Dragon Ball Z: Supersonic Warriors/Gohan

Gohan is the second main character of Supersonic Warriors and son of Goku. His story starts off with the death of Goku at the hands of Dr. Gero. Goku dies for good this time, since he can't be revived again. Gohan, angered by the death of his father, musters up the power for Super Saiyan transformation, and his first battle begins. Gohan mostly has the role of taking the place of main hero from his father throughout the story, and you also get to fight as him when he's fully-grown.
