I started watching Dragonball Z again, and came across the episode where the Elder Kai releases Gohan's inner strength, he then tells him that he cannot transform into a super Saiyan anymore, and he really doesn't need to, because his mystic powers are much stronger then a super Saiyan. So why in dragonball GT he turned ssj? Wouldn't he want to fight in his strongest mode? Was it because he didn't train for a long time and lost his mystic powers? Or its just because GT is a crappy season?
