[[caption-width-right:272:Monsters Rule!]]

The {{anime|OfTheGame}} of the [[VideoGame/MonsterRancher game of the same name]]. The plot of the series followed the adventures of Genki Sakura, a very hyperactive boy who wins a beta disk of "Monster 200X" (which has the same properties of the real MR game) in a video game tournament. No sooner does Genki start it, than he is transported inside the game, finding a real world of monsters inside. It is currently in turmoil due to an evil monster named Moo, who turns monsters evil and rules the land with an iron fist.

Genki joins up with a girl named Holly and her monster Suezo, who are on a quest to find and unlock the monster, Phoenix, which is the only known creature that can stop Moo. Genki gains his own monster, Mocchi, at the start of the series. Soon, the group are joined by Golem, Tiger, and Hare, in their uphill battle against Moo and his forces.

The PostScriptSeason third season, which featured Durahan (who was an EliteMook in the second season) as the main big bad, takes place a year later and has the group trying to save Holly's father's soul, which is trapped in a dark mystery disk along with Moo after his defeat. However, most of the {{MacGuffin}}s the crew had before are now prizes in a tournament, forcing the crew to enter it to accomplish their goal. All the while, they continue to dodge attacks from Durahan and his baddies.

The show managed to run for three seasons, two of which aired stateside on syndication, Fox Kids and ABC Family respectively. The third never aired on TV in the U.S., but was dubbed, and is available [[http://www.hulu.com/monster-rancher online]] to watch. The show was also quite different from the other mon shows at the time (Pokémon, Digimon) in that the human protagonists were not afraid to battle alongside the monsters. While not as famous as its fellow mon series, the anime managed to at least gain a cult following. Many even regard it as a hidden gem among anime for its focus on character development and well done story pacing.

After 14 years, the series [[http://www.animenewsnetwork.com/news/2013-05-02/discotek-media-adds-monster-rancher-tv-anime-series got a complete English and Japanese box set release]] thanks to Creator/DiscotekMedia.

----
!!This anime provides example of:

* TheAbridgedSeries: Right [[http://www.youtube.com/user/Apterous964 here]].
* AbandonedLaboratory: The Searchers come across these a couple of times. Then the Baddies show up and unintentionally make things worse.
* AchillesInHisTent: In "Underground Adventure", Hare convinces the others it'd be faster to go through a cave than cross ''over'' the mountains. When they get lost, Tiger accuses him of ''intentionally'' leading them astray, and Hare promptly quits and storms off. The others get ambushed by [[MasterOfIllusion Joker]], and are saved when he returns. (However, Hare almost leaves ''again'' after finding the group, mistaking their reactions to the illusion as [[JustFineWithoutYou them having a great time without him]], and only realizes the truth upon seeing Joker.)
* ActionGirl: Holly is a downplayed version. Most of the time, she hangs back and lets the others fight... but if she has reason to, she ''will'' fight. Pixie is a straighter example after her HeelFaceTurn.
* AdaptationPersonalityChange: Colt, the assistant from ''Monster Rancher 2'', appears as an explorer in one episode. Since her game personality was nearly identical to Holly's, the anime made her a snarky, short-tempered explorer.
* AdvancedAncientAcropolis: The gang finds one kept orderly by Hengers and a Techno-Dragon.
* AfterTheEnd [=/=] AndManGrewProud: Turns out to be the backstory of the Moster Rancher world. The Pangaeaian civilization was incredibly advanced to the point that they thought they "were like gods". Then disaster struck, chaos and war broke out, and Moo nearly destroyed ''everything''.
* AllJustADream: Subverted, as Genki thinks this at the beginning of the eighth episode, but it turns out that it being a dream was itself a dream.
* AloofBigBrother: Deconstructed. Tiger was one of these with Gray Wolf in a misguided attempt to get him to toughen up. Instead, Gray Wolf became resentful and developed an inferiority complex.
* AlternativeForeignThemeSong: The Japanese theme song is different from the English one.
* AmusementParkOfDoom: Heroic example; the Searchers use an amusement park to their advantage against the baddies.
* TheAmazon: Our heroes have trouble traveling such a land for several episodes.
* AnyoneCanDie: Many characters die throughout the show, the main characters have almost died more than once, and in the second season finale [[spoiler:the five main monsters sacrifice themselves to become the Phoenix]].
* ApocalypseHow: Planetary/Societal Disruption, perhaps Planetary/Societal Collapse. Humanity once had an extremely advanced civilization [[spoiler: that eventually created monsters, stored in CD-[=ROMs=]/mystery disks]]. The monsters were first household pets, then anything that would make life easier, then warriors to fight what became known as the Last War which lasted centuries. Cue the war going too far, [[spoiler: ending up in the creation of Moo and in turn the Phoenix when Moo went wild, and what it took to destroy Moo meant destroying virtually everything.]] Enough humans were left to rebuild civilization, but ''far'' less advanced than it had been before.
* ArtisticLicenseHistory: Homo sapiens not only being around when Pangaea was still connected, but being around so long they can develop a [[AdvancedAncientHumans high-tech civilization]]. Justified that the events are happening in a video game or alternative universe.
* BackForTheFinale: Pixie, Big Blue, Monol, and the Pirate Dragons return for the final battle. Many other named characters are present fighting Moo elsewhere.
* BackstoryHorror: The backstory has humans who grew proud and destructive, creating Monsters for anything that would suit their wants. Eventually they created Moo in an attempt to end the last war, which ended up nearly destroying the entire planet until they created the Phoenix to stop him--and what it took to defeat Moo involved destroying virtually everything. Enough humans were left to rebuild civilization, but far less advanced than it had been before.
* BattleInTheCenterOfTheMind: Episode 73 had the Searchers fight Moo's evil soul this way.
* BigDamPlot: Used in "The Courageous Seven" as Evil Hares destroy a dam protecting a town, and the Searchers have to quickly build a new one.
* BigNo: Holly upon learning the truth about her father.
* BittersweetEnding: The third season was a PostScriptSeason, so if one goes on just by the originally planned second season finale, then this show's ending is even more bittersweet than that of TengenToppaGurrenLagann.
** To elaborate: [[spoiler: Mocchi, Suezo, Golem, Tiger and Hare all sacrifice themselves to become the Phoenix and fight Moo. Moo, though insane at this point, retains enough intelligence to remember the Phoenix and realizes they're destined to battle eternally, so he decides to destroy the Phoenix as well as himself-effectively killing Holly's father and the Monsters that make up the Phoenix. The resulting explosion knocks Genki off a Dragon's back and he seemingly falls to his death right in front of Holly... but is actually transported back to his world, with no way of letting Holly know that he's alright or finding out how the battle ended. However, he's comforted by a vision of all of his friends, who encourage him to move on with his normal life]].
** After all of that, the third season's quick StatusQuoIsGod followed by a TournamentArc left those who actually got to see it... underwhelmed.
* BlandNameProduct: [[{{Irony}} Mecto]]?
* BodyDouble: Attempted during "Magic Stone Mayhem" with [[spoiler: Genki and Holly switching clothes]].
* {{Bowdlerise}}: Several things were edited out of the dub; for instance, Hare defeating Tiger of the Wind using {{Fartillery}} was removed, and the fact he bought the others ''drinks'' along with dinner was left out (along with a drunk Tiger getting very ''buddy-buddy'' with Hare).
** Blood was edited out, along with moments deemed 'too violent'.
** During Captain Horn's introduction, he tries to kiss Holly. Holly blocks with Suezo, causing an accidental lip lock and LoveBubbles. Again, this didn't make it into the dub.
** When Joker snares most of the heroes in illusions, Suezo's hallucination is never shown (he [[HaremSeeker sees a bunch of female monsters]]). His reaction to the illusion breaking was also poorly edited.
** The second season was a bit better about this, letting Tiger bodyslam Lilim, for instance.
** For all the editing the dub did, it kept much of the DarkerAndEdgier stuff in, such as [[spoiler: Gray Wolf's death and Naga's suicide]].
** Moo chopping off Pixie's wings was edited out, along with any onscreen instance of him shocking her.
** In the third season, a shot of Poison's lower back is edited out.
* BreakTheHaughty: Tiger is humiliated by Captain Dino and Hare, the former in Tiger's debut episode and the latter in Hare's debut episode. He pays them both back for it.
* BreatherEpisode: "Holly's Happy Birthday" was entirely about the gang celebrating Holly's fifteenth birthday, without any battles.
* BroughtDownToNormal: Mocchi and Tiger end up losing most of their powers in the third season due to being turned into Mystery Disks. Thus have to relearn most of them. Tiger gets particularly frustrated about this, having taken so much pride in his fighting ability before -- and Suezo and Hare's teasing doesn't help.
-->'''Tiger:''' We don't need his help. I can handle all the fighting by myself.
-->'''Suezo:''' One blizzard, hold the ice.
* CainAndAbel: Tiger and Gray Wolf.
* CallBack: Tiger references Hare's plans and tricks from previous episodes. It adds to the sense of how vitriolically close they are.
* CanonImmigrant: Several ideas from this show were adapted into later games, such as the Phoenix being highly important, and Moo being a BigBad.
* CessationOfExistence: Becoming a Lost Disk and Monsters fusing together are portrayed as this.
* ChekhovsSkill: Mocchi's Cherry Blossom Blizzard failed to hit Pixie in episode 10 when she countered with a flame shield. When he tried the attack in episode 11 and it succeeded, it was so powerful it knocked her into some ruins.
* CherryBlossoms: Mocchi's signature attack is the Cherry Blossom Blizzard, and they become a symbol of the young monster. [[spoiler: The death symbolism comes into play during the second season finale, and the rebirth aspect comes in with the third season opener.]]
* TheChessmaster: Lilim and Durahan.
* ContinuityCameo: Colt, the assistant from ''Monster Rancher 2'', appears as an explorer in one episode.
* CrossCounter: Done between Mocchi and Most to end their fight in season 3. As Most was a more experienced fighter he kept standing, while Mocchi went down.
* DarkLordOnLifeSupport: After being weakened by the sun, Moo is in bad shape and is kept alive via life support while he waits for the Magic Stone as a cure.
* DarkerAndEdgier: The first and second seasons were more serious than the third.
* DefeatMeansFriendship: A very frequent theme.
* DelayingAction: After freeing Pixie's slaves, our heroes decide to stay behind and fight to buy time to escape. [[spoiler: Subverted, as one slave gets captured and used as a hostage, forcing the Searchers to surrender.]]
* DeployableCover: Some monster attacks can be used to counteract another. For example, Pixie blocking Mocchi's Cherry Blossom Blizzard with a wall of fire.
* DeusExitMachina: A few episodes see one or two of the Searchers get separated from the others; this happens to Genki the most often.
* DidYouJustFlipOffCthulhu: The end of episode 46 has the Searchers trying this to keep Moo from finding the Phoenix.
* DisguisedInDrag: In "Magic Stone Mayhem", Hare devises a plan to sneak Holly and the Stone safely away from their enemies, by having Genki and Holly swap outfits and then have Genki run interference while Holly slips quietly away with Tiger. Unfortunately, Lillim was DangerouslyGenreSavvy enough to see through it.
* DistressedDamsel: Holly for two episodes. It's played very well, though.
* DoesNotLikeShoes: Pixie. Genki claims this in episode 2, but it was more due having a little disagreement with Holly. He ends up getting some later.
* DoomedHometown: Holly's, which prompts her search for the Phoenix.
* TheDreaded: Tiger of the Wind, as well as Moo.
* DreadfulMusician: Mocchi in episode 58, and Suezo and Horn in episode 62. Their terrible, obnoxiously loud singing is PlayedForLaughs.
* DressingAsTheEnemy: When the Searchers are captured by some tree-like monsters, Mocchi attempts to sneak in by fashioning a disguise out of a tree. Despite using a yellow leaf as a Baddie emblem, Mocchi manages to get pass the gate. Alas, the bad guys catch on - which forces Genki to alert his friend.
* DrivenToSuicide: [[spoiler:Naga]].
* DuelBoss: Gray Wolf insists Tiger fight him one on one.
* EarnYourHappyEnding: Even if it's bittersweet, the Searchers had to earn it.
* EmergencyTransformation: Near the end of the second season, [[spoiler: Big Blue gives up his life to fuse with a fatally wounded Pixie, turning her into the hybrid Granity]].
* EstablishingCharacterMoment: Golem's is to straighten a flower Genki had trod upon and shelter it from wind.
* EstablishingSeriesMoment: In episode 1, Genki has just met Mocchi when the latter is threatened by the Black Dino Squad. What's Genki do when their leader threatens to make the young monster a slave? Kick the Black Dino in the face.
* ExpositoryThemeTune: The English dub. "Monsters rule!"
* EvenEvilHasLovedOnes: The Seed Sisters care for each other, at least.
* EvilCounterpart: Big Blue to Golem [[spoiler: at first]], Gray Wolf to Tiger, the Evil Hares to Hare, and the Knight Mocchi to Mocchi. Of note are the Knight Moochi, which Genki states he may be hesitant to fight because of the resemblance to his friend. [[spoiler: Lilim is one to Pixie as well]].
* EvilerThanThou: Lilim to Captain Weed, prompting a VillainousRescue as Lilim goes to kill the heroes.
* EyeScream: In his fight with Tiger, Gray Wolf whips his eyes with his tail, blinding him. In the uncut version there's blood.
* FantasyKeepsake: When Genki gets back to the real world, he's wearing the shoes that he was given earlier.
* FakingTheDead: PlayedForDrama in "Tiger Meets His Match", when the Searchers see what they think is [[spoiler: Tiger]]'s Lost Disk. It turns out to be [[spoiler: a hapless Evil Hare {{Mook}} who tried reminding Jagged Hound of why he was working with them in the first place]].
* {{Fartillery}}: Hare's Gas attack, which is ''much'' more potent than in the game, knocking out an entire stadium of people.
* FastballSpecial: Golem frequently threw Suezo into the air so he could get a better view of their surroundings, but didn't always catch him on the way down; and so, the entire fastball sequence became a RunningGag. The more traditional version also appeared a few times.
* FindTheCure: In "Run, Tiger, Run!", Tiger has to find Natsume Berries to cure Holly who has been attacked by Black Worm poison (see Taking The Bullet). Captain Black Worm follows and ambushes Tiger.
* FlatWorld: Discussed in "The Iron Bird". Upon reaching Haven's Canyon, Hare states that it's bottomless and the edge of the continent. Tiger (of all people) thinks it's nonsense, which Genki backs him up on.
* {{Foreshadowing}}: Throughout the first two seasons, it's heavily implied that [[spoiler:Genki is part of the Phoenix]] -- and Holly comes to the same conclusion during the penultimate episode "Tears". [[spoiler:Turned out to be {{Fauxshadow}}ing -- while Genki plays a key role in the Phoenix's revival, he's actually one of the '''only''' members who '''doesn't''' carry part of the Phoenix's soul.]]
** It is played straight in the sense that [[spoiler: Genki is connected to everyone who's part of the Phoenix, and he was the one who unlocked Mocchi. Without Genki, the Phoenix couldn't be revived]].
* ForeverWar: The conflict that resulted in the destruction of Ancients. It eventually degenerates into a HopelessWar [[spoiler: when Moo goes rogue]].
* FrothyMugsOfWater: The English dub has pirate Captain Horn coming to town to raid a supply of... chocolate milkshakes.
* GettingCrapPastTheRadar: The Pixie race is this. They are [[OneGenderRace all female]], wear {{Stripperific}} FurBikini, are often very flirtatious, and are also the most human looking of the monsters. Then you remember the history of monsters and that they were created as "Entertainment" for humans. With all that mentioned above, you start to wonder what kind of "[[SexSlave entertainment]]" the Pixies were created for. It also doesn't help they look a lot like a Succubus.
* AGodAmI: The ancient people of Pangea built a highly advanced civilization, creating Monsters to serve and fight for them. According to Monol, the people were as gods.
* GuestStarPartyMember: After turning good, Pixie and Big Blue show up sporadically to help the Searchers.
* HairRaisingHare: The Evil Hares.
* HeelFaceTurn: [[spoiler:Pixie]] and in the post script season [[spoiler: the entire big bad 4]].
** Tiger and Hare could both qualify, seeing as both had been thieves or con-artists.
* HeroicBSOD: Golem has one during his introduction in "Guardian of the Disks" after going berserk on the Jells.
** Hare has one during "Tiger Meets His Match" when confronted with [[spoiler: what they think is Tiger's Lost Disk]]. UnstoppableRage follows.
* HeroicSacrifice: Near the end of the second season, [[spoiler: Big Blue saves the mortally wounded Pixie by merging with her, giving her new life as a Pixie/Golem hybrid]]. This was immediately followed up by the season finale with [[spoiler: five of the Searchers sacrificing themselves to revive the Phoenix]].
* HeroismWontPayTheBills: The heroes occasionally run into this problem. In "Hare's Trick", Suezo notes that all they do is spend money on their adventures. They avert the problem by entering a tournament. In another episode, Hare notes how inefficient going over a mountain is by pointing out the cost. Hare also looks for ways to raise money, such as harvesting oil from nuts.
* HistoryRepeats: The Phoenix and Moo are destined to battle for as long as they live. Moo realizes this and [[spoiler: destroys himself and the Phoenix]].
* HitFlash: Used a couple times, moreso in the dub.
* HopeBringer: Genki and the Searchers.
* TheHorde: Moo's army of Baddies.
* HumanLadder: In one episode, the group piles up so Suezo can get a better view of the area.
* HumanityIsInfectious: One Henger grew to think for himself outside of his programming, and was cast out of his city for it. In the end he decides to stay behind and help his fellow robots understand free will and compassion.
* HumansAreTheRealMonsters: Humanity, at least in the backstory, has done ''very'' nasty things to Monsters, including creating them to fight in wars, enslaving a colony of Astros, and eventually [[spoiler:nearly wiping out the world by creating Moo]].
* IFightForTheStrongestSide: [[spoiler: Lilim's]] excuse for betraying Durahan.
* IfIDoNotReturn: Genki tasks Mocchi with finding the Phoenix if he doesn't make it back in "Pixie's Defeat".
* IfYouKillHimYouWillBeJustLikeHim: The reason Holly tries to save Naga. He ends up letting go of the edge on purpose.
* [[ImplacableMan Implacable Mon]]: Some of the baddies who went after the Searchers were these.
** Moo himself was one.
* InevitableWaterfall: Seen in "Suezo's Secret Weapon," though the baddies deliberately diverted the raft to a waterfall.
* InsistentTerminology: The villains are always referred to as "Baddies", and the heroic characters are called "Goodies" to match this.
* InstantGravestone: Whenever monsters die they instantly turn into a Lost Disk -- a stone disk gripped in a dead shrub.
* IntangibleTimeTravel: Monol's visions work like this.
* JustAKid: Genki and Mocchi both have to deal with this reaction, but prove themselves over time, Genki by [[BadassNormal fighting right alongside the others]] and Mocchi by learning new attacks and showing how he can hold his own.
* TheJuggernaut: The Melcarba robot. It manages to effortlessly take out a troop of Jaggernauts (not related to the trope), and then relentlessly hunt the Searchers. And none of their attacks nor ''dropping an entire building'' could stop the machine. It's only thanks to the lighting storm, a pole and some last minute quick thinking from Genki that manages to stop it. Holly puts it best after the whole ordeal.
-->'''Holly''': Even Melcarba's no match for the forces of nature.
* {{Keet}}: Genki is aptly-named.
* KillEmAll: [[spoiler:The second season ends with the five main Monsters fusing together to become the Phoenix and sacrificing themselves to destroy Moo, killing Mocchi, Suezo, Golem, Tiger, Hare, Moo, and the Phoenix]].
* KillItWithFire: Undine accidentally burns herself to death.
* KilledOffForReal: [[spoiler: Lilim]]. Even in the third season, she never reappeared.
* LifeIsntFair: Tiger gives a speech about this to Genki combined with a TheReasonYouSuckSpeech.
-->'''Tiger:''' You're a very brave, and very ''foolish'' little human. You rush in head first not bothering to even think of the consequences. You don't understand that sometimes, bravery isn't enough. Life can be ''hard'', little human, hard and ''unfair''--and you must know this. Don't. Be. Reckless. You're young, brave, and you have a good heart--but in this world, that isn't enough. I know that better than anyone.
* LighterAndSofter: The third season comes off as this with the quick reunion of the Searchers and focus shifting to the TournamentArc, the fact that neither goodies nor baddies die, and Durahan's VillainDecay. Perhaps {{Lampshaded}} with the heroes' confidence, as it's outright stated several times that they ''think'' [[spoiler: they can just summon the Phoenix at a moment's notice]] if things get out of control.
* LostInTranslation:
** Like the games, 'Muu' in Japanese means emptiness or darkness. In English we got 'Moo', like the sound a cow makes.
** Mocchi's name is a pun on a Japanese snack food, ''mochi'', with no real equivalent in English. Genki's inspired for the name in the anime by the food his mom gives him. To avert this, the dub calls the food 'sweet cakes', up until Genki names Mocchi when he realizes the monster's name is that 'cake'.
* LostTechnology: The world of Monster Rancher is littered with Lost Disks and Shrines. Occasionally, there may be a robot, flying machine, or even a factory in working condition.
* LukeIAmYourFather: Holly's father turns out to be [[spoiler:the current Moo, or at least his human container.]]
* MadeASlave: Pixie does this to those who cross her.
* TheMagnificentSevenSamurai: "The Courageous Seven" loosely follows the standard formula in one episode. The major difference is instead of defending a small village from attack, it's trying to avert a disaster. Speaking of which, the dub title is probably a ShoutOut to the trope makers.
* MeaningfulName:
** Genki means energy, and he has lots of it!
** In the original Japanese, Muu means emptiness and void.
** Abel, the guy who succeeds Holly's Dad as mayor of her hometown. [[spoiler: He, along with most of the village, is killed by the reborn Moo.]]
* TheMole: In the episode "Undine's Lake," Golem befriends a beautiful water nymph named Undine, who offers the gang fresh fish and shelter. Later on, it turns out she's working for the main villains and she tries to kill Genki and co. Luckily she undergoes a HeelFaceTurn, though RedemptionEqualsDeath,
* {{Mons}}: Along with ''Anime/{{Pokemon}}'' and ''[[Anime/DigimonAdventure Digimon]]'', it was one of the first shows in the genre to be imported to the US.
* MonsterOfTheWeek: Well, being a Mon series with tons of monsters this was inevitable.
* MoodWhiplash: "Tiger Meets His Match": after a CrowningMomentOfHeartwarming, Tiger abruptly shrugs off Mocchi's hug and reveals why he was being so nice and cooperative earlier: [[spoiler: he thought he was getting out of shape and wanted to slim down, hence letting Mocchi ride on his back and volunteering to help]]. [[JawDrop The others are less than pleased]].
* MotiveDecay: Moo suffers from this ''big time''. He starts off desiring [[EvilPlan to rule over the entire world]]. He even [[DaddysLittleVillain wanted his daughter Holly at his side]]. He sought to liberate Monsters [[SlaveRace while enslaving Humans]]. And then... he goes ''[[MoralEventHorizon completely insane]]''. He's become an OmnicidalManiac, who now desires to wipe out all life.
* MrViceGuy: Hare and Tiger are prideful, stubborn, and were originally at odds with the group. They butt heads fairly often.
* MsFanservice: All of the various Pixies.
* MutualKill: The end of the second season has this. [[spoiler:Realizing that the two of them are fated to battle each other as long as they exist, Moo determines that the only way their battle will ever end is if both of them die. So he causes both himself and the Phoenix to explode]].
* NeverSayDie: Justified as Monsters turn into Lost Disks, though the result is the same as death in Seasons 1 and 2. Sometimes it's used to creepy effect, though:
-->'''Pixie:''' ''Disappear''. '''*turns Captain Clay into a Lost Disk*'''
* NicknamingTheEnemy: Genki and his pals refer themselves as the "Goodies" and to Moo's army as the "Baddies". Moo and his officers call the heroes "The Searchers".
* NoHoldsBarredBeatdown: The third season has the gang participating in a tournament and Mocchi is up against a Suezo named Poritoka. Mocchi brutally gets his butt handed to him for a significant portion of the fight and can barely maintain consciousness after it's over.
** Naga savagely beats up Suezo when he tries to fight him, slamming him headfirst into the floor several times.
* NoMrBondIExpectYouToDine: Gali feeds the heroes food and water. The meal isn't rigged, but he uses the distraction to sucker-punch them.
* NoSell: Moo is resistant to pretty much everything, as only the Phoenix has the power to truly defeat him.
* NotAGame: Holly berates Genki for initially acting like Moo's no big deal. Upon seeing some of the long-reaching effects of Moo's evil, it really starts sinking in for him.
* NotSoDifferent: Tiger of the Wind and Hare started off as a thief/con artist respectfully, and both were very {{Pride}}ful and stubborn, resulting in their constantly butting heads and arguing.
* ObfuscatingStupidity: This is partially what allows Hare to get the drop on Tiger in episode 6. He latter attempts this against another foe. Being less merciful, it doesn't quite work.
* OffModel: Episode 10 has this, particularly involving Pixie.
* OminousFloatingCastle: Moo's. it's also used as a means of transport.
* ParrotExposition: Done in episode one, where Holly and Suezo explain their quest to Genki. After Holly states one sentence, Genki repeats it word-for-word, as if the audience had forgotten what Holly just said a second ago.
* PastelChalkedFreezeFrame: Used during several battles. The Pastel Chalked version also ends a few episodes.
* PeopleJars: [[spoiler: We find out that a majority of Monsters were born in test tubes. Moo was engineered to be a SuperSoldier to end the Last War, but was too strong to control]]. This ends up disturbing the characters when they eventually find [[spoiler:a Monster manufacturing plant, with Mocchi asking if ''he'' was born there]].
* PhosphorEssence: Monsters and Genki glow when they are charged with power.
* {{Pirate}}s: Captain Horn and his crew.
* PlotCouponThatDoesSomething: The Magic Stone may be an UrExample; it finds Mystery Disks, points the way to the Phoenix and Moo's body, and [[spoiler: can be used to help Moo regain his full power]].
* PokemonSpeak: {{Averted}}; Mocchi does repeat his own name and variations thereof frequently, but it's more of a very heavy VerbalTic.
** Golem is also guilty of this. "Gol!"
** Various other monsters tend to do it too, especially those in large groups. Zillas, Mocks, Dokus etc.
* PowerGlows: Genki and friends often glow when powered up, and even villains can get this, such as Undine.
* ThePowerOfFriendship: The characters' courage, along with friendship, can be used to make themselves stronger. In the last episode of the second season, Genki summoned the courage of every heroic character on the planet to use in a CombinedEnergyAttack.
* ThePowerOfHate: Moo is empowered by anger and hatred. In the second season finale, when Moo goaded the heroes into hating him to make him stronger, the power of their hatred ''drove him insane''.
* PragmaticVillainy: Moo captured Holly to use the Magic Stone to locate his original body, figuring he could destroy the heroes with it. They rescued her, but by that time he had gotten what he needed to know. Rather than let them find out where he was going or try and stop him in his humanoid form, he simply left them behind so they had no idea where he was.
* PraetorianGuard: A Baddie group of Weeds that accompany Moo. Downplayed that they don't seem particularity badass, but seem to be more ceremonial than anything else.
* ProudWarriorRaceGuy: The three Centaur Warriors.
* APupilOfMineUntilHeTurnedToEvil: The Tainted Cat brothers of "Battle in the Meadow" used to be Kato's apprentices.
* PursuedProtagonist: In-universe, this is how the ''Monster 200x'' opens, with Holly and Suezo on the run from moo's troops.
* QuirkyMiniBossSquad: The Big Bad Four are Moo's top enforcers, and the Searchers defeat them one by one over many episodes.
* RagnarokProofing: The Shrines for restoring the disks are still standing even after the end of civilization.
* RealityEnsues: Genki's excitement at being pulled into the monster world doesn't go over well with Holly and Suezo when he acts dismissive of the very real threat Moo poses. He gets a further wake-up call upon seeing the effects of Moo's actions firsthand.
** Genki may be [[RollerbladeGood great at rollerblading]], but they don't make very good shoes for traveling over unpaved roads and rough terrain. Fortunately, a kindly old couple provides him with some more appropriate footwear, along with a cloak.
* ReallyDeadMontage:
** Allan's Worm and Baku get these.
** [[spoiler:Tiger]] also gets one, though it's revealed he was faking it.
* TheReasonYouSuckSpeech: Tiger gives one to Genki in his introduction.
* RedemptionDemotion: Averted. [[spoiler: Pixie]] is even stronger when she's good than when she was evil.
* RedemptionEqualsDeath: Undine believes this herself, and refuses to let Golem save her from a fire.
* RelativeButton: Moo presses this for both Tiger and Holly at the end of the second season. With Tiger, he taunts him about having to fight and kill Gray Wolf, and for Holly, he says that her father is completely gone and he wishes she could have seen how pitiful he looked at the very end.
* RidiculouslyCuteCritter: Mocchi. And Mum Mew, at least when she's not angry.
* RiverOfInsanity: The Searchers attempt riding a raft across one in "Suezo's Secret Weapon". [[InevitableWaterfall Guess what happens]].
* RobbingTheDead: A troop of Jells decide to take all the Lost Disks that Golem was protecting. They learn the price of desecration the hard way.
* SacrificialLamb: Allan's Worm was the first friendly character to die.
* SaveTheVillain: Attempted with Naga; it didn't work.
* ScarsAreForever: Tiger of the Wind has a distinctive scar across his face, which he retained [[spoiler: after being trapped in a Mystery Disk and reborn]].
* SceneryPorn: This show was animated by Creator/TMSEntertainment in their prime and is ''very'' well-animated. If it's raining, for instance, the characters get a soft, fuzzy outline. Ditto with effects for fire and energy beams.
* SchizoTech: The ancient ruins' technology is a lot more advanced than in the present day. [[spoiler: This is justified by Monol's story]]. And even then for a civilization that could [[spoiler: create monsters and explore space]], they choose to store [[spoiler: said monsters]] on CD-Roms.
* SelfDisposingVillain: In the second season finale, Moo [[spoiler: destroys himself and his arch-enemy, the Phoenix, when he realizes they are doomed to fight in an eternal stalemate.]]
* ShownTheirWork: Across three seasons, every species of monster from both games was seen aside from the Doodle and living Disk.
* SigilSpam: Downplayed. Though most of Moo's troops wear his emblem, it's not placed everywhere in areas they control.
* SimilarSquad: Holly's village had a Suezo, a Tiger, and a Hare, though of different breeds.
* SnowMeansDeath: Tiger and Gray Wolf's battle to the death takes place on a snowy mountain just like the one where they grew up.
* SortingAlgorithmOfEvil: Subverted early on when the group's first major enemies were Pixie (strongest of the Big Bad Four) and Moo himself. Pixie got convinced into a HeelFaceTurn, Moo just [[FinalBossPreview ripped them apart and left until the finale.]]
** It's never explicitly stated who the strongest of the Big Bad Four is. The American version of Monster Rancher censored out a lot of the more violent and action-packed scenes. This had the side effect of making Pixie look much more powerful as the group nearly lost to her, pulling off a win at the last second with a single cherry blossom blizzard by Mocchi. In the uncensored version, the gang won a much more decisive victory with Genki head-butting Pixie to knock the wind out of her, Mocchi unleashing his special attack to knock Pixie into the ruins, and Tiger finally body-slamming into her to end the fight. Nonetheless, the sorting algorithm is still subverted because by Season 3, the heroes fight against Durahan, who's far less powerful than Moo.
** It could be played straight as far as the Big Bad Four goes, since the heroes didn't have their most powerful attacks when fighting Pixie and were only able to knock her out. For the fight with Gali, Mocchi learned the Mocchi Cannon and outright destroyed him. he didn't get a chance to use it on Gray Wolf, but that battle was personal and harder than if they'd all attacked him. For Naga, Suezo's Teleport and the Mocchi Cannon were used, but it didn't kill him. The Mocchi Cannon didn't kill Durahan, either.
* TheStarscream: Durahan to Moo, [[spoiler: and Lilim to Durahan]].
* SternChase: Seen in "Melcarba", with the titular monster tirelessly pursuing the heroes.
* SuperSoldier: [[spoiler: Moo was created to be this]].
* TailSlap: Suezo's primary attack. Gray Wolf also used this, whipping Tiger in the eyes.
* TakeMyHand: Holly tries to save Naga when he's almost thrown off a cliff. [[spoiler:He lets go of the edge himself]].
* TakingTheBullet: Holly pushed Tiger out of the way of a Black Worm's poison dart, but was poisoned herself.
* TertiarySexualCharacteristics: The Seed Sisters wear lipstick to differentiate themselves from other Weeds.
* TomatoInTheMirror: [[spoiler: Mocchi, Suezo, Golem, Tiger and Hare turn out to be the Phoenix's soul split into five pieces. Once brought together they manage to reawaken him.]]
* TookALevelInBadass: Mocchi, Suezo, and Holly.
* ThisIsYourBrainOnEvil: Moo feeds on hatred. Too much drives him ''insane''.
** Gray Wolf's hatred and resentment were magnified by Moo, turning him against Tiger.
* TournamentArc: The third season.
* TrueCompanions: The Searchers.
* TryingToCatchMeFightingDirty: Gray Wolf doesn't care if he does this as long as he wins.
* VillainForgotToLevelGrind: Happened with End Bringer, who curbstomped the heroes in the first battle with them and literally lost the second time due to their increasing courage levels.
* VillainWorld: For much of the first two series. Moo has nearly conquered the planet and the heroes fight a distinctly uphill battle for a long time.
* VillainousRescue: Pulled off in "Magic Stone Mayhem": [[spoiler: after being betrayed by Lilim, the fatally wounded Weed uses the last of his strength to stop Durahan's army before they can execute most of the Searchers via firing squad]].
* VitriolicBestBuds: Hare constantly goads and teases Tiger, while Tiger is disdainful and quick to insult Hare's intelligence. Yet when it comes to the clutch, they can pull off a pretty awesome BackToBackBadasses.
** Illustrated best by the second season episode "Tiger Meets His Match", where Hare lapses into a brief HeroicBSOD when he thinks Tiger [[spoiler: was killed]], followed by an UnstoppableRage.
* VocalEvolution: Genki's voice deepened in the second season, going along with his emotional maturity.
** It got even ''deeper'' in the third season, (as Genki in the dub was played by an actual child actor who went through puberty between the second and third seasons), almost to the point where it doesn't suit his childish appearance anymore.
* TheVoiceless: Alan's Worm and Baku.
* WarIsHell: ''Lots'' of monsters, and a few humans, good and bad, die in this show (with the humans this is mostly off-screen). With friendly characters it tends to affect everyone, even Genki, greatly, and the second season has [[spoiler:the main characters sacrifice themselves]].
* WhamEpisode: Episodes 12 and 13 contain the horrifying backstory of the Monster Rancher world, followed up by Moo kidnapping Holly and revealing to her that he's her father.
* WholeEpisodeFlashback: The episode "After the Rain" fleshes out Holly and Suezo's {{Backstory}}.
** "Monol's Story" gives out the backstory to the Monster Rancher world. It's [[MoodWhiplash very dark]].
* YearInsideHourOutside: Genki was inside the Monster Rancher world for about a year, but only three hours had passed in his world.
