A Hero's Sacrifice! Last Chance to Save the World!.In a desperate attempt to destroy Earth, Cell begins to self-destruct. With mere seconds left, Goku says goodbye to everyone and his son and teleports himself and Cell to King Kai's planet, the only safe place he could think of. Upon arrival, Cell finally explodes, destroying the planet and killing everyone there. As Gohan and the rest of the Z Fighters are left on Earth to grieve, Goku and King Kai realize that Cell hasn't accompanied them to the Other World, and therefore must have survived the explosion. Using Goku's Instant Transmission technique, Cell returns to Earth, where he kills Trunks with a single blast through the chest, using his Full Power Death Beam. Cell then reveals that not only did his nucleus survive the explosion, but he was able to regenerate into his Perfect Form - and thanks to his Saiyan genetics, he is far stronger than ever before (Cell's Super Perfect Form). Enraged by the death of his son, Vegeta unleashes a furious barrage of ki blasts at Cell, but is easily defeated, and is only saved from certain death when Gohan intercepts Cell's blast and takes the full force of the attack. With Gohan injured and his left arm broken, and nobody left to challenge Cell, Cell prepares one final Kamehameha to destroy Gohan and the Earth once and for all.
