Staple

Staple is an option in Completing the Mission during the final choice screen for the "Revenged" pathway.

After defeating the Right Hand Man in combat, Henry Stickmin captures Reginald Copperbottom and has to choose how to have his revenge against him. When Staple is chosen, Henry pins Reginald to the wall of the cockpit of the Airship, which is about to crash into the Toppat Launch Site. This way, the crash will kill Reginald. Before Henry can leave, Reginald takes a hidden gun from his hat and shoots Henry in the back, crippling him, so both men are forced to stay in the airship as it crashes.

Both survive the crash, with Reginald still being pinned to the wreckage of the Airship, but die soon after.
