Miraculous: Les aventures de Ladybug et Chat Noir

Set in modern-day Paris, the series focuses on teenager Marinette Dupain-Cheng and her classmate and crush Adrien Agreste. When evil arises, Marinette transforms into her secret superhero persona Ladybug, while Adrien transforms into his superhero persona Cat Noir, using powerful objects known as the Miraculous. Oblivious to each other's true identities, the two work together to protect Paris from the mysterious villain Hawk Moth, who covets and attempts to steal their powers by using his akuma, butterflies infused with black energy, to influence and transform everyday citizens into supervillains.
The concept for the show originally dealt with political themes, geared towards teens and young adults. However, after failing to gain traction with networks, it was retooled for a younger target audience. (source: en.wikipedia.org)
