God Vs. The Devil
Btw, DBZ is totally flawed. Vegeta was PL of around 20,000 when he destroyed that planet with his two fingers with minimal effort. Then he needed a cannon gun which took all his power to destroy Earth. His cannon gun might have been to kill goku too, but still.
Also, Vegeta was PL around 25,000 when he did his cannon gun. Goku was around 27,000 when he stopped the cannon gun. Now Goku is PL 300,000,000 and fighting buu. That's about 111,111 times stronger then he was when he deflected the cannon gun. Wouldn't the slightest fireball into the Earth destroy the whole thing at this point? Couldn't buu just fart and the entire world would collapse on itself?
I see goku dodging fireballs and crap, but wouldn't those fireballs go into the Earth and then boom?
I don't even wanna think about DB GT.
But then.. it's just a cartoon.. err anime.
