Buu Saga Goku
Goku can only go SSJ
Takes place where Gohan fought Dabura
@UltimateHero0406: In this case it does however because he saw how Dabura fought against Gohan and he could sense Dabura's energy and make a comparison based on that, when he faced 18, he could sense no energy and could therefore not gauge how strong she was, also along with the fact that he still believed that super saiyans were invincible.
@SpeedForceSpider: Yes he did go SSJ2 as you can see: on the left is when he trained Goten and turned SSJ, on the right is when he fought Dabura and is clearly SSJ2. Go look up on some SSJ>SSJ2 pictures of Gohan/Vegeta/Goku and you would see the difference between an SSJ and SSJ2. Thats why i never understand Broly fans who constantly say that Goku was SSJ2 in the second movie witch he clearly wasn't.
You and i already discussed heavily why i think Dabura is an SSJ2 lvl and why you think Dabura is only at Perfect Cell lvl so there is no need for us to go 3+ pages again and repeat ourselfs.
