The Kryptonite Krunch, also known as an over the shoulder back-to-belly piledriver, begins with the wrestler facing his opponent. From there, the wrestler will pick up the opponent and place them over his / her shoulder so that the opponent's head is dangling over the wrestler's back by the waist of the wrestler. The wrestler then holds the opponent in place by holding his / her leg with one arm and applies a headlock to the opponent with his / her other arm. The opponent is now bent into a circle. The wrestler then drops to a seated position, driving the head of the opponent into the ground.
The move was utilized nationally across the United States most often under the name Kryptonite Krunch by Nova, although it has been done for years under many other names like the Reality Check as used by Michael Modest and the Schwein as used by CIMA.
Another method used when performing this over the shoulder piledriver sees the attacking wrestler lift the opponent over one shoulder but bring him / her across the wrestler's back and place the opponent's head under the other arm. This version is best known as Mariko Yoshida's Air Raid Crash, a name which is often wrongly used when referring to the Kryptonite Krunch. Colt Cabana uses a neckbreaker variation of the position of the Air Raid Crash where he drops down to a kneeling position, and lands the opponent onto his knee. Finlay uses a running variation called the Celtic Cross.
