Bold is Japanese. Regular is English. This happens after season 1 and before season 2 for Young Justice

Robin's POV

I chill in the cave on a lazy Saturday. Wally is busy watching the TV. I walk towards the kitchen to get a snack. I grab the chips and is about to eat them when I hear a familiar voice.

"Awesome! I love those chips," the person says.

I turn to see my cousin standing there.

"What are you doing here Kaito!"

"I was in the neighborhood so I though I would come and visit you and Uncle," Kaito explains. "Also, call me Dove while I'm here. I am neither in or out of the uniform."

I sigh as I look at Kaito. He smiles and randomly makes a dove appear. I shake my head at his magic trick.

"Shouldn't you be getting ready for that heist later on?"

"I wasn't the one who sent that. Another reason why I stop by. I was wondering if you and Uncle could go to it," Dove explains as he leans against the counter.

I look at him confused.

"Then why are you in the US?"

"My friend Aoko brought be along. After all, her father is the Inspector I charge of the Kaito KID police force. So he goes to every heist."

"Interesting Cuz. So are you leaving now?"

"I'm going to see Uncle first! I forget the last time I saw him. Probably when you guys visited Japan two years ago," Kaito says. "Well, see you!"

Pink smoke appears and when it disappears, my cousin is not standing there. I sigh and shake my head as I walk over to Wally.

"So who were you talking to," Wally ask me.

"My cousin. The one in Japan that's a magician."

"Ah him."

I nod my head and we just watch some TV.

Kaito's POV

I wonder around the cave in secret. I look for my uncle, who is Batman. We are not blood related, but since he adopted my cousin, hes technically my uncle. I soon reach a big area. I see Batman talking to the Flash. I smile and head over to them.

"Uncle! It's been a while," I call out and he turns his head towards me.

"Who are you," Flash ask me.

"Call me Dove! Batsy is my uncle," I tell Flash.

"Another superhero. How many are you hiding," Flash ask him.

"Not quiet a superhero," Batman tells Flash. "What are you doing here Dove?"

"Can't I visit my family in the US? I mean, when was the last time you visit me in Japan," I say.

"Good question," Batman says.

"Japan? Who exactly is this kid Batman," Flash ask.

"Robin is my younger cousin. I knew his parents before they were murdered. I figured out that Robin was my cousin after meeting him. Don't worry, I haven't told anyone. Family is important to me as it is to him," I tell them.

"Anyways, should you be preparing for the heist?"

"Not me. Someone is pretending to be me. If you look at the picture and the note, you can see the difference. I want you and Robin there just in case things goes wrong. Here's a card so if people ask why you are there, you can say I asked for some help," I tell my uncle as I give him the card.

"And why would we help you," Uncle ask me.

"I'm not asking you to help me. I'm asking you to protect the innocent people there and Inspector Nakamori. My heist are suppose to be fun and safe. I got a bad feeling about this phony Phantom Thief," I tell him.

He looks at the card then at me. I wait for his answer. My uncle sighs and looks at me.

"Fine. I'll send the team on this. Now you better go."

"Ok!"

Pink smoke appears and I leave the cave. I walk towards the hotel that Aoko, her father and I are staying at. The good thing is the fake heist is happening in Happy Harbor. So at least the walk back isn't so bad. Maybe I should visit Aoko as KID. I could warn her about staying safe. Though I already pointed out to Instector how this Phantom Thief he's going against tonight isn't the real one. He alright knew that and everyone is takes extra precautions. I hope nothing bad happens.

Batman's POV

I assemble the team so that I can tell them about this personal requestion my nephew ask me to do. Soon they all enter.

"So what's the mission," Wally ask me.

"This," I say as a picture of the sapphire at the museum appears on the screen.

"Isn't that the stone that Kaito KID is trying to take later one tonight," M'gann ask me.

"Yes. But this isn't going to be a normal heist," I say as a photo of the card that Kaito gave me appears on the screen. "This is a note Kaito gave to me. He wants us to make sure nothing bad happens."

"And why's that? Does he just want to use us to show everyone he can escape with us there," Wally says.

"No. Apparently the man who wrote the note is a phony. KID wants us to protect everyone there," I tell the team.

"And how do you know he's not pulling our leg," Superboy ask me.

"Because I compared the two notes. The one that told the public he was going after this was forged by someone else. You can see that his signature is messed up. It's also in English," I say as I put the two notes side by side.

"So," Wally says.

"So if KID's first language is Japanese, then why is it in English? And it's grammarly correct too. He—"

"He is around the age of the red head. Since that's true, he is still learning English. So he would make a mistake but there is none. Am I correct," a voice says and we all turn to see a 7 year old with glasses on.

"How did you get in," Wally says as he points at him.

"I was brought here," he says as he walks up to us.

"So I see Flash was able to get you," I say to him.

"Yup. So I'm guessing the reason why I'm here is because of the Kaito KID heist being held here tonight. So do you want me to stop him because I got the nickname of 'KID Killer' or is it bigger than that," Conan says.

"He was right. You are pretty smart for a grade student," I say to him.

"I've been told that a lot," he says as he face the team.

"Who is he," Wally ask.

"My name is Conan Edogawa. I'm a detective," Conan tells the team. "I have been given the nickname 'KID Killer' for I stop him from stealing whenever I'm around."

"That's you? It can't be," Superboy says.

"By the looks of it, this place have been used before you guys form the Young Justice team. This is probably where the Justice League worked out of at the beginning. It got compromise and they moved to the Hall of Justice. Though that's just for tourist so their real base is somewhere no one will be able to attack. I'm guess it's a satillite in space," Conan says and everyone have their mouth open up.

"H-how," Wally says in untter shock.

"As I said, I'm a detective," Conan says. "So are we going to work together or am I going to have to do this alone?"

"You sure are a bright kid Conan-Kun. I can understand why KID wants you helping us," Robin says.

"Thanks. Kaito sure knows interesting people. Well, so do I," Conan says.

"Ok. So are we going to start and plan or what," Kaldur says.

"Of course. Now what situation are we in," Conan ask.

I start to explain everything to him. I think I'm going to enjoy have him around.
