Dragon Ball Vol. 12 — Manga Raw / Buy Official

Raditz tries to pull his brother Goku into the Saiyan warrior caste and takes young Gohan hostage when Goku resists. Unable even to sense ki, Goku and Piccolo fight together and are beaten down by Raditz's overwhelming power. Then Gohan, furious at his father's peril, unleashes a flash of hidden strength that stuns Raditz. In that gap Piccolo's Special Beam Cannon pierces Raditz and Goku, who makes himself the shield. Dying, Goku entrusts Gohan's training to Piccolo; Piccolo, eyeing that latent power, takes the child into the mountains for brutal training. Goku's spirit starts down Snake Way toward King Kai of the North. Earth's peace is over, and training begins for the two Saiyans due in a year.
