Third Person POV:

Batman wakes up groaning, still disoriented by the explosion. Harley Quinn and her goons come over 

Harley: Poor Dr. Young. Still, you know how Mr. J hates a squealer. Oh...and talking about squealers. 

Batman looks up and sees that Harley has taken Warden Joseph as hostage

Harley: This one-eyed idiot thinks he runs the place. Talk about crazy! Sorry Bats, I got places to be. Take care of him, boys. If he gets up, knock him down, but not too rough. Mr. J needs him at the party.

Y/N: Ngh...

Batman gets up and gets ready to fight the goons

The first goon lunges at Batman, swinging a baseball bat, but Batman deftly sidesteps the attack, delivering a swift counterstrike that disarms the thug

Batman, using his superior combat skills and tactical awareness, takes on the remaining adversaries. He incapacitates them one by one, each move calculated and precise

He then checks on the dead body of Dr. Young

Y/N: Oracle, Dr. Young is dead. Have you figured a way past these security gates? She told me something about a production plant hidden in the Gardens.

Cowl Interface: Recalibrating cowl.

Barbara: Batman, can you hear me?

Y/N: I hear you.

Barbara: The security protocols there are a two-part biometric sequence generated by the Warden, using a code sequencer.

Y/N: And destroyed by the Joker in the safe explosion. Harley has the Warden, and he's the only chance we have to get past these gates

Barbara: Okay, good luck.

Using the forensic scanner in his cowl, Y/N tries tracking him down by finding traces of his DNA around

Walking some more, he arrives at the Green Mile, an area in the asylum where more of the most clinically insane patients of Arkham are locked up in along with Pamela Isley, aka Poison Ivy

(Played by Jessica Chastain)

Ivy: Stop! Stop! Batman...please! You've got to help my babies!

Y/N: I'm really not interested in a bunch of flowers, Ivy.

Ivy: They're in pain...crying for help!

Y/N: Just stay where you are. Last thing I need is you running free.

He then leaves Ivy and keeps searching for the Warden

When he eventually finds him, he sees that he's all tied up to a chair in a control room 

Warden Joseph: Batman...thank God. Harley locked me in here.

Y/N unties him

Y/N: I'm going to need your access card

The Warden gives his access card to Batman, who inserts it in his cryptographic sequencer, obtaining control of the security gates in the asylum

Y/N: Stay here and wait. Someone will come by and pick you up.

He looks at the security cameras and sees that Harley has freed Poison Ivy

Batman proceeds to Arkham East to deal with the growing chaos in the cell block transfer corridor. As he arrives there, he sees Harley Quinn

Harley: Surprise! Y'know, Bats, I always thought there was a spark between us.

This makes Kate talk on Batman's ear

Kate: Okay...if she throws herself on you one more time, I swear to God I'm leaving this cave and I'm sticking my foot so far up her ass, she's about to become a puppet.

Batman ignores Kate's comment and focuses on Harley Quinn, who continues her taunts

Harley: I bet I'm so more fun than that little bird girl you hang around. Catch me if you can, Bats!

Harley runs away, making Batman chase after her

He then arrives at extreme incarceration, where he sees Harley in a control room completely protected

Harley: Here he comes, Mr. J!

Joker: Wonderful. I'll leave it to you, my dear.

Harley laughs

Harley: Okay...this is your cue, Benny boy

A door opens, revealing Benjamin Pointdexter, also known as Bullseye. Once a special FBI agent, now a skilled hitman who once worked for Wilson Fisk

Y/N: Pointdexter...I thought you were at The Raft.

Bullseye: Well...Arkham is for the crazy ones. And guess what? I want to get a little crazy tonight...

Y/N: So you wanna get nuts? Okay...let's get nuts.

Batman and Bullseye engage in a fierce hand-to-hand combat. Bullseye skillfully throws his deadly knives, aiming with lethal precision, while Batman dodges and counters with his combat expertise

Amidst the clash, Harley Quinn watches with amusement, occasionally cheering on Bullseye.

Harley: Show 'em, Benny! Make Mr. J proud!

Batman strategically maneuvers around the room, utilizing cover to avoid Bullseye's lethal throws. The sharp blades embed themselves into walls and objects, narrowly missing Batman each time. The vigilante remains focused, analyzing Bullseye's patterns and movements

He contacts Oracle in order to find a weakness, a structural failure, anything that can give him the upper hand

Y/N: (whispering) Oracle, Bullseye seems stronger than usual. Can you tell me what they did to him?

Barbara: Let me check here...seems like after his fight with Daredevil and Kingpin a couple of years ago left a pretty nasty injury on his back. Fisk completely destroyed his T8 and T9 vertebrae. They replaced important parts of his spine with an unspecified metal. Looks like that enhanced his strength

Y/N: I can't fight from distance. I have to bring him up close.

He gets out of cover and tries his best to dodge Bullseye's throwing knives, getting some parts of his suit ripped and his cape punctured

As a last resort, Y/N pulls out one of his batarangs and throws one of them at Pointdexter

He throws it at his direction, but the mercenary dodges it and smirks. However, the batarang comes right back at him and sticks on his back

Y/N: Bullseye...

He presses a button on his gauntlet and it electrocutes Bullseye, making even more painful due to the fact that his new spine has metal parts

The electrocution surges through Bullseye's metallic spine, causing him to convulse with pain

Bullseye: AAAARRRGHHHH!

Harley: Poor Benny. Well...I guess I'll do this myself, then.

She gets out of the control room and cartwheels herself towards Batman and attempts to kick him, but the vigilante grabs her leg and takes her down easily

After that, Batman locks Harley up in a cell

Y/N: Get in.

Harley: You won't find Mr. J. He's in the secret lab in the Gardens and...oh shit!

Y/N: Yup, I know.

He walks away and heads to the Gardens

Y/N: Oracle, Harley has been...subdued.

Barbara: Great, but there's one more thing. I re-routed a WayneTech satellite to show thermal scans of the island. The Gardens are showing up hot. Something bad is happening there.

Y/N: Understood.

When Y/N arrives at the secret lab in the botanical gardens, he sees Joker and two of his goons there

Joker: Well, look who discovered our secret lab. Since you've made it this far, let me show you what I've cooked up

Joker grins wickedly, revealing a concealed pistol. He shoots a dart loaded with the new Titan formula into each of his goons. Their muscles grow larger, and veins pulse under their skin

The transformed goons, now under the influence of the enhanced Titan formula, charge at Batman with increased strength and aggression

Despite the increased strength of his adversaries, Batman's superior combat skills and intellect shine through. He employs a combination of martial arts, gadgets, and environmental advantages to take down the Titan-infused goons

At the end of the fight, Y/N blows up some of the Titan barrels in the lab using his explosive gel. However, Joker escaped and took a little bit of Titan with him

Y/N: Oracle, I've destroyed the Titan production facility. But Joker has escaped with enough to cause us real problems.

Barbara: Just when you think it can't get any worse.

Y/N: They've been using a Venom plant hybrid to create the Titan strain. The plant's the key, and there's only one person on Arkham Island who can help us

Barbara: And what makes you think Poison Ivy will help you?

Y/N: If her plants are in trouble, she'll listen. She's somewhere over here, in the Gardens.

He then finds Poison Ivy in the gardens, talking to her plants 

 Ivy: It's alright, my darlings. I'm here now. My poor darlings...Yes, I know he's found us. But I won't let him hurt you...I'll kill him first

Y/N: Ivy...I know Dr. Young mutated these plants to produce Venom.

Ivy: Yes, and I heard it through the grapevine that the evil woman paid the price

Y/N: I need you to help me create an antidote.

Ivy: Why should I? Let Joker have his fun. I'll enjoy watching you squirm.

One of Ivy's plants sneak up on Batman, but he grabs one of its vines and squishes it, hurting the plant and Ivy

Ivy: AAAAAAARRRGH!

Batman, still holding the damaged plant's vine, tries to reason with Poison Ivy

Y/N: You've been in the dark too long! Every plant on this island will get the same unless you cooperate

Ivy: There's a plant...growing deep in Arkham Island. Only it can counter the effects of this Titan strain.

Y/N: Where do I find it?

Ivy: Oh...Killer Croc's lair. You didn't think it would be easy, did you?

Y/N: Get back to your cell...or I'm coming after you next.

Batman, determined to retrieve the plant, starts making his way towards Killer Croc's lair in the depths of Arkham Island

In the main hallways of the asylum, he senses a familiar smell and coughs, thinking ᴎvᴎꞁɔiᎸᴎbꙅiᴎbivᴎiudvibᎸdvu
