He is Dr. Gero's 16th Android creation, whose template was Gevo. Despite his intimidating size, monotone dialogue, and seemingly dangerous appearance, Android 16 is calm, friendly, and embraces nature and humanity, aside from a cold and distant attitude towards Goku in particular, since he was initially programmed to eliminate him. He does not tolerate evil and described Perfect Cell as an existence whose purpose is to destroy life, especially nature and animals.
