Invisible Demons

Back at Titan's Tower Raven explains to Robin and the others about her experience with Dark. "He was definitely an interesting one…" Raven says thinking about Dark's personality and beliefs. "From what he said he doesn't like the way humans live." She continues. "He didn't tell me anything about his people or where he came from just that he wants this world to change for some reason." Robin looks at a computer screen with his arms crossed listening. "Well he's definitely not human." He says looking at the images from security cameras that caught a glimpse of Dark. "His weapons seem to be able to change for the situation lethal or non-lethal as we saw with those shoulder mounted lasers, he used one on one of two burglars when a home invasion went bad." Robin says. "They are very similar to the hunters I thought this Dark person was." Starfire comments looking at an image of Dark's shoulders. "How similar?" Robin asks, "Almost identical." She responds bringing up a mental image. "These hunters would they share their technology with any other species?" Robin asks. "I do not know Robin they almost never contact other species they only hunt them." Starfire says shivering at the thought of it. "I found something on these hunters when looking through events that happened with them, quite a few, even Batman fought one." Robin says pulling up another file on the computer. "Well did you ask him if this guy could be one?" Cyborg asks. "He said it's unlikely after he saw the images of Dark." Robin says his hands crossed again leaning back into the chair. "Really I mean this guy does have a few of their weapons along with their attributes." Cyborg says looking at the screen. "Impossible this guy speaks perfect English, his skin is similar to a human, he's too short to be one, and the attributes…he's way stronger than them." Robin responds. "…Well maybe we should call in some back up." Cyborg says smiling. "Maybe we should." Robin agrees. "I'll call Titans East you try to get Kid Flash and Jinx if we need anymore make sure they're all ready." Cyborg says running out of the room. "Friends do you think we can really stop this man?" Starfire says nervously. "I'm sure we will Starfire." Robin says putting his hand on her shoulder. Starfire smiles and walks out of the room. "You really think we can stop him?" Raven says watching to make sure Starfire left. "Why would you ask that?" Robin asks. "You've seen what this guy can do he knocked you guys out precisely without any damage to you physically or mentally he's precise with any attack he does." Raven says playing back security camera footage. "See how he was capable of killing these people to make them suffer? He knows what he's doing and probably knows a lot more, Aside from that he said that glider we destroyed was just a prototype imagine what his bigger technology can do." Raven says thinking. "That is true but we've taken on stronger things than him." Robin says walking out. "I think he may be the most difficult challenge we've ever dealt with…" Raven mutters to herself walking out of the main room.

Meanwhile deep into the forests of Jump City the entrance to a ship uncloaks as Dark walks towards it as soon as he is inside it cloaks once again. Once he is inside he walks up to a woman in red armor. "What where you doing out there Dark? You where holding back plus they destroyed the prototype glider." She says her arms crossed. "You know I will not hurt them in any way Scarlet." He says. "Dark I don't want you getting hurt or exposing yourself that is not part of your mission." Scarlet says. "I made this mission you know that you are all only here because they don't want me out here alone." He says folding his arms behind his back. "Look we'll go over this later but command wants you to use this place as a training ground for you student." She says handing him a small disk. "Damn it if it was sooner I would have but with the Titans on my tail this is going to be difficult…" He says taking the disk. "You did it in steel city didn't you?" Scarlet asks, "Yes I did but that was different that was from over a mile away plus the Titans East weren't alerted till after the shot was taken." Dark responds tucking the disk away into his armor. "They still have no idea who did that here though they know I exist and are trying very hard to capture me." "Should I have the twins ready an attack gunship just in case?" Scarlet asks smiling. Dark looks at her and shakes his head walking past her. "That kid takes everything too seriously…" Scarlet says watching him walk away. Dark walks through a corridor into a darker part of the ship he presses a button on his gauntlet opening a door he walks into his quarters. "I hate these ships…" He says sitting down he pushes another button a wall folds out revealing weapons and tools. Dark grabs a large rifle from one of the racks he sets it down onto a table and begins cleaning it. "Looks like we're going to have another lesson…" he says to himself taking the rifle apart. After putting the rifle back together he hears a beep from his door. "I told you people to leave me alone…" Dark says as the door opens. "Oh sorry thought you were someone else…" He says. A woman in grey armor stands in the doorway with a book. "Sorry to bother you teacher but I just wanted to know if this calculation for this scenario was correct." She says showing Dark the book. "I told you call me Dark I'm not like the others anyways let me take a look come in." Dark walks over to a desk the young woman sits down across from him. He nods "This would be a perfect shot but it depends on what species." Dark says pointing to the picture, "This is a standard hostage situation someone has a weapon pointed to the head of the hostage while they're behind the hostage now." Dark waves his hand over a small ball it brings up a hologram of a human head and its anatomy. "Now since we're on this world we'll use a human as an example you see the shot would go right here between the eyes the only problem is this may cause the target to pull the trigger which would kill the hostage I would recommend aiming for the medulla oblongata this controls blood pressure and breathing in a human it is located here in between the cerebrum and spinal cord." Dark explains to her showing the simulation of the bullet hitting the target. "But in this scenario would require a reflect shot to hit the medulla oblongata which would be very difficult wouldn't it?" She asks him pointing to the angle that the shooter would be facing. "Exactly there is actually numerous ways to this entire scenario." Dark says pointing at different objects at the hologram. "Any of these can be used to reflect the shot the only problem is you may hit the hostage or you may miss completely along with that the projectile would lose speed and kinetic energy reflecting off a surface." Dark says the hologram showing the bullet's flight path reflecting off different objects. "Along with that it would take a bit of time for the projectile to hit so the target would hear it then probably pull the trigger so a suppressor would be required." Dark continues. "So this is supposed to make me think differently about shooting is that why you made this scenario Dark?" The girl asks. "Exactly and you gave the answer I wanted you to think of which is why I chose you Nezumiiro as my student." Dark says. "Remember call me Nezu…" Nezu says smiling. "Alright then Nezu well is this all or did you come up with shots like I told you to?" He asks clearing the hologram.

The next day at Titan's Tower Titans East and Kid Flash along with Jinx have arrived to help the other Titans in capturing Dark. "So who is this guy that none of you could take down?" Bumblebee says pointing to the monitor that has an image of Dark. "He calls himself Dark he's a ruthless vigilante killing anyone who harms anyone else." Robin says pulling up files of Dark's crimes. "Dark has murdered many criminals in and out of jail the only thing is he only kills the ones that kill themselves or harm another physically or mentally." Speedy watches the playback from Cyborg's recording of the Titan's failed ambush "He's fast, very fast, but how did he know you where going to attack?" Robin rubs his forehead "Raven thinks he…heard us planning the attack…" Speedy looks surprised at the distance Dark was. "He was a good forty meters away from you how could he have heard it?" Robin points to Dark's mask "We believe his mask gives him advanced vision and hearing as well as the ability to target with most of his weapons." Bumblebee points to the red laser coming out of Dark's helmet "What is that?" She says tracing the path with her finger. "It's some kind of laser targeting device the only thing is it's visible to the human eye." Cyborg says "We have some scraps of his technology that he left behind from his killings it is amazing." Cyborg says holding out a small spear like object. "Feel this it weighs almost nothing but went through two people before embedding itself into a wall." Speedy takes the spear from Cyborg's hand tracing the blades with his finger. "It's sharp and feels like its weightless what did it do?" He says handing it to Bumblebee "Killed two criminals straight through their heads." Robin says showing them crime scene photos." Bumblebee looks away and Speedy looks sick. "Wait a minute…" Bumblebee pulls a small object in a bag that looks like a bullet. "This was found in Steel City it killed a CEO of a company that was going on trial for pedophilia." Robin opens the bag and feels the bullet "…Feels weightless what is it made out of?" He says handing the bullet to Cyborg. "It didn't show up on the periodic table." Speedy says "You don't think…?" Robin compares the spear and the bullet both look like they're made of the same material. "I think Dark took that shot where was it taken from do you know?" Robin says putting both objects down on a table. "From miles away some people that where out biking on a mountain that can be seen from the courthouse said they heard a loud boom then a few seconds later the CEO was hit in the head by that bullet." Bumblebee says pointing to it. "He was hit in the head!?" Cyborg says looking at the bullet. "That shot would break the record for the longest shot ever made by a sniper in Afghanistan, also look at it it's barely damaged the bullet should have pretty much exploded and fragmented it went through the CEO and hit the cement but it is barely damaged." Speedy says feeling the bullet. "It's also barely deformed from being very hot after leaving the barrel of the weapon. What caliber would this be in human weapons?" Robin asks showing Cyborg the bullet. "A 50 is what the police said it probably was." Speedy says staring at the image of Dark. "I think this guy took the shot or knows who did." Bumblebee says also staring at the image.

Dark stands with Nezu both looking at a map of Jump city "Okay then our targets are here they will be hijacking and shooting both guards at exactly 3:12 PM we can either take them out from this abandoned office building which is over 2,243 meters away or we can get in closer here from this grass area and hide within the bushes with our ghillie suits." Dark says pointing to the various points they can take the shots from. "Well what is in the path that could be dangerous for us to take the shot from the office building?" Nezu asks following the flight path of the bullet to the target. "Innocent bystanders I suggest we go in close for this about 800 meters out with suppressors on the bolt actions." Dark says showing Nezu the grassy area with bushes on the map. "We'd both have to take at least two shots since there are four of them." Nezu says thinking. "The other problem with this is we'd have to distinguish the targets very quickly along with that we'll have to take out these cameras that could see us with suppressed small rounds." Dark says pointing across the street from the targets. Nezu looks at the map "Maybe we should take the shot from the office building it will be harder but getting in that close could be very dangerous especially with these Titans looking for you." Dark looks at Nezu and nods "Very true plus if they catch word of this they'll see us we'll take the shots with the high caliber rifles from the office building the only problem is if anyone's in the vicinity they'll hear the shots but we'll be out of there after all four targets are down. We'll leave soon so get your equipment ready." Dark says the hologram map vanishing. "Ghillie suits right Dark?" Nezu asks, "Yes since both areas where we will take the shot from provide a lot of vegetation cover." Dark explains "Now go get ready." He says walking out towards his quarters. Once inside Dark begins taking off his armor "I hope the Titans don't interfere if they go after her I'll have to shoot…" Dark says to himself putting the suit on making sure nothing makes a sound when he moves. A little while later Dark walks out with three rifles in cases covered with leaves and grass he walks to the ships launch bay towards a large gunship two women are there one in the cockpit the other behind at the engines "Hey Dark, you two using that human stuff again? Why not just use the cloaking devices it's a lot easier isn't it?" The one in the ships cockpit says pointing to Dark's suit. "The ghillie suit is an amazing feat of stealth made by humans I respect them for making this." Dark responds dropping the rifles through the large side door of the gunship. "Well if you guys get spotted call it in and paint a target and we'll handle it." The woman behind the ship says walking into the other side door towards the cockpit. Nezu walks towards the gunship carrying her rifles. "Well if it isn't the mute." One of the twins in yellow armor says. Dark looks over to her then at her weapons "You remembered to ghillie them correct?" He says pointing to the cases. She nods Dark helps her up into the gunship they both sit in the back.

Dark grabs a small cube from his suit and activates it a hologram map comes up with different colored areas that surround Jump City "These are the meet up points if we must split up and get out as quickly as possible remember if the Titans do spot us I will hold them off so you can get away to pick up point Alpha okay?" He says tracing the area. "I know but that won't happen hopefully…" Nezu says checking a large rifle. Dark puts the cube back into his suit "Remember though stun rounds only on the Titans or anyone else the targets go down with lethal rounds." He says showing Nezu the two different rounds. "I understand Dark." Nezu says loading her weapons. Dark does the same loading each rifle. "You guys ready to go?" One of the women in yellow armor says turning her head towards them. "Take off now." Dark says as the gunship doors close. "Alright Yellow 1 and 2 ready for take off." The woman says as the ship begins to rise slowly towards the launch bay door. Dark looks out towards the sky as the gunship exits the large cloaked ship. "Engaging cloaking device now." One of the pilots says. The ship speeds up quietly towards Jump City. "We'll be hitting the LZ in a few minutes get ready." Yellow 2 says to Dark. Dark responds by loading a round into a rifle "You ready?" He asks Nezu who does the same. The gunship doors open Dark looks out towards the city lights. "Alright hit it!" One of the pilots says a rope extending down to the ground as the gunship hovers. Dark quickly grabs the rope sliding down it with Nezu following. As soon as they both land the rope pulls back up into the gunship the doors closing. "Alright Dark good luck we'll help you guys out with a bird's eye view of everything." One of the twins says over the radio in Dark's earpiece. "Just watch out for the Titans." Dark responds crouching down studying his surroundings he makes a hand gesture for Nezu to follow. They both walk slowly towards a run down part of Jump City grass overgrowing in the area "They abandoned this part of the city due to it being close to an earthquake fault line a few years back." Dark says as they slowly walk towards the rest of the city. "There that's where we'll be taking the shot from." Dark says pointing towards the tall building in view. "About 300 meters away." Nezu says, "Exactly this is as close as we could get in by air due to the large population that could see the ship as we exited it." Dark says. "Come on lets go." Dark says as they run towards past old houses. "Yellow One and Two do you see anything?" Dark says into his microphone. "Affirmative looks like we got some guys chasing some kid you guys better take these two guys out they're armed." Dark stops hearing footsteps and shouting. "Nezu you grab the child I'll take care of these two." Dark says readying his rifle. "They should be coming in view now." Yellow Two says. Dark and Nezu watch as a young boy about the age of 11 runs bruised from two large men one with a baseball bat the other with a knife. "Nezu make sure the young one is okay." Dark says standing up. The young boy stops as he sees Dark. "Get behind me." Dark says gesturing to the boy who does so. The two men both still holding their weapons stop "Give us the kid and you don't get hurt freak." One says as the other laughing at Dark's Ghillie suit "What do you want with this child?" Dark says watching the two. "None of your business!" One shouts. Dark turns to the boy "Why are they after you?" "T-They hurt my mom." The boy says staring at Dark. Dark turns back towards the two. "Nezu cover the boy's eyes." Dark says as one of the men runs towards him as soon as he is close enough Dark hits him with the butt of his rifle in the stomach knocking him over.

"We killed the stupid bitch!" The other man shouts. Dark points the rifle at the man on the ground "Then you are both going to die." Dark says pulling the trigger of the silenced weapon. "W-What!? You can't do that!" The man with the bat yells backing away seeing his dead friend. "I can do anything." Dark says aiming at the man who tries to run he fires again hitting him in the back of the head. "Nezu lets go we'll take the child as close to the city as we can." Dark says looking down at the boy. "Where's your mother?" Nezu asks gently. "She's over here." The boy says pointing towards a street. "We where out shopping when these men came after us." The boy says crying. "Come on maybe we can save her." Dark says running towards the woman on the ground bleeding. "Heart rate is low she's still breathing Nezu give me the injector." Dark says holding out his hand. Nezu hands him a small vile with glowing blue liquid Dark injects it into the woman's arm. "She'll be fine kid don't tell anyone about us okay?" Dark says the boy nods. "Let's go." Dark says to Nezu they both vanishing into the thick bushes. "Man this is going to be a highlight reel!" Yellow Two yells. "You two are recording again?" Dark says annoyed. "Duh we have this camera on this ship for a reason!" Yellow One says. "Remember though what I just did can get me in some big trouble." Dark says as they advance towards the building. "Don't worry Dark your secret's safe with us." Yellow Two says. "Alright Nezu, things are starting to get busy as we get closer to the building it's about to be torn down and is close to a small neighborhood." Dark says as they watch cars go by. "We have to be quick and quiet getting there." They walk slowly towards a small neighborhood. "Damn it, people could see us." Dark says seeing people out on their porches. "Dark I have an idea." Nezu says Dark looks back at her she points to the roofs of the people's homes. "Good idea." Dark says climbing onto a house. "Remember stay on the side so they can't see you." He says helping Nezu up. They both run silently jumping from rooftop to rooftop of the small homes a dog barks at them but doesn't see them for long. Once over the final building they look at the office building. "We're almost there." Dark says judging the distance. They crouch walk silently towards the building "Get down now!" Dark says both lying down quickly in the grass now unseen. "Damn it Yellows I told you two to watch out for the Titans!" Dark whispers angry into the microphone. "They just appeared out of nowhere you guys better lay low." Yellow One says. Dark looks up slowly at Starfire, Raven, and Bumblebee on patrol in the area. "Damn it they called in more." Dark whispers to Nezu. "They will see us if we move too fast move nice and slow while they're over us follow the wind." Dark says as they slowly crawl under the bushes the Titans still unaware of them.

Starfire, Bumblebee, and Raven where sent out to patrol the area after someone had called in that they heard screams nearby. A woman and her child had been attacked by two muggers who almost killed her but was somehow saved. "The kid said the two guys where taken down but he didn't say by what." Bumblebee says looking down towards the small neighborhoods and run down neighborhoods. "Maybe the child was wrong?" Starfire says. "No way his mother was beaten and stabbed she's making a full recovery very quickly even as the police found her." Raven says scanning the area below them. "Well girls we better keep searching maybe they ran into an abandoned building." Bumblebee says pointing towards a large office building. "Wait what's that?" Raven says pointing below them. "What?" Bumblebee says looking down. "I thought I saw something move." Raven says staring down looking for any movement. "Must've been the wind girl or your mind's playing tricks on you." Bumblebee says. "Friends I believe I found the two men…" Starfire says pointing far down towards two bodies both bleeding. "We'd better call this in…" Raven says grabbing her communicator. Down below them Dark and Nezu listen to their conversation. Dark whispers silently to Nezu "Damn it this place is going to be crawling with Titans we have to get there now!" Dark looks up at them watching the Titans. "On my mark we make a run for it okay?" Nezu nods watching the Titans. "Hold…Hold…Go!" Dark says both running very quickly towards the hotel they stop behind a parked truck in a quiet street across from the office building. "Okay I don't think they saw us." Dark says looking up at the three Titans. "Let's hop the fence and get in there now." Dark helps Nezu over the fence then jumps over himself. They enter the building and get to the top floor. The Three Titans fly towards the bodies on the ground. Raven looks at the wounds on both men. "They where shot." She says turning to the other Titans. "By what though? I mean shouldn't someone have heard the gunshots?" Bumblebee says looking down at the two. "Look we'll wait for the others to come before we make any assumptions." Raven says watching as an ambulance and police cruiser pull up.

Dark and Nezu watch the other Titans arrive at the scene from the office building. "Let's see Robin, Cyborg, Raven, Beast boy, Starfire, Bumblebee, Speedy, Aqualad, Mos, Menos, Kid Flash, and Jinx. They're definitely trying to catch me." Dark says looking at all of the Titans through his rifle scope. Nezu laying next to Dark in prone watches the Titans as well. "Let's hope they don't find out where we are." She says turning to Dark. "They won't unless they come up here." Dark says still looking through his scope. They watch as the Titans leave after talking with some officers. "Good…" Dark says watching them all go. As he watches Raven looks up at the building from the T-car thinking to herself. "Why do I have a feeling someone's up there?" She thinks not seeing Dark and Nezu in the darkness. Dark looks down at her then quickly hides in the shadows. "Damn it I think she saw us." He says looking back down at the T-car. "We'll wait it out and take the shots we have quite a while…" Nezu says looking at the moon. Dark sets up the large rifles checking both the sights. "Well we're ready." He presses his earpiece into his ear "Yellow One and Two we're roosted in the building tell us if anything comes our way." "Roger that Dark we'll update you if we see anything." Yellow Two says. Dark and Nezu watch from the building silently waiting for 3:15 PM. Back at Titan's Tower Robin stays up late again pondering at what is going on in the city. "First someone takes out that CEO in steel city then Dark comes to Jump City…" Robin says yawning reading newspaper clippings and police reports. 'INVISIBLE DEMON ON THE LOOSE!' reads one headline for a newspaper article on Dark. 'ARMORED AVENGER GOING TOO FAR?' reads another. "He's scared almost every criminal in this city not to do anything because of the consequences he puts down on them." Robin says to himself. "But how does he know where they are? Does he have some kind of inside connection?" Robin passes out at his desk over the various pieces of paper.

Well that's it for this chapter just a bit of a hint, notice anything about Dark's species?
