While Gohan has a tough fight, Son Goku and Ribrianne's battle continues. Ribrianne wants to win the "Tournament of Power" so that she can become a goddess beloved by humanity throughout all the universe, and she attacks Goku at full power.

With his unthinkably colossal ki, Jiren overwhelms Goku and the other warriors.
