All was peaceful in the Land of Light.
And then an explosion rocked the capital.
As maniacal laughter, the screams of injured and terrified citizens, and more explosions filled the air, the New Generation Heroes, who were all conveniently present, rushed to the scene. Much to their horror, the being responsible was one all too familiar, and all too unwelcome.
"Father?!" Geed exclaimed in disbelief as the malevolent black and red satanic Ultra, wreathed in flames, turned to face them, his signature weapon, the Giga Battlenizer, clutched in one hand.
"No, that's not your father!" Zero insisted. "I mean, yes, okay, he sort of is, but also isn't, he's the Parallel Isotope of your father, who never created you, and never got the chance to since he was yanked from the past by Absolute Tartarus and never WILL be able to create you - wait, does this mean you shouldn't exist? I'm not clear what sort of time travel logic we're using here-"
"Actually, Zero, I'll have to correct you there," Belial sneered. "I AM his creator...AS WELL AS the Parallel Isotope of him!"
"Say whaaaaat?!" everyone shouted.
"What is happening here?" Father of Ultra demanded, appearing on the scene. "I thought I sensed-" He did a double-take. "Belial?! But I thought you died! And then were replaced by a Parallel Isotope version snatched from the past by Absolute Tartarus. Wait, does that mean Geed shouldn't exist? I'm not clear what sort of time travel logic we're using here-"
"Yeah, we just covered that, Grandpa, he says he's both," an annoyed Taiga said.
"Oh." Ken blinked. "Huh?"
Belial rolled his eyes. "Well, if you'd allow me to explain - wait, is anyone else going to show up, I don't want to have to repeat this story."
Everyone glanced around. A nearby building collapsed. More screams filled the air.
"I think you're good," Grigio said.
"Wonderful. Anyway, after Tregear and I decided to cut ties with the Absolutians, we stole the Giga Battlenizer and Tregear Eye used by our other selves and went our separate ways," Belial began. "The moment I touched this legendary weapon, I had a vision...the memories of my other self surged through me. All his battles. All his schemes. All his FAILURES! I vowed that I would not repeat his mistakes, but knew that I would need great power to change my future...and his memories provided me with a roadmap to obtain that power!"
He gestured at his sinister appearance. "Just like the other me, I sought out the spirit of Alien Reiblood and became his host to become a Reionics with the power to command monsters. By enhancing the Giga Battlenizer - and MYSELF - with pieces of Armored Darkness and emeralds from Planet Esmeralda which I bought legally instead of launching a huge invasion that would immediately draw everyone's attention like my failure of a predecessor," Belial continued as pieces of black armor green crystals grew from his body, the silhouettes of Arch Belial and Kaiser Darkness briefly manifesting around him as several emeralds encrusted in his polearm glimmered. "I was able to track down and capture a hundred monsters infected with my other self's cells to absorb their power for my own, to obtain his strength and malice!"
"His cells - The Devil Splinters?!" Ken gasped.
"Oh yeah, we were supposed to keep finding and destroying those, weren't we?" Z realized. "We Ultra-dropped the ball on that, didn't we?" He scratched his head. "That reminds me, shouldn't the Absolutians have attacked us by now-"
"And thanks to all the Devil Splinters I've amassed, I now have accumulated just about ALL the leftover cells from my other self, adding his power to my own...and there's only one thing more I need to achieve my full power and become the one, TRUE Belial!" Belial bragged.
"The Plasma Spark?!" Zero immediately guessed.
"We'll never let you near it!" Ken declared.
"The Plasma Spark? Not quite, though that is next on my list," Belial sneered. "Since I can't get Childhood Radiation again without blowing up King a second time-"
"Wait, what?" a confused Rosso asked.
"It was this whole thing where he blew up the entire universe and King had to sacrifice himself to fix it, don't worry about it," Orb assured him.
"I instead focused on assimilating my previous form's cells and cultivating the Absolute Particles Absolute Tartarus so generously gave me when he brought me to this timeline, and thanks to all the Devilized monsters in my enhanced Giga Battlenizer, I can now CONTROL anything that has my cells...which means..." Belial grinned at his son.
Geed gasped. "Oh no..."
"You're not going to take him!" Zero declared, immediately getting in front of the other Ultra.
"Oh, it's not just him you have to worry about," Belial sneered. "After all, there are a few other Ultras who've been using my power without my permission...and I'd rather like it back!"
He pointed his Giga Battlenizer and three bolts of green darkness lanced from it, one arcing over Zero to strike Geed...
While the other two hit Orb and Z!
"What?!" Zero cried as all three Ultras started screaming.
"Oh...oh no, that's right, Orb and Z have forms that use Belial's power!" a horrified Ginga realized.
"Well, good thing the rest of us don't," a relieved X said.
Rosso and Blue quickly threw away the Belial R/B Crystal.
With agonized cries, Orb, Geed, and Z transformed.
ORB THUNDER BREASTER!
GEED ROYAL MEGAMASTER!
Z DEATHCIUM RISE CLAW!
Rosso and Blu immediately burst into laughter. The others gave them confused looks. "What?" X asked.
"Breast! Th-Thunder BREASTER!" Rosso guffawed, in tears.
Grigio facepalmed.
The three transformed Ultras, eyes red, leapt in the air and landed before Belial, posing sinisterly. "Yes...YESSSSSS..." Belial hissed as dark auras flowed from the three Ultras into him, his eyes glowing balefully. "And now...for the FINAL piece...BELIAROK!"
"Is that...you...Grampy?" Beliarok rasped as Z obediently handed him the talking sword.
"...Sure, let's go with that," Belial said awkwardly.
"No...NO! BELIAL! I WON'T LET YOU GET AWAY WITH THIS!" Zero shouted, immediately transforming into Shining Ultimate Ultraman Zero and launching at Belial...
Who immediately swatted him away with the Giga Battlenizer, sending him crashing into a building, which collapsed on him.
"No! Zero!" Taiga cried.
"Though let's be honest, who didn't see that coming?" Victory asked.
"...Some days I wonder why I even get up in the morning..." Zero moaned.
"Finally...FINALLY!" Belial cackled, raising Beliarok...and driving him right into his heart, to everyone's horror.
A TREMENDOUS blast of darkness erupted from him, blowing everyone back and leveling the surrounding buildings. Maniacal laughter echoed throughout the system, and King, snoozing in King Cave on Planet King, was startled awake. "Huh? Whozat?"
The darkness took on Belial's form, his malefic grin looming over the Ultras before shrinking back down and coalescing into a figure resembling Belial's ultimate form, Belial Atrocious - which was pronounced A-tro-see-ous for some reason - but as golden as an Absolutian, with more emeralds and armor pieces reminiscent of Kaiser Darkness. "I...AM...ABSOLUTE BELI-wait, why does my voice sound different?"
The New Generation Heroes - and Ken - stared in disbelief. "What? What's going on-" Zero asked as he pulled himself out of the rubble, only to stare incredulously at Belial...
Who was now an Ultrawoman.
A HOT one at that, with an exaggerated hourglass figure, a massive ass and bust, and a breathy, contralto voice.
Beliarok, no longer impaled in her chest, goggled. "Is Grampy a Grandma now?!"
"Why...why am I a woman?!" Belial shrieked, dropping the Giga Battlenizer, causing Orb, Geed, and Z to snap out of his control.
"Father?! Er...Mother?!" Geed exclaimed in disbelief.
"...This is Ultra-weird," Z muttered, eyes wide.
"I...can actually work with this," Belial admitted as she groped her breasts, smacked her ass, and shook her hips, causing everyone to stare at her with very red faces and very confused expressions. "I mean, look at me, I'm gorgeous...I shall be a dark queen rather than a dark king! Yes!" She cackled, dark energy crackling around her. "And I am FAR stronger than my other self was in this form! None of you can stand against me-"
Marie suddenly landed nearby. "What is going on here - Belial?!"
Belial immediately turned bright red. "M-Marie?!"
Mother of Ultra drew the Ultimate Sword, mantle and hair billowing behind her as she glowed with radiant power. "What do you think you're doing?!...And why are you a woman?"
"We haven't quite figured that part out yet," Ken admitted.
"I-I, uh, o-oh gosh, I heard that y-you got a new form, b-but I hadn't realized it was so...so f-fucking big and...b-boobies," Belial stammered as she wiped away some drool, breathing heavily and causing her bosom to heave rather...suggestively.
"What. What is happening right now?" a dazed Zero asked.
"I can't watch," Geed moaned, covering his eyes.
"I can!" Grigio said eagerly, knocking away her brother's attempts to block her view.
"I don't care how strong you've become - or why you're a woman now - but I've obtained great power of my own, and I will use it to punish you-" Marie started.
"P-promise?" Belial squeaked, squeezing her legs together.
Everyone stared. Ken blinked. Marie's eye twitched.
"Oh. Of course this is happening..." she groaned, facepalming.
"This is the best day of my life," Rosso whimpered.
"Mine too!" Blu agreed.
Marie sighed. "Belial, if I take you home, beat you to within an inch of your life, and make you my new plaything - since that's CLEARLY where this is going, despite my best wishes, and I'm pretty sure letting you run off like this would come back to bite us later so keeping you close and taking advantage of your crush on me may be the safest option - do you promise to stop causing trouble? Forever? And maybe TRY being a parent to Geed?"
Geed squealed in excitement at this.
"Does this mean I have a Great-Gramma now?" Beliarok wondered.
"I don't Ultra-know," said Z.
"Ultra-shut up, Z," Zero groused.
"Anything for you, Marie," the smitten Belial immediately promised, eyes filled with hearts. "B-but I've been a very, VERY bad girl, s-so make sure I'm properly...PUNISHED..."
Marie clenched her teeth. Ken blinked. Everyone else stared, red in the face.
"...Can we watch?" Grigio asked hopefully, her brothers nodding in agreement.
"No." An exasperated look on her face, Marie picked up Belial in one hand, causing her to moan in excitement, and threw her over one shoulder. "I'm taking her home. You, ah, may want to stay with one of the kids tonight, Ken."
"I'll see if Ace is free, I don't want to walk in on Taro and Tregear again," Ken said.
"Neither do I," Taiga whimpered.
"So, do we need to start calling him Dad at some point, or...?" Fuma wondered.
"I thought Captain Daddy was our dad," a confused Titas said, causing Ken to facepalm.
Marie flew off, Belial screaming happily.
Everyone stared after them.
"Well, Belial always DID have a thing for Marie," Ken said after a moment. "Never thought it'd be this useful, but...here we are."
"Master, what just happened?" Z asked.
"I have no fucking idea," Zero said flatly.
"You know, what I really want to know is why Belial became a woman," X asked. "How'd THAT happen?"
Some time ago...
"As you requested, Mistress: a Devil Splinter," Lily said, kneeling before her mistress and presenting a glowing orange object resembling one of Belial's eyes, a malefic aura clinging to it.
"Thank you, Lily," Kyukogo said gratefully as she took the cluster of Belial cells, causing her slave to wriggle in joy at the praise. "You know, not too long ago, just being in the proximity of something this wicked would have made me terribly, irreparably ill, maybe even killed me. But now..."
She wrapped her tails around the sliver of malice, channeling her golden divine magic into it. After a moment, she handed it back to Lily, the aura of evil now replaced by a much more benign one which made Lily moan, feeling her mistress's love on it. "Go out and give it to a kaiju, it doesn't matter which one," she instructed. "And then return to me, and I shall reward you appropriately."
Thoughts racing at what her mistress would do to her for this, Lily bowed and thanked the Hegemon profusely before flying away.
"Belial will get a big shock when he absorbs that splinter, won't he?" Nyajou asked in amusement.
Kyukogo nodded. "I do hope Marie likes the gift she's about to receive. After all, we don't do backsies!"
