Hidden power

As a child, Gohan is known to have within him a seemingly limitless dormant power, which at first only revealed itself when he experienced fierce rage, which is likely the reason that Goku never noticed it. As he got older, he trained hard and gained access to a large portion of his power, and it was not until he was a young adult that his power was fully awakened and he was able to use it all at his own will. He displays exceptional power at a very young age, even surpassing his father Goku and saving the world from the evil Cell at only ten years old (eleven counting time in the Hyperbolic Time Chamber). Gohan's latent power is finally released to its fullest extent in the Fusion Saga, making him the one of strongest characters in the series, and the strongest character in the manga to be unaided by fusion or absorption. It should be noticed that from all the Z fighters Gohan has surpassed Goku the most times.
