Nice. I roll natural 20. "You charge the Shyfter and punch right through his chest. Your hand wraps around his spine and you rip it clean out of his body!
Blood and gore spray everywhere as you hold the spine triumphantly over your head. The Shyfter is dead! You are victorious."
I say "FATALITY!!!" And by the way, I will become DM after you, for I am already "THE LORD OF DUNGEON MASTERS". At least according to my friends. PS. They're D&D noobs.
