This is my first Captain Boomerang Fanfic. I've never read the comics, but I've read a lot of Batman/know a thing or two about the universe. This Captain Boomerang is based on the Suicide Squad movie and this is my take on Captain Boomerang, which is why he might vary from the actual comics.

This is the first part of a series, which I suspect will be pretty long.
Please note that English is not my first language, which is why there might be some mistakes/grammar mistakes.

Last but not least: enjoy, I've worked really hard on this.

To say the pub was packed would be an understatement. There were people everyone, mashed together in the bar, at the tables and in the corner. A typical Christmas Eve in Gotham which, much like New York, were city that never slept.

To a thief a packed club filled with people was the same as being locked in a candy store at night was to a kid: easy access and free picking. And that was something that Missy had full intention of using to her advantaged. Missy, which wasn't her real name, but it was the name she went by right now, had been struggling to make rent for weeks. She lived in an old building not far from here, and if it hadn't been for her landlord she would had been kicked to the curb weeks ago. But the old man had a soft spot for her. Maybe it was because she always had this haunted look in those extremely blue eyes of hers, or maybe it was because he felt pity for her. Maybe he would make her pay back by sleeping with her.

Missy didn't know, and she didn't care: he could feel sorry for her all that he wanted, he could even care about her, or he could hope she would strip down and get on his knees for him. She didn't give a shit about him, or about any other, and as long as it worked in her favor he could think what he wanted. In fact Missy wasn't the kind of person who gave a shit about anything at all. She lived to survive, and that was it. Sure she liked music, good food and good booze, but when it all came down to whether she lived or died she could live without music, eat from the garbage and don't drink anything but the cheapest beer. Anything to stay alive.

She had spent Christmas Eve pickpocketing every person she could in the bar, so when midnight came she decided to leave for the night. The pockets of her leatherjacket – which were at least two sizes too big – were heavy with wallets as she walked towards the exit. Just before she reached the exit she noticed someone stepping into the pub. A man, big as a fucking tower and build like a brick wall. He was wearing a long jacket, which was open and allowed her to get a glimpse of a dark blue shirt. On top of his curly hair he wore a hat, but that wasn't what caught her attention: it was the gold chains around his neck. A guy who could spring gold like that had to have some kind of money. She didn't even have to think twice before she let her hand slip into the pocket of his jacket as she passed him by the exit to get a hold of a wallet. She didn't look at him, knowing fully that could give her away, but instead continued out the door and out into the street, very pleased with tonight's harvest.

She had to leave the crowded street and go through a couple of alley's to get back to her apartment. Any other girl might have tried to find another way home, a longer one with more streetlight and more people, but Missy didn't think twice when she turned down the first alley, hands in her pocket and her head hidden under a hood. Her footstep was light and she had reached about half way down the alley when a voice caught her attention. "Though ya could steal from me, eh?" She spun around, only to see the last guy she had stolen from at the pub blocking her path. "See, I don' lik' it when other people steal from me, especially not a little Sheila lik' ya'self." She didn't answer, unsure who Sheila was, and also not idiotic enough to admit she had stolen from him. "I wan' me wallet back!" His voice suddenly grew dark, almost a growl, as he stepped towards her with a warning glimpse in his eyes.

"I don't – I don't know what you're talking about." Her voice was hoarse, like she hadn't used it for days, but to be fair Missy couldn't remember the last time she had talked to anyone.

She didn't have time to react before he had grabbed her by the arm and almost flung her towards the wall of the alley. "Me wallet, doll."

Missy didn't think twice before she delivered a hard kick right between his legs. The sound that left the big man when her foot met his tender part was enough the make her smile, although the smile didn't last long as he tumbled towards the ground, pulling her with him in the process. "LET GO!" He didn't reply, too caught up in the pain from her kick, but weakened enough for her to rip herself from his grip and run as fast as she could down the alley where she came from, and into the street where she bumped into a man. "Woaw easy there, girl."
"There was a man… in the alley… he grabbed me…" She was painting from the run, cardio wasn't really her thing, but her words were clear enough for the man to look into the alley.
"Are you okay?" He asked.
"Ye- yes, thank you."
"Do you want me to follow you home? I'm a policeman." To show that he really was a policeman, and not just a guy trying to get a shag, he pulled a police badge from his pocket. Missy wasn't slow to nod. The man she had kicked would probably try to grab her again, and even though he was in his right to be mad at her – she had stolen his wallet after all – she didn't had some deep desire to get passed up in an dark alley again. "Yes please." She said feign to be that scared little girl the policeman thought he was protecting. Men, they were so easy to work: you just had to pretend you were some fragile princess waiting for a prince to come save her. Admittedly it was luck that had made her bump into a policeman right here, but sometimes Faith even smiled down on the miserable.

The policeman must have mistook her smile as a friendly one, returning her one himself as they walked down the street. This night had proven to be quite a ride.

...

She didn't notice the bed giving in to the extra weight, too lost in sleep. Missy had always been a heavy sleeper. After all, sleep was the only way to escape reality, and god knew she had needed to escape from time to time.

But even in her sleep she felt the cold blade pressed against her throat followed by words whispered in her ear. "Me wallet, Doll, I want it back!" She opened her eyes. The man from the alley was towering over her, a leg on either side of her as she lay in bed. "Didn't think I'woul' fin'ya' did ye." He was way to cooky and even sent her a smile as he pressed the cold blade of his knife a little harder against her throat. This time Missy didn't scream, instead she sent him flying from the bed and straight into the wall. One second he was bent over her, the next he was swung directly to the wall, which he hit with a loud thud before he fell to the ground.

He hadn't exactly expected an attack from her, and as he once again got on his feet and looked at the bed he found her sitting at the headboard, hunched together. Her eyes, which he had noticed earlier was an extreme shade of blue, was literally electrified and something looking like silver blue mist was floating around her hands in an almost pulsing way. Baffled he just stared at the meta-human in front of him for a long time before he finally acted, pulling a boomerang from one of the many pocket in his long jacket. "Listen Doll, I don' wanna hurt ya, I just want me wallet back." She didn't answer, but the pulsing mist moved faster as the bed she was sitting on started to trembled. "Okay okay here see, putting this down," he dropped the boomerang as he spoke, which made the trembling stop. "Now just.. tak' it easy." She didn't say anything, but the mist started to move slower again. "What's ya name hm? I'm Digger or George, whatever floats ye boat, doll." He didn't think she would answer him, but to his surprise she started to sit up straight, mistrust still clear in her eyes, but at least the mist vanished from hands and her eyes were once again normal, although, Digger suspected nothing was normal with this girl, who had sent him flying through the air without touching him.
"Missy." He noticed the hoarseness of her voice, but didn't point it out. There was a time to be an asshole, and now wasn't one.

"Missy, that's fuckin' ugly." Okay maybe every time was the right time to be an asshole. "Missy I kno' ya took me wallet earlier, I felt ya steal it, an' I need it back."
"Why?"

"Doesn't matter why, bu' I need it back." She hesitated, biting her lip in a nervous manner.
"I… I don't have it."
"You don – You don't have me wallet?!" He had raised his voice, which once again made the bed tremble. Fuck, this was not good. " . ?"

"I threw it out." He stared at her for a long time.
"Ya threw it out? Ya threw me wallet out?! W'at about the ring in the wallet." This time it was her turn to be surprised. She actually had actually been tempted to keep the ring, but had ended up selling it to pay the rent, which he probably wouldn't be all too happy to hear. He didn't strike her as the kind of person that liked when people stole from him. The sheer fact that he had tracked her down all the way to her apartment was proving of that.

"I sold it." The empty stare he sent her almost made her snicker, but she managed to hold it in.

"To whom?"
"A pawnshop not far from here." He looked at her for a long time, then he bend down to pick up the boomerang he had threaten her with, pointing it at her.

"Get dressed!"
"…what?"
"Get dressed!" He repated. "Ye're gonna tak' me to the pawnshop and get me ring back."

Normally Missy would never had agree to go with this digger to a pawnshop in the middle of the night, but he had threaten her a good deal what would happen if she didn't do it, and even though she would probably be able to take him out if he actually tried throwing the boomerangs at her she didn't dare. Every time she used her abilities she risked being found by them, so she rather be dragged along to a closed pawnshop in the middle of the night by a man wielding a child's toy, than she would risk being found.

"It is dis one?" He had a funny accent, Australian maybe, which had made some of his threats back in her apartment almost incomprehensible.

"Yes." She nooded. "But it's closed."

"Dat won't be a problem." He bent down to look at the locked door before finding pulling out a lock picking kit from the jacket. A couple of seconds later the silence of the night was broken by the faint sound of a lock sliding away. "There, inside!" He forcefully shoved her into the store, closing the door behind him. "W'ere's the jewelry." She didn't answer but pointed to the end of the shop where a glass showcase displayed all kind of jewelry. "Oh come to Daddy!" Missy could swear she heard joy in his voice as he rushed to the showcase and tried to open it. It was, not surprisingly, locked, and Missy had expected him to lock pick it, which was why the sudden shatter of glass being broken when he swung one of his bomberangs at it made her flinch.

"Can we go now?" She asked as he took the ring, smiling like a fool.

"Yeah yeah, in a minute" Apparently he had decided to take advantage of the broken showcase and steal the rest of the jewelry as well. She really didn't like it, but wasn't sure why she felt something was wrong, she just knew that something was off with this whole thing. Why hadn't the owner of the pawnshop been down to checked the sound of the broken glass? He lived right over the shop, which she knew because she usually only sold to him (he always gave her a good price on the stuff she stole), and she knew he had more than one gun hidden in the shop, but still he didn't come to check on the sound.
"Why is that ring so important anyway?" It wasn't really her business, she wasn't even sure why she bothered to ask, but to her surprise he actually looked at her for a second before a shrug left his broad shoulders.
"'Cus I stole it from someon' who didn't lik' to get robbed, an' now they really want it back."

"Who – who did you steal it from?"
Another moment of silence passed between them before he finally sent her a smug grin. "I stole it from Carmine Falcone."
"WHAT?" This time it was him who shushed her. "Are you insane?! You stole from one of the biggest mob bosses in Gotham?!"
"Well yeah, someon' bet me I couldn't do it, so of course I had to prove them wrong." He grinned, which made her roll her eyes and mutter something that sounded a lot like "fucking idiot". "But now he wants it back. Been hunting me for a week, an' I kinda decided to get the hell out of Gotham, but then ya came along an' stole it." Missy was beginning to suspect what kind of guy this Digger guy was. If he could steal from Carmine Falcone, and get away alive for a week, he had to have some kind of skills. Besides Incomprehensible stupidity for trying something like that in the first place.

"Well you got the ring, so can I leave now?" She asked, feeling a wave of relief filling her as he nodded.

"Yeah go ahead, doll." She turned around to flee the store but froze when a couple of gigantic dudes stepped out from behind one of the bookshelves filled with pawnshop crap.
"George Digger Harkness," one of the men spoke. His voice was a low growl, but it did manage to capture Diggers attention as Missy stepped backwards to get away from the gigantic men, and the even bigger guns they were holding in their hands. "Alias: Captain Boomerang. Wow you're almost looks as stupid as you have to be to steal from the boss." Missy felt her heard sink in her stomach. Great Falcone's men ad manage to track down the ring – and the guy who had stolen it.

Much to her surprise Digger didn't do anything but send the big guy a grin. "Nah ye don't hav' to be stupid to do that, stupid would be stealing from Batman. This was so easy it was almost lik' stealin' candy from a baby." Apparently the guys didn't like hearing that as they loaded their guns and pointing them towards Digger and Missy, who really had chosen the wrong night to get out of bed. "Ya boss should probably hire someon' better at tracking people than you. I mean, it's taken ya almost a week to find me, an' I didn't even hide me tracks that good." Digger continued, which once again made Missy question whether or not he really was retarded.

"Well we found you, and now you're gonna die. Her too." The big guy said, which made Missy take another step back, almost stepping on Diggers food, which made him push her slightly away from him.
"What? Why do I have to die because he stole from Falcone?" Missy asked in an almost childish fashion.
"Well you're here, aren't you?" The other gigantic dude answered. Digger didn't say anything, he just stood there grinning like an idiot as the bookshelves next to Falcone's men started to slightly tremble, causing some of the glass to fall to the ground and shatter. "What the-" the guy didn't get a chance to finish before one of Diggers boomerangs came soaring through the air, slicing his throat before it returned to Captain Boomerangs hand. Missy didn't scream when Falcone's guy started to gurgle as the blood feel from his throat. She just docked, as Falcon's other guy pointed his gun at Digger and pulled the trigger. Not that he hid anything since Digger had followed Missy's example and found cover by the ground. The sound of the gun being fired drown as every shelve in the pawnshop came crashing down just as the big windows pointing to the street shattered with an ear-piercing sound. Missy knew she had to get it under control, but she couldn't, and as she lay on the floor with her hands covering her head and one of Falcone's guy shrieking as he was thrown out of the missing window she could feel every control over her abilities disappear and she knew, that she would fully lose control in a matter of seconds. Last time she had done that she had demolished an entire building, a convince store with people shopping inside getting crushed by the rubble as the building had suddenly come down.

Diggers hand around her wrist was so much of a surprise she nearly screamed, and when she looked up from the floor he was grinning down to her. "Pretty neat trick" He said, ignoring the floating items from the pawnshop which was spiraling in the middle of the store like a tornado of used computers, stolen cellphones, old guitars and baby cloth. "Let's go dollface." She didn't protest when he pulled her with him, running towards the backdoor while glass was shattering behind them. "Can ya turn that shit off?"
"I don't know how!" She yelled over the sound of glass being shattered. He just grinned and said something like "-make this a walk in t'e park." Before he pulled her out of the backdoor and continued running down the street.
"Where are we going?" He didn't answer but stopped in front of a black Mercedes parked in the street. He fumbled with something for a couple of minutes before opening the door, reaching over to the passenger's side to open the door.

"Get in, we're going shoppin'." He grinned referring to a movie Missy would never had guessed a guy like him had watched. She obeyed him nonetheless, knowing full well that her cover had been blown and that she had to leave Gotham tonight. She wasn't slow to buckle up as he reached under the steering wheel and forcefully tore a handful of wires out before he used them to hotwire the car. She was more than grateful for having buckled up when he started the car and hit the gas, making the car jump to live and drive down the street with at least double the legal speed. "Listen doll, I'm not good at playing with others, but for now it looks like we're stuck together." She didn't answer, but merely gripped her seat for her life as he ran a red light, took a sharp left and continued out towards the highway. "So if we're gonna spent tim together t'ere's a few ground rules we need to make clear: firstly I won't hisitate with leaving ya somewher' if I feel like ya slowin' me down. Second: Ye won't send me flyin' into the wall again and third: I get to keep what we steal. In return I won't kill ye."

"Yeah well, I don't wanna run away with you." Missy hissed as they passed an ambulance with the lights on. Digger just shrugged.

"Ya sent one of Falcone's men flyin' through the window, I think it's safe ot say they'll be hunting ye as well, might as well work together." Missy didn't reply. He was right; it was much easier taking care of the problem when you had an ally. She just wasn't sure she wanted to have him as an ally. Especially not as he pulled a beer from somewhere in his jacket and opened it to drink half of it in one go. She knew she didn't have a choice; if she wanted to survive she would have to stick with him for a while. Whether she liked it or not.
