Big Bang Kamehameha
From Dragon Ball Encyclopedia, the ''Dragon Ball'' wiki
The Big Bang Kamehameha (ビッグ バン かめはめ波, Biggu Ban Kamehameha) is a combination of the Super Kamehameha and Big Bang Attack used by Gogeta as his most powerful technique in his Super Saiyan 4 form. Gogeta puts both of his hands in front of him, palms open and hands turned up at a 90 degree angle. Then, he fuses together the huge energy of the Super Kamehameha and the Big Bang Attack into a large whitish-blue energy sphere with medium excess energy in the form of small waves radiating off of it. From this energy sphere emits an extremely powerful, shockwave-like beam that damages the target severely, if not killing them outright.
Gogeta uses this attack in his battle against Omega Shen Long, the product of Syn Shen Long's absorption of the seven Dragon Balls. After turning Omega Shenron's Negative Karma Ball into a positive blue energy sphere, Gogeta fires the Big Bang Kamehameha at the Shadow Dragon, seemingly killing him. However, Omega survives, but the attack was so great, it causes Omega Shenron to regurgitate all of the Dragon Balls, reverting him back to Syn Shenron. Gogeta tries to use the Big Bang Kamehameha again to finish off Syn Shenron, but because of the tremendous power he possesses, Gogeta defuses ten minutes later back into Goku and Vegeta before he can launch the finishing blow.
In some video games (ex. Dragon Ball Z: Budokai Tenkaichi), Gogeta's ultimate attack is the 100x Big Bang Kamehameha, a much more powerful version of the move, dealing an extremely high amount of damage.
- In the anime, Gogeta only uses this technique while in his Super Saiyan 4 transformation, but in Dragon Ball Z: Shin Budokai, Buu's Fury, Dragon Ball Z: Budokai Tenkaichi 3, Dragon Ball: Raging Blast, and Dragon Ball Z: Ultimate Tenkaichi, he can use it in his Super Saiyan form as well.
- Though the attack is a hybrid of the Big Bang Attack and Super Kamehameha, it is fired with a somewhat similar stance to the Final Flash, though this may be because the stances used to perform the attack are a combination of the Big Bang Attack and the Kamehameha's (hands in front of user = Big Bang Attack; two-handed fire = Kamehameha).
- In Budokai Tenkaichi 3, this attack is the only Blast 2 attack that can travel through a Super Explosive Wave and harm the person using it. In fact, Big Bang Kamehameha, Gohan's Father-Son Kamehameha and Bros. Kamehameha, Super Vegito's Final Kamehameha, and Super Perfect Cell's Solar Kamehameha are the only Kamehameha waves that are strong enough to pass through Super Explosive Waves.
- This move appeared in Buu's Fury as one of Gogeta's attacks, despite the fact that it first appeared in Dragon Ball GT (in the episode, "Super Saiyan 4 Fusion").
