Warpulator

The Warpulator, it makes its only appearance in Mario & Luigi: Partners in Time in which it is possessed by Stuffwell, another invention of E. Gadd. The Warpulator has the power to reverse the flow of time and send individuals to an predestined point, bringing with them all their current inventory and stats. The Warpulator is only used near the climax of the game, where the Mario brothers are trapped in a point of no return and must face battle with Princess Shroob, so they can go back and do any tasks they might have missed. It can also be used after the elder Princess Shroob was defeated, at the price of reversing the victory over the Shroob empire.
