- Here is a list of the techniques used, characters involved and what fusion they produce

DBZ Fusions

Fusion by Name

This fusion is done by placing the hand on the nameks chest and then is then is absorbed into the nameks chest and then they are fused

Piccolo + Nail = Piccolo (Piccolo is the base and it looks exactly like him)
Piccolo + Kami = Kamiccolo (Actually it makes Piccolo but this is what Goku called him when he first saw the fusion)

Fusion Dance

This is done by doin a kool dance, they turn out different to there normal selves, this only last for 30 min

Goten + Trunks = Gotenks
Goku + Vegeta = Gogeta
Goku + Vegeta = fat Gogeta (This happened because of a mistake in the dance)

Potara Earrings

When the two warriors wear the Potara Earrings on opposite ears, then they hold hands, and then they immediately get pulled together in a fusion. This fusions result is different from the others because their voice, clothes, and looks combine, and they canot unfuse. Characters that fuse:

Vegeta + Goku = Vegetto (They manage to unfuse when they were absorbed by Buu)
