Chapter Summary: In which Harry Potter was born with two souls and eventually becomes Arthur Curry's boyfriend. (Harry/Arthur Curry, DC Cinematic Universe)

AN: This drabble is kind of a crossover between HP, Pokemon and the DC Cinematic Universe though you don't need to know a thing about Pokemon to understand this.

"I don't want to die. There's shit I want to do. I just want to be fucked by my boyfriend one more time before I die, you know?" Arthur continued, shrugging and gesturing to Harry.

Barry stared at Arthur, his cheeks pinking up. "Uhhh…"

Diana grinned as she looked at her teammates, watching as Arthur spoke.

"I just feel like I never really embraced the land or sea."

"You've embraced me loads of times," Harry remarked, grinning bemusedly.

"Yeah. We're young, you know? You just appeared in my life last year and stayed. Like that parasite fish."

"Hey! Wait a minute," Harry retorted, his eyes widening. "I don't know if I should be offended or not."

Barry looked between the two guys and looked to Diana, who was grinning. Bruce looked like he had no idea what was going on other than maybe they shouldn't be hearing this kind of private conversation.

"I just mean… My point is you stayed. And besides my dad, everyone else has left. There's so much more we can do. Been a loner my whole life before you, before this. Being a part of something bigger like this… Maybe I'm scared because I'm meant to…"

Arthur stopped as he watched Bruce gesture to his feet and raised an eyebrow as he looked down at his own feet. His eyes widened as he saw the glow of Diana's lasso and ripped it off his ankle, huffing out a sigh at the sight. He brought it up to eye level, watched as it continued to glow and then threw it back to her.

Harry's lips twitched up into a smile even as he elbowed Arthur.

Arthur glared at Diana, who shrugged.

"I thought that was beautiful," Diana offered, her grin widening.

Arthur sighed and turned to go, sparing a glance to Harry, his bright green, fond, eyes.

"Hey, if I'm supposed to be this… guardian of the seas… it really does kind of mean looking after you too," Harry remarked, lifting his shoulders in a slight shrug, his smile wide. "But you know… the sex does help."

Arthur elbowed Harry back, muttering under his breath about wizards and fucking guardian of the sea bullshit.

"I totally wouldn't have said anything without the lasso, you know."

"Right… Just keep telling yourself that.."

Arthur sighed and walked to the back of the jet plane, stopping in front of Barry. The younger man looked at him with wide eyes.

"Say anything and you'll meet every piranha I know," Arthur muttered, before walking off.

Barry paled and turned to look at Harry, watched as the man rolled his eyes.

"I don't know any piranha, Barry. I don't know if even he knows more than like... three. Those are creepy fish, you know."

Barry yelped, his voice going high pitched as he spoke. "THREE! Three! I don't want to know! I honestly didn't hear anything after 'we're all going to die'!"

Harry snorted and idly walked to the back of the plane to rejoin Arthur.

"No sexy times back there!" Victor called out, his flesh eye narrowed in thought. "We don't have time!"

Silence filled the plane and then they all heard grumbling coming from where Harry and Arthur were.

"On me," Diana whispered and they all heard it, even over the sirens that the Batmobile was sounding. She had a tight grip on her sword, her lasso in her other hand as she dove forward into the mass of bugs.

Harry exchanged looks with Arthur, nodded to him and then jumped up into the air, shifting shape between one minute and the next. He had been born with two souls… one a human soul and the other… His bones shifted and elongated and his arms shifted and his song filled the air as he changed from human to… something else.

The light of the sun hit his thick hide and warmed him up even as the other power within him heated him.

He heard distant gasps from Barry and Victor and then flew off, following Arthur overhead. He flew into an air current, dipping his wings inward right to a group of bugs and opened his mouth, drawing on the hidden power within his other body and shot it right at the parademons. They screamed and exploded on impact and he flew on, shooting forward to catch Arthur as he fell from Victor's hold.

Arthur grinned when he saw him and held on tight to the blue spikes on his back. "You do make for a beautiful parasite fish."

Harry grumbled lowly and bucked him off, flipping his tail up and dropping. Arthur yelped and summoned water with his trident as he fell towards the ground. Water from an underground pipe broke through the cement and raced up to meet Arthur and carried him safely back to the ground.

Once Superman entered the fray, Steppenwolf was doomed. Harry hovered in the air as they all watched as their opponent was carried back up to his ship or whatever it was, beating his wings smoothly.

"You look like a dragon but not like a dragon…" Barry trailed off as Harry blinked a golden eye at him, the other soul within him humming with power.

"I am a guardian of the seas, young one. I am young and old at the same time, as I share this body with the wizard Harry Potter."

Barry froze as he looked up at the creature that floated above them, watched as it stayed in the air gracefully. There were no panicked movements to the animal or creature, no unneeded action that kept it in the air. The creature was all white, with blue spikes on its back and amber eyes that looked very intelligent. "Did you guys just hear that?"

"That's my boyfriend," Arthur remarked, his smile wide and his eyes bright.

"Uh… yeah… I figured that. How… What is he?"

"I was called Lugia in a different life."

Barry blinked and watched as the creature slowly lowered to the ground and shrunk, slowly reforming back to two legs. Harry reappeared after a minute, breathing a little heavily but appearing fine. His skin had a slight glow to it as if something was lit up inside him, perhaps the same kind of power that they all saw him shoot at the parademons.

"We share a body," Harry offered, shrugging and walking over to Arthur's side. "Lugia and I. It's a little complicated but I'm both a wizard and… kind of like a demigod? I don't know… Lugia was rather legendary in its world and in dying… It found me for a new body."

"Sounds creepy," Barry said, his eyes widening at the explanation.

Harry shook his head, flicking to Arthur before looking back at him. "No. It wasn't… We were born together. I'm used to it."

"And then there was the whole Voldemort thing too. That kind of… put a damper on it." Arthur watched as Clark turned towards them, the man obviously listening in.

"Voldemort?" Victor echoed.

"Yeah. I'm a wizard… in addition to this," Harry said, gesturing to himself. "That was a whole other can of worms. Lugia didn't much like having a third soul attached to our body."

As soon as they got home, Arthur tugged him aside to their bedroom and Harry grinned, watching as Arthur stripped his shirt off. Harry followed suit and shucked off his shirt, glad that he had mastered the spell that kept his clothes dry in the water when he swam, and leaned into Arthur, pressing his lips to the man's.

Arthur groaned at the touch and Harry curled an arm around his shoulders to draw him in closer, threading his fingers through Arthur's hair.

"You know… you really are beautiful in your other skin," Arthur remarked as Harry pushed him up against the closest wall. Harry trailed kisses down his chin and throat and Arthur moaned, his cock hardening and his heart racing at the warm touch. "I don't deserve you."

"Arthur…"

"I'm a half blood."

"I'm a half blood too. Lily was a muggle born and James was a pureblood. I don't care," Harry retorted, sucking a kiss onto the base of Arthur's throat. He grinned as the man whined, bucking into him. "Atlantis and the wizarding world can fuck off."

"Who said anything about Atlantis? I don't give a shit about it," Arthur muttered, curling his arms around Harry's shoulders to try for more friction.

Harry grinned, raising an eyebrow. "Who did you encounter when you went to go get the mother box from Atlantis?"

"A woman and some guards. Steppenwolf wiped most of the guards out except for the woman before I got there," Arthur replied, his eyes widening in arousal as Harry reached in to rub circles into his skin, moving up and trailing his tongue over his skin. Harry groaned as Arthur yanked him up and into a kiss, wet and hot, heat building in his body. Sparks of pleasure fluttered throughout him even as Harry slipped a leg between his thighs for friction and their cocks touched, sending shudders through them both. "Course she seemed a little pissed off that I was there. Said something about responsibility."

"Her loss," Harry whispered, nipping a kiss into Arthur's skin, right on the crook of his neck.

Arthur whined even as Harry rolled his hips. They both let out a gasp and Arthur moaned, feeling Harry lave his skin, before reaching down a hand. His cock nearly ached with the need to be touched, the battle having sent adrenaline coursing through him. "Harry."

He shuddered as he felt Harry's warm fingers trail over his skin, nails leaving goosebumps in their wake, and slipped down under his waistband. Arthur bucked into Harry's hand, his heart racing and sweat dribbling down his back.

"It was hot watching you pin Bruce to that wall, I've gotta say," Harry muttered, pressing his mouth to Arthur's.

"Man's human is all I can..." Arthur retorted, shrugging, his voice trailing off on a whine as Harry's fingers finally wrapped around his cock. "Fuck."

He arched into the fingers wrapped around him, leaning into Harry, as the man stroked him. Pleasure spiraled through him as Harry met and caught his eyes, holding his gaze as he twisted his fingers and nipped a biting kiss into his neck, sending his nerves alight with fire. He yelled out as he shuddered with release, pleasure and warmth rocketing through him.

He heard an extended groan even as his eyes fluttered closed, Harry's arms holding him up.

Arthur stared at the oncoming wave even as his dad's eyes widened. The darkness of the night didn't help matters even as the tips of the wavepoints shimmered in the moonlight. He stomped on the gas pedal of their truck and the truck charged ahead, groaning at the new speed. Harry poked his head into the front seat, his eyes glowing silver.

"Who the fuck has this kind of power?" Harry muttered heatedly, his voice hard and yet inhuman sounding too. His voice echoed in the small cab, deep and powerful, a hint of the ancient, legendary creature that Harry shared a body with. "And yes, Lugia's pissed."

"I would be too," Tom whispered, his voice shaky as the giant wave picked up a cruise ship and carried it to the more northern shore. They could even see a Navy battleship on top of the wave several miles south of their location, birds scattering all around them.

"Go!" Harry exclaimed, reaching over to put his hand on Arthur's shoulder.

He did not need to the encouragement even as the truck sputtered and charged on but even that… The wave was faster and collided with the truck even as Harry's hand withdrew and a glow filled the cab of the truck. Arthur heard Harry jump out through the back window, breaking glass as he did, and instantly change, Lugia's soul coming to the fore.

The glow that surrounded Lugia lit up the road and wave, the guardian of the seas hovering protectively above them and opened his mouth. A creature with a 55 foot wingspan. Arthur remembered seeing Harry and Lugia change for the first time, remembered being awestruck. Song filled the air, echoing off the hills behind them and this section of the wave froze in the air, held in check by Lugia and Harry's sheer force of will.

Arthur stopped the car slowly, put it in park and got out to watch.

Lugia sang louder and beat his wings idly, flew forwards a little and the wave moved. Arthur watched in awe, his heart racing within his chest, hearing his dad's mouth open and close. The woman who he had seen earlier yesterday jumped through the water even as this section of the wave collapsed back into the water.

The Atlantean woman stared right up at Lugia and Harry, her blue eyes wide and her red hair wild.

When the danger passed, Lugia and Harry turned around in the air, his silver eyes on the other parts of the coast that weren't so lucky. Disaster sirens filled air to the north and south and Arthur could smell the overwhelming scent of salt water in places where it shouldn't be.

"Who did this?" Arthur yelled over, facing the woman who was still watching his boyfriend.

"This is Orm's doing," the woman replied, raising her voice as Lugia and Harry wheeled about and came back to land, slowly, gently falling to earth.

Arthur grimaced at hearing her words, remembering Vulko telling him of how his mother had born a second son to King Orvax. He watched as his boyfriend came to land on the ground, Changing back slowly in comparison to other times. Perhaps it was the stress that he had Changed under.

"You alright?" Arthur asked, raising an eyebrow.

Harry stood in front of him, his eyes still glowing silver, but dipped his head in a nod. "Orm's doing, huh?"

"Yes. I need your help to stop him, Arthur."

Arthur blinked at her and looked at Harry, who shrugged.

It's your call, Arthur. The seas are rough and that took a lot of energy out of me.

"What's your name?" Arthur questioned, peering at the woman again. "I never asked."

"I'm Princess Y'Mera Xebella Challa but you can call me Mera. Who is your friend?"

"I'm Harry. Just Harry."

Mera looked at him, her eyes narrowed.

"I'm Arthur's boyfriend," Harry added, gesturing to Arthur.

"You are not human."

"Uh… Yeah, I am. Last I checked."

"You're a wizard."

"Yep. I should probably check on my friends though. That wave… it happened all over the world."

Mera stared at him, blinking once then twice. "I… am confused."

Harry's lips twitched up into a smile and Arthur rolled his eyes.

"Alright. We are stopping this war then," Arthur muttered. "That's it."

Mera nodded, tilting her head to look at Harry as if a different angle would help. Harry blinked and looked at her before nodding to Arthur.

"Sounds good to me."
