Okay starting a story here that I just did to pass the time. I wasn't sure about submitting this, but due to a friend of mine's constat nagging to submit this I relented and posted. He introduced me to Devilman and I got to say that I liked it.

This became a crossover with Young Justice because I have been watching a marathon of it at home with my little brother and figured what the heck. So without further adu here it is.

Chapter 1: Devilman

It was a late night in Gotham. Some people were still out on the streets walking home from work, but they were not the only ones out. On the roof tops Batman and his sidekick Robin were out on patrol, searching for any criminal activity. They had already stopped a several robbers from breaking into a jewelry store and the police had come to collect them and take them to prison, but it was still early in the night there would no doubt be other criminals up and about.

The two just landed on another roof and looked down at the streets being Robin looked over the edge and looked down into a alley way and his eyes narrowed at what he saw.

"Hey Bats," Robin said queity, but loudly enough to get his attention. Batman looked at his partner and quietly moved over next to his partner and looked down into the alley way and saw what he was pointing at in the alley below. Batman saw two men with ski masks on their heads and guns in hand, no doubt intending to rob someone or break into a store like a couple of criminals they encountered earlier were.

"Alright we just have to wait a little while longer, when the owner of the shop leaves and then we can sneak in and rob the place," one of the thugs said.

"But what about the Bat," his partner replied.

One of them groaned in pain as he dropped his gun and held his stomach. He leaned against the wall to keep himself up. The man's partner placed a hand on his shoulder and asked. "George, are you okay?"

George didn't respond as he kept leaning against, groaning in pain. After a few moments he leaned off of the wall and placed his hands back on his side.

"Yeah in fact I never felt better Fred," George said, with a large grin on his face that reminded the two heroes of the Joker for a moment. The smile showed all of his teeth, but Batman noticed that there was something wrong with his eyes for just a moment.

George then launched himself onto the man his partner his mouth biting into his neck, surprising the heroes as he ripped off a large amount of his neck as he chewed onto the flesh and meet as if he were eating a steak. When George pulled back and dropped the dead corpse of his former partner he smiled sadistically and the two heroes saw that his teeth no longer seemed that of a human's, but were now longer, jagged, and looked to be as sharp as razors, like an animals were.

His eyes were no longer the same and were now amber with slits in them. As they looked at the man, they saw that his body was growing as scales appeared on his arms. When he was finished growing he now looked like a mix between a human and a snake, with a long pink forked tongue and sharp claws. The two heroes didn't waste any time and jumped down into the alleyway and launched themselves at the Meta-human, kicking him back into the street.

George was slightly surprised by the sudden attack, but only moved a step back as he looked at the Dark Knight and the Boy Wonder.

"Well this is a bit of a surprise, but I ain't complaining," the 'Meta' said to himself, looking at the two as if they were a prime rib steak, licking his lips with his forked tongue. . "Nothing like a good old bat and a Robin for the side after a appetizer like that."

"You really think that you can take us both on alone, we took bigger guys then you on before," Robin said, smirking.

"You think that, but in reality I'm not. In fact the fun's just begun," he replied with a sadistic smirk.

They then heard screaming coming from the streets and the two heroes turned toward them and they were surprised by what they saw. Everywhere on the street people of all ages were changing, some of their bodies grew in size while others remained the same size, but grew other appendages such as horns or wings.

Those that didn't change screamed in terror of that people that did, who were now looking at them as if they were lunch.

And they were.

"Robin, get everyone out of here," Batman ordered, as he pulled out several Batarangs and threw them at the 'Meta's', hoping to get their attention and keep them from hurting anyone else.

Robin only nodded as he quickly got all of the civilians out, while making sure that none of the…Meta-humans got to any of them. When he managed to get everyone he was about to move to help Batman, but a teenager with short shaggy black hair walking down the street across from him wearing black jeans, a black leather jacket, and a black pair of sneakers. The teenager was walking toward Batman and the Meta's as if nothing was happening.

"Hey get out of here!" Robin yelled, at the teen, only to be ignored as he continued walking toward the demons, not slowing down at all. As the teen walked toward them he noticed that the person's hands were tightly balled into fists as the teen moved his head from one side to the next, cracking his neck.

As he stared at the teen it took him a moment to realize that something was off about him. It was then that he noticed that the teen's body was growing, his clothes tearing as he did.

His hair merged together and formed a pair of dark black bat wings appeared on the sides of his head as his teeth seemed to have sharpened. As his body grew, his skin turned into a light violet as his muscles grew larger, his clothing being destroyed in the process. As he grew a dark substance was coming out his arms that completely covered his forearms that took the form of claws. It didn't just cover his arms though. It also covered the lower part of his body from his waist down. A long black tail with appeared with the end of it being an arrow-like tip.

"A De-Devilman!" One of them stuttered in fear at the being in front of it, making Batman to raise a brow at the term and Robin to curiously look at Devilman. The transformation was unlike any that he had seen and looking at the being now he noticed that all of Devilman's teeth were sharpened like an animal's and that he had pupiless golden eyes with black markings around them.

Devilman jumped toward the demons and punched one in the face sending it flying back as he kicked another and then punched another in the face. He then lunged forward and swung one of his claws at the demon's chest, ripping off a large amount of skin on its chest and causing blood to pour out of the wound.

The demon that had stuttered earlier turned around and ran away. Devilman noticed the demon trying to run away and punched and kicked any demons that had gotten in his way. Devilman jumped toward the demon and landed in front of it, before it could react Devilman had shoved his clawed hand into the demons chest, causing it to gasp and blood to pour out its mouth.

Devilman moved his hand and stepped to the side as a demon that looked like a gargoyle try to slash at him with its claws only for Devilman to grab its head. The demon struggled in Devilman's hand under the pressure and clawed at his arm and anywhere else he could get, trying to make him let go.

The demons clawed scratched Devilman's upper arm and a small part of his chest. Devilman hissed in pain and then squeezed the demon's head, crushing it like a grape in his hand. Blood poured out of his hand that held the crushed remains of the demon's head, as its body fell lifelessly onto the ground.

Unlike Batman and Robin who thought they were dealing Meta-humans knew what they were really were. They were demons and Devilman was their executioner.

Batman and Robin were surprised by the sheer brutality that Devilman fought with. He didn't fight like a trained fighter, but more like an animal.

"That's enough!" Batman yelled at Devilman, who ignored him as he ripped off one demon's arm and then throw it at another, the blow knocking the demon onto the ground because of the force.

A demon that looked like a humanoid gazelle on its hind legs quickly charged at Devilman headfirst. Devilman turned toward the demon and quickly grabbed it by the horns, a few inches away from his body. He then ripped them off as he kicked it away, sending it flying into another demon.

Devilman threw the horns into a demon that looked like an overgrown insect, the horns piercing its heart and it neck.

Devilman appeared in front of George and punched the demon sending him flying as he quickly lunged after the demon. George flipped himself over and tried to punch Devilman, but he had caught his fist and when George tried to punch him with his other one he caught and then flipped himself and kicked him with his feet sending George flying back into a wall.

Devilman charged forward and grabbed George's shoulder and punched his head with all of his strength, crushing George's head.

"My god," Robin muttered to himself, starring at the massacre, pale as a sheet.

Batman couldn't blame Robin for saying that. In all his years as a hero he had never seen a massacre like this or a person fight with such monstrous brutality. Not even the super villains that he had fought on a daily basis was this brutal.

Devilman let go of the dead demon's body and began walking away, but stopped when he felt that someone was glaring at him and turned around and saw that it was Batman and Robin. The two were glaring at, no doubt for his actions against the demons, but he didn't care. It was either them or innocent lives and he would standby his actions, no matter what.

Batman glared at Devilman and Robin recognized the glare as the infamous 'Bat glare' that he used against criminals sometimes other heroes in arguments. To his surprise Devilman didn't so much as flinch from the sight of it. Even Superman flinched when Batman used it on him.

Devilman for his part merely raised a brow at Batman and was wondering if the glare that Batman was sending his way was supposed to intimidate him. If it was then he needed to do a lot better than that. He had faced many demons ever since he had first became Devilman, and most of them were far more intimating then the Dark Knight could ever be.

"What?" Devilman asked as the two stared at one another.

Batman didn't show it, but he was inwardly surprised that Devilman didn't so much as flinch from the glare that he was sending at him. Even Superman and some of the other heroes cringed from the infamous 'Bat glare' and they have been working together for years.

To Robin this Meta was either believed that he could take them both on, or he was just as crazy as the Joker was.

"You're under arrest," Batman said, with a barely noticeable edge of anger hidden underneath that nonchalant tone. "And we will use force if we have to."

"Look I really don't wanna fight you Batman, because you're a hero, but if I have to stay a free man then I will," he replied, balling his claws into fists.

Batman pulled out several smoke pellets and threw them at Devilman who closed his eyes and stopped breathing to prevent any of the smoke from getting into his lungs. It was then that he felt punch his jaw, and he quickly swung his arm in retaliation, clearing the smoke in the process as he saw Batman jump away just in time, to avoid getting hit.

Batman pulled out several Batarangs and threw them at Devilman who quickly brought his arms across his body, the Batarangs exploding harmlessly off of his armored arms.

Robin threw several Bridarangs at Devilman, but just like before with Batman they exploded harmlessly against his arms, and before Robin could move Devilman quickly grabbed the Boy Wonder's body, with just as much power as an anaconda would have when it was wrapped around its prey.

"You're gonna have to do better than that," Devilman remarked as he threw Robin, sending him flying into the wall.

Batman threw a couple explosive Batarangs at Devilman only for him to block them with his arms and then fly through the smoke at Batman. Devilman threw a punch at the Dark Knight, who barely managed to avoid the punch, and then another, but this time it was faster. Before he could react Devilman threw another punch, making sure to hold back his strength so that so that he wouldn't kill him.

The punch hit Batman's chest sending him flying into a car that skidded back from the blow. Batman groaned as he got up, knowing that Devilman was holding back. He wasn't fighting with the same monstrous ferocity that he had earlier and he could tell that he was holding back, even though he was still fighting with a brutality and ferociousness that most people would never have in a fight.

In fact he seemed to be fight mostly defensively and countering when he could.

When he got up and steadied himself he didn't move to attack and instead looked at Devilman and saw that he didn't charge forward either, like he did with the demons earlier, and instead stood where he was, ready to act on a moment's notice if he or Robin tried anything.

"Why are you holding back?" Batman questioned, starring at Devilman, who only shrugged.

"I could ask you the same thing, considering how you deal with criminals and super villains on the daily basis," Devilman replied. "Why are you asking?"

"The way that you attacked those people before showed that you have no problems with killing people, but you aren't fighting to kill me or Robin at all. You're careful, you're not fighting with the same monstrous ferocity that you had before, you're fighting defensively, why?"

"They weren't people…not anymore," he answered, causing Batman to narrow his eyes as he looked him over for any sense that he was lying, from the slightest twitch to his eyes or drumming his fingers to distract himself

He found none.

Instead he stared back at him unblinking, his body steady as he looked back at him.

"What do you mean?" Batman questioned, surprising Robin.

Robin on his part was surprised that her mentor and father figure wasn't trying to capture him and instead was having a conversation with him.

"They weren't the person that they once were anymore they died the moment that their bodies were taken over by them," Devilman answered

"Taken over by what?"

"Because of the way that they looked and the way that they acted, ask anyone of the deceased families and they will tell you that they weren't a Meta-human at all. They were just ordinary people until today," Devilman answered, not going into specifics. "Believe what you want, it doesn't change anything, I still killed them and saved lives today, but that doesn't changed what I did in your eyes. In your eyes I still killed."

After he said that a large set of bat-like wings appeared on his back and flew away. He didn't want to fight a hero, especially a hero that was a member of the Justice League, especially one of its founding members like Batman was. Batman would tell the League and if they ever saw him they would try to capture him for questioning or because of his brutality to deal with the demons lock him up.

Batman quickly took out a tracker and threw it at the flying Devilman, as Batman watched the flying demon he pulled a small pad out of his belt and watched it for a moment as he saw a small green dot moving away.

As Devilman flew through the air he made sure that he was high enough so that no one could see him.

When he landed on the ground Devilman's body soon began to shrink, the wings on his head turning into black hair as the dark substance that covered his arms, legs, and back was absorbed back into his body, his hair turning back to normal, although a bit pale. When he was finished in Devilman's place stood a muscular young man with an athletic build that most men his age dreamed of having. His amber eyes turned into a grayish blue.

His name was Gabriel Cain.

He was currently naked, due to his change into his demonic form and as he went down an alleyway clothes started forming around his body. When they were finished forming he was wearing a dark black leather jacket over a grey short sleeved shirt, with a black undershirt underneath, and wore dark black pants and black boots, the clothes that he wore before he changed.

It was then that he noticed that something was on his the sleeve of his arm. He carefully pulled the device off of his arm and narrowed his eyes at it. The device was in a shape of a bat and had a small blinking red light.

As he stared at the device for a moment, trying to figure out what it was, until an idea came to him about what it was, causing his eyes to widen as he quickly crushed it in his hand and ran as fast as he could.

Batman had placed a tracker on him.

He should've thought of the possibility sooner, but he never had to deal with a hero before. He would be hunted down now, like an animal.

When Batman arrived he looked around and saw no signs that the Meta-human was here, aside from a trash bin that was moved.

"Hey Bat's!" Robin yelled, getting the Dark Knight's attention. Batman walked over and saw in his hand the broken remains of the tracker that he had placed on 'Devilman' as he flew away.

"Looks like he found it, this so isn't aster," Robin said seriously, Batman grunting in agreement. He then sighed as he brought out his communicator and tapped the button on it, calling the Watchtower, the Justice League's main headquarters.

"Batman to Watchtower, I'm going to need call a meeting to watch out for a particular Meta-human," Batman said. He didn't know if this Meta would appear again in Gotham and if he did he would take him down, but if he moved on then it would be best to let them know about what this Meta-human could do and how he fought to have a better chance against him.

Not only that, but he would look into the victims. The way that he had talked about them not being Meta-humans and just regular people got to him. He sounded so sure of himself. A person wouldn't commit a massacre like that in broad daylight unless they were absolutely sure.

Gotham Estates

Inside an estate a man was watching the TV with rapt attention, paying attention to every detail that was said and the demons in the footage. He had red hair with a silver streak in it and blue eyes. He was wearing a red sweater underneath a black suit and dress pants with dress shoes.

This was Jason Blood.

"As you can see the person that had changed into this 'Devilman' fought like a demon unleashed onto the earth, like a blood thirsty monster that savagely ripped apart its opponents as if they were nothing more than a late night snack. This reporter wonders just who is this Devilman and why does he resort to such brutal and monstrous tactics, but most importantly is he a dark hero? Or is he a monster that does what he does for the thrill."

Jason picked up the remote and turned the TV off and then placed it back on the coffee table in front of him as he stood up and walked away from the television.

"Devilman," Jason muttered, to himself. He had heard the term somewhere before and read about it a well, but he couldn't remember where. He made his way to his personal library and pulled out several books and opened the first one on the stack.

As Jason read the books, hoping to find a clue to figure out what this Devilman really was he considered his options if he couldn't find a clue as to what it was.

Etrigan though was a different matter entirely. The person was similar to him and Blood, but unlike them the being had suppressed the demon on his own will and heart. He already had an assumption as to what the demon inside of him was, but he couldn't say for sure. Just because their forms were similar did not mean that it was HIM.

He hoped that it wasn't him. If his assumption was correct then he was not sure that he would him or the Justice League would be able to stop him if he ever gained control. He barely survived their first encounter.

For those of you wondering yes Gabriel is the Akira of this story, but this story s going to be mixed of the original and its several revivals and movies. Gabe isn't Akira he will have his own background.

Another thing is for the sake of myself i changed a couple of things in the Devilman Universe for myself I don't care if you if you don't like its my story.

Gabe held back against Batman and didn't kill him for several reasons. One he was a hero and he doesn't want to kill heroes. He doesn't want the league after him.

For those of you who are new to Devilman here is a list of his powers.

Super Strengh- Not really sure what his max is, but the guy could throw a train with several cars with no problem.

Super Durability

Fire energy from his hand

Call down electricity from the sky (I think)

Regeneration- Guy lost his arm once and came out alive and took a punch through his chest and was still kicking ass.

Size manipulation- Can grow to 20 meters tall.

If they're are certain powers that i missed Pm about it ok. I'm meeting my friend this weekend to talk and see if i missed anything.

Technically If if do continue this it would be a Devilman/Devillady/ Young Justice Crossover with possible other works of Go Nagi such as Cutie Honey and Mazinger Z. And would be completely different from Invasion.

He won't change every time, only when he has to for some heay hitters. He's perfectly capable of killing demons in his human form.

This was just to blow off some steam really and if this story is to be continued, depends all on you guys. So review and let me know if i should continue this or not.
