Husk

Husks are bio-mechanical zombie-like creatures created by the Reapers from other species in order to serve as foot soldiers, as well as an instrument of psychological warfare against other species the Husks once belonged to.

Creation
Husks are created by impaling a sentient victim on a device nicknamed "Dragon's Teeth." Gradually, the skin, organs and fluids of the victim are converted into cybernetic materials. While Husks typically display behaviour and intelligence compared to that of Zombies, others are heavily modified to gain new abilities the original species is not capable of.

Variants
Husk - Former Humans converted for use by the Reapers, the standard Husk will mindlessly run towards hostiles and attempt to maul them. Due to the apparent ease in killing them, Husks are reliant on numbers as their primary advantage.

Abomination - Similar to standard Human Husks, albeit with red colouration, Abominations will self-destruct as their primary form of attack.

Cannibal - Husks created from converted Batarians, Cannibals serve as front line troops and are armed with an automatic arm cannon. Cannibals are named for their ability to rapidly heal and grow chitinous armour by consuming the remains of dead Husks.

Marauder - Husks converted from Turians, Marauders serve as field commanders for Husks. Equipped with personal energy shields and modified Turian weaponry, Marauders are also capable of projecting chitinous armour onto nearby Husks.

Banshee - Husks derived from Asari, Banshees make extensive use of biotic powers to inflict devastating damage on the Reapers' enemies. This biotic aptitude may be factored towards by the Reapers only converting Ardakt-Yakshi, Asari with enhanced biotic powers as a side effect of a rare neurological disorder.

Brute - A unique variant of Husk, Brutes are an amalgamation of Turian and Krogan, fused and maintained by Reaper technology. Brutes are heavily armoured, highly aggressive and can inflict extreme damage at melee range.

Ravager - Husks converted from Rachni, Ravagers serve as living artillery turrets. Although they can inflict major damage at long range, Ravagers are vulnerable to damage towards the sacs on their undersides. However, bursting these sacs will release Swarmers in retaliation.

Scion - a fusion of three Human Husks, Scions are heavily armoured and armed with an arm cannon.

Praetorian - a construct made from thirty Husks, Praetorians are heavily armoured, shielded and armed with particle beams, a "death choir" area-of-effect attack and claws. As evident by the design of its armour, the Praetorian is designed and utilised by the Collectors.

Harvester - a Husk made from a large winged creature of the same name, Harvesters are heavily armoured, armed with head-mounted cannons and serves as an aerial troop transport for ground-based Husks.

Adjutant - a biological weapon created by Cerberus using Reaper technology, Adjutants function as pack hunters in service to the terrorist organisation during their occupation of Omega. Distracting their targets with whispers before ambushing them with unstable mass effect fields, and infecting them to convert them into new Adjutants. Some xenobiologists have theorised the Adjutant virus was derived from a long-extinct species wiped out by the Reapers.
