Which kind of crazy-ass parent installs a freaking EM cannon on a body double???
Dr. Tenma (and everyone in his mold that creates a "replacement goldfish" robot). (Actually, so far as 'robot replacement of a dead family member' goes, it's more common than not for the robot replacement to be more armored than a tank and more heavily armed to boot...)
Forcing their "lady" to get her hands dirty, really?
Oh, for goodness' sake, what a disgraceful state of affairs this is.
