Power is the Blood Fiend in Chainsaw Man, a loud, arrogant, and chaotic individual who behaves more like a wild beast than a human. She is bloodthirsty, selfish, and shamelessly lies to avoid responsibility. She takes great pride in her strength, often boasting about her superiority and declaring herself the strongest. She also has a strong aversion to hygiene and vegetables, further emphasizing her crude and untamed nature.
