Hell Hound

So on Wednesday night I went to the greyhounds, and ever since then I've been wondering what name I'd give to a greyhound if I ever bought one to race.

I'd want its name to be a symbol of power and dominance.
A name that when spoken aloud forces all other dogs to stop in their tracks and cower.
A name that will cause men to stand still, fear will seize them, for they know if they run they will be dragged down from behind and devoured by my greyhound as if it were a hound straight from the depths of hell.

So what kind of name could induce this kind of reaction?????

I was think of something along the lines of 'Harbinger'

Yes.....a sign of things to come.
