Dende heals Krillin's injuries. Krillin is then able to distract Frieza long enough for Dende to heal Gohan. Though they are both back to full strength, it all seems useless, because none of them are a match for Frieza. Suddenly, Piccolo finally arrives at the scene. He tells them that he will take on Frieza alone. Krillin and Gohan don't understand why he would do this, but Piccolo insists. With his new strength acquired from fusion, he is confident that he can take down Frieza.
