Gogeta puts both of his hands in front of him, palms open, hands turned up at a 90 degree angle and fuses together the vast energy of the Super Kamehameha Wave and the Big Bang Attack into a whitish-blue energy ball (releasing small/medium excess energy in the form of small waves radiating off of it) about the size of Gogeta himself. From this potent energy ball emits an intensely powerful, shockwave-like beam that damages the target severely, if not killing them outright.
The Big Bang Kamehameha is developed by Super Saiyan 4 Gogeta during his struggle with Omega Shenron, the product of Syn Shenron's absorption of the seven Dragon Balls. Its usage combines all of Gogeta's immense power into one concentrated sphere of ki, before being projected in the form of a large wave of energy.
- In the anime, Gogeta only uses this technique while in his Super Saiyan 4 transformation, but in Shin Budokai, and Buu's Fury, and Budokai Tenkaichi 3 he can use it in his base form as well.
