Von Ryan’s Leapers are swift, agile Tyranid bioforms, cunning hunters and stealth ambushers that are especially lethal when fighting in dense terrain. Packs of Leapers lie in wait like living mines, lurking at the optimum locations to cause as much damage as possible. When they sense the perfect time to strike, they burst forth to butcher all around in a murderous frenzy.

Termagants are fast, agile and cunning creatures. When a Tyranid Hive Fleet descends upon a prey-world, Termagants scuttle forward on four legs whilst unleashing torrents of fire from the bio-weapons that serve as their forelimbs.

The Tyranid hive fleets are rapacious alien swarms that flow from beyond the galactic fringe to devour all life. When the Tyranids attack they do so in unstoppable numbers, unleashing nightmarish bio-weapons upon their victims.

Termagants are scuttling predators that attack in huge swarms, armed with living weapons that spit flesh-eating organisms and venomous spines. Originally spawned to roam the tight arterial passages of hive ships and hunt intruders, Termagants harry their prey with a hail of firepower, seeking always to outflank and envelop their victims as they erode their numbers.

Hormagaunts are swarming shock troops, seeded onto prey worlds in their billions. As simple hunter-slayer organisms, spawned Hormagaunts can be left to rampage across battlefields and populations, wearing down defence lines and forcing the prey to expend lives and ammunition. Many formidable bastions have been buried in literal mountains of these chitinous horrors, driven by the will of a terrible synapse beast.

The Tyrannofex has the armour and fortitude of a living battle fortress and its weaponry eclipses that of its foes' most powerful battle tanks in both quantity and devastating potential.

The Deathleaper is a rare and advanced development of the Lictor strain, perfectly evolved to act as a terror weapon. This apex Lictor possesses an instinctive understanding of how to spread fear through hostile forces and prey populations alike, using its skills in stealth, infiltration, and assassination to sow paranoia and dread before the hive fleet attacks en masse.

Hive Guard are heavily armoured gun-beasts bound to extremely powerful symbiotic bio-weapons. They are created to guard the Tyranid Hive Ships and capillary towers that stand sentinel over prey worlds, until such time as intruders come within range of their deadly weapons.

Neurolictors are nightmarish living weapons of psychological warfare, engineered to implant mind-altering parasites and project a neural disruption field that provokes atavistic terror responses in even the most hardened prey. As an offshoot of the Lictor bioform, Neurolictors possess a nigh-supernatural ability to evade notice – which renders their sabotage all the more terrifying, as these insidious effects often seem to emerge from out of thin air.

When Tyranids invade, the Broodlord leads his followers into battle, often appearing from sewers or hidden vents to cause untold carnage amongst the enemy army.

Gargoyles are often the first wave of a Tyranid swarm to be seen in battle.

Tyranid Warriors are the most adaptable of all the Hive Mind’s bioforms. They are efficient killing machines with the ability to employ a wide variety of bio-weapon symbiotes. On the battlefield they are found fighting in both close quarters and at long range, and form a vital link in the Tyranid swarm, acting as relays through which the Hive Tyrants issue their commands.

Neurogaunts scuttle forward in seething masses, driven on by the parasitic neurocytes that cling to their backs. Their primary purpose is to protect the synaptic node-beasts coordinating invasion swarms, while projecting their command signals throughout the wider swarm. It is a task they go about with single-minded savagery, slashing, biting, and dying with mindless vigour.

Each Norn Emissary is a purpose-bred beast, spawned by its Norn Queen to accomplish a specific and singular objective – be it hunting a strategically gifted commander, abducting a knowledgeable prey-being, or pursuing some other ineffable goal. These colossal heralds of the Hive Mind's agenda meld terrifying psionic potential with speed, intelligence, and monstrous strength, ensuring that a Norn Emissary is more than equal to its alien task.

A Psychophage stampedes into battle at a frightening speed. They devour any prey organism in their paths, but especially favour those victims with psychic abilities. How they metabolise such esoteric powers is unclear, but doing so allows them to project surges of psychocorrosive ash that deflagrate their victims’ minds and souls.

Barbgaunts are little more than living weapons, their bodies and biological cannons slaved to the will of a pulsating ganglio-parasite that piggybacks them into battle. Once there, they unleash volleys of chitinous barbs that detonate with the fury of violent muscle-spasms, transfixing nearby victims with a hail of jagged projectiles.
