Solar Kamehameha

Solar Kamehameha (太陽系破壊かめはめ波) is a Super Kamehameha technique and Super Perfect Cell's final and most powerful attack.

Overview
First, Cell stores up an immense amount of energy as he prepares a Super Kamehameha. He then brings his hands forward and fires a blast that Cell claims has enough power to wipe out the entirety of Earth's Solar System.

Cell uses this attack at the end of the Cell Games, against Super Saiyan 2 Gohan. Though Gohan counterattacks with the Father-Son Kamehameha, Cell overpowers Gohan several times during the Beam Struggle. However, as Cell is about to finish off Gohan, Vegeta distracts Cell with a huge ki blast. With Cell distracted, Gohan uses the brief window of opportunity to unleash all of his power, overpowering and completely annihilating the evil Bio-Android.
