Hierophant

 The Hierophant is a type of Bio-Titan, collossal organic war machines used by the Tyranids''. ''They are immense creatures, towering over any opponents and bristling with spines, tendrils and Tyranid symbiote weapons. A brood of Hierophants are likely to be at the forefront of a major Tyranid planetary assault -- striding forward, drawing the enemy's heavy weapons fire away from the lesser Tyranid organisms, absorbing tremendous amounts of firepower before smashing into the enemy line with devastating force.

Like all Tyranid species, this Bio-Titan seems to be able to mutate rapidly, evolving new weapons and defences as required. The genetic process through which the Norn-Queen develops such unusually large biological constructs remains a mystery to the Imperium of Man's Magos Biologis. Whilst it seems that a Hive Tyrant or Carnifex could easily be a further adaptation of the basic genome and body plan of a Tyranid Warrior, no other known Tyranid bioforms are a logical precursor for the Hierophant. Combating a Bio-Titan like the Hierophant is simply a matter of applying the heaviest firepower available; large ordnance weapons and heavy artillery have so far proved the only effective weapons for Imperial forces in destroying the hideous Tyranid Bio-Titans.
