After being expelled from school, Alya is akumatized into Lady Wifi, a villain who will stop at nothing to expose Ladybug.

Lady Wifi has a black butterfly-shaped mask on her face, and her eyes are dark magenta. She wears a black suit, her lower arms, and legs white with three stripes that are white above each. On her chest is a glowing hot pink Wi-Fi symbol, and a thin white line goes around her waist, with the line creating a semicircle above a short vertical white line in the front, resembling a power button.
