Time machine

A time machine is a fictional device used in many science fiction franchises that allows the user or users to travel back in time, or into the future.

In Back to and from the Future, a time machine appears at William Missionima's door. He uses it to travel back and forward in time.

In Movin' In (Anthony's Song), Teddy and Anthony build a time machine in the control room of the Missionima House. As a result of the control room, Armos sneaks in and attempts to blow the house up. William uses the time machine to make sure Anthony never moved in, thus he couldn't build the control room, and Armos never came to blow the house up.
