"What the hell?"
Commissioner James Gordon of the GCPD started into the sky, from the roof of the GCPD building. It was like another earth had appeared in the sky.
"I've been wondering the same thing..."
Gordon span around, and found himself face to face with the Dark Knight.
"Please," he gasped, "warn me next time!"
He shook his head and looked back at the sky, "at least tell me what's going on!"
"From the looks of things," Batman said, "this appears to be an incursion, a point where two universes overlap at a specific point. The earths will get closer to eachother and eventually collide... and both universes will be obliterated"
"Well I'm so glad you're still being your cheery old self," Gordon said dryly, "how do we stop it?"
"The only way i know of is to destroy the other earth, assuming they have superpowered beings too, that won't be an easy task."
"So what do you suggest we do?" asked Gordon, "perhaps this other universe is going to attack us, i'll have to alert the GCPD."
"Most of the Bat-Family are in Gotham, I'll assemble them at the cave."
Gordon turned back to Batman, "good, i'll-" he stopped, Batman was gone, "of course he did, again."
