Her weapons

Rena Rouge's flute

Lady Wifi's cellphone

Laser cannon (as Oblivio)

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

In "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 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 "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.

Appearance

Physical appearance

Alya is a Martiniquan Creole-French girl with the height of 5'5" and a curvaceous body. She has heart-shaped lips, hazel eyes, and a mole above her forehead. Her hair is wavy and reddish-brown ombre, growing slightly past her shoulders and having light copper-red tips.

Civilian attire

She wears black horn-rimmed glasses, with a white spot on each side. Her outfit consists of a white tank top underneath a short-sleeved plaid shirt with white, orange, and purple stripes; light blue jeans, and white sneakers with black tops. She wears a light red-colored lipstick.

As Rena Rouge

When transformed, Rena Rouge's hair turns longer, becomes a three-tone ombré, having the roots turn dark red/red-orange, mixing to orange with the tips being white, and she wears her hair back into a high ponytail with an orange headband. Her body is slimmer than her civilian form. The top layer of Rena Rouge's suit, akin to an overcoat, is orange with a white front, a black swan-necked collar, and black arms and gloves up to the middle of her upper arms. The overcoat layer attaches down the vertical front centre with a zipper, and the Fox Miraculous becomes the zipper. The overcoat also has a long fox tail-like coattail that ends a bit below her knees at a sharp white tip. The bottom layer of her suit is orange with a white center on the front of the body and black legs starting at a point in the middle of her upper legs. She also wears black boots with orange soles and black fox paw print markings. Rena Rouge wears an orange mask with a white bottom half and a black mark above each eye. Two orange fox ears with white insides, black tips, and black edges are attached to the top of her head. She attaches her flute diagonally on her back when it's not being used

Personality

Alya entertains Manon with a story.

Alya is rather energetic, ionate, and funny, confident, yet down to earth. Alya's foresight has come in handy many times. After Marinette thinks she accidentally lost a video of Ladybug on Alya's cellphone, she explains that she had already posted the video on her blog, mindful that something might go wrong when she showed her clumsy friend the video. When it comes to anything involving Ladybug and Cat Noir, she easily becomes very excited and basically has a single goal of updating her blog as soon as possible, such as when she is kidnapped by the Pharaoh to be a sacrifice yet still records herself and live streams the video on her blog. Sometimes, she goes too far, such as spying on Chloé's locker, which results in her getting punished by Mr. Damocles.

Alya doesn't like being undermined or doubted by others, especially when it comes to her work. If someone points out something wrong to her, she is too stubborn to it they are right. Though her research is generally right when she takes her time, Alya tends to jump to conclusions, like quickly suspecting Chloé of being Ladybug after seeing the girl with her own Ladybug suit and toy yo-yo and mistaking them for the real ones. She also has a habit of never checking her sources or doing ethical investigating of her blog posts, while demanding others to provide proof for their claims, even though she doesn't do that herself often.

Alya is extremely loyal, ive, helpful, and sometimes pushy, such as when she goes out of her way to encourage and (sometimes literally) push Marinette into spending time with Adrien. She is also very stubborn when it comes to doing things her way, such as the photo shoot of Marinette's fashion line. Another side to her is that she can be a bit demanding at times just as keeping Nino in line about revealing Marinette's crush on Adrien. Alya has a dramatic side to her personality, such as when she pretends to be a unicorn with Manon and later makes an excuse to Adrien's photographer, who asks her to be a model for Adrien, so Marinette can do the modelling instead. Having to babysit her younger siblings at home, she is great with kids, though sometimes she pushes her responsibility of watching them on Marinette so she can go on dates with Nino.

Alya disregards her safety to film Ladybug.

As described by Cat Noir in "The Pharaoh", Alya is a "brave chick", unafraid to get close to villains in her pursuit of the truth, tending to forget her safety at times and needing rescue by the very superheroes she is filming. As Ladybug, Marinette calls Alya bossy, feisty, and bold. Her bravery and determination has helped both civilians and superheroes, such as when she makes a plan with her classmates to save Marinette and sacrifices herself in the process or rides a bike to distract Gigantitan from harming Ladybug, showing a more comionate side towards her beloved ones in danger and great skills in leadership.

Alya is delighted when Ladybug presents her with the Fox Miraculous.

Alya holds great iration and respect for the two superheroes, especially Ladybug, wishing to know anything and everything about her. Much more, she wildly dreams of knowing Ladybug's identity, not once thinking about the consequences of posting the information on her blog, as Marinette pointed out to her in several episodes. However, she would respect her desire to keep it secret. Alya wishes to work alongside her, her dream coming true when the

superheroine chooses her to wield the Fox Miraculous and asks her for her help in defeating Sapotis. She greatly values the trust Ladybug has in her, making her someone of her word above her burning desire to continue helping her teammates and classmates

As Lady Wifi

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.

As Rena Rage

In "Mayura", Rena Rage has the same appearance as her superhero counterpart except for being red all over, owing to her having been taken over by a Scarlet Akuma. Her appearance resulting from a regular Akuma is unknown.

As Oblivio

Oblivio is a purple silhouette that has a laser cannon in its left hand and wears a gray glove on its right hand.

Rena Rouge assists Ladybug and Cat Noir.

As Rena Rouge, Alya retains most of her personality traits such as her undying loyalty, trustworthiness, and curiosity. She is ive of her allies, whom she gets very excited about working with, causing her to be a bit of a scatterbrain. A fast learner, she takes quickly to her abilities.

As Lady Wifi, her desire for answers increases considerably. Despising Ladybug's secrecy, she will stop at nothing to find out her secret identity, even if it means exposing a horrible person underneath, such as when she believes that Chloé is Ladybug. Her speediness to update onlookers remains the same, but her methods for finding info become sneakier than her normal self.

As Rena Rage, her personality as Rena Rouge seems to inverse, making her cruel and aggressive.

As Oblivio, she wants nothing more than to erase the memories of everyone in Paris.

Abilities

As a civilian

Alya filming Ladybug for her blog.

Alya is very tech-savvy, keeping up the school blog and Ladyblog with ease, ing videos and streaming live recordings. She records with her cellphone and knows how to videos from it. Judging from her Instagram photos, she is also quick with a camera, taking many photos of Ladybug and Marinette without being noticed until the heroine spotted her first.

She also can use applications to see more aspects of pictures than can be seen at first sight. In "Startrain", she started a blog about astronomy.

Aside from that skill, Alya is a very good writer, composing several articles for her blogs and penning the script for Nino's film in "Horrificator". Observant and a quick thinker, Alya has figured out a lot of things about Ladybug, Cat Noir, their Miraculouses, and the villains they fight from watching them. Even before becoming a regular superhero, she knew about their time limit and the Akuma-corrupted objects.  She quickly deduced that the kwamis are the power source of their powers. While not knowing that her best friend is Ladybug, Alya guessed correctly the identities of Carapace and Cat Noir, though is apparently not sure about the latter.

Her observation skills and previous knowledge allowed her to discover the existence of previous Miraculous holders and the Order of the Guardians.

Likewise, Alya excels at presenting herself in her videos, explaining situations when needed and usually keeping her cool if the situation gets dangerous, as with the Pharaoh. Alya quickly developed great acrobation skills even in her civilian form, showing great synchronization with Nino while doing this. Alya showed the same coordination skills at dancing with him and she also is good at rapping. She is learning how to cook from her mother.

As Rena Rouge

Rena Rouge has enhanced skills, such as speed, strength, and resistance. Her most prominent physical skill is agility, jumping to heights that Ladybug and Cat Noir cannot. Like a fox, she also has enhanced senses such as hearing, smell, and night vision.

Rena Rouge uses her flute as her weapon, being able to use it to deflect attacks and throw it with great precision.

Rena Rouge plays her flute.

Her special power, Mirage, is executed by playing her flute to produce an orange ball of energy at the far end of it. Wherever she throws the ball of energy, it creates a hyper-realistic illusion. However, the illusion disappears if it is touched. Although Mirage is handy to use, Rena Rouge must use it wisely, as she can only use it once before reverting to her civilian form five minutes after using it.

As Rena Rage

She retains the same ability as Rena Rouge, as well as the same weapon.

As Lady Wifi

Lady WiFi throws her pause icon.

A Wi-Fi signal gives Lady Wifi power, but if the signal is too weak or nonexistent, she loses her abilities. She uses her cellphone, which is the Akumatized object, as her weapon. Swiping her phone, she can shoot out glowing pink icons, to wit:

The pause and stop icons, which can freeze people.

The padlock icon, which can lock doors, and bind body parts to a surface.

The camera icon, which she uses to film and broadcast videos that she can project in the sky and on all available screens.

The fast forward icon, which acts like a hoverboard as a mode of transportation. This is first shown in "The Puppeteer".

Lady Wifi is also able to dispel any of the currently in-use icons by crossing them off using her cellphone. Additionally, Lady Wifi can teleport herself using cell phones and antennas.

In "Félix", Alya's tablet becomes Lady Wifi's new weapon and, because of her satellite connection, her previous weakness regarding the existence of Wi-Fi signal is removed.

Even without her phone abilities, Lady Wifi is skilled in hand-to-hand combat, easily being able to pin Cat Noir down on the ground. She is also shown to be remarkably strong, easily lifting an entire wooden chest and throwing it across the room at Ladybug.

As Oblivio

Oblivio has super strength and wields a laser cannon that can fire a blast of purple energy that causes whoever it hits to lose their memories.
