Alright, I feel like I have to explain things.

I didn't like how the other Thor Junior I was writing went, so I deleted it and now I'm redoing it. Nothing major with plot changes, just polishing up a few details. The later chapters will really get a hit thought, so be prepared. Oh, more demigods are going to be missing too, along with Percy. Suspense!

Disclaimer: I don't own Heroes or Avengers, marvel and Rick Riordan do.

*Stark Towers, New York, an hour after previous events*

Tony POV

"I still don't see what the big deal is?"

Everyone looked over at him with harsh looks, and all he could do was shrug and prop his feet on the table. Steve gave him a disapproving glare, but Tony smirked and asked "What?"

Fury scowled at him with his one eye and said "The problem is, my sources tell me there will be war in two weeks, and only this guy can possibly help stop it. These disturbances are obviously important."

Tony shrugged again and said "We handled the alien invasion in New York; I don't see why we need some guy's help that we don't even know."

Bruce looked from him to Fury as if watching a tennis match. Steve gave him a reproachful look and Clint and Tasha weren't even paying attention to Tony, eyes remaining on Fury with unbroken concentration.

Thor seemed the only one excited for the guy's introduction to the team.

"Jason Grace fury, the Jason Grace?" he asked.

Fury nodded and Tony asked "Why is this guy more important than me? I bet I can beat him with one arm behind my back."

Thor only smiled and shook his head, as I he knew something Tony didn't.

And Tony knew a lot more then Goldilocks.

Fury shook his head and said "Look, it's out of my hands, and this guy's coming anyways. It's only two weeks, and I would appreciate it if you didn't try to kill him before he's been here five minutes."

Tony smiled and said "I'll try. No guarantees though, he might be a bit stuck up."

"Like someone else I know." Fury deadpanned, looking pointedly at him. Tony shrugged and lowered his feet from the table.

"Sir, someone claiming to be Jason Grace has asked to come up." Jarvis called from the roof.

"Bring him up, I want to check out the new meat." Tony said.

Natasha looked over at him and said "You do know that that sounds really immature, don't you?"

Tony grinned and said "This is going to be fun."

The elevator dinged and everyone's heads turned and watched the guy approach. Tony almost laughed out loud.

This guy couldn't be older then sixteen, with close cropped blonde hair and blue eyes, a little scar on his lip. He was reasonably muscled, but not overly buff, with an overnight bag slung over his shoulder.

He raised a hand in greeting and said "Hi."

Fury studied him and asked "You cannot be serious."

The kid looked over at him and asked "Sir?"

Fury shook his head and said "This man expects me to stop a war with a kid? You probably don't even have a driver's license."

The kid frowned and asked "What, the Olympians didn't tell you who I was?"

Everyone gave him curious looks.

"Who are the Olympians? Some sort of company?" Bruce asked.

The kid shook his head and said "No the Olympians, as in Rome. Jupiter, Pluto, Juno, you know?"

The sky rumbled outside, lightening crackling in the distance. Thor glanced outside and merely shrugged.

"Wait, you're telling me you believe those ridiculous myths? Ha, this kid's a joke!" tony said, laughing.

The kid frowned and dropped his bag.

"They didn't explain anything? Me, my life, the other side of humanity? Pluto, I should have known they would pull something like this."

He groaned and asked "Which one of you is the Director Fury?"

Fury raised an eyebrow and asked "I am young man."

The kid nodded once, seemingly unfazed by the one eye and reached for something from his bag.

"If you see a sword, raise your hand." The kid said.

"Why would you have a- Holy shit?" Tony shouted.

The kid drew a huge, golden, razor sharp sword from his bag, and swung it in easy circles. Tony watched the glittering point and felt suddenly very nervous. He looked way more than capable of making a Stark-kabob.

"Where the hell did you get that?" Tony demanded. Everyone backed away quickly, Clint and Tasha drawing guns from almost nowhere. The kid raised his hand and said "Easy, lower your weapons. Alright, everyone's clear-sighted. That's a good sign."

"What the blazes does clear-sighted mean?" Steve demanded, relaxing slightly when the kid sheathed his sword, but remaining alert.

"It means you can see through the Mist. It's a magical veil that hides monsters, gods and other magic stuff from mortals." He pointed at them. "This is good; there might be monsters in the army."

"Monsters?" Clint asked a smirk on his face "like the boogeyman? Or werewolves?"

Tony smirked and asked "Is count Dracula coming to suck my blood? Please kids, let the people overage act like adults."

The kid raised a hand, a little frown on his face and said "Let me explain better."

He sat down and said with the most serious look on his face "You know the gods from Roman myth, I assume. Well, they didn't fade when the Roman Empire ended. They moved, along with Western civilization. Right now it's in America."

"There's no such thing as gods and monsters." Tony said, sitting down in a chair. "They don't exist. They were what ancient people used to explain science."

The kid shook his head and said "I'd keep quiet before you offend one of those gods. Especially Jupiter, and Neptune isn't in a pleasant mood at the time."

Tony laughed and said "I can insult them all I want because they don't exist!"

He turned to the window and to prove his point shouted "Neptune wishes he was blind, having to look at Jupiter all the time. And Jupiter wishes that his mom gave him the brains they gave a peanut!"

The sky shook and rumbled with thunder, lightning bolts lighting the charcoal grey sky. One bolt would have gone straight to his heart had the kid not jumped forward and shoved him back.

"He's not a believer, he's just getting used to it!" the kid shouted at the sky, waving his arms wildly. The sky calmed a bit, but thunder still boomed in warning.

Surprisingly, Thor said "It would not be wise to anger Neptune or Poseidon at this point friend Stark. Nerves are wearing thin with the looming war."

Tony laughed and said "you believe this guy?"

Thor nodded and said "I have met his father personally. And young Jackson's father as well."

The kid immediately had a stone face, expressionless and empty. His clenched fists shook for a second before saying "don't say his name."

Thor bowed his head and said "My apologies young Grace. I had not realized the Greeks and Romans were on speaking terms."

The kid took a deep breath and nodded.

"Grace, continue with your history lesson." Fury said, sitting down again.

The kid nodded and said "well, in myth, the gods always went and, went out with mortals. And then the mortals had kids. Demigods, half human, half gods. Heroes, half bloods, monster lunch."

"So you're saying you're a demigod." Clint said.

"Son of Jupiter, former praetor of camp Jupiter, bunch of other titles." The kid said.

The room was quiet until Bruce asked "Saying this is true, what does it have to do with you and this coming fight?"

Well, demigods are hunted by monsters, and when the demigod kills the monster, they go to Tartarus, the abyss. All the monsters go there when they die, then they reform. Well, Tartarus is stirring. Monsters are coming back faster and starting to cause problems in the mortal world. Tartarus is waking, and he wants revenge for his wife, Gaea, who we beat last summer." The kid said.

Everyone was quiet.

Tony stood and brushed off his jacket, and sat down in a chair.

"Why should we believe you?" he asked.

The kid turned and asked "What?"

"You're a kid, some random guy I've never met, and you're trying to get us to swallow this huge story. Say it is true. Prove it."

The kid frowned and said "You don't believe me, that's your problem. I'm a demigod, and if I'm here for too long, monsters will smell me and come here."

Surprisingly, again Thor said "He tells the truth friend Stark. These demigods are fearsome in battle, and the gods do exist in this world. Greek and Roman sides."

"Yes, but I need solid proof. The council won't believe this if I just go spouting some nonsense about gods and monsters." Fury said.

He towered over the kid and said "we need proof."

The sky thundered loudly outside.

The kid stood and asked "You want proof?"

He walked to the window, drawing his sword. He held it high and shouted "Stand back!"

The sky swirled outside, the clouds forming a dark grey funnel in the sky. Lightening flickered, and a massive bolt streaked from the sky, striking the tip of the golden sword raised above the kid's head. The sword was crawling with lightening, zapping and flickering with blue energy. The kid swung the sword around twice and pointed back at the sky. A massive blast echoed to the room, and the air pressure forced everyone to the ground. The bolt zigzagged into the sky, disappearing into the clouds.

The kid sighed and lowered his sword, leaning on the table.

The kid turned back to them, his eyes accusing.

"Well?"

Bruce looked up from the ground and said "I believe you."

Fury nodded and the spies half a heartbeat after him. Steve nodded and Thor laughed, the only one still standing other then the kid.

Tony thought for a second before snapping his fingers.

"You'll be Thor Junior!"

The kid frowned and asked "What?"

"Your nickname. Everyone's got one. Captain hook, Capsicle, Big Green. Thor Junior."

Steve shook his head hopelessly and the kid half grinned.

"Anything's better then Sparky I guess."

After everyone was seated again, Fury asked "so what can you tell about the war. How strong is this Tartarus character?"

Jason looked down at the ground and said "He's a primordial, more powerful then the gods, titans and giants. He's more powerful then any of us combined. Only Annabeth and Perce,"

Jason paused and swallowed and said "and Percy have every actually seen him in a somewhat physical form."

Steve said "Well, let's bring these guys in and get some information."

Jason lowered his head and said "Annabeth won't talk to anyone about Tartarus without Percy, and he's been missing three weeks. No one knows where he is. Neptune's going crazy not looking for him."

Fury scowled and Tasha asked "We could get this Annabeth girl to talk. SHIELD is good at that."

Jason shook his head and said "Tartarus drove her half insane. She's obsessive, doesn't eat or sleep, and if you get her a little pissed, its all downhill from there. With Percy missing, it's only getting worse."

Steve looked trapped in his own dream land, eyes distant. Fury was scowling, and Bruce thinking hard. The master assassins were watching impassively. Tony frowned and asked "Well, if this Annabeth chick won't talk, we got to find this Percy guy."

Jason shook his head and said "Was driving to camp and vanished from the car. We found it abandoned on the road when we went to find him. No blood, no claw marks, no poison stains, nothing.

"Jarvis," Tony called out to the AI "Search this Percy guy and run facial recognition scans across the planet."

Jason looked at him like he was crazy before the AI responded "Right away sir."

"What the Pluto is that?" the kid demanded, jumping a little

"Jarvis, artificial intelligence butler system I installed." Tony said dismissively.

Jason nodded, glancing at the ceiling.

"Sir, no facial recognition for anyone named Percy. It seems he has vanished off the face of the planet." Jarvis said.

Seconds later, Jarvis said "Sir, there appears to be several energy readings popping up in Central Park. Over fifty."

"Jarvis, get cameras on the scene." Fury barked.

"Right away Director." Jarvis said. Half a second later, the small screens around the table flickered to life to show something Tony couldn't believe. Any doubt that Jason was lying had disappeared as the screen came to life.

What looked like several giant ogres were crashing along the paths. People were screaming, and what looked like pretty girls and half goat half human guys were trying to throw acorns at them. Weird snake women were among the ranks, and half seal half dog monsters too.

"The tree nymphs are fighting? Coach Hedge said they try and never fight?" Jason said.

"Who?" Bruce asked, but was silenced as one ogre threw a bronze cannonball. It burst into green flames and the girls and goat men screamed.

"We have to help." Jason demanded standing and drawing his sword "They're looking for the Central Park entrance to the underworld."

"Where?" Steve asked.

"Never mind that. Come on, they're dying out there." Jason said. He ran to the window and jumped. Tony half expected him to be dead.

"Jarvis, armor!" Tony shouted. Gears popped as the walls opened up and the armor put itself together.

Steve grabbed his shield form under the table and Fury said "Get to the hangar. Stark, get the kid."

Tony sighed and jumped to the window in full Iron Man mode. The kid was flying low to the ground, like some kind of blonde superman.

"Wait up Superman, leave some ugly monsters for me!" Tony shouted, flying after him.

Going to leave this chapter pretty much the same. Changed a couple words, a bit of editing. Nothing major. Also, who should be the next demigod to go missing? Trying to center around the seven more. Maybe a Roman. Open for suggestions.
