Affectionate Android is the second level of the What If saga in Dragon Ball Z: Budokai Tenkaichi 3.
Doctor Gero sends Artificial Human No. 16 into the past so he can fight a younger, weaker Son Goku. Artificial Human No. 8 tries to protect Goku and Goku tries to help No. 8. Goku is then hurt. Eighter goes into an angry rage and damaged No. 16, thus making him unable to fight.
No. 16 can be defeated by Goku or No. 8. If No. 8 defeats him before pressing the transformation button after switching from Goku to No. 8, the dialogue will be different and No. 16 will be killed.
