Dragon Ball Z, Volume 14 — Akira Toriyama

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...
