Fusions

Fusion is a very effective technique in DBZ.
There are 3 types of fusions-----

1. Fusion Dance:It requires that both the fighters must have similar size, build and powerlevel.It is temporary and lasts for only 30 mins. The two fighters have to perform the fusion dance correctly to de-fuse into each other.

• Goku + Vegeta = Gogeta 
• Goku + Vegeta = Fat Gogeta
• Goten + Trunks = Gotenks 

2.Porterra Fusion:In this type of fusion ,the fighters have to wear an earing each in their opposite ears.It is 100 times stronger than fusion dance and it doesn't require similarity between the two fighters.Though it was supposed to last a lifetime, this fusion ended under cetain conditions.

• Goku + Vegeta = Vegeto         

 3.Namekian Fusion:This is the way of fusing in Namekians.1 Namekian fuses into another's body.It does not require any similarity in the 2 Namekians.

• Piccolo + Nail = Piccolo(Just a lot Stronger)
•  Piccolo + Kami = Kamiccolo
