Trygon

A Trygon is a species of Tyranid that is similar to the smaller Revener and often leads them into battle. It creates huge burrows to tunnel behind enemy lines and uses its acute senses to detect the prescence of enemies above it. It is a deadly close combat specialist making use of six clawed arms, razor sharp teeth and a bio-electric field that flows through its armour and can incapacitate attacking enemies.
