The tournament grounds buzz with activity as the World Martial Arts Tournament is about to begin, and even Mr Satan appears. The Junior Division begins and it is Trunks' turn. Being unmoved by his unlikable opponent's taunts, Trunks easily wins. Eventually it is Goten's turn, and although he is nervous to be in the ring, Goten easily wins as well. The two squirts with Saiyan blood advance along nicely, and just as expected, the Junior Division finals ends up being a fight between Goten and Trunks. Once it begins, the match becomes a super fierce battle that surpasses reason, and the audience is astonished. The two continue their even battle, with neither giving an inch. Trunks fires a Double Buster, and not to be outdone, Goten launches a Kamekameha. Finally put in a pinch during the intense battle, Goten unthinkingly becomes a Super Saiyan. Full of confidence, Trunks pushes back Goten's attack and becomes a Super Saiyan as well. During this dangerous offensive and defensive match, Goten's legs touch the spectator seats, and loses through an out of bounds. Trunks is confirmed as the champion.
