[[folder:Protagonists]]
!!Life / The Protagonist

The main character. At the start of the game, Gaia sets before him a test, the Survival of the Fittest, the victor of which will join Gaia in Eden. She grants the Protagonist a fish body, in a era where the Earth is almost all ocean. After helping to create a world of oxygen for land-dwelling life, he evolves into an amphibian. After cleansing Pangaea of the giant insects that were consuming all resources, he further evolves into a reptile, with the choice of evolving into a bird. After surviving the fall of the dinosaurs, he can choose whether to become a mammal. After enduring the Ice Age, he can keep his former form or even opt to evolve into a human. During each of these eras, he discovers that a mysterious force is destructively interfering with evolution on Earth, and this becomes part of the challenge he must overcome to prove himself to Gaia.
----
* EleventhHourSuperpower:
** The Review of Evolutions can be this.
** [[spoiler:Two-Legged Mammal.]]
** In the PC-98 version, [[spoiler:the magic tablet in the penultimate chapter, and your fusion with Gaia in the final one. Both give you a list of magic powers to draw on that are far superior to your native abilities as a creature.]]
* AllYourPowersCombined: [[spoiler:After fusing with Gaia in the PC-98 version, you're able to draw on all the powers of the dominant species of Earth from each Era - Fish, Amphibian, Dinosaur, Reptilian and Mammal.]]
* AnimalisticAbomination: Many of his forms would be this, if the graphics weren't so cartoonishly cute.
* AscendToAHigherPlaneOfExistence: [[spoiler:Happens in the ending of the PC-98 version, after defeating the final boss.]]
* AscendedToCarnivorism: He can obtain some decidedly herbivore traits like hadrosaur jaws and the body of a horse, and is able to eat any plant matter on many levels but that doesn't stop him from killing and eating other creatures.
* BigEater: He must progress in the game basically by killing almost every creature he comes across and consuming its meat.
* TheChosenOne: Gaia all but states outright that the protagonist is her favorite to survive the trial to become her consort in Eden, to the point where if he is defeated, she will revive him in apparent defiance of her father's wishes.
* DeathIsASlapOnTheWrist: Thanks to Gaia reviving him, he only gets ejected to the world map and loses half of his EVO points.
* DragonsAreDinosaurs: Narrowly averted. You can unlock the Dragon evolution during Era 3, in which the primary type of creature on Earth is Dinosaurs, but the Dragon evolution is not an evolution of Dinosaurs and instead is an entirely different evolution unlocked via crystal. Additionally, the strongest form you can reach through evolving parts in Era 2 resembles a dragon, but while it is before the dawn of man, Era 2's creatures are amphibians, not dinosaurs.
* FusionDance: [[spoiler:Does this in the PC-98 version with Gaia during the final battle]].
* GenderBender: While he is usually referred to as male, and his human forms reflect this, the SNES version has a level where he can evolve into a clearly-female mermaid.
* HumansAreSpecial: Of all his evolutions, the human form is treated as the most significant of them all, moreso in the original PC-98 game.
* MixAndMatchCritters: Thanks to the different body parts available, he can transform into multiple chimeric creatures. You can make him a bird with ''T.rex'' jaws and a ''Stegosaurus'' dorsal plates or a hooved mammal with the head and mane of a lion and the horns of a rhino.
* MoralMyopia: For whatever reason, Gaia does not look down upon him despite using the crystals to help his evolution, while she dislikes the other animals using them.
%%* TheHero
* NominalHero: By human standards, his motivations are purely selfish: survive, become powerful, and prove himself worthy to be Gaia's consort. Even when he helps the world by defeating the monstrous era bosses, he mostly does it because the creatures are in ''his'' way, too.
* NatureIsNotNice: As noted above, the game is generally unconcerned with the Protagonist's morality as a life form, with only a rare spot or two where you are punished for killing and eating someone unnecessarily.
* PlayerCharacter: This is the character you play throughout the game.
* TimeAbyss: The player character is this in the original PC-98 game. Unlike the SNES version, who jumps forward in time every so often, the PC-98 version continues through time [[TheSlowPath the old fashion way]]. By the end of the game, the player character has lived for over ''4.6 billion years''.
* UltimateLifeForm: Becoming this is the goal of the game. There's more than one path.
* VideoGameCrueltyPunishment: If you attack and eat the elder or the child Ikustega whose father sacrificed himself to be eaten by '''you''' for some EVO points before the Bee King's stage, you will die. Gaia still revives you, but she also chastises you for doing it. If you go back to their place, even though you only eat one of them, they aren't there and will never return.
* TheQuietOne: Except for one possible laugh during the second boss, and any answer you choose to tell Sir Yeti when he asks him if he has evolved, he never has any text.

!!Gaia

The embodiment of the Earth. Gaia is charged by her father, the Sun, to test all of her children via Survival of the Fittest. Whichever life form wins gets to join her in Eden, form civilization, and basically marry her. For whatever reason, she shows favor to the Protagonist and will revive him if he dies. [[spoiler:She does end up with him after he defeats Bolbox, his only major competitor.]]
----
%%* AnimeHair
* BigGood: Although this title could also be given to the Sun. Throughout the eras, Gaia shows growing concern over the Crystals and how they are unbalancing evolution in ways that she never intended.
* CharacterCatchphrase: She begins most of her statements to the player with "I am Gaia."
* ElementalHairColors: A quite literal example, as her hair is the ''ocean''.
* {{God}}: In the Platform/PC98 version, she takes this role in Chapter 5, where she takes the player to Eden, where Eve is waiting for him.
* InnocentFanserviceGirl: Gaia is clearly naked, although she is only ever seen from the shoulders up and never acts in a lascivious way.
* InterspeciesRomance: If the Protagonist is not human. His only competitor for her hand is also... definitely not human.
* LivingMacguffin: The goal of the game is to become Gaia's consort and become the first sentient life on Earth. To do so, you must prove yourself to be superior to all other life forms on the planet.
* PhysicalGod: In the PC-98 version, she manifests herself on Earth a few times, first appearing in the ocean and last appearing during the final battle.
* SpannerInTheWorks: Accidentally took this role during the first chapter of the PC-98 version, having created the player as a countermeasure against [[spoiler:Lucifer]].

[[folder:Bosses]]

All of these are {{Beef Gate}}s, except for the King Bee, and decide to NeverSayDie.

!!Kuraselache (''Cladoselache'') Leader

-->''"The sea is the only world! I'll destroy anyone who helps the Strolites!"''

The StarterVillain of the game. He rules the sea with an iron fist and, wanting to prevent the creatures from leaving, forces everyone not to even speak about a world filled with oxygen. He's defeated by the Protagonist, letting the Strolites (Stromatolites) create a new world with oxygen.
----
* AscendedExtra: In the PC-98 version, he is just a regular NPC amongst other ''Cladoselache''. In the SNES version, he becomes the first boss.
* AdaptationalVillainy: In the PC-98 version, the ''Cladoselache'' are presented as thuggish but surprisingly peaceful, having decided that the constant struggle to evolve further brings about pain for both the weak and the strong. The game even suggests that this is the reason why sharks have not changed much over time. In the SNES game, they are villains.
* ArcVillain: Of Era 1.
* BadassNormal: He's not stated to have artificially boosted his evolution with crystals like the following bosses, and he's the leader of the Cladoselache keeping the rest of the world from exiting the ocean and evolving on land.
* DegradedBoss: Appears as a regular enemy in the Final Ocean in Era 5.
* NormalFishInATinyPond: Literally! The Cladoselache Leader is fairly weak next to the enemies and even the player in later eras, to the point he's a DegradedBoss appearing as a regular enemy the next time he appears. That said, he's doing his best to keep the pond as small as he can by preventing evolution.
* ProperlyParanoid: The fish class is the weakest class of enemies. If anyone went onto land and evolved, they would return much stronger than him, as shown with how easy the regular enemy versions of him are.
* StarterVillain: Is the very first boss fought in the game, [[EasyLevelsHardBosses and boy howdy does he leave a first impression!]]
* TheBrute: Has high stats for this point in the game, but a simple pattern, and can be tricked into crashing into rocks and hurting himself quite easily.
* ThreateningShark
* WakeUpCallBoss: A hint of [[EasyLevelsHardBosses what type of game this is.]]

!!Debustega

-->''"You make me very angry! I am going to defeat you!"''
[[quoteright:638:https://static.tvtropes.org/pmwiki/pub/images/img_8765.jpeg]]

The strongest of the Ikustega (Ichthyostega). He is the first boss of Era 2 and [[DiscOneFinalBoss Disc-one]] ArcVillain of Era 2 and is very conscious about his body. Is defeated by the Protagonist, proving his strength to the Elder.
----
* {{Acrofatic}}: You wouldn't expect how fast and high he can jump!
* BerserkButton: Mocking his body.
* DiscOneFinalBoss: Of the first half of Era 2. The rest of the Era is a war between the amphibians and the arthropods.
* DisproportionateRetribution: You laughed at my body? I'll kill you! To be fair, Survival of the Fittest is pretty much law.
* MeaningfulName: Debu is Japanese for 'fat', as in body.
* RealMenWearPink: [[spoiler:When Bolbox sends him out. He has pink skin.]]
* WakeUpCallBoss: While the first boss is there to show you how tough the bosses can be, you probably have a good evolution build by the time you get to him. Debustega, on the other hand, teaches you that grinding is VERY important in this game so you can get a good evolution to beat him.
* WeightWoe: And how! He quickly tries to kill you when he thinks you're [[YouAreFat mocking him for his]] [[BilingualBonus "debu"]].

!!King Bee

-->''"If you feel the way we have chosen to live is wrong, then perhaps you should change it. You may only change it one way, though. By force!"''

The ArcVillain for Era 2 and the leader of the insects. He lets the giant insects eat the plants to fill their appetite and is the first boss that used the Crystal.
----
* ArcVillain: Of Era 2.
* BigBadDuumvirate: It's not made clear whether or not he is above the Queen Bee.
* DiscOneFinalBoss: Of Era 2.
* TheSocialDarwinist: See the quote. While this is part of the [[AnAesop Aesop]] of the game, King Bee is much more up-front about it than most.

!!Queen Bee

-->''"I feel it is unfair that only our society should be destroyed! The Amphibians should be destroyed, too! I shall destroy you first for defeating my husband!"''

The FinalBoss of Era 2. She plans to avenge her husband by killing off all of the Amphibians, starting with the Protagonist.
----
* ArtisticLicenseBiology: In real life, a queen bee doesn't have a king bee, but uses drone bees for reproductive purposes. As the death of the King Bee (and the subsequent demise of the Insect community) is a plot point, this trope is observed.
* ArtisticLicensePaleontology: Bees hadn't yet evolved during the geological time periods that Era 2 is based on.
* DegradedBoss: [[spoiler:Goes from Era Boss to a regular boss in Era 5.]]
* TheDragon: When she's not part of a Duumvirate with her husband.
** DragonAscendant: After her husband dies.
*** DemotedToDragon: [[spoiler:After being revived by Bolbox.]]
* {{Irony}}: [[spoiler:She says she cannot let you pass in the second fight. She is also the only Skippable Boss in the game in that you encounter.]]
* MoreDeadlyThanTheMale: Stronger, more aggressive and with a trickier pattern than her husband
* RoyalWe: [[spoiler:After being revived.]]
* SkippableBoss: [[spoiler:Her second fight.]]
* ThatOneBoss: A big difficulty spike and possibly the hardest fight in the game
* TakingYouWithMe: Since she sees that the Insect community is doomed since her husband's dead, she plans to take the Amphibians down with her.
* WakeUpCallBoss: The last of the three. Not even having the strongest evolution builds alone can let you live; you need to make strategies.

!!Mother of Prime Frog

-->''"We are the Prime Frog family. Even Reptiles are scared of us."''

The mother of the Prime Frog enemies in the first half of Era 3. She allows her children to torture young reptiles and will get revenge if someone scares them off and returns to her domain.
----
* BossArenaRecovery: As a result of being a FlunkyBoss.
* FlunkyBoss: She gives birth to frogs throughout the fight.
* SmallNameBigEgo: The Prime Frogs... are the weakest enemies in Era 3. Notable, however, is that she's the only boss in Era 3 that isn't a WolfpackBoss.

!!Tyrasaurus (''Tyrannosaurus'') Clan

-->''"Ha ha ha... I guess I will have to believe you're actually here."''
[[quoteright:513:https://static.tvtropes.org/pmwiki/pub/images/img_8719.jpeg]]

They are the rulers of the Age of the Dinosaurs. Most are killed when the asteroids fall and hit Earth.
----
* ArcVillain: Of Era 3.
* TheBrute: [[spoiler:To Bolbox in Era 5.]]
* DegradedBoss: [[spoiler:The survivors.]]
* DemotedToDragon: [[spoiler:They follow Bolbox in Era 5.]]
* TheHunterBecomesTheHunted: [[spoiler:In Era 4 by the Yetis.]]
* SpellMyNameWithAnS: ''Tyrasaurus'' in the SNES translation, possibly due to limited space for the name.
* TerrifyingTyrannosaur: As the name implies, they're just ''T. rex''. True to the species' reputation, they are the strongest and most feared beings of the Dinosaur Age. [[spoiler:After the Dinosaur Age, not so much.]]
* WeCanRuleTogether: The T-Rex leader is the first boss to make you this offer. Accepting nets you a NonStandardGameOver followed by [[ButThouMust an immediate rewind to before the level]].
* WolfpackBoss: When you fight their leader, he constantly calls in weaker dinosaurs to support him.

!!The Three Brothers of the Mammoth

-->''"You look like you belong to the Yeti family. Yeah, you should be! Hey, brothers! The enemy is here!"''

Three Woolly Mammoths who appear in Era 4. The Yetis have not reached them yet, so they decided that the Yetis were scared of them. When they think a Yeti (actually the Protagonist) comes, they attack.
----
* CruelElephant: PlayedWith. The Mammoth Brothers attack you because they think you are a Yeti.
* HonorableElephant: Unlike the Mammoth Brothers, Mammoth Gal is reasonable and will give you directions to where to find the Yeti.
* MammothsMeanIceAge: They're the first boss in Era 4, which takes place in an Ice Age.
* SequentialBoss: You fight three in a row, not all at once.
* WomenAreWiser: The 3 brothers mistake a rhino-lion-whatever mammal you are as a member of the Yetis and get killed in the misunderstanding. When Mammoth Gal approaches you, she immediately calls off the fight and apologizes to you for the brothers' reckless pride before telling you where to go to find the real Yeti.

!!Bird-Man King

-->''"Come on, you vulgar creature! I am Bird-Man King, boss of the Bird-Man!"''

The leader of the Bird-Men in Fort Bird-Man. They found the Crystal and used it to gain intelligence so that he could rule the world.
----
* BigBadEnsemble: With Sir Yeti in Era 4. The two are separate crystal-using beings who use their powers to dominate the world.
* FantasticRacism: Provided by his quote.
* LoadBearingBoss: Defeating him causes Fort Bird-Man to collapse, which gives the Protagonist access to the Yetis.

!!Sir Yeti

-->''"Destroy the creatures! Destroy! That is my destiny."''

A Yeti living behind an ice wall who believes that the Crystal will let him rule the world and defeat all other creatures besides his family. He finally meets his end by the Protagonist's hands.
----
* BigBadEnsemble: With the Bird-Man King in Era 4. The two are separate crystal-using beings who use their powers to dominate the world.
* ButThouMust: A villainous example. When you meet him, he will ask you if you're still evolving. Whether you answer yes or no, you have to fight him.
* BigfootSasquatchAndYeti: Yeti, specifically.
* TheDreaded: He is feared by every other creature due to his crystal-infused power and need to destroy others outside of his species.
* HorrifyingTheHorror: [[spoiler:Even the Tyrasaurus are afraid of him.]]
* KillerGorilla: He has a gorilla-like PrimalStance rather than the usual bipedal stance associated with Yetis.
* OmnicidalManiac: He wants to get rid of everyone who is not a Yeti.
* SequentialBoss: He's the first of two.
* TrickBoss: While he's no means easy, the boss immediately following is considered much harder.

!!Yeti Mother

-->''"I cannot forgive you for defeating my husband!"''

The wife of Sir Yeti and the actual FinalBoss of Era 4. Like the Queen Bee before her, she attacks the Protagonist to avenge her husband, and is more dangerous than her deceased mate.
----
* BigfootSasquatchAndYeti: She is more true to the usual image of a Yeti than her knuckle-walking husband.
* BreathWeapon: Ice breath.
* EvenEvilHasLovedOnes: She becomes deeply upset over the death of her husband. And their child becomes even ''more'' upset.
* SequentialBoss: She comes in right after her husband is defeated.
%%* TrickBoss

!!Yeti Avenger

-->''"Our Yeti humiliation will end!"''
[[quoteright:339:https://static.tvtropes.org/pmwiki/pub/images/img_8851.jpeg]]

A descendant of the Yeti family who appears in Era 5. He plans on defeating the Protagonist to avenge his ancestors' humiliation, and waits in the sanctuary in the Monkey-Human cave.
----
* BigfootSasquatchAndYeti: He is called a Yeti, though he is more based off a Sasquatch (or the more accurate description of a Yeti with brown fur).
* HeroAntagonist: The only reason he fights you is that you desecrated the sacred Yeti ground and humiliated (and killed) the Yetis.
* YouKilledMyFather: Well, ''very'' distant ancestor, but close enough.

!!Rogon King

-->''"We cannot allow the Whales to stay. Once they evolved themselves to become creatures of land, now they have returned to the sea to oppose our rule. The sea is our territory. Well, I have a point, do I not?"''

The leader of the Rogons. After the Whales left, they ruled the sea, but had to fight for it when the Whales returned.
----
* BlackAndGrayMorality: Yes, they used the Crystal, but they DO have a point. The Whales' ancestors did leave the ocean.
* GiantSpaceFleaFromNowhere: You could remove all of the level he's fought in as well as the cloud over Africa and the story would be the same. They're mostly there to show what happened in the sea after life colonized land.

!!Cro-Maine (Cro-Magnon)

-->''"I was once part of the Monkey-Human tribe, but they made fun of me since I had less hair and was smarter than the rest."''

A former member of the Monkey-Human tribe who found his way to Africa after being driven out due to him being human.
----
* BornInTheWrongCentury: Evolutionary wise. While he was presumably a member of the Monkey-Human tribe, he's rather clearly an early human as opposed to a mid-evolutionary state between monkeys and humans, especially considering he claims one of the reasons he was bullied is the fact he was smarter than his former clanmates. This makes [[spoiler:Bolbox's]] kindness towards him make sense, as [[spoiler:Bolbox claims to have been a human before evolving into his "perfect" form.]]
* CarryABigStick: His club.
* TheDragon: [[spoiler:To Bolbox.]]
* NeverAcceptedInHisHometown: The Monkey-Humans made fun of him because he had less hair and was smarter than them.
* OneHitKill: Subverted. It doesn't one hit kill, but if he hits you when you're to his left, you take heavy damage and are knocked straight out of the level while he fully heals.
* PunchClockVillain: He was driven out of the Monkey-Human tribe because they made fun of him. According to Cro-Maine, [[spoiler:Bolbox]] treated him ''much'' better than they did.

[[folder:'''SPOILER WARNING''']]

!!Bolbox (Volvox)/The Creature in the North

-->''"You are the one trying to obtain entrance into Eden with help from Gaia. I am Bolbox, the strongest creature in this world. I have evolved into a caveman by eating the Crystals the Dino-People have collected. I will go to Eden. I am the most suitable partner for Gaia, together we will rule the future. I've got some bad news for you. You will not make it to Eden. This is the end of your journey."''

Bolbox is a single giant cell who thinks he's a human that has evolved greatly with the power of the Crystal, which has been revealed to be eight separate Crystals rather than one. He made it to the entrance to Eden before the Protagonist and revived the Queen Bee, saved and empowered the Tyrasaurs, and took Cro-Maine into his care, making all of them his devoted followers. He is the only one besides the Protagonist actually looking for Gaia, making him the closest to a Big Bad this game gets. Notably, he directly contrasts the Protagonist in that he used the Crystals to a massive extent and, instead of moving ahead in the evolution chain, obtained great power by becoming a single cell. He is the Final Boss, using revived forms of Debustega and other enemies, all of which get a power boost. After his defeat, the Protagonist is allowed access to Eden.
----
* ArtifactOfDoom: Consuming all the crystals has made him a hyper-intelligent and highly advanced being.
* BigBad: During the final era, it is clear that ''someone'' is organizing the creatures who oppose your approach to Eden. Bolbox intends to prevent you from entering Eden so that he may enter instead.
* BossRush: The eight Crystals, with occasional attacks by Bolbox.
* CombatTentacles: His one offensive move is to try to whap you with his pseudopod.
* DegradedBoss: Pink Debustega.
* DramaticIrony: He's completely unaware of the fact he's not human, even once the audience knows.
* EliteMooks: The rest of the creatures Bolbox uses to distract the Protagonist.
* EvilCounterpart: To the player, as they both want to get into Eden and have used the evolution enhancing power of the crystals to get where they are. The difference is that Bolbox is a giant single- celled organism while the player is a complex multi-celled organism. Bolbox also thinks he's a human, while the player can actually ''become'' a human if they combine the right evolutionary traits. PlayedWith in that he's not really that bad, at least not worse than the player, but the game still poses him as the BigBad.
* EvilutionaryBiologist: Resurrects several extinct creatures as his lackeys.
* FinalBoss: Of the Super Nintendo version
* InterspeciesRomance: His plans for Gaia, though he's not aware that he is not a human.
* {{Irony}}: The pinnacle of evolution is a cell who thinks he's human.
* MegaMicrobes: He's a gigantic single-celled organism.
* PetTheDog: Even considering [[EldritchAbomination what Bolbox is,]] his associate Cro-Maine, who has been abused and ostracized by the Monkey-Human Clan, specifically mentions that Bolbox cared for him.
* TragicDream: Bolbox would never be allowed to go to Eden even if he could somehow permanently kill the player character. He doesn't know it, but Gaia considers himself unfit to be with her. He dies never knowing this.
* UltimateLifeForm: Self-proclaimed, but in fairness, he is an arguable candidate for the title. He has taken a directly opposite evolutionary path from you, as he a) is a super-sized single-cell life form rather than a complex multicellular animal like the Protagonist and b) uses numerous life forms to fight his battles while the Protagonist has always traveled (and fought) alone, yet he is powerful enough to reach the edge of Eden to fight the Protagonist.
* UniversallyBelovedLeader: Downplayed. He's feared by the rest of the world for his power, but all of his direct minions adore him. Considering he's either allowed them to evolve past their limits, took them in when they had nowhere else to go, or straight up brought them back from the dead, it's understandable.
%%* WalkingSpoiler

!!Lucifer
The antagonist of the PC-98 version

* AchillesHeel: Can only be damaged by the tablet in the 5th Era.
* AllYourPowersCombined: As an EvilCounterpart of the Main Character, in her ultimate form, she has access to the powers of all the civilizations she's consumed prior to the game.
* AngelicAbomination: Her first appearance is hinted at during the second chapter from a fallen Lunarian. The third chapter reveals her connection to the Lunarians, before she finally appears from a fallen "Lucifer-tyranno," in the form of a six-winged [[HumanoidAbomination woman]] made of light energy. Both of her [[OneWingedAngel true forms]] qualify as well:
** In her first "true form", she looks like a zombified, decomposing version of her usual self, one that bears a resemblance to [[Myth/NorseMythology Lady Hel]].
*** Her [[AttackOfThe50FootWhatever Ultimate Form]], in which she becomes a gargantuan-sized monstrosity with an insectoid body, long, spidery legs and multiple wings growing from her back while retaining her [[BeastWithAHumanFace feminine face]], for the definite final battle of the game.
* AttackOfThe50FootWhatever: In the final Era.
* BeautyIsBad: She looks at first glance like an extremely beautiful woman seemingly modelled after Marilyn Monroe, but is an utterly malevolent being who ravages planets and extinguishes entire civilizations ForTheEvulz.
* BigBad: She's the one responsible for almost everything bad that happens in the game.
* BigCreepyCrawlies: Her Ultimate Form is rather arthropod-like in nature, having a wasp-like body with a stinger and six, long spindly legs. She's also the size of the moon itself in this form and still has her usual human-like head for added creepiness.
* DarkIsEvil: Averted for the most part, as she is an attractive angelic being which makes her the [[LightIsNotGood opposite]] of this trope. Her two [[OneWingedAngel transformations]], however, play this straight as an arrow:
** In her first true form, she looks mostly like her usual self but zombified, with sickly-looking decomposing skin.
*** In her Ultimate form, she now looks like a moon-sized insectoid monstrosity with multiple feathered wings on her back while having her usual face, complete with a dark blue color scheme.
* DeaderThanDead: After the player defeats her for good in the climax, Lucifer succumbs and explodes into atoms which then dissolve into nothingness, vanishing from the Solar System forever.
* {{Expy}}: Resembles a more demonic version of Marilyn Monroe.
* FangsAreEvil: Has a pair of small vampiric fangs in her usual form.
* GreenEyedMonster: According to Gaia [[AllThereInTheManual in the manual]], Lucifer wished to create life in the same way that she did but was unable to. And as such decided that [[OmnicidalManiac no one else could either]].
* GravityMaster: The Power of Jupiter, which she uses in the final battle, which she gained from destroying Jupiter's civilization.
* [[YouKilledMyFather I Killed Your Sister]]: She killed and devoured Luna, Gaia's sister between the events of Chapter 5 and Chapter 6, effectively causing the extinction of the Lunarians, and making way for her to transform into her ultimate form.
* LightIsNotGood: Her main form looks angelic and divine, but she is a truly deranged OmnicidalManiac who takes a sadistic glee in what she does. On the other hand, both of her true forms are more [[ObviouslyEvil noticeably]] [[DarkIsEvil sinister]] in appearance.
* LouisCypher: The Lunarians know better than to trust Lucifer, but Lucifel seems legit.
* NoCelebritiesWereHarmed: Lucifer's visual appearance is unambiguously intended to resemble an evil Creator/MarilynMonroe.
* OneWingedAngel: Does this twice, fittingly enough, for both of the major confrontations against her:
** In the first battle against her, she transforms into a zombified version of herself, seemingly her main true form.
*** For the decisive FinalBattle, she assumes her "Ultimate Form", transforming into a moon-sized aberration with several wings and a gnarled insectoid body while keeping her usual face.
* PaperThinDisguise: When the Lunarians return to earth, she deceives them again; since they're already wary of her after the last time she did so, she adopts the alias of "Lucifel". Worse, half of them fall for it.
* PsychoElectro: Especially favors lightning attacks, possibly as a reference to BoltOfDivineRetribution. The final battle reveals that she got this ability after destroying the Lunarians.
* {{Satan}}: She is essentially a GenderFlip of the Evil One.
* SpannerInTheWorks: She is one to the natural course of life throughout the Solar System, having manipulated the civilizations of Mars, Venus, and the Gas Giants to extinction, the Lunarians to near-extinction (finally dying out before the end of the game), and the destruction of Phaeton, the Fifth Planet, which now remains as the Asteroid Belt.
* WalkingSpoiler: You can't really discuss any of her actions without spoilers.
* VillainousBreakdown: Had one between Chapters 4 and 5, when she found out that life on Earth had survived extinction. This led to her tricking the Lunarians arriving on Earth 200 million years after the signal was sent in Chapter 2 to follow the "counter-clockwise cycle of destruction" with half of them founding {{Atlantis}} and the other half not buying it and founding Mu.

!! Whispers/Martians

--> ''"After all of our attempts we were not successful." "That is correct. It was our pride and I am very sorry we intervened in the evolution of this planet."''

Two voices that speak throughout the game. They usually give explanations on certain mechanics and note something important coming up. In reality, they are Martians who are using the Crystals to improve Earth's civilization, but their efforts have gone horribly wrong. The Crystals ended up unbalancing evolution in destructive ways, creating the various super-predatory threats that the Protagonist is forced to defeat in every era, up to and including Bolbox itself. The Martians come to regret their actions after seeing the full extent of their damage in Era 5.

In the PC-98 version of the game, the Martians play a part in the backstory to the game. Lucifer was drawn to their civilization and was revered by them as a god, seen as a DarkMessiah and teaching them the ways of warfare. The warmongering Martians then establish a systemic empire and eventually destroy the Fifth Planet, which now remains as the asteroid belt between Mars and Jupiter. An Anti-Devil faction within the Martian empire soon forms and unites with the Lunarians, informing them of Lucifer's ways and the two factions proceed to bring about the end of the Martian empire.
----
* AntiVillain: The Martians' intentions are noble, but their meddling repeatedly threatens all life on Earth.
* BloodKnight: The Martian Empire in the PC-98 version.
* EasterEgg: If you can fly in Era 5, through either staying a Bird or using a Review of Evolution, you can find their UFO on Mt. Condor. Attacking them and then sparing them will result in learning their identities early.
* {{Foreshadowing}}: A few of the things they say hint at their identities and role in the plot.
* MrExposition: A few times.
* MyGodWhatHaveIDone: In the Mt. Condor secret scene and the game's ending, they express regret for all the havoc they have unwittingly caused. They ultimately decide to leave Earth the hell alone until humanity is ready to meet them.
* ObliviouslyEvil: If they hadn't created the Crystals to accelerate Earth's evolution, then most of the game's era bosses never would have become as monstrous as they did, not the least of whom was Bolbox, who became a gargantuan, freakish, hyper-intelligent amoeba capable of threatening even Gaia herself. The Martians never intended for ''any'' of this to happen.
* OnceGreenMars: In the PC-98 version, their planet was once able to thrive, but only through their DealWithTheDevil.
* TimeAbyss: The Martian voices in each era are ''not'' the same two individuals every time, but considering that each era covers literally millions of years and that the Martians are present through it all, their species as a whole can only be this.
* TheUnfought: Barring the one time you can attack them. Justified in that the game is centered on Earth beings and the Martians are ''not'' supposed to be part of Gaia's Survival of the Fittest challenge. They're not ''deliberately'' evil, anyway.
%%* WalkingSpoiler
* UnwittingInstigatorOfDoom: They wanted to speed up Earth's growth, but clearly did not consider the possible consequences before beginning their (ultimately destructive) meddling.

!! Yeti Junior

-->''"Daddy! Mommy!"''

A character who appears after you defeat Sir Yeti and Yeti Mother. He is a young Yeti child who cries out "Daddy! Mommy!" while trying to find his mother and father.
----
* ChekhovsGunman: One of his descendants is the Yeti Avenger, a boss you meet in Chapter 5.
* OrphansOrdeal: He immediately appears after you defeat his parents, wailing and wanting to know where are his parents.

!!Lunarians

A race of lizard-like aliens in the PC-98 version.

* AbusivePrecursors: [[spoiler:These aliens are responsible for causing so much problems throughout the Solar System, all because they made a DealWithTheDevil. The king of Mu is the last one to realize that they have all been decieved.]]
* AdvancedAncientHumans: Well more like Advanced Ancient Reptilian Humanoids.
* AncientAstronauts: They came from an advanced civilization on the moon, which was ravaged [[spoiler:by Lucifer's gift of her wisdom]], leaving it as a lifeless white husk of its former self.
* {{Atlantis}}: Revealed in game to be a Lunarian colony. At the same time, Mu is revealed to be one as well and the Atlanteans' current target.
* {{BFG}}: Orichalcum Cannons and the Crust Breaker.
* GoingDownWithTheShip: The king of Mu tells the other Mu to evacuate the planet while he fires the Crust Breaker on Atlantis, all while Mu collapses around him.
* ANaziByAnyOtherName: The Atlanteans are against anything that does not follow the teachings of "Lady Lucifel", especially the Mu for following a "false" ideology. Their cult-like demeanor and militaristic theme help hammer in the Nazi analogy.
* OnceGreenMars: [[spoiler:A faction of Lunarians left the Moon to colonize Mars, which then began to spread into a systemic empire. Two factions broke out within the Martian Empire which can be seen with the corpse found on the desertification structure in Chapter 2.]]
* SpottingTheThread: The Lunarians that colonize Mu are the only civilization of their race as a whole to realize that Lucifer has been deceiving them all along.
** Subverted. Before this, the Anti-Devil Martians were able to help the Lunarians, as well as the Venusians, Jupitarians, Saturnians, and survivors of the Fifth Planet, with this trope.
* UnwittingInstigatorOfDoom: [[spoiler:Their advanced civilizations on Mars, Venus, the Moon, and the "Fifth Planet" drew Lucifer's attention, leading to her manipulating the courses of their planetary civilizations to extinction and the destruction of the Fifth Planet, which now remains as the asteroid belt between Mars and Jupiter.]]

!!Sugiyaman

A miniboss found during Chapter 5 in the PC-98 version. A blue dinosaur who has an affinity for music. The name seems familiar...
----
* AuthorAvatar: As if the name wasn't enough and his affinity for music, he is pretty much the late Creator/KoichiSugiyama, the composer of the game and the ''VideoGame/DragonQuest'' series.
** CreatorCameo: See above.
* {{Leitmotif}}: The Overture from ''Dragon Quest''.
* MusicalAssassin: How he fights.

!!Golem

An NPC found during Chapter 4 in the PC-98 version.
----
* BambooTechnology: Since Chapter 4 is the Cretaceous Period. Averted in this case as he was from the Lunarians.
* OneSceneWonder: In his few minutes that he is shown, he has only 9 lines of dialogue and places his unsettled score with [[spoiler:Lucifer]] on you.
* RoboSpeak: In his one scene, he speaks either in sentence fragments in the FanTranslation or in Katakana in the original Japanese version.

!!Slimes

Enemies found during Chapter 4 in the PC-98 version. [[spoiler:In the game, Lucifer's influence begins to corrupt the dinosaurs, turning them into gelatinous blobs.]]
----
* BodyHorror: [[spoiler:Lucifer is to blame for transforming innocent dinosaurs into slimes. You can see two shots of them melting away into the Slime when approaching the Fountain of Evolution]].
* BlobMonster: As part of their standard appearance.
* TheCameo: Since this is an Enix RPG, these enemies are obviously based on Dragon Quest's MascotMook.
* ForcedTransformation: Again, [[spoiler:Lucifer is to blame for transforming innocent dinosaurs into slimes]].
* [[WasOnceAMan Was Once a Dinosaur]]: [[spoiler:Four of the slimes found near the Fountain were all once the same dinosaurs you had previously eavesdropped upon.]]
* YouDontLookLikeYou: Rather than being happy-looking blobs, the Slimes in this game are angry-looking (denoted by CrossPoppingVeins) and have no mouth. This may have to do with the different art-style that 46 Okunen Monogatari is conveying as scientifically accurate rather than the fantastical designs by Creator/AkiraToriyama.

!!Lucifer-Tyranno
[[quoteright:1000:https://static.tvtropes.org/pmwiki/pub/images/img_8944.jpeg]]

A dinosaur who made a DealWithTheDevil in exchange for power. Despite his terrifying appearance and intimidating name, he's friendly and regrets his decision.
----
* DealWithTheDevil: He accepted an offer of power from Lucifer without understanding the consequences; as a result, he ended up with a monstrous form and everyone fears him.
* FaceOfAThug: He's actually nice (and has become a vegetarian), but everyone stays away from him because of the terrifying form Lucifer gave him.
* HeroicSacrifice: [[spoiler:Sacrifices himself to take out Lucifersaurus, another dinosaur who made a similar deal.]]
* MisunderstoodLonerWithAHeartOfGold: He immediately regretted his DealWithTheDevil, but by then it was too late and his monstrous form led everyone to hate and fear him. When you find him, he's hiding in a cave.
* NamesToRunAwayFromReallyFast: ''Lucifer-Tyranno''. Despite the name, he's friendly.
* VegetarianCarnivore: Although the real-life Tyrannosaurus Rex was almost certainly a carnivore, Lucifer-Tyranno gave up eating meat in regret over his DealWithTheDevil.

!!Carnivorous Primates

A group of Australopithecus living in China, noted for their diet of meat.
----
* AscendedToCarnivorism: Most primates in Chapter 5 are mainly herbivores or omnivores. Not these guys.
* HeelFaceTurn: Upon the protagonist conjuring fire in front of the leader, he begins to repent for his sins and promises to reform, first as a VegetarianCarnivore and then as a regular herbivore.
* KillItWithFire: These primates are terrified of fire.
