Cell vs. Android 16 is the 371st chapter of the Dragon Ball manga.

Summary

Android 16 approaches Cell, much to the astonishment of Tien Shinhan and Android 18. After Android 17 is beaten and nearly absorbed by him, Cell is punched into the air by 16. Figuring that he and Cell are about equal in power, 16 charges at him, but is knocked to the ground. He then resists Cell's attempt to attack him with his stinger, and pulls his tail out, hoping to prevent 17 from being absorbed. However (due to the presence of Piccolo's cells), his tail grows right back. Android 16 realizes that he must kill Cell so he will not achieve his perfect form, and attempts to kick him, only to be knocked back when Cell counters with two punches. 16 then launches his fist at Cell to retaliate.
