Dragon Ball Z, Vol. 17 (Dragon Ball Z)

Sci-Fi martial arts action! After years of training and adventure, Goku has become Earth's ultimate warrior. And his son, Gohan, shows even greater promise. But the stakes are increasing as even deadlier enemies threaten the planet. DRAGON BALL Z is the ultimate science fiction-martial arts manga. Now in his Perfect Form, Cell is stronger than any creature alive--even the muscled-out new form of the mighty Saiyans. Finding no competition on Earth, Cell invades a TV studio and gives the world an ultimatum: produce a fighter who can beat him in one-on-one combat, or he will methodically slaughter every living thing! But does the human race…or even the Saiyan race…have a champion who can go up against Cell? Plus the alternate-timeline story of Trunks' origin!
