SZ: Hey, guys. Now before you ask, this is something I want to try. It's not gonna be a triple crossover like AR and AR Redux, it's just gonna be a regular crossover between Ben 10(Omniverse to be precise, but with Ben being a bit more mature.) and Blazblue(a mix of Continuum Shift and Alter Memory kinda). And before you say 'ugh! Again with those two?! Why?!' I have my reasons, okay!...Ugh...look, I'm sorry. Just...since this one A-hole left an anonymous review for AR Redux, I've been feeling...cruddy...uninspired...I know I've managed to make FiT and my Fimfic exclusive story Neighpon Tales, but I had Z0 and Pikatwig's help with the former and latter respectively. Anything else….*sighs*I became a fanfic writer to create stories, to possibly get good reviews...not get flames or reviews like that...and it's because of a-holes like that that I hardly feel inspired anymore. I try to get inspiration through comics, video games, and Youtube...but nothing. Hopefully this story will help me feel inspired to write stories again. Now then, I don't own anything in this story, nor do I own the Ben 10 series, or Blazblue series. I do though own any OC aliens that appear in this story. Now...let's begin.

Ben yawned as he walked through the streets of Bellwood...like every other day. A year had past since the final battle against Maltruant, and things have gotten kinda...dull in his opinion. No villains or rogue aliens have attacked him or earth in the past year...no Vilgax, no Khyber, no Forever Knights, no Syphon, heck, not even any sign of the Vreedle Brothers, or Dr. Animo. He's glad the earth is safe now and all, but...he felt...like something was missing. But what? He could ask his friends and all, but Gwen was still in College, Kevin was busy with his Auto Shop, and Rook is out on patrol for the Plumbers.

"...Maybe a smoothie or something might cheer me up," the young adult muttered to himself as he walked further down the sidewalk before he stopped in front of a store window, the surface allowing him to see his reflection.

He had just turned seventeen this year, and decided to go with a new look of sorts. His hair grew out a bit, reaching down the lower half of his neck. His current attire consisted of a pure black shirt underneath a dark green jacket, a pair of grey jeans, and white and dark green running shoes. One thing he noted was that unlike his other outfits in the past, his jacket and shirt didn't sport the '10'. He then looked down at his wrist to look at the Omnitrix.

Seven Years...it had been seven years since he got it, and did so much good with it. But now, with little to no threats left, things were pretty normal for him. No fans asking him for autographs, no crazed fan girls hounding for him, no bad guys coming after him, no nothing. He felt like an average, normal person for a change. Not that he minded, but deep down...he wished something would happen.

"Greetings, young Benjamin," a voice spoke, making Ben turn to the left to see a familiar time traveling professor, "Quite a lovely day out, isn't it?"

"...Yeah...I guess it is," Ben nodded slightly.

Professor Paradox, a man Ben met two years ago during the incident with the DNAliens and Highbreed. Due to an incident back in the 1950's, Paradox has been able to any point across Space and Time, except certain places that is. But despite that, Paradox has been a valuable ally to Ben, and was able to help him defeat the likes of Eon and Maltruant.

"...So is something up?" Ben asked him, "Normally you wouldn't meet me here like this unless there's a dire situation or something."

"That is true, Benjamin," Paradox nodded, "But first, tell me. How is your Japanese?"

"...Uh, okay I guess. Been taking a few lessons online and stuff," Ben shrugged, "Why ask?"

"Let us say where we're going, it be a bit essential," Paradox explained as he pulled out his pocket watch from his coat pocket, "Now come on, Benjamin. Allonsy."

"Al...what now?" Ben blinked

"Just a saying an old friend of mine once said," was all Paradox said as he and Ben disappeared in a flash.

(?)

Within a second, both Ben and Paradox appeared in a town...or rather...what used to be a town as there were ruined buildings and rubble strewn about on the ground.

"...Where...are we?" Ben whispered, his eyes widening upon seeing the destruction before him.

"One of the many towns and cities destroyed by the Black Beast," Paradox explained in a grim tone.

"The Black Beast?" Ben repeated at that.

"Look in the distance," Paradox instructed as he pointed forward.

Ben blinked a bit before he followed the professor's instructions and looked ahead...but his eyes widened in complete horror and shock upon what he saw.

Even from far away, the creature...no. The monster he saw in the distance was truly a horrifying sight, its size easily making Way Big small in comparison. The monster resembled a demonic eight-headed dragon with obsidian black scales, and crimson red 'cracks' all over its body. Just from looking at it alone, Ben could feel the creature's demonic red eyes piercing through his soul.

"Do not worry, Ben," Paradox spoke as he put his hand on Ben's shoulder, making him snap out of his fear struck state, "I know it looks terrifying, but it won't move for yet another six months."

"Six mo...wait," Ben began as he looked at Paradox, "Where and when exactly did you take me?"

"Japan, circa 2107, the era of the Dark War."

"2107?" Ben whispered in complete shock, "Th...this isn't an-"

"No. This isn't your world's future, Benjamin," Paradox explained.

"...Oh...right. Dimensional travel expert and stuff," Ben chuckled sheepishly before gaining a serious expression, "But in all seriousness professor, what is this Dark War you mentioned?"

"...I shall explain, but take heart that this is very serious, Benjamin," Paradox stated in a firm tone, earning a slight nod from Ben, "Good. Now then...Back in 2100, the Black Beast had appeared with one goal in mind...the complete annihilation of mankind. In order to accomplish this, the creature unleashed a Substance known as Seithr throughout the world."

"Seithr?"

"A highly dangerous substance, Ben, especially to humans. If you're exposed to too much of it, it will either kill you, or transform you into something that is not even human anymore."

Ben couldn't help but gulp at that before his eyes slightly widened a bit when he realized something.

"Wait, if that's true..and the Black Beast ran through here, d-"

"Do not worry. As long as you're near me, Seithr will not have any effect on you," Paradox explained,causing Ben to sigh in relief, "Now then, let us continue. Throughout its lifespan, the Black Beast had destroyed about half the world's population…" he then looked down with a grim, yet sad look on his face, "All those lives...gone."

"...But," Ben spoke up, a worried tone in his voice, "Hasn't anyone tried to beat it?"

"No. The beast was too powerful for anyone to defeat it..however, there was one man that was able to delay the beast for a full year," Paradox explained, causing Ben's eyes to widen, "No one but a few individuals knew the man's name, and that name was...Bloodedge."

"Bloodedge?"

"Yes. Like I mentioned, it is thanks to him that the Black Beast has become inactive," Paradox re-stated, "And in six months from now, it'll resurface again and resume its missions. Thankfully during this time, humanity had developed weapons to combat the Black Beast: Ars Magus, and Ars Armagus."

"I see…" Ben noted.

"Yes. It took about three years or so, but thanks to the power of the Six Heroes-six individuals who had come to help humanity in its time of need-, the Black Beast fell, thus ending the Dark War," Paradox explained further before a slight frown grew on his face, "But with the fall of the Black Beast, a large series of events had begun to transpire."

"What do you mean?"

"...One of the Six Heroes, Yuuki Terumi...had betrayed his former allies by killing Nine and Platinum."

Ben's eyes widened further at that before his blood began to boil in anger. This Yuuki Terumi guy...what kind of man would betray his allies like that, especially after dealing with a monster like the Black Beast?

"After hearing of this, Mitsuyoshi and Hakumen, two more of the Six Heroes, had tracked down Terumi and managed to seal him away. But…"

"...But what?" Ben asked, "What happened?"

"I'll tell you, but first…" Paradox paused as he held up his pocket watch once more, "Let us continue this elsewhere."

"Wh-" Was all Ben could say before he and Paradox disappeared once more."

(?: 2200)

Within a flash, both Ben and Paradox reappeared in another area. Though unlike the destroyed town, this area was more...tranquil and calm. Within the area were various trees and flowers, a few seemingly growing out of the many large fountains there. On some of the fountains were statues, one being a devil wielding a scythe, and the other depicting two armored angels and a unicorn, the fourth statue seemingly missing its head and arm. Lasty, there were a few stone bridges above some of the rivers created by the fountains.

"Uh...now where...er. When are we?" Ben asked as he looked at the area.

"Well first; we're in 2200, 93 years after the defeat of the Black Beast," Paradox explained, "And as for where we are, we're in the Hanging Gardens, one of the many areas located within the 13th Hierarchical city, Kagutsuchi."

"I see…" Ben noted before blinking, "Wait. 13th?"

"Yes. You see, Benjamin. After the events of the Dark War, the world was still covered in hazardous Seither, killing off many humans and animals. Due to this, humans were forced to live in high altitude areas, such as mountains and such, and built cities there."

"I see...and I'm guessing most of those cities are the Hierarchical ones?" Ben guessed.

"Correct."

"Ahh..." Ben noted, "But...why bring me here?"

"...Remember when I said Yuuki Terumi was sealed away?" Paradox asked in a serious tone, earning a slight nod from Ben, "Ten years ago, he managed to escape."

"Seriously?!" Ben gawked.

"I'm afraid so," Paradox nodded, "Until now, he's been hiding in the shadows, scheming and plotting his next move…" he then frowned, "And he's done so many terrible things since he's gotten out."

"...Tell me where he is then. I-" Ben began.

"You will do no such thing, Ben," Paradox said in a very stern tone, "Terumi is nothing like Vilgax or any other foe you've faced. If you spot him or run into him, do not, and I repeat, do not fight him. Do you understand?"

"...Fine," Ben sighed, but who was he to complain. Telling by the tone Paradox used, and the fact that Terumi was one of the Six Heroes, he knew this guy spelled major trouble, "But...why did you send me here if I can't deal with him?"

"...While you cannot fight him, I want you to at least interfere with his and the Imperator's plans."

"I s-wait..Imperator?"

"You could consider the Imperator...someone that even Terumi fears."

"...I-I see…" Ben noted, gulping a bit upon hearing that, "A-anything I need to know?"

"Just this. Be careful…" Paradox warned him, "The N.O.L has eyes everywhere...so to speak."

"...Gotcha," Ben nodded, "But...if I may ask, what's the N.O.L?"

"The group Terumi and the Imperator are apart of," Paradox explained, "You could consider them the police of this world..only they have a severely grave rule," a large frown appeared on his face, "Those who go against the Imperator, no matter how old they are, are sentenced to death."

"What?!" Ben gawked at that before growling a bit, "That's going too far."

"Indeed. You can thank the Imperator for making that rule," Paradox stated as he looked at his pocket watch, "Now before I head out, I have something to give you." He then reached into his coat pocket and pulled out a small bag.

"What is it?" Ben asked, his anger having died down as Paradox handed him the bag, the young adult feeling what appeared to be coins in it, "Coins?"

'"Close. Platinum Dollars," Paradox replied, "They are the currency of this world. One coin alone is worth...oh say, 100 Yen."

"...And how much did you give me exactly?"

"Hmm...I'd say...around 1000-1200, just enough to get you around and such."

Ben nearly fell backwards upon hearing that. If what Paradox told him was true, then...he practically gave him...well, let's just say a lot.

"A...are you sure it's okay for me to have this much?"

"Of course. Just make sure you hold onto it tightly. There are some shady characters out there," Paradox warned, "Well, I'm afraid I'm must be off. But before I go, I have one more thing to say."

"What's that?" Ben asked.

"Try not to faint," Paradox said with a slight, teasing smile as he disappeared in a flash of light.

Ben couldn't help but blink at that, wondering what Paradox exactly meant by that. He then just shrugged it off, putting the bag of Platinum Dollars inside his pants pocket and walked off. He figured while he was in this world, he might as well get a good look around the area and such.

SZ: *sighs*sadly, this is all you're going to get for now. I would've written more but…*sighs sadly*one of the cats I helped raised around my neighborhood died…*sniffles*I really loved that cat...she was such a sweetie. At least she's up in heaven now, running with many other kitties. I...I'm sorry….I need to go. Until Next time, I'm Seanzilla115….bye.
