Dragon Ball Kai • S01E96 : Combine Our Power! The Mightiest Final Kamehameha
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 the potential to destroy the entire solar system with this blast. Meanwhile, Vegeta apologises to Gohan for his recklessness. As Gohan and the others watch on in hopelessness, Goku contacts his son from the afterlife and tells him that even in his injured state he has the potential 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 overpowers Cell's wave, obliterating Cell's body and and saving the Earth from destruction. Gohan has won and the Cell Games are finally over.
