The following are some of my favorite sites, and sites which have supplied me with pictures, sounds, whichever.
Planet NamekA great site for pictures, some of which I have gotten from, DBZ comics, sound files, and such. Very good site.
Dragon Ball Z Revolution-The place where some characters originate
Vegetto EX-One of the best multimedia sites I have ever seen. Great for sounds and music from mp3s and MIDIs.
Trunks DBZ and Megaman site-A friend of mine who helped with some music and the outline for the Reploid biography which I updated.
Dragon Ball Domain: Saiyan Knights of the DBZ Realm-A great RPG where there is a different type of roleplaying. More AD&D typed where you have a Gamemaster. Its a really good site.
