Hey remember when I said I was going to try and finish this before Arkham Origins came out? I KNOW! HA! I've been playing the game and now I've got to completely change my idea for the third fanfic of the series! Thanks for the awesome reviews guys! This chapter is a bit shorter because I really wanted to get something out for you for the release of the game.

Enjoy!

The sewer corridor seemed to have got longer when she took her first steps into Killer Croc's lair. A foul smell of dirty water and rotting meat got trapped under nostrils and it stuck in the back of her throat, her stomach threatened her with sickness but she waited a few moments to let it settle.

The grates stared at her in such a way it was like they were laughing at her, they were saying 'scaredy cat!' in their silent wooden voices. Filly was sure that she was finally going mad. Bubbling up all the courage she could muster, she pushed her fear aside and lifted her foot and placed it as gently and quietly on to the crate.

Once both feet were on the first grate, it sunk only slightly but Filly felt like a sack of bricks on top of them. The green lights illuminated the walls, the thick gunk which looked like a mix between mucus, soot and other things she tried not to think about.

She got to the first plant rather easily with no fuss; the batarang easily tore through the plant, it dropped with a squishy thud onto the crate then Filly began to collect the spores. In her pocket there were ten batarangs left, she prayed that she wouldn't run out. The only thing she didn't have was the line launcher which didn't really matter as she was sure she'd be able to jump the distance.

Finding a vile had been easy, the doctors examined him so often they had plenty of viles with his blood, saliva, scales and so forth, there were plenty of clean ones but no toppers. In the end she grabbed a handful of paper towels, ripped them up and twisted them tightly into the top, Filly hoped that is would keep everything inside. She was done collecting from the first plant and readied herself for Croc.

"Why am I doing this? I was almost killed by a crazy and Croc is about two hundred times more dangerous and monstrous." Oh come on Filly is your chance to show you can be as strong, brave and as badass at Robin and Batgirl! This is the mission that you fail badly at but come on, don#t feel scared be determined, you can win this, "Yeah...I can do it..."

She began to break down mentally the path in her head. In the game it always seemed long as you'd end up going the wrong way or Croc would begin destroying the crates and you'd end up having to double back. Then he'd pop up from under the water and come trudging towards you in his sinister pace. The thought made her stomach boil back to life with sickness; not being able to stop her stomach this time she threw up into the remains of the plant, her eyes shut tight and her nose crinkled up as if to block out the smell.

Croc had surely already caught her scent, she imagined that she smelled a lot different from Batman, he'd be so pleased that he would be getting a 'easy meal'.

The waters began to ripple wickedly, Filly heard croaks and snarls then the animal roared, "You dare come down to my sewer!? You won't find the big bad wolf down here...here you'll find something much more worse!"

Filly could practically here the music in her head, the sharp violins and horrific drums; Croc unleashed himself from the water and charged towards her. She wished her fears would release her but her hand wouldn't let the batarang go! Every second he got closer Filly urged her power to slow time down; it worked but it was already beginning to crack underneath Killer Croc's strength. The batarang locked on to the collar, it flew from her hand and hit Croc; time returned to its normal pace and Croc clutched his collar and fell into the water.

The crates swayed from side to side then quickly settled; there was a taste of accomplishment on her lips, she couldn't believe that she survived the first of the Croc confrontations. Adrenaline was tingling in her fingertips she was itching to run on the crates and give it all she had, but she knew that would be a stupid idea.

Crouching down she took quick quiet steps, corner after corner she finally found another plant and collected from it. Croc hadn't made another appearance yet and it started to worry her; the sooner she got the spores the better, she quickened her pace a little more but it was a bad move.

"I've got your scent girl" came a growl.

Like before, Croc burst out from the water and came towards her but Filly was ready. The batarang did its job and Croc fell back into the water. She was sure that there were only two more plants to find; after crossing more crates the water rumbled and from behind the wooden platforms were destroyed. A bead of sweat rolled down her face and splashed on the wood, Filly managed to get to the third plant without a hitch but she a frightened shiver ran up and down her spine, she knew that this was going to be tricky.

In front of her was a wall and beyond it was the next plant and any moment now Croc would come crashing down. She heard a loud splash and the animals roar echoed; shaking more than ever with the batarang in her sweaty palm, the wall came down and Croc looked incredibly close. Unsure if the batarang had locked on she threw it and luckily it hit his collar but it wasn't as effective as before. It sparked and zapped Croc, he ignored it but at the last second the jolt of electricity struck him again and he fell just a few inches away, but Croc lashed out, his body was under water but his large scale talons clawed at the crate Filly was on. Panicking Filly grab another batarang and stabbed in three times into his hand, after the third he brought back his hands and settled back underneath the small waves.

Her heart battered against her ribcage and she could hear its pounding in her ears. The fourth plant was in her sight and she wasted no time in collecting the final spores. The test tube was filled to the top then secured and place safety in her pocket. She stood straight and stared at the path ahead of her, Filly couldn't believe she had survived this far and she had no intention of failing now.

The journey back was going to be quick, she arrived at the gap and managed to jump across to the other side, when Batman used the line launcher Croc would reach out and try to grab him but he made no attempt to reach her. But she knew that he was trying to scare her and it was working only slightly; jumping over gates and going past corners with no sign of Croc Filly figured out what he was waiting for. In the final hurdle of Croc's sewers, the camera would change and Batman would have to run while the crates turned into splinters behind him.

In three...two...one.

The water bubbled and the crate was gone, Filly smiled to herself, she was thankful that she had her running abilities there would be no way he would catch her here. In a flash she was at the other end and she laughed as she took a moment to watch the crates explode.

Approaching the gate Batman was just on the other side fiddling about with his cowl, he heard her footsteps followed by a blood curdling roar right behind Filly. Croc unleashed himself from the water and the gate slammed shut trapping her in the monsters den. The Dark Knight took hold of his explosive gel and threw through a gap in the gate, a small canister filled with gel which looked like a grenade landed by her feet; bending down she picked it up and screwed off the top, her breathing heavy and throat drying up in terror.

"Take two steps forward and empty it on to the ground, quickly!"

Croc was approaching fast but Filly's power struck out and bought her a few more seconds. The gel was emptied out onto the concrete and Croc had broken through Filly's power. He was getting closer. Oh shit. And closer. I don't want to die here! And closer.

"Batman now!"

She curled herself into a ball and shut her eyes so tight as if she was trying to punch tears out of her eyes. There was a loud explosion and the shouts from Croc falling into complete darkness, the gate was pulled up and Filly toppled over and sprawled her limbs out willing her shaking bones to steady.

"You could have gotten yourself killed," she lifted her heavy head and looked up at him; the Dark Knight's eyes looked furious and made Filly feel so small; he sighed and held out his hand, "Give me the spores"

Slowly moving on to her knees she pulled out the test tube filled with spores, she was surprised that it was still in one piece. Handing it over he remembered the pace of the game and she couldn't stop herself from asking, "What happened to Scarecrow?"

"He was pushed into the water by Ivy's vines. I want you to stay here for at least ten minutes to let yourself calm down then I want you to head back up to the surface and go to the front of Intensive Treatment, around the corner there is-"

"I know-" she interrupted him.

He gave her a small nod, took out his line launcher and headed to the exit. Once Batman had gone Filly scurried over to the water and lightly touched it with her fingertips, she had to find out what happened to Scarecrow. Images flashed in her mind, Scarecrow holding his fear powder over the waters then out of nowhere he was pushed off his feet by a vine and the bag of fear landed with a innocent thud on the edge. She couldn't get any more clear images of what happened next so he lifted her hand away from the water then something came out from the water and tried to pull her in.

Crying out in fury Filly grabbed on to the shoulders of her attacker and used all her strength to pull them out and knock them against the wall. Her eyes focused on the attacker and it was just who she wanted to see, Jonathan Crane scurrying to his feet holding on to the wall for support, half of his gas mask was missing, he took a swing at her which she easily dodged. After suriving Croc she wasn't going to take shit from the skinny, now powerless villain.

Filly reached out and grabbed his neck and threw him as hard as she could on the ground, he groaned and Filly was ready to punch him but he held up his hands in surrender and she found it rather amusing.

"I heard you scream, it was beautiful," Filly rolled her eyes, "What was your nightmare about?" he asked.

She wasn't exactly in the mood for this conversation but she humoured him, "It wasn't a nightmare. I screamed because I woke up in here."

He giggled, "The asylum is finally taking it's toll on you I see."

Grunting at him she crouched down in front of him and got into his face, if someone had seen them from a distance it would of looked like she was going in for a kiss, "Listen here you little worm, you need to get out of the asylum, I don't care where you go. You have failed in taking down the Batman, your time is up so I wouldn't bother going after him."

"The great Scarecrow doesn't take orders from little girls!"

Jeez what is with the little girl treatment?!

"Oohh the 'great Scarecrow', you are nothing without your mask. You better not be here when I get back Crane or I will feed you too the big bad Croc."

Before he could snap back with a remark she knocked him out and stood away from the master of fear. Before leaving she jumped over to wear he had dropped his fear poison, she wonder why Batman hadn't dealt with it. She picked it up and pushed it into the deep corners of her pocket. Heading back up she decided she would pay a visit to the Joker before meeting with Batman.

"Filly my dear! I was beginning to wonder where you were."

"Yeah...I had a date with a temper tantrum lizard."

He giggled, "Well I've been thinking, you need a new name."

She grew a little red, "I...I have thought about a proper...superhero name."

"Ooooohhhhhh please share! I'd love to hear!" She wasn't sure if he was faking the enthusiasm but she went along with it.

"Warmblood"

"Ha ha! Seriously?! Where you'd get that idea?!" he laughed.

Filly bit her lip and saved back a snarky reply, "It's a breed of horse, a couple of my ideas are."

"Hmm what else?"

"Sorraia?"

Joker pulled a face then gave her a thumbs down.

"Mallorquin?"

"Yuck! Is that even an english word?! Nope, don't like it."

She sighed and told him her final name idea, "Shadowmare"

He was silent for a few moments, "Hmmm...Shadowmare...I like it! It's dark and mysterious, a title worthy of an Arkham gal," Filly gave a small smile, "However, you need to earn the name my dear so scoot along, I'll be watching."

Being called 'Arkham Gal'gave her butterflies in her stomach, she was pleased that the Joker liked the name but she decided to keep it quiet from Batman. He was standing waiting for her, she rushed to his side and he explained the next move. The Botanical Gardens.

They rushed over there in silence, Filly couldn't believe that the end was almost in sight, time was flying past in the madhouse and it was so hard keeping up.

"Are you ready?" the Batman asked when they reached the doors of the gardens. Filly nodded and followed Batman through. The first thing that hit her was the smell and the blinding shades of green, "What do we have here? You brought help Batman?" Poison Ivy's voice sounded from the walls. Vines wrapped around Filly's arms and legs, she was thrown off her feet and dragged into the cracks of the wall. Batman threw several batarangs but none managed to tare the vines apart. "You better hurry Batman, you wouldn't want your little sidekick to fall into my charms."

Filly groaned as her body landed with a thud on the ground, she felt the last of the vines leave her skin then she got on to her hands and knees. As her eyes adjusted to the light Filly stared at the concrete floor but two long, slender green legs crossed her field of vision; slowly looking up Filly locked eyes with Poison Ivy.

Sorry that the ending is a bit short but I really wanted to get this out, its been nagging the back of my mind for ages! So please review, its always amazing to hear from you guys :D
