A/N: This is my first fanfic. It is set right after the episode when the Justice League meets the Justice Lords and after "Depths" of Young Justice. R&R please.

It was a few days after the whole Justice Lord fiasco and Batman was working on the inter-dimensional machine the Justice Lord Batman created. He took the designs and the machine from the Justice Lord Universe so that no one could start hopping dimensions again. Well, Batman was working on it until a certain scarlet speedster ran into the room.

"Hey Bats. Watcha working on?" asked Flash as he was munching on a box of donuts.

"I'm learning my way around this machine. Now Flash, would you please leave me alone. This machine is very delicate and you are not exactly the most delicate speedster in the world," growled Batman.

"Oh come on Bats," Flash whined as he finished the donuts. "Can I watch if I stay quiet?"

"Fine." Batman continued to work on the machine when all of a sudden alarm sounds started sounding.

"Bats whats going on?" the flash asked.

"Damn it. The other me forgot to mention that he built in a safety protocol," Batman growled as he looked over the device. He tried overriding the system but the machine was already enacting its safety protocol, a portal to transport any unwanted tamperers.

"BATS, Is that safety protocol a giant portal?"Flash tried outrunning the pull of the portal but he wasn't fast enough and he was sucked in.

"FLASH," yelled Batman as he was sucked in as well.

(meanwhile in the Cave)

"Sheesh, why didn't you bring an instruction manual with you?"asked Mal as he kicked Bart's time machine.

"Hello tourist," exclaimed Bart with a flurry of hyperactive hand motions. "Is everyone expected to be able handle their machines. Does a passenger know how to fix a plane or a train?" and a few more sentences in Flash speak, which was too fast for Mal.

"Well, we might as well try one more time," said Nightwing.

They tried running the machine once more, but at the point where normally the machine burned out it began to hum and vibrate. Bart's eyes went wide. His mind was running through so many thoughts. Among them, What the hell?, this thing is supposed to be crashed, I am so moded. And then it stopped. The machine stopped and began to sizzle and fizz out.

And then a portal appeared and out popped Flash and Batman.

Mal, Impulse, and Nightwing just looked at them. Nightwing took out his eskrima sticks and Batman took out a batarang. The speedsters began to get ready for a fight and Mal just ran to alert watchtower and the rest of the team.

Nightwing and Batman both put on bat-glares.
