E.V.O.: Search for Eden

"About 4.6 billion years ago, the "Sun" had nine smaller stars and named the third one "Gaia". The Sun: My dear Gaia! Please listen to me. From this time forward, every 1 billion years, you will have children called "Life". One of them will be able to help you to build a new era. Each child will must endure a difficult trial. You might think it's too severe, but it is necessary. The trial is a test of Nature: "The survival of the fittest". If he passes, I will allow him to be your partner and to enter Eden."

A very unusual and highly obscure Action RPG for the PC 98 and SNES, in which you play a creature which evolves in order to survive the dangerous prehistoric world and eventually to join Gaia, a personification of Earth, in Eden. However the evolutionary process has been disrupted, and it is slowly revealed that there is an overwhelming force behind this.

The game received little attention upon its release, but has since become a cult classic and a pioneer of the evolution gaming genre. It is noted for its unique gameplay system, sprawling world and its epic, eon-spanning scale.

It was developed by a small company called Almanic, under the publishing of Enix.

""Mysterious Time Stream evolves you.""
 * Alluring Anglerfish: You, with the Angler Horn evolution.
 * Ambidextrous Sprite
 * Ancient Astronauts: A throwaway line early on mentions some kind of alien interference in seeding the crystals..
 * Anime Hair: Gaia, and how. Not much because of the odd shape, but rather because it's the ocean itself. The rippling light underwater is used on her hair. You can take a look here. Oh, and extra points for them being blue.
 * Apocalypse Wow: Shown at the end of Chapter 3 when a huge swarm of meteors falls down to Earth on the dinosaurs, killing them and bringing the Apocalypse Class to Class 4. Even the baby dinosaurs aren't spared from the destruction.
 * Applied Phlebotinum: The crystals.
 * Bamboo Technology: The Monkey Humans and utilize this.
 * Batman Can Breathe in Space: If you've evolved into a bird, then there are two secret areas (one in World 3 and one in World 5) in which you can fly right up into space.
 * Big Bad:.
 * Blind Idiot Translation:

""We shall look into your future.""
 * Boring but Practical: The Angler Horn isn't used to attack, but it makes Level Grinding easier.
 * Boss Rush
 * Braggart Boss: Many of the bosses are like this, especially Debustega.
 * But Thou Must!:
 * Making it worse, the game also likes to show you just how much damage you did when you do what Thou Must. The game makes clear that you're repeatedly committing genocide against multiple other species to clear the road for your own evolution. While it's shown to be necessary in many instances, or else an act of self-defense, evolution is still an extremely unforgiving mistress.
 * Several times, you're given options to side with or otherwise concede to major bosses. The result of this is a short flash-forward of the effects this decision has on history. Afterwards? You're booted back to the map screen without a word of explanation, and re-visiting the boss' area initiates hostilities immediately. You get a peek at what would happen if the game let you, but nothing more.
 * Collision Damage: Of the near infuriating kind.
 * Colony Drop: How the Dinosaur Age chapter ends.
 * Crystal Spires and Togas: Fort Bird-Man has a bit of this aesthetic; flying Mayincatec castles built on crystal-powered technology. Even more so, the Rogons and.
 * Death Is a Slap on The Wrist: Dying in the game only results Gaia resurrecting you at the cost of half of your saved up EVO points. Not much of a penalty when you don't have very many saved up.
 * Degraded Boss: The Kuraselach Leader, boss of Chapter 1, reappears in Chapter 5 as a regular (but rare) enemy.
 * Easy Levels, Hard Bosses: A lot of the main areas are pathetically easy, but most of the bosses are excruciatingly difficult.
 * Everything's Better with Dinosaurs: . When you get a new body, you'll even find your previous fish form to be better than the base amphibian, and the same for each evolution afterwards. Though oddly, using a green crystal to devolve back into a fish proves to be a significant power-down compared to just swimming as an evolved, later life-form type.
 * Everything's Better with Penguins:
 * At the north pole.
 * Everything's Even Worse with Sharks: The Kuraselache and their King in the first epoch, with the King becoming a standard enemy in the fifth epoch.
 * Evolutionary Levels: A necessary concession to the game mechanics. There are some exceptions in that it's not a clean "leveling" and there are many Mutually Exclusive Powerups.
 * Feathered Fiend: The Bird-Men.
 * Fish People: The Rogons.
 * Flunky Boss: Mother Prime Frog spawns baby Prime Frogs to help her fight you. Killing them provides meat, which can be used to regain health during this battle.
 * Gaia's Lament: During the Age of Amphibians, much of the world has turned into a barren wasteland due to the insects' overeating of the plants. Fortunately, the world gets better.
 * Giant Space Flea From Nowhere: The Rogons. Most of the rest of the enemies have some kind of foreshadowing, even if the plot's a bit thin and unconnected, but the Rogons are both required and have nothing to do with anyone else.
 * Goal-Oriented Evolution: The object of the story, as well as the game's central basic mechanic (unless the player is more concerned with creating entertaining life forms than functional ones).
 * Goomba Stomp
 * Green Rocks: The crystals.
 * Hit Points
 * Hopeless Suitor:.
 * Hyper-Destructive Bouncing Ball: The Trilobites from Chapter 1 and the Nautiloids from Chapter 3 can morph their bodies into a round shape and bounce around to attack. If you happen to be close to the ground and one of them does this beneath you, they'll basically ricochet between you and the ground until you die.
 * In-Universe Game Clock
 * Infinity+1 Sword:.
 * Innocent Fanservice Girl: Gaia is naked.
 * Instant Death Radius: Cro-Maine can hit you from almost halfway across the screen when he swings his club. Not only does it do a lot of damage, it'll send you flying right out of the level, and you'll have to start all over again. Meaning that he will have full health again, but you won't unless you went and ate some T-Rex meat to recover.
 * Interspecies Romance: You and Gaia (especially if you're not ). also has an interest in Gaia, for a more extreme example. Consider that some proponents of the Gaia hypothesis think humanity is supposed to be the ecosystem's reproductive system.
 * Irony:
 * proclaims itself to be the pinnacle of evolution. When you finally see it, it turns out to be.
 * Leap of Faith: Jumping off the top of Mt. Brave is the only way to.
 * Leave Your Quest Test: will each offer you a choice to join them and abandon your quest to reach Eden. If you accept, you will see a cutscene of the possible outcome then get sent back to the world map.
 * Leave Your Quest Test: will each offer you a choice to join them and abandon your quest to reach Eden. If you accept, you will see a cutscene of the possible outcome then get sent back to the world map.

"Debustega: You make me very angry! I am going to defeat you!"
 * Lego Genetics: E.V.O. runs on this trope. Every time you add or remove a part, the change is done instantly. This can be exploitable in boss battles by changing one's neck from short to long or vice-versa whenever you get low on health, completely refilling your health. The neck is the cheapest part to change, but you can substitute any part and do the same thing.
 * A better tactic - and an even stranger example of this trope - was to grow a cheap horn, which would also refill your health. The horn would 'break' after attacking with it 3 times... and this would somehow count as an evolutionary change, which would refill your health again.
 * Admittedly, E.V.O. isn't exactly clear on whether or not it's supposed to represent real evolution. There's substantial hints that the whole process is being, at least in the case of certain enemies, and many creatures berate you for not evolving "the proper way".
 * Level Grinding: Until you get the necessary jaw/attack.
 * Magnet Hands: Tool-based creatures don't drop their weapon when hit.
 * Mama Bear: Prime Frog Mother gets angry at you for scaring off the children tormenting a reptile.
 * Mix-and-Match Critters: The player character can be one, especially as a mammal.
 * Mook Bouncer:
 * The annoying Pteranodons on Mt. Brave will attempt to grab you and drop you off the mountain during your ascent.
 * The Cro-Maine miniboss may count, since his attack will knock you out of the level.
 * Mother Earth: Gaia.
 * Mutually Exclusive Powerups:
 * Back-of-the-head mutations always have trade-offs.
 * The top fins in the Amphibian Age.
 * The bird path has worse armor and HP than the dinosaur, but maintains their high attack power, and flies.
 * The dinosaurs have the highest possible attack and defense, but lack special abilities. They also have the largest amount of possible forms.
 * Never Say "Die":
 * You don't kill anyone. You "defeat" them. Especially funny when the bosses declare that "I'm going to defeat you!".
 * Averted in other cases. "Kill only for survival and for food."
 * Ninja Pirate Zombie Robot: Comes naturally with the ability to mix and match the body parts of different animals. Tiger head with bull horns on a rhino's body, anyone?
 * One-Hit Polykill: If they're all in the same area of your strongest bite.
 * One-Winged Angel: The well-hidden.
 * Our Mermaids Are Different: The secret mermaid evolution seems to be a human head and arms on a fish body. And you attack by sneezing... or, depending on your interpretation of the animation, kissing.
 * Palette Swap: Later incarnations of bosses do this, but one changes its skin entirely.
 * Parabolic Power Curve: Some upgrade paths are a bit more unwieldly (e.g. humans may have trouble in the Boss Rush); and one path entirely loses.
 * Point of No Return: Normally contained only across eras, but the first world has a one-way path.
 * Restart At Level One: EVO points are lost on a new body.
 * Schizo-Tech: Early humans use stone-age Bamboo Technology, but certain crystal-powered species (Bird-Men, the Rogons, ) have access to Crystal Spires and Togas.
 * Schmuck Bait: Go ahead, try jumping onto dry land before you've beaten the first boss and evolved lungs.
 * Scratch Damage: Minimum of 1 point of damage regardless of defense.
 * Scripted Event
 * Secret Level: In Chapter 3,.
 * Self-Imposed Challenge: Beating the game as a dinosaur, mainly because the Ice Age is slippy-slidey for them, and unlike birds they can't get around that by flying.
 * Side View
 * Slippy-Slidey Ice World: The Ice Age chapter, naturally. Mammals don't slide on it, though.
 * Spell My Name with an "S": This occurs due to text constraints and regular letter mutation, e.g. dinichthys to zinichthy, stromatolite to strolite, ichthyostega to ikustega, brontosaurus to brosaurus, tyrannosaurs to tyrosaurs,.
 * Starfish Aliens:.
 * Tech Points: You acquire EVO Points and spend them as you wish to evolve body parts.
 * That Makes Me Feel Angry: The Ikustega boss does this after you laugh at him.


 * Unmoving Pattern: Gaia's hair, which resembles shimmering waves.
 * Video Game Cruelty Punishment: Eat the friendlies in Chapter 2, and you're dropped to 0 HP (unless you evolve immediately after chowing down). This does not occur if you have evolved so that one jump on each will kill them
 * Violently Protective Girlfriend:
 * The cause of That One Boss, the Yeti.
 * The Queen Bee also counts, as she's furious with you for defeating her husband.
 * Subverted by the female Mammoth, who doesn’t fight you and says her male conspecifics were idiots.
 * Voluntary Shapeshifting: The whole gimmick of the game.
 * What the Hell, Player?: Attack the friendlies after defeating the first Chapter 2 boss.
 * Wrap Around: In World 4, you're somehow able to travel down from Australia and end up at the North Pole.

Tropes related to the original PC-9801 game:
 * Big Freaking Gun : The Orihalcum cannons.
 * Boring but Practical: Throwing rocks at your opponents does a surprisingly high amount of damage.
 * Darker and Edgier: Or maybe it's the SNES version that is Lighter and Softer.
 * Evil Laugh: The Big Bad does it a few times but a noteworthy one is when it's done so, as.
 * Family-Unfriendly Death: Is seeing small dinosaurs being swallowed by carnivorous plants bad enough for you? How about seeing ?
 * Kaiju: One of the bad endings has you evolved into this.
 * Let's Play: A Japanese Let's Play of the original PC version can be viewed here with this.
 * Multiple Endings: The game has a couple of bad endings that are usually achieved by making "wrong" evolution choice. It's not too hard to figure how to trigger them. Some others are triggered by making wrong choices in the game.
 * One-Winged Angel: has one and it's quite ugly, . Taken at a whole new level at the end of the game where.
 * : In this game, we have, who for some reason bears some resemblance to Marilyn Monroe.
 * Stylistic Suck: The images for the bad endings are not as detailed as the one used for the story scenes in the game. Probably justified as those endings are Played for Laughs. Usually.
