Alya Cesaire

Alya Césaire is a student in Miss Bustier's class at Collège Françoise Dupont and Marinette Dupain-Cheng’s friend. She is also the only admin of the Ladyblog and head of the school blog.

In "Lady Wifi", after Alya gets suspended from school because of Chloe Bourgeois, she gets Akumatized by Hawk Moth and becomes Lady Wifi, a supervillain whose powers come from her smartphone and its Wi-Fi signal.

In "Sapotis", after she receives the Fox Miraculous from Ladybug, Alya, when the Miraculous is inhabited by Trixx, becomes Rena Rouge, a fox-themed superhero who helps Ladybug and Cat Noir "during particularly difficult missions" in the second season and beyond.

In "Mayura", during the fight with Scarlet Moth, Rena Rouge is Akumatized into Rena Rage, a fox-themed supervillain.

In "Oblivio", she, alongside Nino, is Akumatized into Oblivio, a memory-erasing supervillain.

In "Félix", after being fooled by Félix to think that Adrien didn't appreciate his friends, she is re-Akumatized into Lady Wifi, and, along with Reflekta and Princess Fragrance, the three supervillains form the The Punishers Trio, a group of supervillains who want to get revenge on Adrien, later Félix.
