Every superhero has a destined supervillain.
They grow alongside each other, helping one another mature.
Superman and Luthor, Batman and the Joker, Iron Man and Hydra.
They give rise to one another, coexist, and are indispensable.
But there is one world where
there are heroes and no villains.
According to the law of conservation of matter, some heroes are going to turn evil.
As everyone knows,
when heroes turn evil, the whole world is doomed.
To save its own life, the world takes matters into its own hands and goes undercover.
As everyone knows,
there's always something strange going on between superheroes and supervillains.
The world's first day in disguise: I'm not pure anymore...
The world's one hundred and first day in disguise: Let's just destroy everything.
The little villains the world personally raised eventually grow into a force to be reckoned with.
The world: I want to retire after a job well done.
Superhero: Nemesis, something's wrong with you. I'm coming to save you.
The world: My fake-death plan keeps getting foiled. Damn that justice.
