MODIFIED HUMAN OF EARTH ANCESTOR POWER ++

Androids 17 (Lapis) and 18 (Lazuli) are canonically pure human teenagers who were forcefully kidnapped, surgically altered, and heavily cybernetically modified by Dr. Gero.

• Biological Origin: Before Dr. Gero's experimentation, both 17 and 18 were ordinary human beings with organic bodies, distinct human names, and families.
• The Nature of Modifications: Dr. Gero did not build them from scratch as fully mechanical robots (unlike Android 16). Instead, he used living human teenagers as his base subjects, upgrading their skeletal, muscular, and circulatory systems with advanced bio-mechanical cybernetics, artificial energy sources, and infinite power reactors.
• Manga Evidence: In the Dragon Ball Z manga (specifically during the Androids and Cell sagas), characters frequently reference their human past. Most notably, Krillin discovers their human origins and birth names via blueprints found in Dr. Gero's secret laboratory, and uses this realization to connect with Android 18 on a personal level. Furthermore, because their foundations remain biologically human, Android 18 is organically capable of conceiving and giving birth to a child (Marron) with Krillin.
• Terminology Translation Nuance: The original Japanese manga refers to them as Jinzōningen (literally meaning "artificial human" or "man-made human"), a broad term in Japanese science fiction that covers cyborgs, androids, and biological constructs. While English localizations translated this as "Android," characters like 17 and 18 are scientifically cyborgs—humans fused with mechanical technology.
