Necromorph

Overview
The Necromorph is a parasitic being. The infectors prefer to wait for the host to die before they infect an organism for some reason. If a living human is infected, their body is supercharged, and they become invincible. The mutated being must be mauled in a variety of ways to kill it, as most are able to sustain severe trauma before falling and upon losing a limb are able to adapt themselves to continue functioning.

Behind the Scenes

 * Their name comes from the Greek words Necros (corpse, in the sense of dead) and morph (form), literally "dead form", much in the same way that Xenomorph means alien form.

Variation
The necromorphs come in a lot of different types, Here are a few:

On the spot mutations can result in an enhanced version of regular necromorphs (For example, black slashers).
 * INFECTOR:A bat-like, eyeless necromorph with a huge stinger. The stinger is driven through the forehead, (or a mass of tentacles that seem to have previously been innards is slid down the victim's throat)and the victim mutates into a necromorph depending on hormonal state, age, and even body weight.They will ignore Isaac and instead infect dead bodies in the vicinity unless there are none.

Female slashers are not as aggressive as males and may spit acid upon their victims. Black slashers ( their enhanced variant) are much more resilient, can spit acid like the female variant, strike harder, move faster, and may regrow lost limbs.
 * SLASHER: These are the most common form of necromorph, their arms have 'sunken' into their abdomen and they have grown limbs on their shoulders which end in sharp blades. They can run at high speeds and will try to get new hosts for the parasite. Their look may differ depending on their gender, class of officer and the length of time they have been mutated(some wear trousers, have breasts, have darker skin and scream in a different pitch of voice).

They crawl on all fours and use suctiong cups to crawl on walls and ceilings both in normal and zero-G enviroments, meaning that they may attack from any direction. It has an enhanced variant.
 * LURKER: These necromorphs are dead babies and still retain their infant bodies. They have a long cut running down their back and 3 large tenticles that come out of it, these can be used as a whip or they can use the spikes on the end of them as a long range weapon.

If killed without releasing thir spawn, their contents die as well. Made from pregnant females.
 * PREGNANT: These are the most obese of the necromorph, because of this their speed is hindered but they are still quite fast and use blades ( much like the slashers) to strike at Isaac. Their stomach is their deadliest weapon. When shot in the stomach they release a swarm of tiny necromorphs(made out of dead skin cells.). These will latch on to Isaac and take down health rapidly unless he shakes them off.(Later on, Lurkers will come out instead of a swarm.)


 * TWITCHER: Military personnel who had the unfortunate luck to be turned into a necromorph have the joy of being a Twitcher. They have body armor and are thus harder to dismember. The one thing that sets these apart from normal slashers are their stasis modules, which fused with the necromorph during mutation and instead of slowing itself down sped it up to almost godlike speeds. Their movements are often blurry, and can cross a large room in seconds.


 * LEAPER: A necromorph which has mutated its legs into a single, muscular tail which, as its name suggests, allows it to make leaps across great distances. It can also crawl on walls and ceilings. It is not as resilient as other necromorphs and instead prefers to ambush its prey. It is particularly dangerous in zero-g due to its crawling abilities as it may attack from any direction, in vaccum there is no sound which makes it harder to detect. It has an enhanced variant.


 * BRUTE: A truly monstruous creature, the Brute is formed from multiple bodies fused together. It has heavy armor on its front which it uses to protect itself and to ram opponents. It will stop at nothing to kill its prey and will rip and tear without a second thought. Fortunately it is rare and it lacks armor on its legs so attacking its rear gives the best chance of victory. This variant is seen in the Dead Space: Downfall deleted scene "Graverobber."


 * WHEEZER: This species stays anchored to one spot in a crouched position. Its purpose is to filter the breathable air abord the Ishimura, and exhale a deadly noxious substitute using a large, leathery sack-like protrusion on its spine. Isaac must destroy all of these in the Hydrophonics sector to rehabilitate the life-support systems.


 * DIVIDER: The divider is a long bodied necromorph that has no bone spike coming from its wrist. When killed it will purposely fall on ground face side and break into 3-5 peices which are the 2 hands, head, and 2 feet. The body parts will grow tentacles and crawl after you, the head will try and choke you but the others will jump and attack you. This type can be hear coming before its appearance, due to its guttural groans it emits.


 * COMPONENTS-Mutated limbs and heads from a divider. The head type component can infect Issac, turning him into a divider himself.


 * SWARMER: These are somehow formed inside of the pregnant necromorphs, apparently from chunks of meat. They are small with teeth and if you do not kill the pregnant necromorph the right way at least 10 leechs will burst out of it. They have no bones, but they have muscles and they are basically nothing but green goo wih teeth. They move around by throwing themselves to the front of them and if they get close enough to you they will leap on to you and start to eat you just like a crossbreed of leech and piranha.


 * EXPLODER: These necromorphs have their legs fused into one spindly limb. Their dominant arm is mutated into a huge sac of chemicals, which explode if struck hard enough.


 * HUNTER: Forged by Dr. Mercer on the USG Ishimura itself. It is a large necromorph that if it's limbs are lost or it's takes damage it can rebulid itself regrowing it's limbs and lost particles through a chemical in it's blood. It can only be incapacitated with severe burning or by freezing it.If caught by this creature it will immediatly grab you and slice off your limbs one by one with it's massive bladed arms.
