The four rules of freelance villainy are as follows:
Always wear a mask
Never hurt civilians
Never kill the heroes you’re paid to fight.
And the bad guy always loses.
As a villain for hire, I followed those rules, facing down
heroes in scripted fights to make them look good for
the press and brand deals. Sure, losing every time was
a pain, but the money was good. Well, decent. And it
kept real heroes off my back. Well, usually.
But then I got called in to train a new villainess in the
fine art of menace, and suddenly I'm dealing with
rogue heroes, horny scientists, yandere psychics, and
in the crosshairs of one of the biggest bad guys the
world has ever known. It's a good thing I'm a villain,
because it's time to start breaking some rules....
