#2 Package Piledrive
Similar to a piledriver from which it takes its name, the Package Piledriver ups the ante by entangling its victim's limbs to prevent any chance to lessen its impact. While the man who made the move famous to western audiences--Kevin Owens--always performed the move safely, it is still considered too dangerous for the mainstream wrestling product.
Why the move was banned: Like all piledrivers, the move involves a straight down drop on the opponent's head. While the executor is supposed to protect the recipient, the stakes for an accident are simply too high for major wrestling companies to allow it.

Where the move is banned: The WWE forbade Kevin Owens from using the move, forcing him to switch to the Popup Powerbomb instead. ROH allows the move but only for certain competitors.
