La tactique secrète

The battle between Goku and Cell continues to heat up. Both of them seem to have even strength and speed. After Goku nearly falls out of the ring, Cell decides to destroy the ring and continue the fight with no rules. With nothing restricting them, the battle quickly intensifies, and as they fight, their power seems to increase. As they fight on, Goku decides to attempt to trick Cell by preparing a Kamehameha wave from up in the air. Cell doesn't believe that Goku would risk destroying the Earth, and so does nothing to defend himself. As the other fighters look on in horror, believing that Goku will release it from the air, Goku uses his Instant Transmission technique, and appears directly beneath Cell. He unleashes the wave directly into Cell's chest, and when the dust clears, Cell is severely maimed. It appears that Goku has won the tournament. (Source: Wikipedia)
