Trump Card (超特大の元気玉 これが最後の切り札だ!!, Cho Tokudai no Genki Dama Kore ga Saikyo no Kirifuda da!!) is the seventeenth episode of the Frieza Saga and the ninety-second overall episode in the uncut Dragon Ball Z series. The episode first aired on May 29, 1991. Its original American air date was October 13, 1999.
Goku's Kaio-ken Kamehameha does nothing more than singe Frieza's palm and leave Goku tired out. Gohan, Krillin and Piccolo notice this from afar, and in dark glee, Piccolo remembers King Kai's advice to stay away from Frieza at all costs. Elsewhere, Bulma and Captain Ginyu recover from having been blown away by Frieza's attack. Bulma then recaps on what just happened to her when Ginyu stole her body. She sees Ginyu, still in a Namekian Frog body, struggling to push off a rock that is on him. She grabs him by the tail and playfully scolds Ginyu for his treachery.
Frieza resumes his attack on Goku and dominates the worn out Saiyan completely. As Goku begins to realize that he cannot defeat Frieza, he has another vision, this time of Vegeta, who reminds Goku of his promise to defeat Frieza and avenge the Saiyans he has killed. King Vegeta and Bardock also appear, and the three implore him one last time to stand up to the tyrant. After the vision fades, Goku furiously fights back but is quickly struck back down. Frieza begins hitting Goku with Death Beams. Goku takes all this stubbornly, and eventually raises his arms to prepare a final attack, with Frieza ignorantly believes this to be a sign of surrender. Krillin, Gohan and Piccolo, however, realize Goku's intention, and see a Spirit Bomb growing in the sky.
