Toxicrene
The Toxicrene is a monstrous Tyranid designed as a more offense-minded Venomthrope. Spotting a dozen Lash Whips all filled to the brim with a hideously effective poison (2+ AP2) it is quite effective at dealing with tough enemies. Its model is very large: the massive tentacles make the Toxicrene nearly three times as wide and one and a half times as long, encouraging the use of pinning to be able to remove the tentacles while in transport.
On the tabletop the Toxicrene is an odd beast: while its hits are almost sure to wound hitting is a bit of a problem with its low WS and not to high number of attacks, making it unlikely for you to wipe out a squad of Terminators in one round. It also possesses an odd shooting attack in the form of a 12" S3 AP- Poisoned 2+ Large Blast, with the added bonus of having Armorbane on damaged or open-topped vehicles. The downside is that while Armorbane is useful, at the end of the day 3+2D6 is only an average of 10, with 14 being extremely rare to even TOUCH the likes of a Land Raider. As such, this shooting attack is best not relied upon. At least it doesn't suffer from the creature's average BS like with its brother, the Maleceptor.
The Toxicrene is effective at fighting and stalling powerful Monstrous Creatures like Wraithknights and Riptides, but it is best kept away from enemy vehicles because of its modest strength in favor of a Carnifex.
