Otherwise known as the '''Wrecking Ball''' or '''Stone Crusher'''. The Stone-Crusher is a Tyranid close combat Biomorph most commonly encountered on the Stone-Crusher Carnifex and is nothing more than a large mass of bone, chitin and flesh. Designed for urban battles, the Stone-Crusher is rammed through a wall using the Carnifex's immense strength then pulled backwards to wrench the entire structure down.

In 7th Edition, Stone Crushers turn a Carnifex into a living battering ram. Wrecker Claw and Bio-Flail replaces their ability to re-roll amour penetration on their regular attacks with the ability to cause Instant Death and gain a new rule, Sweep Attack. Sweep Attack allows a model to replace all their attacks with a number of attacks equal to the number of enemy models in base contact with them. This allows a Stone Crusher Carnifex with a Wrecker Claw and Bio-Flail to generate more attacks and stops it being tarpitted as easily, while the trade off is that they may find it harder to destroy vehicles.
