"Big Bang Kamehameha"

Cool name, but it was trash in the anime. I'm a fan of the Big Bang Attack, Final Flash and the Galick Gun.

Alright then, Galick Kamehameha and Final Kamehameha will do the job. De-Fusion's already served it's purpose which was to defuse one Fusion character. But assuming it's Gogeta and we've seen Goku and Vegeta use Galick Kamehameha we can have that happen and Vegito Blue using Final Kamehameha. You can see it both ways,

What's stopping them from still destraoying it after being de-fused? It doesn't just make Goku and Vegeta useless

defusion's main purpose was to defuse them and it worked so yeah they're free to destroy it. It's a victory on both sides.

Half Victory for the card user cause great you can defuse one of the universe busting fusions. Great, but no matter which one you decide to defuse as the card can only work on one fusion per turn, meaning you’ll either have a Gogeta learn what that card does and blitz ya destroy it and kill ya, or defuse Gogeta and get Vegito doing that. Plus both in either scenario would be getting on needed help from Goku and Vegeta.

You make a good point, wrong post sorry.

Wrong post buddy. This is the defusion card.

Oh sorry, my mistake. I thought this was the recent one. thanks man.

Well it depends if the defusion card can so much as to defuse fusions from different animes. It wouldn't matter anyways, they would still win
