Chapter 5: The Battle of New York Part 3 – Joining the Fight

As he disappeared from the room, the red-haired girl continued to gaze out of the window, her eyes fixed on the city below. She then glanced up in the direction Harry had disappeared, a faint smile gracing her lips as she whispered softly, "Go get 'em, tiger."

After two apparitions, Harry eventually arrived on the roof of a towering building that afforded him a great vantage point for overlooking the vicinity where the load roar and brieg lightning show had seemed to originate. As he surveyed the landscape below him, a wave of uncertainty washed over him, causing him to come to an abrupt standstill, trying to figure out what he was looking at.

On the elevated street at the base of the building, a peculiar mismatched gathering of six individuals caught his attention. Positioned in a relaxed circle, they seemed engrossed in casual conversation, although judging by what was happening around the city, Harry very much doubted that was the situation. Recognition dawned swiftly for Harry as he immediately identified Clint and Nat, with whom he had crossed paths and fought alongside just a little earlier in the day. Another figure, garbed in the striking red and blue leather, seemed to hold the collective attention of the individuals present as he was talking to them. Harry vividly remembered this person's leap off a bridge as he had approached the archer and the assassin earlier to try and help them.

Off to the side, hovering slightly above the ground, Harry got his best look of the afternoon of the gleaming metallic sheen of the technological marvel, that was "Iron Man". Harry stared for a second, his attention drawn to the smooth lines of the engineered suit, a sleek combination of red and gold metal. Even though he had seen some rather miraculous things in the magical world, he still paused and marveled at the seamless design of the impressive armor.

Almost without meaning to, Harry's gaze skimmed over the next figure before it snapped back in recognition. The poorly fitting clothes and the discarded moped on the ground triggered a memory of his earlier encounter with this individual. Despite his inconspicuous appearance, the man had stood out in Harry's memory, likely for his very relaxed appearance. While all members of the group below him looked confident, that man in particular looked as if he never feared anything. In any other circumstance, the man in ill-fitting attire might have stood out the most, simply for his attitude, but another presence overshadowed him and indeed every other member of the group … the last member of the group. A modern-day Viking towering over his companions, exuding an aura of strength, he wielded an enormous war hammer, which seemed to cackle with energy.

Harry looked down from his vantage point, staring at the collection of individuals assembled beneath him. Noting the absence of fighting and recognizing familiar faces such as Clint, Nat, and Iron Man, he assumed this must be a group of heroes preparing to fight. As Harry was thinking about whether to go down and introduce himself, he suddenly felt the building beneath him tremble. The shaking was accompanied by a low, deep rumble emanating from drown the street.

Turning himself towards the source of the disturbance, Harry was frozen by the sight of a space whale rapidly approaching the assembled heroes, flying at street level. His mind raced through potential strategies to stop the colossal creature, but apprehension set in as he realized that none of his conceivable plans would be potent enough to stop the creature. Eventually, he settled on the idea of using a powerful explosive spell to serve as a temporary distraction, hopeful that it would buy time for the heroes or even the military to devise a more effective strategy of combating something of that size. Yet, faced with the sheer size of the approaching whale, he couldn't shake the concern that his magical assault might be as useless as a first-years stinging jinx against Hagrid.

Risking a quick glance back to the heroes, Harry was stunned to witness a lone figure, the man clad in ill-fitting clothes, striding purposefully towards the approaching enormous extraterrestrial threat. Confused by the foolhardy move and unsure of the man's motives … whether bravery or a death wish … Harry contemplated apparating down to intervene. However, before he could act his plans were abruptly frozen as the man began undergoing a startling transformation, growing in size before Harry's eyes. Intrigued yet bewildered, Harry observed the change, wondering to himself whether it was a form of self-transfiguration or an animagus transformation.

As the changes finally appeared to cease, Harry was left peering down at a creature that defied easy classification. A combination of man and giant, the figure bore a vague resemblance to the man who had become this thing but now stood larger than Hagrid, its entire form covered with rippling muscles and it was … a distinctive, vibrant shade of green. The unexpected transformation left Harry dumbfounded, unable to move.

In a state of astonishment, Harry observed the colossal, green, hulking figure charge towards the approaching alien whale. The ensuing punch delivered by the monstrous hero brought about an outcome that defied all logic … he managed to halt the creature's momentum, inducing visible cracks forming along its formidable armor. As the back half of the extraterrestrial behemoth started to coil upward, revealing vulnerable spots beneath the damaged armor, Iron Man seized the moment to leap into action.

Launching vertically from the ground, the armored Avenger unleashed a barrage of small projectiles at the exposed flesh of the wounded space whale. Harry stared, wide-eyed, soon realizing that these seemingly small, innocent projectiles were, in fact, explosives. Their detonation upon contact created a spectacular display, blasting the massive creature into fragments that rained down all over the street. The once formidable head of the alien, complete with a fist-sized indent, rolled off the elevated roadway where the heroes had gathered, landing amidst a cluster of abandoned cars below.

Caught up in the spectacle of destruction, Harry involuntarily took a step back from the edge of the building. From this elevated vantage point, he looked down on the gathered heroes and then over the remainder of the city, wondering if perhaps he was actually needed for the fight in the ongoing battle, as he was incapable to that kind of damage. The efficacy of the hulking monster hero and Iron Man's explosives gave him pause, making him wonder whether his magic was truly necessary in the fighting or if his efforts might be better directed towards helping civilians, as he had been earlier, and preventing further devastation to the city, as he looked out and saw that already the damage to the city must be astronomical.

Startled by a loud clamoring of alien sounds echoing from over the opposite side of the rooftop, Harry ran towards the other side of the building, his curiosity piqued. Upon reaching the edge, he peered over, only to be greeted by an unsettling sight. His unease mounted as he beheld hundreds upon hundreds of extraterrestrial beings clutching onto ledges and windows of the buildings, their collective gaze fixated skyward. The air seemed to vibrate with their frenzied screams directed toward the portal looming to his right and above him.

Following the aliens' frantic gestures and shouts, Harry reluctantly risked a glance upward. A curse escaped his lips as he beheld the disconcerting sight … the next wave of alien flyers and space whales appearing through the breach in the sky.

A realization dawned upon him amid the chaotic scene unfolding before his eyes. "Okay … it seems I definitely might be needed for this fight," he murmured to himself, his mind swiftly shifting gears, wondering how best to contribute.

Glancing back at the aliens clinging to the building facades, Harry grappled with the grim reality that him being able to reach the breach in the sky seemed unfeasible. And even if somehow he had access to his Firebolt, closing such a spatial rift appeared well beyond his magical abilities. Accepting this limitation and hoping the superheroes would be able to come up with something, Harry redirected his attention downward, leaning out over the building's edge. With a determined resolve to make a difference, he began casting stunning spells at the invading aliens, while manipulating the very bricks they clung to, transfiguring them into restraints to immobilize the stunned creatures and prevent their fatal falls. He reasoned that someone among the heroes might have some questions and hope to gather information from these invaders.

Amidst his focused efforts, a sudden sound behind him jolted Harry into swift action. Startled, he whirled around to witness Iron Man soaring past the building's roof, before executing a sharp roll and veering off in another direction. He saw that before the flying, armored hero had dropped a figure onto the rooftop before swiftly flying off towards a group of hostile alien flyers engaging in an assault on a nearby building.

Harry watched as the individual lowered onto the rooftop by Iron Man cast a cautious gaze over the building's edge before straightening himself and seemingly engaging in a silent conversation with himself. Noting the distinct and familiar quiver slung across the man's back, Harry moved a step closer, intending to approach him.

However, unbeknownst to Harry, Clint had not noticed Harry's presence on the roof until a slight scuff from Harry's shoe against a piece of the rooftop disrupted the relative silence on the roof. In an impressive display of reflexes, Clint reacted instinctively. He swiftly raised his bow, notched an arrow, and executed a swift spin, instantly targeting his bow on Harry.

Realizing the potential danger based on the archer's accuracy, Harry froze in surprise and hastily raised his hands in a placating gesture and called out, "Whoa, whoa, hold on, Clint! It's me. We're on the same side, remember?"

Clint's initially tense and vigilant demeanor softened, as his intense stare melted into a warm smile as he recognized Harry. "Well, well, look who's still in the game," he remarked, his expression relaxing slightly. "Good to see you, kid. Nat and I were a bit concerned when you vanished on us. I figured you might have decided to be smart, finding a cozy spot to sit this one out. But Natasha was convinced you'd just gone on ahead, continuing the fight elsewhere ..." His words trailed off momentarily as he swiftly redirected his attention, repositioning his bow and loosing an arrow at an alien hurtling toward their rooftop from a passing flyer. Without so much as a glance to confirm the shot's success, he continued, " ... but I'm downright glad I was wrong and you decided to stick around. Even though it sure seems like we've leaped out of the frying pan and straight into the fire." With a sweeping gesture of his free hand, he indicated the ongoing flood of aliens pouring through the breach in the sky.

Pausing to emphasize his point, Clint regarded Harry with a brief yet serious expression. "I don't have any spare earpieces," he admitted, pointing to his ear, "so you won't be able to communicate with the team directly. But we could really use your assistance, situation seems to be getting worse."

Harry's attention was momentarily distracted as a spectacular display of lightning bolts surged from clouds that seemed to materialize out of nowhere. The bolts streaked towards the top of the Chrysler Building and then from there flew straight upwards, targeting the breach in the sky with an electrifying force. The sudden phenomenon appeared to create a temporary barrier, which seemed to stall the influx of additional aliens emerging from the opening.

Shifting his focus back to Clint, Harry affirmed his commitment with a nod. "Absolutely, tell me what you need. Where can I pitch in?" He asked eagerly.

Clint's contemplative pause was evident, his brow furrowed as if lost in the conversation among the team members buzzing through his earpiece. Eventually, he pivoted back to face Harry, and quickly summarized the previous discussion, looking in the direction Iron Man had flown off to moments before.

"Tony's intel indicates a heavy alien presence several blocks in that direction," Clint explained, pointing toward the area Iron Man had departed for. "He planned to handle them or at least divert their attention, possibly guiding them back, but seems he's got his hands full now." There was a slight hint of humor in Clint's tone, "So to speak at least."

"Thor's over there," pointing to the lightning arching up from the Chrysler Building, " He is doing his best to seal off the breach in the sky, trying to stem the alien invasion. And it's a little bit of a stretch for Nat or Cap to cover that distance on foot," Clint continued. "I'm stationed up here … sort of an eye in the sky, as it were, coordinating movements and calling out patterns of alien behavior. And the Hulk …," he paused briefly, a wry grin appearing, "well, he's doing what he does best … smashing. But it'd be good to have him close, just in case another one of those space whale things breaks free."

Gazing in the direction the archer had indicated the aliens lay, Harry recognized the path he had travelled earlier to arrive at this location. His attention focused on the area, noting the presence of numerous alien flyers lingering in that direction, verifying Iron Man's assessment.

Swiveling back toward the archer, he noticed Clint had leaned over the building's edge and swiftly fired off a couple of arrows from his quiver. "I can handle that," Harry affirmed with a determined nod. "But what's the plan for after that?"

Clint's response was marked by a casual shrug, his uncertainty evident. "Can't say for sure. By then, the battle might be settled, and we'll be celebrating victory, or ..." His voice trailed off, before continuing. "We might find ourselves in an entirely different situation. Alien language lessons and slavery, who knows?"

However, he swiftly continued. "But if you get that situation all sorted out and if the fight's still going on or if you bump into any of the other heroes during the fight, feel free to lend a hand wherever needed," Clint advised.

Leaning in slightly, as if sharing a confidential tip, Clint's expression turned slightly serious. "One piece of advice, though: if you encounter the Hulk, thats the big green fellow pulverizing aliens, just don't make him angry." Clint leaned back, a smile on his face. "Trust me kid, you wouldn't like him when he's angry."

With that cautionary note, Clint pivoted back around, shouting a response … likely an acknowledgment or directive which was lost to Harry over the sound of an explosion from the next building … in response to something he heard from his earpiece.

Harry began to pivot, mentally picturing the building that stood across the street from the hotel he had stayed in, readying himself to Apparate. Yet, a sudden thought arrested his movement, prompting him to swivel back toward the archer, a question tugging at his thoughts.

"What are you going to do?" Harry questioned seriously.

Clint's response was resolute and laced with determination. "We're going to make these alien bastards regret the day they decided to come to Earth. We're going to make them regret ever meeting Loki."

Harry stared at him for a second, intrigued by the name drop. However, he shook his head slightly, rephrasing his question. "No, I mean, what are you going to do once you run out of arrows and your quiver runs dry?" Harry gestured toward the quiver which was slung over the man's back, noting it was already half empty.

Clint's facial expression briefly betrayed a sense of uncertainty before a steely resolve settled across his features. "I'll be honest, kid. I'm just a guy armed with a bow and arrows, facing off against aliens pouring out of a hole in the sky. This isn't exactly my usual gig. But that won't stop me from fighting. Even after my last arrow hits its target, I'll keep at it. I'm not completely hopeless without them."

Their conversation was interrupted by a distant explosion, prompting both Harry and Clint to whirl around, scanning the skyline for the source. Failing to identify its origin, they refocused on each other,.

"But that's a problem for me to worry about, not something you need to concern yourself with," Clint continued, shifting the focus away from his own uncertainties. "And speaking of concerns, you best be on your way." He gestured in the direction he had previously pointed out. "Looks like a couple more of those flyers are headed that way. You should go."

Harry solemnly nodded in understanding, taking a couple of measured steps away from Clint, preparing to follow the suggested direction. Yet, a sudden instinct tugged at his thoughts, compelling him to pivot back towards the archer's form leaning over the building. His gaze settled upon Clint's quiver, uncertainty at what he was about to do clouding his expression.

Unaccustomed to creating spells, even at the best of times, Harry harbored serious doubts about his abilities in this realm. However, since his arrival in this unfamiliar world, he had been having these … gut feelings that he couldn't describe … unfamiliar yet strangely familiar inklings. It was as though he felt he possessed knowledge of a spell he had never learned and wanted to use it.

Opting to trust these unexplained instincts, without hesitating Harry murmured an incantation softly under his breath.

"Infinitum Sagitta Reditus."

To his amazement, a warm purple-hued spell sprang forth from his outstretched hand, arcing towards Clint's quiver. He felt a surge of hope as a sense of inexplicable certainty washed over him, as if he knew that this was exactly how things were supposed to happen, and the Clint was about to never have to deal with running out of arrows. When the spell connected with the quiver, its highlighted the quiver in a vibrant shade of purple before the light faded away and everything looked normal.

Harry observed Clint stiffen when the spell connected with the quiver, noticing the archer tense up and swiftly whirl around, seemingly reacting to the impact of the spell or detecting the minor alteration in his equipment.

However, in the blink of an eye, with an audible crack, Harry vanished before Clint had completed his turn, leaving the archer standing alone on the rooftop. A sudden sense of frustration tinged Clint's expression as he muttered under his breath, "Ugh ... I can't stand it when he pulls that disappearing act. Who does he think he is?" His mild irritation evident, Clint turned his attention back to surveying the cityscape, his focus shifting to the ongoing battle and the relentless invasion, unaware as of yet as to what Harry had done.

Meanwhile

Several blocks away from the roof he had been on with Clint moments ago, Harry apparated onto the rooftop of the building across from the hotel he had stayed at the previous night. Before he had even finished taking in the surroundings, he swiftly ducked beneath an awning on the roof, seeking cover as an alien flyer zoomed by overhead, firing its weapons across the street. Harry jumped out to throw a spell in the direction of the alien but was halted, watching it disappear in a sudden explosion. The resultant shockwave rattled the surroundings, debris scattering across the rooftop and street below.

As Harry cautiously rose to his feet, intending to determine the cause behind the flyer's abrupt explosion, a couple of things immediately caught his attention amid the chaos.

As Harry scanned the area, his focus was first drawn to the building across the street from him, the one whose exterior shimmered with an enchantment that rendered the details hazy. Straining his eyes against the magical protection, Harry struggled to discern the figures on the adjacent rooftop. Despite the spell's interference, which seemed to prevent Harry from clearly making them out, a nagging certainty formed in his mind, hinting that one of the individuals on the roof might be the formidable green giant Clint had referred to as … the Hulk. This thought sent a ripple of confusion through Harry, especially when a distant, thunderous roar echoed from blocks away, a sound which Harry had begun to associate with the massive green monster.

However, his attention abruptly shifted as the sound of a distressed young boy's cries pierced the chaotic scene at street level. Deciding to worry about the possibility of multiple Hulks at a later point, Harry pivoted, diverting his gaze toward the source of the cry. Amidst the wreckages of damaged cars, he observed a worrisome sight … one of the dismounted alien appeared to be stalking a woman in her late twenties, who appeared to be shielding a young boy and girl from the menacing creature's pursuit. The trio attempted to flee in the opposite direction, but they were not moving quickly and the appeared to have a slight limp which he couldn't help but feel was a hindrance to their escape. Harry's concern surged as it became evident that the alien was toying with the trio.

Just as Harry readied himself to intervene, a moment of astonishment seized him, a faint smile beginning to form across his face. His attention was captured by the brave actions of the woman, who he presumed to be the children's mother, who had halted in her tracks and started hurling pieces of debris at the approaching alien. She was yelling loudly that the creature leave her kids alone … using some very descriptive language.

After a moment of shock, the alien seemed to recover from its surprise and it raised its weapon. Harry recognized the situation had escalated and the alien was done toying with the family below. Without hesitation, he Apparated beside the courageous woman, causing her to startle at his sudden appearance. Swift as lightning, Harry cast a stunning spell at the alien, the crimson spell zipping through the air and striking the creature in its chest, sending it spinning backwards crashing to the ground.

Expecting relief or gratitude, Harry was taken aback when he turned and found the woman already facing him, a rock clenched firmly in her hand, poised as though prepared to throw it in his direction. Her stance was defensive, her expression guarded, indicating her readiness to defend herself and her children against any perceived threat.

"Leave my kids alone!" Her voice rang with fierce determination as she confronted Harry.

A gentle smile sprang to his face as he raised his hands in a gesture of mock surrender. "Please believe me, I'm here to help. I mean no harm to you or your children," he acknowledged warmly. "For what it's worth I was a big fan of your spirit."

The woman regarded Harry with a look of cautious scrutiny, her weariness evident as she assessed his sincerity. After a tense moment, she inclined her head ever so slightly in concession to his words. Without further hesitation, she spun around to face her kids, who, despite their initial shock at Harry's sudden appearance and the alien's fall, were running towards their mother.

"Frankie! Lisa! Are you okay?" Her voice wavered with a blend of relief and concern as she reached out to gather her children into a protective embrace.

Witnessing the reassuring nods from her children towards her, Harry noticed a slight relaxation in her demeanor. As she turned back to Harry he noticed a subtle easing of the suspicion that had clouded her expression moments ago.

"Thank you so much for your help. I really appreciate it. I … I don't know how we could've managed without your help," she expressed earnestly, her voice carrying a mix of gratitude and relief.

Harry responded, "No worries. It was no trouble at all, I am just glad I was able to help. But for your safety, even with your fighting spirit, it might be best to find shelter. That building over there," he indicated with a nod towards the hotel, "has a basement. You'll be safer down there until the fighting is done. Can you make it there on your own?"

Her response was swift and assertive, her gaze hardening as she addressed Harry. "I'm a military wife, not some helpless person needing assistance crossing the street," she retorted, the pride in her independence evident in her words. Yet, after a second a softer expression quickly replaced her defensive stance. "I'm sorry about that. I'm … still on edge after what happened. I was concerned ... well … I honestly appreciate the help stopping that thing … " Her voice trailed off momentarily, her gratitude evident as she gestured toward the stunned alien. "But we'll be able to manage to reach safety on our own. I'm sure there are others you can help," she added.

With a determined nod, the woman pivoted, signaling for her children to follow her as they started their journey toward the hotel to seek refuge within its confines.

As they set off, they had scarcely made it a couple of strides away from Harry, when the young boy's voice pierced the air. "Does that man work with Dad?" Even amidst all that they had been through, this question apparently caused the woman to chuckle slightly.

"I don't think so, sweetie," she responded with a gentle tone. "I'm pretty certain he's not a member of the military. But let's focus on getting to safety," she urged, emphasizing the urgency of their situation.

Her thoughts seemed to drift for a moment as she added after a second, "I don't want anything to happen to us. Your dad ... lord knows what would happen to your dad if something was to happen to us and he wasn't able to save us … "

The sounds of the mother and her children gradually faded into the background as Harry redirected his attention toward the building that stood cloaked under the mysterious enchantments. He held a strong conviction that whatever seemed to draw the aliens to this particular area of the city likely resided within these walls. Determined, he made his way over to the building and ascended the steps leading to the entrance, the air crackling with a potent aversion charm that attempted to repel his advance. Undeterred, he managed to push through the magical resistance, determined to get answers.

Upon reaching the top step of the staircase, Harry paused on the landing, his gaze fixated on the seal adorning the door. Even up close he had no idea as to its meaning or its significance, although he wondered as to whether Hermione might have been able to decipher its meaning. However, it was at this closer vantage point that he discerned previously unnoticed writing above the entrance, a revelation that captivated his attention. As he studied the letters, they gradually sharpened into focus … "Sanctum Sanctorum."

SamonIllmantrim - Thanks! I am glad you are enjoying it!

ElendorAnardil - Thats fair, wanted to make sure I got right into the action and introduced a bunch of the characters right away. As far as the opening I thought I would do that to provide a recap but changing that up and story notes will only be related to the chapter. No more in story notes from previous chapters that don't relate. Thanks for the feedback though.

Snewp - Thanks! There is a reason he is a little 'underpowered' which he will look into, starts in the next chapter. And then he will attempt to remedy it.

LittleBoyDeath - Will do!

stevemoore9081323 - Of course!

CharleyReyes - I am glad to hear you are liking it! There is obviously so many characters to include and some of them will pop back and have other fun cameos or important contributions. But some might just be one small appearance.

Joe Lawyer - The hostage taking was inspired by the one bank scene where Captain America jumped in. So not so much a hostage as they were just rounding up people.

SanadaTenchi - I am glad you are liking it. Some will be fun drops! Hopefully you managed to figure out who was in this chapter!

stars90 - Thanks! Tried to make it realistic and was happy with how it turned out.

albus potter-greengrass - I guess we will see who ends up with who.

Kind Regards,

Story Note 1 – Harry will still have his magic but won't be able to get a wand for obvious reasons. Luckily as the Master of Death he has an innate ability to use the Power of the Hallows in the new universe. Will primarily focus on the elder wand (will appear as wandless, nonverbal magic) and occasional invisibility. He will have power of the resurrection stone but that will not come up often, as its power is universe dependent so he is not able to call up his mum or dad or Sirius or … whoever else to chat. However, there is an arc planned in this story where he will get to use it

Story Note 2 – This story will be inspired by the MCU – Earth 199999, with specific changes being mentioned when they appear.
