A creature from Dan Simmon's Hyperion series of books. Frequently described as a walking exacto-knife. Stands 3 meters tall. Covered in an indestructable chrome coating. There is not a place on his body that is not sharp or extremely dangerous. Created far in the future, it is a technological marvel even for the year 3200AD.

Capable of moving through time as easily as we walk down the street.

Also known as the Lord of Pain.
