AN: Hey all, there was a great response to the last chapter, and so I am back with an update. I was originally supposed to be updating my PJ/ RWBY story but got stuck at the halfway mark as I have written myself into a corner, hence why I decided to bang this out instead.

Hope you all enjoy and leave a review.

Warning there is a longer than usual AN at the bottom, I kind of went on a ramble.

Disclaimer: I do not own Percy Jackson or the DC verse.

(Last Time)

Aqualad, Kid Flash and Robin eyed Percy curiously at that, but said nothing more about it. As Aqualad instead looked down at the unconscious Guardian and then over to Superboy, the strongest one here, he presumed. "Hey Superboy, can you carry Guardian out of here? We can't just leave him here."

"Don't tell me what to do!" Superboy growled in response, still obviously a little leery about this whole alliance thing. After all, although he wanted to be like his originator Superman, he was still a bit cautious about helping these sidekicks, and that bastard he had just had a fight with.

Despite that though, he still bent down and lifted the injured and unconscious Guardian up, and carried him on his back as the group left the room. With Robin pausing long enough to throw a few explosive disks back at the cloning tubes, destroying the machine, and any DNA samples they might have collected. It was just a pity that that Desmond guy had escaped during all of the chaos.

Chapter 3

(In the depths of Project Cadmus)

Running back through the sublevels of Project Cadmus, the group made a particularly odd site as the three costumed sidekicks ran at the front of the pack, leading the way back to the elevator shaft, and freedom. With the Superman clone, amusingly named Superboy, running closely after them, the unconscious form of Guardian slung unceremoniously over his shoulder, as he used his super strength to half drag, half carry, the unconscious, brainwashed Hero after them.

After which Percy brought up the rear, his Drakon bone sword in hand as he padded along after the rest of the group, allowing them to direct him, as they likely knew just as much about the layout of the floor as he himself did. With Percy instead busying himself by fending off the many genomorphs that were swarming around them. The creatures having all been alerted to their presence by the alarms, and then sent to pursue them, no doubt by the escaped scientist, Dr Desmond.

Thus far the group had managed to keep ahead of the swarm of genomorphs though, all of them moving rapidly through the fleshy corridors, even as more and more of the horned, grey skinned creatures erupted from glowing, red bubo like tumours on the sides of the wall. Forcing the group of five to defend themselves, as Robin pulled out an extendable staff, smacking and thwacking away at any grey creature that came near. Whilst Aqualad used his water bearers to create hammers out of water, even as he smashed anything that got in his way, out of his way. Kid Flash meanwhile rushed ahead, a red and yellow blur as he punched and kicked any of the creatures that got near him.

"Here hold this." Superboy suddenly grunted, as he thrust Guardian's heavy body over to Percy, making the Demigod grunt at the sudden weight, even as he had to angle his sword away so it didn't accidentally impale the unconscious, brainwashed Hero.

"Hey!" Percy shouted in irritation, even as he saw the clone turn and leap at a group of giant, gorilla like genomorphs that got in their way. The sudden impact of his charge causing them to pause long enough for Superboy to smack two of them and send them crashing into the side of the corridor, before he was hit by the third.

"Superboy we are trying to escape, not bring the building down on us." Aqualad shouted as he turned and saw what the clone was up to.

"You want escape!" The clone shouted back before he threw the last behemoth into the other two that were just starting to get up, after which the clone began to run towards them.

"Duh dumbass, that's the whole point." Percy grunted, before he threw Guardian back at Superboy, making him blink in confusion as he caught him, only for Percy to leg it to the elevator. "Back to you."

"Oi!" Superboy shouted only for Percy to ignore him, as he instead swung out with his sword, cutting down three of the humanoid genomoprhs, before he ripped the blood from one of the bodies, forging it into a bloody spear of ice as he did so, after which he then hurled it at one of the behemoth like creatures that were lumbering after them.

The spear stabbing through one of the genomorph's red eyes and causing to lurch backwards, thrashing as it did so, even as it crashed into some of its fellows in a chaotic mess of thrashing, spasming limbs.

"Now come on." Percy barked over his shoulder at Superboy, not waiting for a response, as he instead just turned and ran around the corner to where Kid Flash and Aqualad were forcing open the doors to the elevator shaft.

"Don't tell me what to do!" Superboy shouted after him, not that that stopped him from following, as he dragged Guardian after him.

"He's like a bloody broken record that one." Percy grumbled, wiping the creature's dark red blood off of his sword, not missing as he did so the wide eyed look of disgust on the Robin's face, or the discomfort that showed in both Aqualad and Kid Flash's expression. No doubt they would whine at him about unnecessary force later, but for now there were other things to worry about. "Now come on, let's get out of here."

With that said Percy sheathed his sword and then jumped through the now open elevator doors, after which he landed on the other side, his hands digging into the metal with a hissing sound, the metal warping under them, even as he began pulling himself up, leaving steaming handholds behind him as he did so.

Seeing this Robin grabbed the Kid Flash and then used a grappling gun to follow as he shot up into the shaft, rapidly passing Percy by as he continued to climb, using both his enhanced strength and a particularly corrosive poison/ acid he was exuding from the pores of his hands to warp the metal enough to climb.

Something which Aqualad took advantage of, even if he wasn't sure how his temporary teammate accomplished the feat, as the dark skinned teen cloaked his hands in water, the tattoos on his arms glowing blue, before he then used the still smoking handholds Percy had created, the two of them quickly ascending up the elevator shaft.

Seeing his fellows already moving up, Superboy grabbed Guardian, before he too leapt through the elevator doors and flew upwards, or rather he tried too, because as Percy and the others ascended, they heard him let out a loud shout as gravity took hold and he began to fall.

Not that he fell too far, because as he reached the peak of his jump, just a little below Percy and Aqualad, Robin then shot out another grabble hook, catching the duo before they could fall too far.

"Superman can fly; why can't I fly?" Superboy asked dejectedly into the slight silence that followed.

"Don't know, but it looks like you can leap over giant building with a single bound, still pretty cool." Kid Flash praised, trying to be comforting, with Superboy ignoring him as he instead quietly thanked Robin for the save.

Before anymore could be said though, the group in the elevator shaft, suddenly heard an ominous sound above, a rushing sound of metal on metal. The source of which rapidly became apparent as they looked up to see that the elevator was heading right towards them.

"We need to get out of here, now!" Aqualad shouted, even as Percy pushed off from the side of shaft, scrabbling slightly as he found purchase on the ledge opposite him, before he pulled himself up and then forced open the door to the nearest floor level open.

"That's a good shout, now come on." Percy grunted as he did this, gesturing as he did so for the rest of the group to follow him. Not that he needed to, as by that point they were all in the midst of doing that, piling in on him and nearly knocking him onto his arse as they all quickly jumped through the open door and just narrowly avoided getting squashed by the speeding elevator.

Of course they weren't given long to recover from this, before once again a group of genomorphs spotted them and quickly gave chase. Forcing the group to get up and rapidly head off, Percy and Superboy taking the lead this time, whilst the other three covered their backs.

"Turn left, left!" Superboy shouted suddenly as they ran, with them instinctively following his lead. "Now right." He said once again only to lead them to a seemingly dead-end.

"Great directions Supey, are you trying to get us re-podded?" Kid Flash yelled out nervously as he saw their predicament they were now in, the sounds of their pursuers sounding out loudly behind them, which just made Superboy lower his head in confusion

"It's a dead end, we'll need to fight our way out." Percy spoke up next, already drawing his sword as he shifted his legs into a ready positon, preparing to lunge forward and into the fray at any moment.

"No stop, we don't need to fight, this is exactly what we needed. Everyone, get into the ventilation shaft." Robin interrupted, his eyes flicking over to Percy as he lowered his sword, even as he then pulled off the ventilation shaft cover overhead.

"Spoilsport." Percy grumbled, sheathing his sword again, before he moved back to help his fellows up and into the ventilation shaft.

"Wait, Guardian is too big to fit!" Aqualad suddenly interrupted as he, Superboy, Kid Flash and Robin got into the overhead ventilation system, only for them to then realise that the bulkily built Guardian was too wide to get through the narrow vent.

"You lot go, I'll take Guardian and find another way." Percy decided, grabbing Guardian as he did so, before he slung him over his shoulder and drew his sword.

"We can't just leave you behind." Aqualad said, shaking his head as he made to get down.

"Well you're going to have to." Percy said with a shake of his head, "Now go, I'll need as much time as I can get, to get away."

"Aqualad, come on we can't let him do it alone." Kid Flash said, shaking his head as he did so, before he struggled to get passed the dark-skinned Atlantean.

"You're wasting time." Percy replied quickly, shifting Guardian's body around on his shoulder as he did so, freeing his left hand so that he could raise it, and also so he could make the pipes above, those attached to the sprinklers, explode. Covering the area in water as he did, before with a slight amount of exertion and a wave of his free hand he froze the walls and roof around him solid, blocking the young heroes from getting out.

This didn't stop them from seeing him though, as he instead raised two fingers, and then gestured for them to 'fuck off', before he ran off himself.

"What just happened?" Robin demanded of the two behind him.

"I don't know, but Percy has taken Guardian and run, and has frozen the airshaft shut." Aqualad replied, musing as he did on just what Percy's abilities actually were, after all he could apparently control water, ice and acid.

"Damn, well we can't wait around." Robin grunted, looking at his wrist computer as he did so, even as he internally cursed losing track of the wild card in the group, Percy. "The guy seems tough enough, I'm sure he'll meet us up there."

"Robin is right, we should take advantage of the distraction Percy has made and get out of here. Once we do so we can contact the League for help and then go and save him. We can't let his sacrifice be in vein." Aqualad spoke up again, looking at the others as he did so, before he gestured for them to start moving.

(A little while later, with Percy)

"Dammit, this was a mistake." Percy grumbled to himself as he dragged Guardian through the much more normal, and clinical looking corridors of the upper levels, the water pipes overhead exploding as he did so, continually showering both himself, and everything else in water as he ran for the staircase.

Keeping his sword sheathed and his grip on the large, helmeted man tight, Percy had to rely on his hydrokinetic abilities as he sent blasts of water out at any genomorph that got close to him. His whips and blades of water, cutting through their flesh as he used just a single hand to mould, solidify and manipulate the falling water.

A few years ago, when he first started out as a Demigod on his first couple of quests, such a level of control would be beyond him, back then he relied on just throwing out the occasional wave when he could and then either legging it, or using his trusty sword, Riptide. Now though, after training his abilities, and honing them in his many battles, against a whole assortment of Titans, monsters, Demigods, gods and giants, and his journey through Tartarus, such a level of control was almost simple.

More than that though, he had also begun to expand on his skillset, pushing himself beyond the limits as he sought to not only master his abilities relating to his father's domain over the sea, but also his domains of earthquakes and storms. With his confrontation with Ahklys in the depths of Tartarus having opened his eyes to his own potential, as he pushed past the limits he had created for himself.

It had gotten to the point at which he could not only release seismic waves through either the ground or the air, but could also absorb and focus that power, which in turn allowed him to manipulate vibrational waves from his hands and feet.

On top of that with his water he could not only draw it from the air or living things around him like trees and plants, negating the need for a large water source, but he could also freeze it at will, or make it boiling hot. He could even turn it into steam and manipulate that, or change the water's PH balance, which he had found out when he explored his Toxikinesis ability, the one he had discovered courtesy of the old misery guts herself, Ahklys.

But he had in fact gone beyond that, as he discovered he could also manipulate the water in a person body. He could contract the blood vessels in someone's brain causing a debilitating headache, he could starve the brain of blood causing temporary unconsciousness, he could even restrict someone's muscles, paralysing them for as long as he maintained control. Then again he was still learning new things in regards to this ability, as he had found the Superman clone's blood all but impossible to control, though whether this was due to his physiology, his raw strength, or other factors, Percy wasn't sure. After all thus far he had only used it on normal, mundane mortals, he hadn't tried it on anything supernatural, or alien.

In fact the only domain Percy hadn't had time to experiment much with was storms, that being said, through that domain he had found himself capable of very limited Aerokinesis and Electrokinesis. Abilities similar to the ones his frenemy Jason had possessed, even if they were much, much weaker that the son of Jupiter's. Still he had them, he just needed the time to test them out, and to experiment with what exactly he could do with them.

Shaking off these thoughts, Percy continued through the flooded corridors, noticing as he did so that the place was noticeably empty of both genomorphs and people. The sight of which made Percy ponder whether he was even being pursued anymore? Or whether they were chasing after the Superboy clone to the exclusion of all else.

Not that he was about to complain, not when he made it to the staircase and began ascending, thus far avoiding pursuit. Though from what he could hear further up the staircase and the shouts and shrieks that echoed downwards towards him, his companions were not as lucky.

"Come on then Guardian." Percy grumbled, pulling the large man after him and wishing as he did so that he had super strength, as his arms were beginning to ache. After all he might be stronger than most mortals, strong enough to carry a full grown man, but he was no Hercules, as unfortunately not all Demigods were born equal. Just look at his friend Frank's abilities. Still the abilities he did have were nothing to turn his nose up at. "I really shouldn't have hit you as hard as I did, I mean if I knew I would be carrying you I would have just give you a tap. Then again you were kind of the bad guy so…."

Despite that though he couldn't help but grumble about it as he carried Guardian up the stairs. He had once held up the very sky itself for fucks sake, sure it had been for under a minute, but it was still quite the feat and had, at the time, made him ponder whether he did indeed have strength comparable to that of a god, or of Atlas the Titan of Strength and Endurance. Unfortunately though that feat was about more than raw strength, after all both Luke and Annabeth had held it for longer than him, and neither of them had been as strong as him, or even that much stronger than a mortal in peak physical condition.

Letting out another sigh as his thoughts began to wander, Percy continued heading up the stairs, his sword once again in hand as he found himself finally meeting resistance, which annoyingly enough came at a time in which he wasn't in a corridor flooded by sprinkler water.

Raising his sword, Percy made swift, economical slashes as he took the steps one at a time, keeping his balance despite the body of Guardian as he cut the grey creatures down at the legs and knees, and then finished them off by ramming the spiked crossguard of his sword into their bodies, or crushing their chests underfoot.

"You are really not making this easy." Percy growled up to the still unconscious Guardian, a few minutes later as he climbed over the last of the dead and dying genomorphs, making it to the top floor now, leaving behind a trail of nearly fifteen grey skinned bodies as he did so.

"And done." Percy cheered a few moments later as he burst through the door at the top of the staircase and hurled Guardian off of his shoulder and onto the ground, ignoring the loud thudding sound he made as he did so, Percy's sea green eyes instead moving off in the direction of some nearby fighting, no doubt it was his companion at work.

"Nearly there." Percy sighed again, before he grabbed Guardian by the ankle and dragged him after him as he headed towards the fighting, absentmindedly using his razor sharp, bone sword as an impromptu cane as he ascended one more level.

A few minutes later when Percy finally did make it to the source of the fighting, and into a much larger room he found himself pausing again as he took in the site in front of him. First off Robin, Aqualad, Superboy and Kid Flash were all present, each of them darting around the room as they fought their enemy.

The enemy in question being some nine and a half foot tall monstrosity, with glowing red eyes, mottled greyish blue skin and large bulbous muscles, more grotesque than that though was its face, upon which Percy could still spot the remnants of what looked like skin on the creature's body, including a stretch and ripped face that covered the creatures own.

"Well shit, it's a real life Leatherface." Percy mused, pausing for a moment to take it in before he once again dropped Guardian. They were on the home stretch now and Guardian was as safe as he was ever going to be.

"Percy!" Aqualad shouted as he noticed Percy's arrival, even as the four of them dodged and weaved around the attacking Blockbuster, formerly known as the Chief Scientist of Cadmus, Dr Desmond, before he drank one of his own solutions to 'get the power he would need to bring order to Cadmus'.

"Waterboy, Speedy, Capelad." Percy greeted, nodding his head with a grin as he deliberately got their names wrong, for no other reason than because he was bored and feeling a little irritable.

"It's Kid Flash!" Kid Flash retorted as he blurred around the room, bouncing off of pillars as he avoided the creature's charge and arm swipe.

"I think he already knows that, he's just trying to break the tension." Aqualad replied as he backed away from Blockbuster, even as he gave up on chasing Kid Flash and instead got into a tussle with Superboy, both of them punching and kicking each other, with Blockbuster taking the advantage as he landed a blow to Superboy's chin, one which sent him smashing into a nearby pillar.

"Awesome, well he could help instead you know!" Kid Flash replied sarcastically.

"Percy, Aqualad, Kid, keep ugly busy. I need a few minutes to come up with a plan." Robin, the youngest of the group shouted out from where he was crouched behind a pillar further down the room.

"Sounds like fun." Percy shrugged, before he ran at Blockbuster, his sea green eyes locking on the much large beings limbs as he closed in.

"Be careful, he's strong enough to throw Superboy around, he's not someone you can beat with brute force!" Aqualad called after Percy as he saw the older, darker haired boy charge in.

"Noted." Percy replied as he saw the creature lunge for him, his eyes narrowing as he stepped in, his sword raised and at the ready, even as his other hand came up gripping onto Blockbuster's wrist.

After which Percy twisted his wrist and pulled, tugging the much larger, stronger foe off balance, mid lunge, for a moment as he tried to finds his footing, even as Percy darted forwards, lunging forwards with his sword as he thrust it upwards and into Blockbuster's torso. The blade piercing the creature's blueish grey flesh lower down than Percy had aimed, but still causing some internal damage, even if the blade missed the heart and lungs.

Letting out a roar as the sword impaled him, Blockbuster suddenly twisted, his other leg coming up, before he landed a knee into Percy's side. The blow lacking his full power as he was off balance, but being enough to knock Percy away and to one side, despite the Demigod having tried to block with his right arm,

Rolling with the blow, Percy growled as he thrust his hands up and sent out a seismic wave through the air, the sudden wave of vibrational energy hitting Blockbuster head on and knocking him off his feet as it sent him smashing into a nearby pillar, shattering the pillar as he did so.

"Ouch, that hurt." Percy grumbled as he forced himself up, pulling water from the air as he did so, before he then shrouded his hand in it even as he put it over his aching ribs, the water quickly going to work as it healed his aches and pains.

"Dude you just stabbed him, and you're the one complaining about being hurt!?" Kid Flash shouted as he stopped and stared at Percy, even as Superboy let out a roar and tackled the now wounded and bleeding Blockbuster.

"Well it's a sword, that's what it's made for." Percy replied glibly, as he dismissed Kid Flash and instead turned to face Blockbuster. "Besides I missed, I was aiming for the heart. If I had struck true the bastard wouldn't have managed to get that blow on me. It's was a stupid mistake on my part, it's been a while since I last fought an opponent that big and I misjudged."

"Wait you were going for the kill? Dude we're Heroes we don't just kill the bad guys!" Kid Flash said in shock, his attention fully on Percy now.

"What you don't kill monsters?" Percy asked a bemused look on his face. "Hmm, I suppose most of the Heroes here are different than the ones I know."

"Clearly, but for now we should aim at incapacitating Desmond, and doing so in a way that doesn't take his life." Aqualad cut in, not wanting to get caught up in an argument about ethics with their new companion, not when they were in the midst of a fight.

"Well if you want." Percy shrugged, not really seeing what their problems were. Then again most of the enemies he fought regenerated in Tartarus, and the ones that didn't, well he had been at war at the time and sometimes causalities couldn't be helped.

"Yeah! Now everyone listen up, I have a plan!" Robin cut in, his gaze flicking over to Percy for a moment before it went back to Blockbuster when he saw the angry Superboy getting punted into a nearby wall. "We need to aim for the pillars and bring the roof down on him, now I have a plan for how to do this."

"You do that." Percy nodded, before he ran at Blockbuster, his gaze on the sword that was still in his side, the sword now probably stemming the blood flowing from the wound. "I'll keep it busy."

"Wait!" Robin shouted, irritation lacing his voice now.

"No, leave him. He makes a good point, he'll keep Desmond busy whilst we enact your plan, Robin." Aqualad interrupted getting a nod from both Robin and Kid Flash as he did so, even if Robin looked a bit irritated that Percy wasn't listening.

Likewise Superboy also got up and followed Percy's lead, throwing himself forward with a yell as he once again rushed the large, bluish grey skinned, former human.

Ignoring the yell, Percy released vibrational waves from the soles of his feet, blasting himself forward far faster than he usually would be capable of, even as he drew on the surrounding water in the air, forming a layer of water around his finger before he froze it, creating claw like gauntlets.

Following on from that Percy then crashed into Blockbuster, one of his fists smashing the larger being into the face, discombobulating him and knocking him backwards, even as Percy wrapped his other hand around his throat, his ice claws piercing the flesh. Before with another thought the ice melted, and became liquid, even as it suddenly became poisonous, the flesh around the claw wounds rapidly beginning to bubble.

Screaming in agony, Blockbuster grabbed Percy by the arm and threw him away with pure brute force, his other hand clasping his throat, even as his genetically altered body attempted to fight off the poison flowing through his system.

It was a fight he was losing though, because even as he scrabbled at his neck, his veins were visibly beginning to darken, and his scream of pain were turning into a lowly raspy gurgle as he struggled to breathe.

"Hyah!" Superboy roared as oblivious to this he smashed into the slowly dying Blockbuster, sending him hurtling backwards into another pillar, breaking it as he did so and causing a portion of the roof above them to collapse, trapping Blockbuster's legs under the rubble.

"Superboy keep destroying the pillars!" Robin shouted from a few metres back as he and his two companions broke off, only for them to pause when they saw Blockbuster's weakly twitching body and the bubbling, melting skin around its throat.

"I don't think that will be necessary Robin." Aqualad spoke up calmly as he lowered his arms and approached Desmond's gurgling, broken form.

"What did you do?!" Robin shouted as he looked between the startled Superboy and the dismissive Percy, who even now approached Blockbuster and pulled his sword out of its gut, with a wet sucking sound, releasing a sudden flow of blood as he did so.

"I slew a monster." Percy shrugged, before he raised a hand and pulled Blockbuster's blood off of his sword with his hydrokinetic ability, frowning slightly as he found the dark crimson liquid harder to control than a normal humans, once again it seemed he needed to experiment more with this ability. "Though if you want to know exactly what I did, basically I lowered the Ph balance of the water to one and then basically infused it into the creature's neck and blood stream. It looks nasty, but it was a pretty quick way to go really."

"This wasn't a creature, this was a human, a man. You just killed a man in cold blood!" Robin shouted, his voice incredulous as he looked between the still confused Superboy, the stoic Aqualad and the frowning and uncomfortable Kid Flash.

"Exactly, he was a human, but then he mutated his body into this thing and tried to kill us. I'll admit I could have shown more restraint, but he was out of control and trying to kill us." Percy replied looking around at Robin now, his face twisting into a slight frown as he saw the look on the boy's face.

"Look I don't know how they do things where you are from, but we don't kill our captives!" Robin snapped harshly.

"And that thing wasn't our captive, as I said he was out of control, rapid and bloodthirsty. It was a monster and I slew it." Percy retorted, beginning to get angry himself now.

"Enough." Aqualad interrupted stepping between the two. "This was a stressful situation, and our friend here put his life on the line to help us. We might disagree with his actions, but they were in both defence on himself and of us."

"Yeah, besides I think we can leave it up to them to decide…" Kid Flash interrupted as he looked up through the hole in the ceiling and at the members of the Justice League that he could see descending from the sky, and through the partially ruined roof before they fell into place, surrounding him and the others.

"Well shit…" Percy spoke up dryly, even as he sheathed his sword and pulled his coat tighter around him, buckling it closed and hiding the hilt of his sword and his bronze breastplate from sight as he eyed the group of newly arrived Heroes cautiously.

Most of them he knew of, if only by reputation. Of them all though he had only ever met one, and at present that Hero's gaze was boring into him, her waist length, dark hair flowing behind her, and her crystal blue eyes locked on Percy to the exclusion of all else, her flawless features twisting into a look of both anger and perhaps concern.

With the Hero in question being known to the world as Wonder Woman, but Percy knew her as Diana, the Princess of Themyscira and his frenemy of sorts.

Tightening his jaw, Percy resolutely met Diana's gaze, refusing to back down as sea green bored into sky blue.

It was as this stare down was occurring that Superman, a heavily built man with a red cape, a blue body suit and a golden shield on his chest with a rather red S, locked onto his clone's face, taking a sharp intake of breath as he did so. His expression darkening, even as his utterance prompted the other watching Hero beside him, Batman, to speak up.

"Is that what I think it is?" Batman questioned his gaze locked on Superboy, even as Superman resolutely avoided eye contact now, much to his clone's shock.

"He doesn't like being called an it…" Kid Flash spoke up 'helpfully', before he quietened down when he saw his own mentor, the Flash, look at him sharply. With Aquaman, an orange clad man with golden blonde hair and a beard, looking disappointedly down at his own protégé too.

"I'm Superman's clone!" Superboy announced in a yell, throwing caution to the wind as he gazed around at the reaction of the surrounding Heroes, most of whom had stunned expressions on their faces that varied throughout the League members. With even Wonder Woman looing away from Percy and instead looking between Superman and his clone in surprise.

"Start talking." Batman ordered suddenly and the sidekicks, Kid Flash, Robin and Aqualad were quick to obey, with Superboy just standing there awkwardly as the surrounding Heroes looked between the sidekicks and him, their gazes burning with suspicion, caution and curiousity.

As this was happening, Percy himself had begun edging away. Sure he wanted to be a Hero, which is why he had been here, doing some freelance investigation. But at the same time he wasn't sure he wanted the Justice League's scrutiny on him, nor was he entirely sure what their reaction would be to him, after all would they be like Robin and condemn him for killing.

It was all so very strange to him. Percy was used to slaying monsters, he was good at it and had done it many times, in fact by this point it was almost instinctive. On top of that he wasn't a stranger to killing Demigods either, as he had blown up dozens when he and his comrade, Charles Beckondorf, had planted bombs on a luxury ferry, and had killed even more during the battle of Manhattan.

Maybe it was his godly half, but fighting, and killing in the name of Olympus had always felt natural to him, as it had to the other Demigods he knew. It was in their blood, they were born for battle, born to fight the enemies of Olympus and bring honour and glory to their parent's names. Percy was no exception either, despite considering himself independent he had always done everything that was asked of him, and even when he was fucked over by the gods, mainly that bitch Hera, he had continued to do his duty, for his family, for his bloodline and for honour.

"And where do you think you're going?!" The voice of Batman suddenly interrupted the sidekick's stories, the Batman's dark gaze locked on Percy as he continued to sidle away.

"Hmm, well they seem to have everything covered, so I thought I would leave it to them. I mean you know what they say about too many cooks spoiling the broth…" Percy trailed off somewhat lamely.

He might be damn good in a fight, but not so good in an argument, or at talking his way out of trouble.

"Who are you?" Aquaman replied a frown on his face now as he locked gazes with Percy, his gaze harsh but not angry or aggressive.

"Who am I? Well who are you first? Surely you know it's polite to give your own name before demanding another's?!" Percy shot back at him, noticing as he did how Aquaman's eyes narrowed. Yeah he had heard of this Aquaman guy, the proclaimed 'King of Atlantis', well Percy had some thoughts about that.

"Smooth man…" Kid Flash muttered sarcastically from beside him.

"I am Aquaman." Aquaman replied abruptly, "Now as to my question, who are you?"

"Hmm, give me a moment to make up a name and then I'll tell you. Or are you telling me that your name is literally Aquaman, and if it is, is the first name Aqua, second name Man…" Percy retorted, probably a little pettily, but he felt like being a little arsy at the moment, plus he didn't like the man's tone. "So I have to ask does anyone ever call you semen?"

"Show some resp…" Aqualad began to say as both he and his King bristled at Percy's words, only to be interrupted by another strong, stern voice.

"His name is Perseus." Wonder Woman interrupted, her tone sharp as she looked from Batman to Percy.

"You know him?" Batman asked sharply.

"Yes, he is a Hero." Wonder Woman replied brusquely, her tone unwavering.

"No, he's a killer. He killed Desmond, after the guy took the Blockbuster formula, Percy just killed him." Robin said loudly, unexpectedly speaking up as he jumped forward in the story slightly. His words causing the recriminating gazes of the Justice League to fall on Percy.

"Thanks for the assist, snitch." Percy said dryly to Robin, before he looked around at the others. "It's a bit more complicated than that, Desmond turned himself into a mindless monster and tried to kill us, I put him down."

"Things happen in the heat of battle." The dark-skinned green Lantern spoke up at that, with the two bird themed Heroes, Hawkman and Hawkwoman nodding along in agreement. "When in a fight things move swiftly, sometimes there is no other choice."

"What you can't possibly justify this guy killing someone!" Captain Marvel interrupted, his voice full of outrage.

"There is a fine line, but I agree with Green Lantern, sometimes it is necessary. But where possible it should be avoided, those with power must show responsibility." Martian Manhunter pitched in, his tone low and slow, but his words containing a certain weight.

"But if we do give in to that impulse then it will make us no better than the criminals we fight." Green Arrow argued.

"There is a big difference between killing an innocent or a captive, and between killing a man turned monster in mortal combat." Wonder Woman cut in harshly, her gaze moving over the rest of the League as all the members present had a different perspective on the ethical issue of how much force is too much, and is killing ever right or acceptable.

"The Justice League operates by a code, one that condemns killing." Batman cut in, even as the various members began to argue, oblivious of the watching sidekicks, or of their current surroundings. "But in the heat of battle things can happen. Besides this Perseus, is not a member of the League, and so is not accountable to our code. However he is a powered individual, one who seems to want to be a Hero."

"It's just Percy." Percy said after that.

Even as Wonder Woman cut in with her own comment. "Perseus has my full support."

"I do?" Percy replied in surprise.

"He does?" Aquaman asked in confusion, even as many of the other Heroes and sidekicks also looked confused by her words too.

"We'll speak about this later back at Watch Tower." Batman said, looking over to Wonder Woman now who gave a curt nod in response. "Everyone is entitled to their secrets, but if it will potentially threaten the Justice League or the innocent then I'll want to know."

"I will tell the inner circle what I believe necessary." Wonder Woman replied brusquely, before she looked around at the others. "But other than that, like Batman said, Perseus, like everyone else is entitled to his secrets."

Percy frowned as he heard this, but didn't object, after all Wonder Woman only knew so much about him, and even then that was because the Amazonian's guarded the gate of Tartarus on this world, a gate that Percy himself was very familiar with.

"Very well, now continue." Batman said with finality, before he looked back to Robin, who in turn pushed back his own burning curiousity and continued the story. During which Percy continued to get many glances from the assembled Leaguers, especially when Robin 'helpfully' described some of his abilities, or the ones he had seen, and Aqualad pitched in on some of his Hydrokinetic capabilities.

All of which got intensely curious looks from Aquaman, as well as a narrowed eyed judging look from Batman.

"…and then Superboy landed a final hit on the dying Blockbuster, which knocked him through a pillar, and well…" Robin trailed off as he gestured over at the lifeless body of Blockbuster that was still buried under the rubble.

It was a pretty brief retelling, but Percy had to admit Robin had locked onto most of the key points, on top of which he was very curious about the confrontation with the horned genomorph and the realisation that this being had been controlling other genomorphs and had been helping Superboy. It almost made him feel guilt for kill so many of them, then again the fact they had been trying to kill him at the time assuaged some of that guilt though.

"We'll uh… we'll figure something out for you. The League will… I mean. For now… I'd better make sure that the rest of Cadmus is properly secured and investigated and Guardian is safe." Superman said awkwardly to Superboy as the rest of the Leaguers broke up, after which he turned and flew away, leaving a very frustrated and disappointed Superboy behind as he did so.

Not that Percy really paid much attention as his gaze was instead on Wonder Woman as she strode up to him.

"So this is what you've been up to." Wonder Woman said bluntly as she came to a stop in front of Percy.

"Well yeah, did you really think I was going to stay on that island?" Percy replied abruptly.

"You could have told us you were leaving, as opposed to just disappearing one day." Wonder Woman replied, her tone still tinged with anger.

"You're telling me that you wouldn't have tried to stop me?" Percy retorted, only for Wonder Woman to pause, as she found she couldn't answer that. "I thought so."

Wonder Woman frowned at that, even as she looked over to where Batman, Aquaman, the Flash and Black Canary were confronting the other three sidekicks and Superboy. The conversation looking tense as Batman apparently told them something they didn't like, which in turn made them group together as they looked challengingly at their mentors.

"So what happens now?" Percy asked into the silence that followed, bringing Diane's attention back to him.

"I… I'm not sure." Diane replied, shifting about as she met Percy's eyes, before she then looked over his shoulder to where the sidekicks now seemed to be celebrating.

AN: So that's the chapter what do you all think? I hope you enjoyed it and review!?

Other than that I can also confirm that I have decided on a final pairing for Percy, or one that I want if thing plan out how I want them to, a pretty much unused one, and one that a feel will be pretty fun to explore. Not that I'll be letting it slip, because I am a bastard like that and enjoy keeping people waiting. That being said since I don't believe in love at first sight at all, Percy, like other normal people, will be dating around a bit before he meets the one.

That being said that doesn't mean that this will be a harem story. I'm afraid I don't like those types of stories as a rule, in fact thus far I've only read three harem stories that I genuinely liked, I've got my eye on a couple of others as I wait before making my decision. The reason being that those types of stories have poorly constructed characters, cringey dialogue, shallow, hollow MCs, with some of them being so bad that I just stopped reading and gave up.

In fact I myself was guilty of writing one such story on my other account, one of my very first stories, a Naruto/ Highschool DxD called Ten Tailed Wolf, which I gave up on because it was so bad. So yeah I'm sorry but the occasional multiple pairing yes, harems large or small, no. I don't feel confident enough in my abilities to write one.

Next thing I want to mention is Percy's abilities. I went over all of them in this chapter, for those who are interested I will put a list down:

Hydrokinesis:

- Manipulating Water, solidifying, molding and drawing it from multiple sources.

- Manipulating Water on a molecular level, making water boil, freeze and changing its Ph.

- Blood control, manipulating the water inside of bodies. This is unperfected, harder to control and has limits.

- Toxikinesis and Cryokinesis

Geokinesis:

- Basic geokinetic abilities

- Vibration manipulation, absorption, enhancement and creation of seismic waves (Quake from Agents of Shield if you want an example)

- Potential for metal bending (see Avatar the Last Airbender for example)

Creation of storms (limited skill and practice in using this, thus far):

-Electrokinesis (limited)

-Aerokinesis (limited)

Heat Resistance

Resistance to pressure

Other than that he has the standard abilities of a stronger than average Demigod (Riordan verse)

As you can see I have expanded on all of his canon abilities far more than they were developed in the books. On top of which I have expanded on Percy's character more, making him someone who learns and grows from his experiences.

Wow longer AN than I thought, still you got a big junk of story too, so meh. Other than that I hope you all continue to read and enjoy, I have plenty more planned!

Thanks a lot for reading and please leave a review. Try my other stories too if you have some time.

Catch you later.

PS. Can anyone recommend me any good stories to read?
