Makima

On the surface, she seems to be a kind, gentle, social and friendly woman who is almost seen wearing a smile on her face the entire time and acts relaxed and confident even during a crisis, speaking in a professional tone to her workers. Her true face is of someone that is Machiavellian and calculating, who sees people around her as nothing more than "dogs" she can use as much as she likes and must obey her without any hesitation.
