Gargoyle

Gargoyles are vicious winged monsters that are often the first part of Tyranid swarms seen in battle.Their prime purpose seems to be seeking out the enemy and sowing terror and confusion amongst them. Thus, fire and the flap of the Gargoyles membranous wings precede the Tyranid hordes, driving the enemy out into the open to be absorbed by the swarm. Gargoyles physically resemble Termagants, being derived from the Gaunt genus. They have wide, leathery wings, raking claws and barbed tails. Though they have six limbs, the lower pair have atrophied to little more than stumps.
