Last time on Ben 10: Arkham Knight.....

After a lots of turns on the roads the Vehicle reached the entrance to the GCPD. As soon it parked, Batman opened the back seats of the vehicle to come out.

"Who taught you how to drive?" Asked Poison Ivy."Batman Grabbed her by the arm and was taking her to a prison cell.

Ben followed them. "Scarecrow is going to break you Batman." Said the Same Militia that his right arm was broken, while he was behind bars. They just ignore him and keep walking.

"Civil unrest? The city is under attack and we don't have the manpower to deal with it." Said one of Batman trust police allies Commissioner Gordon.

"Well look who it is." Said A police officer with a hook for his right hand, since it was biting off from Killer Croc, Cash.

"Ivy. Well that is one less thing to worry about." Said Gordon. "Is the isolation Chamber ready?" asked Batman.

"Glad you putting it to good use." Said Cash as he looked at the isolation chamber.

Batman then brought Ivy to the isolation cell and now she is behind bars(well not technically but it still works.)

----------------------------

GCPD Lockup............

Batman and Gordon were having a talk about the incidents that happen so far after the Evacuation. Ben wanted to help Batman, but Ben felt like he got to prove himself more. SO Ben will find a way to prove himself to the batman by capturing a villain.

Ben decide to go up and went up to Cash. Since he is the police cop keeping track of all the police reports that is happening right now, he would at least give Ben something to do.

"Hey Cash?" asked Ben. "Yeah Batman new partner?" asked Cash. "The Names BEn. I want to prove myself to Batman. Is there any tough challenging task I can do like solve something or bring in a supervillain?" asked Ben.

"Well there is this." Said Cash. He then brings up info about a sickening thing. A body nailed to a wall and words that saw "Failure."

"A body turned up at the Bridge. A unknown murderer did this. The boys seem scared when trying to examine it. You can try to take a look at it but..." When Cash turned around, Ben was gone.

"Just like Batman. Always disappearing without a trace." Said Cash

-----------

At the Bridge...

Ben was at the Location of the Boyd nailed to a wall. Ben clutched his fist and can't believe someone this sick can do this to a incident person. He also notice that there was opera music playing.

Ben turned on his watch and turned the Dial. When he slam the dial down, A green light was shown in his place.

What stood in his place, was a dog like creature with no eyes but just lots of Orange fur. It was Wildmutt.

Wildmutt went up close to the body and used his super smell to pick up at least a smell that could be a lead.

THe entire body was bleached to cover the person tracks but one track he forgot was right behind the back of the person.

Ben got the sent and then followed his nose to it might lead him.

THe smell was coming from another island, Called Founder's Island. Ben had to jump into the cold water and swim to the other side. He then climb back out o f the water and shake his fur to get the water out.

He then continued to follow his nose until it lead him to a shop that is named Pretty Dolls Parlor.

THe watch timed out and in a red light, Ben returned to his human form. "Who's side are you on?" asked Ben as he was arguing at his watch.

As soon Bne enter the building, he thought it look like a normal room but as he continued to look around, he heard a little bit of that same opera music coming from the back door.

"Gee. You think villain thesis day would remember to be careful of covering there tracks." Said Ben. When he opened the door, he heard the Music better.

THe more he try to get closer, the more he hear the music getting louder and louder.

THen he got a room that a man is near a operating table and has a knife in his hand and a pig mask on his face. HIs name is Professor Pyg.

And this surprise Ben the most of which person was on the operating table, A old foe of the great Batman, THe joker, he is strapped to the table.

"Look Pyg can we just be pals and let me go?" asked the Joker as he was trying to ask this new villain to be set free.

"No. Pyg must fix you. Make you better." said Pyg as he was about to get a knife out.

WHile they were chatting, Ben look at some paper that was on a box. He read the reports of this Pyg guy and all keeps talking about is making human perfect. This made Ben shiver in his spine. Ben then walk into the room where the villain is.

"It is over for you Pyg. Release them." said Ben. "No,no,no,no,no. Pyg not ready yet. He is all unique and wrong. Messed up, inside out." said Pyg. "Pyg make him better. Pyg make all of us better." said Pyg as he look around the room as there were more people. SOme of them were people were in patient close and has a make strapped to their faces. THe others are people are not changed into Dollotrons.

"You're insane." said Ben. Pyg then pointed a finger at Ben. "And what are you?" asked Pyg. "I am here to stop you pyg." Said Ben.

Oyg then ran to the exit behind him and watch ben from on of the look through windows. Ben then went to the operating table and freed the Joker.

"Thanks kido. Normally the Batman would have save me." said Joker. As he got himself off the operating table. 

Just then 13 Dollotrons came to the ground from their cages. Pyg then ran through the window.

Ben dodged the incoming knives that Pyg was throwing at him. BEn then though one of the knifes back at Pyg which hit his mask.

Ben then came up to him and kick him really hard in the face, which in turn broke the mask. The DOllotrons just stood there waiting for orders from Pyg.

Ben went to a power box and pulled out some wires and the cages holding the surviving victims were free.

Just they got out of the cage, Batman came into the Room. Batman notice the Joker examining Pyg. Batman then looked at BEn for a second. THen he went to Pyg and carried him to Police that was just outside.

-------

Back at GCPD Lockup......

Joker got his own private cell where he wouldn't kill any of the inmates or any other super villains, just in case.

While Pyg got through into Maximum security prison that was behind Cash desk.

"How did you find me?" asked Ben. Ben then pulled a small tracking device from the back of Ben neck. "Oh." said Ben.
