Character sheet for ''Film/IndependenceDay'' and ''Film/IndependenceDayResurgence''.


!The Main Trio

[[caption-width-right:350:Click [[labelnote:here]][[/labelnote]]to see ''Resurgence'']]

!!President Thomas J. Whitmore
->'''Played By:''' Bill Pullman

-->''"Today, we celebrate...our Independence Day!"''

President of the United States and former Gulf War hero. He is initially unpopular due to his perceived softness, but takes charge when the alien threat becomes clear.
%%* AcePilot
* AuthorityEqualsAsskicking: Justified, as Whitmore was apparently a fighter pilot in the Gulf War, and is still relatively young at the time of the invasion.
** As a DoubleSubversion Before the invasion, his presidency is plagued by complaints about how meek a leader he is.
* AsskickingEqualsAuthority: Subverted. He was elected because people thought that as a fighter pilot, he'd be a strong leader. Before the invasion, his presidency was plagued with complaints about how meek he was.
%%* BadassInANiceSuit
%%* BashBrothers: With General Grey.
* BeardOfSorrow: Sports this along with a cane in ''Resurgence''. In addition, he mentions that his brief MindRape with the alien causes him to still see and hear them in his dreams.
%%* BigGood
* ButtMonkey: Before the alien war, Whitmore took a lot of crap from others who either hated his policies or felt that he was too young to run a country. Much of what happens on the news prior to the attack is pretty much everyone badmouthing him.
* ChekhovsSkill: Whitmore's tour of duty as a fighter pilot in the Gulf War [[spoiler:becomes useful when he leads the final attack agaisnt the Aliens]].
* DoNotGoGentle: Referenced in his famous speech, where he said "We will not go quietly into the night!".
* EveryoneCallsHimBarkeep: OK, show of hands, who actually remembered that the character's ''name'' was not "Mr. President" without having to look it up?
* AFatherToHisMen: Becomes indisputably true during his brilliant Churchillian speech right before the final battle.
* FrontlineGeneral: Personally leads the final battle against the aliens, as the world needed a pilot more than it needed a president.
* GoodParents: A very loving father to Patricia.
* HappilyMarried: He and Marilyn are shown to have a very stable and loving marriage.
%%* HumansAreWarriors
%%* IntergenerationalFriendship: With General Grey.
* LastStand: Right before the final battle, President Whitmore gives one of the most memorable speeches in movie history, a speech that seems to be deliberately designed to be similar to Churchill's refusal to surrender.
* NoCelebritiesWereHarmed: Seems to be a combination of UsefulNotes/JohnFKennedy and UsefulNotes/BillClinton.
* NoPartyGiven: The novelization establishes Whitmore as a Democrat, though the film does not state this.
* OurPresidentsAreDifferent: Starts off as a President Peronable, as he's heavily criticized for weak leadership and not taking a hard enough stance for his policies, depending too much on compromise. When it comes time to lead the battle against the aliens, he's a full-fledged President Action.
* ReasonableAuthorityFigure: Upon seeing David again for the first time in years, when David punched him in the head, he immediately says he doesn't have time for this. However, he then decides to give him a minute and after hearing about the countdown, Whitmore immediately orders General Grey to begin evacuating the cities.

[[caption-width-right:235:"Now that's what I call a close encounter."]]

!!Captain Steven Hiller, USMC
->'''Played By:''' Creator/WillSmith

U.S. Marine Corps fighter pilot with aspirations to become an astronaut. Is called to duty when the invaders first appear.

* AcePilot: He's the only member of the Black Knights to survive the first counterattack, which he does by leading his pursuer through the Grand Canyon.
%%* ActionHero
* {{Badass}}: He's the only one who survives the Black Knights massacre and even manages to capture an alien, making his attacker crash in the desert and then knocking him out with a single punch without showing any sign of fear.
* BondOneLiner: Several:
** "Welcome to Earth!"
** "Now that's what I call a close encounter."
** "Just anxious to get up there and whoop E.T.'s ass, that's all, sir."
** (''Before firing the nuclear payload at an alien in the mothership''.) "Nothing but love for ya! Nothing but love!"
* BusCrash: Will Smith opted to not appear in the sequel ''Independence Day: Resurgence'' due to ''Film/AfterEarth'''s failure turning him off to father/son sci-fi. As a result, [[spoiler:the supplementary website [[ War Of 1996]] says Hiller died in April 2007 when a new aircraft built with reverse-engineered alien tech he was test-flying exploded.]]
* CigarChomper: Just look at his pic. As a tradition for his squadron, he carries a cigar in his pocket during missions and lights up afterwards. He even nearly postpones the flight to the mothership because he doesn't have any cigars; luckily, Julius gives him his last two.
* TheFightingNarcissist:
-->'''Jasmine:''' You are not as charming as you think you are, sir.
-->'''Steve:''' [[BadassBoast Yes I am.]]
* HotBlooded: While being usually calm and collected he occasionaly lashes out some angry tirade.
%%* HumansAreWarriors
* ImprobablePilotingSkills: He was able to maneuver a fighter jet through the grand canyon [[spoiler:AND fly an alien craft with only his witnessing it's capabilities as experience.]]
* KilledOffscreen: Died in a [[spoiler:disastrous test flight eleven years after the War of 1996.]]
* LargeHam: Just in the famous desert sequence. Smith sure had a lot of fun in there.
%%* MilitaryMaverick
%%* SemperFi: A Marine F-18 pilot
* TranquilFury: The entire desert scene. Rather than be mad or horrified like everyone else would be, he takes it as a hiccup to his vacation. When Hiller (And to an extent Smith) smelled the [[RageBreakingPoint brine shrimp in the air,]] [[UnstoppableRage he finally snaps and kicks the alien he's dragging with him,]] before calming down and walking.

!!David Levinson
->'''Played by:''' Creator/JeffGoldblum

[[caption-width-right:350:Click [[labelnote:here]][[/labelnote]]to see ''Resurgence'']]


An [[BrilliantButLazy MIT graduate-turned-cable company employee]] who stumbles upon an alien transmission signalling their imminent attack. Also happens to be the ex-husband of Constance Spano.

* AwLookTheyReallyDoLoveEachOther: He and Constance snark on a daily basis, but the reason he went to the white house to warn the president was so that she didn't die in the eventual invasion.
** He ''still'' wears his wedding ring, Constance looks like she's about ready to cry when she finally notices.
%%* BigApplesauce
* BrilliantButLazy: He had the talent and knowledge base to becomes a wealthier engineer, but he was perfectly happy where he was.
* CharacterDevelopment:
** He started out as a BrilliantButLazy cable guy, who hated smoking and berated everyone for minor acts of pollution such as littering. After the invasion he starts smoking cigars, making messes and saving the world using a computer virus.
** Made even more drastic in ''Resurgence'', where we see he's risen from being a cable guy to the commander of the agency responsible for guarding Earth against the aliens.
* IvyLeagueForEveryone: Spent eight years at MIT (Massachusetts Institute of Technology), which is the equivalent in status for math & science.
%%* JewishAndNerdy: His nerdiness ends up serving him well by allowing him to save the world.
%%* NiceJewishBoy
* RankUp: Official material released for the sequel indicates that twenty years later, David is in charge of all the Earth's defenses.
* SmartPeoplePlayChess: He has a very keen interest in playing chess, given that his introductory scene has him playing it. He continues to make references to the game throughout the movie.
%%* WorkingWithTheEx

!U.S Government

!!President Elizabeth Lanford
->'''Played By:''' Sela Ward

!!Jake Morrison
->'''Played By:''' Creator/LiamHemsworth

->'''Played By:''' Creator/PatrickStEsprit

!!Marilyn Whitmore
->'''Played By:''' Creator/MaryMcDonnell

The First Lady.

* HappilyMarried: She and Tom love each other very much.
* IronLady: The novel goes into more detail, portraying Marilyn as a popular figure and being part of the reason Tom is able to accomplish anything.
* PhraseCatcher: Due to Tom's inability to lie, she frequently and affectionately calls him "liar."
* SacrificialLion: She survives the destruction of LA, but is seriously injured when she's found by Jasmine. After Steve rescues them, she's brought back to Area 51 and soon dies after seeing her family one last time.

[[caption-width-right:189:"In case you haven't noticed, we are having a ''little bit'' of a crisis here!"]]
!!Constance Spano
->'''Played by:''' Margaret Colin

%%* AudienceSurrogate
* BrainyBrunette: You don't get as far as Presidential aide without being smart, but she's also the only one who realizes that all the people ''outside'' the Area 51 bunker would be screwed when the aliens arrive.
* FamilyVersusCareer: She went for a career with President Whitmore "wanting to make a difference".
%%* GirlFriday: to the President.
* MistakenForCheating: The reason David punched President Whitmore in the head (before he was President) was because he thought Constance was having an affair with him. She insists she wasn't, and it's implied she's telling the truth.
* PunnyName: The White House Press Secretary with a name seemingly inspired by C-SPAN.
%%* WorkingWithTheEx

[[caption-width-right:200:"Sir, if we don't strike soon there may not be much of an America left to defend."]]
!!Secretary of Defense Albert Nimzicki
->'''Played by:''' James Rebhorn

* TheCassandra: Nimzicki, probably because he has foreknowledge of what was in Area 51, is the only person on Whitmore's staff who advocates an attack on the aliens when they initially appear. His advice is characteristically stupid, but his impression of the immediate threat the invaders pose is the only thing he gets right.
* EvilChancellor: He's the only surviving cabinet member, thus the person to take over in the line of succession if something happens to the President, and tries to be this during the crisis. The novelization even says that he's outright trying to make Whitmore appear as a weak and indecisive leader during a global emergency.
%%* TheNeidermeyer
* HateSink: We're not supposed to like him, given that he tries to have Levinson thrown out of the immediate room when the latter objects to using nukes. This is even more pronounced when he reveals he's known about the alines from the get-go and withheld critical information. He is called out on the latter by General Grey since it would've saved hundreds of American pilots from dying in pointless counterattacks. This gets to the point where a furious and exasperated President Whitmore finally fires him.
* NeverMyFault: Refuses to admit that if he'd come clean about [[spoiler: his knowledge of Area 51, it might have given the Americans some advanced warning, or at least stopped them throwing away countless numbers of their pilots in a futile counter-attack]].
-->'''General Grey''': [[spoiler: You should have told us about this when they first arrived! You should have warned us before we launched a counter-attack that cost us the lives of ''hundreds'' of American pilots!]]
-->'''Nimzicki''': [[spoiler: There was no way we could have known our fighters would have been that ineffective against their attackers!]]
* ObstructiveBureaucrat: Does nothing but provide bad advice to the President, and withholds crucial information (regarding the Roswell crash and Area 51) that could have been more useful had it been divulged earlier.
* SkewedPriorities: It's outright stated in the book that he cares more about his political career and legacy than ''saving the human race from extermination''.
* UngratefulBastard: He's the only one that still acts like an asshole even after many times he's been proven wrong. And maybe even after the aliens were defeated.

!U.S. Military

[[caption-width-right:250:"Is that glass bulletproof?"]]
!!General William Grey, USMC
->'''Played by:''' Robert Loggia

%%* BadassGrandpa
* ConsummateProfessional: The only official who manages to keep a cool head.
%%* CoolOldGuy
* EverybodyCallsHimBarkeep: Much like how President Whitmore is known only as "Mr. President", Grey is referred to by most characters in the film simply as "General."
* AFatherToHisMen Not just his men, he felt it was his own duty to report to Hiller that his hometown was destroyed when these two never met in person prior.
%%* FourStarBadass: Hell yeah.
* IntergenerationalFriendship: With President Whitmore, or as Gen. Grey refers to him, Tom.
* NumberTwo: To President Whitmore. At the beginning of the movie, he requests to stay at the White House alongside the President (it turns out to be lucky. The rest of the JCS were apparently killed by the aliens after they evacuated to NORAD). Throughout the movie, Grey is unfailingly loyal to Whitmore and [[EpilepticTrees might be either the new Secretary of Defense or even the new Vice President at the end]], given the fact that the former VP is dead and the former Secretary of Defense was unceremoniously fired. He ends up succeeding Whitmore as President once his second term expires.
%%* OfficerAndAGentleman: In the sense that he keeps a StiffUpperLip through the whole crisis
%%* OldSoldier
%%* ReasonableAuthorityFigure
%%* SemperFi: A Marine General as Chairman of the Joint Chiefs of Staff.
* TheReasonYouSuckSpeech: Delivers one to Nimzicki over the fact he kept his mouth shut about [[spoiler: Area 51, when that knowledge might have given the Americans some advanced warning about the threat the aliens posed, or at least stopped them from throwing away so many military personnel in a futile counter-attack]].
-->'''Grey''': As the former head of the CIA, you knew about this place! ''When'' were you planning to tell the rest of us?!
-->'''Nimzicki''': It had been deemed ''"Classified"''
-->'''Grey''': [[spoiler: You should have told us about this when they first arrived! You should have warned us before we launched a counter-attack that cost us the lives of ''hundreds'' of American pilots!]]

[[caption-width-right:200:"Welcome to Area 51."]]
!!Major Mitchell, USAF
->'''Played by:''' Adam Baldwin

* DoubleTap: Performs this on a wounded alien after he and several Secret Service agents gunned it down.
* MajorlyAwesome: He has the first confirmed kill of an alien invader, and supervises the evacuation of the refugees before the imminent attack on Area 51.
* ReasonableAuthorityFigure: In spite of being in charge of a highly secret military base, he unlike most fictional characters in such a position is portrayed as a professional soldier whose response to an imminent alien attack is to allow all the unauthorized civilians to take shelter in the underground laboratories and personally take charge in the evacuation efforts.
* TranquilFury: His reaction when he sees the captive alien telepathically attack the President.
--> '''General Grey:''' "Is that glass bulletproof?"
--> '''Major Mitchell:''' "''[[PreAsskickingOneLiner No sir.]]''"

!!Captain Jimmy Wilder, USMC
->'''Played By:''' Creator/HarryConnickJr

Steve's best friend and fellow pilot.
* BlackBestFriend: An inversion, though he still behaves in the trope manner.
* LoveTriangle: He really likes Jasmine too, and Steve is actually cool with that.
* ThisIsGonnaSuck: His wide-eye expression when he sees hundreds, perhaps thousands, of tiny crafts being deployed from the alien destroyer.

!!General Joshua T. Adams
->'''Played By:''' Creator/WilliamFichtner

!Casse Family

[[caption-width-right:250:"Payback's a bitch, ain't it?"]]
!!Russell Casse
->'''Played by:''' Randy Quaid

* AcePilot: While he doesn't seem one initially due to his alcoholism, he's noted to be a Vietnam combat veteran and despite not having flown a fighter in decades has no trouble keeping up with younger pilots and careful with not wasting missiles.
* TheAlcoholic: Ever since his abduction.
* BigDamnHeroes: [[spoiler: "Sorry I'm late, Mr. President!"]]
%%* BumblingDad
* CassandraTruth: He was the first person to warn them that the aliens are gonna kill them all.
%%* TheCuckoolanderWasRight: And he rubs it in.
* DadTheVeteran: A veteran of UsefulNotes/VietnamWar.
* HeroicSacrifice: [[spoiler: His last missile jams before he can take out the primary weapon of the alien ship. Instead he flies his plane directly into the weapon, setting off a chain reaction that destroys the entire ship.]]
* PapaWolf: In the special edition there's a scene where he rushes a group of armed guards and slams a high-ranking doctor against the wall to get him to attend to his dying son.
* PreMortemOneLiner: [[spoiler: "Hello, boys! '''[[HesBack I'M BAAAAAAAAAAAAAAAAAAAAAAAAAAACK!!"]]]]'''
* YouHaveToBelieveMe: Once the aliens start showing up, Russell tries to warn people. By flying over city hall and dropping leaflets.

!!Miguel Casse
->'''Played By:''' James Duval

* MissingMom: His mom has apparently been dead for some time. It's also suggested in the special edition that Russell is actually his stepdad, as he bitterly calls him "the man who married my mother."
* PetTheDog: For all his disagreements with Russell, Miguel does express pride in him after his father [[spoiler: sacrifices himself to destroy the alien destroyer]].
-->'''Mitchell''': What your father did today was very brave. You should be proud of him.
-->'''Miguel''': I am.
* PromotedToParent: After his mother died and with Russell suffering from PTSD, he takes responsibility for looking after his younger siblings.

!!Alicia Casse
->'''Played By:''' Lisa Jakub

* MustNotDieAVirgin: She tries to lose her virginity on the first night of the invasion. In the special edition, she meets a nice boy who says that if they die, they'll both die virgins

!!Troy Casse
->'''Played By:''' Giuseppe Andrews

* TheDiseaseThatShallNotBeNamed: In the special edition, he has a very vague disease which requires expensive medicine or he could die. Whatever it is, it's hinted that it also killed his mother.


[[caption-width-right:250:"So what are you waiting for? Hmm? My social security will expire, and you'll still be sittin' there."]]
!!Julius Levinson
->'''Played by:''' Judd Hirsch

%%* BadassGrandpa
* BewareTheSillyOnes: When he's not being a PapaWolf he's a bit of a CloudCuckoolander, talking about looters and Area 51. However when shit hits the fan he's the first to pull a shotgun out....accidentally at his son, but the thought counts.
%%* BigApplesauce
* CigarChomper: Like Steve, Julius loves his cigars, much to David's displeasure. He ends up giving Steve his last two when he refuses to go on the mission to the mothership without a "victory dance."
* ConspiracyTheorist: He believes that the government captured a spaceship back in the 50s, and turns out he was right.
* CoolOldGuy: Gets some of the best lines of the movie, isn't afraid to shout down the freaking President and his staff [[PapaWolf when he feels that they're being disrespectful and ungrateful to his son]], and in general seemed like a character who it'd be pretty fun to be around.
* JewsLoveToArgue: He argues with his son during the drive to Washington.
* PapaWolf: Memorably, he shouts down the country's leaders when they disrespect his son aboard UsefulNotes/AirForceOne.
--> '''Julius:''' ''You'd all be dead now if it wasn't for my David!''
%%* PluckyComicRelief
* SmallRoleBigImpact: Julius may seem unassuming as David's sarcastic father, but he's responsible for getting David to Washington, which convinces Whitmore to evacuate, inadvertently directs Air Force One to Area 51, and gives David the idea of a computer virus to defeat the aliens.
%%* YiddishAsASecondLanguage

[[caption-width-right:220:"You are not as charming as you think you are, sir."]]
!!Jasmine Dubrow-Hiller
->'''Played by:''' Vivica A. Fox

* CharacterDevelopment: It has been confirmed that Jasmine has risen from being a stripper to a ''hospital administrator'' in the twenty years between films.
* HookerWithAHeartOfGold: Well, technically an ''exotic dancer'', but this is probably the closest trope that fits to her portrayal.
* MamaBear: When things start blowing up she goes from Stripper to Sprinter getting her son the hell out of there.
* SingleMomStripper: Unlike most examples of this trope, she dances by choice and enjoys the work and the money that comes with it

[[caption-width-right:220:"David! David, what's the point of having a beeper if you're not gonna turn it on?!"]]
!!Marty Gilbert
->'''Played By:''' Harvey Fierstein

David's boss.

* BenevolentBoss: Upon hearing that one of the spaceships is heading for New York, he immediately tells everyone to drop what they're doing and get to safety.
* CampGay: He's extremely camp, and Harvey Fierstein is a very flamboyant homosexual. Not to mention he kisses David on the lips in a deleted scene.
* EveryoneHasStandards: When David warns him that the aliens are going to attack, he immediately goes to call his mother, his brother, his housekeeper, his doctor, and his lawyer...[[EvilLawyerJoke before deciding against warning his lawyer.]]
* FamousLastWords: "Oh crap." Said [[spoiler:right before he is crushed by a car that was flung by the advancing wall of fire.]]
* NiceJobBreakingItHero: When David warns him [[spoiler: about the impending attack, Marty urges his mother to head to her sister's place in Atlanta. It's later mentioned that Atlanta was destroyed in the next wave of attacks on major cities]].

!!Dylan Dubrow-Hiller
->'''Played By:''' Ross Bagley & Jessie Usher

* GenerationXerox: Like his step-dad, he grows up to be a fighter pilot.
* TagalongKid: Like Patricia, he follows his mother through the ruins of LA.

!!Patricia Whitmore
->'''Played By:''' Creator/MaeWhitman & Maika Monroe

* GenerationXerox: Like Dylan, she's taken after her father and has become a fighter pilot.
* TagalongKid: Follows her father from Washington to Area 51.

[[caption-width-right:220:"Look! They're opening up!"]]
->'''Played By:''' Kiersten Warren

* ComicallyMissingThePoint: When Jasmine brings up her "bad feeling" in the special edition, Tiffany says that she also had a bad feeling when she left to apply for a job in Vegas. Jasmine was right, since she didn't get the job and lost all her money in the casinos. But, Tiffany retorts that at least she wasn't in LA for the '94 earthquake.
* FamousLastWords: "It's so pretty..." as the underbelly of the alien ship begins to open up.
* TooDumbToLive: Completely ignores Jasmine's "bad feeling" and heads to the party welcoming the aliens. She's one of the first shown to be vaporized.


[[caption-width-right:279:"The last 24 hours have been really exciting!"]]
!!Dr. Brackish Okun
->'''Played by:''' Creator/BrentSpiner

An eccentric scientist who conducts research on the aliens at Area 51.

* AdmiringTheAbomination: Shows a very enthusiastic interest in the aliens and their technology, even after the damage they caused.
* ConvenientComa: Dean Devlin has implied that Okun was put into a coma instead of killed during his run-in with the alien, hence his surprise return in ''Resurgence''.

!!Dr. Isaacs
->'''Played by:''' John Storey

* TheMedic: Serves as medical officer of Area 51, as he treats Troy Casse and tries to save Marilyn Whitmore. In the novel, he expresses excitement at getting to examine a live alien, but he's forced by Russell to look after his son first. This ends up saving him when the alien wakes up.
* NumberTwo: He's subordinate to Okun in the research project.

!!Lucas Foster
->'''Played by:''' John Bradley

A farmer who hires Russell to spray his crops.

* PetTheDog: According to the novelization, he hired Russell out of sympathy for him and his children. Unfortunately, Lucas could only tolerate him not doing his job for so long.

[[folder:The Aliens]]
!!The Aliens
[[caption-width-right:306:"Die. ''Diiiiie.''"]]

->'''Played By:''' Creator/FrankWelker

An unnamed nomadic species, they come to Earth hoping to harvest our planet's resources. And to do that, they need to wipe out the human race.

* AliensAreBastards: Played entirely straight. It is made abundantly clear that they intend to wipe us out and steal our planet's resources.
** Dean Devlin plainly explained his view of the aliens in a documentary: "They don't like us, they don't hate us. They're the new tenants, and we're the cockroaches."
* AlienInvasion: One of the most visually impressive ones ever put on film.
* BigBad: Subverted. There is no supreme leader of the aliens that we see, and being a telepathic race, it's likely they have no such leader. The closest we see to an alien leader is a dock controller.
** Hinted at in the trailer for ''Resurgence'', where Whitmore is being controlled by the alien prisoners and says "She has arrived..."
* CombatTentacles: Their bio-mechanical suits sport several long flickering tentacles that they can use to kill people with.
* DangerouslyGenreSavvy: They target major cities and important military facilities such as NORAD first, and employ force fields that can ''repel nuclear explosions''.
* FlyingSaucer: The City Destroyers, 15-mile wide ships that serve as their primary attack craft. Unlike other saucers, which are shiny and chrome, the surface is heavily detailed with [[ greebles]] and there is a parabolic indentation that indicates the front of the ship.
* HoistByHisOwnPetard: One of their [[TrojanHorse long-lost attacker crafts]] brings down their shields and nukes them from within.
* HordeOfAlienLocusts: They travel from planet to planet and take every natural resource they can find for themselves. The president even describes them as such.
* HumanoidAliens: Somewhat. They have two arms, two legs, a head, and a torso, but that's where, appearance-wise, the similarity ends. However, Dr Okun does point out that they breath oxygen, are equally sensitive to temperature and that beneath their suits, they aren't really any more or less frail than any average human. In short, they are [[NotBigEnoughForTheTwoOfUs perfectly suited for living on Earth.]]
* IdiotBall: You'd think that aliens would be immediately suspicious that one of their aforementioned long-lost craft (which we see from closeups has gone through visible man-made modifications) suddenly showed up at the mothership.
* KeystoneArmy: Living up to its name, the mothership is the key element of the alien invasion force. It serves as the command and control center, and also directs all power and shield functions. Okun mentions that the captured attacker didn't even activate until the mothership arrived. The novel makes it clear that when [[spoiler: the mothership is destroyed at the end, all the destroyers and attackers lose power and are quickly downed.]]
* LackOfEmpathy: They never show signs of compassion or even remorse towards the thousand (or more) victims they cause. When Whitmore tries to find a peaceful solution with one of them, the alien simply answers that there will be "no peace" and the only thing humans can do is "die."
-->'''Whitmore''': What is it you want us to do?
-->'''Alien''': Die...'''''DIE!'''''
* LaserGuidedKarma: After exterminating millions of lives and potentially whole other alien races to get their resources, they are finally taken out by one of their targets and have their own resources stolen.
* MonumentalDamage: "They like to get the landmarks."
* NotQuiteDead: Right before the destruction of the mothership, the aliens were able to send a distress signal. And twenty years later, their reinforcements arrive.
* NotSoInvincibleAfterAll: Okun indicates that it's only really their superior technology that gives them an advantage; without it they're as susceptible to injury and death as humans. [[spoiler: The point is further driven home when their destroyers and fighter craft are stripped of their shields and rendered vulnerable to human weaponry]].
-->'''Whitmore''': Can they be killed?
-->'''Okun''': Their bodies are just as frail as ours. ''[indicates the specimens from Roswell behind him]'' These two died in the crash, this one a few weeks later. You just have to get through their technology, which I am sad to say is, far more advanced.
* OhCrap: If their faces were capable of displaying emotion, this would likely be their reaction to [[spoiler:seeing the timer on a nuclear missile count down to zero right before their eyes. Though that one alien who's right next to the bomb might also [[WorthyOpponent admire the humans' cleverness]]]].
* OrganicTechnology: It's stated in the novel that their ships are not forged, but ''grown''. Especially their biomechanical suits, which Okun theorizes is an ''entirely different animal'' that they breed, slaughter, then hollow out to use as armor
* PlanetLooters: They are a race of galactic nomads that travel from planet to planet consuming its resources and wiping out any native inhabitants that stand in their way, and now have designs on Earth.
* PuppeteerParasite: Can use human bodies to communicate audibly by wrapping the tentacles of their biomechanical suits around throats.
* {{Telepathy}}: Implied to be how they communicate with each other.
-->'''Okun''': No vocal cords. We're assuming they communicate with each other through some other means.
-->'''David''': You're obviously not thinking about hand signals and body language, are you?
-->'''Okun''': No, this is some kind of extra-sensory perception. [[TropeNamer Telepathy]], say.
* QuizzicalTilt: One of them does this when Steven and David decide to reveal themselves [[spoiler: before they fire the nuke.]]
* StandardSciFiFleet: Their armada consists of a mothership that serves as their home base, destroyers which are their primary offensive weapon, attackers that are utilized as defense against enemy fighters, and transports to bring their ground forces to the planet.
* ToServeMan: Invoked in the novel. Whitmore asks Okun what the aliens eat, which causes everyone to immediately picture humans being rounded up and marched into slaughterhouses. However, Okun says that the autopsy found nothing in their stomachs, so their actual diet is unknown.
* WeComeInPeaceShootToKill: The first part averted. They don't want peace.
