In my opinion, In the Wrath of the Dragon DBZ movie when Goku does the Dragon Fist to kill the monster is the best attack evar. A close second is Stardust Breaker that Gogeta performs on Janeraba
My favorite attacks in anime would have to be:Grand Rey Cero(Bleach),Cero Matrelleta(Bleach),Infinite Sword Flow(Soul Eater),Death's Shinigami Shop(Soul Eater),Final Flash(DBZ),Kirin(Naruto:Shippuden),Zoro's Asure Attack(One Piece),Zekkai(Kekkaishi) and Rasenshuriken(Naruto:Shippuden)
yusuke's rei-gun is good from Yu Yu hakusho
Vash's "Plant mode" or whatever is called is really bad ass, from trigun
Kuro's "time warping/matrix type attack" from Kurozoka is cool too
Ichigo/hollow ichigo, when they spin and through Zangetsu by the hilt wrap, all though they don't do that much anymore, Bleach
going back olRABchool is Ranma's version of the "Lions roar", and ryoga's breaking point from ranma 1/2
I like eruka's attack with the tad poles in soul eater it's wimpy but it's way cooler than anything else here lol =3
but for best attack, I really like ichigo's getsuga tenshou while he's using his bankai
and my favorite attack is in one in fma, in the movie, where alphonse was able to posses metal suites and fight that way. that was pretty amazing
That was SO EPIC! I was ging to say the Kamehameha by Goku or Burning Attack by Trunks, but that one takes the cake! I got nothing to rival the awesomeness of that attack.
Dang straight, this attack was unbelievably awesome.....I know for plot issues it couldn't happen, but what if he used this on Yuske in the beginning? That would've sucked...
