Crossing Over

Terry McGinnis stood unmasked in the Batcave as Bruce Wayne was using the Batmonitor, hacking the security system to WaynePowers Industries. The organization has beefed-up security with the announcement of a new, revolutionary product – a machine designed to view other worlds.

"What do you see?"

"The science is experimental, the theories used are controversial. If it doesn't work, this thing will cause an explosion large enough to wipe out all of Gotham."

"So, my cue to break in, make sure nothing goes wrong? Shut it down?"

"Stop the people going after it. The security is easy enough to hack and technology this new – experimental as it may be – will fetch a high price on the black market. Someone is going to try to steal this."

"You've been through this a lot, haven't you?"

"Runs like clockwork. Security is simple. Watch the invisible lasers and don't let anyone see you."

With that, Terry left the Batcave for WaynePowers Industries. He activated stealth mode as he hopped from the Batmobile to the roof. Batman glared inside to see three scientists working on the machine. At 10:00pm, the men attempted to leave but were greeted by Jokerz. One was spliced to meet the form of a hyena; Terry knew he ran into this gang before. Batman crashed through the glass panels in the ceiling as the alarms were already sounding. The Jokerz had used gas pellets to make the scientists laugh to their submission.

"Aw," taunted the lead Joker. "Bats' missing all the joy. What do you say we make him laugh?"

A couple of female twin Jokerz spun to Batman's side. They both kick him at the waist, Batman jumping out of the way and tossing a Batarang. The device launched a metallic wire that spun around the twin Jokerz and rendered them immobile. The hyena Joker suddenly latched onto Terry's shoulder, causing agonizing pain and Batman crying out by the surprise attack. As he shook off the beast, another member of the gang took a beaker filled with a chemical of some sort, smashed it, and headed toward Batman with the shattered glass. He, in turn, kicked the Joker to the side and disabled his weapon. Then, Terry flung him into the hyena as he was rising. Batman turned to see the lead Joker about to throw the switch on the experimental machine.

"Forget the cash, Bat-Freak! I'm in for a whole new world to do what I want without seeing a freak in a costume! See ya on the flip-side, punk!"

Terry attempted to jump and use a Batarang to capture him, but unfortunately to suit jammed. As he landed, Batman flipped into the portal after the Joker. Going through, his whole world span around him. Terry felt as if his head was about to split in two. He began to feel lightheaded as he moved everywhere, yet nowhere. There was a sudden thud as he hit the new world, catching a glimpse of the Joker unsteadily walk off. The portal closing caused the ground to shake slightly. Batman became disoriented to a point where he completely blacked out in this strange, new world.

Peter Parker was in his apartment, changing into his ordinary clothes after a morning's patrol. He pulled down his shirt, finally hiding his costume completely underneath his clothes. Peter was about to open the door when he heard a familiar roommate.

"Parker! Wake up! You need to stop by the DB and arrange my meeting with Matt Murdock!"

"Ugh…" Peter complained through the door, attempting to create the illusion of him just waking up. "Why can't you just do it?"

"You know I have to close the deal on the O'Rian case, and Mr. Murdock is a very famous lawyer – it's like he knows when the opposing side is lying! His partnership could make my career and you're not going to deny me this!"

Peter reluctantly agreed with his roommate, Michelle, and went swinging as the Amazing Spider-Man once more. With his clothes in a sack strapped over his shoulder, Spidey made his way to the DB. He was shocked to see a bunch of kids gathered around some costumed man at a construction site. Spider-Man came down to their level and tried to draw the kids away from him.

"So, you gather 'round a guy and don't take him to a hospital?"

"He ain't hurt, just K-Oed."

Peter saw one kid reach behind him for a bat, obviously one of those "vigilantes are bringing down society" types. In his mind, Spider-Man couldn't help but think 'Ol Mayor Jonah has reached even the youngest of hearts! Spider-Man webbed the unconscious man in the black costume to him, securing the stranger a little privacy.

"You really think that's a good idea?" he asked referring to the kid with the bat.

The group looked at each other, and then ran back to an arcade or where ever kids go when they skip school. Spider-Man took the stranger and propped him against a sheet of metal. The guy began to stir, moaning in pain. Peter could just hear him utter to himself, "What a trip…"
