From the introduction:
The Tournament of Power, a tournament which Zen-Oh arranged, was one in which the greatest fighters from the different universes fought desperately for survival. After a lengthy series of battles it ultimately came down to a single winner, Android 17. Although he had been able to slip into entering under the guise of appearing to be a human, 17 and 18 were not of a species that were originally robotic in nature, and had been artificially enhanced through science. As this was brought up, Zen-oh was initially displeased and meant to destroy Universe 7, until an idea occurred to the Future Timeline Zen-Oh.
