I can't tell you the episode but it was in the early parts of the Buu saga.
he doesn't learn it.so never.he first goes super saiyan in episode 95.
goku, goten never goes super sayian 4
Goku can go Super Sayian Stage 1, Then Ascended Super Sayian or Above Super Sayian Stage 2 but below Super Sayian 2 Stage 3, Stage 4 is Super Sayian 3, Stage 5 is Super Sayian 4!
yes if he can turn super sayian and super sayian 3 cause when goku turn great ape he also turn into a super sayian at the same time but if goku jr wants to become super sayian 4 then he has to remember something to calm him down when he is in great ape form
no
Ss4 Goku is more powerful the Gohan. Always because Goku is 100% Sayian and Gohan is 50% Sayian!! ;3
goku turnes super saiyan in dbzkai is episode 47 and ends freeza in episode 48
goku super sayayin 3
Yes Goku is stronger than Pikkon as you remember they were only true equals during the end of the cell games saga . Were Pikkon was only able to go toe to toe with Goku in his super sayian form . Both were equal but overall goku seemed to be the greater fighter even after their fight . Now at the end of the Kid Buu saga goku managed to reveal that he surpassed gohan at super sayian 2 when he revealed his super sayian 2 tranformation , and should have definitly proved it when he turned into super sayian 3 . So if Goku could beat Pikkon in his normal Super sayian transformation what gives you a chance he can beat him in super sayian 3 . I would just overkilled the answer and said that Goku SS4 in GT . But sadly its not official it is all OVA . But Goku by the end of the kid buu saga he reaches super sayian 3 which clearly is multiple times stronger than his super sayian transformation .
He doesnt have an item when he turned super sayian it was his anger so he turns super sayian by combinding his energy.
Super Sayian Goku
Depends on which game you are talking about?
