Flowey (offscreen): "Hee hee hee... Oh, this is just TOO perfect!"
The children answer was straight, altogether answer "To get back with our parents." as they were seeking a way to get back to their father in their voidful domain, and they didn't wanted anything from this world, despite there are things they enjoyed, as the time they passed with Toriel, what she did for them as the pies and adjusting the clothes for them. The shows with Metatton entertainning them. The blue magic of Papyrus surprising them. And other few things of the Underground, but mostly, was being with Toriel.
Asgore: "I hope is not much to ask, but would you help the monsters? Your souls seem similar, but also stronger than human souls, I am sure together, you can break the barrier with ease."
Before they could answer, suddenly, roots emerged from the ground, piercing Asgore with ease as he was with the guard down. Then, with high speed, white pellets started forming circles around Asgore, and then quickly moving and impacting him.
After few circles of pellets, Asgore fell to his knees, dusting, and then, a white upside down soul appeared where Asgore was, and a last circle of white pellets surrounded the souls, and after impacting, the soul broke in half, and then shattered and vanishing.
Then Flowey appeared in front of them coming from the ground, where Asgore was.
Flowey: "You IDIOTS! Did you really think you could walk freely everywhere? No no no. I did really enjoy all your show until here, it was very amusing. I must thank you, after all, I couldn't get that old man to show me where he had the human souls, and now that he is dead, but for becoming a GOD I need 7 human souls, but hey, you are 7 after all, with only you, I could become greater than any GOD among monsters. you along the 6 human souls, would make me become the GOD of this timeline, controlling much more than Resets-"
Suddenly, the entire world shakes for a short moment, and Flowey seems very alarmed and nervous, and instantly breaks the jars and grabs the souls on them, absorbing them, and then a white flash blinds everything. After a moment later, a shadow huge immense figure appear before them slowly from the top, it's size is still smaller than the barrier.
Slowly, a huge immense shadow appeared, emerging from the top of their view, and then, everything went back to normal view, and they were in front of a giant immense green creature, with a tv for head, and claws as fingers. But before they could observe, Omega Flowey laughed deeply and loudly, before instantly attacking with it's roots, and bomb falling from the top of them.
All of them got overwhelmed with ease, as the different amount of attacks from Omega Flowey, but also the intensity of them. After short moment, the youngest couldn't continue, falling, and then Omega Flowey grabbed their souls.
Slowly, one by one started to fall, but Kaeltherion remained as the last, and so, Omega Flowey went even harder with him, as with each one of them falling, was a soul Omega Flowey absorbed, obtaining more power.
After a moment, suddenly, A'malther appeared, to see how Kaeltherion fell, and his soul was taken by a root of Omega Flowey.
Flowey: "Ohh~, what's the matter?~ Don't worry, you'll join them soon~"
Then, Omega Flowey transformed after absorbing all the children souls.
Asriel Dreemurr's transformation after absorbing the 6 human souls, and the 7 souls of A'malther's children is a grotesque yet awe-inspiring display of power, combining divine elegance, monstrous dominance, and the overwhelming force of determination. Below is a deep and detailed description of his appearance and magic:
Physical Appearance
Height and Presence:
Asriel towers at an immense height, his form now vast and celestial, standing nearly 20 feet tall, though his presence feels infinite, filling the entire space. His figure radiates raw power, divine beauty, and absolute dread, blending monstrous and godly elements seamlessly. His body moves with an eerie grace that belies its overwhelming strength.
Face and Head:
Asriel's head is a combination of his original goat-like features and an ethereal, divine visage. His fur is pure white, but it glows faintly with shifting rainbow hues, as if reflecting the fractured souls he's consumed. His eyes are deep pools of cosmic light—one glows gold, symbolizing hope, while the other burns crimson, representing destruction. His horns are enormous and twisted, spiraling upward like jagged spires, crackling with electrical energy and pulsating with multicolored light.
Body and Armor:
His chest is adorned with a radiant, golden emblem in the shape of a heart, representing the culmination of all the absorbed souls. The emblem pulses rhythmically, mirroring his immense life force. His torso is clad in flowing, semi-organic armor that appears to be fused with his body, resembling molten gold and obsidian with veins of shifting red and green light. The armor seems alive, moving subtly as if breathing. His shoulders bear massive pauldrons shaped like the heads of snarling dragons, each emitting a faint, otherworldly smoke.
Wings:
Extending from his back are massive, ethereal wings, made entirely of energy. They shimmer with shifting colors of gold, blue, and crimson, with streaks of green and violet outlining each feather. The wings appear both angelic and chaotic, with energy tendrils constantly dripping and reabsorbing into them, leaving faint trails of destruction wherever they move.
Hands and Claws:
His hands are elongated, ending in claws that look sharp enough to rend reality itself. They are wrapped in faintly glowing chains of light, symbolic of his mastery over the power he's absorbed. When clenched, these chains emit a sound like shattering glass, signifying their immense strength.
Legs and Feet:
His legs are muscular and digitigrade, with clawed feet that leave glowing, fiery imprints on the ground. The fur on his lower body transitions to a darker shade, with veins of bright light crisscrossing beneath the surface, as though his body is barely containing the energy within.
Aura:
Asriel radiates an overwhelming aura of despair, hope, and limitless power. Around him swirls a hurricane of colors, each representing the souls he has consumed. The aura bends reality, distorting time and space near him. Shadows flicker unnaturally, and faint whispers of the absorbed souls can be heard, their voices crying out in despair and defiance.
Magic Attacks
1. Soul Fracture Barrage:
Asriel summons massive, radiant shards of energy shaped like hearts, each representing the souls he has absorbed. These shards rain down relentlessly, creating massive explosions upon impact. Each shard releases a wave of despair and determination that forces enemies to their knees.
2. Spectrum Blades:
He manifests dozens of glowing blades in every color of the spectrum, each imbued with a unique element—fire, ice, lightning, darkness, and light. The blades spiral outward before homing in on his target, each one leaving trails of destruction in its wake.
3. Chaos Vortex:
Asriel flaps his wings, creating a vortex of swirling energy that drags his opponents toward him. Within the vortex, time slows, and enemies are bombarded with beams of multicolored light that tear at their souls.
4. Determination Chains:
Golden chains of light shoot from Asriel's hands, binding his opponents in place. These chains sap the willpower of their targets, making it nearly impossible to resist his attacks. The chains can also be used to manipulate the battlefield, pulling enemies into devastating energy blasts.
5. Cosmic Judgement Beams:
From his horns, Asriel fires massive, concentrated beams of rainbow energy. These beams are powerful enough to cleave through mountains, and their energy lingers in the air, creating zones of residual destruction.
6. Soulstorm Rain:
Asriel summons the essence of the souls he's absorbed, creating a storm of energy orbs that rain down from above. Each orb explodes into smaller fragments upon impact, covering the battlefield in chaos.
7. Reality Shift:
Using his immense power, Asriel temporarily alters the fabric of reality, creating shifting platforms, inverted gravity, and spatial distortions. These changes force his opponents to adapt quickly or face devastating consequences.
8. Final Form—True Overdrive:
Asriel's body becomes engulfed in a blazing aura of gold and crimson, and his attacks become faster, more devastating, and nearly unavoidable. In this state, his wings grow even larger, and he moves so quickly that he appears in multiple places at once.
Behavior
Asriel in this form is a mix of theatrical arrogance, childlike glee, and godlike fury. He taunts his opponents relentlessly, laughing as he toys with them. However, there are moments of hesitation and sadness, hints of his true self struggling beneath the overwhelming power.
He sees himself as unstoppable and treats the battle as both a game and a performance. Every attack is grandiose and dramatic, emphasizing his newfound status as the ultimate being.
