Dragon Ball, Vol. 18

The countdown to extinction begins! Goku has paid the ultimate price to stop Raditz, but the danger is far from over. Before his death, the alien conqueror warns that two even more ruthless, incredibly powerful Saiyan warriors are heading to Earth, and they will arrive in exactly one year. With Goku training in the afterlife on King Kai's planet, Earth's defense falls into the hands of his closest allies. Piccolo takes a terrified young Gohan into the wilderness for a brutal, unforgiving survival crash course to unlock the boy's hidden, explosive potential. Meanwhile, Krillin, Yamcha, Tien, and Chiaotzu push their bodies past their limits at the Lookout. As the months tick away, the Z-Fighters must prepare for an apocalyptic clash. If Goku can't sprint across the million-mile Snake Way and return to life in time, the Saiyan invaders will reduce the entire planet to ash!
