DOOM CASTLE
Third Person POV
Aethereon raced along the narrow cliff path behind the castle, the air around him prickling with raw, violent energy.
Whatever this is… It's bad, he thought, jaw tightening. The power he sensed wasn't just strong—it carried a suffocating weight, a dread that clung to his skin.
As he stepped into the clearing, the sight that met him froze his breath. The altar—built by none other than Doom—stood like a wound in the earth. And what it held made Aethereon's stomach knot.
A dry, almost disbelieving chuckle escaped him.
"Today's gonna be a long day…"
Three massive portals yawned open behind Doom, swirling with unstable colors. The man himself knelt in the center of a complex runic diagram, his hands raised as streams of magic poured into the runes drawn on the floor of the altar. His back was facing the portal.
Whether he even realized what he was bringing into the world or even know there are portals behind him … Aethereon doubted it.
Inside the glowing circle of the runic diagram, humans burned—engulfed in eerie green or red flames—thirty of them. No screams, no thrashing. Their bodies stood rigid, hollow eyes, as if their souls had already been claimed by something unspeakable.
The image burned itself into Aethereon's mind, and he knew it would haunt his sleep.
No words. No dramatic entry.
He blurred into motion, vanishing as he entered into super speed. The sound barrier shattered behind him. Time slowed.
He soared upward, a massive Rasengan swirling into life in his palm, its energy roaring against his skin. His gaze flicked once toward the victims.
"…Sorry, I couldn't save you."
Althought Baron might be full guilty for the death of Doom's father but villagers might have also been manipulated by Mephisto for the death of Doom's mother how could they know mystic arts do they even know at first they were happy as Synthia could help and heal them but they turned against her so suddenly it might be the work of none other than Mephisto who make shady deals just for amusement.(info from ancient one)
He dropped the attack straight onto the center of the circle. The Rasengan hit like a meteor, tearing the floor apart. In the frozen slowness of his speed, he watched debris peel away from the ground in slow arcs. The ruins split apart beneath the pressure before the sound even caught up.
Doom, mid-ritual, was ripped into the air by the shockwave. The three portals shuddered violently before collapsing—two sealed completely, but one still pulsed, half-open, like it had been waiting for its companions to join it.
Aethereon's eyes narrowed.
In the stillness of his accelerated world, he drifted toward Doom seeing some green aura slowly emerging on his body to protect him alex was stunned by the instinct to protect himself, catching the man mid-air. He gave a small push—just enough to knock him away from the portal.
Doom is not as evil as depicted, if he has even a shred of humanity, he might become an ally who stands together for protection from external threats to Earth.
So Aethereon need him to understand what is he doing and who is the real culprit.
Time snapped back to normal.
BOOM!
First came the deafening roar of the Rasengan's explosion. Then, a shimmering shockwave rippled through the air, flattening the grass and snapping Aethereon's cape to the side.
He glanced toward the half-open portal. In the distance, Doom's body was hurled away, skidding across the earth and smashing through several trees before finally coming to a halt, dirt and splinters scattering around him.
Doom groaned, coughing hard. "Ughh… cough—cough…" His vision swam, but when it cleared, his eyes locked onto the stranger in front of the portal. Rage boiled instantly.
In his mind, the pieces connected—wrongly. This man must have come from that portal. He must have destroyed the ritual. And now… his mother could never return.
He charged, green electricity snapping across his gauntlets, wind whipping his cloak.
"WHAT DID YOU DO?!" he yelled with rage.
His speed caught even Aethereon off guard. How…? He's moving this fast purely on magic? Aethereon had thought Doom could only push himself this far with a mix of tech and sorcery—not pure mystic art.
Doom's fist cracked with lightning and slammed forward. Aethereon twisted aside, delivering a smooth counter-kick—but Doom, instead of blocking, punched his own gauntlet. The blast scattered the stored electricity in all directions, forcing Aethereon to take most of the hit.
Static crawled over his suit as he skidded back, jaw tightening.
Doom planted his left hand against the ground to steady himself, his eyes narrowing.
"You dare challenge Doom?" he snarled, raising his gauntlet. Arcane energy flared and split into a barrage of glowing bolts, each one homing in with deadly precision.
Aethereon didn't blink. He flickered out of sight, and the bolts sailed straight into the open portal—slamming into a cluster of demons that had been moments from spilling out.
He reappeared mid-air, kunai in hand, marked with a Flying Thunder God seal. With a flick, it cut through the wind toward Doom—Aethereon teleporting to it in an instant and driving a controlled punch into Doom's chestplate. Only 50% of his strength, but the impact still blasted Doom backward through the back wall of his own castle.
The earth gnawed by the impact of sonic boom.and castle wall tattere and even the cliff edge got oliberated and rocks debris flung in air.
WOOSHH!
Before Doom could fully recover, Aethereon was already there—he kicked Doom to the sky, then he vanished from below, reappear mid air where Doom was kicked then punched straight to his face, vanish again—hitting him in a relentless rhythm before ending with a vertical heel drop to the helmet.
Doom plummeted, smashing into the ground with an earth-cracking thud.A massive crater was bloomed by the impact doom figure resembles one of the 2 the refrence king -Yamcha.
"You were saying something about a challenge?" Aethereon landed lightly by the fresh crater.
Doom, buried in rubble, shook his head to clear the ringing in his ears.
His eyes blood shot and his ribs were cracked even though his armor was not damaged much meaning because of the shock waves his body was injured doom who was only getting besten thought alex was using some kind of teleporting ability.
He cast a quick incantation from the Tome of Zhared-Na, and the ground trembled. Mystic sigils burst to life around them, warping the air.
As he guessed Aethereon ability related to space.
Even though his ribs were cracked and injure the only thing that makes Doom's body fight is rage.
A 100-meter null zone. No teleportation.
Sensing he couldn't teleport again, Aethereon took the close combat stance.
The Fantastic Four arrived on the scene, ready to back Aethereon—but the sight of demons pouring out of the portal pulled their focus. Without a word, they moved to intercept the demon army.
Sensing their arrival, Aethereon smiled slightly. At least they'd understand what kind of battle this was now. He formed a quick seal, and with a burst of smoke, eight shadow clones stepped forward.
Doom flinched. This is cheating.
"Help the Fantastic Four," Aethereon told his clones. "I'll handle him." He glanced back at the clones.
And maybe I'll try the greatest jutsu in the universe… Talk no Jutsu. He said inwardly
Doom's lip curled as he saw all the clones left. He channeled his gauntlet—not mixing lightning and magic this time, but pouring in raw, condensed arcane energy until it formed a crackling sphere. He hurled it at Aethereon.
Aethereon raised his ring to form a barrier, holding it for three long seconds before it finally broke the energy sphere apart.
Doom raised his hand again, energy crackling—but it was only a deception.
Before Aethereon could process it, Doom's figure flickered forward. For the first time, shock flashed across Aethereon's face. Impossible… his combat speed? Very few could bypass his eyes at this level, unless they wielded broken powers tied to space or time.
Aethereon braced himself, arms up to guard his face. But the strike never landed. The Doom before him dissolved like a phantom image, vanishing in ripples of distortion.
Too late—he realized.
The real Doom surged from behind, his fist coiled with fire and thunder, both elements snarling together in violent unity.
BOOOOM!
The punch slammed into Aethereon's jaw. His guard dropped a fraction too soon, and the sheer force hurled him backward. His body skidded through the forest in a brutal streak, crashing through trees and smashing boulders apart before grinding to a halt.
He rose slowly from the debris, dust falling from his shoulders. His cheek still tingled with scorch marks, his chest numb from the impact. Yet, instead of frustration, a rare gleam lit his eyes—excitement.
It had been the first since someone had knocked him back like thisand it won't be the last for sure. Doom's illusions—his instinctual, desperate cunning—were a true game changer. And the fact that Doom had only awakened his new power two weeks ago… remarkable.
Unlike fantastic four who are not even clearly using their power they have it easy because they only fight mutants who aren't even properly well fed and not even properly came out of their emotional factor being clung with with their powers.
Aethereon's lips curved. So this is what it feels fighting someone who really knows what he is doing with his abilities and strenght…
He looked upward. Doom wasn't standing before him. He was already above, descending fast—an orb of raw eldritch magic writhing in his palm, its energy screaming against the sky.
Without hesitation, Aethereon thrust out his hand. Chakra spun into existence, swirling with such intensity the very air began to shear apart. Wind shrieked around him; static snapped and bit at the ground. The Rasengan howled louder and louder as he fed it more power, arcs of lightning dancing along its surface.
Doom narrowed his eyes, smile hidden beneath his mask. Yet he didn't falter—his body was battered, ribs cracked, but his will was unshaken. His magic roared brighter, feeding the flame.
Their gazes met—two warriors, no words exchanged. No bravado. No need for speeches.
They both knew the truth.
This clash wasn't about ego. It wasn't about proving strength.
It was about defeating him.
Doom descended with a defiant roar, eldritch fire spiraling around his fist.
Aethereon surged upward, Rasengan blazing with lightning and wind, a shuriken-shaped storm within his palm.
Their powers collided.
BOOOOOM!!!
The explosion tore reality apart. The ground buckled, the forest shredded, and the very wind was blasted outward in concentric shockwaves. The sky flared white as electricity spiraled across the dome-shaped blast.
Even from the battlefield's edge, the Fantastic Four froze, astonished. The forest had become a searing white sphere, its edges rimmed with crackling lightning. The force of it bent trees flat, shook the earth, and drowned out all other sound.
When the shockwave subsided, Aethereon's silhouette remained standing at the crater's center. His breath came heavy, but his body was already repairing itself—flesh stitching, bones realigning, his vitality restored by the Fountain of Youth.
His armor which was damaged at his right side was repairing itself as it shimmered and expand as the nanotechnology being helpful his mask which was also cracked from the punch earlier also started repair itself.
Not far away, Doom's body was flung from the crater, armor sparking and scorched. Aethereon had instinctively angled the blast at the last moment, sparing Doom from the deadliest core of the Rasengan.
Even so, Doom hit the ground hard. His left arm hung stiff, his gauntlet cracked. His ribs ached beneath the armor, internal damage biting deeper than the steel had shielded.
But he was alive.
Barely.
And slowly—ever so slowly—his mystic arts began knitting the wounds together. Not fast, not clean, but enough to keep him standing.
He spat blood into the dirt, eyes blazing beneath the mask. Pain burned through every nerve, yet his will refused to collapse.
Because rage still fueled him.
Aethereon surged forward, creating a containment cell that encased THE THING previously confined at the Baxter Building. Now, Doctor Doom found himself trapped inside as the situation calmed slightly. Doom began to calculate his next move, realizing he couldn't simply bypass this predicament with brute strength.
"Doom… the thing you've been speaking to since you came here—it's not what you think. It's far more sinister. We didn't make that portal—it's yours. And you opened it by sacrificing dozens of innocent lives." Alex voice sharpened, a hint of anger finally breaking through.
Doom hesitated, a flicker in his eyes. But he forced it down, shaking his head.
"My mother would never lie to me. Don't try to interfere. Whoever you are—you'll pay for standing in my way."
Aethereon stepped forward through the haze, eyes locked on Doom.
His voice cut through the roaring wind like a blade:
"Don't try to deny it, Doom. Even you can feel it—something's wrong here. You're just turning a blind eye to it."
Doom's eyes narrowed behind the mask, but he didn't speak.
"You claim it's your mother. That means he's using your greatest weakness against you." Aethereon's tone sharpened, each word deliberate. "The one behind all this… is Mephisto. Ruler of Hell."
A faint tremor ran through Doom's gauntlet, but he stayed still.
"He doesn't care about you. He just wants chaos—either for his own amusement or because he's bored. Think, Victor. If your mother truly told you to do these things, would she ever force her ideology on you? Wouldn't she ask your choice?"
Aethereon's gaze hardened.
"The truth is cruel—your mother's soul isn't guiding you. It's trapped. And the one who bound her there… is the same one manipulating you now, he also manipulated those who killed your mother." (This was told to him by the ancient one.)
Silence. Only the distant, guttural screeches from the portal filled the air and the fighting being help below the cliff.
Doom turned his head downward toward the altar. Grotesque, clawed demons poured from it in waves, their bodies writhing as they came straight from hell. The sight hit him harder than Aethereon's words—like a truth he'd buried, clawing its way back to the surface.
His shoulders sagged. Slowly, Doom dropped to one knee—not in surrender, but in exhaustion. What he had hoped would bring him peace… had brought only more darkness.
and the green cell shimmered slightly and disappeared.
Step. Step.
Boots crunched the rubble in front of him. A gloved hand extended into his view.
"We can still end this, Doom. Believe in yourself."
Doom's gaze rose to meet Aethereon's. Doom's fingers twitched. His mind churned.
And then—he grabbed Aethereon's hand.
With a violent yank, he pulled the man forward and forced himself to his feet, a sly grin curling beneath the mask.
"Don't look down on Doom, you arrogant bastard. You still owe me a beating."
Without looking back, he strode toward the battlefield—still limping, but with the weight of purpose in his steps.
```````
A Few Minutes Earlier
"DAMN IT!" Johnny roared, unleashing a wave of fire that engulfed the horde. Flesh blistered, eyes burst from heat, limbs melted into charred stumps—yet the demons kept coming, clawing forward through the inferno without slowing.
Johnny's heart kicked hard against his ribs. They're not even feeling it… like mindless beast not worrying about anything happened to them they just want to slaughter.
Below him, Susan hurled a massive force field into a towering, bull-headed demon, trapping it mid-air. Her face tightened with effort as she crushed the sphere smaller and smaller until the monster's bones splintered with a wet crack.
"Yooo!" Ben shouted over the chaos. "Who wants to catch THIS punch?!"
A shadow fell over him. He looked up—too late. A giant, bird-like demon dove from the clouds, beak wide and glistening.
CRACK!
The creature's skull exploded into gore before it could strike, its body tumbling to the ground. Ben stood where the punch had landed before he turned to punch others and smash them to bits.
Reed's visor scanned the rift. Numbers flickered across the display. Still no sign of Aethereon.
"Anything?" Susan called, flinging another barrier to intercept a charging fiend.
Reed shook his head. "Too complex. Maybe… maybe we could open a second portal—link it to their dimension. Force them back through the rift."
Susan's eyes flicked toward the portal, then back at him. "Feasible… but the energy cost would be insane."
"I know," Reed muttered, but he didn't stop calculating.
A thunderous ROAR tore through the ground as a tiger-shaped demon lunged. Susan's barrier flared, halting it mid-pounce. Johnny dropped like a meteor from above, flames trailing as he smashed the creature into the dirt and burned it to ash.
Thump… thump…
The ground quaked with each step as a hulking figure emerged from the portal—a Taurus-like demon, bull-headed, with a massive war hammer gripped in its clawed hands. Its red eyes locked onto Ben, the closest target, and with a guttural snarl, it spun the weapon in a deadly arc.
WHRRR—SLAM!
The hammer connected with bone-crushing force. Ben didn't even have time to react before he was sent flying, tumoring through the air and slamming into the ground hard enough to leave a crater.
"BEN!" Johnny roared from above, flames surging hotter around him. His eyes locked on the demon—only for a blur to streak past him.
Eight Aethereon clones tore across the battlefield, their hands glowing with condensed, spinning energy. Each formed a perfect Rasengan, the air around them screaming with rotational force.
They struck in unison.
KRRAAA-THHMM!
The demon's flesh twisted and churned under the crushing vortex before its massive frame was shredded apart, collapsing into a mangled heap.
Susan and Reed rushed over, Ben groaning as he pushed himself out of the crater, dusting off debris. His eyes flicked between the 8 identical figures. "Okay… either I hit my head way too hard, or there's more of you."
Reed's gaze narrowed, scanning them with his visor"Cloning ability?"
One clone nodded. "Yes. But the real one is still occupied—engaging Doom. We know he's responsible, but that doesn't mean he wasn't manipulated."
Reed considered this, then nodded slightly. Susan stayed quiet, eyes fixed on the distant flashes of the Doom–Aethereon clash.
"It's SHIELD's problem what happens to Doom," Reed muttered. "We can't just kill or imprison him, we would create a power vacuum in Latveria—or worse, a war. Well, this is not a problem right now for this portal. My calculations suggest I can link this portal to another, forcing them to collapse into each other."
The middle clone shook his head. "The real one has a plan. We need to hold them off until he returns."
Reed opened his mouth to argue, but Susan cut in. "We're here because of him. Most of the work has been done by him. We will wait." She glanced at Reed—he gave a reluctant nod, though the glint in his eyes said he was still thinking about the idea.
A deep roar shook the air as another Taurus demon stepped out, nearly identical in size and fury. Smaller beasts scrambled past it, only to be intercepted by Ben's crushing punches and Johnny's wall of fire.
"We can only use that move three more times," the middle clone warned, wind blade like chakra forming in his hands. "Stay sharp."
But before they could charge, a blinding white energy tore through the air—its spinning edges shaped like a massive shuriken, its center a pulsing sphere.
WHHRRMM—BOOM!
The Taurus demon was obliterated mid-roar, the explosion forming a dome of pure energy that carved every nearby demon into pieces.
"The real one is here," a clone said—and in that moment, all eight vanished in a wisp of smoke.
From the treeline, two silhouettes emerged without a word. Aethereon, katana in hand, and Doom, cloak billowing. They launched straight into the horde—hundreds of demons still clawing forward, relentless despite the slaughter. Johnny and Ben had already taken down at least fifty, but these creatures didn't care about survival—they only wanted to kill.
Aethereon's chakra reserves were nearly drained from the constant fighting,and couldn't perform more rasengan or use space time ninjutsu.
He shifted into pure matter manipulation, his fiery-red katana burning with condensed energy. Doom's eyes lingered on the blade for a brief moment.
Vibranium.
He recognized it instantly—rare beyond rare. Doom had sought it before, but dealers refused to sell to him, fearing he'd kill them and take it all.
"Pretty impressive resource you've got there," Doom said evenly, his tone unreadable.
"Here take this" Alex said as he throw a small replica of healing potion seeing the one leg and one hand stiff and muscles twisted which was clearly mean the bones are broken.
Seeing this Doom stared at Aethereon for a moment and drank half of the potion and after a second his injuries were healed not instantly but the speed was improved.
"Don't try to put half of it in your pocket you thief"Aethereon said doom hearing this blushed with embarassment slightly under his stoic armor mask and drank it fully with 'tsk' sound.
He was clearly thought of researching it later after he drank Alex took the bottle again and stored in inventory.
As Aethereon make a sword stance Doom was clearly intrigued as before he didn't bring out this sword in fight between both of them.
Aethereon didn't even glance at him again, the tip of his blade lowering toward the nearest demon. "Don't blink, Doom. You might miss something."
[Sun Breathing 15th form - Crimson sword]
In the anime world, shouting the name of an attack might be dramatic, but here it wasn't necessary or people might tell him does he have 8th grade sybdrome.
Aethereon stayed silent. His katana's edge shimmered faintly — fire chakra licking along the blade — the steel's purple tint catching the faint light. Across from him, the demons stood without a flicker of fear in their hollow eyes; they existed only to kill.
Aethereon's gaze sharpened, predatory and cold. In the next instant, he moved — at Mach 18 not even a after image was there, sound barrier broke— and he reappeared at the front of the portal in less than a heartbeat. Behind him, thin white lines appeared on the bodies of the demons.
Then, with a soundless pause, they fell apart. Some split cleanly, dead before they could feel pain. Others shrieked — ragged, wet cries of agony — as their bodies crumpled. Johnny, who had never heard such a sound from these creatures, even when burning them to ash, felt a chill crawl up his spine.
If he ever pulls that sword on me… I'm running.
In two seconds, Aethereon had cut down twice as many demons as Johnny and Ben had managed in several minutes. He stopped briefly — and that hesitation was all a winged demon needed. It dove from the sky, claws outstretched, the air splitting around it.
But before it could strike, a bolt of green lightning tore through its chest. The creature convulsed midair before slamming into a cluster of its own kind, scattering them like rag dolls.
Doom, standing like a javelin thrower mid-pose, lowered his hand with a smug smirk aimed straight at Aethereon.
"Show off," Aethereon muttered, casually brushing demon gore off his shoulder before glancing at Johnny. "Hold position. If even one of these things gets loose, people will die before anyone can put it down."
He turned slightly, voice dropping into command. "And tell Susan not to worry about the portal. I can close it. Just keep a barrier up so they don't scatter."
Because of susan constantly using force field to not let these monster wander off from here.
As his clones vanished, the conversation he'd overheard from Reed and Susan flashed in his mind. For now, there was only one priority — purge this infestation before sealing the gate.
Doom, hemmed in by a swarm of avian demons, eyes bloodshot from exertion and frustration, tore his hand through one like a blade. His arm punched clean through its ribcage and emerged on the other side, dripping black ichor. Mystical energy spiraled into his palm, coalescing into a violent arc before he unleashed it — the Bolt of Bedviement — at the flock ahead.
A hurricane of destruction ripped through them, feathers and flesh spinning into the dust. It was the same spell he had once hurled at Aethereon, back when it had been stopped cold by the green lantern barrier.
For someone with barely two weeks of arcane training, Doom's ability to wield even a handful of high-tier spells was absurd. But then, Mephisto himself had crammed the fundamentals of sorcery into Doom's mind — not for charity, but to move his schemes along… or for his own amusement.
The fight dragged on, demons spilling through the portal like vermin from a flooded nest.
Aethereon had enough.
He stopped himself sword in his hand disappear, Doom who was showing off also looked at Aethereon to see how powerful is he as he knew Aethereon was not using full power when he fought with him.
He tapped the green lantern ring twice. Power surged through him, sweeping away the dull ache of fatigue and replacing it with a sharp, intoxicating rush. His blue aura flared green; the V-shaped mark on his mask shifted color to match.
{IMAGE}
Johnny, watching from the sidelines, lit up with childlike awe. "Awesome…" he breathed, eyes gleaming like a kid seeing a new toy mid-battle.
A blinding emerald radiance filled the sky. Ten colossal green fists — each the size of a building — manifested above like the hands of an angry god and slammed down.
BOOM. BOOM. BOOM. BOOM. BOOM.
Ten times, the ground trembled as demons were flattened into paste, the earth itself groaning under the impact.
Doom watched, arms crossed, his expression caught somewhere between admiration and irritation.
Because the one who could defeat was this strong but also he didn't use his fullpower against him.
Also this was still his territory, being turned into a slaughterhouse, and no ruler would like his backyard to be flattened.
When 90% of the demons were reduced to pulp, Aethereon formed a solid green barrier before the portal. Any fresh demons that emerged smashed against it, wailing and thrashing in frustration, unable to breach.
Aethereon rose into the air, drifting toward Reed and Susan, who were shielded by the Susan force field; that's why no demons were going else where. Both stood off to the side, not fighting — drained from their earlier skirmish with Doom's bots. He didn't bother commenting; their posture already said enough.
Johnny and Ben arrived moments later, bloodied and exhausted but victorious over the last stragglers.
Reed's eyes met Doom's. Doom's jaw clenched — Reed was the last person he wanted to see, especially knowing the blame for this mess lay squarely on him this time. The silence between them was sharp enough to cut steel.
Aethereon coughed deliberately, breaking the tension. Reed only smirked at Doom, the expression saying See, even you can screw up.
Behind his mask, Aethereon's stare flicked between them — his silence carrying its own meaning: Reed, you're the last one who should be talking about it.
"I have a way to close the portal," Reed announced, ignoring Susan's earlier warning to stay out of it as he looked at Aethereon.
Still half-focused on maintaining the green barrier around the portal, Aethereon gave him a slow once-over before speaking. "Alright. Let's hear this great plan."
Reed pulled out a visor-like device, its outer shell looking suspiciously like an old Nokia phone. The screen scrolled with dimensional energy readings, spikes, and waveforms flickering.
"We can connect the node of this portal to another and reroute it away from Earth."
