They entered the corridor. Walking through Ben saw the bodies of multiple dead guards. "Joker came through here these poor guards never stood a chance." Batman said solemnly.

"This is insane. What would push someone to do this. Killing just because he can. There's no motive. There's no reason." Ben said.

"Joker has always been like this. He's never had any regard for human life. He finds joy in killing people and causing chaos." Batman said.

Ben looked at Batman. This man was like nothing he had ever faced before. A man who killed just because he could. With no real end goal in mind. This kind of person isn't like anyone Ben had fought. Sure he had fought killers but they all had a goal. Even vilgax had a goal in mind despite how much he seemed to enjoy killing.

A small confrontation happened in the corridor. Batman beat the criminals before Ben could even reach the Omnitrix.

"Batman over here." A guard said. Batman and Ben ran over to him. "Batma- what's with the kid?" The Guard asked.

Ben rolled his eyes. "I'll show you what's with me." He went into the Omnitrix. He selected Fourarms and slammed down on the core.

He transformed into a six inch tall bipedal frog like alien. He had a green jumpsuit and gills. His green eyes had black rectangular pupils. "Grey Matter? So not what I was going for." The alien said.

He quickly turned back into Ben. "That was unnecessary." Batman said.

Dispatch came on through the guards comm. "Mayday we have a situation in the pacification chamber. It's Zsasz he's got Mike. He strapped him to the chair."

Before anyone spoke Batman began to head toward what Ben assumed was the pacification chamber. He followed Batman. The guards saw the two of them. They looked a little confused at the sight of the teen hero, something that Ben still didn't appreciate very much, but ultimately turned their attention to Batman.

"It's Zsasz he's got mike strapped to the chair. He'll fry him if he sees anyone get close." He said.

Ben went into the Omnitrix. Batman stopped him. "Wait. You never get the alien you want. Something as High tech as that I doubt it's the watches fault." Batman said.

"So?" Ben asked. "So… technology can be delicate. This time don't slam down on the core." Batman said.

Ben looked at the man in the Bat costume. "Are you mentoring me?" He asked.

Batman remained silent. Ben did as he was told. He searched the playlist and selected Big Chill. When the core popped up Ben pressed it down instead of slamming down on it. He transformed into a large humanoid bug like creature. He was skinny and had a blue cloak. His green eyes looked similar to bug eyes and his mouth was just an open line of teeth. The Omnitrix was on his chest under his cloak.

"Big Chill? Seriously? Sweet." The Alien said. "Now that you have what you want what's your plan?" Batman asked.

"Simple fly through a couple." Big Chill said in a raspy voice. He turned intangible and flew into the wall. Thinking about where he would best appear. He flew out of the wall behind the psychotic killer.

He walked over to Zsasz. "I swear if I see the Bat. The guy dies." Zsasz said. Big Chill leaned over looking at the chair. He saw the wired hooking up to a machine.

Seeing that Zsasz still had not noticed him he turned to the machine. He inhaled deeply and blew cold air against it. The machine began to freeze and stopped working. Zsasz looked at the machine and then at Big Chill.

"Seems to me like you're not frying anyone today. Now you should really chill out." The alien punned. He breathed his icy breath on Zsasz causing him to be surrounded by ice.

Batman joined Big Chill in the room, the former turned back into Ben. Ben smirked looking at Zsasz.

Suddenly the screens around them turned on. Ben saw a blond woman wearing a skimpy maid uniform. She had white makeup on and black makeup around her eyes. Ben ruled that she was working with the Joker.

"Hiya B-Man." She said. "Quinn." Batman said darkly walking up to the screen.

"The One and Only. How do you like my new uniform." She said showing off her figure.

Ben looked away when she did this. "Oh… and there's that new kid. What am I too hot for ya?" She asked.

Ben didn't respond he refused to look at her. "Oh I almost forgot I have something to show you. Wait right there B-Man." She said moving off screen.

She came back with the Warden. He his hands were bound and he was gagged. "I'm subbing for the old man here. Ol' sharpies never been happier." She said getting uncomfortably close to the warden.

"Step back from him." Ben said turning to face her. She looked at him through the camera.

"Ooh you're pretty cute hun, any chance you wanna switch over and work with my darling Mista J?" She asked with a wink.

"Are you… flirting?" Ben asked arching an eyebrow. "How about no. In fact I'm gonna be the one who catches your every own Mista J." Ben said in a voice that clearly mocked her.

She gritted her teeth. "Why you rotten kid. You ain't doing anything stuck in there!" She yelled shutting off the screen.

"She's locked the doors. She's trapped us in here!" A guard exclaimed panicked.

Ben tapped the Omnitrix faceplate and got ready change forms but Batman stopped him. "You don't need to use that. It's always worth to take a closer look around." He said.

Ben looked at Batman. Once he again he got the feeling that Batman was mentoring him. Teaching him how to be a better crime fighter. Why would this hero who swore that he works best alone be teaching him to be better at crime fighting? Come to think of it most of the situation with Zsasz had ended up being somewhat akin to a lesson. Learning how to better control the Omnitrix, showing that he could think strategically instead of just going for hard hitters, and now telling him to take a closer look at his surroundings.

"Hey. I was just joking before but… are you actually mentoring me?" He asked. Batman looked at him.

Without answering he walked over to a Air vent and pulled off the metal grate blocking it. Ben smirked. Maybe this Batman wasn't so bad to work with… maybe.
