A flying Hive Tyrant with enormous wings and a colossal specialized cannon suddenly swooped into the battlefield at low altitude. The shadow the behemoth cast in flight was even larger than a Tyranid Sky Demon's.
Flying Hive Tyrant (I couldn't find an image of the modified weapon component. Look it up on Baidu yourselves.)
It was also equipped with an enormous cannon glowing with intense green bioluminescence.
Some of the warriors below quickly recognized this unusual weapon.
It was a specialized Tyranid weapon known as the Miasma Cannon.
Of all the symbiotic weapons used by the Tyranids, none was more terrifying than the Miasma Cannon.
Unlike other Venom Cannons, this symbiotic weapon fired viscous toxins so corrosive that they could reduce prey to an unrecognizable organic sludge within seconds.
The flying Hive Tyrant's head was also unusual.
Its enormous biological structure was in a strange, partially exposed state.
An unusual parasitic organism called the Norn Crown enveloped the Tyrant's hideous skull.
This bizarre parasite had been discovered and named by Inquisitor Kryptman.
The grotesque organism used dozens of tendrils to coil around and attach itself to the top of its Tyranid host's head.
The Norn Crown could connect directly to its host's brain and spread the hive mind's will through it, extending a synapse creature's control range or greatly amplifying its psychic abilities.
The moment this doubly enhanced flying Hive Tyrant appeared on the battlefield, its psychic shrieks disrupted the defenders' communications and minds.
Its powerful psychic energy could even deflect incoming fire.
Every shot from the enormous biological weapon bonded to its body engulfed an entire area in acid.
Even Astartes and mortals wearing Power Armour struggled to survive such powerful acid.
Besides this enormous flying Hive Tyrant, large numbers of Hive Guard with thick carapaces and formidable defenses
