Hierophant

Hierophants (Gothic: Tyranicus giganticus) are a type of colossal Tyranid bio-titan which feature in Games Workshop's Warhammer 40,000 universe.

Description
Enormous organic weapons many dozens of metres in height and weighing upwards of fifty tonnes, Hierophants are amongst the largest Tyranid land-based constructs encountered by the Imperium of Man to date. Heavily armoured monstrosities which stalk the battlefield on four spiny legs, they are commonly equipped with a pair of powerful bio-cannon for long-range work or mighty pincers and scything claws for dealing with armoured opponents up-close. In addition to this terrifying armament, they feature a cluster of venomous tendrils which hang from the underbelly, used to ensnare and crush the life from any infantry unfortunate enough to come within their reach, and and constantly emit a cloud of toxic spores, lethal to any unprotected living creatures which venture too close.

Battlefield Role
Hierophants are deployed at the forefront of any major Tyranid land-based offensive, with groups of these creatures used as demoralising linebreakers to crush any enemy armoured formations, dug-in troops, or fortifications which stand in their way. Their mere presence on the battlefield is a powerful psychological weapon in itself (something the Tyranids are extremely good at exploiting) with the only sure-fire way to deal with a Hierophant being the focused and sustained application of heavy ordnance.
