Disclaimer: I own nothing except the idea, I don't know who owns Danny Phantom, if there are resemblances to other stories they will either be credited or it is unintentional. There may be crossovers with DC, Marvel, Teen Titans, Bleach so on, I don't own them either, they'll mostly be one shot minor ones, except a few like Tony Stark from Ironman, and Teen Titans, which will stick around.

Note: Danny will still be Danny, just slightly more serious. There will be jokes and sarcasm and so on, Dani will be similar. The only time he won't act like this is when he's serious, which happen every now and then, or pissed. You're about to see why him pissed is not a good idea, just read and find out.

Legend

"What is love"-speech

'Baby don't hurt me'-thought

(In story author notes)

Across the world people were watching a live news feed. On it showed a young ghost in the shape of a 13 year old girl. White hair in a ponytail and a black and white suit with a stylized DP on her developing chest, if she were a few years older she'd look like a ghost model, even now she kinda did anyways.

She had been evading the G.I.W. for 3 days now but had been hit with one of their paralyzing ecto-blasters. Now helpless and being grabbed she said "Let me go or daddy will be mad." There was some fear in her voice and she was mystified why she said daddy. She had meant Danny. The G.I.W.'s laughed at her and said "you're a ghost; you don't have a father, or anyone else." They started dragging her away and yelled out on instinct, not considering what she said "DADDY HELP ME!" immediately after "OOOooOooOoooOoo" and a bunch of cars, people, and chunks of the ground and nearby building flew back, out of the dust 2 pairs of pure white eyes, glowing with power, were seen. (This is the ghostly wail, only slightly higher pitched.)

At the Fenton's, with the parents, they were watching the capture of the ghost girl. Jack was cheering the G.I.W. on, Maddie was analyzing both G.I.W.'s battle tactics and the ghosts power's and reactions.

On screen they had just caught the girl when she said something weird, her 'dad will be mad'? Jack laughed with G.I.W., but she wasn't so sure, ghosts can't have kids, but they could adopt, not out of caring but to further their own aims. Who might get mad at that?

When the girl yelled for help though she was about to dismiss it, then a horrible noise was heard. She felt like she knew that noise, however all thought stopped when she saw who, or rather what had made that noise.

At Sam's Tucker was hanging out and Jazz had been more or less forced there by her parents, the longer Danny was 'missing' the more they forced her near them. Of course she knew he was fine, he called her all the time, just not the others.

She was watching the news while the other 2 were kinda awkwardly sitting on either side of the couch. They were basically forced here to, after Danny left the 2 couldn't stop getting into arguments, it ruined and relationship they had beyond acutance's. She thought part of the awkwardness was their guilt but never commented; she didn't want to be here and didn't want to talk.

Then on the news came a live feed on the G.I.W. doing something right, this caught all of their attentions. Then the three saw the girl, she reminded them all of Danny. As they watched her get caught they all felt sympathy for the girl, however when she said something about her dad being mad they were confused. Could ghosts have kids? Apparently so.

As she yelled out for help the three could only feel sorry, they were about to change the channel, they didn't want to watch this. Then … then they heard an all almost familiar noise and saw eyes that seemed to pierce their souls, although Jazz didn't feel threatened unlike the other 2.

At an undisclosed location there were 6 people around a table, on the wall was the word 'Avengers' and on the back of each chair there was a personal symbol to the one sitting on it. The man with brown, spiked hair and dark eyes, sitting on the red and gold chair, all the sudden stopped the conversation "Shh, sh sh, turn that up Bruce." Gesturing to the muted TV, the guy in the neon green chair turned it up, it was a live news feed on a … ghost girl? The man in the red, white, and blue chair scoffed "There are no such things as ghosts."

At this point the first one to speak Tony, spoke again "Oh yes there is and if there messing with that one" que the girl calling for daddy "there messing with my friend Danny and are about to be in a heap of trouble."

Before any of them could react a horrible noise was heard over the TV. Tony spoke "there's my que, I'm going back home, that way if ghost boy, his horse, and daughter need me, me and Pepper will be there." The red, white, and blue one, named Steve, said "Can I come then?" He said it sarcastically not expecting the response from Tony, "If you hurry up? Yeah, you'll get along just fine with him, let's go cap-sicle. "

With that he left, Steve right behind him. No one heard him mutter "those fools made some poor life choices; I wonder if they'll live through this?"

{Now back to what you want, angry Danny.}

Out of the smoke, the first noticeable thing was a horse, one of 4. Its original name had been Famine, one of the 4 horses of apocalypse. Its brother and sisters had been the white female horse Pestilence, able to send out locus like bugs that ate at the enemies. The red female horse War, if any but its rider got near it they would be slashed, like the horse was constantly surrounded by hundreds of swords. The pale gray male horse Death, it ate at its opponent's energy, leaving them tired and useless. However this, once horse Famine, formerly Nightmare, now Thanatos, it ate. Its looks and what it ate depended on its partner; with Frightnight it ate courage, now it ate skill, although the skill would return after an hour or 2.

Now the horse was pure black and only had 2 fangs coming from the top of its mouth and no horn. Its eyes were pure white and glowed with power. The armor around its neck and chest had expanded; it now covered the whole back, the chest, and the top of his wings. His mane and tail of fire were both now pure white. The armor now a bright silver and on the front of its chest there was a circle of black, inside of this circle there were 2 white eyes and a white dual scythe bisecting them \ if you were to look at it and the longer blade coming over the top left and the smaller one under the right. Its black, armor covered, wings now had white veins going although them. The stomach was shrunken and only the armor covered the ribs. (The starved look is only ghost form, regularly it looks healthy.) The terrifying beast gave off a mixed feeling of death, fear, bloodlust, and hunger.

The rider was its polar opposite, and seemed to be its perfect match; he was every bit as terrifying as his horse. The first thing that was seen, besides THOSE eyes, was a dual scythe. Held out in front of him, in his right hand, one blade came towards the watchers; it was longer than the other blade, about a foot and a half long, and was over his heart, about 2 feet from his hand. The other blade was pointing away from them about 8 inches long and about 2 feet away from his out stretched fist. Most of it was the purest white, except for the sharp part of the blades; these were see-through colorless, perfect for confusing someone's sense of sight as it sailed towards you.

The rider's clothes were almost all white; the only other color was on his boots. Steel toed combat boots, the soles were black, as were a single jet of black flames on the back. His white pants were leather and just short of being skin tight. He had a skin tight muscle shirt that was, of course, white. On top of all of this was a pure white, leather trench coat, if he were standing it would fall to just below the ankle. Above the waist, on the inside of the coat, there were several chains keeping the upper body of the coat closed when fighting, flying, and so on. The hair was long and, again, pure white (seeing a pattern yet?) it was also spiked more than completely natural. The eyes were white, no pupil or iris, and glowed with power, his mouth fixed into a snarl that told those watching he was going to hurt them.

All over the world and the Zone, one name came to mind. No matter how much he changed it was undoubtedly HIM. Danny Phantom. This name came to everyone who knew him, except one. The moment he came into view Dani, still being held, immediately shouted "Daddy, help me, their hurting me." This caused those glowing eyes to immediately focus on her and her captors. While everyone else was still trying to comprehend what she said Thanatos tossed back and did his deep roar, Danny loosed his scythe and caught it so the smaller blade was only about and inch from his hand, both pairs of eyes still glowing, Danny's now narrowed in unconcealed anger. This picture would be imbedded in many of their minds for years to come.

Thanatos dropped back down and charged to the girl, Danny leaned forward, unaffected by the horse's fire/mane and the scythe scrapped the ground, kicking up a trail of sparks, it left an ugly scar in the earth where it had been cut. As several of the idiot agents jumped forwards the ghost-man's scythe flashed at inhuman speeds, cutting through his opposition and often leaving them lying down in pain, they never slowed.

Within 10 feet of the girl Danny made 2 daggers, about a foot long, out of his white plasma, he threw them with his left hand and impaled both agents through their stomachs. As they, and consequently the paralyzed Dani, fell Thanatos circled them. He folded his left wing while Danny extended his left hand and caught Dani; he pulled her in so the girl was curled up into his chest. In a tired, almost said voice she said, quietly though the news micks still heard her, "Thanks for coming Daddy."

Danny flashed her a smile and responded "Of course sweetheart, I'll always be there for you." Looking back up, smile gone, several of the idio-I mean agents … who am I kidding? Several of the idiots tried shooting the trio, Danny opened his mouth and a horrible wail came out, with that noise came white rings of power "OOOoOoooOoo." The shots burst in midair, everything behind them, including the agents, cars, and buildings, got blown away in a mass of rubble, dust, and humans.

"Thanatos, fly." Commanded Danny, complying and slightly disappointed that was it, the horse took off. Danny twirled the scythe in his right hand, over his head, the left hand still cuddling Dani. As it twirled they were covered in a sphere of white energy, clearly heard through it all was Danny's voice, however it was darker, promising pain to those who'd disobey it "Anyone who touches my daughter shall fall, next time I'll make your ear BLEED from you own screams." With that Thanatos once again roared and the sphere turned opaque and expanded. Everything non-organic was evaporated in the light, everything organic was thrown back with great force. (Bonus points for the reference.)

In an instant they were gone, nothing left but their destruction. The circle of destruction from their leaving was about 30 feet wide. If anyone had looked at the human damage reports several agents were now missing an arm, some had broken bones from being trampled or knocked back by the horse or sphere. One agent would never move from the waist down again, and every agent was hurt in some way. It was a miracle no one died, as the scythe seemed to freeze where it cut so those cut with it didn't bleed out, although this made the inflicted pain several times worse.

If someone told Danny this later? His response would be "the only reason I didn't kill and torture them was my daughter needed help, next time I'll take more time, I assure you."

{With Fenton parents.}

Jack stared at the screen in shock, 'How could they lose?' Maddie was having much deeper and meaningful thoughts, divided into 3 basic categories.

#1 the ghost boy had changed. Of course given enough time even a ghost could change, but not this drastically, this fast! Also he had been a ghost BOY, now a ghost MAN? Ghosts don't age like that. The color change was also surprising; most ghosts had a consistency in that department.

#2 the powers and skill he showed was amazing, far beyond what he had had before his disappearance, there had been reports on him but nothing concrete so nothing on his changes were noted. That being said though he had apparently trained and mastered, to a degree anyways, how to wield not just a scythe but an odd dual one as well, ride not just a horse but a flying ghost horse with a mean streak, create objects (the knives) out of his now white plasma, and use that thrice damned wail with ease.

#3 as mentioned to be able to make things out of his ecto-energy and its apparent change from green and rarely blue into a pure white. And he made solid things out of it and incorporated it into his style. Not only that but it seemed to even change his horse, which no one knew where it came from (except Danny, a few friends of his, and Frightnight know) and the 2 seemed to be in a good tandem.

{Sam's place}

The two late teens and Jazz stared at the screen in shock. THAT was Danny? Their Danny?

Sam) That was Danny? He was hot, and what was up with that white plasma and that horse? The horse seemed vaguely familiar and so did his scythe movements. What happened to his clothes? And why did he show up after almost 3 years of nothing?

Tucker) Danny, I thought something horrible happened to you, if your around will we see you soon?

Jazz) I have a niece? Oh he better have a good explanation for this or I'm kicking his ass, super human ghost powers be damned.

Needless to say none of their thoughts were very in touch with each other.

{Tony and Steve}

After the ghost trio left the screen on Tony's plane, how he got that Steve still wasn't sure, Tony started "See? I said they made poor life choices." Steve couldn't help but agree and said so "Yeah, pissing off anyone of that skill level is just stupid."

Steve waited a moment before asking "So … where are we going and why are we going there?" "Back home, like I said I'm friends with Danny, the guy on the horse, he once told me about this little girl, Dani with an I, and no he didn't name her, that he considered a daughter. He asked me to keep a look out for her; I told him I would if I could meet her one day. Between that and how rich I am and the technology I have I figure he'll come to me to help her and keep his promise, and so I can look into how she's been and any abnormalities she may have obtained."

Steve was impressed, and said so; his reply was "Why are you impressed? He's a friend, I don't have many, but I never abandon the few I have." Steve simply smiled and asked "Why are we going so slow then? I know this tin can go faster than this."

Tony smiled and hit the accelerator button on his seat and said "Hold on Cap, this is about to get bumpy." JARVIS "Mach 3 will be reached in 5 seconds."

{Danny}

As he flew Danny knew he needed to make a decision. Where to go, what to look for, and how to make Jazz not kill him. So he decided on going to his friend's place, Stark towers. Their he could get Dani healed, check on his theory with her, and maybe get Pepper's advice on Jazz. Dani stirred in his arms and muttered "Love you daddy." He just smiled, stroked her uninjured lower back and murmured "It'll be OK sweetheart; no one will touch you while I'm here." He guided Thanatos with his knees; it would take about 3 minutes to get there. He just focused on making sure Dani was comfy while Thanatos knew where to go.

There's the first real chapter, what cha' think? Good, bad, give me feedback and ideas. Until next time, thank you for reading, and I'll see you then.
