The designation “Android 16” is simply that a label assigned to a powerful artificial human created by Dr. Gero. The character doesn’t possess a conventionally assigned personal identifier like a birth name. Instead, its existence is defined by its purpose and its creator’s intentions within the Dragon Ball universe.
Understanding that this artificial being lacks a proper name is important because it highlights Dr. Gero’s detached and scientific approach to his creations. The numbering system reflects their place in his overall plan for revenge. This designation allows focus on its function, abilities, and eventual contribution to the narrative arc, rather than personal history or identity.
