"So far when it came to Casey Jones, there was only two things he understood in the world. One, was that every city as well small block had it's problems as well would lead to innocents getting hurt along go missing. Two, that there had to be people to handle these matters as well make sure it stopped for good. However it never come, in which he would have to come in as well handle the matter. He was pretty good at it, as well met a strange array of individuals who helped people. In which they themselves aided him in protecting the city he cares for, as well it came to Slash. In which the large aggressive turtle was the one 'individual' he would be cautious of. Though during the month's that passed, it was a surprise to see him along with that of the so called 'Batgirl' from the internet. In which there had to be a explanation behind this, since the pair themselves wanted to know something from him as well."

Underneath New York City

When the base of the purple dragon's came down, along of making a building go down in smoke. Casey had to bring both Slash as well Batgirl to a place where the cops or anyone else couldn't find them. None other than a lair of their own, which was New York City's sewers, right now the three were walking pass the water. While Casey and Slash ignored the rather horrid smell, Batgirl was unable to get used to the sewer water passing them.

"Are you sure this is a safe place to be? I heard rumors about alligators being here."

Batgirl spoke out bringing up a old New York rumor about how people would flush down baby alligators, Casey chuckled at the mention seeing how that it was somewhat half true.

"Don't worry, Leatherhead hasn't been swimming up here. He's down in the sewers under Brooklyn."

The hockey masked vigilante answering Batgirl's question which had the red head a bit surprised, the three continued to walk until they reach to the end of the walkway. As well noticed that of some pipes that were connected to the surface, Casey went to the side as well pulled a rusty type pipe. Which sure enough, made the rest steam making them move back. To which opened up a entrance, inside Batgirl was hearing some noises as well that of arcade sounds.

"No way."

She spoke sounding amazed as she head inside, soon enough she was in a that of a secret lair. Around her were several rooms, a few arcade machines. Plus a monitor which showed the area of the city plus the layout of the base.

"It's like the hall of justice, except it's low maintenance. Plus underground, as well. Smell's like pizza?"

The bat teen asked along of looking around the place, in which it was a mixture of a crime fighter's base along that of a hangout for teenagers. Slash, walked inside to look around the place as he seemed to remember it.

"Friend's home."

Slash spoke out as well touching the railings, along of looking at the place. Casey saw how the two were reacting to this moment, in there was a lot of explaining to go around.

"Ok, so where exactly should we start off? Like how did a college kid like you found Slash?"

Casey starting off on how that she stumbled upon the large turtle, along of how they came to his city. Batgirl, nodded as well found a chair in which she seats down looking at the hockey masked vigilante, to where he did the same thing as well gave her his full attention.

"Well, I'm actually in a university. Along how that I found Slash after he was being used by one of my home's greatest villains. The Riddler, he forced Slash to kidnap some people who we're surviving New Gotham."

She started off of how in the past months, Casey heard about a place called 'Gotham City' being taken over by some criminals. Along it being quarantined off from the rest of the country in which they had to survive on their own, it was long as well vigorous. However, they managed to handle it and get it back into normal. Casey, was stun how the teen manages to handle the life of a crime fighter.

"Ok, so flying bugs I understand. People wearing spandex and capes fine, but. The foot fighting super villains?"

Asking her about how Batgirl brought up a detailed part of how she along with Slash and Robin, battled the Shredder as well the foot clan. The girl nodded sadly as well remembering it, if it was different. She probably be dead if Harley and the others didn't wear him down.

"It happened so fast, one minute I was geeking out when Robin talk about how he was raised by the League of Shadows. To then teleported by a thousand year old witch to fight a ninja master. But after all that craziness, as well messed up crap. I want to know, how did Slash ended up in the sewers beaten and hurt."

Batgirl getting right to the point, in which Casey. Seeing the look in her eye about what happened to the mutant turtle. In which Slash, was walking over to the beds of the ninja turtles as well not seeing them. From the look on Casey's face, Barbra knew it didn't look good seeing how she was about to get her answer.

"Well, it started off like any other night in New York. With a fight."

Casey beginning his story about how Slash ended up in the sewers, he remembered it like if it was yesterday. He got a call from Donny about a fight happening in TCRI, a company that is involved in many scientific research as well considered one of the best labs in the world.

"Apparently old shred head along with Krang was doing something. While the boys could handle themselves, they knew it be best to bring old Casey Jones in the mix."

Smiling at the thought of how during the mission, the turtles needed some assistance. Not wasting time he got his gear as well headed out, in which when he arrived at the sight of the fight. It looked like a turf war being settled in the streets.

"You wouldn't believe it when I saw a all out brawl. Foot ninjas being clobbered. Mutants flying about, everyone was bashing. Hell even the old master rat Splinter was there kicking ass and taking names."

Smiling at how it was fun, Batgirl got a bit nervous of how he enjoyed the fight. Though as they talked, Slash's head lifted up when he heard the sensei's name as well father of the turtles.

"Splinter?"

Slash spoke out as the large turtle rushed to that of the small room in which the rat would be in. Being cautious as well seeing the screen door, the turtle opened it as well saw no one. The padded dojo where he and the turtles would train, was empty. The two humans looked at Slash, who only looked sadden by the sight of the people he seemed to know gone.

"Yeah, now where getting into the shitty part of the story kids."

Casey continuing his tale, along how when Casey got into the fight joining the turtles as well their master. Something apparently happen, during the tussle. They were in a room which involved a experiment happening. While he was clobbering that of some foot ninjas, the human saw Krang turning on the device.

"Apparently the turtles were stopping Krang from bringing in some of his folks to mess with New York. So the turtles stopped him, however. The machine went hay wired and blew up. Killed some ninjas, sent Slash flying through the building and me? Not so banged up, but knew I had to get out."

Bringing up a rather sad like ending, that left his friends being taken away. Left alone as well had no choice but to leave, the last thing he remembered was Shredder yelling in anger as well forcing to retreat.

"I went to check out Slash and only saw a empty hole. Looked half of the sewers for the lug head. Couldn't find him, but from how now I see him. He's ok and healthy again, for a spiked mutant turtle."

He smiled at how Slash looked much better, however. The large turtle merely was upset as well gripping his fist feeling like his anger was taking over. Both Casey and Batgirl got a bit worried for how the large spiked turtle was about to roar.

"Slash? You need to calm down. They may not be dead."

Batgirl doing her best to calm him down, however this time it wasn't going help out. Casey, slowly went to his hockey bag in which he would have to whack some sense into him. However, before the two would face in that of a fight. They heard the secret entrance door open, they looked seeing someone entering.

"Casey! The next time you want to try and start trouble with the Purple dragons you should consider the fact of calling ahead! People think that it might be..."

A woman shouted out both angry as well coming threw the door, the three soon saw a adult woman. She had orange hair, green eyes as well a yellow shirt on. From what she saw, it looked like quite the sight from how Casey was talking to a costume girl and Slash. The large turtle, noticed her as well turned his head in a curious manner.

"Smart lady."

Slash spoke out as well feeling his anger of seeing his friends and Splinter going away, the woman herself. Walked over to see him as it was a surprise seeing Slash alright and back here.

"Your alive? How did you..."

Before she could ask, Slash merely hugged her like if she was a long lost friend. The woman noticed how he hugged her, as well tapped on his shoulder to ease up as well hugs him thinking he was taken out during the fight.

"Batgirl, meet the turtles or rather most mutant's best friend as well smartest red head I've met. April O'Neil. April, this is. Batgirl."

Casey doing the introductions in which April got a bit shocked at hearing the word 'Bat'. Slash, putting her down as April walks over to meet her. Along how Batgirl, looked at her in which it looked like she was seeing her future self.

"You mean like 'Batman'? The Batman? I tried to do a story on him but most people didn't believe me."

April expressing her interest in the Bat, along how it made Barbara stun that this city hasn't heard about Batman. Gotham or maybe possibly the Justice League, she nodded about how Batman did exist as well she was considered a 'hero in training'.

"Well he is a anti social person, along how that he's had his hands full with villains. As well these new incidents involving mutants."

Batgirl responding back which had both Casey and April concern, mutants in Gotham? April decided to head to the monitor where she typed in some buttons. Whatever she said, got both April and Casey riled up in which Batgirl didn't understand.

"Then I guess you found the source of the problems, because in this city. Half of it belongs to humans, the rest. Mutants."

Casey informing Batgirl at this is the place where mutants come from, in which April brought up some photos. To Barbara's surprise, the city had has it's own variety of mutants. Different ones, let alone of how they were all animals. There was even one that had Slash in it, which showed him fighting against the same turtles he called friends.

"Most of them are friends. Such as the turtles, and master Splinter. The others? Not so much, most of them are aligned with the Foot. Though lately we noticed them them showing themselves. After the TCRI fight, they just kept in the shadows."

April giving some enlightenment to Batgirl of how mutants lived here, in which most of them seemed friendly. Though what caught her eyes was two that worked with Harley and her gang of villains. Pointing at the screen it showed both Bebop and Rocksteady at that of a Sushi place drinking as well hanging out with some girls as it was a old photo. Along another, in which it was Karai who was leading the two in a attack

"I know those two, there with a criminal I know back at Gotham. Bebop and Rocksteady, as well that woman. All three of them are in Gotham."

Pointing out those three being seen in Gotham, the two New Yorkers looked alarmed at how they hadn't been seen in months let alone a year. Batgirl could tell there were much more to the trio seeing how if they came here, it had to be bad news.

"Those two dumb ass's were with the foot. Heard they got kicked out, but I didn't expect Karai. Half the times that ninja lady leads them, though after the turtles disappeared. She left, is Gotham the place to hang out at?"

Casey asking Slash as well describing how here, Karai would be by the Shredder and Foot's side. Slash, nodding of how things in Gotham was rather fun than in New York. All in the while, Batgirl was on the side still taking it in. This city had gang trouble, mutants as well a company that deals with scientific research. Still thinking, Slash looked at Casey needing to know one thing.

"Where, are friends?"

Slash asking Casey about where the turtles might be, in which he didn't know. Let alone of that during the explosion the turtles didn't come back, Slash lowered his head at how he thought they were suppose to be here. Though as they were feeling sorry for their mutant friend, a alarm went off which got the four's attention. Apparently Hun was still active, as well had that of some of new weapons and was right now doing some damage on another gang's turf.

"Are those exploding penguins?"

April asked confused in which Hun was using several weapons that we're clearly out of town. Batgirl, walked over as well nodded seeing how that Hun was tearing apart the street.

"I should go and handle it. I know those weapons and how to break them."

Batgirl insisting on going after him since she's study up on Gotham's villains tech as well gadgets, however. The two girls head a sudden thump, which came from a metal baseball bat that Casey Jones was holding along ready to use it as well having his mask on.

"And this is Casey Jones city. And whatever Hun is doing, I handle. Though, I don't mind a few playmates."

He spoke to her as well Slash, in which the mutant turtle looked ready for another fight at Hun. On the side, April could tell they be going after him. To which she grabs that of a headset as well begins to work on the computer monitor.

"I can make sure the people stay away from the fight as well keep cars away. I know a thing about Donnie's tech, as well being connected to the traffic lights. Just don't make a mess and keep it quiet."

April explaining how that she could hook up to the city's electricity as well make sure to keep innocents away from the street fight happening. Barbara, found it fascinating of how she could operate the technology in the city from this lair alone. She wanted to ask how it was possible, though both Casey and Slash rushed out to try and take on Hun.

"Dang it, alright I'll keep a eye on them. Also find out if anything else happen with TCRI."

Batgirl telling April if there was a aftermath when the building was attacked, let alone of if the technology and resources was taken. The red head nodded as well got to work quick, as well surprised at how she could see at least one ninja turtle. It's been months since they've been gone, and now one comes up and is with a costume girl. April defiantly missed this type of atmosphere as she got to work on making sure Hun didn't attract a crowd.

Night time-China Town

Within the part where it was considered 'China' to New York due to it's culture and environment. It was also a good place for a gang that was hiding from the police, which was the Ghost Boys. Who were right now in a fire fight with that of Hun, who was using some new weapons that made him rather unstoppable. Most of them were speaking Chinese as well asking for reinforcements, though they couldn't due to Hun throwing that of explosive ice grenades at them.

"Oh I'm sorry! He won't be making that phone call any time soon!"

Hun shouted as well enjoying his own fire power, along of how he was armed to the teeth. He had that of several freeze grenades, penguin's armored umbrella that was both bullet proof and a machine gun and Riddler's cane which he modified it to a whip. The white suited men were moving back at how the large man was taking them out.

"I take Ghost boys territory under name of both the purple dragons, and the foot. Any objections?"

Asking them seeing how most of them were insulting him in their native language, to which Hun merely sighs at how annoying they were being. Charging up the grenades, he throws several at them. The men tried to move back as well avoid the ice blast, however. They were stopped by flying shurikens. Exploding into white smoke, Hun was blinded by it. Along soon heard some grunting let alone people being beaten up.

"Hey! These asshole's are mind to hurt!"

He shouted as he continued to shoot around the side to see if he hears a body drop. Though instead of people getting hurt, there was some groaning. To which the people he tried to kill was tied up, was hanging upside down a light pole along of away from Hun. The large man looked around, trying to see who did it.

"You should know little bat, this is my town! I run.."

Before he could call out on seeing that Batgirl was here, it was interrupted by that of a hockey puck which flew right into his head. Hun, moved back feeling the sting as well soon noticed that of a fist coming his way. Which was Slash, the turtle sent him flying onto the ground making the concrete crack. The large man shook his head as saw in front of him, it was Slash along of Casey Jones plus Batgirl standing by his side.

"No, we protect town and city."

Slash spoke as well holding that of a spiked mace in which he was ready for a fight. Hun, merely chuckled seeing how this seemed like a uneven fight let alone how he was getting tired of getting beaten by them. Standing up, Hun decided he had enough getting beaten by masked people.

"You know, I never understood the fetish of having a mask or messed up super power. That was until I reached Gotham, and my boys snag me something that really got my interest."

Hun responding to them as he dropped all the weapons he had on him, in which he showed something that was attached to his right wrist and neck. It was a red pipe like device connected to a glove Hun had on, while Casey didn't understand it as well Slash. Batgirl, looked scared at how Hun was wielding one of Bane's venom gauntlets he gave to his luchadores.

"Wait don't do it!"

She cried out warning Hun that the usage of Venom was dangerous to someone who's trying it for the first time. Hun, merely smiled as well gripped his fist. Soon enough he felt his body changing. Hun's eyes widen along of feeling his whole body growing. He stretched out his clothes as well having his top ripped off. Showing off the purple dragon symbol on him, Hun had gone full Bane as well let out a angered yell.

"Damn, Hun just went from big to freaking huge."

Casey stated as he pulled out both his hockey stick and bat, in which the three had to be ready. Hun, looking angry soon charged at them. Going right for Slash, he delivered a quick strike to his shell making Slash gasp a bit at how strong he was. Casey, spinning his weapons went up and struck his face.

"Goongala!"

He cried out hitting Hun in the face, though at the second strike. He noticed his metal bat bended, it shocked him as well saw how Hun was smiling. Grabbing him by the neck, he hurled Casey threw a window crashing inside. Slash, let out a roar as well whacked against Hun. While it did give Hun a black and blue. It still didn't take him down.

"I'm going rip off that shell and wax you with my car."

Threatening the turtle as he did several punches to Slash's face along sending him threw a brick wall, seeing this. Batgirl looked at the venom out criminal, as Hun merely smiled at her.

"Smile all you want, because this is different from Bane's. Can't pull out."

Hun telling her seeing how Bane's tubes were easy to pull out, however these were new, in which they stayed attached. Not responding, Batgirl kept back as well saw Hun lunged at her. Flipping right over him, she made sure to keep her distance as well think about how to handle this.

"Ok think, Bane sometimes forgot to reinforce his tubes. Hun didn't, but they still are stuck on him. So even if I beat him he still has strength, and might possibly break me. How can I."

Thinking about if she could get the venom away from Hun, he still fight them. Though as Barbara pondered at the idea, she noticed some telephone lines above her. As well them being off, which April had done in order to keep people away from. A idea came into her head, looking to Casey as well Slash coming out she needed their help.

"Guys! I need you to bring down the telephone poles on me and Hun!"

Calling out to them to do some damage, Casey merely smiled at the thought of some damage as he pulled out a hammer. Slash not understanding does so, while Batgirl distracted the venom crazed Hun. Both Casey and Slash were hitting the poles, continuing to avoid Hun's attacks. The purple dragon noticed the poles coming on him.

"Batgirl!"

Slash shouted as he rushed over and picked her up, the three moved away seeing the pole lights crashing onto Hun. In which the wires got him tangled up, this left Hun angered as he tried to get them off him.

"One of the most foremost rules of electricity? Never get it wet."

She stated as she pulled out a batarang from her belt, throwing it at Hun's tubes. The venom juice came right off, along of spraying across the electricity lines. Hun, felt his newfound strength going away as well reverting back to his normal self.

"Even without that shit, I'll still rip you apart."

Huffing at how much it took out from him as Hun saw the three looking at him, Casey. Hearing Batgirl whisper something in his ear, nods as well texts April a important message. Before Hun could get out, the lines soon turned on as well electrocuted him. The three moved back seeing Hun fry, as well that it didn't even kill him. Hun, was still standing but looked like he was about to keel over. Batgirl, gripped her hand as well slowly walked over to him.

"Also Hun, I want you to send this message to the people in jail. I'm not just a little bat. I am hope, I am the night. I, am, Batgirl!"

Telling Hun his name in which she delivered a strong right punch which knocked him out cold, along making him pass out which he collapsed onto the ground. Now beaten, the two males looked at how Batgirl stood her ground and knocked him out.

"Damn, that sound pretty awesome. Though I'd suggest using a hockey stick."

Casey suggested which Barbara merely laughed, along of how it seemed like a win for them. They had the leader of the purple dragons as well several ghost boy criminals, all in all it was a good win.

Later

On top of a roof, Batgirl and the others were talking about what April was able to pull up from the news about the TCRI explosion. Apparently after the attack, the people inside had to relocate somewhere that they new their inventions could be safe. In which April was showing the information where the tech was taken.

"Oh give me a break."

Batgirl spoke out seeing how that the technology had been taken to a lab as well company that could be well trusted as well could rival their own technology and scientific inventions. Wayne Enterprises.

"Great, so a playboy has the tech to find out where those shell heads are."

Casey spoke seeing that Batgirl would need to travel back to Gotham and head into Wayne enterprises. Slash, lowered his head seeing how that they would be continuing this adventure. The caped girl noticed her large shell friend upset as well tapping his arm.

"You could stay here if you like. I mean it is your home, and I'll find the turtles soon."

Batgirl giving Slash a chance to remain in New York since it was his home, it was tough choice. In which Slash looked at Casey and April who smiled at him, in which he knew them well. Though for Barbara, she understood him as well helped him when he was used by Riddler.

"Find friends together, then go home. Cause people do crime?"

The large turtle stating he would still stay with her until they find the four ninja turtles and master splinter. In which Batgirl nodded at the last part seeing how she understood the reference.

"They'll be bashed."

She finished the saying as she laughed a bit, in which it was going be a long way back to Gotham City. Seeing how it might be a while, she suggested they all took a selfie together. They all got in close to take a photo of them being together, as well something Slash could remember when he felt home sick. Though now, it was time to head back to Gotham and head straight for Wayne Enterprise, and see what they are doing with TCRI technology.
