Dragon Ball Z, at its core, is a classic good over evil story. Action, a little romance and some off-the-wall humor make this series one of the top Anime titles watched in the States today. Goku, Gohan and the rest of the Z-fighters protect the Earth from villain after villain with their ever-growing power and strength. This power doesn't come from magic, but rather concentrates the natural energy that surrounds and binds the Universe (who says Anime isn't deep?). And while we all know that the Z-fighters will eventually triumph, it is not without some hardships along the way. As the villains get tougher (and boy, do they ever!), the casualty rate grows. Not to fear, though. Lives can be restored through Shenron, a mystical dragon created by the people of Namek and summoned by collecting the seven dragon balls hidden around the world.
