if you could learn one fictional martial art attack

[Wintermoot]

any from ANY movie/anime/comic/toon/manga yes G Gundam attacks count
I would choose Shining Finger Sword from G Gundam or the ATATATATATATA attack from Hokuto No Ken
PS: attacks that require a weapon also count and Gun-Fu

 

[Axolotl]

Five Point Palm Exploding Heart Technique.

Not the most efficient but the coolest.

 

[Blackmagic1515]

Neji Hyuuga's 64 palm attack. I'd love to have that speed and be able to quickly disable my opponent.

 

[Palademon]

Hadouken.
Even better if it be made of cookies.

 

[Casual Shinji]

Just the usual "rapid fist attack" would be enough for me.

 

[Queen Michael]

Whatever it is Deadpool uses to be so gosh-darn hardcore.

 

[hwarang]

Wolverine's "3 claws protruding from my fist as I uppercut that beefy dude's jaw" punch.
Yes.

 

[The Amazing Tea Alligator]

Five Point Palm Exploding Heart Technique.

Not the most efficient but the coolest.

Spoiler: Very much so. Oh and this is a spoiler for Kill Bill pt2

It begins at 3:00-ish.

 

[Vinylsiding]

The Buddhas Palm from Kung Fu Hustle.

 

[Antitonic]

After very little thought, I've decided I'd have this one [http://www.egscomics.com/?date=2002-04-16].

Useful in battle situations.

 

[Alexander Cron]

Dim Mak, The Touch of Death, would be just awesome. Being able to kill someone that easily would be pretty cool.

 

[Kraj]

Way of Stone:
/immortality. "Its a defense that makes you invulnerable, so its a perfect offense too"

 

[Jezzascmezza]

Five Point Palm Exploding Heart Technique.

Not the most efficient but the coolest.

My thoughts exactly.
Uma Thurman makes it look so bad-ass too.

 

[Beartrucci]

The Ultimate Punch.

 

[ironduke88]

KAME...HAMEE.HAAAAAAAAAAAAAAAAAA

 

[Cogwheel]

Something defensive.

While it's not martial arts as such (more of a dashing broom-uppercut-leap thing), I'm tempted to mention a move from a certain game called Hisoutensoku, which I assume no one's ever heard of. Why? It has the best leaping uppercut move name ever: Escape Velocity.

 

[Hothcliff]

Spoiler: the Wuxi Fingerhold

"Ah, You know this hold?"

 

[ANImaniac89]

The Buddhas Palm from Kung Fu Hustle.

YES

 

[Not-here-anymore]

Hadouken.
Even better if it be made of cookies.

Curse you, ninja!

Hadouken being taken already (and me not knowing any other street fighter moves other than shoryuken), I'll take Kazuya's lightning screw uppercut. Or Paul's phoenix fist. Anything with fire or lightning involved, really.
