Registered records for Babidi before world filtering: death 1, killing 2. Counts describe entries, not people or lifetime totals. Death sources include Chapter 475.
The filter uses the world where the event occurred, not the character’s origin. Distinct future branches remain separate entries.
Buu knocks Babidi's head off and then erases his body with an energy blast. Babidi was still alive after Piccolo severed his body and dies in this attack.
