This power was from the Forbidden Knowledge of the Shadow Warrior section of the NinjaNomicon. Due to cutting corners, Randy, in "Dawn of the Driscoll", loses control of the ability, destroys part of the science lab, and accidentally brings Jerry Driscoll back to life. Following defeating Jerry and deciding he was too dangerous, Randy reverses the ability, returning Jerry back to a lifeless skeleton.
Randy later uses it again, and has apparently mastered it, in "Silent Punch, Deadly Punch", where he uses it to jump start the growth of the The Stunk Pine, from which the sap was used to make his smoke bombs.
- It's revealed in "Brolateral Damage", that the ability can be used to fix machinery.
