Goku is the most iconic hero in anime history, and though he wins his battle more often than not, his worst moments are indefensible.

Gohan's relationships with Goku and Piccolo are complex and yet simple all at once, but Piccolo was the one who stepped up.

Gohan realizes his hidden potential, surpassing even Goku, during the Cell Saga with his father's belief. Even Lord Beerus, a God of Destruction, shows genuine respect for Goku's achieved strength ...

This is nothing when considering that the character got stronger than Goku in both the Cell and Buu saga, meaning that he has the potential to do so once again with this new transformation.
