|Inventor/Creator||Unnamed 12th Universe Mortal|
The Time Machine is a device created by an unknown mortal of the 12th Universe, that allows the user to travel to the past, which in doing so creates a time ring.
Upon the machine being created, the inventor ended up creating a parallel world, leading to the manipulation and altering of time to be strictly forbidden. It eventually fell into the hands of Agu, and when Zamasu sought out the Kaiōshin's life, discovered it and took it for himself, who intended to use it to complete the Zero Mortals Plan.
