Fugitive Demigods || A Percy Jackson // Advengers crossover

The room was tense.

Nick Fury stood at the head of the table, arms crossed, his one eye scanning the gathered Avengers. The interrogation results—if you could even call them results—had been laid out in front of them, but they didn't paint a clearer picture. If anything, they only made the situation worse.

"They're impossible," Natasha said, her voice edged with frustration. She flipped through the interrogation notes again. "Not a single usable detail. Everything they said was either a joke or complete nonsense."

Steve frowned. "We're sure they aren't just being difficult?"

"They are being difficult," Tony said, rubbing his temples. "Jackson spent half his session flipping over furniture, refusing to answer questions, and asking for blue soda. I'm still not over the fact that he blamed missing DNA on drugs."

Bruce adjusted his glasses. "But it is strange. Their genetic tests show gaps that shouldn't be possible. We've seen genetic tampering before, but this isn't that. It's like half of them just... isn't there."

Thor, who had been silent up until now, leaned forward with an unreadable expression. "It is not mere absence. It is something beyond your understanding."

Fury narrowed his eye at him. "You keep speaking in riddles, but you seem to know something we don't."

Thor merely grinned, but said nothing.

Fury sighed and turned to Clint. "What about their records?"

Clint exhaled, looking over a different set of files. "We got their history—what little of it exists. The problem is that every record on them is a mess. It's like someone went through and erased, altered, or covered up half their lives. Jackson has more reports filed under missing persons than should be legal, and Chase? Her family is listed as 'deceased,' except that there are contradicting reports that her father and stepmother are still alive. La Rue's past is the most straightforward, but even that has weird gaps."

"They're ghosts," Natasha muttered. "Ghosts with extensive records in terrorism, destruction of public property, and—" she paused, flipping through a page. "Seriously? Theft of a police car?"

"That one was Jackson," Clint added.

"Of course it was," Tony said dryly.

Fury pinched the bridge of his nose. "We've been running in circles with these three since the second we picked them up. They're suspects in the murder of two civilians, they have a rap sheet longer than Stark's shopping list, and yet we still don't know what the hell they are."

Right then, the door swung open.

"Uh, sorry I'm late," Peter Parker said, stepping into the room, a backpack slung over one shoulder. "You guys needed me for—" He stopped mid-sentence as he caught a glimpse of one of the files lying on the table. His entire body stiffened. "Wait. Percy Jackson?"

The room turned toward him in unison.

Fury narrowed his eye. "You know him?"

Peter blinked. "Uh... yeah?" He scratched the back of his head. "Well, kinda. We went to the same school. I was a freshman, he was a senior."

Tony's eyebrows shot up. "You went to school with Captain Blue Coke?"

Peter nodded. "Yeah, I mean—he was kind of a legend. I didn't know him well, but everyone at Goode High did. He was that guy who somehow managed to be both the most popular and the most terrifying student at the same time."

Clint leaned forward. "Terrifying how?"

Peter hesitated. "Well... he, uh, kind of had a reputation? People said he was in a gang or something."

Natasha raised an eyebrow. "A gang?"

Peter quickly shook his head. "I don't think that was true! But he was always getting into fights. And I mean bad fights. People would try to mess with him, and then suddenly, boom—someone's in a trash can."

Clint let out a low whistle. "I like this kid already."

Peter made a face. "It wasn't just that, though. People disappeared around him. Like, we had this one teacher? Real creep. The guy vanished in the middle of the semester, and Percy was the last one seen arguing with him."

Steve frowned. "And no one investigated?"

Peter shrugged. "They did, but nothing came of it. It was weird. Stuff like that happened a lot. People went missing, and somehow, Percy was always nearby. But there was never any proof."

Fury's expression darkened. "Interesting."

Peter glanced at the files again, his eyebrows furrowing. "Wait. What's going on? Why do you guys have files on him?"

Tony sighed, gesturing at the table. "Congratulations, kid. Your old classmate is currently our top suspect in a double homicide."

The tension in the room thickened as Peter Parker stood there, his eyes flicking between the gathered Avengers and the thick file labeled PERCY JACKSON spread open on the table. The more he saw, the more uneasy he felt.

Percy—murder? No way.

Sure, the guy had a reputation. But this? Something wasn't adding up.

Fury fixed his one eye on Peter. "So, tell us everything you know about Jackson."

Peter shifted uncomfortably. "Uh... well, like I said, we weren't close, but everyone at Goode knew him. He was kind of famous, but not in a 'star quarterback' kind of way. More like a 'don't mess with him unless you want to regret it' way."

Natasha leaned forward, arms crossed. "Elaborate."

Peter scratched the back of his head. "I mean, he was always getting into fights, but never for himself. It was usually because someone messed with his friends. If you went after someone he cared about, it was over for you. He wasn't just strong—he was scary about it. He'd warn people first, and if they didn't listen... well, they usually ended up in the nurse's office."

"Loyal, then," Steve noted.

Peter nodded quickly. "Extremely. Especially to his girlfriend—uh, Annabeth? They were basically inseparable. Like, people joked that if you hurt her, you might as well dig your own grave."

Tony snorted. "Oh great, he's one of those guys. Protective boyfriend type."

"No," Peter corrected, "it was more than that. It wasn't just her—he had a whole group of people he was protective of. I heard him mention a bunch of names over the years—Annabeth was the big one, but also Nico, Will, Piper, Jason, Thalia, Frank, Hazel, Leo..."

Peter frowned as he saw a few of the Avengers exchange glances at some of those names.

"Wait," he said slowly, "you guys know them?"

Fury's face remained unreadable. "What makes you think that?"

Peter hesitated, but then shook his head. "Never mind. Anyway, the point is—Percy isn't the kind of guy who would just murder two people for no reason. If he did do something... then either they weren't innocent, or something really, really bad happened to push him that far."

Natasha sighed. "That's what we're trying to figure out. But he's not exactly forthcoming."

"Yeah, well," Peter said, crossing his arms, "if you're treating him like a criminal, he's definitely not gonna talk to you."

Fury studied Peter for a long moment. Then, he smirked.

"Good," he said. "Then maybe you can get him to talk."

Peter froze. "...Wait, what?"

Tony clapped a hand on his shoulder. "Congrats, kid. You just volunteered."

Peter had a sinking feeling he'd just walked straight into a mess he wasn't ready for.
