As you all know, there are distinct Sagas in DBZ... Saiyan/Vegeta Saga, Frieza Saga, Cell, Buu... And all kinds of further subdivisions like the Androids Saga and the Heaven's Tournament Saga...
It's pretty well defined... DB is almost the same... There are distinct Sagas, each with their own main sub plot...
Those plots can be things like a main bad guy... Like the first Saga, the Pilaf Saga, or Piccolo Diamaoh Saga... Or an event, like the Tenka'ichi Budokai Sagas...
And each Saga introduces it's own new characters... And the existing characters change from Saga to Saga...
This section will give summaries of each Saga, and contain bios of all the major players in each of those Sagas, and there will be pictures of what those characters look like during that particular time...
Also, our heroes travel all over their world, and visit numerous locations... some of these locations contain Dragon Balls, some of them are major settings for the plot... All of the important locations for each Saga will also be given, along with any Dbs found there, and a brief description of why they are important places...
So...enjoy!
