Different

Marinette gets akumatized but no one knows until all hell breaks loose.
Her pink and cheerful style goes to black and badass. She blocks out all her friends when they try and get close with her but none of them back away for good.

Ladybug of course disappears in this mess and Paris, especially Chat Noir, need her back to help fight the new villian. But what they don't know is that Ladybug IS the villian.

I DO NOT OWN THE MIRACULOUS CHARACTERS!!
