Dragon Ball Kai

Synopsis

Super Perfect Cell continues to charge his Kamehameha, and reveals that not only has he gathered enough energy to destroy the Earth, but he also now has enough power to destroy the entire solar system with this blast. Cell also reveals that he will be able to use Instant Transmission to teleport away to safety before the blast detonates, allowing him to escape the Earth's destruction unscathed. Meanwhile, Vegeta apologizes to Gohan for his recklessness. As Gohan and the others watch on hopelessly, Goku contacts his son from the Other World via King Kai's telepathy and tells him that even in his injured state he has enough power to defeat Cell. Reinvigorated, Gohan prepares a final, one-handed Kamehameha to repel Cell's blast. As the two warriors struggle to overpower each other, Piccolo, Tien, Yamcha, and Krillin bombard Cell with ki blasts in a knowingly futile attempt to help, but are easily repelled. As Goku coaxes Gohan to release his full power against Cell, Vegeta returns to the battlefield and launches one final Big Bang Attack, which temporarily distracts Cell. Seeing the opportunity, Gohan finally releases his full strength and is able to overpower Cell's blast, obliterating Cell and saving the Earth from destruction. Gohan has won and the Cell Games are finally over.
