Is probably that he'll cut those thievin shape-shifters off in time to kill them. xD
However that's not really what it was about. More reminiscent than hoping to kill someone. I had to take a break and do something for myself a few days ago and I love drawing Nero.
Nero's a shape-shifter, this is his only other form other than his human self. He's just some sort of large dog (very large dog. lol.)
