I do not own astro boy or detective conan and this is just for fun.

Chapter 1

Conan took a breath as he arrived in metro city. He sighed realizing he left without a word after Ran found out he was Kudo Shinichi. He looked at the robots and humans and heard his phone ring. He looked at the number and saw it was Ran and tossed his cell phone in the trash. He kept walking and bumped into a robot and noticed it was Astro boy. He adjusted his glasses. " Sorry about that my name is Conan Edogawa and i am the exchange student coming to say with you " He said.

Astro nodded and notices his sensors could tell their was something strange about Conan but left it alone. " Nice to meet you Conan my name is astro " He said as they walked out of the airport. He bumped into someone and did not know who it was. He noticed a hand was offered. He took the hand and noticed the person in the fedora and suit thinking.

Skunk laughed sorry about that " Astro big fan " he said shaking his hand.He placed his fedora on astro head and got in his car and left. Skunk laughed looking at his tablet computer and laughed. " Astro does not know it but he will soon work for us " he said as Jazz handed him his cigar case. He opened his cigar case and smelled an unlit cigar and placed it in his mouth as Jazz placed a lighter near the cigar.

Meanwhile Conan sighed and used his high powered sneakers to destroy the fedora. He noticed astro nodded thanks noticing the technology hidden in the fedora as they got in a taxi as the driver placed Conan bag in the trunk. Conan looked out the window of the cab noticing Astro was silent. " So Astro what are you thinking about " he asked.

Astro sighed " I was kinda wondering how you knew that guy was a criminal " He said noticing Conan scratch his face. He noticed they arrived at doctor O'Shay house. He paid the taxi driver and gave a good tip as he and Conan got out of the taxi. the driver handed Conan his bag and drove away. He unlocked the door to Dr O'Shay and entered with Conan who took a seat on the couch in the living room. He went and made some tea for Conan since thier robot maid was in the shop.

Meanwhile Skunk took a puff of his cigar and laughed that Astro escaped his trap. He laughed and handed Jazz a box of cigars. " give these to astro with a note from a fan " he said. He watched as Jazz placed the box on the doorstep of Dr O shay's with the note and left. He took a puff of his cigar as Jazz got back in thier car and drove off.

Meanwhile Astro and Conan were drinking tea while Dr O'Shay and Zoran. Conan noticed the box of cigars in dr O'Shay hands and noticed the look 22nd gave astro. " Um Nice to meet you Dr O'Shay i am your exchange student Conan Edogawa " He said calling 911. He gave astro a look to scan the box. He heard astro scream. He nodded and noticed Dr O'Shay give them both looks. Both noticed the grim look on Dr O'Shay face and nodded. Conan watched Astro fly the box out of dr O'shay and tossed it in the air.

Dr O'Shay noticed Conan fire a soccer ball from his belt and saw it catch Astro after the E.M.P. hit him. He watched as Conan helped Astro up. He sighed " nicely done but that was reckless Astro and Conan " He said as both nodded. " Well lets eat dinner " He said.

Astro tugged Conan shirt " thanks Conan " He said. He noticed Conan nodded and handed him a journal. He looked throu it and sighed. " I guess i should help Conan deal with his problems since I am sure his girlfriend as Kudo will find him " He thought. He went to wash up for dinner and laughed " tomorrow at metro elementary will be interesting " he thought.

Meanwhile Ran showed up and took a breath as Ai answered the door. " Conan slash Kudo , I think throu away his phone do you know where he went Ai " She asked. She noticed Ai grab a flyer. She took a breath " thanks so he is an exchange student in metro city " She said going to leave. She noticed Ai grab her hand. " Got it your coming too " She said.

End of chapter 1 . Just felt like trying to write a detective Conan and Astro boy crossover. Where Ran finds out Conan is Kudo and he runs away by becoming an exchange student and goes to stay with Dr O'Shay , Astro , Zoran and meets Astros friends and helps save his butt some times and because its conan a body will show up sometime be it human or robot and eventually Conan and Ran will talk things out anyway thanks for reading and please review.
