"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 Hyakūbai Biggu Ban Kamehameha, lit. "100-Fold Big Bang Turtle Destruction Wave" or "100-Fold Big Bang Turtle Devastation Wave"), also known as Full-Power Big Bang Kamehameha (全力ビッグバンかめはめ波 Zenryoku Biggu Ban Kamehameha, lit. "Full-Power Big Bang Turtle Destruction Wave" or "Full-Power Big Bang Turtle Devastation Wave") or Ultra Big Bang Kamehameha (ウルトラビッグバンかめはめ波 Urutora Biggu Ban Kamehameha, lit. "Ultra Big Bang Turtle Destruction Wave" or "Ultra Big Bang Turtle Devastation Wave") 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.
Appearance in games
100x Big Bang Kamehameha first appeared as Super Saiyan 4 Gogeta's ultimate attack in Dragon Ball Z: Budokai 3 and has appeared in several video games since, Dragon Ball Z: Infinite World, the Budokai Tenkaichi series, Dragon Ball Heroes, and Dragon Ball Xenoverse. In most games is capable of inflicting major damage to the stage of play. With a few exceptions to which map is being played, whenever Gogeta uses the 100x Big Bang Kamehameha, it completely changes the stage to Ruined Earth or Dying Namek.
In Dragon Ball Z: Ultimate Tenkaichi, the technique is called Full-Power Big Bang Kamehameha (全力ビッグバンかめはめ波) and has a reddish-orange color.
In Dragon Ball Xenoverse, it appears under the name X 100 Big Bang Kamehameha and is Super Saiyan 4 Gogeta's Ultimate Skill. It can also be obtained by the Future Warrior as a reward in Parallel Quest 54: "Saiyan Warriors". In Xenoverse and Xenoverse 2, if the user is not locked-on to an opponent before performing it then they will sweep the X 100 Big Bang Kamehameha behind them as they fire.
In Dragon Ball Heroes, it can be used by Goku, Gohan, Beat, and Gogeta.
"An ultimate Ki Wave! Switch off Lock-On to sweep from side to side as you fire."
