The Solar Kamehameha is Super Perfect Cell's final and most powerful attack he used at the end of the Cell Games. Super Perfect Cell stores up an enormous amount of energy for the attack and launches it into a huge and very powerful Kamehameha that has enough power to destroy the Earth along with the whole Solar System.
Super Perfect Cell tried to use it as a final attack to kill SSJ2 Gohan, who counterattacked with the Father-Son Kamehameha. During the Kamehameha duel, Super Perfect Cell overpowered Gohan several times due to the android breaking the young Saiyan's arm with a ki blast. However, as Super Perfect Cell was about to finish off Gohan, Vegeta distracted Super Perfect Cell with a Big Bang Attack. With Super Perfect Cell caught off-guard, Gohan used all of his power to completely annihilate the evil android.The attack was named in Dragon Ball Z: Budokai Tenkaichi 3 and is Super Perfect Cell's Ultimate Blast.
