{{Quote|These are Crawlers—fast and mean, but pretty easy to deal with.|[[Jared Miller]] describing Crawlers to [[Fireteam Crimson]]}}
The '''Promethean Crawler''' is an autonomous [[Forerunner]] defense construct, serving as part of the [[Ur-Didact]]'s mechanical [[Promethean]] army as a means of asymmetrically combating the [[Flood]].<ref>[https://www.youtube.com/watch?v=qQtOU5gZfzI&feature=g-user-u '''YouTube''' - ''Halo 4 Fiction Panel from SDCC 2012'']</ref><ref name="gameplay">[https://www.youtube.com/watch?v=ymu-1MDzb9M&feature=g-user-u '''YouTube''' - ''Halo 4: A New Campaign and Halo Infinity Multiplayer Panel from SDCC 2012'']</ref> 

== Overview ==
Crawlers are small, quadrupedal machines capable of both ranged and close-quarters combat, using a built-in [[Z-110 Boltshot]]{{Ref/Reuse|gi}} as their primary weapon; this weapon disintegrates targets to prevent their biomass from being co-opted by the [[Flood]].{{Ref/Reuse|gameplay}} Unlike the majority of [[Forerunner]] automatons, they lack [[anti-gravity technology|anti-gravity capabilities]] of any kind and instead rely on their four legs for locomotion. They are however capable of vertically scaling structures and leaping great heights in order to get tactical advantage. Crawlers are ferociously aggressive, having been specifically designed to hunt down and eliminate any foreign threats, their inorganic nature making them immune to Flood infection.{{Ref/Reuse|gameplay}} They travel in large packs and work together to destroy enemies by overwhelming them from every conceivable angle, relying on skirmishing tactics.{{Ref/Reuse|characters}}

Crawlers are often directed by [[Promethean Knight]]s, who regard them as cannon fodder. They are protected by [[Promethean Watcher|Watcher]] [[Sentinel]]s, which can offer them cover in the form of small [[Z-90 hardlight shield|hardlight shields]] or create new Crawlers from raw materials in the ground. In addition to the basic type of Crawler, [[Alpha Crawler|a more heavily armed unit]] and [[Crawler Snipe|a long-range unit]] are also employed.<ref>[http://halo.xbox.com/blogs/Headlines/post/2012/06/20/The-Halo-Bulletin-62012.aspx '''Halo Waypoint''' - ''The Halo Bulletin: 6.20.12'']</ref>

The [[Ur-Didact]] originally designed the Crawlers for his Prometheans to use against a number of infantry threats, and, eventually, the [[Flood]]. They were created to target and destroy organic matter, overcoming their enemies with numbers.<ref>'''[[Halo: Fractures]]''', ''"[[Promises to Keep]]"'', ''page 109''</ref> It has also been theorized that they were sent into Flood strongholds to soften their infantry numbers before more valuable assets were sent in.<ref name="H4EVG">'''[[Halo 4: The Essential Visual Guide]]''', ''page 50''</ref> Numerous Crawlers were encountered by [[UNSC]] and [[Jul 'Mdama's Covenant|Covenant]] personnel on the [[shield world]] [[Requiem]] in mid-[[2557]] during the [[Battle of Requiem]], and later during the [[Requiem Campaign]] in [[2558|February 2558]].<ref>'''[[Halo 4]]''', ''[[Spartan Ops]]''</ref> Crawlers also accompanied the Didact during his [[Mission to Installation 03|attack]] on the human forces on [[Installation 03]] and at the [[Composer's Forge]].<ref>'''[[Halo: Escalation]]''', ''[[Halo: Escalation Issue 8|Issue #8]]''</ref><ref>'''Halo: Escalation''', ''[[Halo: Escalation Issue 9|Issue #9]]''</ref> By October 2558, Crawlers had been taken control by [[Cortana]] and the [[Warden Eternal]] to serve in the [[Created]], during which Crawlers sported a dark gray body color with bright red highlights.<ref name="H5G">'''[[Halo 5: Guardians]]'''</ref>

=== Behavior ===
Crawlers exhibit animal-like behaviors. They can be found "sleeping" outside of combat, scratching themselves with a back leg similar to wolves or dogs, and even showing distress by whining if kept isolated from other Crawlers.<ref name="Guardians">'''Halo 5: Guardians''', campaign level ''[[Guardians]]''</ref>

== Subtypes ==
* [[Alpha Crawler]] - a variant which leads packs of lesser Crawlers and utilizes a [[Z-130 Suppressor]] in combat.
* [[Crawler Snipe]] - a further upgraded long-range Crawler variant with a built-in [[Z-750 binary rifle]].
*[[Lightrifle Crawler]] - a further upgraded assault Crawler variant with a built-in [[Z-250 lightrifle]] found in the Spartan Ops mission Switchback.

== Trivia ==
{{Linkbox|gameplay=yes|gallery=yes|gallerypage=Images of Promethean Crawlers}}
* Promethean units were named for chess game pieces during ''Halo 4''<nowiki>'</nowiki>s development. The Crawler was originally called the Pawn. It remains the character model's file name in the game code. Only the Knight retains its chess piece name.
* The Crawler, along with the [[Promethean Watcher]], was first seen in a leaked image from [[McFarlane Toys]].
* In the ''[[Spartan Ops]]'' mission [[Scattered/Switchback|Switchback]], [[Z-250 lightrifle|lightrifle]]-armed [[Lightrifle Crawler|Crawler]]s can be found, and they are seen holding the weapon in their front right foot as opposed to in their body like other Crawler units.
