megalomania

Megalomania is a crazy hunger for power and wealth, and a passion for grand schemes. Comic book villains often suffer from megalomania. Their plans are thwarted only by superheroes.

Megalomania comes from the Greek megas ("great") and mania ("madness"). It is a madness of greatness, but not a great kind of madness! Megalomaniacs in history include Alexander the Great, Genghis Khan, and Napoleon Bonaparte. People with megalomania tend to exaggerate their virtues and never see their faults.
