Zelene

Zelene is what many would say is an alien invader. She came to this planet with the simplest of intentions.

To overthrow all other leadership and become Queen of her own world, surrounded by loving and doting subjects and living a life of luxery.

Of course, this can't be a simple as just 'zapping herself into the textbooks and rightful heir' or something. No, she's work to do to even get close to this goal.

She has plenty of advantages to get her way, of course. The easiest being her figure. A standard amongst her kind, simply to allure the more 'primitive' minds easily swayed by, in simplest terms, 'thicc girls.'
More effective, however, is her multitude of 'mind-controlling' abilities. Again, standard amongst her kind, working themselves into higher positions of power before eventually overthrowing said planet for thier own means. One might even call them a virus, to put it bluntly. Invading planet by planet, growing thier race whilst enslaving each other.
