@Luffyshirou:
There is one difference between DBZ and one piece. In one piece things are more realistic. However in DBZ where the heck does all the BEAM energy come from!!?? You can easily destroy planets??? That's what i don't like about DBZ. Other than that it's a good fighting anime.
Uh… you've only seen Dragon Ball Z and you've only seen it in English am I right?
Please correct me if I'm wrong…
It's all explained in the Japanese version, and it's not "BEAM" energy, it's manipulation of Ki(or Chi as Viz translates it) which is the "Life Essence" so to speak. Yu Yu Hakusho has something similar known as "Spirit Energy".
And how is a show about pirates with special powers from eating fruits, fighting chefs, and transforming reindeer with a main character who can stretch his limbs in ways that would make Dhalsim ashamed more "realistic" than Dragon Ball?
