Even Stronger! Goku's Dream is Never-Ending! (もっと強く！悟空の夢は終わらない！！ Motto Tsuyoku!! Gokū no Yume wa Owaranai) is the one hundred sixty-seventh and final episode of Dragon Ball Z Kai. Its Japanese air date is June 28, 2015.
Goku and Uub begin to fight, and it is clear that Uub does not know much about fighting. But as the match goes on, he grows more and more accustomed to his hidden power, and it is finally released, so he is able to go toe-to-toe with Goku in his base state. When Goku does power up slightly, Uub nearly falls out of the ring, but Goku saves him from hitting the ground. He realizes that Uub doesn't even know how to fly, so Goku decides to train him. Despite his friends and family pleading with Goku to stay, he flies away with Uub on his back. Goku decides to train Uub to defend the Earth when he's gone. He hopes one day, when Uub's training is complete, to have a real all-out match with him, to test their power. Goku and Uub fly off into the distance, with whoops of joy.
