The '''Toxicrene''' is a species of [[Tyranid]] specializing in biological warfare.{{Fn|1}}

Physically imposing, the Toxicrene accompanies Tyranid broods into battle and uses its toxic{{Fn|5}} tentacles to thrash at those who venture too close. However, its most feared weapon is the choking clouds of spores that blast out from its dorsal chimneys. Each cloud is composed of millions of tiny spore organisms that possess a predatory sentience, deliberately forcing themselves into the respiratory systems of non-Tyranid organisms. There they nestle and embed, feeding on the moisture of their host and growing at astonishing rate, causing organs to rupture, airways to close, and lungs to fill with blood.{{Fn|1}}

[[Hive Fleet Gorgon]] in particular is notable for its extensive use of Toxicrenes in the opening stages of battle, relying on the dense clouds pumped out by the creatures to mask its advancing swarms and wear down enemy defenders.{{Fn|2}}
