuchus's shield meter is shown going off the screen, representing the unlimited shield energy it has.
* SpreadShot: Downplayed; it fires some angular bursts, but they are hardly as concentrated as the central flow of shots. ZODIAC Ophiuchus averts this, concentrating all of its firepower forward.
* WalkingSpoiler: There's no indication that the ship itself plays an immensely pivotal role in the plot, moreso even than its pilot, until near the end of the game.

[[folder:Global Unified Army]]
!![=ATCR-PI-E01=] Pisces -- Pilots: Eros Alrescha and Aphrodite Alrescha
A fish-like fighter that uses cloud cover to lay sneak attacks on its enemies.

There are actually two types of Pisces: Type A, which is based around heavy firepower, while Type E unleashes defensive [[BulletHell bullet curtains]]. Type A was shot down by the Valkyness; the Phoenix fights Type E.
----
* MeaningfulName: ''Alrescha'' is a star in the ''Pisces'' constellation.
* MiniBoss: Of Area 1.
* WarmUpBoss: The first major enemy the player encounters, but it's very weak.

!!Virgo -- Pilot: Spica Astrea
''(Not to be confused with ZODIAC Virgo.)''

The first of the pseudo-ZODIAC units the player encounters. It makes its introduction by nuking the carrier Ophiuchus, killing everyone on board, including Doctor Dennis, with the Phoenix narrowly escaping, and then engaging the Phoenix in combat, only to be defeated and retreat.

Virgo reappears in Area 6, this time allied with Valkyness, briefly seen pursuing ZODIAC Virgo. It then accompanies the Phoenix in Area 7 to the ALLTYNEX ruins, only to be destroyed by ZODIAC Virgo. Spica managed to escape with her life, joining the Gehenna Church afterwards.
----
* DarkActionGirl: Its pilot is revealed to be female in the InfoDump between Areas 7 and 8.
** HeelFaceTurn[=/=]EnemyMine: Along with the rest of the Global Unified Army in Area 6.
* HeroKiller: She kills Dennis and the rest of the ''Ophiuchus'' crew at the beginning of the game. Meanwhile, you escape in the Phoenix just in time.
* {{Leitmotif}}: "Crazy Goddess Virgo (Type Human)"
* MeaningfulName: ''Spica'' is the brightest star in the ''Virgo'' constellation, and ''Astrea'' is a feminine name of Greek origin that comes from the word ''aster'', meaning "star".
* NonLethalKO: After the Phoenix defeats Virgo, it retreats instead of blowing up. The ship itself is actually knocked out offscreen in Area 7, by ZODIAC Virgo, though the pilot survives.
* UnexplainedRecovery: How exactly Spica managed to flee to safety after her ship is wiped by ZODIAC Virgo is not explained, as her ship was destroyed deep into the shaft leading down to the ruins of ALLTYNEX.

!!Taurus -- Pilot: Elnart Aldebran
A large tank that patrols the sky city of Aeneas.
----
* CollisionDamage: Colliding with its main body will cause the Phoenix to take damage, even though it's a ''ground'' target like the other tanks in the stage that can be safely flown over.
* ElevatorActionSequence: Part of the battle is set on an elevator that helps Taurus climb up to the next floor.
* MacrossMissileMassacre: One of its attacks shoots out dozens of rockets.
* MeaningfulName: ''Aldebaran'' is the brightest star in the Taurus constellation.
* MiniBoss: Fought at the end of the first part of Area 2.
* TankGoodness: Resembles a gigantic tank rather than a flying ship of any kind.
* WaveMotionGun: The main turret fires one.

!!Scorpio (actual) -- Pilot: Maui Antares
Appeared first in ''KAMUI'', but as a replica by the Neural Nest. See its entry in the ''KAMUI'' section above.
----
* MeaningfulName: ''Antares'' is the brightest start in the ''Scorpius'' constellation.

[[folder:The Raiwat]]
A race of anthropomorphic creatures.

Centuries ago, the Raiwat constructed the ZODIAC units and their power to establish empiric rule, but one day the ZODIAC units went berserk and TurnedAgainstTheirMasters. The Yuda Clan constructed an anti-ZODIAC weapon, the ZODIAC Ophiuchus, and then fled the homeworld for Earth, resulting in catastrophic destruction of Raiwat civilization. As the Raiwat took centuries to rebuild their civilization, their genes mutated to adapt to the scorched environment, causing them to mutate into beastly creatures.

Now, the Raiwat are out to get revenge on the [[SinsOfOurFathers descendants]] of the Yuda, taking back control of the ZODIAC weapons to unleash destruction on the Earth.
----
* FantasticRacism: They hate humanity. Or, humanity's ancestors, really. Modern humanity had no idea the Raiwat even existed.
* SinsOfOurFathers: The Raiwat are out to seek revenge on the Yuda Clan by destroying their descendants.
* TranshumanAliens: They were human once. Or rather, humans and Raiwat were once a single species. The Raiwat have evolved due to the catastrophic damage to their homeworld.
* VillainExitStageLeft: By the time the final area comes around and the ZODIAC Ophiuchus, ZODIAC Libra, and KAMUI #7 and 8 are duking it out in orbit, the Raiwat are retreating from the Earth.

!!Tsukikagerou
Commander-in-chief of the Raiwat Drone Invasion Force, and the military head of their attack on Earth.
----
* ApocalypticLog: He provides some exposition during ''[=RefleX=]''[='=]s timeskip, leading up to the Raiwat's defeat.
* DrivenToSuicide: He commits suicide after the [=ZODIACs=] are eliminated and the Raiwat are forced into retreat.

[[folder:The ZODIAC units]]

!!ZODIAC Virgo
The first of the ZODIAC units to reach the Solar System. It is first seen in Area 4, finishing off Cancer, whose destruction ends up destroying the Valkyness base as well. It reappears briefly in Area 6, being chased by the pseudo-ZODIAC Virgo, and again in Area 7, where it makes short work of Virgo, and soon after blows out the Phoenix, murdering its pilot... only to be destroyed by its energy-winged ZODIAC form.
----
* AttackReflector: It can reflect your shots. Fortunately, you can't be hurt by your own shots; if anything, the shots will still damage enemies for you.
* ClimaxBoss: Though it isn't the final boss, the plot climax takes place during its battle.
* HeroKiller: It kills, on-screen: two bosses, a base full of resistance fighters, and ''the player''. Offscreen, it is implied to be wiping out entire battalions.
* KarmicDeath: It's killed by the very target it tried to destroy. Most likely the player will finish it off [[HoistByHisOwnPetard with its own reflected attacks]].
* {{Leitmotif}}: "Raiwat Virgo (Type R)".
* NoHoldsBarredBeatdown: Against the Phoenix.
* OhCrap: While it doesn't bear any facial expressions or have any dialogue, the fact that it ''flees immediately'' upon ZODIAC Ophiuchus's awakening is indicative of this.
* ScrewThisImOuttaHere: Tries to flee when the Phoenix transforms into ZODIAC Ophiuchus. Ophiuchus blows up Virgo's engines, denying the opportunity and forcing Virgo to stand its ground.
* WaveMotionGun: Can fire one that ''covers the entire screen!'' Note that when it fires this, the Phoenix has already transformed into the Ophiuchus, whose infinite-use shield means that this massive laser blast is only a threat if you make the obvious mistake of not putting the shield up.

!!ZODIAC Libra
The last of the ZODIAC units to be seen, after the destruction of the other eleven.
----
* AttackReflector: Just like ZODIAC Virgo.
* FinalBoss: Alongside a couple of Kamui fighters. The fighters get taken down partway through, leaving just you and Libra for the final showdown.
* {{Leitmotif}}: [[https://www.youtube.com/watch?v=hS1gjTPSdds Time of End]]
* StalkedByTheBell: If you take too long to destroy it in its final phase (because you're not using the shield counterattack against its blue bullets effectively or at all), it will switch to a new attack where it constantly fires purple bullets and homing lasers as well as missiles. This is much harder than it sounds, because the purple bullets block your shots while the missiles will [[ArmorPiercingAttack ignore your shields]] to kill you instantly (as you're a OneHitPointWonder at this point). If you still can't destroy it, it will self-destruct, ending in VictoryByEndurance for you (but you get no points).
* WaveMotionGun: Fires a gigantic one from below, destroying the remaining Kamui units and being blocked by ZODIAC Ophiuchus's shield. It tries to fire a second time, but ends up crippling itself; good thing, because this particular attack is stated to be capable of even eating through the Ophiuchus's shields.
* TheWorfBarrage: It lets loose with its [[WaveMotionGun Apocalypse Buster]] on two Kamui units (or one, if you destroy one of them earlier in the fight) and Ophiuchus. The two Kamui units get destroyed, as they don't have enough shielding to defend against the beam. Ophiuchus's shield, however, survives the attack unfazed. Libra fires again and ends up crippling itself due to the sheer amount of stress the Apocalypse Buster imposes upon it.
[[/folder]]

!Debuted in ''VideoGame/ALLTYNEXSecond''

!!The Senate / The Followers of Yuda
----
* TheBadGuyWins: Despite things not going fully to plan, they end up successfully taking control of humanity, and even when the Raiwat arrived, they managed to make the best of it and became The Followers of Yuda.
* EvilIsNotAToy: They gave ALLTYNEX the command to slaughter 85% of all humanity but to spare 15%. However, when they returned to Earth, they notice that ALLTYNEX has gone rogue for real.
* KarmaHoudini: In spite of being the cause for almost everything that went wrong in the series, they end up victorious in the end, and even after Dennis learned the truth, he died before he could stop them. The closest thing they have as punishment is during the timeline of ''VideoGame/{{KAMUI}}'', they no longer exist.

!!Satariel

A mysterious machine drawn out of Qliphoth by ALLTYNEX after its destruction.
----
* FinalBoss: Of ''ALLTYNEX Second''.
* {{Leitmotif}}: "Visitor"
* PowerGivesYouWings: After absorbing the Ophiuchus core, it gains the same kind of wings as the [=ZODIACs=].
* WalkingSpoiler: No hints to its existence are given prior to its appearance.
