Necromorph

Overview
The Necromorph is not a parasite but an alien scourge. The infectors prefer to wait for the host to die or wait for their prey to be cornered before they infect the organism. For some reason the infector won't usually attack a living organism that is bigger then a five to six foot human, possibly it could be that it worries it can't stand a chance. For the infector the corpses don't fight back, therefore an easy target for multiplying. 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. The Necromorphs are not at all unintelligent, these super beings can lose a leg, arm and even their head. Then perform what to you seems like a fatal wound and act dead. Once you have killed the being it waits for you to wander close to its body. Expect the worse to come.

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, there bodies are more durable to perforation (For example, black slashers).
 * INFECTOR:A bat-like, eyeless necromorph with a stableizer which is a massive 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 avoid loving organisms unless the feel threatened by them, mostly just infecting dead bodies.

Female slashers are not as aggressive as males but they are able to spit stomach acid upon their victims. Black slashers ( their enhanced variant) are much more resilient, can't spit acid like the female variant but strike harder, move faster, they can't regrow limbs but what do they care they're still coming for you.
 * SLASHER: These are the most common form of necromorph, only because there are plenty of dead humans around to infect and to be infected. their arms have been shifted to their shoulder blades and their hands grow sharp blade like spikes from their palms. an additional set of arms grow out of their abdomen. They can run at high speeds and will try to get new hosts for the alien scourge known as the INFECTOR. 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 suction cups to crawl on walls and ceilings both in normal and zero-G environments, 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, very sad and sadistic of the creators of the game. They have a long cut running down their back and 3 large tentacles that come out of the crevice in its back, these can be used as a whip or they can use the needles 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 female and male necromorphs, since these critters are big in size 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 to a certain degree, they release a swarm of tiny necromorphs(made out of dead skin cells.). These will latch on to Isaac and make him slow down while health rapidly decreases. Isaac will have to come to a complete stop to shake them off.(Later on, Lurkers and living body limbs called COMPONENTS 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 a body that is very hard to take down because of their twitches 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. Once they have spotted Isaac they instantly spring into eliminate mode. Don't get sucked into a corner with one of these.


 * LEAPER: A necromorph which has mutated its lower half and it either removed or linked 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 vaccuum there is no sound which makes it harder to detect. It has an enhanced variant.


 * BRUTE: A truly monstrous creature, the Brute is formed from multiple bodies fused together. It has heavy layers of skin that is exactly like armor on its massive arms and head 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, that is if it even has one. Fortunately it is rare and it lacks armor on its legs so attacking its back and legs gives the best chance of victory. And if you have precise aim there is weak point in their shoulders. Shoot these points and you will be quite relieved. 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 aboard the Ishimura, and exhale a deadly noxious substitute using a large, leathery sack-like protrusion on its spine, its like it developed lungs on its back. 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 wrists. When killed it will purposely fall on the ground face first and break into 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 try to tear you in half or cut off a limb. This type can be heard coming before its appearance, due to the 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. Ain't that great.


 * SWARMER: These are somehow formed inside of the pregnant necromorphs, apparently from chunks of meat. They are small 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.Bad combination.


 * EXPLODER: These necromorphs have their legs fused into one spindly limb. Their dominant arm is mutated into a huge sack of chemicals, which explode if struck hard enough. If the sack is dismembered it can still attack Isaac but it is very weak. Its head is split in two to create a mouth and bit Isaac in half, yes, in half! Before it cant do so use your kinesis gun to grab its exploding sack and launch it right at him.


 * HUNTER: Forged by Dr. Mercer on the USG Ishimura himself. It is a large necromorph that if it's limbs are lost or it's takes damage it can rebuild 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 immediately stab you and slice off your limbs one by one with it's massive bladed arms. He'll stare into your eyes as he does it, watching you slowly lifting your hand for mercy.
