Gohan

Son Gohan ( 'Son Gohan') is a half-breed Saiyan and one of the most prominent characters in the Dragon Ball series. He is the elder son of the series' primary protagonist Goku and his wife Chi-Chi, the older brother of Goten, the husband of Videl and father to Pan. He is named after Goku's adoptive grandfather, Gohan.

Unlike his father, Gohan lacks a passion for fighting (although, he does possess a strong power within him) and prefers to do so only when his loved ones are threatened.[6]  Nevertheless, Gohan fights alongside the Dragon Team in the defense of Earth for much of his life. Gohan also known as the Savior and the Greatest Light

Twice Blessed Child
The Prophecy of the Twice-Blessed Child is an ancient prophecy describing the birth of a child holding great Ultimate power (hidden power which what gohan has been calling it) .When three planets burn as one over a sky of dancing light, and power levels will become drain or wery for a day to welcome a twice blessed child. If nurtured properly, the child would become a savior of the world; but if he falls under the influence of evil, he will become the world's ultimate destroyer.

"When three planets burn as one
 * over a sky of dancing light,
 * Magic will rest on a holy day
 * to welcome a twice blessed child."
