The magical dragon and the Eight-Eyed Spider stared each other down. Seconds later, they charged at each other.
The collision of these two colossal creatures compressed the air around them, and the resulting shockwaves easily destroyed vast sections of the surrounding area.
As Alex allowed the magical dragon to battle the Eight-Eyed Spider, he observed the spider curiously.
Though its size was smaller than the magical dragon, the Eight-Eyed Spider held its ground in their clash.
The blood-red energy that formed its body repaired any damage instantly, giving it an edge. Despite being weaker in raw power, its relentless attacks overwhelmed the magical dragon.
After a moment of observation, Alex realized the blood-red energy was an unusually powerful form of chaotic magic unique to the Harry Potter world. This reminded him of the final boss in Hogwarts Legacy—a massive dragon made of the same blood-red energy. Could there be a connection?
The battle raged on. Amid the dragon's agonized roars, one of its wings was torn off by the spider. Its body was then shattered under a relentless barrage of spear-like legs.
In the face of the Eight-Eyed Spider's fearless and continuous attacks, the magical dragon fell.
Of course, this was because Alex chose not to intervene!
If the Eight-Eyed Spider could defeat one magical dragon, it was time to summon Magical Dragon 2.0!
If it could defeat Dragon 2.0, then there would be Dragon 3.0, Dragon 4.0, and so on—until an ever-stronger magical dragon finally tore the spider apart.
Naturally, there was a limit to how strong the dragons could grow, and that limit was Alex's true strength, which was at the multi multiversal level
This was the final battle. Alex and the world's rules had reached a point of no return. The outcome would decide whether Alex devoured the world's rules to become the next OAA (One Above All), or... his true body would obliterate the underdeveloped rules of the Harry Potter world and gain a fragmented version of the world.

Infused with another surge of Alex's immense magical energy, the dragon began absorbing everything around it.
Trees, soil, even the air itself were broken down into their atomic structures and absorbed by the dragon. Transfiguration spells continually repaired and strengthened its body.
The dragon's size grew visibly, stretching from 100 meters to 150, then 200, 250, and finally stopping at 500 meters!
At this immense size, the magical dragon towered over the Eight-Eyed Spider like a mountain.
The spider, now dwarfed by the dragon, seemed as insignificant as a housecat before a tiger.
When it realized that the enemy it had nearly defeated had not only fully recovered but also become far stronger, the Eight-Eyed Spider froze in confusion. Its eight eyes reflected disbelief.
"Seriously?! You can't play fair?!"
The spider, now partially intelligent, instantly understood that it stood no chance against this behemoth. Without hesitation, it turned to flee.
But before it could escape, a massive claw, as large as a small mountain, sliced through the air with a deafening sonic boom.
The claw struck the Eight-Eyed Spider's body, shattering its once-resilient form into fragments of energy that scattered across the ground.
Even in this state, the spider did not die. The scattered energy began writhing and pulling toward the center, attempting to reassemble its body.
But before it could fully reform, the magical dragon opened its maw and devoured all the blood-red energy, absorbing and consuming it completely!

With the spider defeated, Alex gained a fragment of the world's authority.
However, it was not enough to turn the tide.
Without wasting time, Alex continued toward the location of Nagini.
Destroying Nagini—the final Horcrux—would grant him full control over the world's rules, allowing him to devour the entire Harry Potter world!
The Magic Dragon moved toward the depths of the Forbidden Forest. For the colossal creature, which measured 500 meters in length, a few strides covered several kilometers, bringing it to the heart of the forest.
At the very center, Alex saw a dense magical array. At its core, coiled atop a blood-red formation, was a massive crimson serpent—Nagini. Its cold, hollow, and indifferent gaze fixed on Alex, who stood atop the dragon.
This was no ordinary snake. The will controlling Nagini's body was no longer her own but that of the Harry Potter world's rules themselves.
The world's rules had finally taken direct action, pouring all their power into a last stand against Alex.
Alex had no intention of waiting for the "boss transformation" to finish. Without hesitation, he commanded the magic dragon to unleash a torrent of dragonfire toward Nagini.
The flames roared forward, scorching everything in their path, but just as they reached Nagini, a barrier of blood-red energy appeared, stopping the attack.
Simultaneously, the blood-red magical array released streams of ancient, chaotic magic, which merged with Nagini's body, transforming her physical form.
Nagini's body began to grow: 20 meters, 50 meters, 100 meters, 300 meters, 600 meters... until she reached a staggering 1,000 meters in length!
Nagini had become a massive crimson magic dragon, radiating an oppressive power. She now faced Alex's 500-meter-long magic dragon as an equal—or perhaps more.
For the first time, Alex's calm expression showed a trace of amusement. Through his heightened senses, he realized Nagini was far more than she appeared.
Her form could continue to expand, potentially reaching tens of thousands of meters. However, she restrained her size, condensing her power into a denser, higher-quality magical structure.
This refinement made her akin to a steel blade against clay. The same volume, yet the denser material would easily slice through the weaker one.
Under the manipulation of the world's rules, Nagini's evolution was complete. The 1,000-meter crimson magic dragon lunged forward, launching a surprise attack on Alex.
A cone of blistering crimson flames shot toward him, threatening to incinerate him where he stood. Even Alex, as powerful as he was, would be burned alive if he didn't evade it.
But Alex didn't dodge. If Nagini was going to cheat, so would he.
He connected to his true self, instantly channeling infinite power.
Chaos magic surged from Alex into the magic dragon below him. Its body began to expand, matching Nagini's size, and soon it, too, reached 1,000 meters.
But the transformation didn't stop there. Chaos magic continued to wash over the dragon, altering its structure until it became a thunder dragon forged entirely of lightning.
When Nagini unleashed another wave of crimson flames, the thunder dragon retaliated with a storm of lightning.
The collision between their elemental attacks created shockwaves that instantly destroyed the entire Forbidden Forest. The remaining shockwaves rippled outward, threatening both Hogwarts and Hogsmeade Village.
In Hogsmeade and Hogwarts, the wizards combined their efforts to erect a massive Protego Maxima shield, barely managing to block the destruction.
But the battle continued. Each clash of the two colossal dragons sent out more devastating shockwaves. Every strike could obliterate Hogsmeade or Hogwarts if not intercepted.
The wizards fought to maintain the protective barrier, but their strength began to wane. No matter how many joined forces, they couldn't hold back the unending waves of destruction forever.
Another few strikes, and both Hogsmeade and Hogwarts, along with their centuries-old histories, would be reduced to rubble.
Hogsmeade's residents began to despair. A villager cried out:
"No! At this rate, we'll all die. We have to do something!"
Another villager, pale and despondent, muttered:
"There's nothing we can do. Whether it's Alex or the monster fighting him, both are far too powerful for us. Our spells wouldn't even reach them—they'd be torn apart by the terrifying magical turbulence long before."
The other villagers fell silent, their hopelessness palpable.
Suddenly, one villager exclaimed:
"Look! It seems like they're moving away!"
Everyone turned their attention toward the battlefield. In the distance, the two colossal figures, towering like mountains, were engulfed in fire and lightning as they ascended into the sky, continuing their clash far above. With every collision, they moved farther and farther away from the village.
As they receded, the shockwaves weakened, eventually dissipating into nothingness.
The villagers exchanged glances before embracing their loved ones tightly.
They had survived.
Meanwhile, the young wizards of Hogwarts witnessed the same scene. Even those who were somewhat familiar with Alex's immense power found themselves in disbelief.
"Could Alex truly be Merlin reincarnated? How else could he be this powerful? This strength has already surpassed the realm of wizards!"
It was undeniable—Alex's current abilities made him capable of defeating any Muggle nation, surviving even in the center of a nuclear explosion.
To ordinary people, he was indistinguishable from a god.
Severus Snape, observing the two titanic figures retreat into the distance, exhaled deeply before turning to Albus Dumbledore.
"Headmaster, what exactly is the creature fighting Alex? Could such a being exist within the wizarding world?"
Dumbledore remained silent, his expression troubled. He, too, had never encountered anything like this before.
The power those two wielded was beyond comprehension. Either one of them could effortlessly destroy the entire world.
They didn't seem like creations of this world. If the wizarding world had previously been a low-magic domain, Alex's arrival had elevated it to a mid-magic world. And now, with this battle, it had reached the level of high magic.
After a long pause, Dumbledore shook his head, his voice tinged with uncertainty.
"I don't know, Severus. The creature does bear some resemblance to ancient magic, but even ancient magic could never achieve this level of power. Don't dwell on it too much. Instead, we should hope for Alex's victory."
He added with a grave expression:
"Unlike Alex, we know nothing about that creature. If it's an evil being and manages to defeat Alex, it might very well destroy this entire world."
Snape nodded in agreement.
"You're right, Headmaster."
The World Rules: "Rubbish! I'm the righteous one here! That guy is the villain! He's the invader!"
...
In the skies, the Thunder Dragon and Nagini continued their relentless clash. Crimson flames and dazzling lightning illuminated the heavens, dyeing the entire world in hues of red and blue.
The roaring fire and crackling lightning erupted constantly, creating deafening explosions high above. Their battle stretched across vast distances, with its effects reaching farther and farther as time went on.
The sky grew ominously dark, as if signaling the end of the world.
In yet another collision, half of the Thunder Dragon's body was destroyed. It looked battered and miserable, yet Nagini was in an even worse state.
Most of Nagini's body had been shattered, with crimson energy burning like fire at its wounds, trying desperately to heal them. But its strength was nearly depleted, leaving no energy to fully reconstruct its body.
Seeing this, Alex prepared to deliver the final blow, ready to destroy the last Horcrux once and for all.
But just as he moved to strike, something unexpected occurred. Nagini's aura and magical energy surged exponentially. The once-depleted energy began to rise rapidly. Magic from hundreds, even thousands of kilometers away, was drawn toward Nagini, pouring into its body and strengthening it further.
Facing the increasingly powerful Nagini, Alex didn't grow angry. Instead, he smiled.
"So, this is your last resort, isn't it?"
Indeed, the abnormal scene unfolding before him wasn't caused by anything else—it was the work of the World Rules.
After following its own set of rules and strengthening Nagini to its limit, only to have it still lose to Alex, the World Rules found itself on the brink of being devoured. Pushed to desperation, it snapped and resorted to irrational actions.
Breaking its own established rules, it disrupted the natural order of the Harry Potter world and forcefully elevated Nagini's power beyond its limits.
By now, Alex's avatar was no longer a match for Nagini. But his true opponent was never Nagini. It was always the World Rules.
And for the World Rules, its true adversary was not Alex's avatar—it was his true form, waiting outside.
As Alex's avatar smiled, his true form mirrored the expression.
When the Harry Potter World Rules broke its own limitations, it created a precedent, giving Alex the justification to do the same. Now, he too could bypass the Harry Potter world's restrictions.
Taking a single step forward, Alex used his control over the world's authority to forcibly enter the Harry Potter world. He appeared directly in front of the Thunder Dragon.
His avatar merged back into his true form. Staring at the ever-growing Nagini, Alex scoffed:
"In the end, you're just an immature World Rule—far from the wisdom of the OAA. You've dug your own grave!"
He sneered.
"If you hadn't disrupted your own rules, it would've taken me much more effort to fully devour the Harry Potter world. But since you've destabilized it yourself, now it's all too simple!"
