Antagonist nick name

So I'm creating an antagonist for a sci fi idea, a serial killer with superhuman strength given through advanced surgical enchancements, and I need help giving him a name that would, in-universe, be given by the press. The killer is known for their trademark in which they rip through their victims' bodies and I was wondering if anyone had suggestions, such as an animal known for such habits or something catchy, for a name which referred to this activity. Thanks for any given help.

How about "The Rip Reaper"?

"The Sunderer?"

Alternatives to "rip" could be nice, like "The Shredder".

Butcher Pete

The Land Shark, The Grizzly Bear, The Tazmanian Devil

"The Butcher" is always a classic if not uncommon. Give him a name like "The Greenway Butcher" to reflect his comfort zone and the location of the murders. "New Jack" (or "Nu Jack" for a more Sci-Fi feel) could work as a reference to "Jack the Ripper". "Sloppy Joe" would work for a story for a comedic bent and would also work as a reference to which he leaves the state of his victims...

Thanks for all the suggestions everyone. I've to go with the name: "Whitechapel Weller" with the "Whitechapel" coming from the location of the Jack The Ripper killings and "Weller", taken from the Dickensian "Sam Weller" (http://en.wikipedia.org/wiki/Sam_Weller_(fictional_character), due to the fact that at each murder scene a male victim is also found, with a cause of death more efficient than the more brutal murders and without any evidence of having committed the crime themselves, and it is believed that "Whitechapel Weller" uses these men as accomplices and then disposes of them.
