It just occurred to me that Trunks was nowhere near as powerful as Gohan was.
He never reached SSJ2
He never had the Mystic Form
He never had those explosive bouts of power
He never had the potential Gohan seemed to have
I mean, he did reach SSJ easier compared to the others but it seemed that was the peak of his potential.
I thought the entire thing was that half-SSJ breeds are inherently very powerful.
