Nr. 18  She is another creation of Dr. Gero with the  destiny to destroy Son Goku. Kuririn fell for her after his first  encounter with her. She was unable to escape the persistance  of 2nd stage Cell to become 3rd stage ("Complete Form"), and was  finally engulfed by him to achieve his dream of the "perfect  fighting machine." We don't see #18 again until after Cell  was nearly destroyed by Son Gohan and spits her back out. Kuririn  "rescues" her and they subsequently settled down with a daughter.
