Lord Peverell

James Rhodes was a man of logic.

He believed in rules, in structure, in accountability. That was why he had supported the Accords—because superheroes needed oversight, and the world needed reassurance that they wouldn’t run unchecked.

But what Rhodey didn’t believe in was political games.

And somehow, somehow, in all the chaos surrounding the Accords, someone had played the system under their noses.

It wasn’t until after everything had settled—the rogue Avengers back in the Tower, pardoned, supervised but free—that Rhodey started digging. 

The Accords had been brutal when they were first proposed.

The restrictions, the oversight, the control—it had been an ironclad contract. And yet, by the time they were enforced, they had changed.

Radically.

The rules were still there.

Superheroes had accountability.

But they weren’t under complete government control.

There were emergency clauses, independent oversight instead of direct political control, protections against wrongful persecution.

And the rogue Avengers— They hadn’t even needed to stand trial. Their records had been quietly adjusted. Pardoned.

It had been too clean. Too precise.

And when Rhodey finally traced the changes back, all he found was one name. Peverell.


Lord Peverell was a ghost.

No pictures, no public appearances, no clear identity.

But he had power.

Rhodey had seen Tony go toe-to-toe with politicians and walk away the winner, but even Tony Stark hadn’t been able to get through the red tape of the Accords.

And yet, Peverell had. Without a fight that made it into the news. It had just... happened.

Quietly.

And then there was Bucky Barnes.

Steve had fought tooth and nail for Bucky’s freedom, but there had been no winning against the system.

The Winter Soldier had been a boogeyman for decades, and no one wanted to hear about brainwashing or HYDRA programming.

But then, out of nowhere, classified Russian documents had surfaced.

Testimonies from former Soviet officials. Proof of Barnes’ captivity, of HYDRA’s influence. And suddenly, the longest-held prisoner of war was exonerated.

Not long after, General Ross had been arrested.

The man who had spearheaded the most aggressive sections of the Accords, the man who had been pushing for enhanced individuals to be permanently detained, had been removed like a bad chess piece.


While Tony was still processing everything about his newly discovered son, he had unknowingly been under Harry’s protection long before they even met.

The Sokovia Accords had been a disaster, and while Tony had tried to work within the system, it had been messy.

The government had been rigid in its stance, and the divide between heroes had been deep.

Then, out of nowhere, an unknown but powerful figure had stepped in—Lord Peverell.

No one had ever seen his face, but his influence was undeniable.

It was through his carefully worded amendments that the Accords were softened. Under his influence:

  • Superheroes were granted operational freedom, as long as they underwent accountability training rather than signing their autonomy away.

  • The rogue Avengers, including Steve, had been pardoned under the condition that they work alongside the government in a supervised capacity rather than being fugitives.

  • Bucky Barnes had been legally declared the longest-held POW, which led to his criminal record being wiped clean.

No one knew who Peverell was.

But some suspected he was British, given his clear sway in the U.K.’s government.

Others theorized he was an aristocrat with old-money influence.

All they knew was that he had enough power to override decisions even the U.N. struggled to change.

(Well they would definitely listen when someone went and changed the whole wizarding world entirely in a year just after war without much blood shed.)


“You know,” Rhodey started, “I always thought some big-shot noble or politician saved our asses after the Accords. I didn’t think it’d be your kid.”

Tony blinked. “Excuse me?”

Rhodey gave him a dry look. “Tony I think Your kid is Lord Peverell.”

(someone give this guy a medal)

Tony snorted. “Right. My sixteen-year-old son is a political mastermind who reworked international law. You hear how ridiculous that sounds?”

Rhodey just folded his arms. “Yeah? So tell me why ‘Lord Peverell’ has no digital footprint, no public appearances, but somehow has more power than some powerful organisations? Sounds a lot like a certain paranoid teenager we both know.”

Tony hesitated. He had looked into Peverell before—everyone had. But there had never been any record of his face or age.

“… He might not be?” Tony muttered, rubbing his face.

Rhodey just chuckled. “Yeah. Maybe not. It does sound ridiculous.”

(Never mind)


Later that night, Tony watched Harry—his son—playing with Teddy and Delphine, effortlessly making them laugh, completely oblivious to his father's train of thoughts.

Tony muttered to himself. "Nah it can't be him....I hope."


It started with an offhand comment from the President.

"Your kid has a good head on his shoulders, Stark."

Tony had nearly choked on his drink. "what now?"

The President had only smiled. "Ah. I see he hasn’t told you. Figures. Lord Peverell prefers to remain unseen."

It couldn’t be.

The one credited with making critical amendments to the Sokovia Accords, securing pardons, and helping take down General Ross.

The one Governments acknowledged, feared him even, but no one had ever seen.

No. No way.

But then Tony turned to him, eyes wide with shock, and Rhodey knew they were both thinking the same thing.

Harry.

Harry freaking Evans/Potter.

The kid who walked around in hoodies, smirked like he knew all your secrets, and carried his toddler daughter around like it was the most natural thing in the world.

The kid who, apparently, had the political influence to rewrite international law.

That had sent Tony and Rhodey straight to Harry, who was lounging in the tower with a book in one hand and Delphine curled against him, babbling happily.

Teddy was on the floor, playing with Peter, both of them too engrossed in their game to notice the sudden shift in atmosphere.

It was a picture of peace. Normalcy.

Rhodey shattered it in an instant.

"Lord. Peverell."

Harry froze.

Rhodey had always known there was more to Harry Evans than what met the eye.

The kid was sharp, calculating in a way that reminded him of Tony, but with an edge that hinted at something more experienced. He moved like a soldier, spoke like a diplomat when he wanted to, and had a paranoia that made even Rhodey’s military-trained instincts look relaxed.

But This was a whole different level.

Rhodey wasn’t angry, not exactly—Harry had done this before they even met—but the sheer magnitude of it was impossible to ignore.

Tony was still muttering under his breath, clearly trying to process. "The kid basically rewrote the Accords. He made sure enhanced people weren’t treated like weapons. He—he got Ross arrested."

Rhodey exhaled. "And he never said a damn word."

Harry froze.

Then, very deliberately, he closed his book and looked up. "Ah," he said slowly.

"You found out."

Tony ran a hand down his face. "How?*"

Harry shrugged. "Titles. Old money. Connections people don’t talk about. Peverell is a name that opens doors. And when doors didn’t open? I made sure certain people saw why they should."

Rhodey exhaled. "So you just… fixed it?"

Harry knew what he was asking about.

The Accords.

"I made it fair," Harry corrected.

"The original Accords stripped away autonomy, forced people to comply or become criminals. That’s not accountability. That’s control. So I did what I could. I made sure they felt the consequences of ignoring better options."

 "What does that mean?"

"It means," Harry said with a pointed look, "that certain people in power suddenly found themselves in positions where saying ‘no’ wasn’t a viable option anymore."

(Well it would have been impossible without the help of goblins but they were happy to help create a blood bath even if there was no blood.

And he had money. The goblins were very satisfied.)

Tony stared at him. 

"I knew who you were. And I knew, if things went wrong, they’d use you. Or worse, your people. I wasn’t going to let that happen."

"I did it because it needed to be done. And because I refuse to let something like that hang over my family."

Tony’s breath hitched.

Rhodey suddenly realized—this was about more than politics. More than hero work.

This was about them.

Rhodey wasn’t sure what to say.

The kid had changed the world before they ever entered his life, and yet, everything he did had still been for them.

Harry had rewritten international law not just for superheroes, but to protect his own.

To protect Tony. 

Tony exhaled slowly, running a hand down his face. "Damn it, kid."

Harry smirked, but there was warmth in his expression.

Rhodey just shook his head. "This family is insane."

Delphine stirred,"Da," she mumbled.

Harry kissed her forehead. "Yeah."

Rhodey sighed. "Unbelievable."


Tony Stark prided himself on being able to handle just about anything—aliens, near-death experiences—but nothing could have prepared him for breakfast with family.

He and Rhodey had barely made it into the kitchen before they were met with pure chaos.

Teddy was perched on the kitchen counter, animatedly waving his arms as he told Peter a story.

Pepper was attempting to get Delphine into her high chair—and losing the battle—while Harry stood at the stove, casually flipping pancakes like he didn’t have two tiny agents of destruction under his command.

"I’m just saying," Teddy was saying, "Uncle Ron swears daddy once sleepwalked his way into the middle of a battle and still won."

Peter, wide-eyed, turned to Harry. "That’s not real."

"It’s exaggerated," Harry corrected, sighing. "One time. One time I was sleep-deprived, and it happened to be in the middle of a fight between two schoolmates."

"And you won," Teddy pointed out smugly.

"It was luck."

Rhodey raised an eyebrow. "Harry, That wasn’t luck. Probably.Not after what we learnt about you."

"Debatable," Harry muttered, flipping another pancake.

Meanwhile, Delphine, the tiny menace, was actively resisting captivity.

"No!" she protested, gripping the edge of the chair with surprising strength as Pepper tried to settle her in.

"Delphi, sit down," Harry said without even looking.

"No!"

"Sit down, or no extra syrup."

Delphine gasped in betrayal. "Dada!"

"You heard him, munchkin," Pepper said, finally succeeding in buckling the tiny terrorist into place.

"You gotta listen."

Delphine pouted dramatically, crossing her arms like she was plotting her revenge.

"This is incredible," Rhodey muttered, leaning against the counter.

"Harry’s an international diplomat, basically untouchable, and yet he’s getting bullied by a two-year-old."

"Welcome to my life," Harry said dryly.

Tony took a sip of his coffee before focusing on Teddy. "Alright, kid, tell me more about this sleepwalking battle."

Teddy grinned. "Oh! Well, there was also the time Uncle Ron said daddy accidentally challenged a guy to a duel without realizing it and uncle Neville was trying to prevent daddy from being woken up so he went to fight instead—"

"Teddy," Harry groaned. "We’re not telling them that one."

Peter perked up. "You challenged someone to a duel by accident?"

"Technically, yes. But it wasn’t my fault."

"How is it not your fault?" Tony asked, grinning.

"I was being polite!" Harry protested. "I didn’t know the guy took ‘anytime, anywhere’ literally!"

(Ron: That wasn't being polite, that was goading him to fight.

Hermione and Molly: *disapproval noises*)

Rhodey was outright laughing now. "Oh, I like this one."

Meanwhile, Delphine saw an opportunity.

While everyone was focused on Teddy’s story, she very quietly reached out and stole Tony’s pancake.

Tony blinked as his plate suddenly became empty.

"Excuse me, young lady."

Delphine, pancake in hand, stared him down with her big green eyes.

"Delphi, no stealing food,*" Harry sighed.

Delphine, still holding the pancake, shoved a bite into her mouth. "Mine now."

Pepper hid a smile behind her coffee mug. "Oh, she’s definitely yours, Tony."

Harry smirked. 

Rhodey chuckled, shaking his head. "This is way better than dealing with government meetings."

And for once, Tony had to agree—chaos and all, this was the best way to start a morning.


     A few weeks later 

Teddy had a gleam in his eyes that Peter was starting to recognize as dangerous—not in the ‘life-threatening’ way, but in the ‘this is going to get me in trouble’ way.

"Okay, Petey," Teddy whispered conspiratorially, "I need your help."

Peter glanced at the nearly four-year-old with wary amusement. "With what?"

"Pranking Grandpa Tony and Uncle Rhodey," Teddy said with far too much excitement.

Peter hesitated.

He knew this was a bad idea. Harry had explicitly told him to keep an eye on Teddy, not enable him.

But on the other hand... it was just a harmless prank.

"Okay," Peter relented, "but nothing too crazy."

Teddy grinned. "Of course not!"

That was a lie.


The first prank was simple—switching Tony’s coffee with decaf.

A classic.

A safe choice.

The second was... less safe.

Peter really should have asked more questions when Teddy grinned and handed him what looked like harmless, colorless powder.

"It’s just a tiny bit of food dye, uncle George and uncle Fred gave it to me." Teddy had promised.

Except, one hour later, Tony’s face was a vibrant shade of purple.

Rhodey was bright green.

Neither of them had any idea why.

(They didn't panic.

The reason was simple.

Teddy told them some of Harry's, his uncles Fred and George's mischief.)

Tony squinted at his reflection in the nearest Stark-tech display.

"Alright, which one of you little gremlins did this and How?"

Peter and Teddy both pointed at each other.

Rhodey groaned. "You two are lucky I don’t have time to deal with meetings today."

"Yeah, otherwise our image would be ruined!" Tony grumbled, rubbing his face as if that would somehow make the color disappear.

It did not.

Teddy barely contained his giggles.

"You look so cool like that, Grandpa Tony!"

Rhodey shot a flat look at Peter.

"You. You’re supposed to be the responsible one."

Peter coughed. "Define responsible."

Before Rhodey could respond, Delphine escaped.

Again.


The first time, they thought maybe she had just climbed out of her playpen by accident.

The second time, Tony narrowed his eyes.

The third time, Pepper just calmly sipped her coffee and said, "She probably gets that from you."

Tony scowled. "I don’t know what you’re talking about."

Rhodey looked between Tony and the toddler who had somehow bypassed a top-tier Stark Industries baby enclosure and was now halfway up a counter.

He sighed. "Oh no. There’s two of them."

Delphine clapped her hands as if she’d won a great battle. "Up!" she cheered.

Tony pinched the bridge of his nose. "Yeah, okay, I see why Harry is constantly paranoid now."

Just as he said that, Delphine reached for a Stark-tech prototype sitting on the counter.

Tony lunged.

Rhodey lunged.

Pepper didn’t lunge. She just took another sip of coffee as Tony and Rhodey barely managed to grab the highly volatile, expensive piece of tech.

Peter, still guilty about the prank, scooped Delphine up.

"Okay, kiddo, maybe let’s not destroy Grandpa Tony’s stuff today."

Delphine pouted. "Fun!"

Tony was so close to losing it. "No. Not fun."

By the time Harry returned, Tony was exhausted, Rhodey looked like he was ready to retire, and Peter was questioning his life choices.

Pepper was completely unbothered but keeping an eye.

Harry raised a brow at the scene before him. 

Pepper smiled. "Your daughter is an escape artist."

Harry snorted. "Yeah. I know."

Teddy ran up to Harry and latched onto his leg.

"It was so much fun! Peter helped me prank Grandpa Tony!"

Harry slowly turned to Peter, who froze like a deer in headlights.

"You—" Harry exhaled. "You let Teddy rope you into pranking Tony?"

Peter raised a finger. "Technically, it was harmless."

Tony, still purple, crossed his arms. "Yeah. Harmless."

Harry tried. He really tried to keep a straight face. But when Delphine reached up to pat Tony’s cheek, he lost it.

He laughed.

It was warm, genuine, and fond.

Tony froze.

Rhodey blinked.

Peter just grinned.

"Me- Man, you guys look like a mess," Harry said between chuckles.

He carefully took Delphine from Peter and kissed the top of her head. "You had fun today, huh, little menace?"

Delphine gave him a toothy smile. "Fun!"

Teddy beamed. "I had fun too!"

Tony groaned. "Yeah, kid. We know."

Rhodey rubbed his temples. "This was one day. How do you do this every day?"

Pepper smirked at them. "New respect for Harry?"

Tony sighed. "Yeah, yeah. We get it. The kid’s some kind of parenting wizard."

Harry just smiled.

(Tony: Parenting is hard.

Harry: *side eye*.

Tony: you must be a wizard.

Harry:*smirks*)


Ned wasn’t the type to get paranoid.

That was usually Peter’s thing.

But lately, something felt off about Harry.

It started one day, after Harry came back from work and suddenly decided to pick them up—which wasn't unusual but he started picking them up from school every day— Not that they have complaints about it. Infact both of them were pretty happy.

It wasn’t anything obvious at first—just little things.

A shift in his posture—a battle ready stance according to Peter who learnt from Harry to identify the necessary tics during a fight, the way his fingers twitched when someone walked too close.

And then there was the fact that Harry had started disappearing more frequently.

At first, Ned thought it was just work.

Harry was a consultant for law enforcement, after all.

But the problem was, Harry was way too good at keeping secrets.

Ned had seen him lie smoothly to Tony Stark’s face before, and Mr.Stark was, like, a human lie detector.

So if Harry was acting suspicious, then something was definitely going on.

And Ned hated not knowing what.

So, when Harry slipped out of the house at nearly midnight—Ned and Peter were crashing at Harry's for the night—Ned made a choice.

A stupid, reckless choice. But hey, wasn’t that basically the Parker-leeds-Evans/Potter/Stark family motto at this point?

He followed him.


Harry was playing a dangerous game.

Antonin Dolohov was a name that should have stayed buried in the ruins of the war.

But like all bad things, he had crawled his way back into the world, leaving bodies in his wake.

MACUSA had reached out, their message clear: Dolohov is here. We need you. He might target you or those close to you. Be careful.

Harry hadn’t hesitated.

This wasn’t about politics, or power, or duty.

This was personal.

Dolohov was a monster—one of Voldemort’s most ruthless killers.

If he was loose, Harry wasn’t going to let anyone else clean up his mess.

Not if Antoni Dolohov was after him

Not if his family might get hurt.

That was how he found himself tracking a trail of dark magic through the streets of New York.

His proximity wards detected malicious magic in Queens.

His wand hidden but ready.

He moved in silence, a predator stalking prey.

What he didn’t expect was Ned Leeds stumbling into the alley behind him.

Harry whirled, wand raised before he could stop himself. The second he recognized Ned’s face, he cursed under his breath.

"What the hell are you doing here?" Harry hissed.

Ned, for his part, looked both terrified and very determined.

"Following you. Because you’ve been acting shady as hell more than usual, and Peter and I aren’t dumb and both of us as are worried, okay?" He folded his arms.

"Also, I might have used Peter’s tracker tech, but that’s not important right now."

Harry exhaled sharply. He didn’t have time for this.

"Ned, you need to go home."

"Not happening," Ned shot back. "Not until you tell me what’s going on."

A sharp crack echoed through the alley. Apparition.

Close.

Too close.

Harry’s eyes snapped to the street corner just as a shadow detached itself from the darkness.

A voice, laced with cruel amusement, slithered through the air.

"Well, well. The Boy Who Lived. How nostalgic."

Dolohov.

Harry moved before Ned could even breathe, shoving him back against the wall just as a jet of green light seared through the air where Ned had been standing.

"Go!" Harry barked, stepping forward, wand blazing with magic.

Ned’s eyes were wide with terror. But then something strange happened.

As Dolohov raised his wand again, a nearby trash can launched itself through the air—directly at Dolohov’s head.

The unexpected force sent the Death Eater staggering back, just long enough for Harry to counter.

Ned, breath coming in short gasps, stared at his own shaking hands.

"What the—what just happened?!" Ned yelped.

Harry didn’t have time to answer.

He filed it away for later.

Right now, he had a fight to finish.

The fight wasn’t easy but wasn't difficult either.

Not after what he went through.

Dolohov had always been a brutal duelist and Harry had to fight smart afterall he cannot use much power since he has to fight while protecting Ned while also making sure no muggles get notified or accidentally become collateral damage.

The battle raged through the alleyways, spells colliding in bursts of deadly light.

Harry knew he couldn’t let this fight go on.

Not in the middle of a city filled with Muggles.

So he did what he did best. He ended it.

An opening.A flick of his wrist. A whispered incantation. And Dolohov fell, bound in unbreakable magical chains, his unconscious form collapsing onto the pavement.

MACUSA’s Aurors arrived moments later, taking Dolohov into custody. Harry barely gave them more than a nod before turning to Ned, who was still standing in shock.

"We’ll talk about it later, I promise." Harry told him, voice firm but not unkind.

Ned nodded dumbly. "Yeah. Okay. Cool. I just—okay."

By the time Harry and Ned made it back home, exhaustion was setting in.

(Mostly mental exhaustion rather than physical)

He stepped through the door, ready to scoop up his kids and pretend the night had been uneventful.

He didn’t get the chance.

May—who Peter called when Teddy woke up with no Harry and Ned—took one look at him and frowned. "You look like you fought a hurricane."

Peter, sitting cross-legged on the couch, immediately went on high alert. "what? What happened?"

Teddy,—who had woken up —however, was not concerned at all. He gasped dramatically. "Cool! Battle mode!"

Harry sighed. So much for hiding it.

May crossed her arms. "Sit."

Harry huffed but obeyed. As May fussed over his rumpled clothes and smoothed out his windswept hair, Peter studied him carefully.

"What happened?" Peter asked. 

Harry met his gaze, considering. Then, he sighed.

"Just… unfinished business," he said. "But it’s finished now."

May just hummed. "Unfinished work? Really?"

Harry chuckled. "Yes, ma’am."

Teddy grinned up at him. "Did you fight a bad guy?"

Harry ruffled his hair. "Something like that, cub."

Peter didn’t look convinced.

Ned, sitting in the corner, definitely wasn’t and looked like he was bursting from questions.

Ah.well. He needs to talk to Ned. And perhaps take him to grignots for an inheritance test.
