Plot: Howard Stark and Maria Stark had lived longer than just Tony's teens, and Tony got Stark Industries when he was twenty.

Maria Stark had lived longer than Howard after the plane crash, but not by much. The last gift Howard gave Maria before he went on to the Ghost Zone was a child, a half-ghost child, who Maria named Marcus Howard Stark.

Giving up the child to college friends, the Fentons, she killed herself. But before that, she told them that Marcus was half-ghost. Jack and Maddie made a medication to suppress the half-ghost inside of Marcus- who they dubbed Daniel James "Danny" Fenton.

Flash forward fourteen years, and Danny had the portal accident. In the beginning, he thought the portal half killed him. In reality, the portal did not kill him at all. It fried his medication, freeing his ghost half.

Telling Jack and Maddie about it, they explained to Danny that he was not really Daniel James Fenton. He was actually Marcus Howard Stark, half-ghost son of Maria Stark and Howard Stark, and half-ghost younger brother of the famous Anthony Edward Stark.

Tony knew about Danny. He knew that his mother had lived and had Danny. So when Jack and Maddie ask him if he wants to meet Danny… Well, he prepares a room and everything. And then… The events of Iron Man happen. And all the other movies.

Author- Just me, Kyler Brennan.

Disclaimer- I own nothing but the plot.

Other Stuff- Wow. Didn't think I'd get this out as quick as I have, but here we are! I'm going to try to be better with this. Way better. This is also going to ignore some things. Like how HYDRA had Tony's parents killed. Because the car crash wouldn't work with this. Not at all. Also, things will change from the original story, but don't worry, I think you guys will like it. I hope. Otherwise, I'm totally screwed. Though the timeline is already fucked up as it is. Anyways, enjoy reading!

Chapter One

The Accident


The FentonWorks Laboratory was lit up like a Christmas Tree. It was the day after the Fenton Ghost Portal had failed, and young Daniel "Danny" Fenton had brought his friends, Tucker Foley and Samantha "Sam" Manson, down to the basement lab to check out the portal.

Danny Fenton was a pale-skinned, lanky, fourteen-year-old boy with shaggy, jet black hair and stunning sky blue eyes. He wore a white shirt with red trims and a red oval on his chest, along with jeans and red and white converse sneakers. He loved space and wanted to be an astronaut when he grew up. If you looked in his room you could see NASA posters, space posters, model rockets, and a lot of other space-themed items.

Tucker Foley- or T.F. as in Too Fine, as he liked to tell the girls he hit on- was an African-American Technogeek. He had turquoise eyes that were framed by glasses and black hair that was always covered by his red beret. He wore a yellow shirt with green cargo pants and brown boots. He was a meat-eater and always seemed to have a PDA in his hand.

Finally, Sam Manson, the only girl of the group, was a goth. She had black hair and amethyst colored eyes. Her hair always seemed to be up in a pony-tail. She wore a crop-top black shirt with a purple oval on it and a black and green plaid skirt, along with her famous combat boots. Calling her Samantha was a surefire way to get a combat boot between the legs. She was an Ultra-Recyclo Vegetarian, meaning she wouldn't eat anything with a face on it.

Sam had dared the boy to go into the portal, just to check it out. Maybe see if he could fix it. After a bit of coaxing, Danny put on a white and black HAZMAT suit and went in.

If only he knew how much his life would flip upside down when he entered that portal.

Tripping on a wire, he tried to grab something on the wall. Instead of grabbing something, however, he felt something give under his hand. After regaining his footing, he noticed that it was the "ON" button that he had pressed.

With wide eyes filled with horror, he tried to make his way out of the portal as it started to hum and glow, but it was too late. He was caught inside the portal as it started up.

His screams of agony were heard throughout the basement- possibly throughout the house- and all his best friends could do was watch in horror, their mouths left agape.

"Danny!" Sam screamed, almost making a break for the portal. Tucker stopped her, however, by grabbing her by the arm.

The portal sparked more, and Danny's screams of agony increased. "Sam, look out!" Tucker yelled, pushing her out of the way of the portal.

The portal suddenly spit out Danny, who was encased in bright green energy. Danny hit the wall, then landed on the floor with a THUD! But he wasn't the same Danny that went into the portal.

Instead of black hair, his messy hair was as pure white as snow. If his eyes had been open, they would no longer be the stunning blue, but an eerie toxic emerald green. His suit was no longer mainly white. The colors had inverted, leaving the suit mainly black. His skin was tanner than before and there was a white aura surrounding his body.

"Oh my gosh, Danny!" Sam screamed, racing toward him. Tucker followed suit, eyes wide.

"Kids!? Are you alright!?" A female voice was heard from upstairs.

Tucker was hyperventilating, as Danny twitched with electricity. He was scared to even touch him. "Dude, dude, no. You can't be dead! We've never went on a double date with twin cheerleaders!"

Danny twitched, and his eyes opened and closed drowsily. "I'm not dead… Can you keep it down, Tuck..." He slurred out, collapsing to the ground. He twitched again, and bright blue/white rings of energy washed over him, transforming him back into a human, to Tucker and Sam's complete and utter shock. A sigh escaped his mouth as he started to drift into unconsciousness.

"No, no, no… Danny… Don't go to sleep…" Sam muttered, shaking him slightly, trying to keep him awake.

"Dude, don't go to the light!" Tucker yelled, as Maddie raced down the stairs to see her son, on the floor, sparking with electricity. His eyes were dulled down, and his breathing was slow. His skin was much paler than normal.

When he sparked again, Maddie couldn't help but faint.

"Mrs. Fenton!"

Jack came running down afterwards, and immediately, he called two numbers. 9-1-1. And, the number of a certain Anthony Edward Stark…


Tony was in his workshop in his Malibu mansion, working on one of his many cars, when he got the call from Jack. His music was blaring through the speakers, but it was turned down quickly so that his AI could communicate with him.

"Sir, a 'Jack Fenton' is trying to reach you via the telephone," the British-English voice of the AI Butler, JARVIS, said.

Anthony Edward Stark, more commonly referred to as Tony, jolted under the car. He knew where this was going to go. "Answer it, JARVIS," he said, pushing himself out from under the car.

Tony Stark was a muscular man, thanks to the years working with weapons and other technology. His hair was short and black, and he had a nicely kept goatee. He had a fair complexion and brown eyes. He wore a t-shirt that was covered with grease stains, and his jeans were in the same state. He had sneakers on, as well.

"As you wish, sir," JARVIS replied briskly.

"Mr. Fenton, what's wrong?" Tony asked as soon as the call was patched through.

"Danny… Got electrocuted by a ghost portal. It seems to have activated his dormant… Ghost…" Jack said. His tone was filled with worry for his only son- adopted or not.

"And what do you need from me? I know nothing about ghosts or biology, and Stark Industries is a weapons manufacturing company. Can't help there," Tony replied. He didn't want to have to drag Danny into all this. He knew why Jack was calling, but he was only playing dumb, trying to prolong the inevitable.

Danny deserved a life better than the one Tony had growing up. Which is why, when Tony started running SI, he had left Danny with the Fentons. Plus, he had no experience raising kids and he didn't want to rip Danny from the only family he had known. Despite what the media showed, Tony Stark did care about people other than himself.

"We might need help… Explaining who he really is," Jack answered. "That, you can help with."

"What do you need in that department?" Tony asked with a soft sigh, knowing he would have to head to Amity Park after this.

"Practically- everything."

"Alright," Tony nodded, though Jack wouldn't be able to see it. "Anything else?"

"We'll see once you get here," he answered.

"See you then, Mr. Fenton," Tony said, hanging up. He got up, wiping his greasy hands off on a nearby rag. "JARVIS, call Pepper and tell her to reschedule all meetings for the next few weeks. And jet the jet ready. We're going to Amity Park."

"As you wish, sir," JARVIS replied as Tony got ready to go to meet Danny.


Danny sat in a hospital bed, wires hooked up to him. The doctors just left, and were now allowing him to have visitors. Maddie and Jack walked into the room, followed by Sam and Tucker.

The hospital room was obviously made for younger children in mind. It had a large window for one wall, and a painting of a friendly forest across from the bed. A flatscreen TV was attached to that same wall. The bed had white sheets with an orange blanket and there were a few chairs near the window. About a foot away from the TV was a whiteboard with the names of the nurses and doctors working that day, with markers to the side of it attached with Velcro.

He was staring at his arm, watching as it turned invisible, then visible again, then he looked up at his parents. "Daniel James Fenton… What did you think you were doing?" Maddie questioned.

"I- I was trying to fix it…" He replied, frowning. "I did… It just hurt. A lot."

Maddie frowned, and Sam and Tucker really wanted them out of the room so they could tell Danny what they saw.

"I had a weird dream after I passed out," Danny explained. "I was… Tanner. I had white hair. Green eyes. I wore a black and white jumpsuit- inverted colors of the one I was in… And… I was flying."

Sam's eyes widened with chock. "That's- that's-"

"Dude! That's what you looked like when you came out of the portal!" Tucker exclaimed, picking up where Sam had left off.

"Wait… What!?" Maddie, Jack, and Danny all questioned.

Danny paled, and then… His legs just vanished into thin air.

"Oh my God… Jack… It's happening," Maddie whispered.

"What's happening?" Danny questioned in shock and fear, staring at where his legs were supposed to be with eyes as wide as dinner plates.

The door opened right after that. "Well… Lets just say that genes don't like to be suppressed," a male voice said and Tony Stark waltzed right into the room. He looked at Danny, then at the other occupants in the room. "Pesky little things, genes are. But they also make us who we are, so..."

"That's- that's- you're Tony Stark!" Tucker sputtered out.

"That I am," Tony said with one of his charming, media smiles, before turning to the Fenton Family. "Hello Mr. Fenton, Mrs. Fenton, Danny," he greeted curtly, deciding to lean against the wall. "I want to start by saying that this was all done to protect you," he started. Then he sighed. "No, I'm not your father. God, I hope I don't have a kid anytime soon… Anyways, you're my younger brother. Contrary to popular belief, only Howard Stark died in the plane crash. Maria Stark was still very much alive. But, from what I understand, Howard couldn't stay long. So they kind of… You know… And Maria hid from the public for nine months, until you were born," he explained, not meeting anyone's eyes. "She gave you up to some college friends- the Fentons- right after that. She didn't want to be without Howard and she..." He stopped there.

Danny's eyes widened, and his mouth was open with shock. His eyes were bright green, and his arms were visible again.

"Danny?" Sam asked, poking him to try to get a response, but he was in a state of shock, and didn't feel a thing.

"Before mom decided she wanted to be with Howard and not alone, she gave you a name. Obviously you didn't keep it, because then you would have been hounded by the press," Tony continued.

"What- what's my… Real name then?" Danny asked.

"Marcus Howard Stark," Tony answered seriously.

Danny nodded slowly, before falling through the bed.

"Danny!" Sam and Tucker yelled.

"You alright, kid?" Tony asked, trying not to appear shocked. It wasn't working. At all.

He climbed out from under the bed, and nodded before he started floating up to the ceiling.

Sam looked up, and slapped herself in the face before jumping up and grabbing his shoe, dragging him back down to the ground.

Tucker looked toward Tony. "Anyways… I can't believe I'm best friends with the brother of Tony Stark! I'm a huge fan! Sign my beret?" He pulled off his signature red beret, holding it out towards Tony.

"Uh…" Tony looked at the star-struck teen. "Alright," he finally said, taking a marker from a whiteboard in the room and grabbing the teens hat. He signed his name on the front of the beret and handed it back to Tucker. "Enjoy, kid."

Tucker grinned as he clutched the hat. "Thank you!"

"Tucker, don't fangirl. Just don't," Sam said, which seemed to offend Tucker.

"Hey! I'm a dude, not a girl!"

"Fine. Don't geek," Sam remarked.

Maddie looked at Danny. "And Danny, sweetie, you're going to go with Mr. Stark for a while," she said.

"Wait, what?" Both Tony Danny exclaimed with surprise.

"I don't think that's such a good idea, Mrs. Fenton. My PA says I barely take care of myself, as does my own AI! Not to mention that I'm a weapons manufacturer," Tony argued. Not that he didn't want to spend time with Danny, but he had the Jericho presentation coming up soon and he couldn't just bring Danny with him.

Maddie glared at him for a second.

Tony looked like he wanted to argue more about it, since he was an alcoholic, not home very often, a playboy who always brought girls home for a one-night stand, and generally a horrible role model, but the glare made him think twice about it. "Actually, maybe it is a good idea," he gulped. "Let me just go make some calls…" He took out his phone and rushed out of the room.

"But- but- mom! I hardly know him!" Danny said as soon as Tony was out of the room, and out of earshot.

"That's the point. You need to bond with your brother, Danny," she said in a tone that only a mother could pull off. "No buts about it."

"But-"

"I said, no buts about it," Maddie repeated.

"Yes ma'am..." Danny admitted, defeated.
