Lady Wifi
After Alya mistakenly thought that Chloé was Ladybug, Chloe gets her suspended from school, causing Alya to leave in anger. This exposes her to an akuma and transforms her into "Lady Wifi". Then she returns to the school and uses her powers to video the principal and afterwards, freeze him.

She proceeds to unveil Ladybug's identity. She teleported herself into Chloe's room, froze her, and unmasked her. But then Cat Noir and the true Ladybug appeared, much to her dismay.

When she finally trapped Ladybug in a hotel kitchen, she tried to take off her mask; but because it was magic, the mask didn't come off. Then she locked Cat Noir in the freezer, which knocked the ring off his finger.

The Puppeteer
Alya becomes Lady Wifi against her will after the Puppeteer uses her powers to animate the doll resembling her. Puppeteer then used her to take the other dolls resembling Evillustator and Rogercop which Puppeteer also took control of, and then Evillustrator made her another phone to replace the one Ladybug and Cat Noir broke when they thought the akuma was in her phone again. Ladybug summoned her Lucky Charm after Cat Noir was possessed and tricked Lady Wifi into pausing Puppeteer, and thus, everybody else under her control. After Ladybug released the akuma from Puppeteer's wand and purifies it, she restored everything to normal along with Alya, freeing her from her state.

The Puppeteer 2
Her statue comes to life after Puppeteer takes control of it.
