Hidden Angel Chapter 1

I ran down the dark hallways clumsily, only slowing when I stumbled on my own feet. My hand clutched my side and I could feel a warm liquid trickling from in between my fingers. My energy reserves were depleted but I still focused on healing the wound that I had received during my fight to escape. My healing powers worked quickly, but unless I got some rest, it wasn't going to heal any time soon. My breaths were painful and ragged, with every passing moment it was becoming harder to breathe. I was on the brink of consciousness, my eyelids felt heavy, and my head was pounding, but I couldn't stop. They were still after me. Even now I could hear their footsteps coming closer. I forced myself onwards and trudged down the gloomy corridor. My wings were worn out, splattered with blood and missing quite a few feathers. Yeah, my WINGS. Long story short, I think I'm somehow genetic cousins with a bird and I've been like this for as long as I can remember, which isn't very long, and I don't know who I am and blah blah blah. I'm special in a few more ways than just that though but that's a story for another time.

I turned a corner and a huge hall opened up in front of me, the walls lined with pods containing glowing creatures that seemed to be generating electricity and powering the whole place. A quick scan showed that there was no one else in the room but there was a huge set of metal doors on the other side. 'Maybe thats an escape route!' I stopped gawking and focused, and with newfound hope of escape pushing me on, I limped towards them and frantically searched for a control panel.

After searching for a good 10 minutes and having unsuccessful results, I let out a small sigh and slumped against the wall in defeat. As I focused more energy to healing my wound, I assessed my chances of survival in this situation: I was being chased by evil scientists who wanted me strapped into a cloning machine to find out what made me tick, I was pretty sure I could've saved about 10 peoples lives with the amount of blood I've lost in the past few minutes, no thanks to those geno's that attacked me, and I'm trapped 20-30 levels below ground in said scientists evil lair with all my hopes of escape pinned on the rare chance that some one would forget to lock a door. Yeah, it didn't look good for me. I needed a miracle to get out of this, but with my luck, I'll probably get a security camera blaring alarms in my face.

I realised how exposed I was and got up shakily. The gaping hole in my side had closed a little and the blood was slowing, but I wasn't sure if that was because my powers were working or because I was running out of blood. I edged/limped towards a pod, tucking myself neatly behind it but making sure I had a good view of the doors and waited for a chance to escape. 'I don't want anyone coming through those doors and spotting me' I thought to myself.

After a few minutes, the metal doors parted to reveal a tall geno. I knew I would have to wait for another opportunity because he wouldn't leave the doors open long enough for me to get through. If he saw me he'd alert every genomorph in the premises and I wold have no hopes of getting out, but I'm not sure how much longer I have before someone else finds me.

I squirmed further back, trying to make sure he didn't see me. Luckily, the blue-skinned creature seemed not to notice my presense behind the pod, and walked straight past and out the doors I had come through.

I let out a breath I didn't know I'd been holding and calmed myself down. I pulled my hand away from my wound as it was barely bleeding now and peered out of my hiding place. I was about to step out of my spot behind the pod when the doors were wrenched open and three teenage boys walked through. I shuffled back and questions were already forming in my mind. 'Who are they? How did they get all the way down here? And what's with the spandex?' I pressed myself back into the cramped space and now focused the energy to my tattered wings. They were my fastest route of escape, so I needed them as healed as possible.

The three teens were all in weird outfits and two of them had masks on. There was a red haired boy in yellow and red outfit who was wide eyed and stunned at the sight before him. There was another boy, who had a calm aura surrounding him, that had tattoos running up his arms and two hilt-like things sticking out from his back. And lastly, there was a black-haired boy with a cape who looked the same age as me. He was kneeling down beside a computer terminal frowning at a screen, and he looked like he was trying to hack into the system mainframe.

'Pft, good luck with that.' I thought. I had already tried to get through a terminal, and I got barely anything except from basic stats on the geno's; which I found out anyways when I fought them. All of their long-term goals and projects were heavily protected so I didn't find out anything useful.

I normally would've listened in on what they were saying but I didn't think they'd find anything new so I didn't bother. Until I heard "Project Kr." I froze. I couldnt get anything on that, exept from the name, those were the most heavily protected files in the system. I strained my ears to hear what the black-haired boy was saying. "But the files are encrypted, I can't..."

"Don't move." the three teens turned and I followed their gaze to see a man dressed in blue and gold standing infront of a whole bunch of genomorphs that were poised for attack.

Well this wasn't going to be good.

Robin's POV

"What? Robin? Aqualad? Kid Flash?"

"At least they got your name right." I muttered.

"I know you, Guardian, a hero." said Aqualad.

"I do my best." Said Guardian.

"Then what are you doing here?" asked KF.

"I think that's my question boys," Guardian replied "I'm chief of security, you're trespassing. But we can call the Justice league, figure this out."

"You think the League's gonna approve of you breeding weapons?" shouted Kid Flash.

"Weapons? What are you-, what have I-" Guardian clutched his head for a moment and the small geno on Guardians shoulder glared at him as it's horns began to glow. "Argh, my head!" The moment passed and Guardian shouted a command at the geno's surrounding him "Take them down hard! No mercy!"

Sakura's POV

The geno's spread out and leaped at the three boys, but the caped one threw down a smoke bomb and they headed for the doors on the other side of the room, which happened to be an elevator. 'How could I not notice that! More importantly, I need that ride now!' I thought desperately. I tucked my wings in so no one could see them and scrambled out of my hiding space. With super speedy legs, that could've won gold on sports day if I had ever had one, I sprinted towards the doors, but came face-to-face with a growling geno.

"Woah!" I squeaked as I came skidding to a halt just in front of it. Some of the other geno's heard me and bounded over, and by now Guardian and the three boys had noticed my presence too.

"She escaped? Geno's, capture and retrieve the escapee alive!" Guardian commanded. I swore under my breath as a geno sprung up and swiped at me. I ducked and rolled away but it's claws scraped along the flesh of my arm. I was still not at my best and it was showing. Deciding against fighting my way through the pesky creatures, as I had done previously when there were a lot more, I dodged another swipe and jumped into the air, flipped and gracefully landed in a crouch behind the geno's that were previously blocking my path to freedom. I got up and sprinted towards the elevator like my life depended on it, which it probably did. The three boys were staring at me wide eyed and jaws dropped by the lift doors now that they weren't the focus if the attack.

I practically screamed at them "What are you waiting for, get us out of here!" The caped boy shook his head, opened the doors and all four of us dashed into the lift with the genos in close pursuit. I reached to press a random button on the panel, not caring where we went as long as it wasn't here, and wincing when I stretched my injured side. The caped boy beat me to it, but he seemed to know what he was doing so I let him. The doors snapped shut on the geno's and we were on our way to an unknown floor.

Robin's POV

For a while we all just lay there in an exhausted heap on the floor, catching our breath. I was slightly stunned at what had just happened; one minute we were facing a huge bunch of geno's, then the next we were watching an agile girl flip over them and throw us into an elevator. Luckily I had managed to press the right button in the chaos and we were heading towards Project Kr, whatever that was.

"Um... Could you let me up now?" My thoughts were interrupted by a small voice from underneath me. I looked down and saw I was sprawled on top of the girl from before. Now that I looked closely at her, she was quite pretty; she had waist length cherry pink hair which was partly tied back by a

yellow ribbon, huge sparkling blue eyes with little flecks of gold in them, and a shining silver locket around her neck. There was also a metal collar like thing around her neck, and I wondered what it was for. She was wearing a white, sleeve-less top with light pink edges and separate wide-ended sleeves that were just slightly too long for her arms, a just-above-knee-length orangey-yellow pleated skirt , tight black shorts underneath, and tight, brown knee-high boots.

"Uh, Hello? Anyone home?"Once again her words cut through my thoughts and I shook my head to clear them. "Uh, right." I practically jumped off her and looked to my left to hide the redness creepimg across my face.

KF and Aqualad were sitting up, rubbing their heads. They looked over to where I was and saw the girl. I nodded at them to silently say she was okay for now.

I looked back to the girl in the corner of the lift and saw she was struggling to stand. I offered her my hand, and she hesitantly took it, wincing as she did.

She shakily stood up, but collapsed almost immediately afterwards. I bent down to her level as Kid Flash and Aqualad came over to see what was happening.

"Are you okay?" Aqualad asked "What's wrong?"

She was breathing heavily, sweating and clutching her side tightly, which was covered with... blood. Her white top was drenched in the red liquid and it looked like she had been bleeding for quite a while.

"You're bleeding!" Kid Flash shouted "One second, I'm pretty sure I have something for you." He began to frantically search through his pockets and pulled out a lot of stuff; candy bars, energy bars, other weird kinds of bars, bananas...

'Where does he have room to keep this stuff?' I thought. Meanwhile, I looked into a pouch in my utility belt and produced some antiseptic and some bandages, but KF was still going through his pockets.

I turned back to her to see that her hand was glowing. She was still sweating and breathing heavily, but not as much now and the wound on her side seemed to be closing up slowly.

I gasped and the others turned and saw what I saw too. We all stared before Kid Flash shouted

"Wow! You have powers, and you can heal yourself? Awesome! Robin, I am officially whelmed."

The wound closed up almost completely and the girl slumped back into the corner, her energy drained. She looked exhausted and worn out, but at the same time, her eyes said she had some fight left in her.

I put away the medical stuff as Aqualad questioned the girl.

"Who are you? What are you doing here and how did you get so badly injured?"

The girl looked up and glared at us "Shouldn't you give your own name before asking for someone else's?" There was the fight.

"True." replied Aqualad "I am Aqualad, this is Robin and-"

"Hello beautiful, I'm Kid Flash" He took her hand in his and she looked slightly stunned as he continued. "I'm the fastest Kid alive. Wanna catch a movie later?" I twitched, sometimes that guy was really annoying, now was really not the time and she was obviously stressed enough, so how dare he- wait a minute, I barely know her, why am I getting so worked up over KF's usual flirting with her?

Aqualad pushed Kid Flash away from the girl, who wasn't quite sure what to say, and continued "We are here to investigate Camdus and their operations on behalf of the Justice League.."

"But so far we have had no luck." I finished. "Now your turn."

Her gaze softened and she pulled her legs up to her chest and rested her head on her knees. Sighing, she spoke softly

"You may call me... Sakura"

'Thats not her real name' I made a mental note.

"I'm also investigating Camdus, but for... personal reasons. I ended up in a fight with a whole load of geno's and was injured." she shifted her posture so that we could see the three pinkish gnash marks where a geno had clearly dug it's claws into her side.

"How many geno's did you fight?" I asked, still staring at the steadily healing wound. I wanted to know how strong she was: I figured a small girl like her, fighting those geno's that even we could barely defeat, would handle about 2 or 3 before she was completely overwhelmed.

"I don't remember exactly because I was fighting for around half an hour, but let's just say now they can't send re-enforcements."

My jaw dropped. I was doing mental calculations; in a facility this big, there must be thousands of genomorphs, and around half would be reserves. If she was being fairly accurate, she must have been battling hundreds of Genos to cut off their supply! Even if she wasnt accurate, she stiil must be able to defend herself pretty well to be wandering around the Cadmus premises long enough to get that deep underground. And she was fighting for half and hour? That requires a huge amount of stamina and technique. Also, when fighting those kind of opponents, there is no luck, so she must be a very skilled fighter, I'm surprised she's still conscious after undergoing that kind of mental and physical stress.

I was still wrapped up in my mental theories when Sakura continued "I was knocked out sometime during the fight and when I came to... I had this collar on." She seemed to be hiding something, she wasn't looking us in the eye as she said he last part and I knew she wasn't telling us the whole story, she was missing out something she didn't want us to know.

She pointed to the collar thing I'd spotted earlier around her neck and I noticed it had a few dents in it as she lightly tugged at it.

"What's it for?" asked KF curiously.

"It restrains my powers a lot, so it was hard for me to heal myself. It seems to be unbreakable and impossible to get off, I've tried everything. It looks like they thought that if they limited my powers, I wouldn't be a problem."

"Guardian said that you escaped, what exactly did you escape from?" I asked carefully. She had willingly given us the answers to all the questions we had asked, but I didn't want to push the borders of her cooperation.

"He must've ment escaping the lower levels." she replied a little too quickly, her eyes darting from side to side, she was lying again. "I knew I couldn't handle another bunch of geno's attacking me, so I tried to find the exit but I couldn't get out. And that's when I ran into you guys. So we better still be escaping."

Kid Flash glanced up at the level indicator to see where we were and Sakura did too, but I already knew where we were going.

"We're going down?" Sakura whispered.

"Out is up!" cried KF.

"Excuse me? Project Kr is down; on sub-level 52" I replied simply.

"This is out of control. Perhaps... Perhaps we should contact the league." said Aqualad.

The doors slid open and I jumped out.

"Well, we are already here." Pointed out Kid Flash.

We all got out, but Sakura was a little hesitant before leaving the safety of the lift. She hung back a little and twitched at every little noise.

"Where do we go now?" She asked.

"Yeah bizarre looking hallway #1 or bizarre looking hallway #2?" I replied.

"Halt!" we turned to see a tall blue skinned geno with big horns and wearing a white labcoat. He waved his hand at us and his horns began to glow, sending two gas canisters straight at us.

We ducked as they exploded on the wall behind us and I threw a disk at him, but it stopped right in front of his face and he sent another two canisters towards us.

Sakura wasn't very steady on her legs so as she tried to dodge the explosions, she was thrown to the floor, and struggled to get up again.

The geno sent a canister straight at Sakura and her eyes widened in fear as it flew at her. I leaped towards her, wrapped my arm around her waist and pulled her out of the way just as the canister exploded on the spot that she was until a moment ago.

"Thanks." she said, and I could almost hear her mentally cursing herself. I set her on her feet, grabbed her hand and followed the others who'd already started down one of the fleshy hallyways.

Normal POV

Robin and Sakura arrived at a set of metal doors that read 'Project Kr'. The doors had been jammed with a metal container and they squeezed through as Aqualad kicked it free, sealing them all inside.

Robin quickly fiddled with the control panel and announced that the door was disabled and that they were safe.

"We're trapped." Said Aqualad.

"But atleast theyre out there and we're in here" Sakura pointed out. She was looking a lot more stable now that she had directed her healing powers to restoring her energy and she was studying her surroundings.

"Um, guys, you should see this." said Kid Flash warily.

As everyone turned to see what he was talking about, KF pushed a button and a pod in the center of the room lit up to reveal a teenage boy in a white body suit inside. There were three small creatures positioned above his head aswell but most importantly, he had a big red S on his chest, and he looked just like a younger version of superman.

Kid Flash noticed the symbol on the pod and said

"Big K, little R…the atomic symbol for Krypton."

"Krypton? Does that mean..." Sakura didn't finish her sentence but everyone was thinking the same thing.

"Robin, hack." Said Aqualad.

"Huh? Oh, right." Robin hazily replied, obviously distracted. He plugged himself into the terminal amd began searching through files.

"Lets see.. Weapon designation 'Superboy'. Grown in 16 weeks! From DNA acquired from Superman." Robin explained in disbelief.

"More like stolen" added Aqualad.

"No way the big guy knows about this." Said Kid Flash.

Robin continued "It says here that his solar suit allows him to absorb yellow light radiation 24/7."

"And these.. creatures?" asked Aqualad.

"Genomorph gnomes…telepathic, force feeding him in education." answered Robin.

"You mean Cadmus are making their own mini superman? Creepy." said Sakura.

"They're making a slave out of, well, Superman's son." Said Kid Flash.

"Now is the time to contact the League." Aqualad decided.

The three boys tried to use their communicators but it was in vain.

"No signal." Announced Aqualad.

"We're in too deep…literally." Said Kid Flash. He glanced over his shoulder to look at Superboy. "This is wrong."

"We can't just leave him like this." said Robin.

"Set him free." said Aqualad.

Sakura just nodded slowly. She wasn't quite sure about this 'if the genomorphs are brainwashing him, wouldn't he be on their side?' she thought suspiciously. 'Oh well, if they think it's okay, then why not? What's the worst that could happen?'

Robin pushed a few buttons and the pod opened.

Cracking his knuckles, Superboy suddenly hurled himself into Aqualad, pinned him to the ground and started punching him.

Robin, Kid Flash and Sakura quickly ran over and tried to hold Superboy back.

"Hey, relax! We're on your side." Cried Kid Flash, trying to pull him away from Aqualad.

Superboy swung round and punched Kid Flash, sending him flying into and through a large glass tube, and it shattered upon impact.

Sakura gasped, and seeing an opportunity, Superboy swung round the other way and sent Sakura into the metal wall with a loud 'crack'.

"Sakura!" Robin shouted, flinching at the sickening sound of her ribs breaking upon connection with Superboys fist.

"I didn't want to do this." Said Robin. He set off a gas grenade in Superboy's face.

Superboy stumbled backwards, coughing and tried to clear the air by waving his hands infront of his face. Aqualad got up and kicked Superboy into the terminal by his pod.

Robin pulled out his taser gun thingy and fired at Superboy. The wires stuck to him and started to send and electric charge towards him, but he ripped them off and pulled Robin towards him. Grabbing Robin, Superboy flipped him, threw him to the ground and pushed down on his chest hard with his foot. Robin struggled under the pressure but to no avail.

Sakura pulled herself off the ground and groaned when she found that the wound on her side had opened again and she now had two more broken ribs making five just today, three more and it'd be a personal best.

She looked up to see Robin pinned to the ground by Superboys foot and rushed over to help. Aqualad was quicker though and he formed a hammer with his hilt like weapons and smashed Superboy off Robin. He tried to help Robin up but he clenched his chest and passed out.

Now It was just Sakura and Aqualad left facing Supermans clone.

Superboy moved towards them as Aqualad shouted "We are trying to help you!"

Superboy picked up speed and ran straight at Aqualad, who managed to dodge in time and tackle Superboy into the wall. He pulled his arm back to hit him but Superboy grabbed Aqualad's fist and pushed him off.

Sakura ran over as Aqualad grabbed Superboy from behind, and Superboy jumped up to the ceiling in an attempt to knock Aqualad off. Superboy smashed Aqualad into the ceiling twice before he lost consciousness.

Sakura was the last one standing, and she was terrified, but she didn't show it. She decided that she didn't have enough energy to use her powers so she resorted to taking up a defensive stance. Superboy turned to her and charged, his fist clenched and ready. When he got close enough, she ducked under his arm with lightening speed and threw a strong punch from his blind spot. It hit him right in the side of his face and he staggered sideways.

Sakura resumed her defensive stance and glared at him, daring him to attack. Her side was drenched in blood and she couldn't move properly because of the broken ribs, so they were both confused as to how she landed a hit on him.

Superboy shook his head and charged at her once again, but this time he was closer. Sakura miscalculated her timing, so his fist connected with her shoulder, even though he was aiming for her head. She cried out in pain as the same shoulder slammed into a metal wall on the other side of the room and she fell to the floor, unconscious.

Superboy walked over to the door Robin had locked and flung it open with brute force.

A man dressed in a white lab coat stood in the doorway. He glanced at Superboy as he walked in and noticed his bruised cheek. He looked around the room, noting the four unconscious teenagers. He walked over to the girl and kicked her in her bleeding side.

"I told you that you couldn't escape." He smirked to himself.

A/N Ooooo... Sakura's hiding things from the team! What's she hiding? I'm not going to tell you! Muahaha!

So... how was it? Please tell me; to long, to weird, not making sense, just tell me! I'm new to the whole FanFiction thing, I only started reading a few weeks ago '_ Constructive criticism welcome, I want to know what I need to work on. I've already typed up the next chapter but I can change it!

I don't know how often I can update, but I'm sure it'll always be on a weekend, I'll probably post the next chapter next weekend.

Please R&R, the button isn't evil... at least not the last time I checked.

SakuraTenshi out!
