8. Maria ('Metropolis')
Basic Function: To pose as a real-life woman named Maria and convince the workers who live in the underworld of the grand city Metropolis to rise up and revolt.
Good or Bad: Her motivations are ultimately to rile the workers up to the point where they revolt, so an evil man from Metropolis can justify a slaughter in the future. When they figure out what's happening and that their children have been put in extreme danger, they burn her at the stake.
Boldest Action: Becoming the first iconic robot in film history.
