Kara's scream could be heard echoing all throughout the DEO. Alex heard it first and felt her blood run cold immediately. Without even thinking, she flew down the halls and towards the source of the scream. Her gun was locked and loaded and she was already prepared to do whatever it took to keep Kara safe. Even if it came at the cost of her own life, Alex was ready! She finally reached the room where the scream had come from. She didn't hesitate to kick the door in and burst in. There was a snarl on her face as she pointed her gun straight ahead, but that snarl faded the moment she realized that she was pointing her gun at...

Puppies? Alex blinked, and lowered her gun slightly. Then she blinked again. Nope. Her eyes were not deceiving her. Puppies. That was what was in the room with Kara. An entire mob of furry little puppies. And Kara was right in the middle of it all. The lower half of her body was swarmed by fur and the upper half was laughing almost like a maniac. What the heck?! Alex blinked again. Then she lowered her gun the rest of the way down before taking a few tentative steps forward.

"Kara?" she asked softly.

"Alex!" Kara's eyes shot open at once, full of mirth and delight and pure joy. She looked like all of her birthdays and Christmas had come true all at once. She managed to free a hand to wave at her sister.

"Look! Puppies!" she cried, and she continued to laugh hysterically as the little furballs continued to run back and forth over her lap.

"I see that," Alex holstered her gun again as she came even closer to Kara. A few of the puppies jumped away from Kara and began to swarm Alex, yelping, barking, whimpering and whining with excitement, sniffing and nipping at the edges of her pants eagerly.

"Ah! Jeez!" Alex jumped forward when she felt something warm and wet suddenly running down her ankle.

"Hey! Careful!" Kara warned as Alex stumbled forward. "Don't hurt them!"

"I wasn't!" Alex protested, trying to regain her balance. Then she finally got a better look at the puppy that Kara was rubbing against her face.

"Is... that...Superman's cape?" she asked, pointing at the puppy and blinking in surprise again. Sure enough, tied around the puppy's neck, there was a tiny scrap of blue cloth. On that cloth was the famous red and yellow symbol, the crest of the House of El.

"Yes it is! Isn't he just the cutest!" Kara squealed, still rubbing the puppy against her face. In the back of Alex's mind, she realized that Kara's scream had not been one of pain or fear, but of sheer delight.

"And may I ask where you got all these puppies?" Alex was speaking slowly, still trying to absorb everything she was seeing. In the background, a puppy dressed up in an Aquaman suit was busily marking its territory on the leg of a nearby chair. On another leg of that chair was a puppy dressed up like the Flash, humping the leg at an impossibly fast pace. Alex looked away from the scene, blushing, and feeling bad for the poor chair in question. A few feet away, there was a puppy dressed up like a Green Lantern, rolling on its back and yipping happily.

"Oh, it's the Justice League," Kara replied nonchalantly, still snuggling the Superman puppy.

"I see that," Alex repeated. Yup. Sure enough, there were also puppies dressed up as Wonder Woman, Cyborg, Batwoman, Batman and the Green Arrow. The gang was all there, and as were the crappy capes and costumes they wore.

"But that still doesn't explain where-" Alex began.

"Oh, no, I meant it literally. These guys are the Justice League," Kara interrupted, still nonchalant. Alex's face went blank.

"What?" she demanded, almost angry, and Kara looked up at her, holding the Superman puppy out to her.

"It's Kal-El! Isn't he just the cutest!" she cried. Alex could only exhale slowly as Kara brought the Superman puppy back to her face.

"Who's a good boy, Kal? Yes! Yes you are! That's right! Yes you are!" she crooned. The puppy in question licked her face happily and she began to laugh again. In the background, the Batman and Cyborg puppies had started a game of tug-of-war using a fraying piece of carpet.

"God, my job can be really weird sometimes!" Alex muttered to herself, pinching the bridge of her nose. All the while, Kara continued to laugh as the puppies continued to swarm all over her, yipping at and licking her with fervor and playfulness.

"I could stay here all day!" Kara laughed, and she was 100% serious. It was like watching one big puppy getting distracted by several, smaller ones.

Half an hour later, Alex finally managed to get a story out of Kara. It wasn't a terribly long story, but because Kara kept getting distracted by the puppies, it had taken a bit of time to get the full tale out of her. Apparently, someone at the DEO had wanted to test out a new machine that was supposed to allow humans to turn into any animal they wanted. The goal in mind was to grant all of the Justice League shapeshifting powers on top of what they all already possessed. Unfortunately, although the machine did manage to turn the heroes into animals, those animals had not been what the scientist had expected and, at the moment, there appeared to be no way to reverse the effects of the machine. He had been trying to turn them all into wolves, or war dogs, but instead they had come out as cute little puppies, with the IQs to match...

Although there was still a bit of human personality left in each of the pups, a large portion of their normal human intelligence had vanished. That explained why the Batman and Green Arrow puppies were acting just as chipper as all the others, instead of sitting off to the side and growling, or just burying their heads in their paws. It also explained why none of them seemed too concerned with what had happened to them. They literally had no idea that anything was wrong. And as for Kara?

"Well, I was supposed to go with them," she admitted. "But something came up at CatCo, so I had to take care of that first and, by the time I got back, this is what I found," she said. The Green Arrow puppy was sitting on her left leg while the Wonder Woman puppy was walking over her right leg. The Flash puppy was now humping a stool in the back of the room and there was a sizable puddle beneath the chair the Aquaman puppy was at. Alex wrinkled her nose. The Superman and Batman puppies were climbing over each other in attempt to get Kara's attention and Kara was laughing again. Alex was sure she would pass out soon from lack of oxygen.

"Ah! Don't eat my heel!" Kara laughed as she noticed one of the Green Lantern puppies nibbling at her shoe.

"Great," Alex muttered. "Just great!"

"I know, right?!" Kara squealed. She snuggled the Wonder Woman puppy close and received a shower of face-licks in return.

Alex pinched the bridge of her nose again. Honestly! Kara was just as bad as these puppies! Had it been any of the other Justice League members who remained human, they might have tried calling for help. But no, it just had to be the one hero who was pretty much already a puppy herself! Insetad of calling for help, she'd instead decided to snuggle right up to her furry friends and play. She seemed just as unbothered by this strange transformation as the puppies did! Not that this surprised Alex. Kara really was just like them and, doubtless, to her, it was puppy paradise!

"D'awwwww! Who's a good puppy?! Who's a good puppy?! Who's a good puppy?!" Kara continued to squeal.

"I'm calling for help," Alex deadpanned. Then she walked right out of the room without another look back.

Another half hour later, Alex had managed to enlist J'onn, Winn, James and the scientist responsible to come and help.

"Sorry, ma'am," the scientist cowered under Alex's fearsome stare. "I thought I had everything right!"

"Well obviously, you didn't!" she snapped.

"I know, I know, and I've been trying to fix it!" he whimpered. "I thought I had the gene sequence transformation that would turn them all into wolves! Not puppies! Now I have to start back at square one, recreate the sequence and try to see what went wrong!"

"So you just ran off and left Kara to look after them?!" Alex demanded.

"She offered to!" the scientist replied pleadingly. He really didn't want to get shot today.

"Of course she did," J'onn, James and Winn all smirked in unison. Alex shot them all exasperated looks. Was no one concerned about the fate of the Justice League right now except her?

"We'd better get to work on a way to reverse this," Alex muttered warningly, and all of her companions agreed, though three of them were still busy snickering over the story she had just told them...

A couple days later, still no progress had been made. The scientist had mapped out the human and puppy genetics of the superheroes, but he could not find where the connection was. He couldn't figure out what part of the process had turned them all into puppies! And none of the other agents working on the case had better luck than he did.

The only person who remained positive and upbeat through the whole time was Kara, unsurprisingly. She had since moved into the DEO, refusing to leave the compound for even a single second. Instead, she spent every single second inside, looking after her puppy pals. She fed them, bathed them, walked them and played with them and never once left the DEO, despite J'onn's insistence that she needed to get back to CatCo.

"Not if it means leaving the puppies behind!" Kara had insisted stubbornly, and nothing he said or did would change her mind. So while he and the others were working their fingers to the bone trying to fix this, Kara was having the time of her life in puppy paradise, barely even sleeping because she wanted to spend as much time as she could with the puppies. In fact, that entire section of the DEO had since been nicknamed "Puppy Paradise", though whether it was referring to the puppies or to Kara was up for interpretation.

"Kara!" Alex sighed as she watched Kara tucking the Superman puppy into his new puppy bed.

"Shhhh!" Kara replied. "He's sleeping!" Alex rolled her eyes as she joined her sister at her side.

"Ah, and it looks like Aquaman is trying to go for a swim," she whispered, then she pointed to the corner where Kara had set up food and water bowls. Sure enough, the Aquaman puppy had a paw in each water bowl, and was splashing around in them.

"Oh! Sweetie! No!" Kara laughed as she went to pull Aquaman out of the water bowls. He was soaked. Alex watched as Kara dried him off before she heaved another sigh and explained all the progress, or lack thereof, that had been made regarding this little happenstance.

"And they haven't found a way to cure them, have they?" Kara asked, suddenly alert. Alex didn't miss the note of disappointment in Kara's voice. It was clear the girl wanted her friends to remain in puppy form.

"Unfortunately not," Alex admitted reluctantly. She didn't miss the giant smile that spread across Kara's face when she said this. In the background, the Batman puppy was gnawing at another loose strand in the carpet. Cyborg was watching him intently, growling playfully. Kara looked enamored. Alex looked tired.

Another couple of days later, Alex got desperate.

"Alright. That's it," she said. Kara had since filled up an empty crate with water for the Aquaman puppy. Now, he was splashing happily around his new tub, and Kara looked seconds away from hopping in as well. She hadn't been to CatCo in about five days now.

"I'm calling Lena," Alex muttered. And 10 minutes later, Lena came knocking on the DEO's door.

"Oh! My..." Lena blinked as she stepped into the room with Kara and the puppies. Kara had finally caved and hopped into her "tub" with the Aquaman puppy, and now all the other puppies were trying to clamor in as well. Lena could only stare. She had not expected to come in here today to see her girlfriend, fully clothed, splashing around a tiny crate with a hoard of cape-wearing puppies swimming around with her. Was this some kind of dream? And she thought that she had already seen it all...

"Lena!" Kara's grin went from ear to ear as she flopped out of the "tub". Alex, who was standing behind Lena, was at a loss for words.

"Is this why you haven't been answering any of my texts and calls?" Lena replied, unsure of what else to say at the moment.

"You texted and called?" Kara echoed, furrowing her eyebrows as she rung her wet hair out.

"Let me guess, you haven't checked your phone even once this entire time, have you?" Alex crossed her arms, voice finally returning to her.

"Nope!" Kara smiled sweetly up at her older sister before turning back to Lena and offering her a Green Lantern puppy.

"What am I supposed to do with it?" Lena asked as she took the puppy into her arms.

"Cuddle her! She's very sweet!" Kara replied, busily squeezing the Flash and Green Arrow at the same time. Alex could still see the Flash's hind-legs and hips moving at an unnervingly fast pace. In the background, a chair collapsed. The Superman puppy had finally chewed right through one of the legs. The Aquaman puppy barked, splashing some of the water out of his tub and at the Superman puppy. God, Alex's job could get weird.

So the Puppy Paradise received another human member that day. This time, it was Lena.

"Alright, if we're going to fix them, I'm going to need samples of their DNA as humans and as puppies," she said. She had spoken with the scientist responsible for this mess and even though his DNA samples were good, Lena still wanted to use her own, freshly drawn from the sources.

"Fix them?" Kara echoed worriedly, scooping up four of the closest puppies and drawing them close to her chest.

"Kara," Lena pleaded, but Kara only pulled them even closer to herself and further away from Lena.

"Kara," Lena repeated, this time with a bit sharper of a tone.

"Awwww," Kara pouted a little, like an unhappy child, but she relented and gave the four puppies back to Lena.

"Thank you," Lena replied, failing to hide a smile as Kara continued to pout.

Once Lena had her DNA samples, she sat down at the desk that had been moved into the room for her. Upon that desk were several gene sequence scanners and microscopes, poised for Lena to use. But scarcely had she sat down before one of the puppies hopped up onto her lap.

"What the?!" she exclaimed. It was the one with the Superman cape.

"Awwww! He likes you!" Kara laughed, lying on her back and allowing all the other puppies to just run back and forth across her body.

"Is this one honestly Superman?" Lena demanded, not sure if she was disgusted or amazed.

"Uh-huh! He sure is a cutie like this, isn't he?" Kara asked from the floor. Lena gave the puppy an uncertain look before picking it up.

It was so strange for her, to see her biggest enemy (in some sense) in puppy form. Here, sitting in her arms and looking up at her with wide and loving eyes, was the man who was practically a god. Here, sitting in her arms and trying to lick her face, was the man who put her beloved brother behind bars. Here, sitting in her arms and whimpering playfully, was the man she so respected and feared and who had influenced her life beyond comprehension. Here, sitting in her arms as a ball of fur and joy, was the man who made her life a living nightmare ever since Lex was put away. Here, sitting in her arms and barking sweetly up at her and sniffing her blouse, was the man whom she respected and admired and wanted to be more like. Superman had changed Lena's destiny so deeply, and now he was a mere puppy in her arms, so weak and vulnerable, so trusting and affectionate. Did he even remember anything of his Kryptonian roots at all right now? What would Lex have said if he could've seen this?

But Lena's eyes hardened the moment she asked herself this question. She knew exactly what he would've done if he could've seen this, and it was something she didn't want to dwell on. So she firmly set the Superman puppy back down on the ground and shooed it towards Kara, who greeted it with open arms and a giant smile, before turning back to her work.

With any luck, she'd be able to find the exact order in which the DNA had changed from human to puppy. Then, once she had the transformation mapped out in front of her, she could figure out what things must be done to reverse the process. What enzymes would she need to trigger? What genes would she need to suppress? And did exact order matter? And would it require a surgical approach? Or could another machine be built? Or could the machine that was already in existence somehow be engineered to work in reverse?

Lena was so lost in her work that she didn't notice when the Aquaman puppy came up behind her and lifted his leg. But when he began to mark her desk, she noticed it very quickly.

"ARGH! Kara!" but Kara only laughed. The Batwoman and Green Arrow puppies were currently nestled around her head, creating an adorable pillow. Nearby, the Batman and Superman puppies had since engaged in a playfight, each one trying to out-growl the other.

"Uh oh!" Kara giggled uncontrollably as she titled her head to the side to watch the two puppies "argue". This was an instance in which it seemed that some level of humanity still resided within the puppies. The Batman and Superman puppies seldom got along, and sometimes the Batman one would just stare angrily at all the others, but those instances were rare. All Kara had to do was pat his head and he'd start to lick her hand and gnaw playfully on whatever he could get his cute little teeth into. One of the Green Lantern puppies was on its back, paws splayed happily upward.

A few days later, Lena managed to get the gene transformation sequence entirely transcribed out.

"Does this look about right to you?" she asked of the scientist who had created this whole mess in the first place.

"Yes! It does!" he grinned excitedly. The Flash puppy had since come up behind him to wrap all four of his paws around the man's leg. Lena noticed, but said nothing. The scientist, on the other hand, didn't seem to realize at all. And Kara most certainly didn't, far too preoccupied with trying to hold as many as she could all at once. She'd already tried giving them all little piggyback rides, but they kept on slipping off her back.

"So, do you think we can engineer your machine to follow this sequence instead of its original?" Lena asked.

"I hope so!" the scientist replied, then he and Lena shook hands before Lena turned back to Kara.

"Come on, Danvers, we've got to test this thing out and see if we've gotten it right!" she said.

"Awww, what?!" Kara whined, sitting up. Two of the puppies slipped off of her back with an indignant yelp.

"Kara," Lena spoke in a warning tone.

"Do we have to?" Kara whined back.

"Kara," Lena's tone deepened and her eyes narrowed.

"But-" Kara tried one last time.

"Kara!" Lena crossed her arms.

"Yes ma'am!" Kara hopped up at once.

"Good," Lena's face softened into a smirk.

"Jerk," Kara replied with a pout, but Lena only laughed in return.

It was an interesting sight, seeing a nervous scientist, the only Luthor still out of jail, and Supergirl, out of costume and carrying roughly 10 puppies all at once as she flew, perusing through the DEO, but the agents had seen stranger things, so they said nothing as the odd trio and their little band of barking buddies walked on by. Or in Kara's case, flew on by. There was no reason for her to be flying, but she insisted that she wanted the puppies to experience the joys of flight, so she was currently flying along with all 10 of them nestled in her arms. Lena cast one look backward as Kara continued to snuggle the puppies and laugh into their fur, floating at about shoulder level with Lena. It was almost funny to see Kara, flat as a board and "lying" on her stomach, yet still at eye-level with Lena. The Luthor was certain that if this operation were a success, Kara would be devastated, because it would mean all of her furry friends were gone. But not to worry, Lena had already since come up with a solution...

Sure enough, the plan worked. After having Winn, J'onn and Alex work on the machine while Lena and the scientist worked on the genetic transformation, everything was finally complete.

"Alright, Kara, cough 'em up, the machine is ready" Alex grunted as she reached out to take the puppies from her arms.

"But!" Kara whimpered. It was hard for Lena to believe that this love-struck girl was the Girl of Steel, and National City's savior and champion.

"Kara," Lena only needed to make that warning tone and Kara heaved another defeated sigh, handing the puppies to everyone else in the room.

"Alrighty then, let's see how it goes!" Winn muttered, then he powered up the machine and sent the first puppy through...

In a matter of minutes, gone were the puppies and back were the humans, all very confused and disgruntled.

"Urgh, what the heck happened back there?" the Green Arrow demanded, back to his gruff and surly self now that he was cured of being a puppy. Kara looked a little more than disappointed and dissatisfied with the transformation.

"What am I doing in National City?" Batman agreed.

"Yeah, we're certainly not in Kansas anymore, eh Supes?" the Flash grinned up at Superman and elbowed him playfully.

"What happened to us?" Wonder Woman agreed, turning back to face Kara and the others, her arms crossed. And all of them, seeing the Lasso of Truth hanging from her hip, decided that it was best to just tell the truth, no matter how strange it was.

10 minutes later, all of the superheroes had vanished from the DEO, each of them still mildly disgruntled by the story they had been told. But when Wonder Woman's lasso was able to verify that it was the truth, they were forced to accept it, though it was clear that a few of them were less than elated to know what had come over them for the past few days.

"A puppy?" Batman muttered. "A puppy?!" he and Batwoman left for Gotham without looking back. Meanwhile, Superman had grilled Kara hard.

"If you took any pictures or videos, they better not end up online!" he warned.

"Kryptonian's honor," Kara replied, then Superman made the "I'm watching you" gesture before flying off back to Metropolis. Lena had been mildly uncomfortable, seeing his hulking form emerge from the machine, but she said nothing during his little exchange with Kara.

Once he and the others were gone, however, Lena was quick to take a sulking Kara aside.

"How about we go out for lunch?" she asked. "It might cheer you up."

"Maybe," Kara replied, but she didn't sound convinced. About 20 minutes later, though, her mind had totally been changed. For one, Lena had insisted that they eat alone together in her office back at L-Corp. Not only was Kara elated because this meant that it was going to be a very private and personal meal, but then Kara realized that Lena had ordered her as many pot stickers as she could eat.

"And if you want more, I'll be glad to order them," Lena promised. Kara's thanks was nonverbal because her mouth was stuffed with pot stickers.

But the best part of the meal came when Lena's personal assistant arrived, holding a large box.

"For Ms. Luthor," she winked as she set the box down gently.

"Thank you," Lena replied, then she turned back to Kara while the assistant left the office again.

"What did you get?" Kara asked in surprise.

"Open it and see," Lena replied. Kara's scream could be heard throughout L-Corp, and it was quickly joined by high-pitched yips of excitement.

24 hours later, Kara could be seen strutting through the DEO with a little golden retriever in her arms. Lena trailed behind her, laughing.

"LENA AND I ARE MOTHERS!" Kara declared as loudly as she could, and the little puppy howled in agreement with her.

"Arrroooowoooo!" it yipped happily.

"They look just alike, don't they?" Alex whispered to J'onn with a smirk as Kara and the puppy went on by, Lena trailing after them, still laughing.

"I can't even tell the difference," he replied with a soft chuckle. The puppy was wagging its tail a million miles an hour and he was sure that if Kara had had a tail, she'd be doing the same.

"Nor can I," Alex laughed.

"LENA AND I ARE MOTHERS!" Kara repeated excitedly. "AND THIS IS OUR FUR BABY AND WE LOVE HER!"

"Alright, darling, don't you think you might want to tone it down just-?" Lena asked through her laughter, but she already knew the answer.

"Absolutely not!" Kara cut her off, smiling so widely that Lena was sure her face would crack. "This is our child and the whole world has to know! We've already told all of L-Corp, now the DEO needs to know! Every single person here HAS to be an attendant to our puppy shower!"

"Puppy shower?" Lena interrupted with another laugh. "Kara don't you think you're taking this-?"

"Nope!" Kara interrupted again. "I've already got the entire shower planned out! We're christening our little girl with the best party this city has ever seen! Only the best for our little Melissa Luthor-Danvers!" then she buried her face in the puppy's soft pelt and began to giggle wildly again.

A few minutes later, Winn caught sight of the puppy and he wasted no time in snatching it from Kara's hands and raising it high in the air, belting out "The Circle of Life". Kara, beyond ecstatic, began to belt right along with Winn, both of them hopping onto the nearest table as they held little Melissa Luthor-Danvers high in the air together, the most serious of expressions on their faces as they sang. Every agent who walked by couldn't help but stop and stare, stifling laughter as they watched their hero and her friend serenading their puppy with a Disney song.

Lena stood in front of the table upon which Winn and Kara were singing, their puppy still high in the air. Her face was buried in her hands, but she was nearly in tears from laughing so hard. A few feet behind her, Alex and J'onn were in the same boat, J'onn looking like he was about to burst and Alex busily recording the whole thing. Melissa wagged her tail happily. She had no idea what was going on. She just knew that it was a lot of fun! It really was a puppy paradise!

And yes, the SuperCorp puppy is a golden retriever named Melissa, because what else would it be? LOL
