Trygons

A Trygon is a species of Tyranid that is similar to the smaller Ravener and often leads their hordes 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. It is also a very good stealth operative for the Tyranids, popping up behind enemies and slaughtering them where they stand.
