Dragon Ball Z Vol. 16

THE ROOM OF SPIRIT AND TIME

Cell has fused with android #17, becoming practically invincible-but not for long! Training in the Room of Spirit and Time, where a year passes for every day outside, Vegeta and Trunks have gone beyond the Super Saiyan, reaching a level of power even greater than second-stage Cell! Now Cell is the one who is outmatched-but Vegeta hates a boring fight. Succumbing to his pride, Vegeta agrees to help Cell fuse with android #18, the last element he needs to become "perfect", so he can have the honor of defeating the strongest being in the world!
