That was Cell saga, Gohans the first to get that form which he does against Cell. You get variations on the first Super Saiyan form which is Super Saiyan Second Grade and Third Grade, which are achieved by Vegeta and Trunks, but its still considered just Super Saiyan. Goku and Gohan achieve Super Saiyan Full Power, which is mastery over the base Super Saiyan form.
