Alya Cesaire

**Alya Césaire** is one of the four deuteragonists (alongside Tikki, Plagg and Nino Lahiffe) of Miraculous: Tales of Ladybug & Cat Noir. She is a former student in Miss Bustier's class at Collège Françoise Dupont, Marinette Dupain-Cheng's best friend, and Nino Lahiffe's girlfriend. She is also the only admin of the Ladyblog and head of the school blog.

In "Lady Wifi", after Alya got suspended from school because of Chloe Bourgeois, she got akumatized by Hawk Moth and became Lady Wifi, a supervillain whose powers came from her smartphone and its Wi-Fi signal.
In "Sapotis", after her younger twin sisters are akumatized into the titular villain, Alya receives the Fox Miraculous from Ladybug. When the Miraculous is inhabited by Trixx, Alya becomes **Rena Rouge**, a red 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, while trying to protect Carapace from one of Dark Cupid's arrows, Rena Rouge was akumatized into Rena Rage, a red fox-themed supervillain.
In "Oblivio" due to her and Nino's embarrassment at being caught playing the Super Penguino video game together, she, alongside Nino, were both akumatized into Oblivio, a memory-erasing supervillain.
In "Félix", after being fooled by Félix to think that Adrien didn't appreciate his friends, she was re-Akumatized into Lady Wifi, and, alongside Reflekta and Princess Fragrance, the three supervillains formed the Punishers Trio, a group of supervillains who wanted to get revenge on Adrien, later Félix.
In "Gang of Secrets", after Marinette kept hiding secrets from her and the group, Alya was reakumatized by Shadow Moth into Lady Wifi alongside Reflekta, Princess Fragrance, Timebreaker, and Horrificator. The five supervillains all formed the Gang of Secrets, a group of supervillains who wanted to reveal Marinette's secrets. After they were defeated, due to all the pressure she had been under since becoming the guardian, Marinette decided to tell Alya that she is Ladybug.
As of "Optigami" she is now a permanent holder of the Fox Miraculous. She also becomes Marinette's presumptive successor for the ownership of the Miracle Box.
During the events of "Sentibubbler", she creates an illusion of Ladybug, which claims that Alya would no longer use the Fox Miraculous, allowing Alya and her family to be freed from any future threats from Shadow Moth. This forces Alya to only use her Miraculous behind the scenes, at least until Shadow Moth is defeated.
In "Hack-San", Alya received the Ladybug Miraculous from Marinette when the latter needed to temporarily leave Paris with her parents to celebrate her aunt's birthday. When Robostus, together with the titular sentimonster, started wreaking havoc, she used the Miraculous, when inhabited by Tikki, to turn into **Scarabella**, a ladybug/scarab-themed superhero.
As of "Rocketear", after putting herself in a position where her hero persona could no longer be seen in public and where she could only assist her allies from the shadows, her costume changed and she decided that she was known as Rena Furtive, an arctic fox-themed superhero.
In "Strikeback", Alya willingly renounced herself after taking too many risks thanks to the effects of Risk and Carapace accidently exposing her in front of Shadow Moth while protecting her from Strikeback, as well as telling the truth to Nino about her being Rena Furtive, she returned the Fox Miraculous to Ladybug.
In "Transmission", in order to allow Marinette to be free to love Adrien, Alya was chosen by Tikki to temporarily wield the Ladybug Miraculous, thus becoming once more the superhero Scarabella.
In "Deflagration" after her secret identity as Scarabella was discovered by Monarch, he formulated a plan to take her Ladybug Miraculous, forcing her to give the Miraculous back to Marinette.
In "Revelation", after Alya was removed from Hoaxer's control by Marinette, she temporarily received the earrings as part of Marinette's plan to stop Hoaxer, once again becoming Scarabella.
In "Re-creation" after Marinette recovers the stolen Miraculous and reforges them following Monarch's defeat, Alya is given back the Fox Miraculous permanently and reunites with Trixx.
