Wu Ren transmigrated into the world of Dragon Ball and became a Saiyan, but one from Universe 6, a universe destined to lose the Tournament of Power.
The Tournament of Power is a survival contest where eight universes each send ten fighters. The losing universes will be erased completely, and as a transmigrator, Wu Ren won't be able to bring them back either.
And his opponents in the tournament include a Super Saiyan God and someone on par with a God of Destruction...
His teammates: three complete clowns, two troublesome girls, two green-skinned nobodies, and a traitor. Wu Ren can only cry out that they're impossible to carry.
Fortunately, he still has the chance to temporarily travel to other worlds. If he can't find capable teammates in Universe 6, he'll recruit them from other universes.
Wu Ren will lead people from different universes, each with different powers, into the Tournament of Power and lead a rebellion against the King of the entire universe.
