Just name it and then we´ll see which one is the most voted.

[Walbuls]

Goku's Spirit Bomb or kamahamaha

I dunno...

Hiei's Dragon of the Darkness Flame (From YYH)?

[Akonyl]

I'd guess something that TTGL does

like...
[spoiler]when TTGL shot so many missiles that it hit every point in the universe, at every point in the past, and future. You can't get much better than attacking the entire space-time continuum at once. Although apparently you can because that still didn't kill the anti-spiral.[/spoiler]
