The inventor in the lab held up a device that looked a lot like a large channel changer.

"This is the reversal ray. The beam can reverse anything about anyone: turn good to evil, virginal to slutty, male to female, strong to weak. Anything at all. The more times I hit a person with it, the more things I can reverse."

The figure glanced at two other devices on the bench.

"The perfect addition to the melding ray, which can combine any two or more people into a single person, and the splitting ray, which can split up any person to various selves. Now that they're all ready, who should my first target be?"
