A/N: I hope you guys enjoy this chapter! I'm getting excited on this plot. Review please! I want to know what people thing. PM or review any suggestions on how I can extend the plot. This is a SYOC so I want other people's suggestions :). I don't own YJ.

Reminder: Italics: They are speaking through the mind communication device things.

Remember, this is a recon mission. Do not attack unless necessary. Matthew said. Joker, Poison Ivy and The Riddler walked into view. Delta shivered. She had gone against Joker before, back when she didn't know she had powers. It resulted in a deep scar on her shoulder. The three walked into the warehouse. Gray Ghost and Relic shifted positions.

Anyone see anything? Dominick asked.

From our side, it looks like they're planning something. There's a lot of paper. Owen said.

We need to see those papers. Matthew said, trying to get a look.

I got it. Delta said, taking out binoculars. She looked up, with a shocked expression. "Del, what is it?" Matthew asked. She looked at him, worried.

"It's a doomsday device… They're going to kill thousands." Matthew gulped, but straightened himself out. "We need to tell Batman."

Guys you hear me? Delta asked.

Yes. Jimmy said.

Yeah, but Owen is annoying me again. Mika complained.

What now? Dominick asked. Mika glared at Owen who was next to her. "Owen I swear touch it again and I'll murder you." She said, shoving him away from the latch that opened the window. "Relax. Why are you stressed about a latch? It's not going to open." He said. He put his hand on the latch. There was barely any room as they were surrounded by crates, boxes etc. Both of them were literally shoulder to shoulder. "Just don't touch it. If it opens it's your fault." Mika stated, looking into the window. "Oh there you go again, worrying about everything and blaming me." Owen said. Mika glared at him. "Well maybe it's because it's always your fault." She said, jabbing a finger at his chest. "You need to loosen up! You're too uptight." Owen said getting up. He was starting to really get annoyed. "I am not uptight! I'm just being responsible!" Mika said, standing up as well.

Mika! Owen, shut up! Jimmy said through the communicators.

You'll blow our cover! May we remind you that we can hear you guys thinking! Delta said. Jimmy and Dominick were making their way down the roof. Owen and Mika completely ignored their friends' warnings. "You come here, acting like you own the place when we didn't meet you until recently." Mika told Owen.

"Me? I just want to fit in but you are making it awfully hard!" Owen said angrily. Mika got frustrated. "Ugh!" She yelled, slamming her hand onto the window by accident. The hinge broke and the window fell and shattered inside the building. Before the two could react, Joker, Riddler and Poison Ivy looked up.

"Look what you did!" Owen yelled. "Run!"

"It's those other Justice League brats! Go now!" The Riddler yelled.

Mika! Owen! Get out now! Delta yelled.

Mika and Owen both turned around, ready to run, but saw Joker and Riddler in front of them. "Don't try running children. Haven't you learned anything from your mentors?" Joker asked, giving them his sick smile.

We need backup. Owen said.

Right. We're coming. Dominick said.

Us too. Matthew said. Dominick and Jimmy got to the place as fast as possible. "Oh look, more of them. Let's just end them." The Riddler said.

"Oh we're not that easy to end." Jimmy said. "Now!" Dominick shot an arrow which Joker dodged. Jimmy then used his powers to throw the crates at both the villains. They dodged again. Arrow after arrow was fired and Owen was using his powers, making Joker and Riddler stumble a bit. Suddenly, Matthew and Delta showed up. Joker looked up and smirked. "Well, isn't it our dear Delta, pleasure seeing you again darling, I see you brought your friend. Hello Dash." Dash ran up to him and threw a punch. It stunned him for a bit. Riddler on the other hand was busy with Mika and Dominick who were shooting at him and throwing punches. They were fast, but Riddler was faster.

Joker soon regained balance and stood up. "That's rude. Ivy!" He yelled. Before any of the teens could react, Poison Ivy appeared. A vine wrapped around Owen's neck. "Echo!" Mika yelled, trying to rip the vine off. He struggled, but collapsed.

"Oh don't worry, he's not dead." Poison Ivy said.

"Kage, take Echo and go! Jimmy, help her. We've got this." Delta yelled, punching Poison Ivy. Mika and Jimmy nodded and took Echo. Jimmy helped them get away as fast as possible. Poison Ivy tried attacking Delta, but she was prepared for this. The fight between the girls continued. Dominick shot arrows non-stop at Riddler, hitting him every so often. Riddler smiled as he coughed from a gas arrow. Dash was throwing rapid punches at Joker, but he didn't notice Joker picking up a pole. BAM! The pole came in contact with Matthew's ankle. A sharp pain spread through Matthew's ankle and he fell to the ground. Shit. He thought. "Always go for the legs of the speedster." Joker said. Joker looked up.

As he did this, Riddler took out a gun and aimed for Dominick. BAM! A shot was heard and Dominick fell to the ground. "Relic! Are you okay?" Delta asked, hearing the shot. "Gah! My shoulder." He yelled. Riddler kicked him, making the pain worse. Delta looked up from her fight and saw Joker take out a knife. No. She thought. She knew she had to use her powers. Okay Aaliyah, you can do this. Stay in control! Stay in control! She thought. She threw a punch to Poison Ivy's jaw, making her collapse. She looked up and made eye contact with Joker. "Argh!" Joker yelled, clutching his head and falling to the ground. Riddler looked shocked. "Delta!" Dominick and Matthew yelled. Delta stood up and stared down Joker. Joker was bending over in pain. "Delta control it! Don't lose your control again!" Dominick yelled.

"I-I ugh!" Delta yelled, struggling to keep control.

"Just don't! Your alter-ego is going to damage you! Keep control!"

Meanwhile, Matthew stood up and tried shaking his ankle off. Good enough he thought. He sped over to Dominick and told him to hold on. Dominick did as told. Just as Delta was about to lose control, he grabbed her by the waist and sped away.

Matthew got Dominick and Delta back onto the jet where Delta looked dazed. She shook her head. "No…" She muttered.

"You didn't lose control just yet." Matthew said, reassuring her. Owen was still unconscious on the medical bed. "Mika, help." Matthew said. She and Jimmy rushed over to them. "Oh gosh. Okay, Dom, lie down. This might hurt a bit." Mika said, helping him lie down. Jimmy gave Delta and Advil and Matthew got a bandage and bandaged up his ankle. "No running for about a few hours." He muttered.

"I'll fly us back. I kind of know how to fly this thing." Jimmy said. The team nodded. As he flew the jet, Delta dialed up Nightwing.

"Hey little sis' how was the mission?" He asked, appearing on the screen. He was with Tim and Zatanna in the Batcave. The three of them looked up and saw the injured teens. "What happened?!" Zatanna yelled, a look of concern plastered onto her face. "They came after us." Delta said, the headache going away.

"We had to leave, it was going to far. Dominick got shot." Matthew said, glancing at the monitor. "Oh gosh, go back to the cave now. We'll go there first thing in the morning. All those not injured, help the others to the infirmary. We need to talk about this." Nightwing said. Delta nodded. "Oh and we did find out their plan. It's a doomsday device. A nuclear reactor. A chain of explosions and the world will suffer." Matthew said.
"Right. I'll report to Batman and Superman." Nightwing said, not looking at the screen. Tim saw the disturbed look on Delta's face. "You used it again didn't you." Tim asked her. She nodded.

"It was going to far. I had to. I almost lost control again…" She trailed off. Nightwing sighed. "We'll talk about this in the morning. Get rest. Nightwing out." He said. With that, Delta hung up. The rest of the ride back was silence.

In the cave…

Owen regained consciousness and put a neck brace around his sore neck. He avoided Mika who was helping Dominick onto an infirmary bed. Jimmy was helping Matthew suspend his ankle on his leg. "Here, pain killers. Double for you Matt." Delta said, giving them both pills and water. "We'll see you tomorrow. Night." Mika said. The two boys nodded. As the team walked down the hallway, they were rubbing sore spots. "Well good night." Jimmy said, entering his room.

"Night." Owen, Delta and Mika said.

Everyone fell asleep instantly except for Delta. She stared up at her ceiling. She felt something, a sick feeling in her stomach. One she normally gets if something bad will happen. Shaking it off as post mission stress, she undid her hair and threw her blankets over herself. She slowly drifted off.

In Joker's HQ…

Joker sat upright, awake. He looked around to see Poison Ivy and Riddler talking about something. "Joker." Ivy said, turning to him. "Do you remember what that girl did to you?" She asked. He looked at her.

"It was the most pain I have ever felt. How?" He questioned.

"She has powers. I saw her eyes glow red." Riddler said. Joker shook his head.

"That can't be. She's one of the Bat brats. If she had powers, we would have known." He said. "Well she does. And they're powerful. They're going to use that." Riddler said. "Yes, they are powerful, making someone feel so much pain when that someone would not feel any? That's power. We need a way to stop her." Ivy said. Riddler glanced at Joker. "Or… we can use her." Joker and Poison Ivy looked at Riddler who paced around the couch. "That other boy, Gray Ghost was helping her, helping her control her powers. The only reason why we haven't known about this is that they have been hiding it. She can't control her powers. He also said something about an alter-ego. I think something evil inside her."

"If we get her to use her powers and shift, we can get her on our side. She's weak with her evil side. Her mind is week." Ivy said. Joker smiled.

"I'm sure dear old Bats won't want his dear daughter to die or become evil. She's powerful. If we get her, we can lure in any of them. If she's on our side, we can win. No more Justice League and their brats." Joker said, clasping his hands together.

"She's weak with her mind. We need mind control. Something to use in a surprise attack so she's vulnerable." Ivy said.

"We can attack when they're least expecting it. Pretend to try and take something. When they attack, we injure all of them until she is the only one left. Her power comes from her eyes. If she can't see she can't use them. She'll get desperate and lose control in the heat of the fight. From then, we use mind control and turn her into our own soldier." Riddler ranted, excited about the plan.

"Yes. We need to get her evil. She'll be the power. She can kill anyone. Mind control…" Joker drifted off. He gave his signature evil smile. "I know who to ask."
