->''"In the beginning we were a group of nine. Three are gone, dead. There are six of us left.They are hunting us, and they won't stop until they've killed us all. [[TitleDrop I am Number Four]]. I know that I am next."''

Part of the ''Literature/LorienLegacies''.

Number Four is an alien from [[DoomedHometown the planet Lorien]], which was destroyed by another evil race, [[AlwaysChaoticEvil the Mogadorians]], whose sole purpose is planetary extinction. Number Four wasn't the sole survivor, as there were eight others, along with their [[TheObiWan guardians]], who escaped the planet's destruction. These nine remnants are destined to use their inner powers to defeat these evil intergalactic terrors, but they must survive long enough to master them. The aliens seek out the survivors, one by one, in order of their number. Numbers one through three have been killed.

Number Four is next.

'''''I Am Number Four''''' is a YoungAdult sci-fi novel written by Pittacus Lore, the PenName of James Frey (of ''A Million Little Pieces'' [[TheOprahWinfreyShow infamy]]) and Jobie Hughes. Published in 2010, it had the film rights picked up by Creator/DreamWorks over a year before it was even released. TheFilmOfTheBook was released in February 2011, starring Alex Pettyfer, Creator/DiannaAgron, Creator/TeresaPalmer and Creator/TimothyOlyphant. Both the book and the film proved to be decent hits; the book spent six weeks on the children's chapter of the ''[[AmericanNewspapers New York Times]]'' Bestseller List, while the film has already made back its $50 million budget.

While the film series has been shelved due to relatively-poor performance at the box office, the novel series has continued, and is planned to extend as far as six books.

The book series has gained Frey (further) infamy and controversy even before it hit shelves: Frey's publishing house, Full Fathom Five, commissioned ''I Am Number Four'' specifically to write "the next ''{{Twilight}}''" or "''Literature/HarryPotter''" with the idea of being adapted into a [[CashCowFranchise film franchise]] [[MoneyDearBoy from the onset]] and has been accused of being akin to a fiction sweatshop and producing works of derivative nature. ''New York Magazine'' [[http://nymag.com/arts/books/features/69474/ published an article]] giving more insight into Frey's thought processes behind the series and Full Fathom Five.
----
!!Tropes in ''I Am Number Four'':
* ActionGirl: Number Six
* AlwaysChaoticEvil: The Mogadorians exterminate all life on a planet (including all members of the species from that planet that escape), then find another planet to wipe clean.
* AncientAstronauts: The Loriens and Mogadorians. Even quoted in the film.
* BadassLongcoat: All of the Mogadorians wear them.
* BadassNormal: [[spoiler: Sam, who "plays a lot of Xbox"]].
* BettyAndVeronica: Played with. Certainly Sarah, whose defining character trait is that she takes pictures, feels mildly threatened when Number 6 appears in the film. She should because as she's busy cowering in fear due to her powerlessness, Number 6 is [[AdaptationalBadass wrecking people left and right]]. But considering how John's race [[LoveAtFirstSight mates for life with one other person]], Sarah really has nothing to worry about.
* BloodKnight: Number Six, but when [[AxCrazy Number Nine]] comes along she seems like an amateur compared to him.
* BoringInvincibleHero: Four has so many superpowers that he's basically undefeatable, at least for the JerkAss jocks at his school. [[spoiler: literally with Six, thanks to [[AWizardDidIt magic.]]]]
* ChekhovsBoomerang: Sam [[spoiler:bringing along guns]].
* TheChosenOne: Four is, obviously, made out to be so.
* ConspicuousTrenchcoat: The Mogadorians.
* DisappearedDad: Sam's, and John's to an extent - but he claims Henri as his father.
* TheDogIsAnAlien: [[spoiler: John/Number Four's dog Bernie Kosar shapeshifts into a more monstrous, distinctly more extraterrestrial creature (that still resembles a dog) known as a Chimera to pull a BigDamnHeroes, engaging another alien monster in combat and eventually killing it.]]
* DyeOrDie: Number Four has to dye his brown hair blonde when he moves to Paradise, Ohio.
* EasilyForgiven: Mark, despite being an utter Jerkass throughout the entire story, paint bombing Sam and John's lockers, sending his men to attack John and kidnap Sarah, gets off with an insincere apology at the end.
* FiveManBand:
** TheHero: John Smith/ Number 4
** TheLancer: Sam
** TheBigGuy/ TeamPet: Number 4's dog Bernie.
** TheMentor: Henri
** TheSmartGuy: Sam once again for playing Xbox.
** TheChick: Sarah
** TheSixthRanger: Number 6
* FollowTheLeader: A very [[{{Bishonen}} pretty]] [[GenderFlip boy]] moves into a small town and starts a relationship with a [[GenderFlip girl]], [[ParanormalRomance except he has superpowers]], [[Literature/{{Twilight}} which complicates things]]. And his mouthy, socially ostracized friend is called [[TransformersFilmSeries Sam]], who believes in [[TransformersFilmSeries ancient astronauts]]. Number Four even ends the movie narrating that [[TransformersFilmSeries Earth is his home]] now, [[strike: and though they are worlds apart, there's more to them than meets the eye]] so he has to protect it.
* FourIsDeath
* GiantFlyer: They're more like giant gliders, but [[spoiler: the Mogadorians' secret monsters]] are still this.
* HumanAliens: The Loric.
* HumanoidAbomination: The Mogs.
* HumanoidAlien: See HumanAliens and HumanoidAbomination above.
* IJustWanttoBeNormal
* IKnowMortalKombat: Sam.
* ImpaledWithExtremePrejudice: Number Three. [[spoiler: And Henri. Four also narrowly avoids this]].
* JerkAss: Mark, the Football Jock and Sarah's ex, is completely without any redeeming qualities, is little more then a violent thug who attacks other people constantly, and ends up getting easily forgiven at the end.
* KinkMeme: There's a new one [[http://community.livejournal.com/lorien_kink/ here]], for both the movie and the book, as far as they overlap.
* LeParkour: Number Four is fond of this trope.
** And Number Three, implying that Lorians are all badass. The opening sequence of the film was maybe the most awesome part. It does help that Greg Townley, Damian Walters' protégé, [[CastTheExpert played three]].
* LoggingOntoTheFourthWall: Sadly averted; [[http://www.they-walk-among-us.com They-Walk-Among-Us.com]] only redirects to the film's website.
* MissingMom: Number Four's parents are both dead, but he mentions to Sarah's family that his parents are just separated.
* NamedAfterSomebodyFamous: Bernie Kosar, the dog named after a former [[UsefulNotes/NationalFootballLeague NFL]] quarterback.
* TheObiwan: Henri.
* PetMonstrosity: The Mogadorians' pets. [[spoiler: Also, Bernie Kosar. He manages to take down one giant flying monster, and only gets a hurt paw out of it. Number Six takes out the second one with some help from Four]].
* PowerGlows
* ProudWarriorRace: Implied with the Mogadorians. The Mog leader mentions “where I'm from, men ''work'',” (not to mention his hunting trophies).
* TheQuisling - The guys from the "They Walk Among Us" website.
* RescueIntroduction: Number 6.
* ShapeShifting: [[spoiler: Apparently, the Chimera can change form]].
* SuperpowerLottery: Number Four.
* TeamPet: Bernie Kosar, [[spoiler: prior to his upgrade into a PetMonstrosity]].
* TookALevelInBadass: [[spoiler:Sam]] near the end, when he [[spoiler:takes up a Mogadorian blaster rifle to protect himself and Sarah]]. He "[[IKnowMortalKombat plays a lot of Xbox]]."
** [[spoiler: Bernie when he transforms into the chimaera]].
** Not to mention Number Four himself when his powers emerge.
* YouAreNumberSix: Played straight enough in the books where the Loric appear to have no proper names in their own language and narrator Four/John actually refers to himself as 'Four.'

!!Tropes specific to the novel[[note]]Tropes for the other novels can be found ''[[Literature/LorienLegacies here]]''[[/note]]:
* AlternateLandmarkHistory: The first example of this pops up about the Ancients.
* BigBad: Setrakus Ra (not named in the film).
* ChekhovsSkill: Four being fire-retardant crops up [[spoiler:twice: at Mark's party and the final fight]].
* ColourCodedForYourConvenience: The good guys use blue bullets/power/sword. The bad guys use green lasers.
* ElementalPowers: The Loric horoscope at the end of some editions of Book 1 (essentially the Western horoscope with exotic names) alludes to this. Like, those born under fire signs are most likely to have Lumen as a legacy.
** The cover of the book also carries an elemental motif relating to characters with large roles in the novel: Fire, shown by a [[PlayingWithFire Flaming]] [[FireIsRed orange-red sun]] for Four and his Lumen (which comes with heat/fire resistance.)
* EverythingIsOnline: Actually played fairly realistically; one of the things that keep Number Four from staying in one place is that whenever something big happens to him that exposes the fact that he's an alien is because people record his powers and upload them to Website/YouTube.
* {{Kayfabe}}: The very first page of the book is a "disclaimer" stating the events depicted in the book are real. Also the author bio states the "Pittacus Lore" is the ruling elder of Lorien currently in hiding.
* MissingMom: Number Four's parents are both dead.
* MyNaymeIs: Henri. [[JustifiedTrope Justified]] because the Loric accent (which he hasn't really lost) is said to resemble French, so he just has a French name to go with it. (This causes some consternation for Sam's mom, who hears his accent and unsuccessfully tries to converse with him in French, in which she is fluent.)
* SequelHook: [[spoiler: The book reveals that the Chests contain various rocks, jewels, and other implements that allow the Garde to develop their powers. Four only takes the Lumen out and has no idea what the globes actually do. Not to mention it finishes with the fight.]]

!!Tropes specific to the film:
* AdaptationalBadass: Number Six trades in invisibility from the book for teleportation in the movie.
* BigDamnHeroes: Number Six.
* BloodlessCarnage: Instead of gore, the alien characters that die turn to dust and explode in a shower of ash. Averted by the GoryDiscretionShot of the janitor, where you see the automatic mop sweeping his blood off the floor.
* ChekhovsSkill: [[spoiler:Those DeflectorShields ain't just for lookin' cool]].
* ColourCodedForYourConvenience: The good guys use blue bullets/power/sword. The bad guys use red bullets.
* DeflectorShields: Number Six.
* DisneyDeath: The supposed [[TearJerker tragic]] death of [[spoiler:the dog]] turned out to be this.
** [[spoiler:This shouldn't have surprised anyone; when we last see the dog during the climax, it's wounded, but it doesn't turn to dust like all other aliens that die in the movie. Therefore, it's obvious even before it pops up again in the last scene that it survived]].
* DistractedByTheSexy: Sam upon seeing Six. In fact, the distraction works to break him out of a panic attack.
* EverythingFades: All aliens (conveniently) leave no corpses. [[spoiler:This is probably a substitute for Henri's [[DueToTheDead funeral pyre]] from the novel.]]
* EverythingIsOnline: Actually played fairly realistically
** Implied to be one of the things that keep Number Four from staying in one place is that whenever something big happens to him that exposes the fact that he's an alien is people record him: in the film, a clip got sent to a conspiracy site.
** Henri also found a lot of [[spoiler:information about Sam's dad]].
** Sarah has a photo blog, and dedicates effectively a tag to pictures of John. They immediately get taken down by Henri, and even she doesn't seem to notice the lack.
* EvilIsHammy: Kevin Durand had some fun playing the Mog leader.
* {{Expy}}: Every Mogadorian (in the film) looks like a gill-nosed [[Literature/HarryPotter Lord Voldemort]].
* FauxAffablyEvil / LaughablyEvil: The leader of the Mogs delivers some of the funniest lines in the film.
* FlashStep: Number Six, particularly in the movie where she can teleport.
* ForTheEvulz: The Mog leader scares the crap out of a little boy in an adjacent car for no other reason than this.
* GoryDiscretionShot: The deaths of the "They Walk Among Us" guys and the janitor all happen off-screen as well as the death of Number Three's guardian, who's yanked through the door of their hut by one of the [[spoiler:lizard glider creatures]].
* ItsPersonal: [[spoiler:Number Four points to the red-eyed Mogadorian and tells Number Six: "He killed Henri, I want ''him''."]]
* KineticWeaponsAreJustBetter: Realistically averted: a shotgun is more likely to knock the MadeOfIron bad guys on their ass, and flinging large heavy items at them will probably slow them down, but it takes turning their own overpowered {{BFG}}s on them to actually take them out.
* LuckilyMyShieldWillProtectMe: [[spoiler: Actually more of DeflectorShields, until Number Six uses it along with her own body in the climax to protect Number Four and herself]].
* MadeOfIron:
** The only things that seem to be able to kill a Mog is a Mogadorian blade or one of their weapons.
*** Somewhat [[JustifiedTrope justified]]. The Lorien weapons we see amount to a slightly over-sized dagger, and a slightly over-sized energy pistol. The Mog weapons we see are a [[{{BFS}} nastily serrated 3-foot sword]] and various high-energy rifles that either pump out ridiculous amounts of machine-gun-style rounds or single massive bursts. About what you'd expect from [[PlanetOfHats an entire race dedicated to]] [[AlwaysChaoticEvil wiping out other races for no apparent reason other than being sadistic]].
*** The Mogadorians don't destroy planets just because it is said that they ruined their own planet and need resources to survive.
** Sarah's ex has some elements of this as well. He's launched into a second floor window hard enough to crack the glass with his face, then falls back to the ground, and yet he's completely uninjured at the conclusion of the movie.
*** [[CastingGag He is a]] ''[[Series/{{Supernatural}} Winchester]]'' after-all.
* MissingMom: Number Four's parents are both dead, but he mentions to Sarah's family that his parents are just separated. Also, Sam has lived with his dad and stepdad but no mom is ever mentioned.
* MundaneUtility: Number Four's glowing hands. Aside from using them to [[spoiler:recharge Six's powers]], he uses them mainly as flashlights.
* MyNaymeIs: The film avoids this issue entirely. Whilst Henri's name is [[SpellMyNameWithAnS spelt with an 'i']], it is pronounced like the English "Henry," and he has no unusual accent whatsoever. This may have been done to avoid WhatTheHellIsThatAccent, or to cut down on the [[InfoDump info-dumpage in the prologue.]]
* ObliviousJanitorCut
* OhCrap: Number Six gets two of these: one when an [[spoiler:energy grenade gets thrown at her]], and the second is when she realizes [[spoiler:Four is about to give the leader Mog a PineappleSurprise]] (in slow motion, no less). Sam also has one when he sees [[spoiler:the lizard creatures]] jumping out of the truck, followed immediately by another one when [[spoiler:Bernie Kosar shape-shifts]].
* OohMeAccentsSlipping: Sam (portrayed by British-Australian actor Callan [=McAuliffe=]) is a repeat offender of this trope, but most notably in the garage scene. British actor Alex Pettyfer slips up as well, but much less frequently.
** In the DVD bonus feature about Number 6, Australian Teresa Palmer claims that one of the things she liked about the role was being able to use her own dialect.
** At least with the latter, it can be assumed that he either has a somewhat odd combination accent due to extensive travel or that he's faking an accent to fit in better with the Americans.
*** The same for Palmer's Number Six.
* OutOfTheInferno: Number Six after blowing up Number Four's old house. Justified in that Number Six can shield herself from fire.
* PineappleSurprise: [[spoiler: Number Four kills the Mogadorian leader by using his powers to set off all of the leader's bullets while they're still strapped to his chest.]]
* SequelHook: [[spoiler:The movie end with Number Four and Six searching for Numbers 5-7-8-9 and Sam's dad. We also never saw what's in that box]].
* SurprisinglySuddenDeath: In the beginning of the film.
* UnflinchingWalk - Number Six after setting fire to Number Four's old house to such a degree she walks ''in'' the explosion.
* UnwillingSuspension: [[spoiler:Henri]].
* VillainsOutShopping: The Mogs keep their secret weapons sated with supermarket turkeys.
* YouAreNumberSix: Played with. It's averted in that the numbers are not actually used for ''names'', but as target designations. However, it's deliberately invoked in Number Six's case, who identifies herself as "Number Six" (except one snarky comment to Sam that her name is "Jane Doe") and refers to John only by his number.
* YouHaveOutlivedYourUsefulness: The two conspiracy theorists, one of whom is forced to swallow what looked like a miniature version of a Sentinel Sphere from ''Film/{{Phantasm}}''.
