FUSION!

NAMEK FUSION-This is the fusion that can be performed by Nameks, first they determine which body they use then they have one of the Nameks put their hand upon the chest of the other and the Namek who knows how to fuse triggers the fusion just like that and then the person whos body was not chosen to be kept just disapears. This process as told by Nail can be undone however, the fusion between Piccolo and Kami cannot because they were originally one being in the first place.

FUSION DANCE-This fusion is done by a dance that two people of any race can perform, however they must be relatively equal in size and power, which is not much of a problem for the Z warriors as they can raise and lower their power level, unlike the Namek fusion the two people fuse into a completely different being who looks like a cross between the two who perform the fusion, this fusion ends after 30 minutes until the two people unfuse, another fact is that when people fuse this way they always get the white pants and black and orange vest as clothes.

POTARA EAR RINGS-This fusion is very similar to the fusion dance except that instead of a dance one person puts an ear ring on their left ear and the other person puts an ear ring on their right ear and then they are fused together, permanantly. The only reason that Vegeto unfused back to Goku and Vegeta is because when Vegeto was aten by Buu Buu's stomach had to break them down as all stomachs do to food, so Goku and Vegeta were broken down back to themselves.

Piccolo and Nail-This is the fusion of Piccolo and Nail during the Freeza saga, the fusion took place right before Piccolo fought with Freeza and apparently Piccolo felt wonderfully stronger after the fusion.

Piccolo and Kami-This is the fusion of Piccolo and Kami where they fused back into their original self...Piccolo. Because they had to use Piccolo's body Kami disapeared and thus the DragonBalls disapeared and so this is why they had to get Dende to be Earths new guardian.

Piccolo and...Krillin?-This fusion character is refered to as Kuricolo, but I don't know if this fusion actualy took place or if Akira Toriyama just drew it for a magazine or something, but this picture IS here so I guess he drew it at sometime.

Gotenks-This is the fusion of Goten and Trunks by way of Fusion dance, they use this fusion more often than most of the other Z warriors and have some pretty dumb moves to go along with it due to the cockiness that comes with the fusion dance characters. This happens to be the only fusion character to reach Super Saiyan lavel 3.

Gogeta-This is the fusion of Goku and Vegeta by way of fusion dance and is the only fused character to reach Super Saiyan level 4.

Vegeto-This is the fusion of Goku and Vegeta by way of Potara ear rings...Not much more to know.
