Best of the Boys (うれしさ百万倍!少年王者決定!!, Ureshisa Hyakumanbai! Shonen Chanpion Kettei!!) is the third episode of the World Tournament Saga and the two hundred twelfth overall episode in the original dubbed and the uncut Dragon Ball Z series. The episode first aired on January 12, 1994. Its original American air date was October 3, 2001.
The episode starts as Trunks and Goten start the final round of the junior division. Mr. Satan stares at the two, saying that the boys are like the ones in the Cell Games seven years ago. The two start to float in the air. Trunks and Goten land on the stadium floor. Trunks fires a Double Buster blast at Goten. He misses and the blast is controlled up. Goten uses a Kamekameha blast at Trunks that blasts a hole in the roof, impressing Trunks. They start fighting again but Trunks asks "Goten, no more energy blasts, okay?" and Goten agrees.
The two get each other in a strangle hold but Trunks is stronger. He wants Goten to give up, no dice. Instead, Goten goes Super Saiyan breaking the hold. Goku is amazed that his second son can go Super Saiyan at his age. Vegeta tells Goku that was not fair. The people do not know what they saw. Mr. Satan is stunned that the kid can do what Goku, Future Trunks, Vegeta, and then 11 year-old Gohan can do. Trunks is enraged and says that he can beat Goten without his left arm. The battle rages on. The two fight until Trunks shoots another beam at Goten which misses. The two fight until Goten tries to headbutt Trunks but he dodges and goes Super Saiyan and hits Goten with a left-handed energy sphere. Goten is thrown into the stands and loses the fight. Trunks wins the 1 million Zeni and Goten wins 500,000 and Bulma cheers for Trunks' victory. Goten is angry that Trunks used his left hand even though he said he wouldn't, but Trunks bribes him with the offer of three free toys.
Trunks now faces Mr. Satan, who is too afraid to come out but does after his fans cheer for him. After Satan comes out, Vegeta makes a joke: he says that house plants are stronger than Mr. Satan, which Gohan tries to pass off as a joke, not an insult to Videl.
