A/N: This takes place in the Arkham Smash continuity from Batman: Arkaham Smash 1 and 2.
-Rooftops of Gotham-
On a cold night, Hulk sits atop a tall rooftop and looks down over the city, sighing to himself as he leaps down into an alley and walks along a sidewalk as he occasionally stops minor crimes, such as a purse snatcher and a man holding a woman at gunpoint in a different alley. He then quickly leaps up to a rooftop, noticing in the distance...a feminine figure jumping across rooftops with rather impressive agility until the jumps to the edge of another building, which crumbles beneath her feet. She hollers in shock as she begins to fall, but Hulk lands on the rooftop and catches the woman and pulls her up. As he pulls her to safety, she looks at Hulk and breathes heavily, glad that she didn't plummet to her death. "You alright?" Hulk asks.
"I am now...thanks to you." Catwoman says as she admires her rescuer's physique. "I'm Catwoman. Who are you?"
"Hulk." He says simply as he looks at her, smiling lightly.
"Hulk. Nice name. Makes you sound so...brutish." Catwoman says lowly, yet sensually.
"Watch it." Hulk says. He didn't like to be called anything that was similar to 'monster'.
"Hehe. I get the feeling we're gonna get along. Now if you'll excuse me...I have somewhere else to be." Catwoman says as she turns around, only for Hulk to make her look at him. He didn't show it, but he wanted to talk to her more.
"What's the rush?" He asks with a light smile.
"Hmm...none, now that you mention it." Catwoman says as she sits next to Hulk on a much more stable part of the rooftop, looking down at the city streets with him. "You know...once you get past the muscles and green skin...you actually look very handsome." She says seductively.
Hulk chuckles and looks away in embarrassment. "T-Thanks."
-The Next Day-
Hulk leaps across rooftops before landing in an alley and stopping another crime with minimal effort, though he leaves the criminal alive, startling several passerby's as he made the ground shake when he landed, leaving a crater in his wake. "Really have to nail my landings..." He mumbles to himself as he wanders into a grocery store. Good thing he has stretchy pants, as one of his pockets has emergency cash in it.
-Grocery Store-
Hulk enters the large store, getting a large collective of gasps from the patrons, who weren't expecting Hulk of all people to walk in. He enters several aisles, grabbing milk, juice, and various fruit and junk food. He had large hands, so he didn't need a cart to carry the items to a register. After being told the price of all the items, he grumbles and pays up before walking out, unaware that Selina Kyle was watching him the entire time.
"Hmm...interesting..." Selina says to herself as she slowly struts behind Hulk, following him outside.
-Wayne Manor-
Hulk leaps back to Wayne Manor, landing on the front yard before entering the large mansion and going into his room, putting the supplies he bought on his dresser, except for the milk, which he stores in an industrial refrigerator, courtesy of Lucius Fox. Outside Wayne Manor, Selina, now in her Catwoman outfit, hops up to the second floor window, peering into Hulk's room. She smiles as she spies on Hulk, who is now watching TV, unaware that she's spying on him.
"Why are you living here, of all places...?" Catwoman quietly asks herself as she keeps watching Hulk, who lays down, turns off his TV, and goes to sleep. Catwoman smiles as she uses her clawed glove to unlock the window. She then quietly lifts the window and enters the bedroom, looming over Hulk as he slumbers. "Who knew monsters could be so...annoyingly handsome...?" She asks herself in her mind as she takes off her glove and gently rubs her palm along Hulk's face. Lucky for her, Hulk was slumbering like a literal giant, so he didn't even know what she was doing, let alone that she was even in his bedroom to begin with.
-The Next Day-
Strip Club
A crime lord and his goons enter a strip club and sit in front of the stage and watch a girl dance. A few minutes later, the girl leaves and heads backstage to get some rest. Much to the crime lord's surprise, the next girl to show up is none other than Catwoman, who smiles mischievously as she struts across the stage and starts to dance, her moves stunning everyone; she was really good at making men desire her.
"Ohhh...You naughty kitty." The crime lord says as Catwoman slowly unzips her outfit enough to show her round breasts, making all the men whistle in arousal. She then smirks as she turns around. The crime lord smiles as he spanks her ass.
"Mmm...ow." Catwoman moans.
"You know what I'd like to do to you?" The crime lord asks as Catwoman walks off the stage and starts grinding against him, much to the annoyance of the other men there.
"Mmm...I can only imagine." Catwoman says lowly.
-Backstage-
Catwoman and the crime lord head backstage. Once she's sure that they're alone, she pulls her whip out and lashes it around his neck. "You're finished smuggling drugs. A friend of mine almost died because of you!"
"Aww, and I thought I'd have the pleasure of screwing your brains out..." The crime lord groans.
"I don't sleep with criminals. They're not my type." Catwoman remarks as the crime lord yanks Catwoman towards him and grabs her.
"Really? What about that monster that's been running around? You sleep with him yet?" He asks, unaware that Hulk himself was in an alley just outside the strip club, able to hear everything that he was saying. He growls as he kicks the door open, startling the two. "I-It's you!" The crime lord stutters fearfully.
"Let her go...or you'll get smashed!" Hulk growls as he clenches his fists. The crime lord pushes Catwoman to the side and pulls out a gold-plated handgun and unloads it on Hulk, who stands perfectly still as the bullets harmlessly bounce off of him, crumpling up like paper balls. "That was dumb. Very dumb."
"So you're bulletproof. Good to know." Catwoman remarks as Hulk walks up to the crime lord and lightly tosses him into a wall, leaving a crack in it. Thanks to Batman training him over the years, he was able to use his powers on criminals without killing them. "Thanks, But I had him on the ropes..." She says confidently.
"Ha! Sure you did." Hulk mockingly says as he looks at the sexy femme fatale. "That's twice now."
"What?" Catwoman asks.
"I've had to save you twice now, Cat. Better not make it a habit." Hulk remarks with a grin as he walks out with Catwoman.
"Hehe. I'll keep that in mind. Thanks...for saving me. Again." She says with a smile.
"No problem." Hulk says. "Be careful next time, kitty cat." After talking some more, the two say their goodbyes as Catwoman watches him leap away back to Wayne Manor.
"Good thing I know where you live..." She says lowly, with Hulk being too high up to hear her.
