Tyranid Biomorphs - Support Biomorphs: Acid Blood - The alien blood spilt from certain Tyranids is so corrosive that it can eat through ceramite armour and dissolve flesh in mere moments.Acid Maw - The maws of some Tyranids constantly drip with acidic bile.Adrenal Glands - An Adrenal Gland is a Tyranid Biomorph that is commonly developed in the frontline creatures of a Tyranid swarm. Adrenal Glands massively increase the production of adrenaline within a Tyranid bioform, and also saturate their host's bloodstream with other chemicals that boost the creature's metabolism to a hyperactive state of frenzy. This allows the organism to move more swiftly and attack with greater strength. The most common Tyranid bioforms found with Adrenal Glands are Hive Tyrants, Tervigons, Tyranid Primes, Tyranid Warriors, Genestealers, Termagants, Hormagaunts, Rippers, Sky Slasher Rippers, Tyranid Shrikes, Gargoyles, Harpies, Carnifexes, Trygons, Mawlocs and Tyrannofexes.Adrenaline Sac - The Adrenaline Sac is a special container for excess adrenaline which the bioform can use to temporarily enhance its senses, abilities and physical attributes. It does not contain enough adrenaline for extended use and will require refilling after a single use.Blinding Venom - Some Tyranids spit caustic venom at their prey's eyes.Chameleonic Skin - Chameleonic Skin allows Lictors to alter their skin colour to blend into any environment and become all but invisible to the naked eye.Containment Spores - These curved spines are displayed down the length of a Trygon Prime's body that allows the creature to contain and focus their natural build-up of electrical energy to a greater degree than a standard Trygon.Enhanced Senses - Tyranid bioforms' Enhanced Senses are represented by a large grouping of antennae which Imperial autopsies have shown to have created areas of neural meshing which indicates that the Tyranid bioform has essentially become a mobile appendage to its own weapon. Some bioforms have a different version of Enhanced Senses in which the Tyranid organism has highly developed and sensitive sight, smell and hearing. These abilities enable it to locate hidden enemy units much more effectively, often finding even those outfitted with special technology intended to keep them unseen.Feeder Tendrils - Feeder Tendrils are special organs possessed by some Tyranid bioforms such as Lictors and Ymgarl Genestealers that enable them to drain their dead victims' brain matter and cerebrospinal fluid, absorbing all of their memories and learned knowledge in the process. This provides the Tyranids with crucial information about an enemy's strengths and weaknesses, along with invaluable intelligence and reconaissance information about a world whose biosphere has been targeted for absorption by a Tyranid hive fleet.Frag Spines - Frag Spines are studded along the spines of some Carnifexes, composed of explosive Spine Banks or other similar short-range Bio-Morphs that launch as the Carnifex rampages forward and forces their prey to take cover or be shredded with hundreds of chitinous shards.Implant Attack - An Implant Attack is a Tyranid biomorph that is comprised of hollow fangs, barbed stingers, or serrated claws that are capable of inflicting massive internal injuries to a victim and bleeding them to death in seconds, as well as injecting the target with fatal toxins.Leaping - Tyranid bioforms outfitted for leaping take large, bounding steps towards enemy lines and can close for combat more quickly. Hormagaunts, Tyranid Warriors and Rippers are the only Tyranid species able to use Leaping.Optic Membranes - The bioform's eyes have been modified with an extra membrane which can cover the eyes momentarily, allowing it to avoid being blinded by sudden flashes of light.Regeneration - Some Tyranids have the ability to recover from horrendous wounds and injuries that should have proven fatal.Scuttlers - Some Tyranid bioforms have been made more intelligent and capable of greater stealth, as they can make use of terrain to creep closer and closer to the enemy before the initial attack is launched. Genestealers and Gaunts are the only Tyranids able to take the ability.Symbiote Rippers - Symbiote Rippers is a type of biomorph in which a living carpet of Rippers is laid down over terrain which Tyranid organisms walk over. This squirming organic carpet can shuttle large numbers of different Tyranid organisms, forming a tide of biological death that can cross almost any geographical obstacle to reach the foe.Thornback - Thornback is the nickname given by Astra Militarum troops to Tyranids who possess Biomorphs in the form of large blade-like chitin protrusions from their carapace. Thornbacks are often seen charging into ranks of enemy troops using pure body mass as their primary weapon and simply impaling any enemies they come across on their "thorns."Thorax Swarm - The Thorax Swarm is a Tyranid biomorph in which a large, bloated chest cavity is filled with swarms of small parasites. These creatures erupt from openings in their host organism's chest to drown the enemy in a deadly cloud that chews out eyes and crawls down throats. Different types of small creatures may make up these swarms, including:Electroshock Grubs - Electroshock grubs are part of a Thorax Swarm and emit powerful bolts of electricity that arc among themselves as their constantly writhing segmented plates produce electrostatic energy. Anything caught in this energy is reduced to charred remains.Desiccator Larvae - Desiccator Larvae are part of a Thorax Swarm and can latch on to an enemy and within only seconds suck every drop of moisture from their victims, leaving behind only a dry, desiccated husk.Shreddershard Beetles - Shreddershard beetles are part of a Thorax Swarm and once released, instinctively crawl into any nook or crevice on their victims' bodies, such as those between armour joints. They are covered in needle-sharp spines and cannot live for long outside their host, but as they die they explode, covering their victims in a hail of deadly, chitinous needles.Toxic Miasma - This Biomorph consists of vents sprouting from the backs of some Tyranid creatures to release toxic gases comprised of microscopic algal formations into a prey world's atmosphere, most notably the Venomthrope species. Even brief exposure to the miasma gases can cause a victim to choke to death on its own blood.Toxin Sacs - Toxin Sacs are a Biomorph consisting of parasitic glands containing small mites which attach to a Tyranid creature and secrete poisons into the host organism's existing Biomorphs or coat poison over the host's claws, fangs and talons, while the parasite feeds on the host in return. The poisons vary wildly from necrotic venoms to toxins capable of boiling a victim's blood while still in their veins. All of the deadly poisons are swimming with Tyranid phage cells.Venom Sac - This biomorph modifies a Tyranid organism by adding a sac full of corrosive venom beneath its claws and fangs, making its attacks all the more deadly to lightly armoured enemies.Wings - The forelimbs of some Tyranid organisms have been mutated into leathery wings that allow them to move much more swiftly over long distances by flying or gliding. Some organisms also develop more than one set of wings or a lightened exo-skeleton to assist with flight.
