Prologue: Karakura Town
It was a surprisingly peaceful day in the life of Ben Tennyson, and considering how his days usually went, that was saying something. Normally, he would be fighting alien criminals or going off into space on a mission for the Plumbers. But today, Ben had his rare moment of peace and quiet. He wasn't even being mobbed by fans. While he did occasionally like the attention, sometimes he wished he had his secret identity back so he could have a sense of normalcy.
Ben was relaxing at Mr. Smoothy's, his favorite hangout, and enjoying a delicious smoothy while waiting for his partner to arrive. It had been some time since he and Rook had become partners. It had been rocky at firstdue to Rook being a rookie Plumber and being by the book when they first met but Ben could proudly say that Rook wasn't just his partner, but also his friend as well. Kevin even approved of Rook as well, even admitting that he was cool. Well, second coolest next to Kevin himself.
"I probably should go on patrol and see what happens," Ben absentmindedly thought aloud.
"I'm afraid that patrolling will have to wait another time, Ben."
Ben turned his head to see his time-traveling ally, Professor Paradox, approaching him. Ben had been taken aback at first by the whole steam punk look the professor had taken to, but it actually kind of suited him. It made him look cooler compared to the plain old lab coat he used to wear. It definitely made him look heroic.
"Professor Paradox?" Ben asked. While he didn't mind a social meeting, Paradox rarely, if ever, did so. Whenever Paradox showed up, it usually involved some kind of space-time crisis that Ben needed to help him deal with. He sighed as he got to his feet, threw away his empty smoothie cup, and went to the professor. "So, what sort of universal disaster is about to happen now?"
"You know me so well, don't you, Ben?" Paradox asked in amusement. "However, you're right. There is a universal disaster waiting to occur. But not here."
Ben tilted his head. "Huh?"
"Ben, do you remember that time when you went into another dimension and encountered young Rex Salazar?"
Ben thought back to the time when he had gone to that other universe. E.V.O.s , Providence, Rex. It had been a pretty strange universe, and he and Rex had not met under the best of circumstances, but they had become strong allies and good friends. "Yeah, I remember. Why? Is there something going on in Rex's universe?"
"Not Rex's universe, but another one," Paradox replied. His face became grim. "Eon is up to his old tricks."
Ben groaned. "Eon again?"
Eon was one of Ben's most tricky foes. The first time they had met, he'd tried to absorb all the other Ben Tennyson's of the Multi-verse so he could be the one and only Ben Tennyson. Fortunately, he and Ultimate Ben, a future him from another timeline, had put a stop to his plans.
Paradox, however, did not mention the time Ben had switched minds with his ten-year old self, stopping Eon from acquiring the Chrono-Navigator. As far as history was concerned, it never happened.
"During the events of the time war, Eon was able to escape this universe through sheer chance. And the universe he came to has allowed him to form an alliance with a particularly dangerous group of individuals, and with no Ben Tennyson or even an Omnitrix in that universe…"
"And let me guess," Ben pieced together. "You need me to go to that universe and stop Eon."
"Your insight serves you well," Paradox said humorously.
Ben sighed. So much for it being a peaceful day. "Alright, I'll contact Rook and let him know."
"I'm afraid Rook won't be much help in this other universe," Paradox said regretfully. "The enemies you will face in this universe will be powerful. Even your aliens will have a difficult time against them."
Ben gulped. "Whoa. They're really that strong?"
"Unbelievably so," Paradox said. "But I'm afraid we must hurry."
"We're leaving now?" Ben asked. He kind of thought (or hoped) that they would take some time to pack and stuff.
"Time is of the essence. I will be sure to explain the situation to your grandfather. He will handle things from here in your absence."
"You sure nothing bad's going to happen to my universe while I'm gone?" Ben asked.
Paradox smiled. "Don't worry, Ben. Everything will be fine over here."
Ben took a moment to take this all in. He was going to another universe again for who knew how long. Against people supposedly tough enough to give his aliens a challenge. But this was Eon they were dealing with and he needed to be stopped. He sighed. "Alright. I'm ready."
"Excellent," Paradox beamed. "Now, our destination in this universe is a quaint little place called Karakura Town. Once there you will meet up with two of my colleagues, Kisuke Urahara and Yoruichi Shihōin. They will be able to answer all the questions you will have once you get there."
Am I going to some alternate Japan? Ben asked himself. His knowledge on foreign languages was a bit limited but he did have a decent understanding of Japanese words courtesy of Julie back when they were dating. While he was bummed that they had broken up, he was at least glad she was happy.
"Now, shall we?" Paradox offered.
"Are you sure I won't need to pack?" Ben pointed out. He had a sneaky suspicion that Paradox had already thought of that but it didn't hurt to check.
"Not to worry. I have already made arrangements with Kisuke ahead of time. It never hurts to be prepared, does it?"
Ben grinned. Typical Paradox. Always a few steps ahead of everyone else. "Alright. I guess I'm as ready as I can be."
"Splendid. Now we're off!"
Ben found himself engulfed in that familiar flash of light. He wondered if Paradox ever really needed it or if he just liked showing off now and then.
When the light finally subsided, Ben found himself in some kind of forest. He looked around, wondering where Paradox had taken them. "Where are we? I thought you said we'd be in Karakura Town."
"We are in the forest area of Karakura Town," Paradox said. "A nice place but far from quiet." Paradox's eyes narrowed. "Be on guard, Ben. The enemy is already here."
Paradox pointed ahead. "I have business elsewhere so I'll leave this matter to you. Yoruichi and Urahara will help you in everything you need. Good luck, Ben." And then he was gone.
Ben didn't waste any time and immediately ran forward to see what was going on. The sight he stumbled upon caught him off guard.
In a clearing stood a large man, probably as huge as Humungousaur, and probably just as buff! He was bald, with weird ridges on the top of his head and bushy sideburns. He also had red markings of some kind. Ben could spot a sword tucked in the guy's pants. But these weren't the only things that caught Ben's attention. One was the strange bone-like thing along his jaw. And…was that… a hole in the guy's chest?! Plus, the guy's right arm had been cut off and lying on the ground. Blood dripped from the stump of his arm.
Standing behind him was a smaller, thinner looking guy. And he was pale. The saying "White as a sheet" suited this guy to a T. He had jet-black hair and wore some horned helmet that only covered half of his head. A sword hung at the guy's side.
There were some other people as well. Before the large guy was a boy, maybe around Ben's age, draped in some blackish robes that really contrasted with the guy's bright orange hair. He was holding a long black katana of some kind. There was also a girl nearby with equally orange hair. Ben paused for a moment when his eyes spotted her…assets. Quickly shaking his head, Ben also noticed another guy lying on the ground nearby. Ben couldn't make out much of the guy from this angle but he looked hurt. But Ben was on the alert the moment the large guy kicked the orange haired boy right in the gut.
"Kurosaki-kun!" The girl cried, running over to help him.
"Stay away, Inoue!" Kurosaki shouted in panic. However, it was too late. The large guy ruthlessly backhanded the poor girl, sending her hurtling to the ground. Ben felt his anger rise. He hated it when big guys used their strength to bully the weak.
"Inoue!" Kurosaki cried but then the large guy slammed his fist down on him.
"Shut up!" The man shouted, grinning wickedly. He then started to relentlessly beat Kurosaki. "Hah! I don't know why but he stopped moving! Then die! Die, you little shit!"
Ben clenched his teeth. He didn't know what was going on, but he was going to just stand around and let this happen. It was hero time!
The man raised his arm for the final blow. "It's over, little shit! I'm going to crush you into a bloody pulp!"
"I don't think so!"
Everyone turned their heads as Ben started approaching them. He gave the large man his fiercest glare, but the guy simply looked at him in confusion. "Hey, Ulquiorra," He addressed the pale guy behind him, "Who is this guy?"
The one called Ulquiorra looked over at Ben, who focused his glare on him now. But Ulquiorra wasn't fazed by the glare any more than his friend was. In fact, Ulquiorra looked almost bored. "Just more trash."
The big guy smirked. "So that means I can kill him too."
Ulquiorra looked to the side. "You're wasting your time killing off these trash when you weren't even ordered to."
It was Ben's turn to smirk as he activated the Omnitrix. "I think Humungousaur has something to say to that."
The large guy blinked. "Humungou-who?"
Ben rotated the holographic interface of the Omnitrix. He stopped at what he thought was Humungousaur and the core popped out. Ben slammed the core down. Soon his body was engulfed with the familiar green light. But when the light was gone, Ben found that he hadn't turned into Humungousaur. Instead he had become...
"Diamondhead? Just when I thought this thing was finally starting to work right."
Ulquiorra, his large pal, and the one called Kurosaki all stared in disbelief. This kid who just showed up suddenly turned into some kind of green crystal looking being.
"What the hell?" Kurosaki asked in amazement.
"Ah, well," Diamondhead said, having become used to not always turning into the aliens he wanted. "This should be enough to kick your butt!"
The large guy laughed. "You got guts, kid. I want to see them!" He charged forward to punch Diamondhead.
"Yammy, wait," Ulquiorra called. So the large guy's name was Yammy.
Diamondhead slammed his hands into the ground. Before Yammy could do anything, crystal spikes started rising up! One of them even struck Yammy right in the face. The big oaf staggered from the attack and while he was disoriented, Diamondhead leaped into the air and struck Yammy with a right hook to the jaw. The punch knocked Yammy off balance and caused him to tumble to the ground.
"What the hell?!" Yammy bellowed, angry that he had been knocked to the ground like that.
Ulquiorra on the other hand was studying this new person with interest. Such an unusual power he had. Why had they not been informed of this one?
Yammy got up. "Damn you!" He raised his fist to attack again.
"Hey, watch your mouth! There's a lady here!" Diamondhead raised his hands and began firing shards at his larger foe.
"Gah!" Yammy cried out as the shards pelted his body, forcing him to raise his hand to block them. Diamondhead took advantage of that to run forward and give him a double barrel right in the gut. Yammy doubled over in pain. And for the finisher, Diamondhead grabbed Yammy by the seam of his pants and proceeded to flip him over, slamming him harder into the ground.
"And stay down!" Diamondhead said. He looked over at Ulquiorra. "So, are you up next?" While the skinny, pale-faced guy didn't look like much, Ben's experience with aliens had taught him that looks could be deceiving and even the weakest looking creature could have amazing power. Take Ball Weevil for example, and Nanomech too, not to mention Echo Echo and a few of his aliens which small statures like Grey Matter, who made up for his lack of brawn with brains.
Ulquiorra looked back at him. "That's quite the ability you have. But don't become overconfident. If you were to face against me, you would surely lose."
Diamondhead smirked. "Oh? Look what I did to your friend over there."
"He is not my friend," Ulquiorra contradicted. "Besides…you didn't finish him off."
"Huh?" Diamondhead's question was answered as Yammy started picking himself up again. "Aw, man."
"I'm going to kill you!" Yammy bellowed angrily. He opened his mouth and Diamondhead could make out some kind of reddish ball beginning to form. Diamondhead's eyes widened as the ball transformed into a colossal beam that shot down on him. The explosion engulfed him and the flash could have been seen for miles. When the attack ended, Yammy smiled at the smokey aftermath. "Heh. Serves you right. Now you're toast! It's impossible to dodge my Cero at this…range…what?!"
When the smoke cleared, Yammy was greeted to the sight of a colossal wall of crystal before him. The crystal wall suddenly sank into the ground, revealing a completely unscathed Diamondhead.
"Close," Diamondhead smirked, "But no cigar."
Yammy couldn't believe what he was seeing. This guy's move…was strong enough to withstand his Cero?! "Who…who are you?!"
Before Diamondhead could come up with a witty comeback…
"My, my," a voice suddenly said. "That was impressive, Tennyson-san. Looks like Paradox's praise about you was well founded!"
Diamondhead turned around to see two people suddenly standing behind him. One was a man with messy, light blonde hair whose most notable feature to Ben was the strange white and green bucket-like hat on his head. He also wore clogs instead of shoes. Standing next to him was a beautiful dark-skinned woman with golden eyes and purplish hair.
"For a moment I thought we would have to jump in but it looks like you had the situation well under control," the man with the hat and clogs said. "Well done, Tennyson-kun. Well done."
Yammy growled. "You people just keep coming and coming!"
"Yammy. That's enough."
Yammy turned to face Ulquiorra, shocked. "What?!"
"That's Urahara Kisuke and Shihōin Yoruichi," Ulquiorra explained. "At your level, it is impossible for you to win, no matter how much you try. And that boy," he looked over at Diamondhead, "He is a factor that we were not aware of."
Diamondhead looked back at the two. So these were who Paradox had told him about. Of course, the fact that they had mentioned Paradox by name was a big enough clue. His attention went back to Ulquiorra, who reached out to the air and suddenly some sort of weird portal began to open up behind him. It was a lot different than any portal Ben had ever seen before. To him it looked like the air had suddenly gained a mouth and was opening it up.
"Time to retreat," Ulquiorra said.
"Running away?" Yoruichi demanded.
"What a foolish taunt," Ulquiorra said almost mockingly. "If the three of you fight me while trying to protect that trash at the same time, it is fairly obvious who would have the upper hand."
"Yeah, us!" Diamondhead taunted back. In a flash of green light, Diamondhead turned back into Ben. But his smirk never left his face.
Ulquiorra looked at Ben for a moment while Yammy picked up his arm and went into the portal. Ulquiorra focused his gaze on Kurosaki. "My mission is finished. I will report to Aizen-sama that the "fake" Shinigami he is so interested in is just a piece of trash unworthy of his attention." He looked over at Ben again. Then the portal closed.
Ben let out a breath. "Okay, that was different." He looked over at Urahara and Yoruichi. "Anyone mind filling the hero in on what's going on?"
"Ah, of course Tennyson-san," Urahara said in an overly jovial way. "Let's just gather these people up and we'll be on our way." He and Yoruichi went over to tend to Kurosaki, Inoue, and the other guy. Ben winced at how injured the girl was. Half of her body had been really messed up by Yammy's backhand.
"You okay, Inoue?" Yoruchi asked softly.
"Ku...Kurosaki...?" she groaned.
"He's alright," Yoruichi said as she pulled out a strange pill. "Can you swallow?"
Inoue nodded and Yoruichi gently popped the pill in her mouth. Urahara went over to Kurosaki and the other boy.
"I think it's best if you got acquainted with everyone, Tennyson-kun," Urahara said. "The girl over there is Inoue Orihime. The big guy right here is Sado Yasutora. And this," he pointed to the orange-haired guy, "Is Kurosaki Ichigo."
Ben made sure to memorized each of their names. "So...you guys really know Paradox?"
"He came to our universe a while back," Yoruichi said as she gently picked up Orihime. "We all became good friends after. In fact, he and Kisuke became friends almost the instant they met."
"Ah, it was wonderful to meet such a brilliant man. And the fact that he can travel through time and space made him even more interesting." Urahara suddenly became depressed and pouted. "I often wanted to go other universes. But Paradox wouldn't let me."
"He knew fully well what you would do if you got to go to another universe," Yoruichi said dryly.
"Yes, yes," Urahara said, suddenly waving a fan that somehow appeared in his hand. He looked over at Ben. "So...that's the Omnitrix Paradox told us about."
Ben raised his arm to give Urahara a closer look. "Yep."
"And it can really turn you into a bunch of aliens like that "Diamondhead" you used?" When Ben nodded, he asked, "How many of those aliens that you can turn into?"
"I can't use all of them but I think I can turn into around sixty of them," Ben admitted.
Urahara gave a smile. "Is that so? Well then, things are going to be really interesting with you around, Tennyson-kun."
Indeed they would be as Ben was going to have one of the most intense and craziest adventures in his life. This wasn't simply Ben fighting human super-villains with freaky powers or alien technology. He wasn't even fighting alien villains or warlords. Now, he was in a whole new world with its own rules, and Ben would have a pivotal role in the events to come.
End of chapter

I know that you're most likely impatient for the next chapter of my Transformers story and Bleach: Ultimate Alien. Relax all of you. I have not given up on those stories, nor will I be starting any more new ones. Aside from the first three chapters to this story, all future chapters will wait until I have made more decent headway in Bleach: Ultimate Alien. Let me know what you guys think, feel free to compare between my two Ben 10/Bleach crossovers. And if you have any flames, keep them to yourself cause I'm not interested. Aside from that, enjoy.
