DB Episode 98
From Dragon Ball Encyclopedia, the ''Dragon Ball'' wiki
Tien grabs Goku and uses his Volleyball Attack on him. He spikes Goku down into the ground, but to his surprise, Goku gets up. He says that throughout the tournament, he had only been using a fraction of his strength to protect his opponent, but now he is going to fight at full power. He unleashes a brutal assault on Tien, then starts conjuring a Kamehameha wave, but stops, realizing Tien would have dodged it. Tien meditates briefly, then they continue the match. Goku's next assault nearly pushes Tien out of the ring, but Tien is able to counter it. Goku then creates ten afterimages of himself to confuse Tien. When Tien attacks one of the false images, Goku sneaks up and knocks him down. Tien uses his Solar Flare technique, but Goku borrows Master Roshi's glasses and counters with his own attack. Goku jumps up for an attack, but is mysteriously frozen, allowing Tien to knock him down.
