Most cool/awesome/flashy/ultimate ownage attack you know of.

[Broady Brio]

I searched and found nought and out of nowhere came this idea. If there is an older one, please post a link. Much appreciated

So what would be yours? It can come from anything as long as you specify.

Mine would be Gomu Gomu No Storm off One Piece or Gigante Rifle both done by this geezer

I think the whole "Death Star make planet go boom" trick is pretty sweet.

Or in a trying-to-be-funny way, turning off a console or computer. You can make a whole lot of people's lives and worlds go bye-bye in the blink of an eye.

 

[The Maddest March Hare]

Sand Attack and Growl.

That's some scary shit right there.

[Harlemura]

Ubercharge, if that counts as an "attack".
Now is coward killing time!

 

[Time Travelling Toaster]

Kamehameha.
Need I say more?

Spirit Bomb perhaps ^-^ more specifically the one that (I think at least) Kid Gohan does in the before Z series (I forgot the name of it >.>)

 

[Jumping_Over_Fences]

Vash's Angel Arm

NOT BEFORE I PWN YOU WITH CHARM AND DEFENSE CURL BIZNITCH.

But seriously, probably that Rasenshuriken thing from Naruto.
Or maybe Sasuke's Kirin thing from the same series.

I USE HARDEN.

And since I haven't said anything serious yet, the Fatman in Fallout. Mini Nukes, awaaaaaaay.

 

[RavingPenguin]

The Iris summon from Golden Sun 2.
Was it really necessary to summon the giant god of the underworld and blow up half the freakin' planet, just to kill a seagull? Why yes, yes it was, and all because the move looked awesome.

 

[notyouraveragejoe]

Sand Attack and Growl.

Exactly. Don't forget Leer. That always terrified me.

In all seriousness I'd say the Omega Dragon Fist Move Thing by Goku as Super Saiyen 4 from GT since a dragon literally comes out his fist.

 

[Acidoctor]

Ichigo's bankai & hollow forms. Quite flashy. Also, Sanji's MYFOOTISONFIRE (i dont really remember the name) attack.

 

[GRAPPLION]

FALCON PUNCH
