Created for one sole purpose, #17's mission is to destroy Goku. Constructed from a human base, #17 is not completely mechanical. Initially under the control of Dr. Gero, he breaks free and kills him. Even with his creator destroyed, #17's internal programming still gives him the urge to search for Goku and destroy him.
