Summary
Goku hits Frieza with the Kaio-Ken x 20
Captain Ginyu tries to steal Piccolo's body, but is foiled by Gohan who throws the frog body back in the way, restoring he and Bulma back to the way they were. Meanwhile, Goku continues to be thrashed by Frieza. However, he sees a vision of how Frieza could destroy everyone he loves - and as a result, he uses the 20x Kaio-ken alongside a massive Kamehameha wave against Frieza. However, even this is not enough to defeat the tyrant, and the use of the 20x Kaio-ken severely weakens Goku. He then has another vision, this time of Vegeta and other Saiyans of the past, including his father Bardock. Motivated once again, he gets back on his feet as Frieza lunges at him.
Error
