Raveners

The Ravener (Tyranicus ophidius subterra) is a Tyranid bioform that is a variant of the standard Tyranid Warrior specialised for assault. It is capable of digging underground to launch surprise ambushes upon unsuspecting foes from beneath their own feet. Imperial Magi Biologis researchers believe that the Ravener is a variant of the Tyranid Warrior genus. The same savants hold that other Tyranid creatures, such as the Trygon or Haruspex, may in turn descend from the Ravener genus.
