The main character. He is informed about the test of Survival of the Fittest and reaching Eden at the beginning of the game by Gaia after evolving into a fish. After allowing a world of oxygen, he becomes an amphibian. After defeating the last of the giant insects, he is further evolved into a reptile. He can choose his evolutions into becoming a bird or mammal later on. While no one else seems to care about Gaia, he solves troubles caused by a Crystal that's messing with evolution.

  • Ultimate Life Form: Becoming this is the goal of the game.
  • Video Game Cruelty Punishment: 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 the their place, even though you only eat one of them, they aren't there and will never return.
  • The Voiceless: Except for one possible laugh during the second boss, he never has any text.


The embodiment of the Earth. Gaia is charged by her father, the Sun, to test all of her children with Survival of the Fittest. Whoever wins get to be with her, form civilization, and basically marry her. She shows favor to the Protagonist and will revive him if he dies. She does end up with him after he defeats Bolbox, his only major competitor.

  • Big Good: Although this title could also be given to the Sun.
  • Catch-Phrase: "I am Gaia."
  • God: She takes this role in Chapter 5 in the PC-98 version, where she takes the player to Eden, where Eve is waiting for him.
  • Innocent Fanservice Girl: Gaia is naked (although she is only seen from the shoulders up).
  • Interspecies Romance: If the Protagonist is not human. His only competitor... is definitely not human.
  • Living Macguffin: The goal of the game is to become Gaia's consort and create sentient life on Earth. To do so, you must prove yourself to be superior to all other life forms on the planet.
  • Physical God: She manifests herself on Earth a few times in the PC-98 version, first appearing in the ocean and last appearing during the final battle.
  • Spanner in the Works: Accidentally took this role during the first chapter of the PC-98 version, having created the player as a countermeasure against Lucifer.
  • You Gotta Have Blue Hair: It's the ocean. In the climax of the PC-98 version, her hair is green, yet the Symphonic Suite for said game still has it as blue.


All of these are Beef Gates, except for the King Bee, and decide to Never Say "Die".

Cladoselache/Kuraselache Leader

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

The Starter Villain 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 create a new world with oxygen.

  • Ascended Extra: In the PC-98 version, he is just a regular NPC amongst other cladoselache. In the SNES version, he becomes the first boss.
  • Arc Villain: Of Era 1.
  • Degraded Boss: Appears as a regular enemy in the Final Ocean in Era 5.
  • Properly Paranoid: 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 in how easy the enemy versions of him are.
  • Seldom-Seen Species: Cladoselache isn't common in fiction.


"You make me very angry! I am going to defeat you!"

The strongest of the Ikustega. He is the first boss 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!
  • Berserk Button: Mocking his body.
  • Disproportionate Retribution: You laughed at my body? I'll kill you! To be fair, Survival of the Fittest is pretty much law.
  • Meaningful Name: Debu is Japanese for 'fat', as in body.
  • Real Men Wear Pink: When Bolbox sends him out. He has pink skin.
  • Wake-Up Call Boss: 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.

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 Arc Villain 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.

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 Final Boss of Era 2. She plans to avenge her husband by killing off all of the Amphibians, starting with the Protagonist.

  • The Dark Chick: To Bolbox in Era 5.
  • Degraded Boss: Goes from Era Boss to a regular boss in Era 5.
  • Demoted to Dragon: After being revived by Bolbox.
  • The Dragon: If she's not part of a Duumvirate with her husband.
  • Dragon Ascendant: After her husband dies.
  • Irony: 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.
  • Royal "We": After being revived.
  • Skippable Boss: Her second fight.
  • Taking You with Me: Since she sees that the Insect community is going to be done for since her husband's dead, she plans to take the Amphibians down with her.
  • Wake-Up Call Boss: 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.

Tyrannosaurus/Tyrasaurus Clan

"Well, I guess I have to believe you're actually here."

They are the rulers of the Age of the Dinosaurs. Most are killed when the asteroids fall and hit Earth.

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 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.

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.

Sir Yeti

"Destroy the creatures! Destroy! That is my destiny."

A Yeti living behind an ice wall who belives 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.

  • Trick Boss: 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 Final Boss of Era 4. She fights the Protagonist to avenge her husband but is defeated.

Yeti Avenger

"Our Yeti humiliation will end!"

A descendant of the Yeti family who appears in Era 5. He plans on defeating the Protagonist to end the humiliation, waiting in the sanctuary in the Monkey-Human cave.

  • Hero Antagonist: The only reason he fights you is that you desecrated the sacred Yeti ground and humiliated (and killed) the Yetis.

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.


"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.

  • Carry a Big Stick: His club.
  • The Dragon: To Bolbox.
  • Never Accepted in His Hometown: The Monkey-Humans made fun of him because he had less hair and was smarter than them.
  • One-Hit Kill: 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.
  • Punch-Clock Villain: He was driven out of the Monkey-Human tribe because they made fun of him. According to Cro-Maine, Bolbox treated him much better than they did.


Bolbox/The Creature in the North and the Eight Crystals

"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, empowered and enlisted the Tyrasaurs, and cared for Cro-Maine, 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 certain enemies, all of which got a power boost. After his defeat, the Protagonist is allowed access to Eden.

  • Interspecies Romance: Plans to with Gaia, though he's not aware of it.
  • Irony: The pinnacle of evolution is a cell who thinks he's human.
  • Mega-Microbes: He's a gigantic single-celled organism.
  • Pet the Dog: Even considering 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.
  • Ultimate Life Form: Self-proclaimed, but he is a candidate for the title, albeit one who has taken a directly opposite evolutionary path from you (towards a super-sized single-cell lifeform).
  • Walking Spoiler


The antagonist of the PC-98 version

  • Expy: Resembles a more demonic version of Marilyn Monroe.
  • Deader Than Dead: After the player defeats her in the climax, Lucifer succumbs and explodes into atoms, vanishing from the Solar System forever.
  • Humanoid Abomination: 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 woman made of light energy.
  • Spanner in the Works: 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.
  • Walking Spoiler


"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. They are really Martians and were responsible for the plot, creating the Crystals to improve Earth's civilization. The Crystals ended up causing chaos and mutated the Insects, increased the knowledge of certain flying animals, powered up the Yetis, upgraded the Rogons, and mutated Bolbox. They start to regret their actions after seeing the full extent of their damage in Era 5, apologizing for what they did.

  • Easter Egg: 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.
  • The Heavy: If not for them creating the Crystals, then a crushing majority of the antagonists of the game would have never become as monstrous and evil as they were, whereas Bolbox would have never evolved into a gargantuan, freakish amoeba.
  • Mr. Exposition: A few times.
  • My God, What Have I Done?: Their attitude in the Mt. Condor secret scene and ending show this.
  • The Unfought: Barring the one time you can attack them. Justified in that the game is centered on Earth beings and are technically not in Gaia's power. They're not evil, anyway.
  • Well-Intentioned Extremist: They wanted to speed up Earth's growth. They ended up creating massive chaos, culminating in the monstrous evolutions of Bolbox.

    Other (Super Nintendo) 

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.

  • Chekhov's Gunman: One of his descendants is the Yeti Avenger, a boss you meet in Chapter 5.
  • Orphan's Ordeal: He immediately appears after you defeat his parents, wailing and wanting to know where are his parents.

    Other (PC-98) 


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

  • Advanced Ancient Humans: Well more like Advanced Ancient Reptilian Humanoids.
  • Ancient Astronauts: They came from an advanced civilization on the moon, which was ravaged 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.
  • Unwitting Instigator of Doom: 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.


A miniboss found during Chapter 5 in the PC-98 version. A blue dinosaur who has an affinity for music. The name seems familiar...

  • Author Avatar: As if the name wasn't enough and his affinity for music, he is pretty much Koichi Sugiyama, the composer of the game and the Dragon Quest series.


An NPC found during Chapter 4 in the PC-98 version.

  • Bamboo Technology: Since Chapter 4 is the Cretaceous Period. Averted in this case as he was from the Lunarians.
  • One-Scene Wonder: In his few minutes that he is shown, he has only 9 lines of dialogue and places his unsettled score with Lucifer on you.


Enemies found during Chapter 4 in the PC-98 version. In the game, Lucifer's influence begins to corrupt the dinosaurs, turning them into gelatinous blobs.

  • Baleful Polymorph: Again, Lucifer is to blame for transforming innocent dinosaurs into slimes.
  • The Cameo: Since this is an Enix RPG, these enemies are obviously based on Dragon Quest's Mascot Mook.
  • You Don't Look Like You: Rather than being happy-looking blobs, the Slimes in this game are angry-looking (denoted by a Vein Pulse) 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 Akira Toriyama.
