Dragon Ball Z, Vol. 23

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.
The mighty djinn Boo has awakened from his aeons-old slumber! As Boo's reign of terror begins, even the mad wizard Bobbidi and his allies question whether such an uncontrollable being should have been set free. With all the universe's greatest champions dead, petrified, or beaten into unconsciousness, only one hero remains to put up a fight...Vegeta. Will he win...or will Boo be free to turn the entire population of the world into sweets and gobble them up?
