Frieza, also known as Lord Frieza, is the main antagonist of the Dragon Ball franchise and the tyrannical self-proclaimed emperor of Universe 7. He is a feared Cosmic Emperor with immense power, capable of transforming through multiple forms, from his initial 530,000 power level to his final form at 12,000,000, and later evolutions like Golden Frieza and Black Gold Frieza after intense training. Frieza is notorious for his genocidal tendencies, betrayals, and pure brutality, yet possesses a charismatic appeal through dark humor. He has been defeated multiple times, including by Goku's Super Saiyan transformation on Namek, but repeatedly resurrects seeking vengeance, participating in tournaments and overpowering even Ultra forms in recent manga iterations.
