Dragon Ball Z, Vol. 13

Warned by the time traveler Trunks, Goku, Kuririn, Tenshinhan, and Piccolo go forth to combat the evil androids. Goku challenges them to battle, but the androids can absorb energy from their opponents, becoming stronger and stronger as the fight progresses. Will the arrival of Vegeta turn the tide? Or will Earth's heroes be defeated a second time by foes who, in Trunks' future, have already destroyed them?
