This story is the product of an idea I had, where Conan encounters himself, though I modified it a little. This story will probably be short, like a three-shot or something. A little sci-fi, but not enough to matter. It's mostly a mystery, and a simple one at that. Enjoy it!

Disclaimer: I do not own Detective Conan or any of its characters. I only own the weird Conan.

Chapter One

Ran had always known that Conan was special. He was smarter than anyone else his age, besides Ai, and he always knew what to do in any situation. He reminded Ran of Shinichi a whole lot. That was why Conan's acting weird was starting to scare her.

Flashback

"Ran-neechan! I want candy! Candy, candy, candy!" He tugged at her skirt desperately.

Conan never acted like this. He'd ask once for something, and if he didn't get it, he'd give up, especially over something trivial like candy.

"CONAN-KUN! You can't have any candy! You'll spoil your appetite!" Ran scolded Conan to make him shut up.

"Ran-neechan, you're a meanie!" Conan said sadly, and ran off crying his eyes out, and Ran wondered if yelling at him was such a good idea.

End Flashback

That had been the start. For the next few weeks, he continued acting like a little brat, and Ran was wondering what the heck had happened. He also had stopped wearing his glasses, causing people to wonder why he even wore them to begin with.

Ai was curious, too, if not a little creeped out. His act had been funny at first, especially since she knew the truth, but after a while it had gotten very annoying. When she told him to quit, she was ignored. When she threatened to quit working on the antidote, he'd look at her blankly. And when she addressed him as 'Kudo-kun' he wouldn't pay any attention to her. Something was wrong.

That's why Ai had called him today to ask him to come over to have a physical done on him.

"Edogawa-kun?" He wouldn't respond to his real name anymore, so she was forced to use his fake one.

"Oh, Haibara-san! What's up?"

"Could you come by Hakase's today? I want to run a physical on you."

"You can't do a physical! You're seven years old!"

"Fine, Hakase will do it. Will you come?"

"I'll come, Haibara-san! Bye!" Conan had hung up.

When he arrived, Ai knocked him out with chloroform so she wouldn't have to listen to his childish banter. She brought him into the basement lab and laid him out on the table. She then compared his last health check before the 'change' to the data she was taking now.

'Height and weight are around the same, the changes can be attributed to growth. Blood type is still B, eyesight is 20-20, and heart rate is normal for a sleeping boy. Reflexes are normal, too. No sign of physical trauma.'

Ai was very curious. The physical exam was normal enough, so whatever it was had to be mental. She woke him up to perform it.

"Haibara-san?" asked Conan sleepily, "Why am I so sleepy? Did something happen?"

"No, nothing. I guess you passed out from the fumes from all of Hakase's experiments. Would you like to take a test? It'll be easy."

"Sure, Haibara-san!" exclaimed Conan cheerfully. "What do I have to do?"

"Just answer my questions. Don't play around, dodge the subject, or do anything that might make me mad, alright?"

"Sure! I'll be good!" Conan sat on the edge of the table and looked at Ai in anticipation. Ai began the questions.

"Who are you?"

"Edogawa Conan."

"How old are you?"

"7."

"When's your birthday?"

"May 4th."

Conan had gotten the personal info right, so Ai decided to work on memories, as well as people and things Conan only knew as Shinichi.

"What was the first Holmes novel ever published?"

"A Study in Scarlet."

"What's the name of your biological mother?"

"Fumiyo. Edogawa Fumiyo."

"Who is Kudo Shinichi?"

"He is that famous high school detective. He lives next door, and is the love interest of Ran-neechan."

"What's his current location?"

"How should I know?" asked Conan. "All he tells Ran-neechan is that he's off on some case!"

Ai was shocked. Why would Conan lie about something like that? She tried another tack.

"If a man in a black trench coat with long silver hair approached you, what would you call him?"

"…Probably a man in black, until I learned his name."

"What's the true identity of Chris Vineyard?"

"Chris Vineyard I guess. Isn't she some American actress? Why are you asking me all these random questions?"

"The questions aren't random. You should know all these answers."

"But I don't! The questions are too hard!" Conan complained.

"If I know them, then you should know them," said Ai flatly.

"Ask me more then. I'll prove I don't know what you're talking about!"

"Fine. Who do you love?"

"I don't love anyone. I'm too young to even think about something like that. Though Ayumi-chan is pretty cute sometimes…"

Ai knew there was definitely something wrong now. His response should've been Ran, not Ayumi.

"If I were to tell you that Kudo Shinichi is in this room, would you call me crazy?"

Conan looked around, saw no one else, and said, "Yeah. He's not here."

"What does the name Apotoxin-4869 mean to you?"

"Nothing. It sounds like adult code words for 'You're too stupid to know what the heck this is.'"

Ai realized she wouldn't get anywhere with this, and simply said, "If you let me take your fingerprints, I'll let you leave."

"All right!" said Conan happily. He gave Ai his fingerprints and ran out cheerfully, glad to be out of the lab.

Ai compared the fingerprints she'd just gotten to the ones she had on record. Then she looked at them in shock. "It can't be…"

You can guess what's up with the fingerprints, but what happened? Look forward to explanations later! In the meantime, review this chapter, and tell me if it's any good or not!
