During the Tournament of Time in Age 780 of the main timeline, a team of Cells consisting of Imperfect Cell, Semi-Perfect Cell, and Perfect Cell appear as Tournament of Time participants. In Part 12, while Goku (present era), UltimateGohan (Fusion Saga), and Hit (present era) are searching for members of the Mastermind's group in order to locate the dimension where Zahha is hiding, they come across the Cells. Unfortunately after defeating them, they realize that the Cells were just Tournament of Time participants unconnected to the Mastermind's group.
