{{Quote|Do not let them touch you! It is said they will consume your body and mind!|[[Pavium]] warning his troops of pod infectors.{{Ref/Level|HW2|Fighting Retreat}}}}
The '''pod infector''' (sometimes shortened as '''pod'''),{{Ref/Game|Id=PLPI|HW2|Phoenix Logs|Detail=Pod Infectors}} often ubiquitously called the '''Flood infection form''',{{Ref/Book|Id=enc11p164|Enc11|Page=164}}{{Ref/Book|Id=enc22|Enc22|Page=406}} is a stage of the virulent [[Flood]] xenoform. It serves as the primary form for spreading the Flood infection due to its effectiveness compared to mere [[Flood spores]] when deployed in large numbers. Subsequently, it is usually the first Flood form to be produced as well as the most commonly encountered Flood form.{{Ref/Reuse|PLPI}}


The '''Flood infection form''' is a stage of the virulent [[The Flood|Flood]] xenoform. It is the most commonly seen stage of the Flood, and is the form responsible for spreading the Flood infection.
==Overview==
[[File:HOD-InfectionForm.jpg|thumb|200px|left|A pod infector on display at [[Outpost Discovery]].]]
===Physical characteristics===
{{Quote|As you can see, it has tentacles in place of legs, plus a couple of extremely sharp penetrators, which they use to invade the victim's central nervous system and take control of it.|[[Melissa McKay]] describing a pod infector.{{Ref/Novel|Id=McKayQuote|TF|10|Quote=As you can see, it has tentacles in place of legs, plus a couple of extremely sharp penetrators, which they use to invade the victim's central nervous system and take control of it.}}}}
Pod infectors have soft, pod-shaped bodies; they are characterized by a small, sagging brown lobe rising from the top of its back,{{Ref/Reuse|enc11p164}} while its frontal surface has numerous tentacle-like appendages and a frond-like array, which acts as the creature's sensory system.{{Ref/Game|Id=PLIF|HW2|Phoenix Logs|Detail=Infection Forms}}{{Ref/Reuse|enc22}} Their tendrils are multi-purpose locomotion systems and insidious methods of control.{{Ref/Reuse|PLIF}}{{Ref/Reuse|enc22}} Used for attacking and infecting organisms,{{Ref/Book|Id=enc11p180|Enc11|Page=180}} each tendril ends in nano-scale barbs, which can latch onto a target's body, slice open bare skin,{{Ref/Novel|TF|12|Quote=The Spartan gave a cry of pain, felt the tentacle slide down toward his spine, and knew it was over.}} and even cut through armor or environmental suits.{{Ref/Reuse|PLIF}}{{Ref/Reuse|enc22}} The pod infector's bulbous body is filled with noxious gases,{{Ref/Reuse|enc22}} while its numerous tentacles allow them to travel at high rates of speed and leap surprising distances in pursuit of a host.{{Ref/Reuse|Library}}{{Ref/Book|Id=OSFM|OSFM|Page=174}}


==Description==
The pod infector does not feel pain or fear.{{Ref/Reuse|enc22p408}} Though barely intelligent on their own, once a pod infector infiltrates a sentient creature, they turn the victim's cognitive power to the furtherance of Flood goals. Each pod infector able to sift through memories of any sentient creature to learn of military countermeasures, security access codes, and the location of population centers. This information is then shared with other Flood through their connection with the [[key mind]]s.{{Ref/Reuse|PLIF}}
The Flood infection form might appear at first glance to be little more than a harmless and repulsive creature, but once it gains physical contact with a biological host, it becomes an instantly deadly foe. Small tentacles underneath its body penetrate the skin, tap into the victim's spinal cord, and unleash an attack on the host's nervous system via direct contact with the spine, killing the host almost instantly. Once this is accomplished, it rewrites the neural pathways of the victim's brain with its tendrils, forcing a resonant frequency match between its neural signals and the host's.
{{clear}}
===Function===
{{Quote|You can see how the body has been transformed by the genetic restructuring of the Flood infection. The small creatures carry spores that cause a host to mutate. The mutated host then produces spores that can pass the Flood to others. It is insidious and elegant. As long as any hosts remain, the Flood is virulent.|[[343 Guilty Spark]] explains the infection process.{{Ref/Level|Id=343GSquote|HCE|The Library|Quote=You can see how the body has been transformed by the genetic restructuring of the Flood infection. The small creatures carry spores that cause a host to mutate. The mutated host then produces spores that can pass the Flood to others. It is insidious and elegant. As long as any hosts remain, the Flood is virulent.}}}}


Encapsulated [[LF.Xx.3273 Flood Super Cell|Flood Super Cells]] are then released into the host organism, transforming into full-functioning Flood cells. These cells interface with the host's cells, analyze their genetic code, and then digest them, overtaking the victim's biomass at rapid, chain-reaction speeds. This process leads to the host being overtaken by the Flood infection, allowing the infection form to use the host corpse as it sees fit, because of the horrific thought of this happening to a host it is evident that most [[Human]]s would rather commit suicide than going through the pain of infection.  
Pod infectors appear to be developed from [[Flood tadpole|a form]] vaguely resembling a larva or tadpole but bearing the basic superficial characteristics of a pod infector.{{Ref/Site|Id=onefinaleffort|URL=http://halo.bungie.net/news/content.aspx?type=topnews&cid=25650|Site=Bungie.net|Page=One Final Effort (4/16/2010)|D=11|M=4|Y=2013}} Once the parasite can establish a hive, it can begin to produce massive numbers of infection forms that spread out in search of new sentients to infect, and non-sapient animals on which to feed; pod infectors serve as the most basic and common type of infection forms. Both ground and airborne infection forms are used as living weapons, hurling themselves at the enemy to overwhelm defenses and assimilate the unprepared.{{Ref/Reuse|enc22}} The [[Flood blister]] itself is an infection form, incubating spores as well as carrying pod infectors; when ruptured, the blister releases the pod infectors.{{Ref/Level|H3|Cortana (level)|Cortana}}{{Ref/Book|Enc22|Page=407}} [[Flood carrier form|Carrier forms]] serve as mobile incubators of pod infectors; when they are in close range of enemies, or when their sacs are perforated, they rapidly swell and then detonate,{{Ref/Reuse|enc11p165}} releasing pod infectors being held within.{{Ref/Book|Enc22|Page=409}} [[Flood pure form]]s, including the [[Flood spawner form|spawner form]] and the [[tank form]], can gestate pod infectors to spread the Flood infection.{{Ref/Book|Id=enc11p166|Enc11|Page=166}}{{Ref/Game|HW2|Phoenix Logs|Detail=Spawners}}


After this is accomplished, the infection form burrows into the host body, moving aside the internal organs and taking up residence within the chest cavity. In order to facilitate further use of the infected organism, the Flood infection consumes the host's biomass as fuel for further sustenance and as material for further modifications of the infected life form. Common examples of these include the partially-transformed state of a combat form, whose body is host to Flood-generated structures, and the creation of a carrier form, which serves as a mobile, explosive incubator for more infection forms.  
[[File:TFS-Likeafrog.png|thumb|250px|A carrier form spawning pod infectors aboard the {{UNSCShip|Spirit of Fire}} in 2537.]]
Serving as the primary vector for the Flood infection, pod infectors usually attack en masse, overwhelming and overpowering their prey, until one is able to burrow into the victim's flesh,{{Ref/Reuse|Library}} As with other infection forms, the pod infector has an array of "penetrators", which are barbed tentacles that can cut through flesh and armor.{{Ref/Reuse|PLIF}}{{Ref/Reuse|enc22}} [[Energy shielding]] destroys pod infectors on contact, causing them to explode in a small burst of gas and flesh.{{Ref/Game|Id=HCE|HCE|gameplay}}{{Ref/Game|Id=H2|H2|gameplay}}{{Ref/Game|Id=H3|H3|gameplay}} When a pod infector attacks a victim, its tentacles insert into the spine,{{Ref/Novel|TF|6|Quote=There was a cry of pain as something landed on Private Riley’s back, drove a needlelike penetrator through his skin, and aimed it down toward his spine.}}{{Ref/Novel|TF|9|Quote=...because ever since the infection form had inserted its penetrator into his spine, Private Wallace A. Jenkins had been sharing his physical form with something he thought of as "the other."}} with the goal of invading the target's central nervous system,{{Ref/Reuse|McKayQuote}} which then initiates a violent transformation triggered by the the [[Flood spore]]s carried by the pod infector.{{Ref/Reuse|343GSquote}} Once the target is compromised, the pod infector injects [[Flood Super Cell]]s to suborn the victim's nervous system,{{Ref/Reuse|enc22}} "digesting" the DNA of its victims,{{Ref/Book|AoH3|Page=26}} while the pod infector itself bores into the host body to hollow out a nest, quickly twisting the remains of its victim into a combat or carrier form.{{Ref/Reuse|enc22}}


In exceedingly rare cases, such as if the infection form has been damaged or is incredibly old, it will go through this process ''without'' killing the host, leaving them at least partially aware of what is going on, but unable to move or act. This was the fate of UNSC Private [[Wallace A. Jenkins]] during the raid on the "[[Covenant Empire|Covenant]] weapons cache" on [[Installation 04]].<ref>''[[Halo: The Flood]]'', page 176</ref> This aged version of the infection form must have been kept in captivity for far too long, thereby reducing its potential of complete transformation of its host into a [[The Flood|Flood]] [[Flood combat form|Combat Form]]. Jenkins survived infection, and even remained conscious, with short periods of time where he could exert control over his mutated body.  
Due to the balloon-like qualities of the pod infector, it could deflate itself to fit inside the victim's body.{{Ref/Novel|TF|10|Quote=If you peek through the hole in her chest you can see the remains of the infection form that deflated itself enough to fit in around her heart and lungs.}} Even if the pod infector is quickly removed, Flood cells in the wounds will slowly consume the victim and turn them into quivering, spore-packed blisters.{{Ref/Reuse|PLIF}}{{Ref/Anthology|Id=TML|Evo|Story=The Mona Lisa}} The Flood utilizes the hosts' nervous system and calcium store to mutate its body;{{Ref/Book|AoH|Page=50}} if the infected host has sufficient biomass for self-sustenance, it will mutate neurologically and physiologically into a [[Flood combat form|combat form]].{{Ref/Book|Id=enc11p165|Enc11|Page=165}} The pod infector is capable of augmenting its new body and repair minor damage;{{Ref/Book|Id=enc22p408|Enc22|Page=408}} as such, combat forms typically possess unnatural physical strength, perhaps gained through the mutation of the host's musculoskeletal structures.{{Ref/Reuse|enc11p165}} Otherwise, sections of the host's body are consumed and converted into FSC, with much of their internal organs being consumed and replaced with FSC accretions that function as support lattices. Some limbs and sensory organs are retained on the combat form to enable use of tools, weapons, or vehicles; though the pod infector sees the environment using its own sensory organs—often the flexible fronds or antennae on the end of narrow tendrils—while whatever remains of the host's native senses are usually redundant and ignored. Combat forms also tend to retain some of its host's characteristics; sapient hosts are generally made into the most basic version of combat form, simply known as an [[attacker form]],{{Ref/Reuse|enc22p408}} whereas non-sapient hosts are made into [[Flood thrasher form|thrasher]] or [[Flood swarm form|swarm]] forms.{{Ref/Book|Id=enc22p409|Enc22|Page=409}} [[Human]] attacker forms are notably known for their agility and swift movement rather than the heavy and dense frame of the their [[Sangheili]] counterparts.{{Ref/Game|HCEA|Library (feature)|Detail=Human Combat Form}} If its host has been heavily damaged, a pod infector may abandon its host to look for a new one. Conversely, if the pod infector inside an attacker form has been destroyed, but the attacker form itself is intact enough to continue serving its purpose, a loose pod infector may burrow inside the body and replace the one that mutated it, effectively "re-animating" the attacker form.{{Ref/Reuse|H3}}


An infection form may abandon its host if the corpse has been heavily damaged, and look for a new one. If the infection form inside a combat form has been destroyed, but the combat form itself is intact enough to continue serving its purpose, loose infection forms may burrow inside the body and take the place of the one that mutated it, effectively "re-animating" the combat form. Infection forms appear at first glance to be quite small, but if compared with the size of an average [[human]], their true size is revealed, comparable to the size of an average human upper torso.
In some circumstance, the pod infector is unable to completely dominate the original personality and the victim remains fully aware of their irrevocable transformation and their being used as a tool of the Flood. Though their bodies are bent to the Flood's will, occasionally the victim can still whisper for mercy or cry out in pain. More often, the parasite will speak on their behalf, using stolen thoughts and memories as a psychological weapon, terrorizing both the host and anyone unfortunate enough to be within earshot.{{Ref/Reuse|enc22p408}}{{Ref/Game|HW2|Phoenix Logs|Detail=Infected}} This was the fate of [[Wallace Jenkins]] during the [[Battle of Installation 04|Battle]] of [[Installation 04]]; a pod infector had been severely weakened during long periods of hibernation, and while strong enough to take over and transform Jenkins' body, it lacked the force and clarity to completely control Jenkins.{{Ref/Novel|TF|6|Quote=Due to some fluke, some random toss of the galactic dice, the mind that invaded his body had been severely weakened during the long period of hibernation, and while strong enough to take over and begin the work necessary to create a combat form, it lacked the force and clarity required to completely dominate its host the way it was supposed to.}} With the Flood mind weakened, Jenkins survived infection, and even remained conscious, with short periods of time where he could exert control over his mutated body.{{Ref/Novel|TF|10|Quote=Jenkins had used pantomime to request a mirror. A well-meaning Corporal brought one in, held it up in front of the soldier's devastated face, and was frightened when he tried to scream.}}{{Ref/Novel|TF|12|Quote=Jenkins, still unable to speak, managed to mouth the words “thank you.”}}


While infection forms are essential in early stages of infecting a population, they are by no means the only way the Flood can facilitate infection. It appears that merely introducing any Flood biomatter into the body of a host will begin the infection process. However, it seems no other method of infection is able to instantaneously kill and transform a host like an infection form can.<ref>'''[[Halo: Evolutions - Essential Tales of the Halo Universe]]''' - ''[[The Mona Lisa]]''</ref>
While an effective vector of infection against armored and shielded organisms—including those equipped with atmospheric filters—a pod infector is not necessary for the Flood to infect a host; merely ingesting Flood spores or inserting them via a wound is sufficient to initiate Flood conversion—in two notable instances, Flood spores were introduced into the body through a bite wound. Such infection may occur several seconds or perhaps minutes later, yet the transformation will occur almost instantaneously once it has begun.{{Ref/Level|HW|Anders' Signal}}{{Ref/Reuse|TML}}
===Immunities and defenses===
[[Energy shielding]] negates the effect of the infection form by causing it to explode on contact in a small, damaging cloud of gas. However, if no shield system is present on the target, the infection process begins.
 
At this time, the only known [[human]] to be incompatible with Flood infection forms is [[Staff Sergeant]] [[Avery Junior Johnson|Avery Johnson]] due to his supposed contracting of [[Boren's Syndrome]] from the residual radiation of a crate full of [[Type-1 Antipersonnel Grenade|plasma grenades]] on [[Paris IV]]. However, Johnson actually contracted this immunity from the augmentations he received as part of the [[ORION Project]]. According to [[Cortana]]'s analysis of various Flood forms, [[Kig-yar]] and [[Unggoy]] generally lack the necessary calcium stores and biomass to be converted into combat forms and are instead used as biomass stores and as carrier forms,<ref>''''[[Halo: The Flood]]'''', page ???</ref> although Kig-yar and Unggoy combat forms have been observed during [[Battle of the Flood-controlled Shield World|one engagement]].<ref>'''''Halo Wars'''''</ref>
 
The [[Mgalekgolo]]'s lack of a central nervous system and nature as an invertebrate colony consisting of multiple worms likely make them immune to Flood infection.<ref>'''''[[Halo: First Strike]]'''''</ref> The invertebrate nature of the [[Yanme'e]], along with their hard, chitinous exoskeleton, would seem to make them immune as well.
 
== Combat ==
Infection forms will gather in large swarms, attacking with their claws and tentacles. If the victim's shields are active, as explained earlier, the infection form will burst. However, the sheer force of numbers can sometimes deplete a victim's shields, allowing these Flood forms to take control of the Human/Brute/Elite body.
 
A single round from any weapon will burst an infection form. For this reason, automatic weapons are recommended. [[Dual wielding|Dual-wielding]] [[Type-25 Directed Energy Rifle|Plasma Rifles]], [[Type-25 Directed Energy Rifle/Jiralhanae variant|Brute Plasma Rifles]], [[Type-25 Carbine|Spikers]], or using a UNSC ballistic weapon all work well. The Battle Rifle, with its bursts of fire, can be quite effective, the [[Shotgun]] works well too when shooting at large groups closing in. Try to avoid using weapons such as [[M6 Series|M6 Handguns]], or [[Type-25 Directed Energy Pistol|Plasma Pistols]], as their rate of fire is very low. Also, try to avoid using [[Grenade]]s, as they close in extremely quickly and you may suffer damage from your own grenade. In ''[[Halo: Combat Evolved]]'', automatic weapons like the Assault Rifle and Plasma Rifle are good on them, the Needler in many ways can also be good as the needles have homing ability: be careful though, do not stick too many Needles on one at a time while they are close as if you do it will explode and effect you most likely depleting your shields. SMGs are incredibly effective for taking on swarms of infection forms with its large magazine size and impressive rate of fire. The Sentinel Beam is also extremely effective and can swiftly obliterate entire swarms of infection forms at long ranged distances.
 
Infection forms are spawned from bulging, sac-like pods in [[Flood hive|Flood Hives]], called the [[Flood growth pod|Flood Growth Pods]]. It may be tempting to destroy these sacs, but it is actually more advisable not to, since destroying them will not kill the infection forms inside.


==Trivia==
==Trivia==
[[File:Infectionforms Halo1.jpg|thumb|Master Chief watches as infection forms prepare to consume a dead [[Elite]], and a dead [[Unggoy|Grunt]].]]
*[[Robert McLees]]'s design of the pod infector was inspired by a scene in the children's book ''The Saggy Baggy Elephant'', in which a palm tree was launched into the air by dancing elephants; the illustration formed a shape that became the basis of the pod infector.{{Ref/Site|Id=rollingstone|URL=https://www.rollingstone.com/culture/rs-gaming/halo-2-bungie-development-1235157887/|Site=Rolling Stone|Page=‘Halo 2’ Is a Classic, But Its Development Was a Mess|D=10|M=11|Y=2024}}
*Infection forms are carried and incubated by [[Flood carrier form|Carrier Forms]] and from [[Flood growth pod|Flood Growth Pods]] in [[The Flood|Flood]]-infested areas. Try not to destroy these sacs, unless you think you can take them one by one, or swarm by swarm.
*In ''[[Halo: Combat Evolved]]'', if a pod infector latches itself onto a Marine or one of the Covenant, instead of mutating the host, it will become irrevocably attached until the host is dead. If at least one pod infector manages to leap onto an unshielded player in this game, it will deal a noticeable amount of damage (this will increase depending on difficulty and number of pod infectors attached), fall off, and attempt to strike the player again. This effect on the player also appears in ''Halo 3''.
*In ''Halo: The Flood'', infection forms are mistakenly referred to as being colored white.<ref>''[[Halo: The Flood]]'' page 174</ref>
*In ''Halo: Combat Evolved'', pod infectors are not affected by fall damage, most likely due to the script or slow speed during freefall.
* In [[Halo: Combat Evolved]], if an infection form latches itself onto a Marine or one of the Covenant, instead of mutating the host, it will become irrevocably attached until the host is dead.  
*An [[energy sword]] will not lose energy by killing pod infectors in ''Halo 2'' and ''Halo 3'', but this method is highly ineffective as pod infectors are extremely hard to hit with an energy sword.
*An [[Type-1 Energy Weapon/Sword|Energy Sword]] will not lose energy by killing infection forms in ''[[Halo 2]]'' and ''[[Halo 3]]'', but this method is highly ineffective as infection forms are extremely hard to hit with an Energy Sword.
*Pod infectors do not add points to the player's meta-score when the [[campaign scoring]] is activated in ''Halo 3'' and ''[[Halo: The Master Chief Collection]]''. This is most likely because pod infectors come in swarms, and could be used to rack up points with almost no effort.
*The [[Flood tank form|Tank Form]] has the ability to spit out infection forms. This is demonstrated during ''Halo 3'' for the Tank Form and ''Halo 2'' for Gravemind.
*Unlike in ''Halo: Combat Evolved'' and ''Halo 2'', the pod infectors in ''Halo 3'' float in water. Thus, they cannot infect corpses that are in water ponds because of this animation.
*Infection forms do not add points to your meta-score when the [[Campaign]] Scoring is activated in ''Halo 3''. This is most likely because infection forms come in swarms, and could be used to rack up points with almost no effort.
*A [[Cut Halo 3 enemies#Flood|cut enemy]] intended to be included in ''Halo 3'' was the <code>flood_infection_banger</code>, a variant of pod infector which would explode like a plasma grenade when destroyed.{{Ref/YouTube|R60geSLtnWk|Lord Zedd|Halo 3 - Cut Enemy: Flood Infection "Banger"}}
*Infection forms operate in a similar fashion to the chestbuster Xenomorph (being inside a host's chest) and the facehugger Xenomorph of the ''Alien'' franchise, the ''Borg Nanoprobes'' of the ''Star Trek'' franchise, the ''Headcrabs'' from the ''Half-Life'' series, and ''the Thing'' from the John Carpenter film of the same name.
* In ''Halo Wars'', when Sergeant Forge shoots the pod infectors that were attacking Professor Anders, they do not pop like pod infectors usually do in other appearances. Instead, they simply fall lifelessly to the ground. Similarly, in ''[[Halo Wars 2: Awakening the Nightmare]]'', a spike round pinned a pod infector into the wall.
*The infection forms in ''Halo 3'' float in water. Thus, they cannot infect corpses that are in water ponds because of this animation. (E.g. on the level [[Halo (Halo 3 level)|Halo]] it will appear different close up then it will farther away.) However, in ''Halo: Combat Evolved'', they sink.
*In the book ''Halo: The Flood'', an infection form almost infected [[John-117]] when he turned his back, due to his energy shields being drained.
*According to the book, ''Halo: The Flood'', the infection forms make a "meep" sound. This can be heard in the games, although it sounds more like an ominous droning.
*In ''[[Halo: Combat Evolved]]'', if you shoot one infection form in a swarm, it will pop and cause a chain reaction causing all the other infection forms to pop with it in the swarm. This was less effective in ''Halo 2'', but returned in ''Halo 3'' (although not as powerful as in ''Halo: Combat Evolved'').
*Several can be seen within the Flood Observation chamber on the ''Halo 3'' [[Multiplayer]] map [[Cold Storage]]. These Flood make [[Cold Storage]] the 6th multiplayer map with [[Non-playable character|NPC]] enemies (Along with [[Construct]], [[Guardian (level)|Guardian]], [[Last Resort]], [[Epitaph]] and [[Isolation]] which have [[Sentinel]]s, [[Constructor]]s, seagulls or pterodactyl-like birds flying around). However, you cannot get to them.
*In ''Halo: Combat Evolved'', the infection forms have a pulsating glow in the dark.
*The infection form was featured in ''Halo Wars'' as a non-playable unit for the Flood. They have the ability to crawl over walls, being able to reach ground no other forces can reach and transform most infantry into Combat Forms.
*On the ''Halo 3'' level Halo, when in the [[M12 Force Application Vehicle|Warthog]], [[M274 Ultra-Light All-Terrain Vehicle|Mongoose]], [[Type-25 Rapid Assault Vehicle|Chopper]], etc., if you drive into the infection forms you simply drive over them, possibly flipping your vehicle. Performing this action kills all other Flood forms including the carrier forms, although the latter explode violently on contact.
*In ''Halo: Combat Evolved'', if players listen close enough to the droning sounds emitted by the Infection Forms, it can be noted that the sounds are actually the same sounds used for "Pfhor Fighters" death screams and occasional random chattering from the [[Marathon]] franchise. However, the sounds have a slightly higher pitch, as well as oozing sounds, which make the reuse of the sound effect from Marathon almost completely unnoticeable.
*In ''Halo 3'', despite their seemingly weak form, they can actually move certain objects that are bigger than they are. This can be observed in the crashed ship on the ''Halo 3'' level Floodgate and in the level Cortana.
*In ''Halo: Combat Evolved'' it is possible to "stick" an infection form with a plasma grenade.
* In ''Halo Wars'', when Sergeant Forge shoots the Flood infection forms that are attacking Professor Anders, they do not pop like all other infection forms. Instead, they simply fall lifelessly to the ground.
*In [[Halo PC]], if the player uses cheat_bump_possession to take over a Marine or a Grunt, they will have no control over their body if an infection form latches onto them.

"Do not let them touch you! It is said they will consume your body and mind!"
— Pavium warning his troops of pod infectors.[2]

The pod infector (sometimes shortened as pod),[3] often ubiquitously called the Flood infection form,[4][5] is a stage of the virulent Flood xenoform. It serves as the primary form for spreading the Flood infection due to its effectiveness compared to mere Flood spores when deployed in large numbers. Subsequently, it is usually the first Flood form to be produced as well as the most commonly encountered Flood form.[3]

Overview[edit]

Physical characteristics[edit]

"As you can see, it has tentacles in place of legs, plus a couple of extremely sharp penetrators, which they use to invade the victim's central nervous system and take control of it."
— Melissa McKay describing a pod infector.[6]

Pod infectors have soft, pod-shaped bodies; they are characterized by a small, sagging brown lobe rising from the top of its back,[4] while its frontal surface has numerous tentacle-like appendages and a frond-like array, which acts as the creature's sensory system.[7][5] Their tendrils are multi-purpose locomotion systems and insidious methods of control.[7][5] Used for attacking and infecting organisms,[8] each tendril ends in nano-scale barbs, which can latch onto a target's body, slice open bare skin,[9] and even cut through armor or environmental suits.[7][5] The pod infector's bulbous body is filled with noxious gases,[5] while its numerous tentacles allow them to travel at high rates of speed and leap surprising distances in pursuit of a host.[1][10]

The pod infector does not feel pain or fear.[11] Though barely intelligent on their own, once a pod infector infiltrates a sentient creature, they turn the victim's cognitive power to the furtherance of Flood goals. Each pod infector able to sift through memories of any sentient creature to learn of military countermeasures, security access codes, and the location of population centers. This information is then shared with other Flood through their connection with the key minds.[7]

Function[edit]

"You can see how the body has been transformed by the genetic restructuring of the Flood infection. The small creatures carry spores that cause a host to mutate. The mutated host then produces spores that can pass the Flood to others. It is insidious and elegant. As long as any hosts remain, the Flood is virulent."
— 343 Guilty Spark explains the infection process.[12]

Pod infectors appear to be developed from a form vaguely resembling a larva or tadpole but bearing the basic superficial characteristics of a pod infector.[13] Once the parasite can establish a hive, it can begin to produce massive numbers of infection forms that spread out in search of new sentients to infect, and non-sapient animals on which to feed; pod infectors serve as the most basic and common type of infection forms. Both ground and airborne infection forms are used as living weapons, hurling themselves at the enemy to overwhelm defenses and assimilate the unprepared.[5] The Flood blister itself is an infection form, incubating spores as well as carrying pod infectors; when ruptured, the blister releases the pod infectors.[14][15] Carrier forms serve as mobile incubators of pod infectors; when they are in close range of enemies, or when their sacs are perforated, they rapidly swell and then detonate,[16] releasing pod infectors being held within.[17] Flood pure forms, including the spawner form and the tank form, can gestate pod infectors to spread the Flood infection.[18][19]

Serving as the primary vector for the Flood infection, pod infectors usually attack en masse, overwhelming and overpowering their prey, until one is able to burrow into the victim's flesh,[1] As with other infection forms, the pod infector has an array of "penetrators", which are barbed tentacles that can cut through flesh and armor.[7][5] Energy shielding destroys pod infectors on contact, causing them to explode in a small burst of gas and flesh.[20][21][22] When a pod infector attacks a victim, its tentacles insert into the spine,[23][24] with the goal of invading the target's central nervous system,[6] which then initiates a violent transformation triggered by the the Flood spores carried by the pod infector.[12] Once the target is compromised, the pod infector injects Flood Super Cells to suborn the victim's nervous system,[5] "digesting" the DNA of its victims,[25] while the pod infector itself bores into the host body to hollow out a nest, quickly twisting the remains of its victim into a combat or carrier form.[5]

Due to the balloon-like qualities of the pod infector, it could deflate itself to fit inside the victim's body.[26] Even if the pod infector is quickly removed, Flood cells in the wounds will slowly consume the victim and turn them into quivering, spore-packed blisters.[7][27] The Flood utilizes the hosts' nervous system and calcium store to mutate its body;[28] if the infected host has sufficient biomass for self-sustenance, it will mutate neurologically and physiologically into a combat form.[16] The pod infector is capable of augmenting its new body and repair minor damage;[11] as such, combat forms typically possess unnatural physical strength, perhaps gained through the mutation of the host's musculoskeletal structures.[16] Otherwise, sections of the host's body are consumed and converted into FSC, with much of their internal organs being consumed and replaced with FSC accretions that function as support lattices. Some limbs and sensory organs are retained on the combat form to enable use of tools, weapons, or vehicles; though the pod infector sees the environment using its own sensory organs—often the flexible fronds or antennae on the end of narrow tendrils—while whatever remains of the host's native senses are usually redundant and ignored. Combat forms also tend to retain some of its host's characteristics; sapient hosts are generally made into the most basic version of combat form, simply known as an attacker form,[11] whereas non-sapient hosts are made into thrasher or swarm forms.[29] Human attacker forms are notably known for their agility and swift movement rather than the heavy and dense frame of the their Sangheili counterparts.[30] If its host has been heavily damaged, a pod infector may abandon its host to look for a new one. Conversely, if the pod infector inside an attacker form has been destroyed, but the attacker form itself is intact enough to continue serving its purpose, a loose pod infector may burrow inside the body and replace the one that mutated it, effectively "re-animating" the attacker form.[22]

In some circumstance, the pod infector is unable to completely dominate the original personality and the victim remains fully aware of their irrevocable transformation and their being used as a tool of the Flood. Though their bodies are bent to the Flood's will, occasionally the victim can still whisper for mercy or cry out in pain. More often, the parasite will speak on their behalf, using stolen thoughts and memories as a psychological weapon, terrorizing both the host and anyone unfortunate enough to be within earshot.[11][31] This was the fate of Wallace Jenkins during the Battle of Installation 04; a pod infector had been severely weakened during long periods of hibernation, and while strong enough to take over and transform Jenkins' body, it lacked the force and clarity to completely control Jenkins.[32] With the Flood mind weakened, Jenkins survived infection, and even remained conscious, with short periods of time where he could exert control over his mutated body.[33][34]

While an effective vector of infection against armored and shielded organisms—including those equipped with atmospheric filters—a pod infector is not necessary for the Flood to infect a host; merely ingesting Flood spores or inserting them via a wound is sufficient to initiate Flood conversion—in two notable instances, Flood spores were introduced into the body through a bite wound. Such infection may occur several seconds or perhaps minutes later, yet the transformation will occur almost instantaneously once it has begun.[35][27]

Trivia[edit]

  • Robert McLees's design of the pod infector was inspired by a scene in the children's book The Saggy Baggy Elephant, in which a palm tree was launched into the air by dancing elephants; the illustration formed a shape that became the basis of the pod infector.[36]
  • In Halo: Combat Evolved, if a pod infector latches itself onto a Marine or one of the Covenant, instead of mutating the host, it will become irrevocably attached until the host is dead. If at least one pod infector manages to leap onto an unshielded player in this game, it will deal a noticeable amount of damage (this will increase depending on difficulty and number of pod infectors attached), fall off, and attempt to strike the player again. This effect on the player also appears in Halo 3.
  • In Halo: Combat Evolved, pod infectors are not affected by fall damage, most likely due to the script or slow speed during freefall.
  • An energy sword will not lose energy by killing pod infectors in Halo 2 and Halo 3, but this method is highly ineffective as pod infectors are extremely hard to hit with an energy sword.
  • Pod infectors do not add points to the player's meta-score when the campaign scoring is activated in Halo 3 and Halo: The Master Chief Collection. This is most likely because pod infectors come in swarms, and could be used to rack up points with almost no effort.
  • Unlike in Halo: Combat Evolved and Halo 2, the pod infectors in Halo 3 float in water. Thus, they cannot infect corpses that are in water ponds because of this animation.
  • A cut enemy intended to be included in Halo 3 was the flood_infection_banger, a variant of pod infector which would explode like a plasma grenade when destroyed.[37]
  • In Halo Wars, when Sergeant Forge shoots the pod infectors that were attacking Professor Anders, they do not pop like pod infectors usually do in other appearances. Instead, they simply fall lifelessly to the ground. Similarly, in Halo Wars 2: Awakening the Nightmare, a spike round pinned a pod infector into the wall.
