There is no Batman in Gotham City comics.

Wayne Manor, overgrown with weeds; the primitive and desolate Bat Cave.
When Bruce fell in Crime Alley with his parents, Gotham did not get any worse for the next twenty years.
But it doesn't seem to be much better.
When the Joker wiped off his pale makeup, the young penguin was still biding his time, and Harvey was still racking his brains to take down Maroney's gang.
The whole world is so real it's terrifying.
Perhaps it's missing a spoonful of the base liquor called "Extreme Villain"
Perhaps it lacks the embellishment of supernatural abilities and mutants.
But this doesn't affect the fierce taste of this "Bloody Mary".
Drink it, drink it all in one gulp!
Then, amidst intense dizziness, witness the birth of a "heretic" Batman.
