"A Crucial, Honorable Match! Gokū versus Tenron" (いざ御前試合！悟空ＶＳ天龍, Iza Gozen Shiai! Gokū Tai Tenron; FUNimation "Goku vs. Sky Dragon") is the eightieth episode of the Dragon Ball anime.
Gokū makes an enduring journey to challenge Chin Taiken. Taiken is busy fending off Shaolong and his two men. Before Shaolong can begin a fight, his brother Tenlong stops him. Taiken agrees to work out with Gokū, his son Shōken getting worried. Gokū finds Taiken has been in weak health lately and learns from him about the King's Tournament. Gokū manages to get medicine for Taiken, managing to avoid conflict with the Long brothers. Tenlong spends his time terrifying his students. Gokū volunteers to take Taiken's place in the King's Tournament. Jealous Shōken spikes Gokū's breakfast. At the tournament Gokū is battling Tenlong as the laxative kicks in, but he resists the effect and beats Tenlong. The Long brothers and students join Taiken for his teachings and Gokū resumes his journey.
