Marinette Dupain-Cheng/Relationships

Manon Chamack
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.

Mylène Haprèle
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. She does enjoy hanging out with her on several occasions, like in "Gorizilla" and "Captain Hardrock".

She comments in "Friends" that she finds Mylène expressive with her feelings.

Alix Kubdel
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. She does enjoy hanging out with her on several occasions, like in "Syren" and "Frightningale".

In "Friends", she states that Alix is very brave, being the type who never backs down from a challenge.

As Ladybug, she accepted Alix's help in "Reverser", on stopping the villain with her clumsiness making it difficult to fight.

Lê Chiến Kim
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 whenever he is in danger, such as in in "Befana", when he gets turned into a coal statue after sacrificing himself to save her.

Ivan Bruel
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.

Lila Rossi
{{Scroll| 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.

{{HideSpoiler|In "Chameleon", Ladybug can finally vouched that she saved her life and proposes that they be friends and was happy that Lila accepted but unknown to her that it was a lie.}}

In "Catalyst", when Lila lies to Miss Bustier's class about being in the kingdom of Achu and having been invited by Prince Ali to his palace, Marinette attempts to expose this lie by pointing out that Prince Ali is in the USA, but she is frustrated with Lila deflects the truth once again. Marinette vows to expose Lila's true nature one day.

{{HideSpoiler|In "Chameleon", Marinette chews Lila out for her deceitful nature she retorts her by giving her a choice either that Marinette was with her or against. If it was against her Lila would then turn everyone against her, mortified at what she tried to do Marinette called her even more evil than Chloe and started to cry. Which led her to nearly being akuamtized but she manages to avoid it. However, she finds out from Lila that the two are at war and that she'll make Marinette lose her friends and be all alone. And yet, Marinette retorts saying, "We'll see".}}

Gina Dupain
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.

In "Heroes' Day", as Ladybug she sees grandmother offer her support in the Paris rebellion by telling her that everyone in Paris is on the side of the heroes.

Kagami Tsurugi
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.

During "Frozer", Marinette does harbor a little grudge against Kagami when she thought Adrien had a crush on her and secretly called her "Ice Queen" and yet she does take her advice about being less hesitant.

Luka Couffaine
Marinette and Luka first meet in "Captain Hardrock", and she quickly develops romantic feelings for him. At first, Marinette is startled by him and stutters when she speaks to him, but she warms up to him as she listens to him play the guitar. Alya notices Marinette's interest in Luka and teases her about it, although Marinette denies it. When Luka later compliments Marinette when he calls her "incredibly brave," Marinette, as Ladybug, blushes.

Plagg
Marinette officially meets Plagg in "Style Queen", quickly aware that he is Cat Noir's kwami. She doesn't want him to risk using his powers dangerously, but she appreciates his help in defeating Style Queen, and she gets relieved when he reassures her that Cat Noir will be back next time.
