Ok, time fo mah ssj guide for noobs baby!
Sayajin: Normal black haired black eyed sayain.
Super Sayajin: Super Sayians are about a 1/3 more powerful stat wise than normal sayains, and have twice the power level. The hair turns gold-yellow and eyes turn blue
Assended Super Sayajin(Ssj2 for short) Is an sayain who is 2/3's more powerful than a sayian stat wise, and the power level is doubled yet again! hair is still gold-yellow, but shines more. eyes turn green, ssj2 sayians are known for being fast.
Ultra Super Sayains: Are a trade off, you can go ether Ssj2 or ussj, ssj2 is same stats as above, but ussj's lose a 1/3 speed but grow a 1/3 stronger, as in body mass, simply put, stronger, but slower than ssj2. Hair gets thick and flys everywere, eyes go blank(Pulse,whiteout, what ever you call it) once again ussj's get very strong.
Super Sayajin at peak(Or Ssj3) super sayajin's who reach there peak are like this, only goku and gotinks can do this(Vegeta and trunks can go ussj)
An ssj3 has double the pysical stats of a normal sayian and his power level is yet again doubled! hair grows very long and eyes turn blue again...
Legendary Super Sayian: Is just like an ussj only with two major diffrences...
one is, only Broily can do it
Two is, like an ussj Broily bulks up and gets extra strong, but also... Broily keeps his speed, so its like an ussj and ssj2 in one. both strong and fast, Lssj is really the same as going ssj3 only better because your hair does not get in your way as much...
Ssj4: is something that is made up for dbgt, althoguh many people denie it because its not "really" dbz... Ssj4 is still there, and the maker of Dbz akiry torinama(Sorry i know i did not spell that right...but i can never remember how to...) he did think about it. in the mean time, ssj4's hair and eyes turn back to black, and they grow and red "Fur" like hair over there bodys. tail also grows back even if you have cut it off at the roots or are over 18(Sayains can not grow back there tails if tail is removed after a sayains prime)
Any questions?
