A sweet yet clumsy girl who is an amazing fashion designer who also has a love of video games, and a boy named Adrian Agreste.  However, she is so awkward and scared of being rejected by Adrian that she acts like an absolute klutz around him.

However, along with her daily life and interests, she's also been chosen as one of the protectors of Paris when she was given a special jewel called a Miraculous which contained the kwami known as Tikki who acts as both Marinette's guide, confidant, and power source.  When Marinette tells Tikki "Spots On!" she becomes the super hero known as Ladybug.  Together with her partner, Cat Noir who is secretly her love interest, Adrian, she protects Paris against Hawk Moth/Shadow Moth/Monarch who unknown to them is Adrian's own father, Gabriel Agreste.
