So... my sister (rarmaster) and I had this crazy idea. What would happen if my Vexen were to end up in the universe that she sent the Riku Replica to? Or, rather, what would happen if, for some reason, any of my Vexen Replicas were to meet up with any of her Vexen Replicas? And thus, this hilarious thing is the result. I wrote this chapter, but she will write chapters to come. And I promise you, laughs will abound. If you want to know more about her KH universe, I suggest reading Falling to Pieces. Good story. Umm... that's about it. Please read, enjoy, review! If you have any questions, you can PM me or her and we can explain the wonders of the Replica Programs.

Prologue

Vexen Replica Pi was bored. He was practically created bored. With fifteen other Replicas before him, he didn't have much of a job to do—at least, not that he could figure. So, as bored as he was, he decided he would do something that all the Replicas knew was impossible to do—get into Castle Oblivion.

No one knew quite why Castle Oblivion was sealed off. Rumor had it that the Master himself sealed it off. Though, other rumors just stated that the Castle had a mind of its own and sealed itself for reasons only it knew.

But that wasn't going to stop Pi from trying to get into CO anyway.

When he was sure no one was looking (not that it really mattered, it's not like the other Replicas would know where the dark corridor led and they were free to use them as they pleased), he opened up a dark corridor and tentatively stuck his hand through. He had been told that if a dark corridor couldn't go somewhere, it would be like he was being electrocuted.

However, no such electrocution occurred. Raising his eyebrows, Pi stepped through.

He had never been to Castle Oblivion before, but he knew what it looked like because he had many of the Original Vexen's memories. From the looks of this place, it was Castle Oblivion alright. But, something about this place didn't seem right. For starters, there were way too many Vexen's around. Last he knew, there were only a few remaining in Castle Oblivion. Nonetheless, one of the Replicas stopped and looked at him.

"Where have you been?" he asked. "Wait, what number are you?"

"Number?" Pi wondered. "Uh… I'm called Pi!"

The other Vexen Replica (number 29, but Pi didn't know that) smacked his forehead.

"I should have known it was you, 6, come on, let's go to your nice, shiny white room…"

Pi was very confused and wanted to tell this other Replica that he totally had the wrong guy, but at the same time, he wasn't quite sure of what was going on. This couldn't be the same Castle Oblivion. For starters, he vaguely knew that Vexen Replica Number 6 (part of the Master's original collection of Replicas) failed and was disabled.

His mind began to work out possible solutions to this problem. He was modeled after the greatest Academic of all time. He should be able to figure out what was happening here.

The first logical explanation he came up with was that someone had reinstated six, but why? The second logical explanation was that he had actually been electrocuted and this was a dream. The third logical explanation was that he was actually in some form of parallel universe, which had been known to happen when travelling by dark corridor. The Master mentioned something about a man named Edd who broke a few boundaries a while back and there were holes in the universe that you could theoretically slip through.

All of these thought processes occurred in three point two seconds. In that amount of time, the other Vexen Replica had time to cross the distance between the two of them and grab onto Pi's wrist. (Which he sort of felt was a bit of a violation of his privacy.)

However, he did not have much time to be annoyed, for as soon as the two Replicas touched, they both came to the same conclusion.

"You are from a parallel universe!" 29 exclaimed.

"Explanation three was correct!" Pi exclaimed.

"Would you like to explain how you got into this universe?" 29 asked.

"I am not quite sure," Pi said, thinking. "I was trying to get into Castle Oblivion, for in my universe it is sealed off for some reason. But, I was trying to get there anyway and I ended up here instead."

"That is very interesting, I assume it has something to do with the Edd interference."

"Oh, so you know of Edd also?"

29 nodded gravely. "He caused a significant amount of disruption here and we are still in the midst of recovering from it."

"I am truly sorry," Pi said.

29 shrugged. "It is not your fault I'm sure. Anyway, have you been here long?"

Pi shook his head. "I just appeared and was calculating exactly why there were so many Vexen Replicas about when you asked me who I was."

"Oh! To which I must apologize with confusing you with Number 6. He's not quite right in the head. We just have never had the heart to disable him. Lately, he's also taken to calling himself random foods. Therefore, I assumed you were him. What is your correct name?"

"Pi."

"Ah, like the letter. So I take it you are the sixteenth in your collection?"

Pi nodded.

"I am Number 29," 29 said.

"Pleased to meet you," Pi said.

"Likewise. On that note, I must be off, I need to find Joseph."

"Joseph?"

"Long story, you are welcome to come along with me if you'd like."

"I just might enjoy that," Pi replied. "I have been itching to collect some worthwhile data. And what better place to do that than in a parallel universe!"

29 smiled. "I appreciate your pursuit of data. And perhaps it will be better this way, if you had happened to run into 23 things might have been troublesome."

"Really, how so?" Pi asked, pulling out a notebook to start taking notes.

"We've been having some problems with rogue replicas," 29 said sadly. "Unfortunately, the original Vexen was destroyed and the Replica Program was placed under the care of Saix."

Pi twitched. He did not like Saix in his own universe. And from 29's tone, he gathered that Saix was equally well-disliked. 29 seemed to gather what Pi was thinking.

"I see you understand what I am talking about," he said. "On that line of thought, some of the other Replicas, I am ashamed to say, started working for Saix. We just haven't had the means to disable them on such a large scale. Technically, we are the rogues because we are not working alongside Saix. However, to us, they are the rogues, for they are the ones who have betrayed our Master's intentions."

Pi was frantically scribbling notes, as well as analyzing the things 29 had just said. However, it was about at that moment that he heard a loud splat and his paper was smattered with reddish-orange liquid. He looked up at 29 and was rather shocked.

29 had a tomato on his face.

"Bulls-eye!" came a childlike yell from behind him.

"JOSEPH!" 29 screamed, wiping the tomato off of his face.

Pi turned around to see a short boy with black hair and brilliant blue eyes. He looked to be about eleven or twelve. From a distance, Pi couldn't be sure what the boy's status as a being was. He looked to have more heart than a Nobody, but he had no clue who the boy could be a Replica of.

The boy laughed and ran off, 29 chasing him at his heels. Pi followed, intrigued by this incident.
