Species: Gazadean (Deathwalker)
Appearance: An eight foot tall, six powerful legs, armor plated, shiny and reflective, rust colored, Beetle-like with two small dexterious forward armatures that fold flat ageinst the underside, but cannot use traditional weapony but has the abilities to use much heavier weapons then the smaller castes.
Background: The only survivor of a IHU strategic strike, on a brood caste that shown the most predevelopment vunerabilities, having been born on earth and lived there for two long years, he is to be feared by both humans and parasite.
Special abilities: Heavy weapon use, small weapon restriction, refection, computer use, survivor, armored, slow regeneration.
Anything else: He likes beetles, and enjoys the taste of humans.
Name: kash de'var (literally translates as meatbag)
Species: Virtala
Appearance: It's a shape changer, capable of reconfiguring it's appearance, while it generally great difficulty doing so with great accuracy, it can generally get the rough appearance close enough that from a distance it would look like whatever it has taken the appearance of.
Abilities: Very few apart from it's shape changing abilities. Although it is capable of wielding significant muscle power, it is somewhat weaker than most other parasites. It keeps a collection of various bones and clawlike bone structures for use and can produce claws and teeth easily an although it cannot grow new ones, it can preserve bones and muscle structures of creatures it has "eaten". It can absorb a dead(or living if it's unconscious) creatures and can use their biology to grow itself. It can quickly disconfigure into a "melt" form that resembles a chunky blob. This form is what it uses when it is feeding, it is a rather impractical form as it has difficulty moving with speed or moving, but it is useful as it can use it to squeeze into small gaps and grip onto prey, wrapping itself around them. It is capable of surviving large amounts of trauma (unloading a pistol clip into it would probably kill it but a few bullets it can survive). It fears fire, and extreme heat can kill it. It can gain and lose mass at will. leaving behind the stuff it doesn't need in little goopy blobs of bad smelling stuff. If it becomes badly injured it can regain it's mass by eating creatures.
It is utterly incapable of communication though it can easily understand the others. It is primarily concerned with eating anything in it's way, and pretty much the only reason it leaves the other parasites alone is because they all have been biologically engineered to have a chemical in them that makes them seem utterly repulsive.
It primarily senses through it's sharp sense of smell, but also has eyes (of other creatures) that it can use to see with.
In order to take on a form, it needs to feel every crevice it can, but even then it can do so with a great deal of accuracy, it will still look wrong and examining it closely will reveal that it is a poor copy. It can change it's skin pigmentation to camouflage in though.
Background: it was an experiment into an advanced form of biological computer, when the "computer" became animated and tried to consume one of the alien's limbs they realized it's potency as a biological weapon. it still retains much of the "circuitry" that allows it to survive and regain intelligence in the event of losing most of it's mass. They are mostly used for infiltrating by taking on the shape of different enemies and wreaking havok behind enemy lines, it's favorite trick is to take on the form of the enemy and pretend to be dead, or better yet, wounded. Then when a soldier comes to investigate it will latch onto them and eat them (and if they are that close they usually don't stand a chance).
