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.

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!
