A/N: I have decided to start a Harry Potter and Devil May Cry crossover since I recently got the Devil May Cry HD Collection for the Xbox 360. It is an awesome game. There are three people in the first game that I think should become Devil Arms. They are Phantom, the bird guy, and nightmare. I shall have him acquire Cerberus, the basilisk, several oc arms, Fawkes, and Nagini. Dante, Nero, and Vergil are all alive and Harry's uncle figures throughout the series. I saw a really good power in a Naruto and Devil May Cry fanfiction that allowed the user to absorb the elemental affinity of a demon. Harry shall have all of the devil powers including my own creation that allows him to absorb low level demons for more health and a longer lasting Devil Trigger. He will also have a devil ability to mix devil arms for better effects. Harry will have his own guns, Risen and Fallen that will be able to take on the abilities of a Devil trigger form.

Phantom: fiery gauntlets like Dante's only they have a ranged attack that allows them to pull demons from the underworld and use them as magma bombs. The devil trigger state turns the gauntlets into a full set of reddish golden armor that increases stats by 300% and allows the guns to fire of glowing magma bullets that will scorch your opponent.

The bird guy (still not sure of his name, so if someone could review and tell me that would be great): two small daggers with wings imbedded as the design on its hilt that allow him to glide and give him a massive control over wind and electricity. The devil trigger state turns the daggers into wings that go onto his back and allow him to fly and then allow for a powerful ranged attack called electric feathers that send a storm of feathers reigning down on his opponent also stunning them. They also allow him to take two feathers form his wings and use them as daggers.

Nightmare: a small blade that allows for him to dissolve into shadows. The devil trigger makes him practically untouchable except by light based attacks which then do critical damage. The devil trigger turns his entire arm into the devil arm with dark lightning coursing all over his body.

Cerberus: a dual edged sword with one blade having one face etched on it and the other having two. The devil trigger turns Harry's entire body into the armor. The arms have claws like wolverine with gauntlets going up to his shoulder blade. His feet have boots on them that go all the way up to where the leg connects to his body with faces etched on both of them. The middle of his chest armor has a gigantic face that looks like a dog's (think Koichi's spirit evolution form in Digimon). Harry can also breathe fire in this form like the Cerberus can.

Miranda (Basilisk): It is like Ivy's snake sword. It can extend and reattach at will. It also gives the user snake-like abilities. Its Devil trigger turns the bottom half of the wielder into that of a snake's tail and allows the user to extend his limbs. Its Devil trigger allows for extreme flexibility. It also summons the legendary Kusarinigi, a legendary sword capable of cutting through almost anything with incurable venom that will kill the victim in less than an hour after he or she is stabbed by this fabled blade of death.

Drusilla: as you might have guessed it, I am using a Buffy the Vampire Slayer Girl. The form I have in mind for this is perfect. It is a scythe that jacks his opponents mind with illusions. The Devil trigger ability causes the scythe to grow longer, sharper, and faster. It also causes the thing hit by this scythe to attack anything nearby, even their own teammates.

Buffy (alternate dimension, vampire): the vampire slayer. It is especially effective against creatures with vampirism tendencies. It is a blade that is completely gold. The devil trigger allows for one hit kills against weaker creatures with vampirism tendencies.

Willow (alternate dimension, vampire): the vampire witch. She had the power to match Morgan Le-Fae in magic. She is a staff with a blood red core at the top. She allows for greater use of magic and magical enchanting. Her Devil trigger has the ability to max out his magic and make him untouchable through supernatural means but leaves him vulnerable to ranged non-magical attacks.

Shadowcat: formerly a human known as Kitty Pride, her death made her bitter enough to become a demon. She is a necklace that allows for temporary untouchability against non-magical attacks. Her devil trigger is an Egyptian necklace that allows the user to possess people and stick a hand through the targets body and rip out vital organs from her opponent. It also allows for minor invisibility to non-magicals.

Kara-El: formerly a superhuman with an array of abilities. She is a bracelet that allows flight, heat vision, health upgrade, defense upgrade, speed upgrade, and a strength upgrade. She has a weakness to magic and demon rocks. Her devil trigger seems to halt time she is moving so fast and gives the user a major strength upgrade that stacks with the previous one.

Shayera Hall: an alien. Her spirit now resides in a mace and although not technically a Devil arm she acts like one. The mace is unaffected by magical means and gives a strength boost. Her devil trigger form allows for wings with the same effect, but also is able to cut through diamond.

Pamela ivy: a human that was turned into a demon. She is a whip that allows control over plants and males. Her Devil trigger has the ability to turn the user plantlike and gives the user a higher affinity to plants. It also allows for high speed regeneration.

X-celerate: a female alien that was able to move at supersonic speeds. She is a pair of boots made of reptile skin. She has the ability to give the user legs a speed and a jump boost. Her Devil trigger allows for higher speeds and a higher jump able to get the user to otherwise unreachable areas.

Fawkes: Dumbledore's pet phoenix. It was given up and turned into a Devil arm as punishment for Harry's life after his trial. Its form is a sniper rifle (M21-EBR) that can shoot bullets at impossible speeds with unlimited ammo. Its Devil trigger changes it into Juggernaut armor with two pistols that can shoot at the same rate as the sniper rifle can.

Nagini: originally a snake with Voldemort's horcrux in it. She became a Devil arm that looks like a black armband shaped like a snake. It lets Harry have a higher Legillimens ability and allows him to summon snakes that aid him in battle. Its Devil trigger form allows him to summon a tidal wave of snakes that are all venomous. It kills all enemies in the area but Harry is immune.

Devil absorber: a special devil ability that allows Harry to gain the power of the Devil arm he has used in the past. Ex: elements, special attacks, or special effects.

Devil fusion: allows Harry to stack the effects of his Devil arms and use them at the same time. It makes the Devil arms much more powerful.

There will be more arms than this however this is all I can think of right now. Also I shall be taking down my poll on my profile and replacing it soon after that as I have decided to make this story and my Harry Potter and the Vampyre maximus my main fics with the others as side fics.

Disclaimer: I do not own Harry Potter or Devil May Cry. If I did I would be living the good life with a summer home instead of living in an apartment with my parents.

Unknown Place, 1991

Harry was walking back from his newest job in his new clothing. A pair of jeans and a black leather jacket with a biomass symbol on the back that he had gotten from James Howler, aka the second prototype. As he was walking he remembered his past…

Flashback

Privet Drive, Little Winging, United Kingdom; 1989

It was another usual boring day on the usual boring street in the usual boring neighborhood with the usual boring family that was called the Dursleys. Or at least, that is how it appeared. You see, Mrs. Petunia Dursley had a sister that was very unDursleyish. Her sister, Lily Evans, was a witch, and, according to the Dursleys, a freak. The way this ties in is because her and another wizard's, James Potter, son called Harry Potter, now nine years of age, was living with them as his parents had died when he was one years old.

Harry's parents were great wizards when they were alive. His mom was amazing at potions, charms, arithmacy, and runes. His father was great at transfiguration, dueling, and rituals. They were both aurors. His mom was an unspeakable while his dad was a head auror. But this was not the reason Voldemort targeted them. Oh no, the reason he targeted them was because of a prophecy that stated their or the Longbottom's child would have the power to vanquish him once and for all. Voldemort went there to kill the family but Harry's mom sacrificed her life to save Harry. No one knows what happened to Voldemort. Some say he died, some say he is a shade, some say he was never human enough to die, and some say that Harry destroyed his soul and turned his body into ash that floated away in the wind by the time the aurors got there.

The Dursleys couldn't tell the neighbors about this due to the fact that they did not want to look like freaks, so they did the next best thing. They locked Harry into the cupboard under the stairs and neglected and beat him. But, what the Dursleys didn't know was that today was the day they would get rid of the freak once and for all. For someone on a motorcycle was coming to get him and take him away for good.

The man was dressed in a red trench coat with bandages around his chest. He had blue worn jeans on kept up by a belt with two gun holsters on it. Inside the gun holsters were two guns owned by the man's mother. The right held Ivory and the left held Ebony. He had black boots on. The man had short, unruly, silver hair that went down to his neck. On the man's back was a giant sword called force edge. The sword was as huge as the man and that was saying something as the man was about six and a half feet. The sword was once wielded by Sparda, who was called the legendary Dark Knight by the demons he fought. The man's name was Dante.

Dante was here for a reason. He had went to a doctor and gave him his blood as he didn't want any more surprise descendants of Sparda coming to him as the first was evil when Dante first met him and the second was just a crazy party animal called Nero.

Dante had found out that he did, in fact, have another relative named James Potter. However, James Potter had died but left a single son in Little Winging. His name was Harry Potter.

As soon as Dante came to Little Winging, he felt the presence of Sparda's blood all throughout the city. He had asked around a bit and found out that Harry Potter lived with a family called the Dursleys.

Dante got out of thought as he came to a stop in front of the Dursley's driveway. He got off his motorcycle and walked up to the front door.

On the other side of the door, Mr. Dursley, a fat man with glasses who looked like a Walrus with glasses, had seen the headlights and was peeking out the window looking at the tall man.

Dante knocked on the door.

"Can I help you?" Mr. Dursley asked suspiciously.

"Yeah, are you the Dursleys?" Dante asked in his usual cocky manner.

"Yes, who wants to know?" Mr. Dursley asked a bit more suspiciously as a stranger had just walked to the front door and asked for them.

"Names Dante, Dante Sparda." Dante said proudly.

"I don't know a Dante Sparda, now leave." Mr. Dursley said as he tried to close the door only to find the guy's foot stopping the door from blocking his way.

"Huh, nice cozy place you got here, Walrus." Dante said as he walked into the place and sat down on the couch with his sword laying in front of him on the end table like he owned the place.

"What do you want?" Mr. Dursley asked/commanded him.

"A member of my Bloodline is in this house, I want him." Dante said.

"What the hell are you talking about?" Mr. Dursley asked him.

"I mean Harry Potter is part of my family on his father's side." Dante replied to Vernon.

"Hell no you can't take him. As long as he is here, we get twenty thousand pounds a month." Vernon replied.

"Hmph, like a Human can stop me from taking what I want." Dante replied coolly while placing his hand on his gun.

Before Vernon could even blink, the man's gun was right in his face stopping him from moving.

"You will give me what I want or I will shoot you through the head." Dante said aggravated at the man.

Vernon gulped audibly and moved out of the man's way.

"Good boy, now where is he?" Dante asked.

Vernon pointed underneath the stairs.

Dante cocked an eyebrow at where the man was pointing.

Dante walked to the door, lifted his gun, and blew the door off of its hinges. Dante then saw a malnourished child that was the size of a seven year old kid. The kid had broken glasses, unruly hair, and no muscles.

"Why are you here?" Harry asked, scared of the man who had so easily overpowered his uncle.

"To take you away from here," Dante replied.

Dante then picked the kid up and put him up over his shoulder after he knocked him out.

Dante then whistled and his bike came through the door. Dante mounted his bike and drove away…

Flashback end

Harry then saw what he was after: An army of Bloody Maris standing in front of him. Harry then smirked cockily as he pulled phantom out and used him. Harry then ran at them and ducked the throwing knives that one of the guys threw at him, put his hand into the ground, pulled out a demon and threw the body at them and wiped them out. Ah, yes… Phantom always was his favorite because as the old saying goes you never forget your first.

Flashback

"I hate you Dante!" Harry screamed as he was thrown off a blimp and into the ground from a plane for his first solo mission.

Harry was nine and a half years old when this happened. Dante just laughed at him while he fell. Harry hit the ground and groaned. Damn, I hate that idiot was Harry's only thought before he hit the ground.

When Harry woke he found a giant hole in the ground where he had fallen. Harry walked up and saw a very extravagant church in front of him. Harry opened the door and saw a red carpet leading to a spiked object. Harry walked up to the object and touched it, but he reared back as the object drew his blood. He heard a giant rumbling followed by a thud sound. Harry turned around to see what had happened.

Harry saw a giant spider with a face in the front of it and a scorpion's tail on its back. The part that shocked Harry was the fact that it was made of lava. Harry remembered what Dante said about this particular creature and knew immediately who it was.

"So, this is what disturbed my slumber. I thought I felt a big meal but I guess I was wrong as all I see here is a small snack." Phantom said.

"Yeah, well I wonder if there is a brain inside that gigantic skull in that big body," said Harry in an aggravated response to his words as he rapped his fist on its skull. "Nope guess not."

"You'll pay for that puny mortal!" Phantom exclaimed madly as he put one of his front limbs in the air and swung.

Harry, not expecting the movement, was thrown into the air, but regained his balance. Harry then unsheathed his practicing blade to stab him in the head, as that was his weak point. Phantom covered his head up with his tail and sent him into a pillar.

Harry regained his balance in time to push off and see Phantom charging up and blasting his attack at him. Harry swung his sword downward and reflected the blast back toward Phantom. It was a hit that did a good amount of damage. It left Phantom stunned.

Harry then ran at him with his sword in hand and swung it straight through his body.

"You have done it. You have killed me; even Dante couldn't do it that fast. Grrg, I'm dying and losing energy. I am going to turn myself into a Devil arm. Take me and use my power to vanquish your foes in a torrent of magma!" Phantom screamed as his body glowed in a white light so bright Harry had to shield his eyes.

After the light vanished, Harry saw two gauntlets that looked the exact same. They were black with what looked to be cracks filled with magma. Harry put them on and immediately felt knowledge flood his brain. The moves and abilities were:

Extra strength- the user is twenty five percent stronger than he used to be.

Extra defense- the user is two hundred percent more armored against attacks.

Regular fist=other guy has broken bones all throughout the arm.

Fire affinity- has a great control over fire and a miniscule control over magma that can be improved

Devil trigger- The whole body is covered in Black armor with cracks filled with what looks to be magma in it. The user also has limbs that look like long spider legs made of magma coming out the back and a scorpion's tail.

Tail burst- fires a smaller lava demon out his tail that looks like a ball of light. It is not as effective against other lava demons.

Fist fire-fires a laser of light from the fist gauntlets that is actually a small burst of lava from the underworld.

Stacked affect- turns the blade it is with into a blade made of magma.

Harry was shocked at its effects.

Flashback end

Harry smirked at his ability to destroy demons. Harry then hopped on used his motorcycle to drive down the highway back to his home, the Devil May Cry office.

A/N: I know this is a lot of flashbacks for one chapter, but bear with me people. There is a reason for this. The reason is so I get this out of the way right now instead of later.

Harry will be very godlike in this and will face Mundus on his own later on in the story. I shall have him acquire Mundus as well. You might be thinking that this is making him too strong but he will face demons and other villains later in the story as well.

I shall have him gain a blade every ten chapters if I can most of them based off characters in other places.

Like I said I shall try to update this fic every other week.

This is Harem Lord saying peace out and until next time!
