Dragon Ball Z : Vol. 10
(Young Adult Book)

As Freeza changes into new forms, each more powerful than the last, the desperate heroes--Gohan, Kuririn, Piccolo and the self-serving Vegeta--find themselves struggling merely to stay alive. Desperate for a trump card, Vegeta asks Kuririn to mortally wound him, so that his auto-evolving mechanism will turn him into the legendary strongest fighter in the universe--the Super Saiyan! On the other side of the planet, Goku awakens from within his healing capsule and streaks to the battlefield to turn the tide. But even in his final, supposedly deadliest form, Freeza has an ace up his sleeve...
