Here we are with chapter 11 for the sequel of this story, despite it yes being chapter 39. So, first of all thanks again guys for the reviews from the last chapter. I appreciate it and also yeah sorry I didn't bring in Katooni. Still, I hope you all like that I brought Cassandra Cain in.

Will her background be different than from the comics, especially how we are in this universe? What will happen now that she has arrived? Will we see her in action? And what will happen when they find out what the Joker is up to?

Check out the chapter to find out and also again trying to make sure what I do fits in this universe since the DC Universe is on a whole other level. Both DC and Marvel. Both sides do not have any limits on what they can do, especially when it comes to bringing their characters back to life. Anyways, time for the disclaimer.

I don't own anything from the DC or Star Wars universe just my OCs. Also: Bold- means thoughts & Italic- will mean what an alien is saying in their native language. Now let's continue with the story and enjoy the chapter everyone.

Story II: Chapter XI

Seven years ago

Coruscant is a planet that has thousands of cities and home to different species that reside on the planet. Many coming from all across the galaxy and are trying to make a living. It is also filled with flying vehicles that travel around the cities and making their way around. Fortunately no accident have occurred that would cause many people to die from the amount of vehicles on the planet.

Coruscant also has its own weather control system that allows them to control the weather around the planet. Like for example if they wanted it to rain they would, but only once a month. However, the machinery was damaged during a fight between the super criminal Mr. Freeze and the hero Batman.

As a result the machine caused snow to fall on the planet. For the last few days the people of Coruscant have tried to adjust to the cold until repairs can be made to stop the snow. For the lower class who live below the city they are doing all they can just to survive the cold. Many trying to raise the heater in their homes, light some fire in barrels, or pay to buy warm clothing.

On level 1313 some people are seen trying to buy some warm blankets and clothing from merchants. One of these people is a cloaked figure who is seen going through the crowd, while a hood cover the face. The figure looked around seeing people fighting for warmth and even argue with one another. The figure turn away from them knowing there was nothing that could be done.

"Hey you!" a man shouted at the figure who turned around to see the man. "Get back here you brat!"

The figure took off running through the crowd trying to lose the man and his droids. The figure tried losing him through one of the buildings, which was crowded with people buying for things. The man had his droids open fire in the sky causing the people to run away in fear. The man took out a blaster and fired it at the figure.

The figure felt the shot grazing its right arm, but kept on running. The figure headed to the back of the store and locked the door. The figure then ran to the exit, but was then grabbed by the neck by a Trandoshan male. He picks the figure up by the neck before tossing the figure to a nearby trash container, face first.

"Hello girlie. Finally found you," said the Trandoshan as he held the hood of the figure who is revealed to be a girl.

She appeared to have short black hair, green eyes, and fair skin. She also appeared to have a bruise on her right eye as she tried getting up. The man and his droids broke through the door and met up with the Trandoshan. The man thanked the Trandoshan for his assistance and approached the girl.

"You shouldn't have tried running away. Your father is not very happy with you leaving him after the job," said the man as he aims his weapon at the girl.

She looked away from him knowing what she did was not a job, but murder. She could not speak though as she got up from the ground waiting for him to kill her.

"Oh I get it. You ran away hoping we would kill you?" the man asked as he sets his weapon to stun. "Oh no. Your old man is not done with you. You will come back with us so you can go on to do the next set of…"

Suddenly a sharp weapon is seen cutting through the man's weapon causing him to back away. He looks down to see the weapon in the form of a bat as his droids look up. There they see a man dressed in a dark suit with a Bat symbol on his chest. He orders his droids to fire, but the bat figure jumps over dodging the blasts.

He tosses more bat shape weapons as they blew up destroying the droids. The bat figure landed nearby as the Trandoshan charges at him. He dodges the attack as his right hand begins to charge up. He punches the Trandoshan in the face and shocked him with electricity.

He punches him again and shocks him once more causing him to stagger. He jumps up and kicks him right in the face and knocks him out. The man grabs one of his droid's weapon and aims it at the bat figure. However, while he was distracted the girl grabs the first bat weapon and stabs the man in the leg.

The man hits her in the face and knocks her away, but this distraction allows the bat figure to punch the man in the face. Breaking his jaw and knocking him down.

The bat figure turns to the girl as she turns to him with a bruised face. Both stared at one another looking each other in the eyes. As if they were trying to get a read on one another. After a minute passed the bat figure extended his hand to the girl.

The girl slowly moved her hand up and took his hand as he picks her up. The two begin walking out of the alleyway and towards the figure's vehicle as the sound of police sirens can be heard echoing around them.

Arkham

Cassandra opened her eyes as she recalled that night when Batman or rather Daniel saved her life. It was around the time he was starting to become the Batman and appeared mainly around the lower levels of Coruscant. Since that day she was adopted by Daniel, but was kept hidden since she was the daughter of two assassins who would come for her. So instead she stayed hidden, while she was trained by Daniel, Ahsoka, Abby, and Tatsu.

She even began to learn to speak thanks to Abby and a friend who despite being a criminal was someone who she cared for.

Despite knowing what she did and who her parents were, Daniel still took her in. Raising her like a normal child instead of an assassin like her father did. Even caring for her like his own, even if he won't admit it.

"Batgirl, you ready?" Batman asked as the two stood over the medical facility after making sure the hostages inside got to safety.

Batgirl nods in response as she began refocusing on the mission. "What do we do...first?" despite getting help on speaking she still needed more time.

"Find out more about Dr. Young," said Batman as he begins contacting his sister. "Oracle, go through the Arkham and Cadmus' computers. Pull up all you can find on Dr. Young. I'll go through anything you can find once I get to the cave."

"A Batcave? On Arkham?" Oracle asked surprised to hear there's a Batcave on the planet. "When did you set one up and why didn't you tell me?"

"I built it years ago just before the prison was set up. It's best to plan ahead for situations like this," said Batman who is glad he build another Batcave that wasn't found by Cadmus. "By the way, when were you planning to tell me who you were sending?"

"Oh right. Sorry about that, but with Ahsoka and Lux busy well I needed to send someone to help you," said Oracle who apologized to her brother. "Anyways. Why do you want to look up on Dr. Young?"

"She did something to Bane," said Batman as he explains everything to his sister.

From the Venom being drained from Bane's body, to a different serum used to make him stronger than in his regular Venom form, and how he believes it is connected to what Joker is planning.

"I see. So, do you think Dr. Young's been experimenting with Venom, the same chemical that turns Bane into that animal?" Oracle asked wondering why Cadmus would be interested in this.

"Yes. I'm worried. Bane seemed even more powerful than usual. Joker wants the Venom, and that can only be trouble," said Batman as he turns to where the cave is at. "We're heading to Dead Man's Point in Arkham North. I'll contact you once we're in the Batcave."

"Okay and be careful you two," said Oracle as she goes to look up what she can find.

Batman turns to Batgirl and placed his hand on her shoulder. "You ready for this?"

Batgirl looks up at Batman and nods in response. "I am ready," she replied.

Batman could tell she means what she says and takes out his Grappling Gun and fires it. "All right. Let's get going."

The two masked heroes head to the north part of the facility.

Meanwhile

Darth Maul heads inside the prison facility as he is instructed to round up any hostages to be used for an experiment the Joker is planning to use. So far he hasn't been able to find many who would be useful since they tried to run or fight back. So as a result Maul would end up killing them, though not always accidental.

Maul didn't care much for the Joker's plan and is only going along with this until he can get this collar off of his neck. So he can kill the clown and find Kenobi. He tried finding other means of removing the collar. Even use some of the sharp weapons he found to use them, but the collar would shock him if he tried removing it.

It appears the Jedi didn't want to take any chance with him if he did break out. He hears some noises nearby and spots Victor Zsasz nearby killing a doctor as he begins marking himself.

"Ah the resident psychopath. Adding another mark to your body?" Maul asked.

Zsasz turns to Maul while enjoying the feeling of his blade against his skin. "Yes. So many more to add, but the Batman has hidden many of the little piggies away. Must them all and free them from their miserable life," he soon stood up and turns to Maul. "Perhaps. I can help you be free from the pain and misery you have endured yourself."

Maul scoffed at Zsasz's idea and turns away from him before seeing the Joker appear on screen. "Ah the new warden himself. What do you want?"

"Hello spikey. I see you are looking for Kenobi?" the Joker asked as he chuckled. "Well, got some bad news. Old Bat got him a ride and is now gone. And just before the party."

Maul was not pleased to hear Kenobi escaped, but knew he will come back. He cannot resist the urge to return to make sure he is captured. As he spoke to the Joker, Zsasz begins approaching Maul. Slowly, carefully, and quietly as he prepared to add him to his mark.

The Joker noticed, but wanted to see if Maul could with the collar on. "Anyway. I need you to do me a little favor. I need you to go over to pick me up a noisy doctor that has some secrets I want her to reveal to me. If you do then I will invite you to the party I am throwing."

Zsasz leaps over to kill Maul, but the Sith Lord activated his lightsaber stabbing him through the gut. All while he continued to speak to the Joker and had his back turned to the murder.

"I am not interested in this party you are throwing. However, what I saw you do to Bane did raise my curiosity," while it is true Maul has no interest in Joker's stupid games. He was impressed with the serum he used on Bane to make him stronger than before. "I will assist you in whatever you need, but in exchange I want the serum and Kenobi."

The Joker began to laugh when he saw what Maul did to Zsasz and what he wants. "Oh that sounds like it could be fun. Very well. You have yourself a deal, but first I need you to find me Dr. Young. Get me her notes so I can perfect my formula."

"It shall be done," said Maul as he pulls his weapon out of Zsasz and swings it to take his head off. "Now, where is the good doctor at?"

Dead Man's Point

Batman and Batgirl managed to arrive to the north part of the prison where they got passed some of Joker's men. Knocking them out and making sure they are tied up. Once they took them out they headed through a cave that was blocked off. The location was used by the prisoners to take their own lives when they couldn't escape the planet.

Some even thought they could just jump into the water and escape when they heard stories from guards how there is land far from the island. This was a cruel lie though to give the prisoners hope. Many though were not foolish enough to believe this, but those who were desperate they would believe anything.

Batman explained to Batgirl to follow him once they make it to end of the cave. To stay close and not use her cape until they make it halfway down. She understood as they soon made it to the end of the cave. Looking down she sees how far up they are and could see so many rocks below them.

Batman motions for her to get ready as he jumps off first before she began following him. The two fell towards the water until Batman used his Batwings to glide around the hill. Batgirl did the same as she spots a nearby cave. The two land in the cave as she sees nothing here.

Batman walks over to the wall as a bright light began scanning him. Once it finished the wall began to open revealing a secret entrance. They walk inside as the door closes behind them and head down the long tunnel that leads them to a waterfall. Behind it though is a bridge that takes them towards the Batcave.

"On," Batman commanded as the facility began activating on voice command.

Batgirl looks around as the lights turned on revealing the cave. It looks like the facility has a lot of the equipment he has back at their Batcave. However, there is no Batmobile or of the high-tech tools he would have around. She then remembered him saying he had just started setting up so she shouldn't be too surprised.

He also explained he didn't want to bring too much of his advanced equipment to this facility. Concerned that if it is discovered it can be used against the guards or the employees.

Batman walk over to his computer and begins connecting his sister to the mainframe so she can send him the information.

"Found out something interesting in Cadmus's files. Turns out Dr. Young was heading up a project. It was big, lots of external funding. Here are the last notes she file," Oracle begins sending the notes to her brother as they appear on the screen. I can't make sense of it, what does it mean?"

Batman looks at the information and got an idea about this. "Looks like she was experimenting on the Arkham patients. This new chemical barely resembling the original Venom compound."

Batgirl looks at the information and the differences between the original formula to the new one. "She made many…changes to it…why?"

"Not sure," said Batman as he begins looking over it some more. "These number of changes appear to amplify the strength of the drug. Multiple references to a Titan formula. Even a small amount could trigger a Venom like transformation in the host, eliminating the need for the storage tank Bane requires."

Batgirl knew that isn't good. Bane was already a problem with the Venom formula he uses against Batman. If this formula is stronger than the one he uses then whoever they fight will make them more dangerous than Bane. However, she noticed something was off about these notes.

"They are…incomplete," she said pointing out to the formula and the missing ingredient for it.

Batman took notice of this too and knew she is right. "Cassandra is right. These notes aren't complete. The formula is missing! That must be the secret Dr. Young is hiding," this must be what Joker is looking for and why she needed to go to her office. "If Joker gets his hands on this, he will create an army of a thousand Banes.

"My God! Is Joker crazy enough to…" Oracle stopped herself when she realized what she was about to say. "What am I saying? Of course he is. You two have to stop him."

"We will," said Batman as he gets up and goes to one of his equipment and gives Cassandra a Batclaw to use. "We're going after her. She was heading to the mansion with Cash. We'll go up top via the catacombs."

"All right. Good luck you two," said Oracle as she goes to inform the others about what is going on.

Batman leads Batgirl towards the next platform as they go through another tunnel that leads them to another cave. In this cave they look up to see a venting grate that leads to the sewers of the prison. Batman took out his Batclaw and shows Batgirl how to use this. He fires the claw as it grabs the vent and pulls out the grate so they can go inside.

"Remember, stay close," said Batman as he uses his rocket boots to fly up to the vent.

Batgirl follows him as Batman helps her inside the vent and follows her as they go through it. They managed to make to a grate as they begin opening it. Quietly though when they hear one of Joker's men talking to the Joker. He appears to be all alone and with no one else around.

"Sorry, boss. Took a little longer to find him than you figured it would," said the henchman as he spoke to the Joker through a radio.

"Oh! I'm sorry I'll try and be more precise next time I'm planning a planet takeover," said the Joker who sounded annoyed with what his henchman said.

"Hey. I didn't mean…" the henchman tried to explain himself so he doesn't make his boss mad.

"Criticism I can take. I mean, I'm not perfect!" said the Joker as he interrupted his henchman. "Well. Come to think of it. I'm pretty close to perfect aren't I? Where was I? Oh yes."

Batgirl turns to Batman who motions for her to move in close to the criminal to knock him out. Batgirl nods and goes over to him, while the Joker continued to speak to his henchman.

"Criticism from a worm like you, a worm who is only crawling around free because I arranged to open his cell, is something I will not tolerate," said the Joker who clearly sounds upset with what his henchman said.

"I'm sorry, boss. I didn't mean it like that. Please," the henchmen begged for forgiveness knowing what will happen if his boss gets mad.

"Well, seeing how you're apologetic. I'll just have someone drive round to your house and break wife's legs," said Joker threatening the henchman's wife.

"But, Joker!" said the henchman until he was interrupted by his boss.

"You got a problem with my generous nature?" the Joker asked

"Err. No um, I guess not. Err, thanks…" said the henchman who needed to accept this.

"Don't mention it. Consider the matter closed," said the Joker as he moves on to the next topic. "Now then. Head on over to the others. You are all going to work with old Spikey Head to find the good doctor."

Before the man could respond Batgirl gets behind him and knocks him out with a sleeper hold. "You there? Hello?" the Joker asked when he didn't hear his henchman back. "Wonder who got you. Croc or the Bat? Croc old boy! You there?" he got no response and just chuckled. "No? Pity!"

Batgirl ties the man up and turns to Batman. "Croc? As in Killer Croc? He's down here?"

"Close by," said Batman knowing Croc is not kept in a normal cell. "He was too dangerous to be kept in a normal prison cell. So, they dropped him in a closed off sewer where they keep him locked up."

"Did Joker…let him out?" she asked as the two head down the sewer.

"Doubt it. But Croc is not our priority," said Batman as the two stopped when they saw more of Joker's men. "Let's just focus on getting out of here and find Dr. Young."

Batgirl nods as she took out two metal batons. "I am ready."

Naboo

Abby is in the Batcave going over the formula that they found that Dr. Young was working on. It appeared she was working on this formula for quite some time. It seemed she wanted to use this formula on dangerous patients like the Joker to help reduce their violent nature and cure them. However, she didn't have the money to work on this formula.

Thanks to Cadmus though and a secret partner that funded her work then she was able to get this formula. Using Bane's Venom serum, using the patients for test subjects, and using the technology Cadmus has she was able to make this Titan formula a reality.

"She should have stopped when she had the chance," she said as she hears Alfred coming down the stairs. "Everything all right?"

"Yes. Ms. Amidala has arrived with the children and she is just putting them to sleep. I trust everything is going well?" Alfred asked as he looks up at the screen to find the formula. "And what is that? A science project?"

"Dr. Young's science project," Abby replied as she looks at the formula. "We found out she has been using Bane and other patients for an experiment she is working on. With this formula she can transform a normal person into a dangerous monster. Stronger than Bane in his Venom form."

"Dear Lord. Why would she do that?" Alfred asked wondering why a respectful doctor like Dr. Young would do this.

"At first it didn't appear that was her intention," said Abby as she puts the formula away. "It looks like she was just trying to find a way to cure dangerous patients to make them sane. However, if Joker gets his hands on the missing notes he could weaponized the formula. Create an army of Banes. Something we can't allow."

"I trust Ms. Tano and Mr. Bonteri have been informed about this?" Alfred asked.

Abby nods in response. "I wish they were able to make it to Arkham to help Daniel out. Unfortunately the amount of travels they have been doing to find the bombs the Joker placed has overloaded the teleporter. We need to wait a while before we can use it. By then I just hope Daniel and Cassandra will be okay."

"I am surprised Master Wayne took young Cassandra with him. I would have thought after what happened with…that well you know he would have decided not to give her the cape," said Alfred hesitating to bring up the incident.

Abby sighed knowing Alfred is right, especially after what happened with Anakin. "I'm sure he doesn't want to risk her anywhere near the Joker, especially what he did. However, it's not like there is much he can do. With the Joker and Maul on the loose with all those criminals, he is going to need all the help he can get."

"I suppose," said Alfred as he sees Abigail working on something else. "Any luck on shutting down Luthor's laser shield?"

Abby shook her head. "These shields are all controlled by a signal that is coming from the prison. The only way to deactivate them would be to take control of the prison systems, which I am still having trouble getting in. Remind me to cancel any appointments with Luthor from here till the end of time."

"Noted," said Alfred as he goes over near one of the computers to check on the Batcave's supplies on Arkham. "It appears your brother managed to send over plenty of supplies and medical equipment. If he finds the notes he can find a way to stop the Titan formula."

"And reverse the effects of it. Let's see if we can fill in the holes to these notes so we can try making our own cure just in case," said Abby as she began working on figuring out the formula without the main notes.

Arkham

Batman and Batgirl managed to make their way through the main sewer junction after taking out Joker's men. They also found the latch that leads to Killer Croc's lair. It was locked and Croc couldn't break through it when he saw them. Batman knew they didn't need to deal with Croc as long as he is locked in his cell.

They made it to the catacombs where they found what appeared to be large brick structures that appeared old. Very old. Batman knew this would lead them to the outside, but they needed to get up there. Batman and Batgirl used their rocket boots to fly up to the top as Ahsoka contacted them.

"Batman. You there?"

"I'm here. Go ahead, Batwoman," said Batman wondering what Ahsoka needed.

"Good to hear from you. Cassandra there too?" Ahsoka asked as she spoke to Batman while she is at Lux's apartment.

"Yeah, she's here," said Batman as he turns to Batgirl who is looking around the structures. "What do you need?"

"Oracle told me what happened and about what Dr. Young is working on. Lux and I took a look into it while she works on figuring out the formula," said Ahsoka as she looks through her holopad what they found. "We looked into her bank records. There have been multiple payments starting months ago and then nothing. We believe she must have had another partner outside of Cadmus. Someone they didn't know."

"Do you have a name?" Batman asked wondering who else knows about the formula.

"The payments came from a company owned by a Mister Jack White," Ahsoka replied as she read the name from the holopad.

Batman recognized the name and knew who it is. "One of Joker's oldest aliases. Joker paid Dr. Young to create his army and then stops. Doesn't make any sense."

"Well, we thought it was strange too. So, we looked into it more and found out the payments weren't exactly stopped," said Ahsoka as she looks at Dr. Young's account. "They were actually declined a few weeks ago. She put a block on her account."

"Sounds like she had a change of heart. She tried to block the payments. Joker doesn't like it when his partners try to back out," said Batman who now believes once she found out what was going on she stopped.

"So he decided to get himself back to Arkham, find his formula, and create the army himself," said Ahsoka who figured this would be something Joker would do.

"Why did she not…tell Cadmus?" Batgirl asked who heard the conversation through her cowl.

"Most likely she didn't want them to know she was being used by the Joker and what she made," said Batman as he figured Dr. Young didn't make the formula to be used as a weapon by Cadmus.

"I just hacked into her email accounts. Two mails stand out," said Ahsoka as she reads them. "The first is a resignation letter dated last week. Sounds like she was trying to get away."

"And the second?" Batman asked figuring it must be from Joker.

"A message from Joker, well Jack White. It's a long thread. She's beginning to stop the experiment. Says it's too dangerous," Ahsoka continue reading the message as she summed up what she is reading. "He's not listening. Random threats to her family a couple of bad jokes…a picture of a dead baby and a threat."

"Go on," Batman asked wanting to know what Joker said to threaten the doctor.

"He says, I'm coming for you. I want what I paid for. And then another joke about wheelchairs, lovely…" said Ahsoka rolling her eyes at that knowing if Abby did meet the Joker she would shove her wheelchair up his ass. "And a drawing of some kind of four-legged animal."

Batgirl approaches Batman as the two made their way down the tunnel/ "She's scared…that's why she is running."

"And that's why we need to find her," said Batman as he finishes his conversation with Ahsoka. "We're coming up to the surface. Keep me posted of anything else you find. If you can find her family and keep them safe. Don't want Joker to harm them."

"You got it and be careful you two," said Ahsoka as she shuts off her communicator.

Arkham East

The Joker's men managed to take this part of the island after breaking into the armory and began using the weapons to push the Clone guards back. The Clones barricaded themselves in the Arkham mansion. The Joker's men began setting up snipers on the towers and mansion balcony in case Batman shows up. The rest headed off into the Botanical Gardens.

There the Joker is making his way inside to begin his experiments. Maul and his men arrived as they stood outside the mansion. He knew the doctor was inside somewhere and they will find her. He turns to his men as he motions for some of them to surround the facility to make sure the doctor won't escape.

"Now then, the Joker says to bring the doctor in alive and to hold the others as hostages for the Batman," said Maul as the Joker's men groan a little that they won't be able to kill anyone. "However, he didn't say how many to spare. So, if any resist then kill them."

The Joker's men all cheered as they follow Maul. The Sith Lord used the Force to open the door by force and march inside with the men.

Meanwhile, two of Joker's men are on the other side of the mansion. Near a door that doesn't appear to be lock. The two decide they will go inside when they hear some noises nearby. They turn around and spot an Astromech droid all alone. The men lowered their blasters figuring the droid is not threat to them.

However, the Twi'lek pilot that crashed earlier came out from behind a statue and shot both men. Killing them both as she rushes over to grab their weapons. She goes to open the door when a third of Joker's men came over and aims his blaster at her. He goes to shoot her when the droid used a taser to shock him.

The pilot kills the criminal as he fell down. "Good work, Chopper. Now, let's go inside and warn them what is going on."

The droid replied to the pilot as they head inside and lock the door to find the Clones that are inside.

Hope you all liked how this chapter went. Yep, we saw Cassandra's background and how she met Batman. We also saw Maul killing Zsasz, which means he won't get to interrogate Dr. Young. Who will get that chance now? Well, kind of obvious who it will be.

Also, if you are all wondering how Anakin died. I gave you a hint. At the hands of the Joker. How it happened, well you can figure it out how he did it.

Anyways, thanks to everyone for the reviews and to my friend for his help too. I appreciate it and how will Hera's role in the story work here? Well, keep on reading to find out. If you liked how this chapter went then leave some reviews.

Just nothing negative please. If you didn't like this then don't leave a review. Take care guys and see you all next time.
