#4 The Piledriver
An interesting fact about this move is that the Piledriver was created as a total accident. Its creator was Toshiaki Kawada, who attempted to powerbomb his opponent, Mitsuharu Misawa, but he failed in doing so.
Misawa kept countering Kawada’s powerbomb by not allowing himself to be lifted in the air. Eventually Misawa relented, but again tried to counter Kawada’s power bomb while in the air with a Hurricarana. Kawada, unaware of the counter, slammed Misawa on the back of his neck. The audience appeared stunned, which obviously was good enough for Kawada to use it a few times more in the future.
Stone Cold’s career was shortened due to a neck injury he suffered at the hands of Owen Hart and a Piledriver. The move is seen as so dangerous, it has permanently been banned from the WWE.
