The '''Promethean Watcher''' is a [[Forerunner]] [[Sentinel]] variant.<ref name="evg">'''[[Halo: The Essential Visual Guide]]''', ''page 167''</ref><ref name="H4 Characters">[http://halo.xbox.com/halo4#!an-epic-universe/characters/8c164b48-05e7-4c13-a268-f60ec3a72938 '''Halo 4 Official Site''' - ''CHARACTERS'']</ref> Watchers are part of the mechanical [[Promethean]] forces created by the [[Ur-Didact]] near the end of the [[Forerunner-Flood war]] as a desperate attempt to combat the [[Flood]].<ref>[http://www.youtube.com/watch?v=qQtOU5gZfzI&feature=g-user-u '''Halo Waypoint''' - ''Halo 4 Fiction Panel from SDCC 2012'']</ref><ref>[http://www.youtube.com/watch?v=ymu-1MDzb9M&feature=g-user-u '''Halo Waypoint''' - ''Halo 4: A New Campaign and Halo Infinity Multiplayer Panel from SDCC 2012'']</ref> Watchers acted as the primary defensive drones of the Promethean [[shield world]] [[Requiem]], where they were first encountered by the [[UNSC]] in summer [[2557]].{{Ref/Reuse|H4EVG}}

==Overview==
In the battlefield, Watchers act in a supporting role, assisting Promethean ground units with aerial combat screening and often forcing opponents to engage the Sentinel first. Each [[Promethean Knight]] unit carries a single Watcher or more in the back of their armored carapace, from which the Watcher can be deployed at will. Watchers are essentially low-level [[ancilla]]s based on the Promethean Knight from which they originate. The watcher's AI is housed in its upper carapace above the "head".<ref name="H4EVG">'''[[Halo 4: The Essential Visual Guide]]''', ''page 53''</ref>

The Watcher is capable of healing and augmenting damaged allies, providing them with [[Z-90 hardlight shield|hard light shields]], and can catch and return enemy ordnance, such as [[grenade]]s, with a [[Anti-gravity technology|gravity-displacement field]].{{Ref/Reuse|H4 Characters}} They are armed with a built-in [[Z-110 Boltshot|Boltshot]].{{Ref/Reuse|gi}} Watchers can resurrect destroyed Knights from the small orb of light they leave behind upon death; however, this can only be performed once for each individual Knight.<ref name="Return">'''[[Making Halo 4: Return of the Forerunners]]'''</ref> They are also capable of summoning [[Promethean Crawler]]s to the battlefield by conjuring the Crawlers' forms from raw material in the ground.<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> Watchers are also capable of building [[Z-510 focus turret|focus turret]]s.<ref>'''Halo 4''', campaign level ''[[Infinity (Halo 4 level)|Infinity]]''</ref>

==Appearance==
Unlike the angular appearance of most Sentinels, Watchers have curving carapaces, a defining characteristic of Promethean war machines. They have a number of appendages, including what appear to be legs hanging below the midsection which serve as stabilizers and two large disks on both sides which provide agile lift systems and a coiled energy expenditure from within them. Most of these segments lack physical joints and are held together by energy fields. Above the midsection there appears to be a head with stylized facial features and also two fins which act as motion curators to control movement.{{Ref/Reuse|H4EVG}} Like the other Promethean constructs, Watchers under the [[Ur-Didact]]'s control possess orange lighting, in contrast to the blue-lit appearance typical of other Forerunner constructs.

== Trivia ==
{{Linkbox|gameplay=yes|gallery=yes|gallerypage=Images of Promethean Watchers}}
* The Watcher, along with the [[Promethean Crawler]], was first seen in a leaked image from [[McFarlane Toys]].<ref>[http://attackofthefanboy.com/news/halo-4-enemies-outed-viatoy-box/ '''Attackofthefanboy.com''' - ''Two new Halo 4 enemies outed via…toy box?'']</ref> However, it was first mentioned as the "Watcher Sentinel" several months earlier in ''[[Halo: The Essential Visual Guide]]''.{{Ref/Reuse|evg}}
* The Watcher was called Bishop during the development of Halo 4. The Watcher's model filename is still called "storm_bishop". The Knights are all that survive of the formerly chess-piece-named Prometheans.
** The ''[[Halo: The Master Chief Collection]]'' achievement named [[Remove the Bishops From the Board]], which is unlocked by destroying 1000 Watchers, is a reference to the Watcher's original name, the Bishop.
* An outline of the [[Reclaimer]] symbol, in reality the ''[[Marathon]]'' [[List of Marathon references in the Halo series|logo]], appears on the Watcher's midsection despite [[Bungie]] owning the rights to the ''Marathon'' franchise.
* Shooting the tiny face on the Watcher counts as a [[headshot]] and destroys the whole body. However, the face is so small and the Watcher is protected by weak shields, that aiming for it is not very practical.
* Promethean Knights are capable of deploying multiple Watchers from their body, not just one. This may be due to bugs.
* Watchers can be assassinated in ''Halo 4'', but not in ''Halo 5: Guardians''.
* Watchers are capable of catching player thrown grenades and throwing them back. They can also, as of ''Halo 5: Guardians'', catch and throw back the projectiles shot by [[MLRS-1 Hydra|Hydra Launchers]].
