''Starship Troopers 2: Hero of the Federation'' (2004) is the first of two DirectToVideo sequels to Paul Verhoeven's 1997 version of ''Film/StarshipTroopers''. Unlike the first film's epic MilitaryScienceFiction story, this is more of a contained SciFiHorror.

After a disastrous engagement on a Bug world, a group of Mobile Infantry soldiers flee to a deserted Federation outpost, finding only a few custodians and a disgraced soldier in lock-up. They reactivate the electrified defense perimeter, buying them some time for a rescue ship to arrive. It soon becomes clear that the Bugs have infiltrated the place in the form of {{Puppeteer Parasite}}s and plan to take over the Federation's central command.

!!This film provides examples of:

* AlwaysChaoticEvil: In a PerspectiveFlip the Bugs see humanity as this, regarding them as a virus.
* AnyoneCanDie: The film features an EnsembleCast of roughly a dozen named troopers, and just about all of them are killed off by the end, with [[spoiler:[[PregnantBadass Sahara]]]] the SoleSurvivor.
* AuthorTract: Surprisingly not done in the commentary for this film, where the film-makers point out that everyone assumes the movie is about [[UsefulNotes/TheWarOnTerror Iraq]], but the script was written long before that war started.
* TheBigGuy: Two of them in the form of Tor and Brick. Tor has the boisterous BloodKnight, if slightly dim personality commonly associated with the trope while Brick has the build and carries a smartgun-esque {{BFG}}. Fittingly, they're [[ThoseTwoGuys often paired together]].
* BodyHorror: Sergeant Ari Peck gets this like you wouldn't believe. Because he's been infected by the Control Bug for the longest, his physical condition degrades to the point his skin looks plagued, his eyes turn bloodshot, and his body begins to fall apart. By the time Griff collects him to start infecting the troopers, he can't even stand on his own (one of his legs falls off as Griff carries him, in fact). When Griff removes the top of his head, he plucks out a fully matured Control Bug that looks big enough to have outright replaced Peck's skull and spinal column.
* BottleEpisode: This film stands apart from the other two ''Starship Troopers'' live-action films because the action is confined to a single base for the majority of the film, along with a ToneShift to sci-fi horror instead of military science fiction.
* TheBrigadier: General Jack Gordon Shepherd subverts the [[WeHaveReserves totalitarian style]] of the (film universe's) Terran Federation by [[YouShallNotPass staying behind with a select few troopers]] to cover the retreat of the rest of the platoon. Miraculously, he survives this [[spoiler:and turns out to be TheMole, under the control of a PuppeteerParasite.]]
* CoolBigSis: Sahara fills this role to Otter, since he's the youngest, least experienced, and has trouble fending for himself. She consistently looks after him and comforts him when he starts cracking under pressure. She notably fights back tears when she has to kill an infected Otter in self-defense later in the film.
* DarkerAndEdgier: This film abandons the BlackComedy and military satire of the first film, in favor of playing straight sci-fi horror.
* DistressCall: The troopers are able to send a distress signal early on, with most of the plot centering on the troopers slowly being overcome by {{Puppeteer Parasite}}s one by one while waiting for their retrieval boat.
* TheDragon: Corporal Joe Griff, one of the infested troopers, assumes the role for General Shepherd after he's infected with the Control Bug. He's depicted as the smartest of the infected and is the one who carries out much of the planning. Fittingly, he's the last infected trooper Dax has to deal with before confronting Shepherd.
* DwindlingParty: Of the entire platoon, roughly a dozen named characters survive the initial third of the film as all the {{Redshirt}}s are killed off, and those remaining troopers end up infected and/or killed by the Control Bugs as the film goes on. Only Dax and Sahara make it to the end, but Dax opts to stay behind and die via HeroicSacrifice, leaving Sahara as the SoleSurvivor.
* EnergyWeapon: The movie featured strobe-light weapon props because [[SpecialEffectFailure they couldn't afford real guns]]. Incidentally, [[RealityIsUnrealistic everyone complained that the guns didn't look like they were shooting "lasers"]].
* FamedInStory: [[spoiler:Dax]], at the end. Played for irony, as the Federation trumpets him as the champion of the very ideals he was shown to be very cynical towards in life.
* FanDisservice: A hot blonde female trooper walking around naked? Hell yeah. The said trooper also covered in blood and being infected with a bug in her brain? Yeesh.
* {{Foreshadowing}}: Done in a very subtle manner, with the medic going straight for the sugar cubes when they come to the mess hall. (Those infected with the parasite are later seen eating the sugar cubes as well.)
* FourStarBadass: General Shepherd. [[spoiler:He eventually becomes the movie's BigBad after he gets [[PuppeteerParasite infected]], and gives the heroes a pretty nasty HannibalLecture.]]
* HumanityIsInsane: Because the Arachnids are a HiveMind, humanity's individuality is abhorrent to them. Speaking through its host body, one makes it clear why the Arachnids are fighting a GuiltFreeExterminationWar.
-->"[[PunyEarthlings Poor creatures]]. Why must we destroy you? I'll tell you why. Order is the tide of creation. But yours is a species that worships... the one over the many. You ''glorify'' your intelligence... because it allows you to believe '''[[BlueAndOrangeMorality anything!]]''' That you have a destiny. That you have a right. That you have a cause. That you are [[HumansAreSpecial special]]. That you are [[HumanityIsSuperior great]]. But in truth, you are ''born'' '''insane'''. And such ''misery''... cannot be allowed... to spread!"
* IgnoreTheFanservice: Captain Dax, a disgraced but still badass veteran soldier, is approached by a female trooper who wants to bed him in order to implant him with an [[PuppeteerParasite alien parasite]]. He rejects her advances and instead [[PhysicalFitnessPunishment orders her to do 200 push-ups]] so she can work off all her "excess energy" as he nonchalantly walks away.
* IronicEcho: The recruiter identifies a mother's infant son as "fresh meat for the grinder". Said mother is not amused.
* IronicNurseryTune: Sandee, [[spoiler:under the control of a PuppeteerParasite]], sings "Itsy Bitsy Spider" before trying to take out Dax and Sahara with [[TakingYouWithMe a pair of live grenades]].
* IwoJimaPose: Used in the opening. And then subverted with a MatchCut to a flag, similarly positioned, with a small group of ragged troopers rallying around it trying to hold off a [[ZergRush bug swarm.]]
* JustFollowingOrders: Dax levels a pretty powerful ReasonYouSuckSpeech on [[ThePoliticalOfficer Lt. Dill]] after he uses this excuse.
-->'''Dax:''' Well, that's good, but you [[ThinkOfTheChildren forgot about the children]].\\
'''Dill:''' ...What?\\
'''Dax:''' Cowards; they always hide behind two things: orders and children.
* KissOfDeath: One of the PuppeteerParasite-like aliens is transferred this way, from a female soldier who was [[HoneyTrap walking around stark naked]].
* MeatPuppet: [[PuppeteerParasite Control Bugs]] take over an entire outpost of [[RedshirtArmy Mobile Infantry]] soldiers and pit them against the main characters.
* MythologyGag: The Control Bugs first appeared in ''WesternAnimation/RoughnecksStarshipTroopersChronicles''.
* TheNeidermeyer: Lieutenant Pavlov Dill was one of these, though he's more incompetent than mean. He's also basically ThePoliticalOfficer in the unit, which makes his soldiers detest him even more. Dax is quick to call him a coward who hides behind rhetoric. Although, when Sahara confides in him about her psychic visions, [[HiddenDepths he tries to help her as best he can]].
* NervousWreck: Otter, the platoon's newcomer, doesn't hold up well under pressure and mentally shuts down at the sight of his fellow troopers being killed by the Arachnids.
* NewMeat: A soldier says "Grow up big and strong, we need fresh meat for the grinder" to a newly-born child ''in the arms of its mother''.
* OrificeInvasion: The movie introduces a breed of bugs that enter through the mouth to control the humans (it was also a convenient way to save on the special effects).
* PropagandaHero: Captain Dax is hailed as a true "Hero of the Federation" after his death. In reality, he detested the Federation and what it stood for. Before the heroes stumble across him, Dax was disgraced and arrested for killing his superior officer because he refused to carry out his illegal orders.
* PsychicPowers: Lieutenant Dill has psychic abilities as well. [[InformedAbility sort of.]] At the very least, he can "sense" oncoming swarms of bugs. [[ActionGirl Sahara]], too. When she tells the lieutenant that she's pregnant, he informs her that pregnancy has been known to enhance psychic abilities.
* PunyEarthlings: Played straight: when the {{Puppeteer Parasite}}s take over a new host, they become much harder to kill.
* PuppeteerParasite: The plot revolves around the Bugs infiltrating the human camp with these type of bugs at a remote outpost.
* ReasonableAuthorityFigure: Pavlov Dill is a [[TheNeidermeyer self-important jerk]] who makes a big deal out of his own not-so-extraordinary psychic powers and is dismissive of Sahara for failing her psychic assessment test. However, once Sahara does convince him that she is a psychic, he becomes quite supportive and tries to help her interpret the visions she's been having. He then tries to take action against the PuppeteerParasite bugs but by then, it is too late. At least he was DefiantToTheEnd.
* RedOniBlueOni: Tor and Brick. Tor is loud, gung-ho, and eager for a fight whereas Brick is more level-headed and keeps his cool under pressure. Fittingly, they were often partnered together.
* SarcasticTitle: While Captain Dax was a genuine war hero, he hated the Federation and would have detested the epithet bestowed on him post-mortem.
* ShoutOut: Captain Dax, who detests the hypocrisy of a military bureaucracy that wastes the lives of its soldiers in fruitless battles brought on by unjust orders, is almost certainly named after the protagonist of ''Film/PathsOfGlory'' who shared similar ideas about his own army.
* SlashedThroat: Dill gets offed this way by a bug-controlled Otter.
* SpeechImpediment: Peck has a habit of stuttering his speech, and this gets worse as his infection progresses. It's unknown if he's always had it or it's a result of the Control Bug deteriorating his body.
* TatteredFlag: Shown in an ironic transition shot. After a propaganda reel espousing the virtues of the war against the Arachnids, a proud and neat Federation flag turns into the flag flown by a battlefield unit, torn and weathered.
* TheyWouldCutYouUp: Lieutenant Dill uses these exact words when he finds that the rest of the soldiers ([[PuppeteerParasite all infected by mind-control Control Bugs]]) have infected Gen. Shepherd with the Arachnids' plan being to send him back to the Federation so he can infect other Federation leaders and take over the world. During the following speech Dill doesn't realise there's another infected soldier creeping up behind him.
-->'''Pavlov:''' You bastards... you are all under arrest for murder, sedition, for treason against the Federation. Oh, you're going to pay... because we're not going to kill you... oh no... you see, we got special places for things like you... where they cut you up, but [[AndIMustScream they keep you alive]] when they cut you up... so they can see what makes you tick, and then what makes you sick! And I will be there, oh yeah! I'm going to be there when they see--" (threat cut short by infected soldier [[KilledMidSentence cutting his throat]]).
* ThinkOfTheChildren: Mocked by the cynical, disgraced Captain Dax when one of his superiors berates him for having refused to follow illegal orders. According to Dax, cowards hide behind one of two things: [[JustFollowingOrders orders]] and children.
* ThoseTwoGuys: Tor and Brick, the platoon's resident [[TheBigGuy big guys]] are usually fighting alongside each other; they're also among the last of the infested troopers to be fought in the climax.
* ToneShift: ''Hero of The Federation'' is a sci-fi horror film instead of the satirical war film its predecessor was.
* VasquezAlwaysDies: The only person to get off the planet alive is a pregnant woman. Must be [[MamaBear all those maternal instincts]] keeping the bugs away.
* VitriolicBestBuds: Tor and Brick exchange light-hearted banter, even as they're about to be descended upon by a swarm of Bugs.
-->'''Tor''': Come on, you bastards! What are you waiting for?
-->'''Brick''': Shut up, fat head!
-->'''Tor''': You starting with me?
-->'''Brick''': [[BluntYes Yeah]], just like covering your six, huh?
