#4 Killswitch/Unprettier
The Killswitch or Unprettier is a move that was popularized by former WWE World Champion Christian. The move which is technically known as the inverted double underhook facebuster involves grabbing the arms of an opponent from their behind and then maneuvering themselves in front of the opponent. This puts the opponent in a position where his/her face faces the ground and the person applying the move drops onto their back which drives their opponent's face into the mat.

The opponent doesn't have an option to break themselves free of the hold while falling down and often bump their head into the mat. Current WWE Superstars Tyler Breeze and Chelsea Green uses the same move and calls it the Unprettier and I'm Prettier respectively. NJPW wrestler Juice Robinson uses a variation of this move and calls it Pulp Friction.
#3 Skull Crushing Finale
The Skull Crushing Finale is a finishing move that has been popularized by WWE Superstar The Miz and like the Killswitch in the previous point, is another form of the facebuster move. The move involves The Miz trapping his opponent's head in a full nelson hold and then sees him performing a leg sweep that allows him to slam his opponent face-first into the mat.
It is a simple and easy move to set up but it takes a lot on The Miz's part so as to not injure his opponent as they cannot protect their face with their hands as The A-Lister keeps them trapped with the full nelson hold. If applied without much caution, the Skull Crushing Finale can legitimately hurt a wrestler's face.
