(Spoilers for Borderlands 3)
 
Even with the four Vaults' powers combined to prevent The Great Vault Pandora from being opened; Lilith, Amara, Tannis, Ava and Typhon DeLeon were no match for the awesome might of God-Queen Tyreen. As she took the life of her father, she turned to face the four women, her eyes filled with hunger as she licked her lips.
 
"You know, you pieces of shit really don't know when to leave well enough alone, do you?", Tyreen spoke, "you killed Troy, my BROTHER, don't you think you've done enough? Now you have to try to deny me MY DESTINY?! MY BIRTHRIGHT?!"
 
Her eyes and tattoos began to glow, the familar orange Firehawk wings burning bright as she charged forward towards the women when, suddenly, a drop pod came through the ceiling, landing right on Tyreen's legs and pinning her to the floor. The girls breathed a sigh of relief before raising their guards once more as the pod opened. Out stepped the very last person they could've expected to come to the rescue: Moxxi.
 
"Hello ladies", Moxxi said as she approached her friends, "I know I'm not one for heroics buuuuut...", her eyes glowed blue, tattoos that very clearly had never been on her arms before also glowing with power, "with my new powers, I couldn't just let my friends die right? Especially not my gorgeous new plaything!~" she said, shooting a wink at Amara, causing her to blush.
 
Tyreen looked up at her, her eyes glowing even brighter with fury, "I'm going to dismember you, you big tittied slut!" She reached her hand out, which was promptly grabbed by Moxxi. "Uh-uh-uh! Naughty thing, little girls like you shouldn't play with fire", she slid one of Tyreen's fingers in her mouth and sucked it. "MOXXI NO!" shouted Lilith, "SHE'LL DRAIN YOUR LIFEFORCE!", she began to ran before being stopped by Amara.
 
"Look again Lil!" Amara said, she turned back to the scene, her eyes widening as she saw what Amara was referring to: Moxxi was draining Tyreen's powers, her tattoos glowing brighter and brighter as Tyreen's faded and eventually disappeared altogether. Removing her finger from her mouth, Moxxi remarked "Awwwww done already? Guess that's a "god" for you: you like to be all talk with no walk.~".
 
As she began to walk away, Tyreen began screaming at the four sirens and Lilith; "YOU MOTHERFUCKERS ARE GONNA PAY FOR THIS! I EARNED EVERYTHING, I WORKED MY ASS OFF TO GET THIS FAR, I'M NOT GONNA EVER-", her screaming cut short as Amara threw a piece of debris at her, knocking her unconscious. Moxxi approached Lilith, "So, before we deal with the whole Great Vault debacle...", she gave Lilith a kiss, the Firehawk Wings returning to their rightful owner along with her tattoos.
 
As she pulled away, Ava addressed the elephant in the room, "How the hell did you get Siren powers? Not only that but how did you get Troy's powers to drain Tyreen?". Moxxi chuckled, shrugging her shoulders; "No clue sweetheart but I'm not complaining, I think the tattoos look good on me, whadda you girls think?", posing to the silent and confused group, "You girls are right: not the time to oggle my new features."
 
After a few more awkward moments, Lilith stepped forward, "Alright I have a-", her words immediately cut off by Moxxi; "As do I: Lilith, I want you to transport me, Amara, Tyreen and Ava back to Pandora while you and Tannis head back to Sanctuary."
 
"Are you kidding me? Like Hell am I about to send you three out to die!" Lilith snapped.
 
Moxxi glared back at her, a stare powerful enough to even send chills down her spine; "Did I stutter? Do as I said NOW Lilith."
 
Lilith knew better than to argue with that stare and silently nodded. Amara quickly removed the drop pod off of Tyreen and the four of them were transported back to Pandora and Lilith and Tannis returned to Sanctuary. As the two Sirens left after giving a few words of encouragement, Amara and Ava turned back to see Moxxi sporting a tremendous belly as she licked her fingers.
 
"Mmm-MMM! For such a sour bitch, she sure tasted sweet!" She exclaimed, patting the oversized organ, "Isn't it ironic how Ms. Endless Appetite God Queen is gonna die as food and nurishment for someone else for a change?" Ava looked at her in confusion and before she could speak her mind, the ground shook as a mass of tentacles wriggled their way onto the platform they were standing on: The Destroyer had awoken.
 
"Oh man, we're screwed", Ava wailed, burying her face in her hands as she fell to her knees in despair. Amara and Moxxi simply looked at one another, nodded and proceeded to use their combined Siren abilites to completely obliterate The Destroyer, not leaving a single trace of its existence. While Ava continued rambling to herself about how screwed they were, Amara realized that the Great Vault was still being opened.
 
"How are we going to stop the Vault opening? I thought stopping Tyreen would've stopped the opening."
 
"Guess we gotta brainstorm a little, Sugar.~"
 
"Well... we have the power of three Sirens here, maybe we can push Elpis back?"
 
"I like your thinking Sugar, I love a woman who's strong, sexy AND smart...~ Just one problem though."
 
"What?"
 
Moxxi pointed at Ava, completely lost in her own little world of panic. "Oh right..." Amara said, "Luckily, I have an idea!". She walked to Ava and quickly swallowed her down, the young woman completely oblivious to what just occured. Belching loudly, she took a moment to admire her new belly; as she did, Moxxi stared at her, biting her bottom lip, "Once this is all over, that woman is gonna be my first wife", she muttered under her breath.
 
Amara looked up at Moxxi, smiling; "Alright, let's do this!". Both the supersized stomached Sirens' eyes glowed as they concentrated all their energy at Elpis; Amara was supercharged as Ava snapped out of her panic and began thrashing about her fleshy prsion, blasting her stomach walls with energy and Moxxi had all the power the Calypso Twins had absorbed. Their efforts proved successful as they forced Elpis back, saving Pandora and all the pathetic excuses of life on it.
 
They collapsed on the ground, satisfied smiles pastered on their faces. "We did it Moxxi! We saved Pandora and the universe from the Calypsos!" Amara exclaimed, "Finally it's all ov-", her words being cut off by a passionate kiss from Moxxi. As they continued, the kissing began escalating to making love; all the while Ava struggled in vain to be noticed and released, even Tyreen woke up and began doing the same to similar results.
 
A few hours passed before Lilith and Tannis got worried about the fates of their friends, teleporting back down to them only to be met by the sight of a naked Amara and Moxxi in each others' loving embrace with massive, bloated bellies.
 
"The hell happened here?" Lilith asked, her eyebrow raised in confusion.
 
"It would appear our two Siren allies had consumed some sort of very large meal; well either that or they've contracted some mysterious disease that only Sirens could contract! We should probably quar-"
 
"BBBBBbbbbbuuuUUUUuUUUUUuRRRRRRaaaaaaaaRrRRrrrrrrreEEEEEEOOOooooOOOOOoooooPPPPPPPpppppppPpppPPPPP!!!!!!"
"BBBBBbbbbbwwwWWWWWAAAAaaaaaauuuuUuuUuUUUUUuuRRRRRRRRRRRrrrrrraaAAAAAAuuuuUUUUuuUuuPPPPPPPPPP!!!!!!"
 
Tannis's words were cut off by the two bloated beauties releasing earth-shatteringly powerful belches; Ava's half-digested headphones and Tyreen's mostly-digested coat cape splatting onto the ground by their feet.
 
"Well that answers that", Lilith remarked, "but how did Moxxi and Amara 'have their fun' without Moxxi draining her?"
 
Tannis's eyes lit up with excitement, "I'm glad you asked, my hypothesis is that since the Calypsos were born twin Sirens; they each got half of the same power as opposed to different powers altogether, leaving them with relatively unstable powers. With the universe seemingly granting Moxxi Troy's half of the power; upon draining Tyreen, the power became whole and stable, letting Moxxi control it and be able to interact with other living entities without unintentionally absorbing them."
 
"Huh, well that's convenient; shame about Ava though", said Lilith as she looked at the headphones formerly belonging to Maya's Successor, "Oh well, frankly she was more of a pain in the ass than a help anyways", kicking them off the platform, "I really miss Maya though..."
 
"Missed you girls too."
 
Lilith quickly turned around and her eyes widened: Maya was standing right there, in the flesh, not an illusion, tattoos and all. She ran to her and hugged her, "How? What? How are you here?" Lilith asked, sobbing softly.
 
Maya hugged her back, "I'm not sure honestly, last I remembered was being sapped dry by Troy then I woke up on Promethea. I stole a Maliwan Dropship and came back here. I arrived here when I saw how everything looked fucked up, well MORE fucked up than usual and now I'm here."
 
"Well all's well that ends well! Who's up for some Skag Steaks?" Tannis asked.
 
"Sure but... where's Ava?" Maya asked, Lilith simply pointed at Amara's enormous gut as she belched up a small piece of her hoodie. "Dammit, now I need a new apprentice..." Maya sighed, "...but that can wait, I'm starved and she was a little shit anyways so this time I'll find someone more useful."
 
Lilith smiled as she transported them back to the ship, letting the two lovebirds rest before getting them when they awoke.
