Note: This AU doesn't belong to me, it belongs to omniglitch/justmenoworries on Tumblr. They have an archive of their own account where they post their omniglitch AU story. This is an AU version of their AU I made, about what if the baby Chills came back to Earth and stayed with Big Chill.

if you don't understand what omniglitch is about, its basically about a glitch caused Ben's aliens to have their own bodies and personalities, while Ben can still turn into an alien, he can only turn into half alien, all the aliens have personalities of their own, you can read it on the original creator's tumblr.

I also made few characters, new aliens for this au, so they don't belong to/or have these aliens in their au.

all right, now they all are finished, let's moved to the story

Chapter 1: shall I be worried?

Big Chill perched silently atop the base's rooftop, their gaze fixed upon the night sky. Lost in contemplation, it had been two or three years since that fateful day.

The young Necrofriggian's birthday loomed only two days away, but a nagging feeling gnawed at Big Chill's gut, suggesting that something was amiss, that danger lurked nearby. For days, nightmares had plagued their slumber, jolting them awake in fear and panic. In these visions, they witnessed their baby Necrofriggians soaring toward the heavens, drifting further into space. Big Chill, fueled by desperation, would take flight, desperately trying to reach their precious offspring. Yet, an ominous darkness would materialize, snatching the babies away one by one. Struggling against an unseen force, Big Chill felt their movements slow, rendering them unable to save their children.

Each awakening found them heaving breathlessly, their surroundings covered in ice from their unintentional power usage.

this has caused him not to be able to sleep for days, while his family is worried about him after noticing he had not been sleeping. But he would always reassure them that he is okay.

But today, shall he finally tell them about his worries, or will he just stay silent, hoping for it to go away soon?

Meanwhile, inside the base...

Located in the Bellwood area, the Omnitrix heroes' base boasted top-of-the-line security measures and cutting-edge technology. Unauthorized entry was strictly prohibited, ensuring protection against various threats. Though the base appeared serene during the nighttime, the sounds of sharpening tools, keyboard typing, and rustling papers filled the air as each hero pursued their own tasks within their quarters or vigilantly monitored for urgent calls from the Plumbers or criminal activities in Bellwood and beyond.

Each hero focused on their individual duties, whether it was training, strategizing for the next mission, or patrolling the surrounding areas. Xlr8 diligently scoured Bellwood and Undertown for any signs of criminal activity. Heatblast rested after a long day of saving lives and apprehending wrongdoers. Diamondhead monitored a map of the United States, keeping an eye out for potential upcoming crimes. Blitzwolf embarked on his customary hike through the forest. Meanwhile, Ben studied for an exam scheduled for the next day.

Inside the base, the sound of blade sharpening can be heard, leading to the attention of two unfamiliar faces among the Omnitrix alien heroes. Seated on a chair with legs crossed, a Sotoraggian donned a sleek black and green armor tech suit. His armor bore some resemblance to the bounty hunter Six Six, but with advanced technological enhancements. He even possessed his own null void gun projector, although he reserved its usage for when it was truly necessary. Engrossed in sharpening his clip-shaped blade, he focused intently on his task. This enigmatic figure went by the name X.X., a reference to the number 10 in Ancient Rome, signifying his identity as 10.10.

Beside X.X. On a towering humanoid planet known as Atasian or, more commonly, Highbreed, there resided an imposing figure named Moss. Engrossed in reading a book about diverse species' cultures, Moss embraced the name given to him by Ben, despite Gwen finding it unfitting and Kevin finding it amusing. Moss possessed surprising calmness and tranquility, despite his intimidating appearance. He greatly appreciated diverse cultures and histories.

Moss's DNA was in the Omnitrix when Ben fought a Highbreed. It took time for his DNA to glitch out with the other alien forces aliens due to the Omnitrix repairing his damaged DNA caused by the Highbreed DNA. When he emerged, his appearance had completely changed, surprising everyone. While back then when the other Highbreeds were still white, Moss's skin color was yellow and gray. Upon witnessing his appearance, he was derogatorily called "inferior," "dirty," and "impure" by the other Highbreeds.

As X.X. and Moss went about their business, a radiant figure made a grand entrance. This glowing being bore a striking resemblance to Ben, but with shamrock-colored skin, luminous green neon hair, and glowing white eyes accented by a hint of green neon around the edges. With a mischievous wide grin adorning his face, he sauntered into the living room, sensing trouble. X.X. halted his activities, captivated by the appearance of this new arrival. The radiant figure, known as Night Shine, the Anodite version of Ben, paused upon noticing X.X., his mischievous grin morphing into an "innocent" wide smile. Both figures locked eyes, their silent exchange with unspoken meaning.

"…."

"…."

"…."

X.X. and Night Shine locked eyes for an extended period, their gaze unyielding. X.X., well aware of Night Shine's mischievous and prankster nature, could sense that he had been up to something, which explained Night Shine's feigned innocence. When Night Shine noticed X.X. scrutinizing him, a mischievous grin tugged at his lips, his manner teetering on the edge of cocky. X.X. felt a tinge of frustration, knowing that Night Shine was about to launch into one of his ridiculous nicknames. Since Sotoraggians were unable to speak, X.X. could only emit gurgling sounds and noises, their language resistant to universal translation. Gray Matter, Brainstorm, and even Upgrade had been tirelessly working on a translation device to enable others to understand X.X.'s speech. Although the device was continually being improved, it still occasionally mistranslated X.X.'s words, leading to comical misunderstandings.

That was why X.X. had chosen not to wear it at the moment, relying instead on gestures and sign language to communicate.

Returning to their unbroken eye contact, Night Shine finally spoke, his tone innocent yet tinged with teasing cockiness. "What's the matter, Xie?" he inquired.

X.X. facepalmed slightly, visibly exasperated by Night Shine's absurd nicknames. Finally, X.X. managed to convey his question through a combination of sign language and hand gestures, "Did you do something?" he signed.

Night Shine simply smirked at X.X, playfully shrugging and dramatically mimicking his sign language gestures. As a dramatic and chaotic theater kid, Night Shine's antics brought a smile to X.X's face beneath his mask.

"NIIIGGGHHT SHHHHIIIINNNEEEEEE!!!!!!!!!!"

However, their amusement was interrupted by loud shouting and screaming. Someone was calling, or clearly shouting Night Shine's name.

Mentacle burst into the room, his reptilian features obscured by a chaotic display of birthday decorations. Streamers draped across his tail, confetti stuck to his scales, and a party hat perched awkwardly on his head. Across his forehead, someone had written "Happy Birthday" in vibrant colors, contrasting against the greenish hue of his skin.

His angry gaze fell upon Night Shine, the mischievous Anodite, who couldn't contain his wide grin despite Mentacle's fury. The room fell silent as Mentacle pointed an accusatory finger, his voice booming with frustration.

"YOU!" Mentacle shouted, his tone filled with exasperation. "I was trying to rest for a mere 40 minutes... 40 damn bloody minutes... AND YOU MANAGED TO DO THIS TO ME!?" His anger reverberated through the room, catching the attention of diamondhead, frankenstrike, and ditto, who heard the commotion, and came to investigate. as Night Shine's mischievous grin persisted, his laughter barely contained.

Mentacle's tail thrashed behind him, knocking over a nearby vase, which one of ditto's copies thankfully catches it, as he continued to vent his frustration. "You think it's funny to constantly prank me, don't you? Well, this time, you've gone too far, Night Shine! I demand an explanation for this madness!" His telekinetic powers crackled in the air, a visible display of his pent-up energy and annoyance.

Diamondhead wore a disappointed and upset expression, his voice tinged with frustration as he addressed Night Shine. "Night Shine, this has gone too far. It's not fair to constantly target Mentacle with your pranks," he admonished, his tone stern.

Frankenstrike shook his head in disappointment, acting like a concerned parent witnessing their child's misbehavior. "Night Shine, you know better than to push Mentacle's buttons like this. Show some respect," he scolded, his voice carrying a paternal tone.

Ditto, unable to contain his amusement, struggled to suppress his laughter behind his many copies. "Heh, Night Shine, you really know how to stir up trouble, don't you?" he chuckled, his voice filled with mirth.

X.X, the ever-observant alien being, watched the situation unfold with a calm demeanor. His metallic voice chimed in, "Night Shine, perhaps it is time to consider the consequences of your actions. Mentacle's frustration is justified."

Moss, facepalming in exasperation, sighed deeply. "Not again, Night Shine. Can't we have a moment of peace without these pranks?" he muttered, his voice tinged with resignation.

Mentacle's anger reached its peak as he shouted once more, his voice booming through the room. "You, you mischievous, annoying brat of energy! Explain yourself!" he demanded, his frustration evident.

Night Shine, still laughing in the face of Mentacle's anger, struck a dramatic pose, his voice filled with theatrical flair. "Ah, dear Mentacle, your fiery rage ignites the stage of our existence," he proclaimed, his voice dripping with exaggerated emotion. "But pray tell, my dear friend, what has brought forth this tempest of fury? Is it the vibrant decorations adorning your form? Ah, but they only enhance your natural beauty!"

Mentacle's eyes widened with fury, his patience wearing thin as Night Shine continued his theatrics. "You..." he growled, his tail lashing behind him as he lunged towards Night Shine, intent on silencing his antics.

But Night Shine, ever agile and quick-witted, gracefully evaded Mentacle's attack, his mischievous grin widening. "Ah, the dance of conflict, a waltz between friends," he continued, his voice filled with playful delight. "But I assure you, dear Mentacle, it is all in good spirits. A touch of chaos to brighten our journey, a reminder that life need not always be so serious."

"you wanna show me how to enjoy life!?!?" Mentacle asked shouting, "SO LET ME SHOW YOU HOW TO ENJOY HAVING A NICE MOUTH SHUT COVERED IN GLUE!!!!" he shouted angrily.

As the two continued the clash between Night Shine and Mentacle intensified. Night Shine, nimble and evasive, dodged Mentacle's attempts to grab him, twirling and leaping around the room with acrobatic finesse. Mentacle, his telekinetic powers crackling with energy, tried to seize Night Shine mid-air, but the Anodite's agility kept him just out of reach.

this noise and chaos caused the others who were sleeping wake up, they quickly came to witness the chaos happening.

As the chaos unfolded, Big Chill, wearing a worried and distrustful expression, walked past the scene, seemingly unaffected by the commotion. Ignoring the unfolding drama, he made his way to his room, his mind preoccupied with deep thoughts and concerns.
