—Marinette, "Ladybug and Cat Noir (Origins - Part 1)"
Marinette Dupain-Cheng is one of the main protagonists of Miraculous: Tales of Ladybug & Cat Noir. Marinette is a student in Miss Bustier's class at Collège Françoise Dupont in Paris, France. She is also a budding fashion designer. With the Ladybug Miraculous, when inhabited by Tikki, Marinette transforms into the superheroine Ladybug, gaining the power of good luck and creation to stop Hawk Moth and his Akumatized villains.
Marinette is half French and half Chinese. She has bluebell eyes and medium-length black hair with blue reflections. She usually wears her hair back in two pigtails. She also has some freckles on both sides of her nose and a few on the bridge.
She wears a dark gray blazer with rolled up sleeves. The inside of the blazer is lined in white with pink polka dots, and it has black trimming. Underneath, Marinette wears a white t-shirt with black stitching and a flower design below the collar. The design itself has pink flowers and black leaves. She wears rolled up pink jeggings with the inside lined in white with pink polka dots as well. Light pink ballet flat shoes with dark red soles adorn her feet. She also wears her earrings (that also serve as her Miraculous), which are black when not inhabited by Tikki. Often, she wears a light pink purse with a thin black strap over her right shoulder.
Ladybug wears a red skintight bodysuit covered in black spots and with a black collar. When not in use, she keeps her yo-yo around her hips with a red string. On her face is a red mask with five black spots that are in a symmetrical design, and the waterlines of her eyes are colored black. Her earrings are red with five black spots in a quincunx pattern and the bands holding her hair back become red ribbons, resembling a ladybug's wings when it's flying.
As Ladybug in Aqua FormWhen accessing her aqua powers Ladybug's pigtails becoming longer and have a pink sombre to the ends of them. Ladybug's hair ties become longer and pink. Ladybug's suit remains mostly the same in its basic structure but gains a silvery scale pattern on it and the mask. The collar becomes a light pink and has a split in the middle. The suit also has pink flippers on the feet and fins on the forearms. Around the waist are accents like the flippers and a circle symbol that looks like the Ladybug Miraculous in its active form.
Marinette is sweet, outgoing, joyful, and a bit awkward and clumsy. She loves fashion, her friends, family, and her crush Adrien. Despite her outgoing and empathetic personality, Marinette struggles with self-confidence and self-esteem: In a situation, she deems urgent, like doing something for Adrien or losing something that will expose her secret identity, she becomes very nervous, awkward, and quick to panic. Marinette cares deeply for other people, usually putting their feelings and interests even before her own, in some cases at a personal cost. Despite being genuinely kind, she has her limits, such as in "The Evillustrator" when she gets irritated with Chloé to the point that she refuses to continue guarding her from The Evillustrator as Ladybug.Marinette can act impulsively and irrationally at times, as shown when she tried to deflect the false accusation of "stealing" Chloé's bracelet onto others who are also innocent. She also expresses jealousy whenever other girls such as Chloé or Lila flirt with Adrien, sometimes causing her to act irrationally, even abusing her powers as Ladybug to keep them away. However, she tends to learn from her mistakes and become a more open-minded, understanding person. Although she is absent-minded and acts before thinking at times, Marinette is clever, showing when she hid her signature in her when Chloé stole her design, thus exposing her. Furthermore, she is willing to do a number of risky tasks in order to protect her identity and image, like stealing Adrien's phone in "Copycat" to erase an embarrassing message she accidentally left on it. Thanks to her confidence as Ladybug, she's gotten more calm and comfortable around Adrien as herself. Seen in "Gorizilla", as she tried to help him get away from a swarm of fans and is able to talk to him more fluently.
As Ladybug, Marinette retains many of her alter ego's characteristics, but she is much stronger. Her confidence and bravery come out more prominently. Her quick-thinking, resourcefulness, and wits are more obvious, especially when she is figuring out how to utilize her Lucky Charm. As Ladybug, Marinette strives to rescue everyone, including those akumatized by Hawk Moth. No matter the difficulty of her tasks, she does everything in her power to set things right while keeping up with her everyday responsibilities, like designing something or working in the bakery. Like Cat Noir, Ladybug is clever with her words and occasionally enjoys making puns. She has a more serious side when fighting against Hawk Moth's villains, as opposed to Cat Noir's laid back and goofy personality. At times, she enjoys teasing him and others, while she can get exasperated, she handles joking calmly. As her alter ego, Marinette strives to keep her personal and superhero lives separate to protect herself, the people she knows or she is close to. She is also great at giving advice to others when they need it. With her greater confidence, she aims to be honest with others in other ways, like her honesty with Cat Noir about not having romantic feelings for him.Also as Ladybug, Marinette has the people's loyalty, respect, trust and help when she needs it.
As a civilianFor a list of things made by Marinette, see the List of Marinette's creations.
Marinette has talent in fashion design, being able to sketch ideas in a notebook after getting inspired by certain surroundings or topics, and sewing by hand or with a machine. Using computer software to create graphic designs is also an ability she possesses for creating things, such as albums covers. She wears her own creations like her little purse, and also makes things for others, such as the bakery's logo, Adrien's scarf and Jagged Stone's glasses. Her skills in this field are exceptional for an amateur, such as when her pigeon-styled derby hat that she made was good enough to be recognized by the famous professional designer Gabriel, despite the fact she had never made one before. Marinette is also very skilled at video games, easily beating Max at Ultimate Mecha Strike III and getting the highest score in the entire school.
Marinette has high stamina, endurance, and agility, even in her civilian form, as displayed in "Timebreaker". Marinette can also run long distances without stopping, as seen in several episodes. She is also quite stealthy, as she frequently sneaks up on Adrien, and other people without being noticed. As complemented by Adrien in "Despair Bear ", Marinette is an excellent dancer and baker. In "Riposte ", Marinette has good reflexes being on par with Adrien despite fencing for the first time.
Ladybug has much more enhanced skills, such as speed, agility, and strength, and she is almost invulnerable to physical damage. She has remarkable talent with wielding her yo-yo, like using it as a grappling hook, a rope to restrain others, a projectile, and even a shield if she spins it fast enough. After an evil akuma is released from its corrupted object, she can open her yo-yo, throw it to grab it, and remove the energy charged it with, releasing it as a normal butterfly. She is skilled in hand to hand combat when fighting villains or Cat Noir when he ends up being controlled by one.
Her special power, Lucky Charm, helps her by summoning an object that she uses to achieve her objective, it often being to stop a villain. Though usually confused at first, her creativity and cleverness help enable her to perceive where the object can be used to help her achieve her goal, thinking up ideas and plans on her own.  However, Lucky Charm drains her power and reverts her back to Marinette shortly afterward, so she has to use it wisely. Once the villain is dealt with, Ladybug can throw her Lucky Charm object into the air and use the Miraculous Ladybug, which will make it revert back to energy and fix all of the damage done since the villain was created.
As Ladybug in Aqua FormWhen accessing her aqua powers, Ladybug has the ability to breathe underwater and enhanced swimming capabilities. When her belt buckle is detached it can work as breathing apparatus for someone that can't breathe underwater as seen with Kim in "Syren".
= Gender Unknown
- The lineage of Sabine Cheng's parents and uncle is uncertain.
- In China, wives do not usually take on their husband's surname, keeping their own. Children usually take the father's surname.
- During a 2018 Miraculous panel at Ludicomix, Thomas Astruc reveals that Marinette has a grandfather but it's currently unknown if he's from Tom's or Sabine's side.
Marinette first meets Adrien when both are their alter egos in "Ladybug & Cat Noir". She gets a bit frustrated with him a few times, like when he carelessly uses his Cataclysm, but she likes him as a partner and works well with him. In Stoneheart, when she admits it is her fault for not purifying the akuma the first time, she is both surprised and grateful for Cat Noir's encouragement. After saving the day, she doesn't react to Cat Noir's flirting and bids him farewell.
In the same episodes, she first hears about Adrien from Chloé, but she doesn't know who he is. The next day, she meets Adrien at school, but she quickly becomes disgusted of him when it looks like he put a piece of gum on her chair, unaware that Chloé placed it there and he was trying to remove it. She recognizes that he is the son of Gabriel Agreste, her favorite fashion designer, from Alya, but it doesn't change her dislike of him. After school the following day, though, he finds her stuck at the school's gate because of the rain, so he manages to explain the situation with the gum and gives her his umbrella. She then realizes he is nothing like Chloé and sees his gentle, caring side, and befriends him.
After that, Marinette develops a "secret" crush on Adrien. On the walls of her room and in several photo frames are pictures of him from various magazines. She often daydreams about him and longs to win his heart, but her awkwardness around him makes it a great challenge for her. However, Marinette has prioritized Adrien's happiness over her own. On Adrien's birthday in "The Bubbler", she accepts the fact that Adrien thinks her gift is from his father because he is so pleased to have gotten such a gift from him, deeming his happiness more important than hers. Gradually, in later episodes such as "Kung Food" and "Gamer", Marinette becomes more comfortable and confident around him, being able to speak normally with him and express herself. While she still freezes up around him often, she builds a friendship with him while still having feelings for him, including moments like dancing with him in "Despair Bear" at Chloé's party. In "Gorizilla", while hiding with him she stuttered on the idea of being Adrien's girlfriend and got to spend a little time with him at the theaters.
Her feelings for him can cause her issues, whether unable to stay relaxed and rational around or about him. She does get upset whenever he cannot come to hang out with their friends, but does not give up. In "Simon Says", while trying to defend everyone at the Agreste mansion, Marinette briefly stammers and stutters around Adrien or when talking about him as Ladybug. In "Volpina", she harshly lashes out at Lila and her deceitful nature as Ladybug and in front of Adrien, due to being jealous that Lila is trying to get Adrien's attention. Later, when she and Cat Noir are fighting Lila's akumatized form, Volpina, she nearly gives up her Miraculous when she believes that Lila has taken Adrien hostage and plans to drop him off the Eiffel Tower, not realizing that it's an illusion. She keeps her jealously under more control while trying to keep Adrien protected in "Riposte". Also in "Gorizilla", she showed more determination and calmness when protecting Adrien from the villain.
When it comes to Cat Noir, Ladybug sees him as a worthy partner in fighting crime, caring for him greatly. This is seen in the webisode Cat Noir as seen by Marinette, when she says that she doesn't think she'd defeat all the akumatized villains without him.
While he constantly flirts with her, Ladybug mostly sidesteps his romantic gestures and often gets annoyed with him if the moment is inappropriate (like when they're fighting a villain), though she does display a little bit of affection towards him occasionally. In "Gigantitan", she compliments on Cat Noir's cleverness on dealing with the titular villain. Despite their teasing relationship, the two are a great team: they have a lot of faith and trust in the other, greatly support the other, and are willing to risk their lives for their partner. She trusted him not to look when they detransformed in "The Dark Owl". Another example of that faith and trust is seen in "Gorizilla", when she trusted Cat Noir to arrive when she needed him. She is aware that Cat Noir wants to know her secret identity, but thinks it is better if no one knows for the sake of protecting humanity, and each other.
In "The Evillustrator", when Cat Noir arrives to discuss stopping the villain with Marinette, he introduces himself in a flirty manner, and she mocks him by "mouthing" words with her hands as he shows off. But she does smile and giggle to herself after he leaves. In the webisode "Cat Noir as seen by Marinette", Marinette says that she might see Cat Noir differently if Adrien did not exist, though she immediately dismisses the thought because she doesn't want to think of a world without Adrien. Before she can transform in "Befana", Cat Noir comes to take her somewhere safe, commenting on how she must be a nice girl to have such loyal friends, and wishes her a happy birthday (although he already did earlier, but as Adrien). During "Glaciator", after they both discuss their issues with their romantic endeavors, Marinette notices Cat Noir's affectionate and sensitive side, and realizes that his feelings for Ladybug are genuine. However, she doesn't want to disappoint Cat Noir and play with his feelings, so she tells him earnestly as Ladybug that she views him as a close friend, not just a partner, but that she has her heart set on someone else. She also blushes after he kisses her on her cheek.
Marinette's kwami, Tikki, allows her to transform into Ladybug. When she sees her for the first time in "Ladybug & Cat Noir", Marinette is terrified, thinking Tikki is a "bug-mouse". She throws several things at her, trying to scare her off. Eventually, Marinette listens to Tikki's information and reluctantly transforms with her for the first time. After defeating Stoneheart, she learns that she failed to purify the akuma and made the situation worse, and despite Tikki encouraging her to keep going, Marinette apologizes to her and puts her away with the Miraculous. It isn't until Stoneheart's next attack that Marinette decides to be Ladybug again, and she puts on the Miraculous again, telling a delighted Tikki that she won't sit back and do nothing when others are in trouble.
They have a good relationship as partners and friends, often nuzzling each other warmly and even playing on occasion. Marinette appreciates Tikki's attempts to cheer her up after she has "failed" with Adrien or displayed "incompetence" as Ladybug. Tikki also helps Marinette when she doesn't feel confident in herself, or when she gets off track, and often gives her advice. In "Princess Fragrance", when Tikki gets sick and taken by Chloé, Marinette is desperate to find her and take her to the healer. Once she finds her, Marinette rejects Tikki's suggestion that they transform to stop the titular villain, saying she won't make the same mistake twice and went to see the healer right away. She tells Tikki after she is healed that she is more than a kwami to her.
Marinette treats Gabriel with respect, knowing how formal and strict he can be as Adrien's father. But she does also admire his work as a fashion designer, and hopes to be on good terms with him.
With Hawk Moth, however, she is fully aware that he is the culprit for the akumas, and supervillains, though she has never met him in person. She always works very hard to stop him, not wanting him to win by taking her Miraculous.
In "Stoneheart (Origins - Part 2)", Ladybug and Cat Noir are introduced to Hawk Moth when akumas form a large version of his head while the two heroes are fighting Stoneheart at the Eiffel Tower. Rather than being intimidated, Ladybug confidently warns Hawk Moth that she and Cat Noir will find him, and he'll be the one giving them his Miraculous.
In "The Collector", through deductive reasoning Marinette concludes that Hawk Moth secret identity is Gabriel Agreste. But she is thrown off his trail when he akumatizes himself, after he is saved Marinette has no idea that she was unknowingly correct. After learning about the Ladybug and Cat Miraculouses' combined wishing power from Wang Fu in "Robostus", she agrees that Hawk Moth must not get access to her and Cat Noir's Miraculouses, and she understands Wang's warning in "Sapotis" that Hawk Moth getting more Miraculouses would be dangerous.
Marinette is forced to sit next to Alya by Chloé on the first day of school in "Ladybug & Cat Noir", but after Alya stands up for her, Marinette befriends her quickly. When she decides to not be Ladybug in "Stoneheart", she plans to give the Ladybug Miraculous to Alya by slipping it into her bag at school. However, when Alya is pinned to a wall by a car and cries out for help, Marinette, who was taking Alya's bag to her after she left it to watch the fight, becomes determined to save her and takes out the Miraculous to use again. The next day at school, Alya reveals her plans to find out Ladybug's secret identity, while Marinette knowingly tells her, "Good luck with that."
Marinette enjoys spending time with Alya, her best friend. They get along very well, both tolerant of each other's flaws, like Marinette's ditziness, and Alya's pushiness. Although often frozen with fear whenever Alya assists her with doing something with or for Adrien, Marinette is thankful for her pushing her forward. Alya's desire to find out more about Ladybug and her secret identity has caused many problems for Marinette, who wants to let Alya know that she is Ladybug but can't. She panics when Alya finds the history book she dropped as Ladybug in "The Pharaoh", and she is utterly astounded when Alya leaves her a note saying she knows who Ladybug is in "Lady Wifi". Alya's attempts to find the truth about Ladybug can be exasperating for Marinette, but she does her best to conceal her identity from her. Both find Chloé awful, and both support each other in any way that they can.
In "Sapotis ", Marinette is staying the night at Alya's apartment. When Alya's younger sisters get akumatized, but realizes that she and Cat Noir can no longer fight alone, so Master Wang Fu gives Marinette the Fox Miraculous to hand out to a trustworthy candidate. Marinette approaches Alya as Ladybug and gives her the Fox Miraculous to temporarily assist her and Cat Noir to defeat Sapotis. While working with her, she notices that Rena Rouge becomes easily wrapped up in the excitement, so she has to remind her to stay on track. Ladybug likes working with Rena Rouge, and she understands how much Alya enjoys being a superhero. Nonetheless, being obedient to Wang Fu's requirements, she keeps Alya to her word on returning the Fox Miraculous and gets exasperated by Alya unwilling to give it back. Knowing Alya would make the right choice, Marinette is glad that she returns the Miraculous.
Whenever she is with her parents, Marinette is shown to love them and support them, just like they do. Sometimes, she helps them at the bakery, like finishing an order, or designing a logo for their business. When the Bubbler's bubbles take her parents away, Marinette deeply desires to save them and all of the parents. She often plays video games, such as Ultimate Mecha Strike III, with her father. She does feel bad about making up excuses to them when she has to be Ladybug, and is upset when they grounded her for missing classes, but knows they only mean well. Also during Animan's search for Kim Marinette almost loses her cool as Ladybug but thanks them for their help nonetheless.
In "Despair Bear", Marinette likes it when her father comes to her school to give her class cooking lessons.
Marinette has been in the same class with Chloé for four years, and she was always being bullied by her. On the first day, Marinette is frustrated that Chloé and Sabrina force her out of her seat, but she doesn't protest. Alya encourages her to stand up against her, but it isn't until the end of "Stoneheart" that Marinette, now full of confidence, calls out Chloé for her awful actions and tells her to take her attitude and sit somewhere else.
Marinette despises Chloé. She hates how Chloé mistreats everyone, including her "best friend," Sabrina. As Chloé's main target, she constantly deals with Chloé's despicable attitude towards her. Chloé's love for Ladybug doesn't change Marinette's attitude – making her annoyed over watching after or protecting her. Considering Chloé to be her rival for Adrien's affection, she doesn't like how she is always throwing herself at him, at one time using her Lucky Charm out of jealousy to prevent her from kissing Adrien while slow dancing. Nevertheless, Marinette deals with Chloé with occasional thrilling success, such as the time she reveals that Chloé stole her derby hat design by revealing a unique design on it that proved the hat is actually hers.
In "Despair Bear", she is annoyed when Chloé disrupts her father's cooking lesson. When Chloé invites all their classmates to a party, Marinette is skeptical. Later on, as Ladybug she appreciates Chloé's assistance in stopping Despair Bear, but she agrees with Adrien that Chloé will probably never fully change when she reverts from kindness towards her classmates to criticizing them again.
Marinette isn't close to Sabrina, but she feels bad that Chloé abuses her so unfairly. In "The Evillustrator", when she stands up for Sabrina, she is surprised that Sabrina immediately tries to befriend her, including doing her geography homework for her, much to her discomfort. Because she agrees to go to a party with the Evillustrator in order to defeat him, she sadly tells Sabrina that working on the presentation later at night won't work, which greatly upsets Sabrina, and she is hurt when Sabrina accuses her of being just like Chloé. After that, Sabrina usually follows Chloé in bullying Marinette, which upsets her. But on occasion, Marinette does show kindness to Sabrina, such as when she frees her hand from the magic box in "Darkblade" and in "A Christmas Special" when she gives her a Christmas log.
Marinette and Nino get along well as friends. She never realizes he had a crush on her in "Animan" until he admits it after it's gone, but when they're at the park and he lies that he needs help getting together with Alya, Marinette is excited and eager to bring him and her best friend together. In "Simon Says", she is invited to see him perform on The Challenge, but she is grounded by her parents. On occasion, she can get a bit annoyed with him, like with his filming enthusiasm in "Horrificator". As Ladybug, Nino admires her for saving Paris, and is excited whenever her and Cat Noir are around. He even invites them as his special guests for The Challenge, saying they wouldn't let him down.
When they first meet, Marinette, unaware of Master Wang Fu's importance as the Great Guardian, saves him from oncoming traffic in "Ladybug & Cat Noir". She brushes off dropping a box of macarons in order to rescue him and tells him to have a nice day as she runs to school. Later, when she takes Tikki to him to get healed in "Princess Fragrance", she worries about keeping Tikki's species a secret from him, but she shows immense gratitude to him for healing Tikki, although curious about how he did it.
In awe of Tikki's seriousness about the Great Guardian and his need of the Miraculous spellbook, Marinette officially meets Wang Fu in "The Collector". Despite understanding his importance and agreeing to help him stop Hawk Moth, she struggles to trust him and tell him everything she knows when evidence points to Adrien being Hawk Moth's secret identity. She finally opens up to him after she figures out that neither Adrien or his father are Hawk Moth—unaware that Gabriel tricked her—and she agrees to be honest with him about her feelings and information she gathers. From there, she continues to visit him and views him as her teacher, patiently listening to his knowledge and asking questions whenever confused or curious. His teasing flusters her at times, becoming embarrassed when he guesses her initial unwillingness to tell him about where she found the book is because of someone she loves. Meanwhile, she shares his determination to retrieve the Moth Miraculous from Hawk Moth and restore balance to the universe before the Ladybug Miraculous and Cat Miraculous are used to make reality-bending wishes. In "Sapotis", she also is respectful and obedient to Wang's request to be careful with the Miraculous she takes out by making the right choice for a user and getting it back to Wang Fu afterwards.
Manon, being a child with an energetic and outgoing personality is tiring for Marinette, who doesn't have experience with having siblings or skill with bonding with younger children. No matter how exhausting it is to take care of Manon, Marinette does care for her and her safety, promising to her as Ladybug that she'll save her and Alya from the ice dome they're trapped in and trying to change her back to normal when she is turned into the Puppeteer by Hawk Moth. She will often call Alya to help her babysit Manon, as seen in the episode "Prime Queen", as Alya helped on that day and the day after.
Being friends with Rose since at least the previous school year, Marinette likes hanging out with her, and she encourages and supports her when needed. To cheer Rose up in "The Notebook", Marinette compliments her journal and draws a picture of a rose in Rose's journal.
In "Gigantitan", she is surprised that Rose and the others already know of Marinette's crush on Adrien and approves of it. She appreciates Rose's support during the girls' plans to set up her with Adrien, and as Ladybug, she praises her for helping her out of the villain's grip.
Juleka is also one of Marinette's friends since at least the previous school year, and Marinette cares for her, even though she sometimes is hard to understand due to her shyness. In "Reflekta", Marinette is determined to help Juleka get a good photo of herself, driven enough to defy Chloé and Sabrina's efforts of ruining Juleka's chances of being in the class photo.
She is surprised that Juleka reveals she knows that she has a crush on Adrien in "Gigantitan", but she is thankful for Juleka's support and encouragement. She praises Juleka while being Ladybug for helping her get free from Gigantitan.
Being Mylène's friend and classmate, Marinette enjoys hanging out with her, and she supports her in any way possible, vouching for Mylène's role in the movie in "Horrificator". As Ladybug, she also helped her and Ivan become a couple.
In "Gigantitan", Mylène's knowledge of Marinette's crush on Adrien is a shock to Marinette, but she cherishes Mylène's willingness to her try to get together with Adrien and, when fighting as Ladybug, helping distract Gigantitan so she can escape.
Marinette views Alix as a friend, cheering her on during a race against Kim in "Timebreaker" and feeling terrible for her watch getting broken.
Alix knowing about her attraction to Adrien surprises her, but she is grateful for Alix's assistance with Alya's plan to get her and Adrien together.
Marinette and Kim are friends, having known each other since at least the previous year at school. In "Animan", he asks her if she'd like to join him and Max at the zoo, but she politely declines since she came with Alya and was waiting for Nino and Adrien. He is surprised at her skills in "Gamer", as she was able to beat Max's score. She also encourages him to give his crush his gift in "Dark Cupid", which he appreciates, although she is unaware his crush is Chloé.She shows great concern for him in "Befana", when he gets turned into a coal statue sacrificing himself to save her.
In "My Birthday Party", Marinette admits that Ivan is a "bit of an old grump," but he is nice to her, which she appreciates. When she realizes that Ivan has feelings for Mylène that he is scared to act on in "Ladybug & Cat Noir" and "Stoneheart", she encourages him to tell her how he feels, believing the two were made for each other but weren't aware of it yet. She is happy for them after she shares Ivan's song lyrics with Mylène, who responds warmly.
Marinette is friends with Nathaniel since at least the previous school year and thinks he is an excellent artist, but she never expected him to have a crush on her until Chloé reveals it to everyone in "The Evillustrator". She agrees with him (while he is Evillustrator) that Chloé is egotistical and mean, and she gets frustrated when he accuses her of being just like Chloé after she reveals that she teamed up with Cat Noir to stop him. Nathaniel is temporarily upset at her accusing others, including himself, of stealing Chloé's bracelet in the episode "Rogercop", but Marinette did not mean to hurt anyone's feelings. In "My Birthday Party", she does not mention Nathaniel, but he is invited to her birthday party in "Befana", and works with their friends to protect her.
Marinette hears about Lila being a new student from Alya, and when she sees Lila flirting with Adrien, she becomes jealous and upset. She spies on the two in the library and gets angry when she hears Lila lie to Adrien and say that she is friends with Ladybug. In addition, Lila states that she is more powerful and celebrated than Ladybug. Later at the park, when Lila attempts to lie to Adrien about being a Fox Miraculous holder, Marinette transforms into Ladybug and calls out Lila on all her lies, making her cry and run away, her chances with Adrien shattered. Ladybug eventually regrets her harsh treatment of Lila and uncontrolled jealousy after she realizes that Volpina, whom she was jealous and suspicious of, is the akumatized Lila. Once Volpina is defeated, Ladybug apologizes to Lila for her actions, only to have her apology be rejected, with Lila saying they would never be friends, as Ladybug had said earlier on.
Marinette loves her grandmother, but because she rarely sees her, she tries her best to please her when she visits, like pretending to like candies that Gina gives to her. Gina's view of Marinette as a younger girl is exasperating to Marinette, but she feels bad when she realizes that she upset her grandmother by leaving her for her surprise birthday. As she later tells Gina, while pleased that she is recognizing her as having grown up, she legitimately enjoys hanging out with her, knowing anytime with them together is memorable.
Marinette immediately recognizes Kagami's talent when she and Adrien start dueling in "Riposte", and she is as surprised as Adrien to find out Kagami is a female. Albeit very minor, she exhibits jealousy about both Kagami's skill and her gender in relation to Adrien when dealing with her akumatization as Riposte. Unsure of her call on Adrien and Kagami's match, she regrets making it as she sees Kagami's defeated reaction. Once Kagami is brought back to normal from her akumatization, Ladybug supports Adrien in apologizing to her by giving Kagami's saber to him, and bears no ill toward her.
Marinette and Luka first meet in "Captain Hardrock". At first, Marinette is startled by him and stutters when she speaks to him. He teases her playfully about her stuttering but immediately regrets it when she frowns, embarrassed. She then begins to warm up to him as she listens to him play the guitar. As a memento, he gives her a guitar pick of Jagged Stone, which she accepts, calling her a 'funny girl.' Alya notices Marinette's interest in Luka and teases her about it, although Marinette denies it. Luka later compliments Marinette when he calls her 'incredibly brave' and Marinette, as Ladybug, blushes at his comment.

- Ladybugs are known to be symbols of good luck, especially in regards to love, as said by Alya in Dark Cupid.
- Thomas Astruc created Ladybug around 2005 when he was exchanging drawings on post-it notes with another worker and made one with the superheroine.
- In the fake comic book covers of The Mini Menace Ladybug, Marinette's name was Marietta.
- Marinette's design changed from the Ladybug PV version. Her anime design included jean shorts, and as Ladybug, she had a red-orange face mask without black spots and two long red-orange ribbons attached to each pigtail. She also had longer hair and lacked freckles.
- In the PV, Marinette's earrings were always red with five spots, no matter if she was Ladybug or Marinette. She only wore them as a civilian when needing to transform, not having them in public.
- PV Ladybug's costume differs from the CGI Ladybug as well, with PV Ladybug's spots being found only on her torso (her legs and feet were completely red) and wearing a ladybug-themed bag instead of having the yo-yo. PV Ladybug's hair and hair ribbons are also significantly longer than the current version of Ladybug, and she has an ahoge, which means "foolish hair" in Japanese.
- The yo-yo didn't exist; PV Ladybug fought using hand-to-hand combat.
- Her anime version was less shy around her crush, as she's able to be very close to Félix without panicking or being nervous. She even asks him out while slightly blushing and looking right at him, although Félix coldly refuses.
- Marinette's CGI design seems to have gone through a change as well. Earlier footage and images of Marinette included dark blueish-black hair, red tips of hair at the end of her pigtails, and gray eyes.
- In a placeholder animation, Ladybug was seen wielding a sword. Whether or not this was to be used as a new weapon or a Lucky Charm object is unknown.
- During the earlier stages of development, Ladybug wasn't allowed to abuse her powers of good luck, or else something bad would happen to her. As of now, it is unknown if Ladybug still has this issue, since, as seen in "The Bubbler", all that happens when she selfishly uses Lucky Charm is that she runs out of power and loses her transformation.
- In the English version, the pronunciation of the name Marinette with "mar" as in "marinade" is used, and in French, and other countries, the pronunciation with "mar" as in "market" is used.
- The first part of her last name, "Dupain," comes from the French words "du pain," which means "of the bread" or "some bread." This is a reference to her father's job as a baker.
- "Marinette" translates as "little Mary"
- "Cheng," the second part of her last name, translates as "to make", "become", "succeed", or "capable".
- Her responsibilities as a superhero not only include fighting akumatized villains but also patrolling and many other things.
- Marinette is right-handed, but this changes depending on animation errors.
- In "Stormy Weather", Marinette's infatuation with Adrien is revealed to even include plans for a family. The names of their supposed children are Hugo, Emma, and Louis—all traditional French names. Aside from these, she also appears fond of dogs and especially hamsters.
- She briefly considers a black cat as well, but she rejects the idea.
- Although not having any romantic feelings towards Cat Noir, in the webisode "Cat Noir as seen by Marinette", Marinette reveals that she's aware he may have a crush on her, and she admits she might have given him a chance if Adrien hadn't been around.
- In the Korean and French dubs of "The Pharaoh", Alya says that Ladybug might be a 9th grader, while in the English dub of the episode she says she might be a 10th grader.
- Ladybug's legacy is over 5,000 years old, as revealed in "The Pharaoh".
- Marinette is naturally flexible, being even more flexible as Ladybug because of her enhanced physical abilities.
- Marinette's hair color is an homage to old comic books that would use blue highlights on black hair.
- Marinette has stolen both Adrien's and Alya's phones during the series. Ironically, however, both thefts were unintentional and involved her trying to hide a fact from the respective owners.
- She has also stolen and returned Chloé's phone.
- Marinette sleeps with her pigtails on, as seen in the opening of "The Bubbler" and the ending of "The Pharaoh".
- Thomas noted that Marinette would be hard to akumatize, as she is an optimistic person.
- More of Marinette's Chinese heritage will be seen in the future.
- Thomas revealed on Twitter that Marinette and Adrien will be seen as a "real couple" at some point in the show.
- In "Gorizilla", she was referred to as Adrien's girlfriend.
- Marinette is the third known person of French origins to wield the Ladybug Miraculous, succeeding her predecessors, Jeanne d'Arc and La Coccinelle.
- Also Marinette is the second person of Chinese origins to wield the Ladybug Miraculous, succeeding her predecessor Ancient Chinese Ladybug Miraculous holder.
- In "Puppeteer", it's revealed that Marinette can whistle.
- A fan asked Thomas why he gave Marinette ballet shoes, to which he jokingly responded with: "Because with ski boots, you end up with stinking feet, and in addition it scratches the floor.".
- Thomas confirmed that at some point in the future, Marinette will be seen with her hair down.
- The way she throws her yo-yo in some episodes is similar to a baseball pitcher.
- The way she would hang upside down with her yo-yo is similar to Spiderman when he hangs from his webs.
- Like Wang Fu, she is the only person that knows Rena Rouge's secret identity because she gave her the Fox Miraculous.
- In "Gorizilla," Marinette reveals she hates horror movies.
- She was almost akumatized in "Zombizou," but was not due to her negative emotions having faded away before the akuma could infect an object of hers.
- In "Troublemaker", her identity was nearly revealed in front of Cat Noir by the titular character.
