The Return of Goku
Nappa defeats Krillin and fires a massive power blast to finish off Gohan. Piccolo saves Gohan by sacrificing himself, but this also sacrifices Kami and the seven Dragon Balls necessary to wish everyone back alive! Gohan is enraged and uses all of his power to avenge Piccolo, but Nappa is too strong. Luckily for Gohan, Goku finally shows up!
