Red Terror
From Warhammer 40k - Lexicanum
The Red Terror was a particularly large and deadly Tyranid Ravener, armed with sets of great scythe blades. It is only recorded as being encountered once by the Imperium, where it gained the name of "Red Terror". During the Tyranid invasion of Devlan, an Imperial mining world on the Eastern Fringe, it tore into a starport compound to get to its defenders, killing twenty four men before being driven away. Each time it returned it slaughtered more humans before retreating back into the tunnel, devouring the rendered human remains. Eventually a search and destroy team was sent into the tunnels, only to meet their doom at the scythes of the Red Terror.
