Yes, only Goku and Gotenks (Goten + Trunks) achieved it. There is also a SS4 which Goku and Vegeta achieved. There is a fan illustration of Goku SS5 but there is no story to go with it.
there is not a super saiyan 2 gotenks. He can only transform into a super saiyan and a super saiyan 3.
A super saiyan god is the saiyan among super saiyans its in between super saiyan 3 and super saiyan 4 super saiyan god has red hair and red eyes.
5.... super saiyan 1 super saiyan 2 super saiyan 3 super saiyan 4 Oozaru or great ape there's also a super Oozaru
Super Saiyan Super Saiyan 3 Super Saiyan 4 Super Saiyan 5 (platinum elite) Majin Saiyan Legendary Super Saiyan (only for Broly, of course)
Super Saiyan, Ultra Super Saiyan, Ultimate Super Saiyan, Full Power Super Saiyan, Super Saiyan 2, Mastered Super Saiyan 2, Super Saiyan 3 and 100% Super Saiyan 3. In GT, Super Saiyan 4 exists. Some belive that SSJ4 Goku fused with Shenron and absorbing the dragon balls is the equivilant of "SSJ5" which only exists in DB AE/AF which are fanmade creations.
Episode 230 "Super Saiyan 3"
movie 8 the legendary super saiyan
Here they are:Goku: Super Saiyan 1, 2, 3, and 4Vegeta: Super Saiyan 1, Ultra Super Saiyan(Ussj), Super Saiyan 2, and 4.Trunks: Super Saiyan 1, Ultra Super Saiyan(Ussj), and Super Saiyan 2.Gohan: Super Saiyan 1, and 2.(Though he has Ultimate Gohan form, it doesn't really count.Teen Gohan: Super Saiyan 1, and 2.Kid Gohan: He doesn't turn Super Saiyan yet.Goten: Super Saiyan 1.Broly: Legendary Super Saiyan.(The rest like 1, 2, or 3 are not shown in DBZ)Gogeta: Super Saiyan 1, and 4.Vegito: Super Vegito(Which I think counts.)
It is Super Saiyan 3. But in Dbgt it is Super Saiyan 4
Goku does not turn super saiyan 6 or 5 in fact. and it only goes up to super saiyan 3 in the manga and super saiyan 4 in the cartoon.
if gotenks made him made super saiyan 3 wouldn't matter because gohan would be as strong as gotenks super saiyan 3 plus teen gohan rulez
