A hypnotist and a bat with a clown and a jester

We're walking inside this chemical factory, I didn't notice how fucking big this place really is. This factory has many rooms for industrial work, filled with different types of machines and giant chemical containers. The only sources of light are the windows (some of them are broken) and some of the lightbulbs.

I'm scared as shit while Batman is unfazed by it. We continue walking without a clue where the Joker is until we find a staircase with an arrow painted neon green pointing at the second floor.

Batman then walks through the staircase, I follow him and once we're up he looks across a hallway and says to me "There they are." I look in front and see that at the end of this hallway a room with the door open and all the hostages tied up on the floor with bags over their heads, thankfully they're still moving a bit so they're alive.

I then gasp and follow Batman as we both run to that room.

Meanwhile, Harley Quinn is walking through another hallway on the second floor while thinking "Puddin, you always loved overcomplicating things."

She then walks towards another hallway where there's more light and says to herself "I just wanted to have a nice date with Pammy and then you threaten to release your stupid chemicals on this city once again..."

Harley then looks at the mallet that she's holding with both her hands; then with a look of frustration and regret across her face, she asks herself "Why things can never be as I want them to be?"

But then her monologue is shortly interrupted as she hears a noise at the end of the hallway. She holds her weapon with all her strength, really to fight whoever comes that way, thinking it might be the Joker.

Then she gets closer and closer; these hallways are intertwined so this person shouldn't be able to see her surprised attack. But just as she's holding her mallet up ready to smash some heads with it, she then suddenly tries to stop as she's surprised to see Batman running across the hallway to a room at the end of it.

Harley then gets distracted as she says "Bats!?" but then as Harley doesn't pay attention, she accidentally collides with someone.

"Ouch!"

"Fuck!"

While Batman managed to enter the room, he turned around and saw that I fell on the ground as I stumbled upon someone he immediately recognized.

Batman looks at us and says "Harley!?" Then while still being at the ground I ask "Wha-What the hell!?"

My body hurt from the sudden fall and I was quite confused until I saw who I collided with, an attractive blonde woman with a weird red/black outfit and white skin. I think to myself "Damn... She's hot."

But that moment was cut short as I heard the sound of a thick and heavy metal door closing the room, leaving Batman inside of the room, while me and Harley are outside. I then scream "FUCK!"

After the metal door closes, Batman looks around the room, it's a big round room with a bunch of metal pipes, chemical tanks, and white lights. On the surface level, it seems like it's only him and the scared hostages who are still tied up across the floor, but he knows that someone else is also in this big room.

He says with a reserved tone to his voice "What are you planning to do Joker?"

And as he said that, a man walks from behind one of the tanks, the Joker. This man has green hair, his skin is completely white, he wears a purple suit, green tie, purple gloves, black shoes, and disgusting red lips on his mouth as he smiles.

Joker smiles as he holds a wireless remote detonator with a red button in one of his hands. Then he says to Batman "C''mon Batsy, it's been quite a while since we last saw each other, I still have that scar that you gave me on that last fight." And Batman answers "And I'm gonna give you more than a scar if you don't explain to me what's going on."

Joker then laughs a bit and tells Batman "I'm glad to see that you're as charming as always..." Joker then walks around the room while saying "You'll see, there's a reason I haven't hurt the hostages yet; these men and women were kind enough to make a gift for me."

Batman then asks "A gift?"

Joker explains "Yes, this factory has been receiving a bunch of money from Wayne's Enterprises to upgrade all of their equipment, so I'm happy that they were kind enough to let me use their equipment to make more venom for my toys."

Batman frowns as the Joker explains what he's doing, Batman knows that the tanks of this room are filled with Joker's venom, and they probably have small explosives behind them; so if he presses that button of the remote detonator, the small explosions will make giant holes on the tanks, making the chemical flood the floor, drowning and infecting all the hostages with the venomous liquid.

Joker then has an evil grin as she knows that Batman is on the same page as he is, so he also adds "But my toys aren't the only thing that got an upgrade, Batman..." Joker places the remote control on a table behind him, I then say "I've also been playing around with some variants of my venom, one which makes me able to do this."

The Joker smiles with a creepy smile as he quickly grabs a heavy barrel filled with water and throws it at high velocity in Batman's direction. Batman dodges it, the barrel smashes against the wall making the water inside of it begin to leak. Joker must've made a variant of the venom to give him enhanced physical strength.

Batman then draws his bat hook and metal fist knuckles; meanwhile, Joker says "Did you ever dance with the devil?" while he smiles and both of them prepare to fight.

Meanwhile, I'm furiously knocking at the metal door screaming "JOKER! WHATEVER YOUR NAME IS! OPEN THE FUCKING DOOR!" Harley then tells me "I doubt he can hear you, he likes to have his moments with B-man confined so nobody interrupts them."

I then get confused and ask her "Ok, answer me honestly, Who are you? And why are you here?" Harley then smiles and answers me "Well kiddo, my name originally was Harleen Quinzel, but you can call me The Amazing and Fabulous Harley Quinn!"

I think I'll call her Harley for short.

Harley then continues "As for why I'm here... I'm gonna use this mallet to hit the Joker's head as hard as I can."

Wait a minute, I think to myself "Harley Quinn... Joker... Wasn't she like an ally of him or something like that? Well, my hypnosis makes people unable to lie, so I'm guessing they aren't on the best of terms, to say the least."

Then we both and Harley hear some crashing noises coming from inside, Harley then walks in another direction and I ask her "Hey, where are you going?" Harley then tells me "We can't enter from there dummy, plus I know how Puddin loves his escape routes, there must be another way to enter the room." After she explained that I said, "OK, I'll go with you."

After that, I begin to follow Harley and she asks me "So... Are you the new Robin?" I then answer "What? No... I'm Jas- I mean, I'm Hypnoz!" Harley then looks at me unimpressed and I just say "Let's just... Find a way inside." We then continue to run towards the back of the room, in hopes of finding a way to enter.
