The critical reception of the Reapers is generally favorable. ''Kotaku's'' Gergo Vas considered Shepard's multiple encounters with the Reapers to be some of the original trilogy's most iconic moments.
Evan Narcisse, also from
Kotaku, considered the Reapers to be frightening antagonists as they are entities that felt like "un-life" and represent the continual malevolent erasure of sentient life forms. He said the conversation with Sovereign in Virmire is one of the most chilling encounters he has ever experienced in a video game, and later described the scene as the moment where
Mass Effect went from being a generic sci fi story to "a story about the larger existential threat that the universe faced". Sal Basile from
Ugo.com considered the first time Shepard encounters a charging Husk after it is detached from a "dragon's teeth" pillar and Sovereign's reveal of the truth about the Protheans and the Reapers to be among the series' most shocking moments, setting a defining tone that it is not a simple "lasers set to stun" space game. Stacey Henley from
The Courier said the husks are much more sinister and horrifying then the typical idea of a zombie with rotting flesh, as it represents "the notion of our bodies deleting themselves cell by cell and adding cybernetics in their place". She noted that
Mass Effect "really leans into the unsettling horror of these creatures" when non-human Husk variants are introduced in the third game. IGN staff enjoyed the encounter with a smaller Reaper ship towards the end of
Mass Effect 3 as they were afforded the opportunity to equip the M-920 Cain superweapon. Harbinger placed No. 39 on IGN's list of top 100 video game villains. In 2013, the Reapers placed No. 97 on ''GamesRadar's'' list of 100 best villains in video games, and No. 21 on a reader's poll organized by
Guinness Book of Records for their list of top 50 video game villains of all time. Conversely, Ron Whitaker from
The Escapist included the Reaper-Human Larva in his list of terrible video game villains. He criticized the lack of fear the creature inspires and the boss fight to be overly easy in difficulty, though he still considers the Reapers as a whole to be a believable threat. A much-discussed fan theory arose in response to fan outrage over the
controversial ending of Mass Effect 3, which suggests that its ending is all an illusion caused by the Reapers indoctrinating Shepherd. The theory proposes that Shepherd's prolonged exposure to Reaper technology throughout the trilogy as well as experiences of bizarre dream sequences in
Mass Effect 3 indicated signs of gradual indoctrination by the Reapers, bringing the battle with the Reapers down to an intrinsic level as Shepard fights the Reaper's influence in their own mind during the ending sequence. BioWare staff declined to comment when questioned about the fan theory, whereas Karpyshyn was of the view that fans would still be dissatisfied had the developers of
Mass Effect 3 gone with the alternate endings he proposed.
Analysis Tauriq Moosa from
Polygon suggested that the idea of an all-consuming uncaring god stretches across BioWare's most popular franchises, including
Mass Effect. He observed that Shepard spent the entire trilogy preparing for war against god-like beings who "essentially,
created existence", and compared the Reapers' cycle of destruction by design to "children with an
ant farm and magnifying glass". David Callahan, an associate professor at the
University of Aveiro,
Portugal, described the Reapers' acts of genocide as their practice of intervention by altering a whole species' destiny or even terminating them, noting that this is not unlike what settler-invader peoples historically did, and are still doing, to
Indigenous peoples around the world. ==In popular culture==
