Marinette Dupain-Cheng and Adrien Agreste are just two high-IQed kids who come into contact with Kwamis, powerful beings. Now using their own technology, they become Ladybug and Cat Noir.
Marinette Dupain-Cheng is a girl who worked in a bakery with her parents. She had dreams of becoming a fashion designer. But there's something else she desperately wants: Freedom, the ability to be herself. Her chance comes around when she meets Tikki, the Kwami of Creation, she becomes the Miraculous Ladybug and is able to let out a side of herself she never knew she had.
Adrien Agreste is a young Model at age 14. Ever since his mother, Emily Agreste, mysteriously passed away, his father, Gabriel Agreste, has become distant to him. It's to the point where he's not even a father to him anymore. He's always had dreams of where he could be given the responsibility to become something important, something far greater than just a Model. His chance finally comes into place once he becomes Holder of the Cat Miraculous, becoming the Accumulated Cat Noir.
However, they're not seen completely as heroes, they're only seen as "vigilantes". Despite the hardships they go through, they still do their very best to protect the city from the mysterious Hawk Moth.
Season 4 of The Virus Within
Trinity is familiar with zombies, being one herself, but when strange zombies start appearing, she realizes that the world she knew might be changing yet again.
When a dangerous set of scientific notes are discovered, Trinity and her friends don't realize anything is wrong until a frantic radio call comes in. Unaware of the notes, they race to the south and struggle to determine where the strange zombies came from. The zombies are unlike any ranks previously seen, and they aren't as predictable. Some have new tricks hidden up sleeves, forcing any Stronghold they encounter to quickly adapt to the new challenge or risk being overrun. Secrets never remain hidden, and zombie apocalypses never make life easy.
