Rena Rouge

Alya Césaire, a.k.a. Rena Rouge, (voiced by Carrie Keranen) is a student in Miss Bustier's class at Collège Françoise Dupont and Marinette Dupain-Cheng's best friend. She is also the sole admin of the Ladyblog and head of the school blog.

In the Miraculous: Tales of Ladybug & Cat Noir episode, "Lady Wifi", after Alya gets suspended from school because of Chloé 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 Alya receives the Fox Miraculous from Ladybug, when the Miraculous is inhabited by Trixx, she becomes Rena Rouge, a fox-themed superhero who helps Ladybug and Cat Noir "during particularly difficult missions" in the second season.

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

In "Oblivio", Alya, alongside Nino Lahiffe, is akumatized into Oblivio, a memory-erasing supervillain.
