Fusion Guide

--- Fusion is pretty much this : in the Dragonball Z world, two people can become one being, which greatly enhances their power.  Early on we see fusions from the Nameks, Nail and Piccolo.  Later we see Piccolo once again fuse with Kami.  These fusions are not to me confused with the Saiya - Jins.  The Namek's fusion is permenant, while severe concentration can possibly split the two apart (ex. Piccolo and Kami).  The Saiya - Jin fusion goes something like this : either the Saiya - Jins found the fusion earrings, or they can use the fusion dance.  Either of which will allow the two to become one.  The earrings last forever, while the fusion dance lasts for 30 minutes.  The fusion pairs go as follows:

Vegeta and Goku : Gogeta and Vegetto

Goten and Chibi Trunks : Gotenks
