Evil geniuses and robots go together like ham and
eggs... evil ham and eggs, that is. Henchmen have their place,
but let's face it, they're not cheap to keep. After all, black
turtleneck shirts don't grow on trees. So, the go-ahead villain
realises that world domination depends on cutting payroll and passing
on the increased pain to his victims.
Robot minions are not only cheaper to maintain,
except for their plutonium batteries, but they are also tireless,
remorseless, and unburdened by any concerns for morality.
Granted, they are prone to turn on their masters without a moment's
notice in an orgy of grisly mechanical destruction, but it's all eggs
and omelets, after all.
