A man was not two feet behind her, tall and brutish, his face badly scarred and battered to the point that it was barely recognizable as human.  A long-handled axe sat in one of his massive, calloused hands, the head resting on the floor.  Hatchet Face.

...

How?  How had he gotten there so fast?  She turned around and saw he was still there, still in the hallway.

There were two Hatchet Faces?

Then the first one exploded into a cloud of white dust and blood spatters, momentarily filling the room.  Amy could hear Bonesaw’s giggling, felt her heart sink.

“Get it?  You figure out what I did?  Turn around, Hack Job.”

Amy had figured it out, but Bonesaw’s creation demonstrated anyways.  He turned his back to Amy, and she saw what looked like a tumorous growth on the back of his head, shoulders and arms.  Except the growth had a face, vaguely Asian in features, and the lumps inside the growth each roughly corresponded with organs and skeletal structure.  The jaw of the figure that was attached to the back of Hatchet Face’s body was working open and closed like a fish gasping for air.  The stitches were still fresh.

“You mashed them together.  Oni Lee and Hatchet Face.”

“Yes!  I can’t even begin to tell you how hard it was.  I mean, I had to conduct the operation from a remote location, using robots, because I would lose my Tinker powers if I got too close to the big lug.  And I had to fit their bodies and nervous systems together so that they could use their powers without messing up the other.”

...

“Had to add in a control frame and perform a spot lobotomy so Hatchet would obey me, you know.  He didn’t lose much.  Was never very bright.”

“And Oni Lee?” Amy was almost afraid to ask.

“Oh, I barely touched his brain.  He suffered some moderate brain damage from his close brush with death, but I revived him.  His brain’s more or less intact, even.  He can’t control his body, but he’s alert and aware, and he feels everything Hatchet does,” Bonesaw smiled wider.

...

Hack Job flickered into existence just in front of Amy, and there was little she could do to escape.  She cried out as the man’s massive hand smashed her down onto her back, a few feet from Mark.
