The general design of the plasma pistol remains consistent across different variants; the weapon is made up of two main components: the upper component, which includes the main rear grip and a firing coil, and the lower component which doubles as the weapon's foregrip—though only humans have been observed to wield the weapon with two hands.{{Ref/Reuse|evg}} As a directed-energy weapon, the plasma pistol fires superheated plasma from its muzzle, where, when the weapon is active, the upper and lower charging poles constantly generate a surge of plasma; on certain variants, the charging poles take on a claw-like appearance.{{Ref/Game|Id=hrgameplay|HR|gameplay}}{{Ref/Game|Id=h4gameplay|H4|gameplay}} The charging poles tend to emit a deep green glow; even at the lowest setting, the firearm is an effective source of light.{{Ref/Novel|CH|Chapter=18}} The top of the weapon contains the upper firing coil; the coil is covered by a hatch, which opens as a venting port,{{Ref/Reuse|osfm}} as it lifts and exposes the internal components when the weapon overheats, either from repeatedly firing at its semi-automatic bolts or after discharging a scaled burst.{{Ref/Book|Id=h4evg|H4EVG|Page=84}} The rear grip features the holographic charge display—a circular progress bar that indicates the weapon charge as it is fired—the display indicates when the weapon is about to overheat from its semi-automatic bursts, or when the weapon is fully charged for a scaled burst.{{Ref/Game|Id=hcegameplay|HCE|gameplay}}{{Ref/Game|Id=h2gameplay|H2|gameplay}}{{Ref/Game|Id=h3gameplay|H3|gameplay}} There is a small button on the left side of the weapon; this exposes the upper firing coil and allows access to the weapon's internal components.{{Ref/Game|HI|plasma pistol idle animation}} Certain variants of the plasma pistol also feature a tracking sight.{{Ref/Reuse|h4evg}}

The plasma pistol is powered by a battery cell. This battery can be recharged using a variety of power sources,{{Ref/Note|While the ''Halo Encyclopedia (2009 edition)'' and the ''Halo Encyclopedia (2011 edition)'' both state that the plasma pistol's battery cannot be recharged, this was seemingly retconned by ''Halo: Official Spartan Field Manual''.}} including [[United Nations Space Command]] generators, provided an appropriate adaptor is at hand.{{Ref/Reuse|osfm}} Plasma pistols have a core power output of 100-150 KV at 2~3 dA, but when overcharged, the power output can reach 1.5 MV @ 2~3 dA.{{Ref/Reuse|h3bnet}} 

[[File:HR Grunt&JackalMajors 2.png|thumb|300px|left|An Unggoy fires the plasma pistol's semi-automatic bursts while a Kig-Yar holds a plasma pistol in its overcharged state.]]
===Operation===
{{Quote|The trigger is soft—no feedback—there’s no break that tells you when the overcharge is gonna kick in. First time I did it was on accident and it damn near sprained my wrist.|Anonymous UNSC E2-BAG/1/7 serviceman{{Ref/Reuse|h3bnet}}}}
While weak on its own, the plasma pistol has a wide variety of functions and becomes deadly in large numbers. The plasma pistol has two modes of fire. The first option is rapidly firing the semi-automatic short bursts of plasma; these plasma bolts are capable of quickly degrading dissipative [[Energy shielding|energy shields]] or vaporizing flesh.{{Ref/Reuse|waypoint}} The second option is holding down the trigger to overcharge the weapon's energy output and, upon releasing the trigger, the weapon fires a scaled burst—a blast of plasma that briefly tracks a targeted enemy.{{Ref/Reuse|evg}}{{Ref/Reuse|h4evg}} The large bolt from the scaled burst has increased damage, but notably carries a devastating short-range EMP effect that can disabled capacitors in electronic equipment, armor, and vehicles on impact.{{Ref/Reuse|osfm}}{{Ref/Reuse|evg}} However, after the overcharged bolt is fired, the pistol will automatically overheat. Until it cools down, the pistol cannot be fired again, giving an enemies enough time to counterattack.{{Ref/Reuse|hrgameplay}}

====Semi-automatic bursts====
When rapidly tapping the trigger, the plasma pistol will fire small bolts of plasma at an exceptional rate of fire.{{Ref/Reuse|evg}} The semi-auto firing mode can be used until the weapon overheats, after which it must cool down for a few seconds before it can be used again. As the weapon approaches low battery, it may sputter and fail to fire.{{Ref/Reuse|h3gameplay}} These bolts deal little damage to targets protected by energy shields, though still more than most kinetic weapons. Against unarmored targets, though, the lethality of the plasma pistol is extreme. Injuries inflicted to a victim are severe third-degree burns, this level of injury causes the wound to be cauterized instantly upon impact.{{Ref/Novel|TFoR|Page=328}} Body fluids would be subjected to flash vaporization,{{Ref/Reuse|waypoint}} inducing a strain or a shock on the body after impact.{{Ref/Novel|TF|Page=22}} Fluids trapped in organs or arteries, in addition to the rapid expansion of heat, would cause ruptures or small explosions causing additional damage to the target.{{Citation needed}} Should the plasma bolt strike cover, the impact can cause splash damage by flinging heated debris, though the blast radius is smaller than most Covenant explosive weapons.{{Ref/Novel|TCP|Page=15}}

====Scaled burst====
[[File:HU UnggoyKilledByOvercharge.png|thumb|220px|A trio of [[Unggoy Minor]]s being disintegrated by an overcharged bolt from [[Myras Tyla]]'s plasma pistol.]]
{{Quote|How the foxtrot does it track anything? Whatever—I guess that’s why I carry an em eh five instead of a [[TACPAD]].|Anonymous UNSC E2-BAG/1/7 serviceman{{Ref/Reuse|h3bnet}}}}
If the plasma pistol's trigger is held for a few seconds, the plasma at the charging poles will gather into a large spherical mass. Holding down the trigger continuously drains the battery.{{Ref/Reuse|h3gameplay}} Releasing the trigger will fire a single bolt of larger size than usual. This bolt, if aimed correctly, will track its target for a short distance if they attempt to dodge. The overcharged bolt creates an [[electromagnetic pulse]], stunning most electronics and even melting some systems.{{Ref/Novel|FS|Chapter=8}} If the target is protected by energy shields, all but the strongest shields will break, allowing their body to take damage.{{Ref/Reuse|enc11}} If the overcharge strikes a vehicle, it will be temporarily disabled and rendered helpless for several seconds.{{Ref/Reuse|osfm}} As such, even the weakest Covenant infantry can thwart an assaulting [[SPARTAN programs|Spartan]] or a vehicle, forcing their foe to retreat or creating an opening for their allies. Should an overcharged bolt strike an unarmored flesh target, it will result in instant death.{{Ref/Novel|TF|Page=81}} During the [[Battle of Cleveland]], [[Myras Tyla]], striking an [[Unggoy Minor]] trio with her plasma pistol, disintegrated three Unggoy rapidly from a single overcharged bolt strike.{{Ref/Comic|Id=HUI3|Comic=Halo: Uprising|Issue=[[Halo: Uprising Issue 3|3]]}}

===Development history===
{{Quote|It’s a damned ray gun—how come we don’t have ray guns?|Anonymous UNSC E2-BAG/1/7 serviceman{{Ref/Reuse|h3bnet}}}}
The plasma pistol's origin dates as far back as the Sangheili society before their encounter with the [[San'Shyuum]].{{Ref/Reuse|enc22p291}} Reverse-engineered from a [[Forerunner]] tool of indeterminate function,{{Ref/Reuse|waypoint}} early plasma pistols, such as the {{Pattern|Zo'klada|plasma pistol}}, were designed and forged by the Sangheili centuries prior to the Covenant's formation. Following the [[Writ of Union]], the San'Shyuum incorporated several design improvements to the plasma pistol, including a less volatile plasma generator core and the addition of overcharge safety restrictors, the latter of which granted the function to fire a scaled burst as a large sustained expenditure of energy.{{Ref/Reuse|enc22p291}}

The weapon's success in the field has led to very few change in its design since the earliest models first enter production,{{Ref/Reuse|evg}} though this may also be the result of the San'Shyuum's restrictions over legacy designs,{{Ref/Reuse|enc22p291}} which likely also informed the Covenant's centralized manufacturing control.{{Ref/Reuse|waypoint}} That being said, there were cases of superficial and functional changes, as the most common plasma pistol design—the [[Eos'Mak-pattern plasma pistol|''Eos'Mak''-pattern]]—is associated with numerous sub-variants.{{Ref/Reuse|waypoint}}

After the [[Great Schism]] and the dissolution of the Covenant, along with its centralized manufacturing control, new variants of the plasma pistols have appeared in a bewildering variety of casing styles and adornments.{{Ref/Reuse|waypoint}} Furthermore, in the absence of the San'Shyuum's restrictions over legacy design templates, the production of pre-Covenant variants has also resumed.{{Ref/Reuse|enc22p291}}

===Usage===
{{Quote|It's great in built-up areas and clearing buildings. Anything over a couple dozen meters though? Not so much.|Anonymous UNSC E2-BAG/1/7 serviceman{{Ref/Reuse|h3bnet}}}}
During the early interstellar expansion period of the Sangheili's history, the precursor of the plasma pistol was employed by Sangheili clan warriors during skirmishes on colony worlds.{{Ref/Reuse|enc22p291}} With the formation of the Covenant, the weapon became the standard sidearm for most Covenant infantry.{{Ref/Reuse|osfm}}{{Ref/Site|Id=h4guide|URL=https://www.halowaypoint.com/en-us/intel/inteldetail/e88138bb-9086-41d3-bc01-acd14eb22bfc/plasma-pistol|Site=Halo Waypoint|Page=Halo 4 Interactive Guide - Plasma Pistol|D=01|M=05|Y=2013|LocalArchive=Halo 4 Interactive Guide#Covenant Weapons}} The weapon was effective and ideal in close quarters, as it provided a high rate of fire and reasonable accuracy over short distances.{{Ref/Reuse|evg}} It was commonly used by members of the lower caste, such as the Unggoy, Kig-Yar, and Yanme'e; these species are often deployed in groups, making their plasma pistols deadly in high numbers.{{Ref/Reuse|enc22p291}}{{Ref/Reuse|enc11}} The Kig-Yar and high-ranking Unggoy, like the [[Unggoy Ultra|Ultra]], frequently utilized the scaled burst function.{{Ref/Reuse|hrgameplay}} Sangheili were known to use the plasma pistol as a sidearm,{{Ref/Novel|FS|7}} or even [[dual-wielding]] the plasma pistol with an [[energy sword (fiction)|energy sword]].{{Ref/Novel|Id=goopro|GoO|Prologue}}{{Ref/Film|TFoRAS}}

Due to their prevalence, plasma pistols were often scavenged by humans from the battlefield;{{Ref/Reuse|h3bnet}}{{Ref/Level|H2|H2:Gravemind|Gravemind}} even [[Spartan]]s were known to pick up the plasma pistol from fallen enemies.{{Ref/Reuse|enc11}}{{Ref/Novel|GoO|15}}{{Ref/Novel|GoO|24}}{{Ref/Novel|FS|2}} Plasma pistols were also recovered by humans for personal use; guards in the [[Eridanus Secundus]] [[Insurrectionists|rebels]] had concealed plasma pistols in their possession.{{Ref/Novel|FS|28}} Although the UNSC first encountered and [[Type classification system|catalogued]] the plasma pistol during [[First Battle of Harvest|the first contact]] with the Covenant in [[2525]],{{Ref/Reuse|waypoint}} the exact mechanism by which the plasma pistol functions was still under investigation by the UNSC in [[2552]], notably being one of the many Covenant weapons featured in [[Robert McLees (ship designer)|Doctor Robert McLees]]' publication ''[[Machines, Materiel and Munitions from the Human-Covenant Conflict, 2525 - Present]]''.{{Ref/Reuse|h3bnet}} 

Following the Human-Covenant war, the plasma pistol remains an attractive weapon for both Covenant splinter factions and human criminals, as the weapon is simple to use and requires almost no maintenance.{{Ref/Reuse|osfm}} Without the Covenant strict and centralized manufacturing control, both old and new variants of the plasma pistol have become a common sight.{{Ref/Reuse|enc22p291}}

==Gameplay==
===Advantages===
The plasma pistol is a great close-to medium range weapon. While it can't inflict high damage at long range, the plasma pistol can be used at a distance if the user fires slowly and aims carefully by leading the target. It is extremely efficient at killing "soft" targets, while dealing large amounts of damage to a heavily armored target. Its overcharge ability is extremely dangerous to shielded infantry, and to non-shielded infantry. Because of the extreme temperatures released, a vehicle running on a hydrogen engine, or one that is lightly covered, can be damaged or disabled if the overcharged bolt hits it — in addition to the high temperatures, the electromagnetic bottle containing the plasma can produce an EMP which can disable any electronic device within range. When compared with the [[Okarda'phaa-pattern plasma rifle|plasma rifle]], the plasma pistol's non-overcharged firing mode is far more accurate at medium and long ranges, although the plasma projectiles tend to arc downward at long range. SPARTANs and Sangheili have the ability to dual-wield plasma pistols, doubling their efficiency in close- to mid-range combat situations. If fired fast enough, the high velocity of the plasma projectile coupled with the force of the kinetic impact, can knock over, or stun infantry.

===Disadvantages===
The plasma pistol, when fired continuously, or when an overcharged bolt is fired, will overheat because of the rapid cycling, loading, ignition, and release sequence of energy. To prevent the weapon from being damaged, the Type-25 DEP temporarily shuts down and opens a cooling vent to allow the excess heat to dissipate before the weapon reactivates. This process leaves the weapon temporarily inoperable. Infantry who are not aware of the function of the plasma pistol can get killed because of this. Human military experts and scientists do not understand how Covenant plasma weapons work, or how they are recharged; as such when the battery is depleted the plasma pistol must be discarded or replaced. At 10% charge level the plasma pistol will begin to misfire, this is due to the battery's inability to deliver enough energy to start and complete the ignition and release phase of operation. As such this hampers the operators use of the weapon. Continuously holding down the trigger while in overcharge mode will rapidly deplete the energy source, and if not careful the weapon can be wasted before firing a single round. Another disadvantage is its short range which is about 10–25 meters depending on the charge level.

Although the plasma pistol can strike a target at long ranges, it is not suited for long-range combat, due to two distinct properties of the weapon's operation. The first is the rate of thermal expansion which is determined by the rate of the bloom of the bolt; "blooming" is the result of plasma breakdown in the air at energy densities of around a megajoule per cubic centimeter. This effect causes the plasma to defocus and dissolve into the atmosphere. It can be more severe if there is fog, smoke, or dust in the air. As the bolt is accelerated away from the "barrel" of the weapon the plasma begins to decay as a result of the weakening magnetic field. Speed also factors in to this, the faster the bolt is accelerated, the farther the bolt will travel before the temperature of plasma begins to decay and the magnetic field becomes unstable and finally dissipates. As the bolt loses velocity it also loses kinetic damage as it travels longer distances.

Plasma pistols are used by the Covenant against humanity.{{Ref/Film|Id=Contact|TV|Episode=Contact}}{{Ref/Film|Id=Reckoning|TV|Episode=Reckoning}}
==Trivia==
* The plasma pistol was inspired by the "[[marathongame:Zeus Class Fusion Pistol|Zeus Class Fusion Pistol]]" from the ''[[Marathon]]'' series. Like the Fusion Pistol, the plasma pistol is a reasonable-damage single-shot weapon with an overcharge mode. However, the Fusion Pistol's overcharge was far more deadly in-game and could kill nearly any enemy in the game, with one limitation: if the gun was left overcharged for too long, it would explode violently, killing the wielder.
* In all of the mainline ''Halo'' games (except ''Halo 4''), if the player remains idle while wielding a plasma pistol, the player character will pull the top off the pistol, showing the plasma pistol's upper firing coil.
* In [[Wikipedia:Konami|Konami]]'s ''[[Wikipedia:Super Bomberman R|Super Bomberman R]]'', the Plasma Pistol is the weapon and special ability used by the [[Grunt|Grunt Bomber]].
* The plasma pistol is the main facilitator for the [[Noob Combo]], in which a player uses a plasma pistol's scaled burst to take down the shields of an enemy before using a headshot-capable weapon (such as the [[BR55 battle rifle]]) to headshot the unshielded enemy. In ''[[Another Day at the Beach]]'' from the ''Halo 2'' [[Multiplayer Map Pack]], [[Butkus]] and [[Fones]] ([[Marcus Stacker]] in ''[[Halo 2: Anniversary]]'') effectively used this combo to take down a Sangheili that had taken [[Walpole]] hostage.
