Infiltrator

Gotham City

August 7, 20:41 EDT

When Oliver had called me out to Gotham, I had assumed that it involved some sort of team-up with Batman and Robin. I was quite incorrect in that thought. I arrived at Ollie's rooftop coordinates and waited for him to meet me there. What surprised me was when I was joined not only by Green Arrow, but by Batman as well.

"Good. You're here." The Dark Knight acknowledged my presence with a nod which I returned. I crossed my arms over my chest, waiting for an explanation.

"There's someone we want you to meet." GA began, "We found the archer who helped you a couple of days ago against Amazo. And we want them to join the Team."

I arched a brow in surprise, "You've given up on Roy, I see. So who's the mystery archer?"

Someone leapt onto the roof behind me and turned to see who it was. It was a girl, about my age, with long blonde hair and gray eyes that rivalled mine in shade. She was clad in a hunter green uniform that exposed her stomach and in her hand she held a matching green bow.

"That would be me." She answered with a smirk, extending her free hand, "I'm Artemis. And you must be Wildcat."

"That's right, but you can call me Kara." I responded shaking her hand firmly, "It's great to meet the person who saved our speedster from being crushed into dust. I'm looking forward to working with you."

"Likewise."

"Artemis will be meeting the rest of the Team tomorrow." Batman said, "But since the two of you will be working in Star City during your downtime, we thought it would be best for you to be acquainted ahead of time."

I nodded in understanding at the Dark Knight and looked to Oliver for further input.

"Roy is off the grid right now so we don't know where he is. He won't be thrilled about this, but he'll have to deal. For now, I'd say we call it a night. If the two of you could meet here tomorrow at 1:30, we'll zeta to the Cave together."

"That shouldn't be a problem, GA." I replied for both of us.

"See you both tomorrow then." Batman dismissed us before disappearing into the night.

Mount Justice

August 8, 14:20 EDT

"Recognized: Wildcat, B-zero one, Artemis, B-zero eight, Green Arrow, zero eight."

I had been invited by the others to spend a day on the beach outside the Cave, but an assassination attempt on the Mayor of Star City prevented me from going. Batman and Oliver told me to keep Artemis a secret until she arrived, which was easy enough. Unlike Wally, I can keep my mouth shut.

As we stepped onto the main floor, I heard Artemis gasp as she took in the Cave for the first time.

"Pretty cool, huh?" I asked with a grin. She nodded slowly, continuing to look around.

"Way cool."

"Team, report to the Cave." Batman called out over the comm. A few more minutes went by before everyone came back, changed into their uniforms from their beach attire. Smiles appeared on their faces when the saw me, followed quickly by looks of confusion seeing our new archer.

"Everyone, this is Artemis. My new protégé and the newest member of the Team." Green Arrow explained. For a moment, no really did anything. But then, M'gann and Robin smiled, Superboy nodded and crossed his arms over his chest, and Kaldur stepped forward, extending his hand.

"Welcome to the Team. I am Aqualad, this is Robin, Miss Martian and Superboy." Kaldur greeted. Artemis took his hand and shook it confidently. While the other members of the Team introduced themselves, I hung back by Green Arrow.

"Heard anything from Roy yet?" I asked, hoping he would say yes. But he shook his head solemnly.

"'Fraid not, Whiskers. But Canary and I are doing everything we can to find out where he is."

"Recognized: Kid Flash, B-zero four."

"The Wall-man is HERE!" Wally emerged from the zeta tube dressed to hang out on the beach, carrying an excessive amount of beach items, "Now let's get this party star-"

The speedster tripped over a towel and landed on his face, dropping everything he was holding and earning an intense glare from Batman.

"Ted." Wally finished his statement weakly as he stood himself back up. The others turned to face him, exposing him to Artemis.

"Wall-man, huh? I love the uniform. What exactly are your powers?" She smirked. I stifled a laugh, but it was hard to hide the amusement on my face, even with my cowl on.

"Uh, who's this?" Wally asked.

"Artemis, your new teammate." She replied smartly.

"Kid Flash. Never heard of you." The speedster answered. Oliver walked over and set a hand on Artemis' shoulder.

"Um, she's my new protégé." GA explained. A look of surprise fell on Wally's face.

"What happened to your old one?"

"Recognized: Speedy, B-zero seven."

"Well, for starters, he doesn't go by Speedy anymore." Roy entered the Cave, decked out in a new red, black and gray uniform, still sporting the domino mask and carrying a new bow, "Call me Red Arrow."

"Roy." Ollie said with shock, "You look-"

"Replaceable." Roy spat at his former mentor.

"It's not like that. You told me you were going solo." GA tried to explain.

"So why waste time finding a sub? Can she even use that bow?" Roy questioned angrily. Artemis stepped forward proudly.

"Yes, she can." She answered shortly.

"Who are you?" Wally interrupted.

"I'm his/she's my niece." Oliver and Artemis answered quickly. It was a rouse of course, but under strict orders from Batman, I wasn't allowed to say anything about Artemis' secret identity.

"Another niece?" Robin asked.

"But she is not your replacement." Kaldur told Roy, "We have always wanted you on the Team. And we have no quota on archers."

"And if we did, you know who we'd pick." Wally continued. I elbowed him in the ribs sharply.

"Whatever, Baywatch, I'm here to stay." Artemis said, rolling her eyes.

"You came here for a reason, Roy," I stated, turning the conversation to something other than his unwillingness to join the Team, "what is it?"

"A reason named Dr. Serling Roquette." Red Arrow replied, walking over to the Cave computer.

"Nanorobotics genius and claytronics expert at Royal University in Star City." Robin said, pulling up Roquette's file on the computer, "Vanished two weeks ago."

"Abducted two weeks ago." Roy corrected, "By the League of Shadows."

"Whoa, you want us to rescue her from the Shadows?" Robin said, extending his fist to Wally who bumped it excitedly.

"Hard core."

"I already rescued her." Roy said, crushing their dream, "Only one problem. The Shadows had already coerced her into creating a weapon. Doc calls it the Fog, comprised of millions of microscopic robots, nanotech infiltrators capable of disintegrating anything in their path. Concrete, steel, flesh, bone. But its true purpose isn't mere destruction, it's theft. The infiltrators eat and store raw data from any computer system and deliver the stolen intel directly to the Shadows. Providing them access to weapons, strategic defense, cutting-edge science and tech."

"Perfect for extortion, manipulation, power-broking. Yeah, sounds like the Shadows." Artemis finished.

"Oh yeah, like you know anything about the Shadows." Wally said with a pout on his face. Artemis glanced over at me and we both smirked at Wally, who grew increasingly frustrated, "WHO ARE YOU?!"

"Roquette's working on a virus to render the Fog inert." Roy continued.

"But if the Shadows know that she can do that, they'll send someone after her to make sure it can never be used." I finished. Roy nodded.

"She's off the grid, right now. I stashed her at the local high school."

"You left her alone?" GA asked incredulously.

"She's safe enough for now." Roy shot back.

"Then let's you and I keep her that way. Like we used to."

"You and I? Don't you want to take your new protégé?"

Green Arrow looked over at Batman, who narrowed his eyes at the archer. He sighed and turned back to his former student, "You brought this to the Team. It's their mission, which means it's hers now too."

"Then my work here is done." Roy shoved past us and made his way over to the zeta tubes.

"Recognized: Speedy-"

"That's Red Arrow, B-zero seven. Update." And then he was gone.

Happy Harbor

August 8, 21:53 EDT

Aqualad, Artemis, Kid Flash, Robin and I stood waiting in the computer lab of Happy Harbor High School while Dr. Roquette worked on the virus. We had already been there for a few hours and had no activity. M'gann and Superboy stood outside on perimeter.

"Everyone online?" M'gann's voice suddenly echoed in my mind. Artemis clutched at her head, not used to the telepathic link.

"Ugh, this is weird."

"And distracting. Coding a distributive algorithm on a kiddie computer with less RAM than a wristwatch is hard enough. Now I have to hear teen think in my skull?" Dr. Roquette snarled telepathically. I huffed angrily, earning a soft glare from Kaldur.

"Lady, do you always complain when someone tries to help you?" Kid asked.

"Pot, kettle. Have you met?" Artemis smirked.

"Hey, I don't need attitude from the newbie that drove Red Arrow off the Team."

Artemis leapt up from where she was sitting and jabbed a finger at KF, "That is so not on me."

"Fate of the world at stake!" Dr. Roquette interrupted.

I straightened up and stood between the archer and the speedster, glaring at both, "Enough you two."

"She started it!" Wally complained. Artemis began making her way toward the door.

"How 'bout I just help Miss Martian and Superboy patrol the perimeter?"

"Good idea." Kaldur replied.

"You might cut her some slack. It was her arrow that saved your butt against Amazo." Robin pointed out to the speedster with a grin.

"What? No, that was Speedy's- I mean, Red Arrow's arrow, right?"

"Not quite, Kid." I replied.

"Humph," Kid huffed, "Well, still not giving her the satisfaction."

"You know I can still hear you." Artemis called out as she walked out to the perimeter. Wally's eyes went wide in a combination of surprise and frustration. He grabbed his temples and groaned out loud. Aqualad ignored Kid and went to stand behind Dr. Roquette.

"The virus will not be of much use if we cannot find the weapon. Can you track it?" He asked the doctor.

She whipped around to glare at him, "My utility fog is NOT a weapon. It's science! Brilliant science! And of course I can track it! But I'd have to go online. Might as well rent a billboard with this address and 'Assassinate me' written in neon."

Kaldur set a reassuring hand on the doctor's shoulder, "We will protect you."

Roquette sighed heavily, then turned to the computer once again, "Tracking Fog now."

A few minutes later, I was patrolling the hallway outside the computer lab when I heard Artemis ogling over Superboy.

"Mmm, that boy."

"He can hear you." M'gann pointed out jealously, "We can all hear you."

"Oh, I know."

"Wildcat, Dr. Roquette has located the Fog in Philadelphia. You, Robin and Superboy need to stop it from stealing any more intel. Miss Martian, reconfigure the Bioship so they can pursue." Aqualad ordered. As I made my way outside, my comm rang in my ear.

"You've got Wildcat." I greeted whoever was calling me on a private line.

"Kara," It was Kaldur, much to my surprise, "Report to me when you arrive in Philadelphia and notify me when the Fog has been neutralized."

"Will do. And don't worry about us, we'll be fine." I answered with a smile, even though he couldn't see it.

"I would not be doing my job as leader if I did not tell you to stay safe." A blush crept on to my face as I was joined by Robin. I switched to the telepathic link.

"Don't underestimate the Shadows, Aqualad. They're capable of just about anything, and they aren't afraid to get their hands dirty to get the job done. Be ready for anything and everything."

"Understood. Now go!" Kaldur replied, as Rob and I boarded the Bioship with Superboy. I took the helm and we began to make our way to the City of Brotherly Love.

Philadelphia

August 8, 22:39 EDT

When we arrived in Philadelphia, Robin was able to locate the Fog's target: S.T.A.R. Labs. But when we arrived, it was completely destroyed. I was taken aback by the amount of destruction that the Fog had caused. A mountain of rubble was all that remained of one of the most advanced science facilities on the East Coast.

"Wildcat to Aqualad. We're over Philadelphia and we've located the Shadows target: S.T.A.R. Labs. We're too late. It's been decimated. This is bad, S.T.A.R. Labs is cutting-edge science and tech, and now it's in the hands of the Shadows... what's next?" I asked quietly.

There was a brief pause before Kaldur responded.

"Dr. Roquette is scanning for the Fog again. We will send you coordinates as soon as we have them."

"Roger that, Wildcat out."

Robin tapped away at his wrist computer while Superboy sat in silence. Moments later, an alert appeared on the Boy Wonder's wrist.

"Got the coordinates for the Fog. Let's just hope we're not too late."

The next target came as a shock not only to me, but to Robin as well. It was a Wayne Tech building. Of everyone on the Team, only Wally and I knew who Robin really was. Richard 'Dick' Grayson, ward of Bruce Wayne, aka Batman.

"The next target is a Wayne Tech facility. In theory, its system's software could be used to hack the-" Robin hesitated. I knew that the Wayne Tech software was connected to the Batcave and by extension, the Justice League computer. But Superboy didn't.

"The what?"

"That doesn't matter, right now." I answered for Dick, "What does matter is that Wayne Tech operates a 24-hour work force. We'll never be able to evacuate everyone in time!"

"Receiving the virus now! If I can get access to one of the Wayne Tech computers, I can shut down the infiltrators." Robin said. Superboy's eyes narrowed as he focused on a figure sitting in a van in the parking lot below us.

"Don't need the virus." The clone replied, jumping down to the lot and charging the figure, who from my point of view looked like Professor Ojo.

"Superboy! Wait!" I yelled as I tried to stop the clone. I groaned as I watched the Fog fly into the building and turned to Robin, "Get inside; shut down that weapon!"

"On it." The Boy Wonder nodded as he leapt down and took off toward the building. After a few minutes, I got a call from Robin over the comm link, "The infiltrators have been outfiltrated."

I rolled my eyes and sighed, "Nice wordplay there, Bird Boy. Now, hurry up and get back out here. Superboy is beating the crap out of Ojo; I'll need your help to reign him in."

"On my way out."

I leapt down onto the concrete and pressed my fingers to my comm to call Kaldur, "Wildcat to Aqualad. The Fog has been neutralized. We'll be back soon."

"Good. We encountered an assassin, but the doctor is safe, as are the others." He answered me. I smiled lightly as I approached Superboy, who had finally released Ojo. Robin joined us as I finished my conversation with our leader.

"We're on our way. We'll meet you back in the Cave."

"Of course. We will be waiting. Aqualad out."

Mount Justice

August 9, 23:16 EDT

When Robin, Superboy and I returned to the Cave, Batman was there to greet us. We reported what had happened in Philadelphia and he dismissed us for the night. As I was about to head to the zeta tubes, dressed now in civilian attire, my phone vibrated in my back pocket.

From: Dinah

Ollie and I are stuck at charity dinner. Won't be back until around 2, spend the night at the Cave. Don't want you going home alone.

I chuckled as I read the message. I found it funny that my mentor thought that I wouldn't be safe walking back home from the zeta tube in Star City, but she had no problem with me going hand to hand with a Kryptonian. But I knew better than to argue with her, so I turned on my heel and walked back to the common area, where M'gann and Superboy were channel surfing.

I set myself down in a chair and waited for them to pick something to watch.

"Aren't you going back to Star City, Kara?" Superboy asked with an arched brow.

"I was, but something came up and Black Canary wants me to spend the night here. Luckily, I already have a room set up here for situations like these." We all had bedrooms in the Cave for late night missions and in case of emergency situations. And frankly, since I sat down, a rush of tiredness fell over me that prevented me from even considering returning to Star.

"In fact, I'm going to head to bed now. It's been a long night. I'll see you guys in the morning."

I was almost to my room when I turned a corner and crashed into Kaldur. Embarrassment fell over me as I realized how stupid I probably looked.

"Sorry, Kaldur. I didn't see you."

"My apologies, Kara. But I thought you had returned to Star City." He said, a bit distracted. I could see in his pale green eyes that he had something on his mind. Something was troubling him.

"Yeah... Something came up, so I'm spending the night here... Are you alright? You seem distracted." I asked, concerned. He gave me a false smile.

"Yes. I've just been thinking about a lot of things lately. It's nothing you need to worry about." He dismissed. He stepped past me and as he turned the corner said, "Good night, Kara."

And then he was gone.
