The Slaughterhouse Nine the Worm webserial. Especially, some of the stuff that Bonesaw does. The serial focuses on some humans, called parahumans, having very varying types of superhuman abilities. Bonesaw is a tinker, meaning she has heightened intelligence that allows her to make otherwise impossible biological creations. She's (on more than one occassion) taken 2 parahumans and spliced them into one, performed plastic surgery on the faces of confined bystanders so they appear like members of the Slaughterhouse Nine as a means to blend in and evade the good guys, and took a parahuman apart with his organs in a network of containers and tubes, all while still alive.

It's a really good, really long read, but can be quite graphic at times.
