Hello everyone, The following is continued research on a book my wife and I are writing. In said book our Heroine has enhanced speed and strength but during the final act of the book she is constrained to the limits of human strength. We have decided that she would be capable of the limits of what is humanly possible but not beyond. This leads to our final fight scene where she is fighting the arch villain. My wife would very much like for the Heroine to deliver the final blow by penetrating the Villain's Chest-bone but I have no idea if this is physically possible. Can this happen?
