Term Life Insurance -- yes, this infographic was sponsored by the insurance industry -- put together a chart illustrating the relative difficulty, powers, and motivations of ten prominent evil bosses from video games. Pictured above is one selection of the larger infographic, which is available at the link.
I've noticed that a lot of pop culture infographics these days are sponsored by companies that you'd never think would have an interest in the subject. Perhaps it's successful advertising.
