Gotham City, Date Unknown (Sorry, nobody gives a realistic date for the series :P)

Killer Croc groaned as he got up, shaking his head violently as he tried to make sense of his surroundings.

The familiar smells and sounds of a sewer permeated his mind, putting him at ease as he slowly opened his eyes.

Looking around, he saw a couch with a beaten pillow and blanket, presumably a make shift bed. A table, two chairs, a refrigerator and some form of beat-up dresser filled up the immediate area, with the far end open with a sudden drop.

Slowly getting up, he started to walk over to the edge. Looking down, he saw a large pool of sewer water and underneath was a sewage pipe, large enough that he could easily fit through.

Turning around he then saw the posters and newspaper clippings. He recoiled, taking a step away and almost falling off into the water below before regaining his footing.

Pictures of a tall man, green, scaly skin, yellow, reptilian eyes, and sharp clawed hands and feet. It was none other than the being he had passed in the portal.

Croc vigorously shook his head, not being able to believe what he was seeing. If what was before his eyes were true, then he may have…no, it's impossible, there couldn't possibly be…multiple versions of himself, different universes of himself.

Looking up he knew for a fact he would have to see things for himself, or else he would possibly lose whatever sanity he had left.

Jumping into the sewer below, he slipped into the sewage drain and headed up.

Slowly pushing the manhole cover aside, he reluctantly peeked out into the alleyway. Somewhat familiar, he knew for a fact that he couldn't possibly be in the future if the buildings on either side were made of brick and smoke permeated the sky above.

Looking about to make sure nobody was in the immediate vicinity, he pulled himself out of his manhole.

Finding a large amount of dirty and discarded clothes about, he pulled out an oversized trench coat with stains on it and a beat-up fedora to hide his identity for the time being. Wrapping his tail awkwardly around his waist, he walked out of the alleyway and into the street.

The sight before him amazed him. Mobs of people flocked the street's, all of them seeming to have dressed in styles ranging from the 30's to the early 80's, though from the looks of it the 30's and 40's were dominant over all else, the massive numbers of coats, fedora's, and knee-length dresses attesting to the fact over anything else.

Cars' from the 30's to the 50's rolled down the street, and a train shot by above him. Finally, a large blimp flew overhead, with a few small, primitive helicopters with police imprinted on their fuselage catching his attention.

Looking around, he realized that chances were this other universe he was in was back in time.

But the largest shocker was picking up a fallen newspaper that had fallen by him. Picking it up, it boldly read in gothic lettering Gotham Gazette, and the front headline said in all capitals "BATMAN DEFEAT'S PENGUIN, THIRD TIME THIS YEAR"

He felt the paper slip through his fingers, unable to comprehend that he wasn't just in a separate universe; he was in a separate Gotham.

He took a couple paces back into the alleyway before slumping against the brick wall, his mind going a thousand directions.

His enemy was still at work in Gotham, which no doubt meant that the other villains were at work as well. All of them; Poison Ivy, Mr. Freeze, Bane, Penguin, and Joker. The whole lot of them were most likely about in this godforsaken city.

Then another thought jolted him. Then if the other person he had passed had been the Killer Croc from this universe, did that mean they had switched places? Had he essentially replaced this universe's version of himself?

He clutched his head as he tried to comprehend what was happening. It was too much to take in, too much to handle at once. Different universe, different time, but the same people…

It took him quite a few hours to stop his head from spinning, but he finally settled down to try and think straight. And then it hit him.

Everything was different. Which meant that nobody knew of his plans. Maybe…he could start over. Start anew. Maybe even try and go straight, even if the chances of that were still slim.

Getting up, he pondered his options. Would he just become a recluse, and stay underground for his life? Or maybe get hired for a somewhat legitimate job? A guard? A bouncer, maybe? He was certain someone would most likely find a use for him as hired muscle outside of criminal circles.

But for now he knew that he would have to wait. He would have to explore this city, come to understand it, because even while it was Gotham, it was a very different, older Gotham, one with different rules, different laws. Something that he knew he would have to know and understand before doing anything.

But he would learn, and as one of the oldest mantras drilled into him came into his mind, he knew what he would have to do; Adapt, Improvise, and Overcome.
