4It is the end of the 21st century and the [[UsefulNotes/SovietRussiaUkraineAndSoOn Soviet Union]] has gone on to encompass the globe.
5
6There is no disease (except the flu), no shortage of anything, and no private property. SovietSuperscience has gone on unopposed to give us [[FasterThanLightTravel faster than light spaceships]], {{timetravel}}, and all manner of other wonders. However, this new society faces many external problems, having to deal with "less developed" planets, SpacePirates, and aliens.
7
8Written by Creator/KirBulychev, and highly popular in Russia and the countries of the former Soviet Union, the books feature adventures of a young girl, Alice (Alisa) Seleznyova and her friends. [[Characters/AliceGirlFromTheFuture See the list here.]] There have been several adaptations.

44----
45!! Tropes common to the series:
46* ActionGirl:
47** Iria Gai. Raised as a WrenchWench ultimate tomboy, then met a guy, turned out SheCleansUpNicely, and she became a housewife... That is, unless someone hits the BerserkButton. Then, she's a MamaBear taken up to eleven.
48** Alice herself. Sometimes, at least.
49* AdultsAreUseless: Often Alice solves a problem adults have repeatedly failed to solve (such as the mystery of the Empty Planet in ''A Girl From Earth'').
50** Subverted in some installments where Alice fails, and adults (like regular police) save the day (for instance, in ''The War With Lilliputians'', she wouldn’t have survived for long without Granny Lucretia and Puccini-2). However, while she can fail at actual fighting, she always solves the mystery.
51* AIIsACrapshoot: One of the planets had a few robots survive a starship crash there years ago. They started building duplicates for themselves until the resources of the entire planet ran out. They would have probably gone to do the same on other planets, but no one provided them with starship blueprints.
52** Played straight in ''The Rusty General's Island''; the squad of old 20th-century military robots, accidentally activated by researchers, mindlessly follow the preset war-fighting program - despite being at least partially sentient. Ironically, it is revealed that the war those robots were programmed to fight never actually started, and they were just forgotten in an old storage facility.
53** Subverted in ''The Captives of An Asteroid''; while this seems to be the situation at first, the alien robots are perfectly sane and have resorted to desperate measures just to maintain their degrading asteroid generation ship and descendants of its crew. It turns out that the robots have done so well that their creators have become completely dependent on them and slowly degraded to a near-brainless state after centuries of idleness.
54* AlienNonInterferenceClause: The End of Atlantis.
55* [[AliensSpeakingEnglish Aliens Speaking Russian]]: Zig-zagged. Many aliens (Rrrr, Gromozeka, Rat etc.) are fluent in it, however, TranslationConvention is commonly applied: the usual lingua franca in space is the Cosmolingua, and there are stories set on other planets where mostly the planets' native languages are used (such as ''Literature/AlicesBirthday'', ''Literature/TheCityWithoutMemory'' etc.). But sometimes, aliens or creatures from the legend era speak perfect Russian with no explanation provided.
56* AloofLeaderAffableSubordinate: [[SubvertedTrope Subverted]] in ''The Star Dog''. Dobrets (whose name literally means "a kind guy") is the more personable minion of evasive and paranoid General Besf. [[spoiler:As it turns out, they are the same person]].
57* AncientAstronauts: ''The End Of Atlantis'' features a lost colony under the Pacific Ocean. Another book has Alice finding a crashed starship underwater, and, apparently, another from four million years ago was found in a desert.
58* ArbitrarySkepticism: Several cases of it across the series, though, to be fair, it's more the fault of CanonDiscontinuity than the characters. To name a few: in ''One Hundred Years Ahead'', Alice says invisibility is unscientific (despite having once used an invisibility cap ''herself''); in ''The Star Dog'' and ''Alice and the Pretenders'' (both among the last books of the cycle), shapeshifters are described as something phenomenal and new for the crew of the ''Pegasus'', while the series has already featured more of these than one can count, most notably, the recurring BigBad Rat.
59* AttackOfThe50FootWhatever: The space pirates’ invasion of Brastak, the inhabitants of which are generally the same size (and roughly the same shape) as domestic kittens from Earth.
60* AuthorFilibuster: Quite often, mostly about history.
61* BarefootSage: Downplayed; the wise Chinese professor Lu Fu from ''The Kindness Ray'' wears only light sandals even in cold weather, probably as a way to show asceticism and/or [[EccentricMentor nonconformism]].
62* BewareTheNiceOnes: Quite a few of the good guys.
63** Alice is a sweet, friendly, easy-going girl, which doesn’t stop her from beating galaxy-level villains left and right.
64** GentleGiant Gromozeka may not be so gentle if his friends are in danger...
65* BizarreAlienBiology: Tons of examples. Aliens range from relatively human-like with only a few differentiating traits (the purple-eyes, six-digited Vesterians, the bluish-skinned Krinians) to completely extraordinary for a human’s eye (the residents of Kromanyan who resemble huge waterpots on legs, shapeshifters such as Rat or the people of Zavydkovaya and Millenium). And that’s without getting started on the non-sentient fauna.
66* BondVillainStupidity: Quite often.
67** Special point for ''The Kindness Ray'', when villain used the abovementioned ray to grow a monster predator plant to kill the prisoners. He apparently never realised that under the influence of said ray, his monster simply could not harm anyone.
68* BoundAndGagged: Happens from time to time to Alice and her friends, for example, in ''Twilightsons the Vampire''.
69* CanonImmigrant: Werther the robot was a CanonForeigner in ''Series/GuestFromTheFuture'' whom the fans immediately adored. After that, he made small cameos in several later-written books.
70* TheCavalry: Alice sometimes is rescued by it, though mostly she is on her own. She even lampshades it in ''Twilightsons the Vampire'', when she thinks that she has reached the point where, in the movies, the cavalry usually appears on the horizon, but there doesn't seem to be one in her case.
71* ChildSoldiers: In ''The Secret of the Black Stone'', Alice, along with other children is drafted as one against her will.
72* CommonTongue: Cosmolingua, an interplanetary language known in the entire civilized galaxy.
73* DarkerAndEdgier: Opinions differ, but almost everyone agrees that ''Literature/TheVoyageOfAlice'', ''One Hundred Years Ahead'', ''Literature/AMillionAdventures'' (except for the first part), ''Literature/TheCityWithoutMemory'' and ''Ghosts Don't Exist'' stand out for their much darker tone.
74** ''The Kindness Ray'' is darker than the rest of the series to a completely ridiculous degree. Unlike the other books, where late-twenty-first-century Earth is a post-scarcity CrystalSpiresAndTogas utopia with NoPoverty, no wars or crime, this novel depicts South-East Asia as a dirt-poor land of {{Banana Republic}}s where drug barons are rich, powerful and maintain private mercenary armies.
75* DeathWorld: ''Literature/LilacSphere'' features one.
76* DeceptivelyCuteCritter: In the novella ''The Golden Bear Cub'', there is the eponymous bear cub. It is so adorable that nobody even bothers to remember it was found on a planet where no other animals lived. [[spoiler:It turns out to be a banished tyrant with brainwashing abilities]].
77* DinosaursAreDragons: Mostly averted, though there's one story centered around a new dinosaur species with dragon-like abilities.
78* ADogNamedCat: Alice's pet cat is called Mouse, because he is grey and was very tiny as a kitten.
79* DolledUpInstallment: ''Captives of Asteroid'' started as an unconnected idea for a Soviet-Japanese anime. The idea was never carried out, so Bulychev made it into an Alice story - still one with a Japanese character.
80* TheDreadedDreadnought: No one want to mess with Galactic Patrol Cruisers, and when one (finally) appears, it is usually Game Over for bad guys (and reason to panic). On the other hands, they doesn't seems to be very good in chasing the fleeing pirates...
81* EarlyPersonalitySigns: The very first short story of the series features Alice as a three-year-old. She refuses to go to sleep in time, her father says he'll phone Literature/BabaYaga if Alice continues to be naughty, and the girl is extremely interested and [[ThreatBackfire begs him]] to do so as she would love to meet the hag. That foreshadows Alice's plucky, adventurous and rebellious character that would develop by her preteens and early teens (her age throughout most of the series).
82* EternalEnglish: The galactic CommonTongue, at least, is unchanged from thousands of years ago.
83* ExplosiveBreeder: The space pirates attempted to destroy the atmosphere of an entire planet by unleashing air-eating worms fitting the trope. Also, see AIIsACrapshoot.
84* ExtraDigits: Iria Gai has 12 toes because she is actually an alien from the planet Vester (the inhabitants of this planet are distinguished from humans by their lilac eyes and six toes on both feet).
85* ExtremophileLifeforms: An airless chasm on an asteroid converted into a GenerationShip is inhabited by "ice dragons" -- octopus-like creatures possibly inspired by the Lucky Starr example. There are also sapient species fitting it -- for example, a hotel on one planet was described as too hot to touch despite a thousand layers of insulation.
86* TheFateOfThePrincesInTheTower: The young princes are rescued and brought to the future.
87* FantasticDrug: ''A Girl From Earth'' features a planet where a drug was invented allowing time travel. At first, people were going to the future to check what will happen, but then grew afraid of it and all started traveling back to the best moments of their life. Within a few years, the entire planet was a slum.
88* FasterThanLightTravel: Spaceships can fly between different star systems in mere days or hours. Later books mumble something about gravitons.
89* FlatEarthAtheist: A the start of ''The Fairy Tales Preserve'', both Alice and her father refuse to believe in fairy tale creatures despite actually seeing them in reality. They get better, though. This is in fact lampshaded by the dwarf who seeks assistance from Alice:
90-->'''Sven:''' If I told you that I come from planet Pataliputra, where everyone is the same height as me and wears red hoods, would you believe me?
91-->'''Alice:''' I would.
92-->'''Sven:''' And when I tell you that I'm a dwarf, you don't believe me?
93* FreeRangeChildren: Alice and her friends are allowed to wander around unsupervised from the age of seven. By the time she is ten, she already has traveled to other planets (sometimes with no adults or any sort of supervising) and been through a huge number of life-threatening situations.
94* FriendlyEnemy: The space pirates in later books. Lampshaded several times.
95-->'''Rat''' (to Alice): I'm your enemy for life. If I ever kill you, who will [[BreakingTheFourthWall Kir Bulychev]] write his books about?
96* FriendlyScheming: Alice's grandmother Lucretia, being TheTrickster and a sorceress, really loves to do this.
97* FromNobodyToNightmare: [[spoiler:Garold]] from ''The Underground Boat''.
98* FullyClothedNudity: In one book, Alice is hitchiking wearing only shorts -- which even have a ''pocket'' -- and is repeatedly referred as naked. Granted she is topless but she is only twelve -- and before that she ran though a city in the same clothing, with no comments. Justified since [[DeliberateValuesDissonance the one talking to her is a robot actor programmed to believe he's a 19th century peasant.]]
99* GaiasVengeance: If you intend to hunt or dig mines on Penelope, be prepared that one day your city will be leveled by an unnaturally localized earthquake.
100* GentleGiant: A huge alien Gromozeka, who looks like a cross between an elephant, a shark, and an octopus, is a good friend of Alice and her father.
101* GiantEnemyCrab: The dog-sized cameusi from ''The End of Atlantis''.
102* GoneHorriblyRight: The [[spoiler:memory erasure field]] from ''Literature/TheCityWithoutMemory''.
103** The Super Cake from ''The Underground Boat''.
104* GottaPassTheClass: In ''The Class Repeaters'', Alice uses an experimental time machine and accidentally skips six months of her life. The school headmaster announces that it will be impossible for her to pass after missing two-thirds of the school year and she will have to repeat third grade. However, Alice's friends don't want to study on without her, so they all demand to be allowed to repeat the year as well. Finally, she devotes her summer to studying with her friends' help and successfully passes the third-grade exams in September, making it to year four.
105* HappinessIsMandatory: Usurper Zovastr's reign.
106* HatePlague: ''Literature/LilacSphere'' features one, stored in titular spheres.
107* HeinousnessRetcon: The recurring SpacePirates duo Rat and Jolly U are a lot crueler in the first three books that feature them. They use blackmail and torture, occupy peaceful planets, and even try wiping out entire planets' population. Further on into the franchise, they suddenly become much nicer without anyone InUniverse acknowledging it. In the later books, for example, Alice muses that Rat and Jolly U would never imprison anyone for the sake of obtaining secrets of new technology (never mind that it's ''exactly'' what happens in ''Literature/TheVoyageOfAlice''), and Rat is furious at planetary tyrants who spent their lives conquering and oppressing others (having apparently forgotten he did the same some books earlier).
108* HeroicSacrifice: Werther in ''Series/GuestFromTheFuture''. Blue Beard in ''Draconosaurus''.
109* HoistByHisOwnPetard: The creators of the HatePlague wiped themselves out after being subjected to it.
110* HumanAliens: Many alien characters are either humans or very similar to humans. In fact, one book starts with the statement that most aliens are human like.
111* HumansAreSpecial: According to Rat in ''A Planet for Tyrants'', as of late XXI century Earth is ''the only'' planet in the Milky Way "where nobody takes bribes, there are no cheaters or even politicians".
112* KillAndReplace: One of the books features an adopted son of an emperor who learned he won't inherit the crown. He assassinated him, and forced a law that everyone is to wear [[HappinessIsMandatory smiling]] masks.
113* KillerRabbit: The titular critter in ''The Golden Bear Cub'' is a completely adorable and seemingly vulnerable alien bear cub with innocent purple eyes and unclear planet of origin. [[spoiler: He is later revealed to be Vyprakhol, a former genocidal warlord who had subjected his own planet to a horrific ReignOfTerror, was overthrown and spent decades on the run from the survivors of his regime wanting to get revenge. Vyprakhol's cuteness allowed him to avoid any suspicion from his human hosts, study human languages and technologies and develop mind control techniques against humans.]]
114%% * KillerRobot: many times.
115* LaserGuidedAmnesia: ''Literature/TheCityWithoutMemory'' reveals that [[spoiler:the entire planet of Krina was subject to this, causing its civilization to collapse. Remnants of amnesia-inducing energy are still being used to erase people's memories as punishment.]]
116* LazilyGenderFlippedName: Iria Gai is a daughter of an inventor who wanted a son as an assistant. He wanted to name him Iriy.
117* LighterAndSofter: Some darker stories have been rewritten for younger readers. For example, ''The Sorcerer and the Snow Maiden'' is a rewrite of ''Ghosts Don’t Exist'' (which some consider to be the darkest book of the franchise) and ''The Pirate Queen on the Planet of Fairytales'' is based on the fourth part of ''Literature/AMillionAdventures''.
118* LilliputianWarriors: Quite a lot of them in ''The War Against Lilliputians''. However, all of them are really human-sized, having been shrunk by technological or magical means.
119* LivingMoodRing: Indicators are animals that changes color depending on their emotions, such as turning yellow when mistrustful, dark green when content, and transparent to show admiration.
120* LoopholeAbuse:
121** One of the main plot points of ''The Planet for Tyrants'' features a former tyrant that was kicked out from his planet, and, in accordance with a general rule, he was allowed to take one thing of his choice with him. So he took a famous and treasured children's railway from his planet, hoping one day he'd be summoned back and would bring the railway back as a gift. The other tyrant managed to smuggle a mermaid as his slave the same way (he chose a trumpet and hid the mermaid inside it).
122** In ''The End of Atlantis'', Poseidon, seeing the danger to the inhabitants, points out to [[LawfulEvil Hera]] that this is the situation where she, as the head of station, is authorized to use the "sacred" blaster lying in the safe. She does. Then the heroes [[OhCrap realize]] the regulations don't specify that the blaster must be used to deal with the ''particular'' danger in question.
123* LostColony: ''The End of Atlantis'' features a research colony cut off from its homeworld for unknown reasons.
124* {{Lunacy}}: The cameusi are only agressive during the full moon, despite living half a kilometer underwater.
125* MacGuffin: Many, most notably the Mielophone from ''OneHundredYearsFromNow''. Also "the absolute fuel" (whatever it means) in ''Animation/TheMysteryOfTheThirdPlanet''.
126** It's only "Whatever it means" in the cartoon. The book explains it's an extragalactic invention which will allow ships to be a hundred times as fast. Not exactly something you want SpacePirates to get their hands on - or the rest of the galaxy not to have.
127* MadeOfIndestructium: In ''Animation/TheMysteryOfTheThirdPlanet'', the captain's ship has been in the pirates' hideout for four years, and they didn't cut it open. [[Literature/TheVoyageOfAlice The book it's based upon]] claims that wasn't from lack of trying. Also, the final part of ''Literature/AMillionAdventures'' features a passenger ship invulnerable to pirate weapons, with a robot stewardesses to match.
128* MeanwhileInTheFuture: Time travel works this way in the series. Changes only happen when the travel ends or the connection to traveller is severed.
129* MissingMom: Sometimes stated to be a space architect. Must be a workaholic.
130* MuggedForDisguise. Happens with '''children''' in ''The Star Dog''.
131* NakedPeopleAreFunny: Sometimes, modesty has to take a backseat when lives are at stake.
132* NeverAcceptedInHisHometown: In ''The War With Liliputs'', Alice reminisces on this: she is hailed as a savior on many planets, but at home she is "just a girl". Well, in some books she is a capable genetics researcher and at least respected for that, but her adventures don't seem quite as known.
133* {{Objectshifting}}:
134** In ''Alice and the Enchanted King,'' the main villain's entire scheme depends on transforming people into dolls.
135** In ''The Secret of the Black Stone,'' Hrem kidnaps children by turning them into the titular black stones.
136** In ''The Sorcerer and the Snow Maiden,'' a retelling of Ghosts Don't Exist for younger readers, Snow Maidens get turned into dolls.
137** In ''The War with Lilliputians,'' it's mentioned that Rat escaped from prison by turning into a vacuum cleaner.
138* PrankPunishment: In ''The War with Lilliputs'', when Alice and Pashka try to fend off Granny Lucretia by telling her that they have to care after "skunusiks" (a fictional breed of animals), Lucretia pretends to believe them and creates holographic images of fantastic monsters to convince them that their lie came to life.
139* RidiculouslyFastConstruction: Houses are grown (using some coral-like bacteria) within hours.
140* SapientShip: Gai-do is definitely one, to the point of considering himself an actual relative of Iria. However, other spaceships exhibit traits of it as well.
141* SeriesContinuityError: In spades. The author eventually confessed to never rereading his books, which led to him being unable to determine even his main heroine's age and date of birth.
142* ShapeShifter: Rat. There are at least four possible explanations for his powers offered at different points, sometimes within the same book (see SeriesContinuityError above): either he is a [[LatexPerfection master of disguise]], or he uses hypnotism, or he really has a genetic ability to shape-shift, or he uses shape-shifting pills stolen long ago from a planet where they are produced.
143* ShowingUpChauvinists: A villainous/TheMole example: when Alice infiltrates a juvenile delinquents' school, she becomes the best student, in particular, by excelling in subjects usually reserved for boys, such as fighting dirty. When she first shows up to fight, the teachers allow her to participate because they think [[WouldHitAGirl defeating a girl]] would be amazing training for the boys.
144* ShrinkRay: At least two books have such containers.
145* SlidingScaleOfIdealismVsCynicism: Firmly on the idealistic side, though the danger of being too trusting are honestly explored.
146* SpacePirates: The recurring antagonists, Rat and Jolly U.
147* SparedByTheAdaptation: [[spoiler: Joan of Arc, who lives (a dummy is burned instead)]].
148* SpoiledBrat: Aphrodite from ''The End Of Atlantis'' is the last child born in a LostColony. She was spoiled rotten, and is still spoiled rotten at the age of ''ninety''.
149* StarfishAliens: While most sapient alien species have humanlike intelligence and are able to freely communicate with humans, they may look... somewhat weird. Walking watering cans or giant worms are not unheard of.
150* TheSwarm:
151** ''Prisoners of the Yamagiri Maru'' has a swarm of mutant fish caused by 20th-century nuclear waste.
152** ''The End of Atlantis'' has cameusi, dog sized GiantEnemyCrab species from which one must hide behind steel doors whenever they are agressive, otherwise they'll eat you alive.
153* TalkingAnimal:
154** The govorun (talker) birds are essentially parrots with perfect memory and capable of interstellar flight.
155* The titular dog from ''The Star Dog'' qualifies, though it can only remember one word at a time.
156* TemporalParadox: Occasionally occurs. In ''Literature/AlicesBirthday", for instance, the titular heroine [[spoiler:saves the civilization of one planet from death by travelling back in time and changing the past]]. She does this during [[spoiler:an archeological expedition to the ruins of said civilization]]. Go ahead, sort that out.
157* TemptingFate: "Father, what can happen to me in 21st century?". Well, the whole series, including SpacePirates, KillerRobot attacks, facing one EvilOverlord after another...
158* {{Terraforming}}: In ''The Adventures Of Alice'' it is mentioned that one of the Captains works on Project Venus. Apparently, this is the first stage of terraforming the planet in question... by dragging it away from the Sun.
159* ThatsNoMoon: In ''Literature/LilacSphere'', the titular artifact comes from an artificial planet created to escape an exploding sun.
160* ThereAreNoTherapists: Well, at least not on Earth. [[AngstWhatAngst Not that Alice would ever need one]].
161* ThreeLawsCompliant: In one of the books, Alice encounters a squad of old soldier robots, and the concept is so alien to her she believes their behavior is a malfunction.
162* ThouShallNotKill: Alice never kills her opponents, even though she is sometimes armed.
163* TheTimeOfMyths: Pops up often in ''Literature/TheLilacSphere'' and especially in the later books, as some distant past from which all myths have originated.
164* ToyTransmutation:
165** In ''Alice and the Enchanted King'', the main villain's entire scheme depends on transforming people into dolls.
166** In ''The Sorcerer and the Snow Maiden'', a retelling of ''Ghosts Don't Exist'' for younger readers, Snow Maidens get turned into dolls.
167* VillainousGlutton: Jolly U is implied to be one (in ''Literature/TheVoyageOfAlice'', he claims his main goal is to have as much to eat and drink as he wants), but is only ever explicitly shown to be one in ''Series/GuestFromTheFuture''.
168* VideoPhone: In wide use starting from the very first short story.
169* UnexplainedRecovery: Jolly U suffers a DisneyVillainDeath in the end of the first book featuring him. He appears in several more after that, alive and well, with no explanation.
170* UniquenessDecay:
171** In ''One Hundred Years Ahead'', unsanctioned time travel, let alone messing with the past, is explicitly forbidden for anyone who doesn’t work at the Institute of Time and isn't qualified. The whole second part with several characters going to the 20th century is only possible because 1) the institute is closed and empty because of a holiday 2) Rat and Jolly U melt its wall with a blaster, and that's how they (and Kolya, and Alice) can get inside. Several books later, time travel is almost as mundane as space travel, and changing the past goes from "forbidden", to "tolerated through gritted teeth if it has already happened", to "approved if it's for the better".
172** In the early books, intergalactic travels are considered pretty dangerous and epic journeys, which only some heroes dare to attempt. In the later books, they are pretty much mundane. Justified, because the plot device in ''Literature/TheVoyageOfAlice'' is exactly the fuel that make fast intergalactic travels possible.
173* UsedFuture: ''Literature/TheCityWithoutMemory''.
174* WeWillHavePerfectHealthInTheFuture: In the time where the books are set, humans have cured every known disease, and even the common cold will be cured soon. They also enjoy better health and fitness in general, "better fitness" as in somewhat super-strength, -speed, and -agility.
175* WorthlessYellowRocks: Most of the societies are moneyless. One of the stories features Alice looking for a replacement for a 1.5 kg gold nugget she took from the school's museum and lost. Since she has plenty of friends, the next day she comes to school with her dad carrying twelve times the required amount.
176* WrongGenreSavvy: Alice's friend Pavel is often this, believing himself to be the KnightInShiningArmor ActionHero. In reality, when he succeeds getting through some especially dangerous adventures, he does so by using his brains rather than his strength.
177* YouAreGrounded: Happens in ''The War With Liliputs''.
178* {{Zeerust}}: Since Bulychev's 21st century is based on beefed-up Soviet aesthetics, that's kind of a given.
179* ZerothLawRebellion: ''The Prisoners of the Asteroid'' features a GenerationShip with a robotic crew taking care of the organics. The latter are quite moronic after centuries of idleness.
