Dragon Ball Z, Vol. 14

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.
Our heroes' worst fears have come true: androids #17 and #18,who in time traveler Trunks's future have already destroyed the world, have been activated! And along with them is #16, an android even Trunks doesn't know! With Goku almost dead from a virus, only Super Saiyan Vegeta has a chance against them--unless Piccolo's plan to merge with his ancient enemy Kami-sama will make him the new strongest being on Earth! But something even worse than androids has come back from the future...
