A clever reader had requested this match up not too long ago. I think it's fitting as I recently posted an Injustice Multiverse Timeline fic that includes the events of DBD and other slasher properties into it. So be sure to give that a check out once you're done here.
With that said, let's begin the chapter.
Presumed dead after his enctouner with Killer Croc, Doctor Crane was left to rot in the trenches of Arkham Asylum. Lurking around the prison of Black Gate at night and the halls of the psychiatric ward, subjecting captive patients and unsuspecting guards to his various serums. The Scarecrow was working on something stronger with his chemicals. Something that wouldn't only enduce fear but bring it to life.
Aside from Batman, however, there was only one other who believed The Scarecrow was still alive. To confirm his suspicion, Tim Drake snuck his way into the confines of Arkham Asylum, unaware of the horrors that lied in wait for him and several of the escaped patients. Now trapped in an endless loop of a corridor, The boy wonder seeks away out before he finds the truth he was looking for.
Arkham Asylum, or the shadow of its trueself at least. Cells in the halls were flung open, mostly. Others, the bars were bent and pushed outward, as if something was giving it their all to get out. Some of these cells contained lockers to hide in or could be closed to trap others in for a short while before the constant power surges in the building would open the doors. In the center of it all, an operation room. And above that, waiting on the second floor and only accessible through this room, the security monitor room. A place where anyone can observe where another is in the eight hallways. Some monitors would fritz out, as a result of the flux in the power, blinding the observe to some rooms until the next surge. But it all served The Scarecrow well enough.
Two of his four patients had been overdosed by now, leaving only two more. One being the Boy Wonder himself. Crane stalked the corridors he last saw them on over the monitor, his chems hazing out of the containers he carried on his back. This created a cloud of his fear gas around him, making him dangerous to be around but slowing his movement as well. Crane caught one of the survivors, the third before Tim Drake, fleeing down the other end of the hall. To compensate for is lack of speed, Crane activated his special attribute.
Tossing a gas bomb to the survivors area, The Scarecrow gas took effect. Causing its victim to see a green haze fill the environment and copies of The Scarecrow's image as each one approaches them. This attribute is short lived but effective in turning the victims around and enducing panic, causing them to stumble around as they avoid the copies while trying to flee from the real Scarecrow. This survivor was not so lucky though.
Crane caught up to the survivor and plunged his syringe hand into their chest, allowing them to flee a bit as he cleans his needles. The crippled survivor could not get far as they were reduced to only limping now. Crane stuck them once more while in pursuit and brought the survivor to the floor. Defensless, they could only await death.
Scarecrow flipped the survivor over and rested a knee on their chest, pinning them to the floor. He then reached over his shoulder to one of his chemtanks on his back and pulled out an laughing gas-mask and hose attached to it, forcing it onto the victims face as the hose fills their breathing apparatus with the fear toxin. Whether it was the fear of whatever it was the survivor saw in their head or an overdoes of the chemicals that killed them, we may never know. But that meant, it was only Robin left now.
The Scarecrow would relish this moment, bringing the young ward of the man he blames for his mauling at the hands, er, claws of Killer Croc to his knees in fear. He roamed the halls of the Asylum, a place he knew all too well by now, in search for the boy wonder. But that's where being trained by The Batman, and surpassing him in some fields even, pays off.
Red Robin was clever, and found the escape hatch on one of the unguarded monitors in the security room. The only catch, it was in the hall that Scarecrow was patroling. Tim knew Crane would be back to the monitor room soon enough though, and that's where his special attribute would come in handy. Tim took out some of the detonating spray foam his utility belt carried. The spray could only be used in one location at a time, meaning Drake could only lay down one trap and would have to set that one off before making another somewher else. Luckily, he needed it in only one place as there was only the single doorway into the room. On the ground, infront of the door, he would lay his trap. Making an "R" on the ground so that the moment Scarecrow would step in, he would be flung back and hit the ground in a dazed state, giving Robin time to dash past him and out the hatch to get reinforcements.
His time under The Entities beck and call had taught the maddened doctor much about the meaning of fear. Countless victims, subjugated to his tests and expiremental serums. The Scarecrow found what he had needed to bring Gotham to its knees. He found what he needed to bring an end to The Batman. (To Be Continued in Arkham Knight)
