Saiya-jin: Saiya-jin is the origonal level and the Saiya-jin still has his black hair.
Super Saiya-jin: Super Saiya-jin is the first level of the Super Saiya-jin process. The Saiya-jin's hair turns blond, his eyes turn green and his power increases dramatically!
Super Saiya-jin 2: Super Saiya-jin level 2 is the same as Super Saiya-jin level
1 except the Saiya-jin's hair is longer and is stronger.
Super Saiya-jin 3: Super Saiya-jin level 3 is another cycle of the process. The Saiya-jin's hair goes all the way down to his knees and he is much stronger
Super Saiya-jin 4: Can only be reached in from the Golden Ozoura stage. Although
this is not a true Super Saiya-jin level it is the strongest form of them all. The Saiya-jin grows red fur on his chest, his eyes turn yellow, and his hair turns back to its origonal color. He also grows his tail back.
Ozoura: If the Saiya-jin has a tail he will turn Ozoura when a full moon comes out (or turn into a huge ape).
Golden Ozoura: Basically the Saiya-jin turns Super Saiya-jin and then transforms
into the Ozoura stage.
