Chapter 1
The only thing the team could process, in the few seconds they had, was that while they team was sitting in the living area a black hole thing popped in the room in front of the T.V., where they had been watching Percy Jackson and the Lightning Thief in their civvies clothing, and a doppelganger of Robin steps out of the hole. Once the process reached their heads they all got into fighting stances that would probably scare a normal person but not this guy, but to be honest someone who steps out of stuff like that are probably not normal, so of course the person in the room just looked at the team as if saying 'Come on, that's the best you can so to scare a guy who stepped out of a black hole?' The kid was wearing black skinny jeans, white t-shirt underneath his black leather jacket. He had sunglasses on and his air was down plainly, to say the least he looked exactly like Robin but he had a white shirt on instead of green

Then the kid opened his mouth to say something and at the last minute decided against it. So Kaldur, instead of the kid, spoke up. "Who are you and how have you infiltrated the security system of Mount Justice" He said in a demanding voice and instead of flinching at the tone as some people would have the boy just smirked.

"I didn't have to infiltrate the security system, mainly because I don't live in this dimension and also because, if you haven't noticed I am as you say Robin but I prefer to be called Agent Grayson. I would think that you want be to tell you about my adventure and if I'm on the side of evil or justice, but I won't tell you guys anything until I get to talk to the person called Batman and please stop trying to read my mind, gosh a guy spends three minutes in another dimension and they already try to pick your brain literary." the boy said.

"Wait, did you say Grayson as in Bruce Wayne's ward Grayson?" Artemis asked.

"Dude, did you not hear me? I said not talking until his dad comes." Agent Grayson said while pointing to Robin.

"Fine, we will do as asked but be warned of the danger ahead. You would have had better luck with us." Kaldur tried to get Agent Grayson to change his mind.

"Please, you're going to have to do better than that to try to trick me. I live in a place filled with lies and secrets, and plus I came here with a mission and I need the so called 'Justice League to help me." Agent Grayson rolled his eyes at the teens.

"Ok, dude we'll lay off and get the Bat but don't say we didn't warn you." Wally said.

"You guys make Batman sound as if he's killed someone." Robin muttered.

"Who says he hasn't?" Conner, the one with super hearing, asked and Robin glared.

"Batman doesn't kill." Robin defended, then a loud cough rang through the air and all eyes were back on the intruder.

"Wow, I could have rigged this place with bombs by this time. You guys trust to easily." Agent Grayson whistled. "I mean you could at least hand-cuff me."

"We don't need handcuffs." M'gann pouted.

"Yeah just follow us and we'll let you see Batman." Robin said.

"Naw, I'll stay here with your leader while the rest of you get The Batman." Agent Grayson said while plopping down on the couch with a sigh. "Aww, why are you watching this movie? It totally ruined the book." Agent Grayson whined.

"Finally!" Artemis shouted and all eyes turned on her. She shrugged "What, he's right you know."

"Artemis." M'gann warned.

"Um hello, guy who came through a portal, looks exactly like one of your partners and wants to talk to Batman here." Agent Grayson said only to get blank stares from the team of superhero teens. "Ok, here's the thing my world is in trouble and I need the Justice League's help, please just hurry up and let me talk to anyone of them."

"Why did you say Batman if you just want to talk to anyone of them?"Conner asked.

"The heck, I give up I am just going to go by myself." Agent Grayson gave up.

"Wait you can't just go get Batman." Wally said.

"Dude, he doesn't even know his way around the cave what makes you think he can get to the Watchtower." Robin smirked.

"Just go get the Batman." Kaldur ordered. The team nodded and ran off. After the team was out of earshot Kaldur turned to Agent Grayson.

"Look no offense but your team is out of order. You are the leader right you should have told them to get Batman to start off with. If I was an enemy I could have beat you guys by now and blown up the um, this base." Agent Grayson said.

"What makes you think that you could have beaten all of us." Kaldur said.

"Please if you've had my training you'd know what I'm talking about." Agent Grayson sighed and put his hands behind his head.

"Do you have a team like this in your dimension?" Kaldur asked.

"Hmm, I don't know if I should tell you anything yet." Agent Grayson smirked. "Aww, what the heck you're the leader. Well, yes I do have a team and I don't know if you would say it was like your team. We don't have any super powers of any kind. But my team does have some of the same people as your team."

"What do you mean 'some of the same people'?" Kaldur asked curiously.

"I said that my team doesn't have any powers, and we certainly do not have any aliens on the team. So that only leaves Artemis, Wally, Roy and myself." Agent Grayson informed. Kaldur was about to ask about Roy but then a computerized voice rang through the mountain.

"Recognize Batman 02, Superman 01, Flash 04, Green Arrow 08, Black Canary 13." Agent Grayson jumped up from his spot on the couch. He turned away from the Percy Jackson movie and towards the voices that were coming from one of the hallways.
