There are two ways to
fuse from two saiyans into one that's really strong.
The first fusion method is called: the
Fusion Dance. Both of the
saiyans have to
perform this dance and do exactly the same as the
other. Another requirement is that
they have the exact same powerlevel,
build and size. Though
not all fusions are
succesful, an example is Fat
Gogeta. They stay as long as 30
minutes fused and after
that they just turn back into their normal selves. The other type of
fusion can only
happen when both of the persons have
an earring in the opposite ear. These
earrings are called: the
Potara Earrings. Also on this
fusion they have
to be the
same size, build and powerlevel. This fusion is said to be permanent
and well sort
of is, but only when nothing abnormal happens. Also the beings from
the Namekians, can use a form of fusion. This is done by
placing the hand on the
other Namekian. No further things or moves are
needed, the mind and power
of the being who the hand was put onto will
go into the other. Though it will only
happen when both of the fighters approve. They can turn back into
anytime they would want to.
