Underground Omniverse

Gammatron: Hey guys. I own no one in this story nor the series of Sonic Underground, Ben 10 Series, or the BlazBlue series. I do own Roll Cyber Sakurai, though, while seanzilla115 owns Haseo, Jake, J, and Jacky while KamenKeybladeDuelist owns Alpha. Happy Belated Christmas and Happy New Year!

Rebel 21: Celebrations

"You're a writer?!"

"Well, yeah," Alpha replied, pausing from his writing, "I have a lot of contacts in the publishing business and, well, I just like writing stories to inspire kids."

"That's amazing," Noel smiled a bit before Alpha handed her a book, "Huh?"

"One of the more recent releases," Alpha replied.

Noel looked at the cover. On it was a figure, roughly the size of a normal adult male. The figure wore a red jumpsuit with bits of silver armor on the knees, belt, wrists, ankles, and elbows. Their face was hidden beneath a mask resembling a blend of a dragon and a knight's helmet. Surrounding the figure was a metallic red Chinese dragon, mirror shards 'raining' around them.

"The Mirror War?" Noel read the title.

"Yep," Alpha nodded, "Right now I'm working on the last of my next set; The Traveler. It'll be unlike any other book since it will involve a hero that travels to different worlds of the previous characters."

"R-Really?" Noel asked before she looked at the summary.

"I have the other volumes on hand as well," Alpha added, his gold jacket glowing a bit before a few more books were pulled out, "See?"

"Oh my…!" Noel gasped before she yelped when a small explosion went off.

"Dammit, Jake!" Ragna snapped.

"It wasn't me!" the tallest of the three Raccoons exclaimed.

"You touched it when I told you not to, dammit!" Ragna growled as he chased after Jake while swinging a wrench.

"Tag, you're it!" Jake laughed.

"What happened?" Alpha asked.

"The engine blew up," J replied.

"Lumpy did it," Jackie added.

"…Where's Haseo?" J asked.

Noel looked behind her, seeing the Hedgefox curled up into a small, trembling ball.

"Um…Th-There, there," Noel comforted, gently rubbing his back (or, at least, where she thought his back was).

As she comforted him, his eyes widened.

"There, there…" a gentle voice whispered as he sniffled, "It's okay~. It's okay~"

Noel raised a brow as Haseo stopped shaking. She yelped when Haseo hugged her, earning the attention of the others (minus Jake). The tallest of the three Raccoons ended up still running around their truck in a circle, laughing.

"I think she's out of your league, dude," Jacky pointed out.

"Oh come now, Jacky," J frowned at the oldest sibling as Haseo slowly stopped his hug.

"G-Gomen…" Haseo apologized, "It…It's just that I almost saw something about my past when you did that and…"

"Oh, that's great!" Noel exclaimed happily, hugging Haseo.

Ragna sighed in annoyance. To think that a mere month ago, he had been in Kagutsuchi and that girl was part of the NOL. Now, he was on a different planet working with the NOL girl and mutated Beastkin…Well, not exactly mutant Beastkin, but that was the best he could compare Mobians to in his mind. He scowled a bit as he looked at Noel, recalling what he had seen when she had first woken up at Sanctuary.

'That face of hers…' Ragna thought, recalling small images, '…Why does she have that face? Why is it that she's like that bitch?'

"Ragna-san," Ragna looked over at Noel, "Um…Are you okay?"

"…Tch. Yeah, I'm fine," Ragna snorted before holding his right arm out to his side, resulting in Jacky's face slamming into it, his body spin around it a few times, and fall flat on his back.

"Quack," Jake quacked.

Noel and Haseo gulped while hugging each other. In the month they had been a team together, the two had bonded from not just their personalities, but also due to the fact of a problem they shared. Noel couldn't remember her past from before she was adopted by her parents.

"You seem to be acting more and more like a mutt, the same as ever."

Ragna tensed up before growling. Alpha sniffed the air and raised a brow. That was strange since roses didn't grow in the area they were in. Ragna growled as he turned to look at the top of the truck, seeing Rachel Alucard standing on the top.

"Usagi (Rabbit)," Ragna frowned, "What's wrong? Getting bored being in the audience?"

"Some scenes cannot be seen on stage," Rachel replied.

"What's she talkin' about? And who is she, anyway?" Jacky asked.

"Rachel Alucard," Ragna replied, not once looking away from the girl.

"This stage is different from normal," Rachel informed Ragna, "Instead of the cycle repeating, the Successor of the Azure replaced Mr. Hero's position, causing the Stage to change itself."

"…You gotta be shitting with me, Usagi," Ragna growled.

"Be wary; the next act that approaches will be one of dangers you've never seen before," Rachel informed before hopping off the vehicle with ease, landing with grace, "If you're interested in a new transportation, follow."

"Damn," Ragna scoffed before he started to walk after her.

"Ragna-san…!" Noel and Haseo began before Alpha hopped off the vehicle.

"If she can get us some new wheels to travel on, I'm going to trust her," Alpha informed as he followed Ragna.

Jacky snorted as he followed next, followed by his brothers. Haseo and Noel gulped before they went last. The smell of roses grew as everyone but Rachel blinked.

"…Crap," Ragna stated.

The group was standing in the grounds of a massive castle. Alpha had to admit that he was impressed with it all. The eternal night sky with a red moon complimented the fearsome castle complete with impaled Jack-o-Lanterns, black stone walls, and a rose garden.

"Wh-Where are we?" Haseo squeaked as he and Noel hugged each other while trembling.

"My home," Rachel replied calmly.

"Th…This is your place?" Jacky gawked, dollar signs appearing in place of his eyes once more.

"Oh, hell no," Ragna scowled as he slammed a fist onto Jacky's head, "You want us to get electrocuted to death?"

"You wish for transport? Then you shall perform various tasks alongside Valkenhayne for the coming celebration," Rachel informed calmly, "That is, if you can handle the tasks. They're not easy for gnats."

Ragna's eye twitched. Jacky's eye twitched.

"Sugoi~!" Makoto awed as she watched the snow fall.

"Can't believe it's almost December 25," Sonia noted as she was polishing her medallion.

"Yeah," Manic nodded as the bus stopped.

"We're here!" Sonic called.

"Where's here?" Makoto asked as she poked her head into the driver's area where Sonic and Roll were sitting.

"It's called Summer Town," Sonic explained, "It's a rare place. Despite it being near the warmer climates, for three days a year-December 23rd, 24th, and 25th-it snows," Sonic explained, "During that time, it's known as Christmas Town."

"This is amazing," Tsubaki noted, "How did this happen?"

"Well, it's been rumored to be a fascinating story," Sonic noted, "You see, the story begins with Santa declaring to be unwell for his annual sleigh ride. So two of his elves came down to Summer Town to see if anyone cared. They got the mayor to agree to something, it's been lost over the years what it was, but they needed to do the impossible; make snow fall in a town where it's always Summer. To get that to happen, they had to see the Miser Brothers, Heat Miser and Cold Miser."

'This is giving me déjà vu for some reason,' Ben thought.

"Anyways, since neither would agree, the two elves and Mrs. Claus-who came along to help convince the two-decided to go over their heads," Sonic continued.

"How so?" Roll asked.

"They went to their mother," Sonic smirked, "Mother Nature herself."

"Ooh…" Manic teased, "They must have been in trou~ble~."

"From what the story says, they were in trouble," Sonic noted, "Anyways, long story short; Summer Town now snows for three days during December each year."

"I've noticed a distinct lack of pollution here," Tsubaki noted as she looked out the window.

"That's because-snrt-Eggman-snrt-doesn't know it exists," Sonic replied, holding his laughter back, "So this place is safe from the fatty."

"…" Ben raised a hand.

"No, this place is like Roll's hometown," Sonic replied, a hand on Roll's shoulder.

"That's good," Ben nodded as he showed the Omnitrix in red, "This still hasn't charged up since our last stop."

"Anyways, here;" Sonic handed the two humans and one Beastkin three bags of Mobiums, "Since we're here, why not go Christmas shopping?"

"Sweet!" Makoto grinned.

"Thanks, Sonic," Ben nodded.

"Are you sure that we can just take this?" Tsubaki asked.

"It's fine, Tsubaki. Consider that payment for helping us," Sonic noted.

"Don't turn it down, he's adamant on this," Sonia whispered, earning a nod from the three.

"So you guys can go start shopping while the four of us…" Sonic motioned to himself, Manic, Sonia, and Roll, "…Go see the mayor for where we need to set the gig up."

"Of all the…" Jacky grumbled as he, Noel, and Haseo were dusting, "Why are we doing this?!"

"To get new transportation," Noel replied.

"…I hate it when you're right…" Jacky grumbled as J was on a ladder held by Ragna.

"Easy…Easy…" J mumbled as he put up some gold and silver decorations.

"A-Ano…Wh-Why are we doing th-this?" Haseo asked.

"Haven't you heard of Christmas?" Noel asked.

"…Christmas?" Haseo repeated, making Jacky stop what he was doing.

"What?!" Jacky screamed as Alpha flew over on a pair of gold wings that ended in turbines.

"What's up?" Alpha asked.

"Haseo here never heard of Christmas before!" Jacky replied.

"…I should've guessed this would've happened with the amnesia," Alpha sighed, "You guys continue, I'll go see Valk and see if he can let me take a few minutes off to talk with Haseo."

"You have all the right to do so," Valkenhayne informed behind Alpha, startling them all, "Ragna, do assist me with making the Eggnog. It appears that Gii and Nago have been trying to steal it for themselves…once more…as they do every year."

"Hey, Sonic!" Ben walked over, carrying a few shopping bags, "What are you doing?"

"Waiting for Roll," Sonic replied as he motioned to the store he was standing near, "Because of that law of her clan's, it's making Christmas Shopping kinda hard to do."

"Tell me about it," Ben rolled his eyes as he sat beside the hedgehog on the bench, "There's a lot of stuff I've never seen before here."

"Really?"

"Yeah. Never heard of some of the books here, like that mystery novel I got for Tsubaki," Ben noted.

"You got her a mystery book?" Sonic asked.

"Well…yeah," Ben replied.

"Okay," Sonic nodded, "Roll and I worked together on getting presents for everyone, so we got her an angel-themed necklace."

"A necklace?" Ben blinked twice.

"Yeah," Sonic replied, "Kind of a way to say 'Welcome to the family.'"

"…Family?"

"Ben, I'll lay it straight; you guys have become kinda like a fourth family to me, right after my first foster parents, my family with Uncle Chuck, and my family in Sonia and Manic," Sonic stated, "Why do you think I didn't want to accept anything less than you guys accepting the money I gave you."

"I…Really? Just…Just wow…Okay…" Ben wasn't sure what to say about that.

"So what'd you get for Makoto?" Sonic asked.

"Wh-what?"

"Honestly, it's obvious you like her," Sonic snorted, "Especially from what I heard about when you told her about this 'Ragna' guy."

Ben's face lit up like a Christmas light.

"I'm back!" Roll called as she walked out with a bag, "I hope you'll like what I got you, Sonikku."

"S-Sure," Sonic nodded.

"Now who's obvious?" Ben smirked, making Sonic glare at him.

"Tsubaki, I really don't have a crush on him!" Makoto pouted as she and Tsubaki walked out of a clothing store.

"But this is just too good. I finally have something to tease you on!" Tsubaki smirked.

"I can't believe how evil you are at the moment…" Makoto muttered.

"I can't help but feel so elated during the holidays!" Tsubaki giggled, "Oh, I can't wait to start asking when your wedding will be!"

"Shut up!" Makoto seethed, her tail twitching in annoyance, 'Good lord, I forgot about how much she acted like this during December at the Academy when we were in our dorm room!'

"Finally!" Jacky groaned as he finished putting up the last of the lights.

"That was strenuous," J groaned.

"Can we do this next year?" Jake asked, hopefully.

"No!" his brothers barked before a snowflake landed on the shortest of the three's nose.

"Oh! It's snowing!" J gasped.

"Though rare, this snow is an annual event," a voice said before Rachel appeared in a swirl of white roses, the red on her attire replaced with white, "Once it melts, the snow provides the water that is used to tend to the gardens."

"Amazing," J noted in awe.

"Such a reaction befits one such as you," Rachel noted.

"…What?" Jake asked.

"Come along; you have another assignment," Rachel informed.

"Already?!" Jacky screamed before pink lightning zapped him, "Okay~Ugh."

"Jacky!" J yelped as the electrocuted Jacky collapsed onto his face into the small amount of snow on the ground.

"…Why are we doing this?" Ragna asked, wearing a military hat with Haseo and Noel.

"Those two are crafty, not once stopping their pursuit of the taste of Eggnog," Valkenhayne informed, wearing a general's uniform, "Sir Ragna, Mistress Noel, Young Haseo, tonight we do battle with the greatest threat…" he tapped his pointing stick on a badly-drawn picture of Nago and Gii, "Mistress's Familiars."

"How bad are they?" Ragna asked in disbelief.

"You know well of their shapeshifting abilities," Valkenhayne informed, "They abuse this in order to devour the Eggnog I prepare so carefully for Mistress's delight."

"A-Ano…V-Valkenhayne-sama…" Haseo began.

"Yes? What is it, boy, please do tell."

"F-Fridge…"

Valkenhayne raised a brow before looking at the fridge, "Strange…The fridge isn't black…"

The 'Fridge' sweated before changing into Nago. Valkenhayne growled a little before his glowed a soft magenta. The magenta energy faded away, revealing a fearsome gray-furred, blue-skinned wolf in the butler's place. Nago let out a feline's scream before he booked it out of there, Valkenhayne barking up a storm in his pursuit. Noel and Haseo stayed behind Ragna until he picked them up by the scruff of their outfits and dropped them away from him.

"Is the stage okay, Ben-san?" Roll asked as she looked over at the Sonic Underground, setting up their instruments.

Upgrade came out of a cable =Yeah= he changed back into Ben, "Nothing was wrong with the electronics."

"Makoto-chan, Tsubaki-chan, anything with you?" Roll asked, putting a hand to a small radio on her head.

=Everything under the stage is a-ok= Makoto replied.

=Eeek! Spider!= Tsubaki screamed before the stage shook a bit.

=…Give us a minute to fix the broken board= Makoto laughed sheepishly.

"Hai, hai," Roll sighed, not able to blame Tsubaki since she had a problem with spiders as well, before she smiled and waved at Sonic.

"Okay, we're getting an 'OK' from Stage Management," Sonic noted.

"Don't you mean our new sis?" Manic smirked.

"Manic, I'm warning you…" Sonic scowled.

"Look lively, you two. It's almost showtime," Sonia hushed as Roll held up a hand and started to count down with it for the three.

"Here's wishing them luck," Makoto spoke before a familiar green light came, "…Ben, what are you doing?"

"Who? Me?" Big Chill asked, "Well…We're in a domed building, so…"

"…That has got to be one of your best ideas yet!" Makoto grinned deviously as the curtains rose.

"Hello, Winter Town!" Sonic called out to the cheering crowd as he noticed Big Chill, "Hope you're all being nice, because our band's gonna get naughty and break a law of nature with a good friend of ours!"

Tsubaki raised a brow as Makoto waved up to her, pointing towards the audience. Tsubaki turned the spotlight from the band to the audience, moving it around before settling on Big Chill floating in the air. Big Chill smirked before taking in a deep breath. He began to fly around, slowly exhaling a vapor into the air. Within a few moments, snow began to fall at a nice pace so it would take a few hours before it could become intimidating (A/N: In other words, it'll take a bit before everyone's waist-deep in snow). Big Chill landed on the stage and bowed as the audience began to awe.

"A patron of Cold Miser…"

"A moth Mobian that controls Winter!"

"It's Jack Frost!"

"So cool~!"

"…Maybe you should've called yourself 'Moth Frost' or something like that, Big Chill," Manic smirked.

"I happen to like 'Big Chill,'" the Necrofriggian frowned, "Well, that and 'Siberia,' but that one sounds more…feminine."

"True," Sonia agreed, "But can you keep it up?"

"Of course I can," Big Chill replied quietly, "As long as I don't overdo it and take the needed five-minute breaks, I should last for the entire concert."

"Sweet!" Manic and Sonic grinned.

"Shall we begin?" Sonia asked her brothers.

"You bet!" Manic replied.

"Hope you guys like this!" Sonic called, "Because we're gonna make sure there's a 'white Christmas' for everyone here tonight!"

"This is…acceptable," Rachel informed on Christmas Eve night, sitting on her Nago-Throne and Gii-Cushion, both sporting multiple injuries, "You have earned your new vehicle."

"Oh, thank God…!" Jacky groaned in relief.

"For tonight, you will be allows to stay in the guest house," Rachel continued before leaving in a swirl of roses.

"W-We should probably go to bed then," Noel noted.

"Yeah, yeah…" Ragna sighed before handing Noel a package, "Tomorrow's the day, so I'll give it to you now as an early birthday present."

Noel blinked. She looked down at the package. It was wrapped up in colorful paper and streamers. She undid it and gasped. In it was a small wooden carving of her with the Bolverk out in an opening stance. She blushed a bit as she hugged it close.

'Th-Thank you…Ragna,' Noel thought.

'Her Birthday's on Christmas?!' the others in the group thought in shock/surprise.

'Lucky…' Jacky thought before he screamed, "It's Christmas Eve night!"

"Oh dear," J whispered in realization, "And we have been travelling and working, not once considering gifts."

"No birthday for Noel?" Jake asked with sniffles and a whine.

"Of course it will! Just without presents and a cake and…oh dear me…" J muttered to himself in concern before Valkenhayne politely gave J a small tupperwave container roughly the size of two cakes.

"A way of my gratitude for the assistance in dealing with Nago and Gii," Valkenhayne smiled a bit, "And please keep the container as well. Just make sure to clean it well."

"Oh my. Th-Thank you, Valkenhayne, sir," J bowed, holding the container to make sure it didn't fall.

Makoto looked out at the snowy landscape, yet she could only frown. It was almost December 25th and that meant…

"…Noel," Makoto whispered before her ears twitched, making her head turn to see Tsubaki getting pulled up to the roof by Fourarms…with Tsubaki tied to a few barrels labeled 'Tsubaki's Eggnog. Touch and you'll be throttled.'

"She wouldn't go without them," Fourarms explained as he saw the perplexed look on the Squirrel Beastkin's face.

"…" Makoto fell over, laughing, "A-Again, Tsub-ba-baki?!"

"Urusei!" Tsubaki blushed, "You know they only sell Eggnog once a year, so I have to stock up!"

"…She's serious, isn't she?" Fourarms asked as he changed back into Ben.

"Oh yeah," Makoto nodded, "Noel and I once went to her bed when she wasn't in the room and the entire space under it was filled with Eggnog cartons all being kept cool by a continuous Ice Magus." Her smile started to shrink as she talked.

"…Is something wrong?" Ben asked, noticing Tsubaki also getting the sad look.

"It's just that…" Makoto sighed, "December 25th is the birthday of a friend of ours; Noel Vermillion."

"Noel Vermillion?" Ben repeated, "You mentioned her before, Makoto."

"The three of us were roommates back in the NOL Academy; Torifune," Tsubaki explained, untying her two eggnog barrels and stabbed one with a faucet so she could pour it into a mug she had with her, "She was the shyest girl in the whole school, not even Mai on her first day was that shy."

"At least Noel didn't pass out from a nosebleed of all things when we bathed together that first night," Makoto added with a snicker.

"Point," Tsubaki nodded before pausing to take a deep drink of her eggnog before resuming with, "Noel had the strongest skills in Magus compared to anyone else in the history of the school. Oh, she seemed like a China doll on the first day we all met." She frowned at Makoto, "And you were quite rude."

"Of course I was. You remember what I told ya about my childhood when it came to school," Makoto frowned before shuddering, "But I'd rather go through it again than eat Noel's cooking."

"…What's wrong w…?" Ben began to ask.

"It was censored, Ben. Censored!" Makoto exclaimed, tears in her eyes as she hugged Tsubaki, "The taste…I still remember the taste. Not even nightmares were that horrible!"

"Censored?"

"Ben, you know about television, right?" Tsubaki asked.

"Yeah."

"You know those shows where they make it so you can't see some things, like faces?" Tsubaki asked.

"…You have got to be kidding me," Ben deadpanned.

"We kid you not," Makoto replied, "It was that bad. And, what's worse, the entire school had to endure it for an entire week!"

"Our other friend, Mai Natsume, was the only one in the entire school that couls eat her food."

"Oh, why did she have to vanish after classes were done? Why?!" Makoto cried out.

Ben sweatdropped as he saw the two girls freaking out as memories of Noel's cooking danced in their heads. It should be noted that one Noel Vermillion was sneezing up a storm at the castle. Eventually, the two had calmed down to continue.

"So what could she do? I know that you're a skilled fighter, Makoto, and Tsubaki's a great strategist," Ben noted.

"Well, Noel had her personal Nox Nyctores…" Makoto noted before Tsubaki began to choke on her eggnog.

"What?!" Tsubaki screamed.

"…I forgot your memories after school went bye-bye," Makoto sighed with a facepalm, "Tsubaki, Ben, I'm going to say this only once; when she pulls them out, dodge for your life. Her Nox Nyctores is a pair of guns known as Bolverk. They make energy shots that can penetrate even the strongest alloys back home. I've seen her use a few shots to let her stay in the air for a bit, kinda like falling with style."

"You mean 'gliding.'"

"No, Tsubaki, she falls with style," Makoto smirked before pulling a picture of herself, Tsubaki, and Noel in the academy from her jacket, "And here's what she looks like, Ben-kun!"

"She looks kinda nice, like a little sister," Ben noted before frowning, "Her weapon doesn't make her act like Jin, does it?"

"Not at all," Makoto frowned, "Though, she does get a bit…robot-ish…when she uses it."

"…How robotic are we talking about?" Ben asked.

"It's like Bolverk just seals her emotions away at times," Makoto frowned, "I've only seen her use it a few times, and each time it just felt that way."

"…Just how bad are these Nox Nyctores?" Ben frowned.

"There's hardly any. In fact, you could most likely count them on both hands," Tsubaki replied, "I'm unsure of how many there are since records on the majority of them were unavailable to students."

"I can tell you this; Haku-Man has one, a little kid with multiple personality disorder has one, Jubei has one, Hazama has one…" Makoto listed.

"H-Haku-Man?! You met the Haku-Man?!" Tsubaki exclaimed in shock, instantly before Makoto with their faces almost touching, "What?! When?! Where?! How?! Speak, woman, speak!"

"Okaaaaaay I think you've drank too much Eggnog. So I'll just take these away and…" Ben began before Tsubaki's sword nearly took his hand, "Ah!"

"Hands off the precious!" Tsubaki hissed, not once looking away from Makoto.

"Okay, me likey," Jacky grinned.

"Cool~!" Jake awed.

"Marvelous," J nodded.

The group stood before a red and black version of the Sonic Underground's bus yet modified to have some motifs involving Ragna and Noel on it.

"I do hope you enjoy this little gift," Valkenhayne bowed.

"It was no simple task to obtain this, so do be grateful and avoid destroying it. An acquaintance on the vehicle is someone I trust to aide you all. However, you must respect his own goal," Rachel informed before the two left in a swirl of roses.

"…Huh?" Noel and Haseo pondered.

Ragna shrugged before walking into the bus. Inside the bus, polishing his Proto-Tool, was the Rook Blanco of this Zone. Unlike the counterpart Sonic's group had met, this Rook had a black jumpsuit on with bits of dark-blue armor on it. He glanced at the ones entering the vehicle and got up to bow.

"A pleasure to meet you all. I am Rook Blanco," Rook introduced himself before holding up a badge resembling the Omnitrix's symbol, "I am here to find and arrest Benjamin Kirby Tennyson."

No Omake this chapter.
