Saiya-jin Forms

Super Saiyan
This is a powered up version of a normal Saiya-
jin.When they reach this stage,they're hair turns
bright yellow,a nd they're eyes turn green.The legend
of the Super Saiya-jins state that there can be no
stronger force when a Super Saiya-jin is at battle,but
this definitley does not hold true.Just about all of
the important Saiya-jins reached this stage,this
includes:Goko,Vegeta,Brolli,Gohan,Goten,and
Trunks.The requirements for getting this strong are
simple, you must obtain a power level of over
100,000,and for your first transformation, you must
get super pissed, or else the change will not occur.
Afterwards, each transformation is simple.
Super Saiyan 2
This stage is easily more powerful than normal Super
Saiya-jin form. In this form, your hair gets a little
longer, and your muscles bulge more. Only three of the
Goku, and Vegeta. Gohan reached it during the Cell
Games, and Goku and Vegeta both reached it when they
were fighting each other and Vegeta was charmed into
Majin Vegeta.
Super Saiyan 3
By far the strongest [normal] Super Saiya-jin stage.
This form is one of the most obscure looking, because
your hair is down to your feet, your eyebrow ridges
push out, and your eye brows disappear. However, all
this trades in for an immense source of power, which
definitely helps out in a snap. Only two Saiya-jins
ever reached this,and they were Goku, and the fused
warrior Gotenks.
Super Saiyan 4
This form can only be seen in the Dragonball GT
series.It is not a true Super Saiya-jin [along Z
lines, that is],but something of a mix between Oozaru
and human. In this form,you keep your hair color,you
grow red fur across some of your body[except SSJ4
Gogita, he had brown fur and red hair], and you wear
some weird looking pants. In one of VegettoEX's
editorials,he believes that this form is the true
Super Saiya-jin,because you reach Golden Oozaru from
this form, and a Golden Oozaru was shown in the
background when Vegeta was explaining the Super Saiya-
jin story. I too, must go along with his beliefs,
because it just seems to make more sense.
Oozaru
This form isn't seen much after the early episodes in
Z, but they're shown in GT as well. Oozaru form is
when a Saiya-jin with a tail catches a glimpse of a
full moon, or an energy level that can mimic it. When
they do, they grow fur all over their body,get red
eyes, and grow to immense proportions. When in this
form, their power is 10 times that of their normal
selves.
