Registered records for Android 19 before world filtering: death 1, killing 1. Counts describe entries, not people or lifetime totals. Death sources include Chapter 344.
The filter uses the world where the event occurred, not the character’s origin. Distinct future branches remain separate entries.
After Android 19 loses both arms and attempts to flee, Vegeta destroys him with the Big Bang Attack, leaving the remains of his head. This is recorded as the destruction of a fully mechanical android.
Android 19 strikes down two men on the street. Yamcha later finds their bodies, and Android 20 acknowledges that the androids killed them. They are separate from the driver attacked by Android 20.
