''Valérian'' (later ''Valérian et Laureline'') is a French-Belgian comic book series by Jean-Claude Mézières and Pierre Christin published from 1967 to 2010.

In the 28th century, Earth is the center of a powerful galactic empire, governed along technocratic lines from its capital Galaxity. The basis of Earth's power and civilization is its mastery of TimeTravel, which makes both instantaneous travel and control of history possible. An [[TimePolice elite corps of time travel agents]] has been created so as to maintain order throughout time and space, and Valérian is one of its members.

After a trip to the Middle Ages to capture a MadScientist who was attempting to alter human history, he met a local girl named Laureline and hired her as his fellow agent.

The series has long been suspected to be a key visual influence on ''Franchise/StarWars'', which it predates by a decade. It also influenced ''Film/TheFifthElement'', for which Mézières was actually hired to draw some décors and machines.

A French-Japanese AnimatedAdaptation of the series was released in 2007 titled ''WesternAnimation/TimeJamValerianAndLaureline''.

Creator/LucBesson directed a LiveActionAdaptation movie, ''Film/ValerianAndTheCityOfAThousandPlanets'', starring Dane [=DeHaan=] and Creator/CaraDelevingne in the main roles.
!!This comic book series contains examples of:

* ActionGirl: Laureline.
* AfterTheEnd: The civilization of Galaxity was born of a global catastrophe that destroyed preexisting human civilizations in 1986, when a huge nuclear explosion near the North Pole caused arctic ice shelves to melt, resulting in global warming and a rise in sea levels.
* AmbiguouslyBrown: Valerian, probably because Galaxity's civilization was built by survivors from Earth's old age, all mixed together. Laureline, on the other hand, was recruited by Valerian in Medieval Europe and has distinctly European features.
* AnachronismStew: One mission sends Valérian to pocket dimensions resembling Earth at various points in history, where the presence of anachronisms is a result of sloppy design by the alien intelligence behind it all.
* AnimatedAdaptation: ''[[WesternAnimation/TimeJamValerianAndLaureline Time Jam: Valerian & Laureline]]''.
* AntiHero: At first a regular action hero, Valérian grows into more of an anti-hero over time.
* ArtEvolution: the art style in the early instalments of the series is markedly more cartoonish.
* ArtImitatesArt: The [[http://a21.idata.over-blog.com/0/31/92/83/images-hors-BD/Peintres/Renoir/M-C-V-TT.jpg last panel]] of "On the False Earths" depicts Valérian and Laureline enjoying some time off in 19th century France in a scene that recreates the painting ''Luncheon of the Boating Party'' by Auguste Renoir.
* ArtisticLicenseEconomics: The very existence of the Grumpy Converter from Bluxte necessitates this trope. The creature can multiply any small, precious object hundreds or thousands of times as long as it has enough energy reserves, yet it's treated by everybody as a handy source of currency instead of a highly illegal living forgery machine.
** Treated as such by everybody ''at Point Central'', where shady deals are the standard operating procedure. Laureline is supposed to keep it secret.
** Somewhat averted as said animal is VERY rare, EXTREMELY hard to catch, needs a thorough brainwashing by a team of professionals to actually be useful, and it has rather limited reserves. The costs of acquiring, and then keeping one, offsets their economical impacts. It is the most effective alternative to carrying around enough different currencies in a mission, but in the scheme of things doesn't offset economical balances that much.
* AuthorTract: The authors never waste an opportunity to make a political point.
* BadFuture: What Xombul almost managed to achieve.
* BeardOfEvil: Xombul.
* BlobMonster: The Sufuss are a polymorphous alien species whose default appearance is that of shapeless blobs. Also, the alien entity simply known as The Master is a huge mass of protoplasm.
* CantTakeAnythingWithYou: A formal rule of time travel, and one respected more in the breach than in the observance.
* CasualInterstellarTravel: Justified, since space travel is based on instantaneous teleportation, itself an offshoot technology of TimeTravel.
* ContinuityPorn: The last three volumes of the series bring back numerous characters that had appeared as early as the series' debut.
* CoolOldGuy: "Uncle" Albert.
* CorruptCorporateExecutive: The collective management of both Bellson&Gambler and WAAM, two large multinational firms who tried to make a deal with SpacePirates from the future.
* CrystalSpiresAndTogas: Galaxity's civilization.
* DirtyHarriet: In order to approach two SpacePirates, Laureline dresses up as a call girl.
* ExpendableClone: Valérian gets lots of these in ''Sur les terres truqueés''.
* FanService: Laureline changing clothes are often opportunities to depict her in various states of undress.
* FishOutOfTemporalWater: Averted with Laureline, who, despite being from the Middle Ages, flawlessly adapts to life in the 28th century.
* GainaxEnding: "L'Ouvretemps" wraps up the series by deconstructing it.
* GratuitousEnglish: Often present in the original French version, as well as non-English translations. Sometimes from characters who really have no reason to know any English.
-->'''Schniarfeur:''' Cool man!
* HauntedCastle: Played with. Inverloch Castle in Scotland is supposed to be haunted, but this is in fact because [[spoiler:it houses a time gate]].
* HeroesWantRedheads: Laureline has red hair and a [[FieryRedhead personality to match]].
* HollowWorld: The aptly named ''Country Without Stars''.
* HonestJohnsDealership : the Shingouz.
* HumanoidAliens
* IncredibleShrinkingMan: Happens first to Laureline in "The City of Moving Waters". Valérian later ends up temporarily shrunk as well as a side-effect of impregnating an alien hive mother (see below).
* LandmarkingTheHiddenBase: The New York base of the TimePolice is inside the Statue of Liberty.
* LanternJawOfJustice: Valerian has one.
* LoadsAndLoadsOfRaces: Aliens everywhere! Though there are plenty of {{Rubber Forehead|Aliens}} and HumanAliens, there's a lot of bizarre ones as well.
* LuddWasRight: In "Welcome to Alflolol", the low-tech, environmentally-friendly lifestyle of the natives is depicted as superior to the high-tech, industrial one of the human settlers. However, Alflololians having psychic powers which allow them among other things to space travel without much technology, the {{Aesop}} of the story wasn't about technology levels, but lifestyle choices.
* MadScientist: Xombul.
* TheMonolith: The Wolochs appear as spacefaring black rectangular monoliths. They also happen to be [[EldritchAbomination Eldritch Abominations]].
* {{Neologism}}: The name "Laureline", a fairly popular girls' name in France, was invented for the series.
* NoPlansNoPrototypeNoBackup: Done on purpose in "City of Moving Waters". Valérian and Laureline chance upon a discarded prototype for a time machine, and turn it into a functional one thanks to their 28th-century technological expertise. Once they're done with it, however, they restore it to its previous inoperable state in order to avoid any historical alteration.
* OnlyYouCanRepopulateMyRace: In "Heroes of the Equinox", an alien but human-looking civilization has a single hive mother who must be impregnated anew every generation. Valérian ends up getting the job.
** The entire ending of that story is a CrowningMomentOfFunny.
* PlanetOfHats: Several of them, notably the homeworld of the Shingouz. In "Heroes of the Equinox", Valérian is pitted against three champions, each from a different PlanetOfHats.
* PlanetVille: Rubanis.
* PowersThatBe: Many stories involve shadowy political or corporate powers, such as The Master in "Birds of the Master", the greedy multinational companies Bellson&Gambler and WAAM in "Metro Chatelet, Direction Cassiopeia" and "Brooklyn Station, Terminus Cosmos", the elusive rulers of Rubanis in "The Circles of Power", and last but not least, the Lords of Hypsis whose influence is subtly behind almost every storyline.
* PrecisionFStrike: After staying too long in the 1980s, Valérian begins to pick up time-appropriate swear words which he uses with increasing frequency.
* RubberForeheadAliens
* RuinsOfTheModernAge: "City of Moving Waters" takes place in a flooded, post-apocalyptic New York City.
* SendInTheClones: Expecting a high attrition rate for his mission in "On the False Earths", Valérian was cloned into dozens of short-lived copies. Most of them were expended in one go when the mission manager dressed them up as German soldiers, and sent them to battle in a live-action reenactment of a UsefulNotes/WW1 trench charge.
* SetRightWhatOnceWentWrong: In an [[TheTimeTravellersDilemma interesting dilemma]], preventing the apocalypse from taking place might jeopardize the existence of the characters' civilization.
* SheCleansUpNicely: Laureline is fond of fancy outfits.
* ShoutOut: Prof. Schroeder in "The City of Moving Waters" looks like the title character of ''The Nutty Professor'', a supporting character in "At the Edge of the Great Void" is named Molto Cortes, a reference to ''ComicBook/CortoMaltese'', and the philosopher Chatelard in "Métro Châtelet, Direction Cassiopeia" is a reference to Gaston Bachelard.
* SingleBiomePlanet: Several of them. The most unpleasant one is definitely Zomuk, which is essentially a giant garbage dump for the rest of the galaxy.
* SpaceOpera
* StarfishAliens
* SufficientlyAdvancedAliens: Played straight in "Ambassador of the Shadows", in which said Shadows are an ancient race with godlike powers; played with in "The Rage of Hypsis", in which the Triune God of Christianity turns out to be [[AlienSpaceBats three powerful aliens]] with a bad case of megalomania.
** The Trinity of Hypsis seems to potentially go into [[PhysicalGod Physical Gods]] territory considering the levels of power they possess, especially considering that they are apparently in the lower end of power scale on their home planet, where all the "gods" of the various galatic civilizations seem to reside.
** The fact that they manage to wipe the future of planet Earth from the timeline does imply that they can back their claim of divinity at least to a point.
* TakeThat: The creators did a gentle dig at ''Star Wars'' in one illustration where Valérian and Laureline meet Luke and Leia (circa ''Return of the Jedi'') in a space bar, with the conversation along the lines of:
-->'''Leia:''' Nice meeting you here!
-->'''Laureline:''' Oh, we've been around for a long time!
* TimePolice: The corps of agents Valérian and Laureline belong to.
* TimeTravel: The whole point of the series.
* TranslationConvention: It's taken for granted that every species understands every other species's language.
** Averted: in The country without Stars, an universal translator is evoked; also, both agents use mnemotechnic helmets (first seen in The Bad Dreams),to learn languages when possible before a mission. Due to the characters' job, they soon know enough languages to go around without a need to learn new languages all the time.
