A power-hungry person is someone who craves and seeks out power and control above all else. They may be ruthless in their pursuit of authority and can be manipulative, domineering, and tyrannical. Other words that can be used to describe a power-hungry person include authoritarian, autocratic, despotic, dictatorial, imperious, overbearing, and tycoon. These individuals often show little regard for the needs or opinions of others and will go to great lengths to achieve their goals. While some may view a power-hungry person as ambitious and driven, their methods and intentions may ultimately lead to more harm than good.
