Supergirl came and lent a hand in the last chapter and now she's here to help with the breakout to kill time. However because she's one of the most powerful characters in the DC world, to even the odds for her here, she will battle tougher enemies to make sure her adventure in Gotham is just as challenging as Batman's is. And I know just the two people she can start with which you'll see in a moment here.

Batman remained where the Batmobile was parked, waiting for Harley Quinn to wake up.

Soon, she did.

"Harleen." he said to her.

Harley looked around and learned she was back inside the vehicle.

"What . . . what happened?" she asked.

"You fainted when Lyle Bolton dropped you from the roof during our fight with him."

"Oh, that I remember. He's not here, is he?" she asked alarmingly.

"Not anymore. He was defeated and hauled away by Supergirl."

Harley's eyes went wide from hearing that name.

"Superman's sister?" she asked him.

"Cousin, to be exact. After Bolton dropped you, Supergirl flew in and saved you just after you fainted. She fought and apprehended Bolton and she's now flying him back to Arkham. She said she would return afterward and has offered her services to us in apprehending the other inmates because Metropolis is void of threats tonight." he told her.

"I was saved by a flyin' alien?" Harley asked.

"Yes."

"Wait, did you tell her that I wasn't a bad guy, girl, anymore?" she asked.

"I did. She now knows of your current alignment." he told her and Harley sighed in relief.

The jester clutched at her head despite not having any head injuries of any sort.

She then looked at her own costume and realized something. She remembered how scared the hostages were upon seeing her in her outfit. She once terrorized people while wearing it and felt that she needed to change into something else if she was going to fully distance herself from her villainous past other than dropping her "Harley Quinn" name.

She had an idea, but she decided to wait until Supergirl came back.

"Ya know, those people I tried to save were scared outta their wits of me 'cause of my reputation and my costume and I can't blame 'em. I did used to commit crimes in this outfit and I figured I could use a costume change so I don't scare any more civilians when I approach them." Harley said to Batman.

Batman knew where Harley was getting at. Her costume would bring back horrible memories to those who were once victimized by her and Joker. Were it he who frightened and victimized innocent people, he too would ditch his Batsuit for something else that said "I'm different."

"Do you have any spare suits at wherever you used to spend time in hiding?" Batman asked.

"Yeah, I had tons of clothes and different costumes at my old hangout. I wonder if they're still there? It's been a long time since I last set foot in that place. Can we make a stop there later before we go after the net baddie? Or better yet, when Supergirl returns, I could ask her to fly me to my old hideout ta get changed into somethin' else." Harley suggested. Despite what almost happened to her with Lyle Bolton, Harley did not develop acrophobia whatsoever. As long as she was up in the air with someone she trusted and was comfortable with, it was fine with her. But if it were with someone she didn't trust, that was a different story.

"Good idea." said Batman.

Minutes later, Supergirl flew back to the spot where Harley and Batman were.

"I'm back." she said and noticed Harley. "I see your new friend is awake."

"So you're the one who Batsy said saved me when I fell?" Harley asked her.

"He told you, huh?" she asked.

"Yeah." Harley answered.

"Name's Supergirl. I'm Superman's cousin." she said.

"Harleen Quinzel, nice ta meetcha!" Harley said and extended her hand out for Supergirl to shake and she did.

"Whoa, your grip is strong!" Harley said when Supergirl squeezed her hand during the handshake.

"I know. It's part of my physiology." Supergirl said.

"I like yer outfit. It looks cute on ya." Harley complimented.

"Thanks. It's to kinda distance myself from my cousin when it comes to uniforms. The 'S' is part of my heritage. It was, and still is to me, a symbol of hope where I originally came from before Metropolis." she said.

"Speaking of uniforms," Harley said and told Supergirl of her request and reason for it.

"Sure, I'll be happy to take you back to your place for a wardrobe change." she agreed after the jester told her.

"Yay!" said Harley.

But before Supergirl was about to take Harley with her, she turned to Batman.

"Will you be able to handle things on your own while Harley and I are gone?" she asked him.

"I've patrolled Gotham alone before. I can handle it. Here's a radio you may use to communicate with me." he said and handed his radio to Supergirl.

Even though she didn't need it as she had advanced hearing and could hear Batman from miles away, Supergirl accepted it anyway to humor him.

"Thanks." she said and took it.

She turned to Harley and said, "Here, hop on me."

Harley grabbed onto Supergirl's back and they both took off in the air with Harley yelling out dramatically, "High-Ho Silver, awaaaaaaay!" while Batman stayed behind and began researching his next target on his Batcomputer.

Supergirl flew above the Gotham sky with Harley Quinn sitting on her back and the latter seemed to be enjoying her flight quite fondly.

"Whee! Giddyup! Mush!" Harley cheered and tugged at Supergirl's red cape as if they were reins.

"I'm not a horse, Harley." Supergirl said, rolling her eyes at her passenger's goofy antics. She wasn't angry or annoyed.

"I know. I've always wanted to do that and you're the closest thing to a horse, minus the saddle and reins, of course." Harley said.

"So where's your hideout?" Supergirl asked.

Harley told her and Supergirl flew in that direction.

"So while we're flying, why don't you tell me about yourself." Supergirl asked.

"Gladly." Harley said and began telling the female alien hero, in short sentences, about her past and her current status with Batman and his partners, Robin and Batgirl.

"Batman told me you dumped Joker after you decided to drop crime. It's about time, too. I've heard of him and what he does. Not a pretty picture." Supergirl said.

"Yup. Oh, and alongside the crime thing, I also prefer to be called by my real name these days. I don't go by 'Harley Quinn' anymore since it used ta be my outlaw name." she said.

"Okay." said Supergirl. "How'd you come up with that name anyway?"

"I was called it long before I met Joker. My childhood peers used to mock me with that title because of its sounding similarity to the clown character, 'Harlequin'. It's not new to me. I then started using it for my then-new name after I busted Joker out of the nuthouse on my first night as a criminal. These days, I wish I never transferred to Arkham and if that hadn't happened, I would have never met Joker and I wouldn't have turned to a life of crime. But, in a way, then I would have never met Batman either. Yeah, we had our ups and downs as opposite sides of society, but after my first parole hearin' turned ta mush, I began to take a liking ta the Bat and it's how I got ta be where I am now, tourin' Gotham and huntin' down my fellow convicts with the new man of my dreams." Harley said, sighing romantically just from thinking about the Dark Knight when she said that."

"You have a crush on Batman?" Supergirl asked.

"Oh, it's more than that, girl. I'm in love with the guy. He kept an eye on me even after I screwed up my own parole night out on the town and after bringin' me a dress I paid for at a big ol' department store, I was touched by his kindness and I fell for him. Heck, I even made out with him!"

Supergirl stopped for a moment to digest this information, causing Harley to grasp onto Supergirl's back and wrap her arms around her neck and her legs around her torso tightly to avoid falling. This didn't hurt Supergirl at all.

"What?! You kissed Batman?!" she asked. She was not angry, more like surprised.

"Sure did. It was the first time I kissed him and, like I told Joker and everyone else, I don't regret it one single bit." she said.

Calming down, Supergirl resumed her flight and Harley eased up on her hold.

"Sorry about that. I was just . . . disturbed by what you said." she apologized in case her mid-stop scared the clown girl.

"Nah, it's fine. I didn't expect you to react calmly to it. Hell, anyone else would have a similar reaction if they were told I locked lips with the Bat." Harley replied.

"Point taken."

"Ya know, if I were still into crime, I'm guessing that you'd probably do ta me what ya did to that scary guard did ta me earlier." Harley guessed.

"Pretty much if it meant scaring you into surrendering." she joked.

"So, you're not nervous bein' around me? Ya know, 'cause of what I said about my past as a crook and a psycho lover to Joker?" Harley asked, wondering what the alien girl thought of her.

"Even if you were still a criminal, I still would not be afraid to be near you, when we fight, of course. I'd pound you into mush. But if you're willing to play 'hero' tonight and every other night, then I'm fine being around you, although I admit it's gonna take some time for me to get used to that idea from what I've read about you and Joker over the years." Supergirl replied.

Harley frowned at that last statement, but at the same time, she knew it was true. She was bad for so long, she was already feared throughout most of Gotham and perhaps Metropolis and other cities that were the home turf to other heroes, so being good and changing her public image and reputation was indeed going to take some time.

"Say, how old are ya anyway? You look like a teenager outta high school ta me." Harley said while playing around with Supergirl's blond hair with her fingers which the latter didn't mind.

Supergirl told her.

"Wow, you're that age and ya still go out fightin' bad guys?" Harley asked, stunned by what she was told.

"Yeah. I only do so when my cousin's busy or is unavailable for other reasons." she said.

"So if you're related ta Superman, does that mean you have all of his powers besides the flyin' thing you're doin' right now?" Harley asked.

"Yeah. I share the same powers as him along with his weaknesses." she said.

"Weaknesses?" Harley asked.

"Yes. Unfortunately, my cousin and I are vulnerable to something called 'Kryptonite', green rock materials that came from what used to be my home planet of Krypton before it . . . became extinct." she said.

"Oh, I've heard of that stuff. It weakens your kind like a fever and makes ya mortal like us humans. I heard your cousin's experienced that sort of thing with Kryptonite multiple times during his own crime fighting missions." Harley said.

"We're also vulnerable to-" she started to say until Harley shushed her quickly.

"Ahp, ahp-ahp-ahp! I don't wanna know your other weaknesses. Kryptonite, I already know, but I don't want to spoil our newfound alliance if ya reveal your secrets ta me. There may come a time where I could get caught by enemies of yours, Superman's or mine and if they interrogate me for info on ya, I might accidentally spill your weaknesses ta them and that would not be cool."

"You'd really do that?" Supergirl asked.

"Do what?" Harley asked.

"Avoid knowing my vulnerabilities to keep me safe if you were ever interrogated about me?" she asked.

"Yeah, of course. It's my way of building some trust between us and all. I read it in a life-change book at Arkham and even if ya did spill your secrets ta me, I still would keep 'em ta myself and never tell anyone. One secret of mine is that I'm fish-intolerant. It makes me sick, literally. Oh, and in case somethin' happens to me tonight or any other night, I want ya ta know that even though we just met, you're now my new BFF." said Harley, patting Supergirl's side thrice to ensure her honesty.

"Aw, thanks." Supergirl said, touched by Harley's speech and willingness to keep Supergirl's vulnerabilities undisclosed regardless of whether or not she knew of them. Unknown to the clown girl, she could hear Harley's calm heart rate, meaning she was telling the truth as one's fast heart beat and breathing indicated deception.

As Harley was about to say something else, she suddenly saw something familiar to her.

"There it is! Go there." Harley said and Supergirl flew straight toward where Harley was pointing at.

When they landed, Harley asked Supergirl to peek inside with her x-ray vision to make sure the coast was clear.

"Is this hideout of yours coated with lead?" Supergirl asked.

"Nah. It's all wood and concrete." said Harley.

Supergirl looked around with her x-ray vision and found no trace of anyone.

"It's empty. We're the only ones here." she reported.

"Good, Joker hasn't come here yet." Harley said and she pressed a button and an elevator appeared and she and Supergirl took it.

When they arrived to their destination, the two women exited the elevator and walked around.

"Everything's the same as it was when I was last here." said Harley.

"Nice place." Supergirl said.

"Thanks. Now you wait here while I go and get dressed. Feel free ta give yourself a tour or somethin'." said Harley and she walked away to a room and shut the door.

"Oh, and no x-ray vision!" Harley called out from the room.

Supergirl held in a giggle.

"I won't!" she promised.

"Okay!" Harley said and Supergirl was by herself.

She was looking around Quinn's former hideout. Despite being a villain before, she actually had some of her things from her previous life here such as her old college and university degrees aimed for psychiatry and awards she received for her work. Publicly, these were null and void because of her outlaw behavior. She wondered why she didn't throw them out if she dropped her professional life to become a henchwoman for Joker. She could have thrown them out if she wanted to, but she didn't. Maybe somewhere inside her before her rehabilitation was a piece of her sane, former self.

How could someone as successful as her fall after meeting this Joker punk? She thought.

Later, Harley returned and when Supergirl saw her, she looked different. Harley was wearing a street biker-inspired outfit. She had no jester cap on her head again and her pigtails were back. The outfit had colors similar to her clown outfit.

"So what do you think, Super-chick?" Harley asked her while standing in a "ta-da!" position.

"It's 'Supergirl' and it looks cool on you." Supergirl said.

"Thanks. Ya want a new outfit too? I got more." Harley offered.

"No thank you, I'm good as is." Supergirl politely declined.

As Harley approached her, she guessed that the Kryptonian girl had looked at her leftover med degrees and felt she had to explain them to her.

"Even though I'm no longer a doctor in the eyes of the law and my licence to practice it was revoked, I still keep my degrees and achievements as mementos of what I used to be before I met Joker and became what I am today. I may have been nuts before, but I just didn't have it in me to throw them away. They're like rare and collectible items to me and they can never be replaced if something happened to them. I'm relieved now that Joker didn't get rid of them himself."

Harley rubbed her arm as she spoke. She was beginning to grow a little upset from her memories.

"I'm not so sure it's possible, but when I'm released from Arkham again in the future, I'm hopin' to go back to what I used to do, the doctor part, I mean, not the crime thing. But I doubt that anyone would wanna hire me to talk about their problems now that they know who and what I am or was, whatever comes first. Everyone either hates or fears me except Joan Leland, a doctor who works at Arkham and is my therapist and former co-worker. But now I want to earn it back and I'm happy to work alongside the Bat in order to do it. And if I can't return to psychiatry, then I could find some other profession. I love being a hero an' all, don't get me wrong. But someday when I'm out again, I'll have to find work to make a livin' once again and crime-fightin' don't pay the bills and put food on the table, ya know." said Harley.

"Well, I'm sure you'll succeed in that when you're released. Even before you told of what happened on your first parole, I already heard what happened in the papers and how bad it was at the time. I know you can make it work again." said Supergirl.

"Thanks. Now that I have what I came for, let's go find Batsy and resume the fugitive hunt."

"'Batsy'?" Supergirl questioned while trying not to laugh at the name.

"It's what I call Batman. I have other names for him that I call him by, but only I can use them. It's kinda my thing." Harley explained.

"Fair enough." Supergirl said and she and Harley took the elevator back to the surface and once they were outside, Harley took the video radio and used it to call Batman.

"Batman!" Harley said into it.

The radio fizzled until it showed a screen of the Dark Knight himself sitting inside his car.

"Harleen, what's wrong?" he asked her.

"Nothing. I'm callin' to tell you that I got what I need and Supergirl an' I are about ta fly back ta you." said Harley.

"Okay. Supergirl, can you detect my location?" he asked.

Supergirl stepped into view of the video so Batman can see her.

"Sure. I can hear your car from here." she said.

"Good. Fly Harleen and yourself to where I am." he said.

"Got it. We're on our way." she said and the radio stopped.

"Well, grab hold of me again." said Supergirl.

"Okay." said Harley.

Supergirl crouched down to allow Harley to grab onto her and they took off into the sky again.

Batman was driving around Gotham, looking for his next target, when he heard a whooshing noise coming from above.

He knew what caused it.

He stopped the Batmobile and saw Supergirl descending to the middle of the road in front of him with Harley Quinn in tow.

"We're here." Supergirl said.

"And I went through a wardrobe change! Pretty hot, huh?" Harley said while twirling around to show her look off.

"So I see." he said.

"If street racin' was legal, we'd beatcha in a race across Gotham." Harley said.

"True. One of the things that I've heard some people say about my cousin and I are that we're both faster than a speeding bullet and more powerful than a locomotive." said Supergirl.

"Did ya find anyone left to go after?" Harley asked Batman.

Batman showed them his Batcomputer and the two girls looked at the screen.

"'Arnold Wesker, a.k.a. 'Ventriloquist'." Supergirl read aloud and read what he does.

"He commits crime with a puppet?" she asked in confusion. "Now that is crazy."

"It says here that he's causing trouble at a casino here in Gotham."

"Then let's go get him." said Harley.

As the three were about to make a move, the Batcomputer suddenly beeped.

Someone was calling.

Batman picked it up.

"Hello?" he said.

"Batman!" It was Robin.

"Robin? What is it?" Batman asked.

"We found Poison Ivy at the Gotham zoo and other than the animals she's released, she's not alone on this one!" said Robin.

"What do you mean?" Batman asked.

"She's joined forces with some blue-haired psycho who can spew out electricity like that yellow, cartoon mouse critter on tv! Batgirl and I aren't equipped to handle this other person and they're chasing us as I speak!" Robin said in a panic.

The video showed him looking around and evading a moving vine while Batgirl was seen evading a large lightning bolt that almost hit her from an unknown source.

"Yeah, you better run, ya little Bat wannabe!" yelled a voice that came from said unknown source. It sounded female.

Supergirl's eyes lit up when she saw the lightning bolts because she recognized them and knew who was capable of doing that.

"We'll be right over! Hang on!" Batman said and the computer returned to its normal status.

"Aw crap! Not her!" she said.

Batman and Harley darted their eyes at her.

"You know who Ivy's with?" Batman asked.

"Yeah. It's a woman named Leslie Willis. She's an electrokinetic metahuman who used to be a radio shock jock in Metropolis and bad-mouthed my cousin on the air every day until she was, one day, struck by lightning and gained her electrical abilities. With that, she started calling herself 'Livewire' and became an enemy of my cousin who had fought her a few times before. Despite Superman's powerful nature, Livewire was, and still is, a handful to deal with for him and since she's now teaming up with that plant lady foe of yours, it's likely that those two could be very dangerous together. As if committing crimes alone isn't dangerous enough for either one of them." Supergirl said.

"So, she's a real 'shocker', huh?" Harley asked.

"Apparently so. She was more than a match against Superman the first time and I read of a time she joined forces with someone called 'Parasite' in an effort to seek revenge against Superman, which didn't go so well for either her or that other guy."

"'Para-who'?" Harley asked her.

"Parasite, a metahuman who can steal and absorb the powers, abilities and memories of other people he touches. From what I've read of his failed team-up move with Livewire once, he was put in a comatose state after he absorbed the powers and weaknesses of both Superman and Livewire. No one's ever heard from him since." said Supergirl.

"Fightin' Red's gonna be a toughie. She's been my best friend since the day we met and if I go up against her, she's gonna see me as a Judas or Benedict Arnold or some other third thing that involves stabbin' people in the back." Harley said.

"Are you going after this Poison Ivy person?" Supergirl asked.

"We must. She's one of Arkham's fugitives who must be returned. This Livewire woman you spoke about is not from around here and has never been incarcerated in Arkham before. However, despite that, since you say she's dangerous as well, she too must be taken down." Batman said.

"Honestly, I've never actually fought Livewire before either unlike my cousin. But if he can beat her, then so can I. You two go ahead and find that Ventriloquist guy and I'll deal with Livewire and your plant friend and save your other friends from them. I was thinking of going after the tough ones during my stay while you go after the soft ones. That way, it'll make the mission easier for you two." Supergirl offered.

"Good idea. We don''t have any anti-lightning gear with us anyway." said Batman.

"Yeah, plus you're super-tough on the outside and if she zaps ya, it shouldn't hurt ya as much as it would hurt us if we were ta fight that electric chick." Harley added.

Thanks . . . I think. Now let's do this thing." Supergirl said.

Batman and Harley got inside the Batmobile and drove in one direction while Supergirl started to fly in another.

Batman and Harley Quinn are going after Ventriloquist while Supergirl has decided to go after Poison Ivy and her new partner-in-crime, Leslie "Livewire" Willis, who had just arrived to help cause trouble in Gotham, her first real battle in my fic. How will the battles between both sides turn out? One of you requested that Supergirl face tougher foes, well you are about to get your wish! Her easy victory over Lock-Up was part of her introduction, so consider that a one-time thing. The next chapter's gonna be a loooong one and I'm gonna need a lot of energy drinks to stay up writing! Kidding, but still, the next chapter's gonna take a while to do, so stay tuned.

Harley Quinn's new outfit is the one she wears in "Batman Arkham City". I liked her better that way than the nurse outfit from "Asylum" or the one she wears in "Knight" (although I admit the "Knight" outfit is kinda cool) No offense to those who liked the aforementioned outfits before and after "AC".

Robin's comment about Livewire being like an "electric mouse" is a nod to Pokemon due to it and Batman TAS both airing on the same television station, Kids WB, back in the late 90's and early 2000's. The remark was my way of making a shout out to the station that aired the two shows that made my childhood tv viewing grand. I even remember watching a joke scene where Batman and Robin have a Pokemon battle and Robin sent out a Golbat and Batman fried it with one of his weapons and Robin called him out for cheating. I saw it on Youtube and, after all these years, seeing that scene still makes me laugh to this day. I feel old as f***!"

PS: Some of the material and events in this story may be mixed and, after reading a comment one of you posted about Supergirl and Batgirl's acquaintance in the DCAU's timeline, I barely remembered that those two met way later in the show rather than early. I forgot about that, but it's already there so . . . my bad. Besides, half of the stuff in my story ain't exactly canon to the cartoon's timeline, so bear with me.
