"I'll send you to the next world with this, times one hundred!"
100x Big Bang Kamehameha (100倍ビッグバンかめはめ波), also known as Full-Power Big Bang Kamehameha (全力ビッグバンかめはめ波) or Ultra Big Bang Kamehameha (ウルトラビッグバンかめはめ波) in Dragon Ball Heroes is a full-powered version of the Big Bang Kamehameha, used by Gogeta in his Super Saiyan 4 form.
To perform the technique, Gogeta puts his hands in front of him like the normal Big Bang Kamehameha, but charges it with much more power. Then, he fires a huge streaming energy wave at the opponent, inflicting a massive amount of damage. In Dragon Ball Heroes, it is performed differently, he puts his hands together creating a blue aura, then he stretches his hands on the side, expanding the whitish blue aura into a long beam, then turning it into a huge purple blue energy wave before putting in front of him, condensing and firing it.
