Miraculous Ladybug

Marinette Dupain-Cheng a.k.a. Ladybug (voiced by Cristina Vee in the English version and Anouck Hautbois in the French version) is a blue-haired budding fashion designer at Collège Françoise-Dupont and her family operates a renowned bakery. Marinette is sweet, joyful and a bit awkward, but respected by her peers and is very intelligent despite her occasion ditsy ways. She has a huge crush on Adrien, to whom she can barely speak to out of nervousness; her best friend Alya often tries to help Marinette to declare her love to him, only for it to end in failure. Chosen by Fu as the keeper of the Ladybug Miraculous, she can transform into the superheroine "Ladybug" with the help of her kwami Tikki, to defend Paris from Hawk Moth's villains with her crime-fighting partner Cat Noir. As Ladybug, aware of the nature of the situations she faces, she's more serious and she brushes off Cat Noir's advances on her, unaware that Cat Noir's alter-ego is the object of her own affections. Her crime-fighting tool is a yo-yo. With it, she can use her special power Lucky Charm, that can create an object, most of the time to be used with other key objects, to defeat the villains, and capture and purify the akuma butterflies, after which she has the created object turn into energy that removes the harm the villains caused [3] Her transformation call is "Tikki, Spots On!" (French: Tikki, transforme-moi!, "Tikki, transform me!"). After she and Cat Noir defeat a villain, they give each other a fist-bump and say "Pound it" (French: Bien joué!, "Well played!").
