If Goku can't do it, who will?

Before the announcement of the new Dragon Ball Z movie "Battle of Gods", which will premiere in March 2013, the last movie of the DBZ era was "Wrath of the Dragon" as it's known in English. In Japanese, it was something like, "Dragon Fist Explosion!! If Goku Can't Do It, Who Will!?" So, yeah, I personally prefer the Japanese one, it's much more dramatic haha
Anyways, both titles refer to a technique Goku uses at the very end of the film against Hildegarn, the giant beast who's the enemy on this film. He also uses on Dragon Ball GT, now that I think about it...
The Super Dragon Fist, which manages to completely defeat the monster in just one blow, is easily Goku's most powerful attack, but there's a catch. Toriyama didn't create that technique for Goku, so lots of people don't consider the Dragon Fist attack to be canon. Still, it's pretty damn awesome to look at XD
Dragon Ball and everything related to it are owned by Akira Toriyama, Shueisha, and Toei.
