A '''Flood combat form'''<ref>'''[[Halo: The Flood]]''', ''page 225'' (''"The first of these '''combat forms''' he'd seen had once been Elites."'')</ref> is the product of [[Flood Super Cell]]s, typically via a [[Pod infector]], infecting a [[Sentience|sentient]] host organism. They serve as the Flood's primary combatants, defending the Flood against attack and securing additional hosts for infection.

A '''Flood combat form''' is the primary combat form of the [[Flood]] parasite, and one of the most common forms found in [[Feral Stage|early stages]] of a Flood outbreak. Combat forms consist of infected [[Sentience|sentient]] hosts infected via means of the [[Flood Super Cell]], typically by a [[pod infector]]. They serve as the Flood's primary combatants, defending the Flood against attack and securing additional hosts for infection.


==Pathology==
==Pathology==
When a Pod infector successfully enters a host body, it takes over the organism's nervous system and mutates its body using [[LF.Xx.3273 Flood Super Cell|Flood Super Cells]];<ref name="bestiarum">'''[[Bestiarum]]'''</ref> inhalation of [[Flood spore|spores]] can have the same effect. During the infection process, the host's internal organs are broken down, and the resultant nutrient stockpile is used to develop the tentacles, claws and various other appendages and apparatuses. Combat forms can spread the Super Cell merely through wounding a victim, though such infection may progress gradually.<ref>'''Halo: Evolutions - Essential Tales of the Halo Universe''' - ''The Mona Lisa''</ref> If the combat form is infected by a Pod infector, it maintains the infector's red sensory appendages as an impromptu central nervous system until the host has been completely assimilated.<ref name="wp flood">[https://www.halowaypoint.com/en-us/universe/species/flood '''Halo Waypoint''': ''Flood'']</ref>
===Infection and creation===
Combat forms are typically created when a [[pod infector]] is successfully able to enter a host's body, though this is not the only vector by which hosts can be infected.{{Ref/Site|Id=Universe|URL=https://www.halowaypoint.com/en-us/universe/species/flood|SiteName=Halo Waypoint|PageName=Flood}} Flood outbreaks can often be caused by [[Flood spore|spores]] or other microbiological vectors entering the host body{{Ref/Reuse|Universe}}, or by contact with other forms such as (but not limited to) a Flood [[Seeder infector|Seeder]] or [[Flood infester form|Infester]].{{Ref/Game|Id=ATN|HW2|Detail=[[Halo Wars 2: Awakening the Nightmare|Awakening the Nightmare]]}} In more advanced stages of infection, the need for specific [[infection form]]s is decreased as the Flood-infected area converts to a [[Blightlands|Blightland]] or [[Flood hive]] - by which point, the Flood presence makes up the majority of the terrain in the area, making contact with the Flood Super Cell and the naturally-generated spores an inevitability. Some Flood structures such as the "[[Flood launcher|launcher]]" specialising in shooting clouds of Spores at uninfected forces, causing them to succumb to the infection without any kind of infection form involved.{{Ref/Game|HW|Flood Launcher in-game unit}}


Both living and deceased hosts can be infected, although the infection process is inherently fatal to living hosts. If the host is still living when initially infected, or at the very least has not suffered somatic brain cell death, the Flood is able to retrieve comparatively vast quantities of information from the host's memory, ranging from muscle memory to specific coordinates, access codes, flight protocols, etc.<ref>'''[[Halo Graphic Novel]]''', ''[[The Last Voyage of the Infinite Succor]]''</ref> Once it has total control over the host's corpse, the Pod infector changes the physiology of the body to better suit its own needs. As combat forms retain most of the host's abilities they are able to utilize their host's weapons and vehicles, albeit with less finesse.
As Flood forms, including the combat form, naturally produce the Flood Super Cell (FSC), even being in contact with one can result in infection for an unprotected potential host. Given the combat forms' preference for melee combat, this makes even non-fatal strikes a death sentence, though such infections may progress slowly.{{Ref/Anthology|Id=MonaLisa|Evo|[[The Mona Lisa]]}} However, infection by spore inhalation or infection form is extremely quick, with a host succumbing often in as little as a few seconds.


On rare occasions, weak or damaged Pod infectors cannot properly take over a host, allowing the host to survive, even retaining some control and consciousness, as in the case of [[Private First Class]] [[Wallace A. Jenkins|Wallace Jenkins]].<ref>'''[[Halo: The Flood]]''', ''pages 171-176, 273-276''</ref>
When conventionally infected by a pod infector, the infector latches onto the host and dig into the host's flesh with a razor-sharp barb-like appendage, injecting the FSC and proceeding to burrow themselves within the host. Typically, the pod infector makes its home within the chest cavity of the host life form, though depending on circumstance this is not always the case. Depending on the host in question, the pod infector will dislodge the host's bones and organs to make room for itself, resulting in extreme disfiguration such as dislocating the host's jaw{{Ref/Game|Id=H2AMP|H2A|[[Infection]] game mode}} or - in the case of infected [[Sangheili]] - completely snapping the neck. This process can be performed on living or recently-deceased hosts, though often results in the "death" of a living host prior to their re-animation once the FSC takes hold.{{Ref/Reuse|Universe}} Some hosts may be attacked and infected by multiple pod infectors.{{Ref/Reuse|Flood10}} Even if the infection form is removed, the injection of FSC into the generated wounds results in those wounds becoming spore-filled blisters, and cannot save the host from infection.{{Ref/Game|Id=PLInfectionForm|HW2|[[Phoenix Logs]] - Infection Forms}}


In the initial stage of a Flood outbreak, the [[Feral Stage]], combat forms communicate using pheromones and have one instinctual behavior: to secure new hosts to strengthen the local [[Proto-Gravemind|controlling intelligence]]. It is to be noted that a group of Flood will occasionally go after [[Sentinel]]s if they are perceived to be the greatest threat in an area, even though Sentinels are unable to be infected by the Flood due to their inorganic nature.
Once infected, the super cell begins to consume and convert sections of the host body, creating growths and new appendages of new super cell. These growths appear randomly, and appendages produce whip-like tentacles that can be used by the combat form for striking enemies. As this process occurs, bodies take on the appearance (and smell) of decay.{{Ref/Novel|Id=Flood10|TF|Chapter=10}} Some limbs and sensory organs are preserved in the transformation, and are used for using tools, weapons and vehicles. Damage taken during fighting and infection can be repaired -and the body even augmented - by the controlling infection form, though the combat form is ultimately disposable.{{Ref/Game|Id=PLCombatForm|HW2|[[Phoenix Logs]] - Combat Forms}} The Flood Super Cell is able to arrange itself to mimic any organ needed to keep the host working.{{Ref/Game|Id=Bestiarum|H3|[[Bestiarum]]}} Even once the FSC has taken control of the victim, the controlling infection form can often be seen buried within the victim, with the infection form's red sensory appendages poking out of the flesh. Until the body is completely subsumed by super cell growth, these appendages are maintained as an impromptu central nervous system.{{Ref/Reuse|Universe}} Some, combat form super cell growths take on a more chitinous nature, akin to armour plating, helping protect the form from enemy attacks.{{Ref/Game|Id=H4|H4|[[Flood (gametype)|Flood]] gametype}}
Once a sufficient store of biomass is available the Flood enters the [[Coordinated Stage]], and begins forming [[Flood pure form|pure form]] Flood, with the combat forms being used either as defensive units or [[calcium]]/biomass reserves.


Flood infection is a rapid and efficient biological process, as it can take under a minute in certain cases.<ref>'''[[Halo 3]]'''</ref> Infected hosts are rapidly digested while being converted, which leaves the host severely ravaged and decayed, much like a corpse that had been exhumed a few weeks after its burial.<ref>'''Halo: The Flood''', ''page 220''</ref> Over time, the combat form begins to generate new Pod infectors in its back, transforming it into a [[Flood carrier form|carrier form]] once it has outlived its combat utility. In the field manual it says that an effective tactic is to shoot at the limbs or head.<ref name="wp flood"/><ref>'''[[Halo: First Strike]]''', ''page 47''</ref>
Hosts can be created from the living or recently deceased, though the infection process typically kills living hosts. Regardless, the process of infection and reanimation is extremely painful. and victims writhe in pain as the Flood takes control irrespective of if they were previously dead or not.{{Ref/Game|Id=H3Gameplay|H3|Gameplay}} The victim may still attempt to cry out from what remains of its mouth and throat even while being controlled, though it is also possible for the infection form to do so using the host's thoughts and memories as a psychological weapon.{{Ref/Game|Id=PLInfected|HW2|[[Phoenix Logs]] - Infected}} In some circumstances, a victim may remain fully aware of their present status, unable to do much but watch as their body is controlled by an outside force.{{Ref/Reuse|PLCombatForm}}
 
In the case of Private [[Wallace Jenkins]], an infection form had been weakened by eons of stasis and failed to completely take over Jenkins' body. As a result, the former-Marine was able to watch and listen as his body was driven to try and kill or infect those he once considered allies. Jenkins described the presence of the infection form controlling his body as the "other", a strange being without any thoughts and seemingly unaware that the host consciousness was still active inside its body.{{Ref/Novel|Id=Flood9|TF|Chapter=9}} Jenkins was able to retain a limited amount of motor control of his body, and was able to mime a request for a mirror while in captivity - though the infection form was also able to take back control to attack the Marines surrounding him.{{Ref/Reuse|Flood10}}
 
===Capabilities===
The infection form controlling a host body does not feel pain or fear, though the host is able to feel the physical effect of attacks rendered upon it.{{Ref/Reuse|PLCombatForm}} In extreme cases, the infection form will resort to self-mutilation of the host body if it needs to, such as breaking its own arms to use the snapped bone as an impromptu weapon. However, the pain inflicted on the host body in this instance may weaken the controlling infection form - though this may be as a result of the unique circumstances of Private Jenkins' infection and not representative of all combat forms.{{Ref/Reuse|Flood10}} However, the reanimated host is reliant on the infection form for all bodily and motor functions - shooting the infection form will "kill" the combat form, though the body can be re-reanimated if another infection form is able to reach it. As a result, a combat form can be resurrected as many times as is needed, provided the body is still intact enough to be a viable host - to properly kill a combat form, it must be dismembered or disfigured to the point at which it is no longer a suitable host body for an infection form. This can be accomplished through the use of explosive force, [[Gravitics|gravitic]] blasts such as those from a [[Type-2 gravity hammer|gravity hammer]], cutting the body up with a weapon such as an [[Type-1 energy sword|energy sword]] or [[combat knife]] or simply incinerating it with [[plasma]] or [[Incendiary weapon|incendiary]] fire.{{Ref/Reuse|H3Gameplay}}
 
Once infected, the infection form is able to absorb all of the host's knowledge and memories. As a result, combat forms are capable of operating firearms, driving vehicles, operating tools and even starships.{{Ref/Reuse|PLCombatForm}} In the case of the [[Skirmish on Infinite Succor|''Infinite Succor''{{'}}s infection]], infected warriors were able to set up patrols of the ship's corridors to guard the [[Proto-Gravemind]] growing in the ship.{{Ref/Comic|Id=Succor|HGN|Detail=[[The Last Voyage of the Infinite Succor]]}} The Flood's possession of an individual's body allows it to speak with the host's tongue.{{Ref/Reuse|PLCombatForm}}{{Ref/Reuse|Succor}}{{Ref/Level|H3|The Covenant (level)|The Covenant}} This memory-absorbtion extends critical knowledge- such as command codes or colony locations. As such, when critical personnel are infected, they are contributed to the construction of a [[Gravemind]].{{Ref/Level|Id=Keyes|HCE|Keyes}}
 
In combat, combat forms use their whip or scythe-like growths to attack their opponents in melee combat, and are capable of performing superhuman feats such as leaping large distances to cover ground. Even if a melee strike is not fatal, the imparted Flood Super Cell is enough to ensure the target's infection and death.{{Ref/Reuse|MonaLisa}} As the infection forms do not feel pain, combat forms are not affected by enemy attacks and will not stop until they are destroyed, or their enemy is killed. Ballistic weapons are notably less effective against combat forms because of this, with [[SRS99C-S2 AM sniper rifle]] rounds passing through combat forms with virtually no effect.{{Ref/Game|HCE|Gameplay}} Targeted shots against the limbs and embedded infection form are effective ways of dispatching combat forms.{{Ref/Book|OSFM|Page=172-175}}
 
===Role within the Flood===
Combat forms form the majority of the Flood's combatant forces, particularly in the [[Feral Stage]] of the parasite's development in which it has yet to acquire enough raw biomass for the creation of a [[Gravemind]] or [[Flood pure form|pure forms]]. During this stage, combat forms are not centrally controlled, and will begin to gather bodies for conversion into more Flood forms.{{Ref/Reuse|Keyes}} If a location cannot be immediately secured, multiple combat forms may merge to create the [[Flood Juggernaut|Juggernaut]] and [[Abomination]] keymind forms, able to direct local forces in the area until a permanent presence can be established.
 
When a local biosphere has been completely assimilated into the Flood, typically once the Flood has entered the [[Coordinated Stage]], combat forms cannot be created anymore due to a lack of viable hosts. Due to this, the Flood moves onto breaking down raw biomass into Flood Super Cell, thereby creating [[Flood pure form|pure forms]] of wholly Flood biomass. Once the number of pure forms reaches a sufficient equilibrium, combat forms are relegated to defensive roles or added to the hive's raw biomass/ [[calcium]] reserves.{{Ref/Reuse|Bestiarum}} Otherwise aging combat forms begin to eventually begin to spontaneously grow infection forms within a large, bulbous mass on their back. Eventually, this turns the combat form into a [[Flood carrier form|carrier form]].{{Ref/Reuse|Universe}}

==Types of combat forms==
Virtually any creature can be infected to become a combat form, but the most frequently-used hosts are [[Sangheili]], [[human]]s and [[Jiralhanae]]. [[Unggoy]] and [[Kig-Yar]] can be used as combat forms, but this is uncommon due to their weaker body structure. A small number of species are known to be immune to conversion, including the [[Mgalekgolo]]/[[Lekgolo]] (which are composed of boneless worms that do not have a central nervous system), the [[Yanme'e]], whose exoskeleton lacks the required amount of calcium which renders infection impossible, and the [[Huragok]] which is an artificial organism, and therefore believed to be immune.

Animals can also be rendered as combat form, provided they meet the Flood's requirements for conversion, though organisms which cannot be converted into combat forms may still find use as raw biomass.


All victims of the Flood's infection, regardless of their physiology, will undergo a similar mutation process. The skin decays rapidly, and changes to the color and texture of Flood biomass as the Flood Super Cells overtake the body. The host's arm bones elongate and grow into whip or claw-like appendages, which will serve as their primary melee weapon in close-combat situations. As the Pod infector now serves as the host's "brain", the head is usually forced aside, and can be severed without any effect on the combat form.<ref group="notes">In ''Halo 3'', the reanimation process can be witnessed; the host will twitch around in pain, and eventually collapse on the ground. Afterwards, the whip appendages will force itself out of the host's left arm, and the Pod infector will force itself out of the host's chest.</ref>
