Author's Note:

I started writing this story three weeks ago after having read Harry Potter: The Avenger by Kb0. That story is very good, particularly in its portrayal of Natasha Romanov and made me crave more fanfic time with her. I went looking for more fanfics that were Harry/Natasha and found a distinct lack of any good quality fics with that pairing of a sufficient length to sate my appetite. So I wrote my own.

Natasha Romanov/Black Widow is played by Scarlett Johansson

Chapter 1

Midgard, Earth, Over the Atlantic Ocean off the Coast of North America, 2012…

Harry came into being nȧkėd. He had only a moment to contemplate his nȧkėdness and the fact that he was in a new universe before gravity took hold along with the vacuum created by an invisible machine located right below him. He was suċkėd right into the turbine of some kind of high powered giant thruster fan. Harry got stuck in the fan on the way through. If he had still been mortal the fan might have won and cut him to pieces. As of a few minutes ago Harry had ceased to be mortal which is basically how he ended up in this new universe.

Harry was 477 years old. Really, he reflected as he tore through the thruster ȧssembly, in order to understand his current predicament one had to go back much further than the last few hours of his existence. But he didn't exactly have much time for reflection at the moment for he was knocked out of the thruster ȧssembly which promptly let out a small explosion as debris caused it to stop after it had thrown Harry out. Gravity once more took hold and Harry really wished for his broom right about then. He was preparing to try a wandless levitation spell on himself which would make him float really awkwardly when he suddenly realized he knew how his broom worked magically on a level he couldn't have perceived before. And Harry realized he could mimic the magic of his broom so promptly did so and he immediately stopped falling.

"Well this is pretty awesome," Harry told himself.

Harry only had a moment to congratulate himself on his new discovery before the aircraft he had just damaged by accident started falling out of the sky. Aircraft was a misnomer. After Harry activated a spell which allowed him to peer through most forms of cloaking he could see that the flying vessel was actually an old style aircraft carrier with four giant thruster fans. Harry conjured a massive piece of carpet, charmed it physically unbreakable so it could take the weight of that corner of the aircraft carrier without tearing, and then charmed the carpet as a flying carpet. Immediately the aircraft carrier stopped falling. Harry then flew over to the thruster fan and used a repair charm to repair the physical damage. The control circuitry that had been damaged by the explosion would need to be replaced manually. Harry could repair the circuitry too but it would take a more detailed study of the control systems. In Harry's time the energy manipulations of wizards had come a long way.

As Harry had done his work he had noticed several fighter jets had appeared watching him from the top of the carrier, hovering. He noticed their weapons were pointed at him but he gave them no mind. He was trying to do the repair and ȧssimilate all the memories and knowledge he had absorbed from his old universe. Some of that knowledge was in Harry's conscious mind but a lot of it had been thrown into his subconscious. Harry finished the limited repair and flew to what he could tell was the bridge of the craft. Harry vanished a section of the window big enough for him to fly through, went through, and then replaced the window. Guns were immediately pointed at Harry.

"I come in peace," Harry said while holding up his hands.

"Who are you?" A black man with one good eye and an eye patch covering his other eye demanded.

Harry got the sense that this was the man in charge.

Harry used surface legilimency to start getting names and found legilimency was even easier to use than normal except on the man known as Dr. Bruce Banner. Banner had some kind of primal consciousness mixed in with his own similar to werewolves. Eye patch was Colonel Nick Fury who was in charge of the agency known as SHIELD. Harry was onboard a SHELD helicarrier.

"The name is Harry. I just arrived in this universe," Harry admitted.

"You arrived in this universe from where?" Fury demanded, while trying to ignore the admiring looks of most of the women on the bridge. "Why are you here? And would someone get this man a pair of pants."

"I hadn't intended to come to this universe but something very powerful decided to kick me out of my home universe after I became powerful enough to threaten it a few minutes ago," Harry admitted. "And I can provide my own clothing thank you," he added while vanishing the grime from his form and conjuring himself a new outfit.

"What are you?" Fury demanded.

Harry had walked closer to the round briefing table sitting in one corner of the bridge as he spoke. The guns were still trained on him but he ignored the weapons. They no longer threatened him. Instead he walked up to the gorgeous redhead standing next to the table, Natasha Romanov AKA Black Widow, and while taking her hand he kissed the back of it.

"Harry Potter, Wizard, at your service, beautiful," Harry said with his best roguish grin.

"Mr. Potter, release my agent," Fury demanded.

Harry dropped Natasha's hand and turned to face Fury.

"You know you are kind of rude," Harry told Fury.

Steve sensed things were getting tense so stepped up and took Harry's hand in a shaking gesture and said, "Steve Rodgers. It's a pŀėȧsurė to meet you, Harry."

Harry grinned at Steve and replied, "Likewise. I like you Steve. You have manners."

Bruce then stepped forward and took Harry's hand and introduced himself.

"Bruce Banner, Mr. Potter," Bruce greeted.

"Call me Harry," Harry invited.

"I'm a scientist and find the idea that you are from another universe fascinating. I would love to compare the similarities and differences between our universes at some point," Bruce stated.

"Dr. Banner, this is not the time," Fury chastised. "Mr. Potter, what did you do to my helicarrier?"

"Well I didn't really intend to do anything to it. When I materialized in this universe that thruster engine ran into me. I've repaired the physical damage to the thruster ȧssembly itself but I'm afraid the resulting explosion did in some of your control circuitry. So I made a magic carpet to hold that corner of your ship up while you repair your thruster," Harry explained.

"Magic carpet," Fury said skeptically.

"I am a wizard. Magic is sort of implied in the name," Harry pointed out. Steve openly grinned at that response. Harry thought he caught amusement in Natasha's eyes. "You know…if you are going to be so rude I can happily go find somewhere else on this world to amuse myself. I do need to get acquainted with this world. Please tell me you all still have pizza on this Earth?"

"Oh we definitely do," Steve confirmed.

"I'm afraid I can't allow you to leave, Mr. Potter," Fury stated.

All traces of friendliness vanished from Harry's countenance and he fixed Fury with an icy gaze.

"Director Fury," Harry began as the temperature in the bridge noticeably dropped, his tone cold. "I could vaporize you and this entire helicarrier with very little effort and there is nothing you or anyone in this room could do about it. Believe me when I say I can leave any time I want to. I won't vaporize your multibillion dollar toy because I like Steve and Bruce here and feel Natasha there is too beautiful to die in such a way despite the fact she hasn't said a word to me."

There was silence for several moments and then Fury asked in a whisper that carried across the bridge, "How did you know her name?"

"Everyone projects their name quite clearly via their surface thoughts," Harry answered honestly.

"Harry, you seem like just the guy to help us out with a problem we are having," Steve said.

"Oh, do tell," Harry said as he took a seat at the table. "I hope you don't mind but traversing universes really takes it out of a guy and I would like to sit down."

Fury gestured for his men to finally lower their guns. Just from the few tricks Potter had performed Fury wasn't sure the guns would have done any good anyway. The guy had survived falling through one of the helicarrier's thruster turbines.

"We have an angry Asgardian that may or may not be a god wreaking havoc on Earth. He goes by the name of Loki, the Norse God of Mischief and Trickery," Steve explained.

"Oh we had one of those in our universe too. He was a really powerful wizard," Harry mused.

Fury exchanged glances with his second in command Maria Hill. If the wizards in Potter's home universe could pass themselves off as gods then that meant Potter was likely at least in the Asgardian weight class as far as power was concerned.

"Loki stole an object of nearly limitless energy known as the Tesseract after killing a lot of people. We were just about to begin working on tracking the Tesseract when you showed up," Banner stated.

"Agent Coulson, would you show Dr. Banner to his laboratory?" Fury requested.

Fury had been about to ask Natasha to guide Banner to the laboratory which had been prepared for Banner before Potter's arrival. But Romanov seemed to be a calming presence on Potter or at least she exerted some small influence over him. Coulson and Banner left. Fury switched mindsets. He still didn't trust Potter's sudden appearance but it appeared Captain America liked the wizard. Cap's opinion carried a lot of weight with Nick. Besides, it wasn't like Banner was any more trustworthy given the creature he could turn into. It seemed like Rodgers was laying the groundwork for recruiting Potter into the Avengers initiative. It was time Nick got to know Potter a little better so he sat down at the table and began talking with Potter.

Harry had finally seemed to gain a measure of Fury's trust or rather Fury wasn't actively hostile anymore. From what little digging Harry had done in Fury's mind the SHIELD Director didn't trust anybody. Harry had also determined that he was going to have fun here. There were so many interesting things going on.

"Agent Romanov, would you escort Mr. Potter to guest quarters so he can get settled in. It might be a while before we get a hit on Loki or the Tesseract. Mr. Potter, we will let you know when we do so that you can be involved," Fury explained.

Harry nodded and followed the attractive redhead Natasha out of the bridge. As he followed her she was projecting thoughts in his direction, primarily the thought, "Are you reading my mind."

"To answer your question, no I am not reading your surface thoughts. But you are projecting that thought so loudly I can pick up on it without actively trying. Do you have telepaths in your universe?" Harry asked.

"Yes. But they generally don't make a habit of letting us study them so they aren't well understood," Natasha answered.

"I can understand why," Harry said wryly.

"So what powerful being kicked you out of your universe?" Natasha asked, hoping to gain some Intel on the newest possible recruit to the Avengers initiative. Before Harry could answer Natasha's earpiece beeped. She held up a finger at Harry and pointed towards her earpiece. "This is Widow, go ahead." She listened for a moment before saying, "Acknowledged." To Harry she explained, "They have located Loki in Germany. We need to go get ready for a mission. Are you good to go so soon or do you need to recoup?"

"Oh I'm good to go. I worked as an Auror and then a Hit Wizard for a couple of decades each. We had to be ready to go at a moment's notice," Harry explained as he followed Natasha to where he was ȧssuming they were going to gear up.

Natasha didn't know what an Auror was but she could guess what a Hit Wizard was.

"How old are you? You don't look several decades older than the age people generally start working," Natasha mused.

"Why thank you. That is always nice to hear. I am 477 years old," Harry answered, causing Natasha to stop and look at him in amazement.

Natasha composed herself again and continued walking.

"The more I hear about you the more you sound like an Asgardian," Natasha admitted. "Though only Loki has demonstrated some of the abilities you seem to possess and he had to use some kind of scepter to do it. I think the scepter was providing a lot of the power because it had a glowing crystal of some sort in it."

"Hmm…I would like to study these Asgardians. Maybe they have a way to help me gain access to my home universe," Harry mused.

Natasha and Harry reached the room with the gear in it and found Steve gearing up already so they didn't really have much time to talk further.

Stuttgart, Germany…

Natasha piloted the transport ship close enough to the facility Loki was at, the Stuttgart Science Institute (SSI), to get Harry and Steve close enough to reach the facility swiftly but far enough away not to alert Loki to their arrival prematurely. Harry held on to Steve and flew out the back of the transport and silently towards the SSI. They arrived to see multiple Loki's holding a glowing scepter standing around a crowd of people. Only one human, an older German male, was not bowing.

Loki was just saying, "Look to your elder, people. Let him be an example."

Loki said this while aiming his scepter and preparing to kill the German man. Harry dropped Steve at just the right position that Captain America was able to drop down and bring his Vibranium shield in front of the scepter blast. The energy blast reflected right off the shield and straight back into Loki, knocking the Asgardian down.

"The last time I was in Germany I saw another man standing above everybody else," Steve said as Loki got to his feet and Harry touched down off to the side. "I ended up disagreeing with that man."

"The soldier," Loki said with a disdainful tone while looking at Steve. Then he shifted his focus to Harry and Harry immediately felt Loki's magical senses probing out at Harry's being. Harry deflected the probe which immediately drew back. "And who are you?"

"The name is Harry," Harry answered.

Natasha chose that moment to pilot the transport into position and while hovering lowered a nasty looking automatic weapon on a swivel mount out of the belly of the craft.

"Loki, drop the scepter and surrender," Natasha's magnified voice came out of the transport.

Loki responded by firing an energy blast at the transport which Natasha managed to avoid. At the same time Steve threw his shield at Loki before surging forward and punching the Asgardian. Loki responded by two hits with the scepter which Steve managed to block before the third swift blow sent Captain America tumbling. Harry strode forward and caught the scepter as Loki attempted to hit the wizard. Loki tried jerking the scepter out of Harry's grip but to the Asgardian's dismay it didn't work. Loki lashed out with a fist and tried striking the wizard. Harry's normal technique when facing a foe so strong was to augment his own strength with telekinesis, a technique he had long ago mastered. Harry was finding he didn't need to do that anymore. Whatever transformation he had undergone or was undergoing as a result of his transition to an immortal being had made him stronger, a great deal stronger.

Harry deflected the strike with his free hand just enough to avoid it while kneeing the Asgardian in the groin. Loki let out a wheezing cry and in his weakened state he lost his grip on the scepter. Harry twisted the scepter free from Loki's grasp and sent a massive stunning spell out of his hands towards Loki. Unexpectedly the gem of the scepter reacted to the stunning magic and amplified the effect. The stunner smashed into Loki and pressed the Asgardian against the ground as the energy filled his entire form. Loki didn't even twitch. Harry checked Loki's vitals to make sure the Asgardian was still breathing and found that Loki was out cold but still alive.

Steve stood staring quite surprised at what he had just observed.

"Nice job, Harry," Steve complimented as Natasha set the transport down.

"Yeah…I didn't mean to get him so hard but this scepter amplified my magic," Harry said as Natasha approached.

"How long will he be out for?" Natasha asked.

"I'm not sure. I know nothing of his physiology. With that amplified stunner I just sent at him…if he had been human he would have died. I really didn't mean to hit him that hard. But I can construct some restraining cuffs that might hold him magically restrained even if he does wake up," Harry offered.

"Please do," Natasha replied.

"While I'm doing that could one of you locate every person Loki killed at this site?" Harry requested.

"Why?" Steve asked, confused.

"I would rather not say until after I have encountered the first one," Harry replied.

"Sure, I will see what I can do," Steve answered before walking off towards the nearby SSI.

"Do you need any help?" Natasha asked Harry.

"You could make sure nobody bothers me. I need some considerable focus to summon a sizable quantity of dark and negative matter and then forge it into an alloy to restrain Loki," Harry answered.

"Sure," Natasha agreed.

Harry closed his eyes and held his hands out. Immediately darkness surrounded his outstretched hands. The light seemed to fade from the region between his outstretched palms and it grew darker and darker. Eventually something like a dark glow seemed to form in a tiny region of space midway between his palms. A blackness started to flow out of that region and glide to a region to the right of his right hand which was encased in a light blue glowing shield. It looked like Harry was collecting that exotic matter in a containment vessel. Natasha watched fascinated as Harry collected a healthy portion of that material about the size of her torso. Then he started collecting an energy that shifted colors and crackled like lightning in a silvery containment cage. After he had the same quantity of material as the dark material, Harry pushed the two cages together. Natasha watched as the material let off brilliant bursts of light and small explosions formed within the containment cage.

Then the glow faded and a faintly shimmering material that looked like a metal was left in the cage. Harry dropped the cage and gestured towards the alloy, reshaping it telekinetically into a set of manacles. His fingers danced and glowing runes were etched deeply into the alloy in a configuration that Natasha had no hope of understanding. The runes faded to a bȧrėly noticeable glow slightly less bright than the metal. Harry flicked his hand towards the unconscious Asgardian and the manacles flew onto Loki's wrists. All of this had taken more than fifteen minutes and Harry appeared to be a bit taxed. But then his form shimmered and he looked completely refreshed.

"What just happened there?" Natasha asked.

"A little trick I learned to regenerate myself quickly. Well it took the normal time from my perspective. I just manipulated time to speed it up in a small bubble around me," Harry answered.

Before Natasha could comment Steve came running up.

"Harry, I have located all the bodies," Steve said solemnly. "There are thirteen dead. The local police have the bodies all gathered together now."

Harry and Natasha followed Steve with Loki floating behind them after a gesture from the wizard. The bodies were lined up with sheets covering them. Two of the deceased were a pair of police officers badly disfigured when Loki had blasted their car with the scepter. Harry knelt down next to the first police officer and laid his hand upon the corpse's forehead. Harry closed his eyes and focused. This was not new to the Master of Death. He had revived the recently deceased in his old universe using the Hallows. But he wasn't sure he would have the same ability here.

Harry need not have worried because he found the revival process even easier here. The damage healed on the corpse within moments and then the man's eyes flew open and he sat up in a gasp. Those watching were shocked. Harry moved onto the other cop and performed the same process. Eleven corpses later and Harry was done. All thirteen people were up and being helped by police and emergency medical personnel who had arrived since the end of the fight. Harry rejoined Steve and Natasha who both regarded him with different expressions. Steve was openly in awe of Harry. Natasha appeared quite thoughtful.

"I have to ask…are you sure you aren't secretly an angel?" Steve questioned when he found his voice.

"I'm pretty sure I'm not. Then again maybe I am and just don't know it," Harry said with a half smile and a shrug. "We should probably get out of here before I am mobbed by people wanting to thank me." Harry had noticed some of the recently revived starting to look his way. "In fact, I think I'll meet you two back at the transport."

Then Harry teleported away and took Loki with him.

"Did you know he could do that?" Steve asked casually.

"To be honest I'm starting to question if there is anything he can't do," Natasha admitted. "I mean he did just raise the dead."

"That he did. I don't think he likes people thanking him," Steve mused as he and Natasha turned and started walking towards their transport.

"Yeah. I got that feeling too," Natasha agreed.

Natasha and Steve found Harry chatting with Tony Stark, AKA Iron-Man. Tony had the helmet of his suit of armor retracted and Harry appeared fascinated by the suit.

"Damn this tech is pretty far ahead of this time period. I didn't expect to see anything this powerful as a personal power supply for at least sixty or seventy years," Harry said as he brought his hand to hover about six inches in front of the arc reactor in Tony's ċhėst.

"What are you doing?" Tony asked before a glowing hologram of his arc reactor was projected in the air in the back of the transport. Then the holographic arc reactor disassembled and showed all of its parts. "I know you said you are a wizard but how are you doing that?"

"Like I said, magic," Harry answered. "Hmm…this is pretty impressive," Natasha heard Harry say as she piloted the transport off the ground before handing the controls over to her copilot and checking to make sure Loki was secure.

She idly listened to the conversation between Steve, Tony, and Harry as the transport headed back towards the helicarrier. But she had to stop paying attention when Director Fury asked for a report. A few minutes later Loki woke up. He looked around in confusion before his gaze focused on Harry. The Asgardian stared at the wizard intently as Harry examined the scepter.

"Why are you helping these lower life-forms? They are beneath you," Loki stated.

Harry let out a sigh before saying, "Loki, the only time a human is beneath me is during certain sėxuȧŀ positions when we shag. And sometimes I'm beneath her."

Steve's face got really red and Tony grinned.

"I like this one," Tony declared.

"Seriously, Loki," Harry continued. "I have killed hundreds of my kind over the course of centuries who thought just like you. They sought to rule over those they considered lesser than them and in the end the only time they ever realized they were wrong was when I terminated their life. Hell, some of them didn't even realize it then."

Just then a sudden lightning storm developed around the transport. Harry sensed the magic in the air.

"Where is this coming from?" Natasha asked.

Loki gained an apprehensive expression.

"Based off of Natasha's briefing on you am I to ȧssume this is your brother?" Harry asked Loki.

Loki simply glared as the aircraft shuddered. Harry sensed another Asgardian had just landed on the back of the transport. Tony returned his helmet in place on his armor and opened the back hatch. Thor landed on the ramp. Tony raised one of his arc gauntlets preparing to fire an energy blast at the blonde Asgardian but Thor simply sent his hammer Moljnir against Tony's ċhėst before pressing Iron-Man to the deck of the transport. Thor picked up Loki before summoning back his hammer and spinning it rapidly in a circle before flying out of the back of the transport with Loki.

"You probably could have stopped him," Steve suggested as he helped Tony back up.

"I probably could have. But I've learned it is best not to get in the middle of two siblings fighting. And didn't Natasha tell me that guy was a friendly?" Harry asked.

"Things change. Whatever he does with Loki will lose us the Tesseract," Tony suggested with a growl before launching himself out of the back of the transport.

"Shall we go make sure they don't kill each other," Harry suggested while offering his hand to Steve.

Steve took the hand and was pulled out of the transport by the wizard. They flew after the other three males. Steve had trouble seeing through the storm but Harry didn't seem to even be slowed. He flew unerringly down at an angle. They arrived at ground level to see Thor and Iron-Man fighting quite spectacularly. Harry signaled Steve to hold off intervening for a moment. Harry wanted to see how the two opponents faired against each other. Short term Tony was getting in some serious hits but it appeared Thor had started to damage Iron-Man's suit. Harry could tell that the Asgardian had much more stamina and durability than the inventor. He was willing to bet Thor would win.

"We should stop this," Steve urged eventually.

"Alright," Harry agreed. The wizard set them down in the clearing and gestured with his hands. Telekinetic force lashed out and wrapped the two opponents in its embrace. Thor and Iron-Man flew apart. "That's enough," Harry said.

Immediately Tony activated his boot thrusters and Thor sent his hammer at Harry. Harry had to admit that the amount of power he sensed in that hammer had him a bit uneasy so he abandoned his telekinetic hold on the two opponents. Instead, he side-stepped the hammer's path before reaching out and trying something that would either look really cool or end up being very painful. Harry focused all his strength and his power on catching the hammer. The effort ended up making Harry look wickedly cool. He caught the hammer by its handle and grasped it tightly. The hammer tried to pull away but Harry concentrated on suppressing its flight charms. It was still a battle as Thor tried summoning the hammer back.

"It should not be possible," Thor said.

"Tony," Steve barked reprovingly as Tony raised his arc gauntlet to fire at Thor. "What are you doing here, Thor?"

"I am here to thwart Loki's schemes," Thor replied.

"Thor, my name is Harry. That is Steve and that is Tony," Harry said while indicating the two men in question respectively. "I don't believe we should be fighting. I think you will like me once you get to know me. I think we will like you too. Let's just talk things over. I'm going to let your hammer go as a show of good faith," Harry said just as he released the hammer.

Thor caught the hammer and tested the feel of it. The hammer did not appear changed.

"We work with agent Phil Coulson who I think you have met before," Steve spoke up.

"We can talk," Thor said after a few moments of pause.

Natasha brought the transport craft down as Thor retrieved Loki from a cliff overlooking the scene of the recent skirmish. The two Asgardians landed in the back of the transport and took a seat to one side.

"What are you?" Thor asked Harry as the transport took off again.

"I'm a wizard. I'm not from this universe," Harry admitted.

"And he is very powerful," Loki said while eying Harry with interest. "Did the scepter enhance your power?"

"Yes," Harry admitted. "What is that gem? I can feel the power of it," the wizard said while indicating the gem in the scepter.

"It is one of the Infinity Stones, a relic of unknown power that is left from before the creation of this universe. The Tesseract is another such Stone," Thor answered. "What are you doing here in our universe?" Thor questioned. "We have not had a visitor since long into our past before I was born."

"Then you have had visitors," Harry said excitedly. "It was not my intention of coming to this universe. I was hoping maybe your people had a way to let me go back to my home universe."

Thor and Loki exchanged a look.

"If the Asgardians do then we do not know of it," Loki admitted. "But that does not mean it doesn't exist."

"At some point you may get a chance to ask the All-Father, Odin. He may know of a way," Thor admitted. "Where does this transport take us?"

"To the helicarrier," Steve answered. "It's like a big flying ship. It's the current headquarters of SHIELD."

Thor nodded his understanding.

Harry walked with Natasha while escorting Loki to a cylindrical cage with the outer side made out of a transparent polymer that would be quite tough to break through. Fury was in the chamber too. Harry wanted to spend as much time with Natasha as he could. The redhead was projecting enough thoughts for Harry to pick up so that he knew she really didn't mind his company. She had inquired if it was possible to by some means stop projecting her thoughts for telepaths to pick up. Harry had given her an amulet which would accomplish that task. He neglected to mention that it wouldn't work to block her projected thoughts from him. When she inquired if more of these amulets were available for other SHIELD agents Harry had informed Natasha that for now she was the only person he trusted with one.

Harry stood beside Natasha as Fury addressed Loki.

"In case it is unclear, if you try to escape or so much as scratch that glass," Fury said while opening a retracting iris doorway that vented out of the bottom of the helicarrier. The opening created something of a vacuum slowly suċkɨnġ some air through. "You will plummet 30,000 feet down in a steel trap. I know your brother can fly. Can you?" Fury closed the iris. While gesturing at Loki, Fury said, "Ant." Then indicating the iris control console, Fury said, "Boot."

"That was in reference to an exchange Loki and Director Fury had when Loki first arrived on Midgard," Natasha whispered for Harry's benefit.

"I will admit it is an impressive cage but somehow I think you had another in mind when you designed it," Loki answered while alluding to the Hulk.

"That wouldn't hold me for even a moment," Harry mused quietly to Natasha.

"I have realized that," Natasha agreed. "Let's hope Loki isn't as powerful as you. I was tempted to have you leave those manacles on him."

"I think he would have overcome them eventually," Harry replied.

Bruce, Steve, Tony, and Thor were listening and observing the scene from the bridge where the video of the cage room was being fed.

"You must be incredibly desperate, Director Fury. You would call on such lost creatures to defend you," Loki mused.

"You have forced me to become very desperate, Loki. You threaten war upon my people. You enjoy killing and want to wield a force I am told you can't hope to control," Fury rebutted.

"You are just upset that you came so close to using the Tesseract to achieve unlimited power. Are they really buying that you want to create a warm light for all mankind to share?" Loki asked with a sneer while his gaze flickered to Harry. "I wield real power."

"Let me know if real power wants a magazine to read," Fury answered while leaving the cage room.

Harry and Natasha left from a different exit and Harry teleported them to just outside the bridge.

"That could become handy," Natasha mused.

Harry simply threw her a small smile.

"Well he's just a ball of fun, isn't he," Bruce said retorically.

"Thor, any idea what Loki's angle is? His game plan?" Steve queried.

"Loki is backed by an army of creatures called the Chitauri," Thor answered. "They are not of Asgard nor any world you know of. With them behind him he means to take the Earth from your people. I suspect in return he will give them the Tesseract."

"So he wants to build another portal," Bruce surmised. "He needs Erik Selvig to help him."

"What has Erik Selvig to do with Loki?" Thor questioned.

"Loki took Erik Selvig under some kind of mind control spell," Natasha explained. "He also took one of our agents, Clint Barton."

"I don't think we should be focusing on Loki right now. I think we should focus on the reason they need the Iridium they took from SSI," Bruce suggested.

"The iridium is a stabilizing agent to keep the portal from collapsing in on itself like it did at SHIELD," Tony answered.

Before Tony's personality could go off on a tangent however amusing it would be Harry spoke up and pointed out, "Loki would still need a power source of high energy density."

"Yes, to kick-start the cube," Tony agreed while referring to the Tesseract and slipping a small device on one of the consoles underneath to begin hacking the systems onboard the helicarrier.

"When did you become an expert in thermonuclear astrophysics?" Agent Hill questioned.

"Last night," Tony answered. "I read the packet with Selvig's notes and extraction theory papers. Am I the only one who did the reading?"

"Not the only one," Harry answered. "I found them to be quite basic."

"Yes, well as a time traveler from hundreds of the years into the future I would expect you would," Tony mused. "We really must talk extensively about that."

"Can you be more specific about what kind of power source Loki needs?" Steve questioned, getting the discussion back on topic from Stark's attempt at derailment.

"Loki will need to heat the cube to 120 million Kelvin just to break through the Coulomb barrier," Bruce answered.

"He wouldn't need to do that if he could stabilize the quantum tunnelling effect," Tony pointed out.

"Allowing him to achieve heavy ion fusion at any reactor on the planet. It's possible. I could do it with my technology. Given that Loki has access to technology and science far in advance of Earth I wouldn't be surprised if he could do it too," Harry mused.

"Two men in the same room who speak English," Tony mused. "Dr. Banner, I must also say your work in antielectron collisions is superb. And I'm also a huge fan of the way you lose control and turn into an enormous green rage-monster."

"Thanks," Bruce said.

"Dr. Banner is only here to track the Tesseract. Do you think you would be willing to work with him, Mr. Stark?" Fury asked.

"Let's play, Doctor," Tony suggested to Bruce.

"Don't you want to join them? You seem like you would be an ȧsset in tracking the Tesseract," Natasha suggested.

"Maybe. But I would prefer to watch you work," Harry flirted.

Natasha smiled and appeared thoughtful for a moment.

"Alright…then let's see how good you are hand to hand without using your powers," Natasha suggested.

"You're on," Harry agreed.

HP – HP – Deathly Avenger – HP – Deathly Avenger – HP – Deathly Avenger – HP – HP

Natasha and Harry faced each other. Natasha wouldn't underestimate her opponent. When neither of them acted for several moments Natasha decided to be the one to initiate the fight. She leapt forward while attempting to deliver a side-kick to the side of his head. Harry knocked Natasha's leg to the side and while she was still moving forward he did a back-kick to her buŧŧ which sent her into the wall she was heading towards. Natasha didn't stop moving but instead flipped off the wall and came at Harry again.

Natasha tried a back-fist reverse punch this time followed by a series of kicks from different directions. When Harry countered her moves with textbook precision she continued trying to press her attack but with no luck. The two combatants were a flurry of blows, kicks, and deflections. While Harry wasn't using any above-human strength or speed he couldn't help but utilize his above-human endurance. He never slowed down or tired. Additionally his mind worked at much faster than human speeds. He saw Natasha's movements coming as if she was moving through molasses and thought up counters which he enacted successfully while Natasha was relying on muscle memory. Natasha began tiring and Harry went on the offensive. After the first time Natasha got pinned the tone for the rest of the sparring session was set.

"Now this is just embarassing," Natasha admitted after she was pinned for the fourth time with Harry on top of her.

Natasha was on her stomach with Harry's right arm wrapped lightly around her throat. He could put her out with the sleeper hold but there was no need.

"I've had a lot of time to learn," Harry ȧssured. "Plus I'm not even tired."

"Hmm…I'll just have to employ all my weapons," Natasha said suggestively as she wiggled her hɨps and pushed her buŧŧ up against Harry's groin.

The wizard ġrȯȧnėd and tried moving his hɨps back and up to get his growing manhood away from her delictable derriere. Natasha followed the movement until she had enough space to twist her body starting with her hɨps so that she was now on her back.

"That was sneaky," Harry said with a small smile while bracing himself on his arms.

"I know…but I like this position so much better. Don't you?" Natasha queried.

Harry subconsciously had his magic make the observers in the observation area of the gym realize they had better things to do.

"Yes, but this position makes me even more tempted to kiss you," Harry admitted as he lowered his head a few inches. "I have been so tempted ever since I saw you."

"What is stopping you?" Natasha asked curiously.

Natasha didn't think the super-powerful wizard did anything other than what he most dėsɨrėd to do.

"Worry that you aren't attracted to me," Harry admitted.

"I don't think that is a valid concern," Natasha whispered before closing the distance and kissing Harry.

The rest of the sparring session was a lot more physical and involved a lot of close contact grappling. Harry's wins were also rewarded with kisses. There were a lot of kisses exchanged.

"What did you need, Harry?" Tony asked as he entered Harry's quarters.

Tony drew up short at what he was seeing. Harry had asked Tony to come to the wizard's quarters using of all things a text message. Tony hadn't given Harry a phone number but Tony supposed the wizard from hundreds of years into an alternate universe's future would have plenty of tech tricks to play. What Tony was observing was a region of space in the wizard's quarters far bigger than should have been possible. The room was oppulent and tastefully decorated. Harry stood off to one corner of the room in front of a glowing blue table.

"Tony, I called you here because I wanted to help you with the problem you have with that shrapnel trying to go into your heart," Harry explained.

This declaration actually distracted Tony from the incredible region of obviously distorted spacetime.

"You can help with that? Of course you can. There isn't anything you can't do," Tony muttered to himself as he walked closer to Harry.

"Yes. Please lie down on this medical bed," Harry requested.

Tony eyed the bed dubiously but climbed onto the bed and laid back. Harry touched something on the side of the bed and a hologram of Tony's form appeared over Tony. Only the hologram wasn't of Tony's exterior but showed Tony's insides and the shrapnel was clearly shown as red matter near Tony's heart. Harry's fingers danced and the shrapnel glowed brighter. His fingers shifted over a rapid sequence of glowing figures Tony couldn't follow and then the shrapnel was gone. Harry next highlighted the arc reactor in Tony's ċhėst and the hole in Tony's ċhėst surrounding the reactor. A moment later the reactor was floating above Tony's ċhėst and there was no longer a hole in his ċhėst. Tony gasped and reached down to feel his unblemished skin where the hole had been. He stared up at Harry in amazement.

"Was that more of your magic?" Tony asked.

"This device is a blend of magic and technology. There are non-magical devices which can do something similar but they are a lot bulkier," Harry explained.

"Do you know how to build them?" Tony asked as he sat up and plucked the arc reactor out of the air. "I'm ȧssuming this bed can do more than what it just did for me."

"This bed is capable of healing any illness, ailment, or injury known to the people of your time," Harry admitted. "Yes, I can build the technology versions. When I was kicked out of my home universe it was because I got a major upgrade in my abilities. One of those abilities is that I can interface with any object in a non-corporeal form and know intimately how it works down to the atomic scale. I interfaced with everything in my home which included my personal computer and the internet it was connected to. In my time the internet had evolved to a scale you can't imagine even though you are a genius. I was connected briefly with every networked system on Earth and throughout the other star systems the Earth network was connected to via the subspace network. All that information is buried mostly in the subconscious part of my mind. I can dig it out if I look hard enough."

"Amazing," Tony declared. "Would you be willing to license the healing bed technology to my company? I want to make this available to help everybody. I will pay you fantastic royalties."

Harry was thoughtful for a few moments.

"We can do that," Harry agreed. "But we're going to have to install some protections in your manufacturing facilities, protections from my side of the supernatural street. I don't want this technology reproduced out of our control. This technology can scan and manipulate bio-matter down to the atomic scale. Before restrictions were put in place this same tech was used to create enhanced biological organisms that would give Thor and the Hulk a run for their money in strength and speed."

Tony shuddered at the idea before he looked down at his arc reactor.

"This could cause problems with my suit," Tony said. "Not that I'm not grateful. Because I am. You have no idea how much."

Harry summoned a blue metallic looking ring with an inside diameter matching the outside diameter of the arc reactor. The ring was quite thin and not too wide beyond the inside diameter. It had runes carved into the surface so tiny Tony really couldn't make them out. Harry took the arc reactor from Harry and pushed it base first through the opening of the ring. Tony watched in fascination as the arc reactor disappeared into the ring. Harry then placed the ring against Tony's ċhėst and the ring stayed there.

"That ring is now keyed to you. You merely have to think that you want the ring and no matter where it is the ring will come to you. Only you and I can remove the arc reactor from the expanded pocket space within the ring. "You can also fit a couple more arc reactors as spares beneath that ring," Harry explained.

"You are officially wicked cool," Tony declared with a wide grin.

"Yeah…I know I'm pretty bad-ass," Harry ȧssured with a matching grin.

"Thanks, Harry," Tony said sincerely.

"No problem," Harry ȧssured as Tony hopped to his feet and put his shirt back on.

"So I heard you and Natasha put on a show when you sparred in the main gym," Tony said. "I also heard you astounded everyone onboard when you kicked her ȧss in hand to hand."

"I would never kick Natasha's ȧss. It's too nice to bruise. I merely showed her that although she is quite skilled in physical combat, she still has a few tricks to learn," Harry replied diplomatically.

"Uh huh," Tony said. "You've really got it bad for her."

"What can I say. I like gorgeous women," Harry replied.

Tony's humour diminished and he said, "Listen Harry. Bruce and I think something is up with SHIELD. We don't buy into Fury wanting the Tesseract for a clean unlimited energy source. They want it for something else I'm sure. I've got my AI Jarvis hacking into their systems as we speak. In a few hours I will know everything SHIELD has in their systems."

"A prudent course of action," Harry mused. "I'd be interested in knowing what you find."

"I'll keep you informed. You think sometime I could study one of these regions of distorted spacetime?" Tony asked.

"Sure," Harry agreed. "I'm going to go see what trouble I can get up to on this boat. I'll drop by your lab in a while."

Tony nodded and left.
